    "content": "# Scalene Development Guide\n\n## Project Overview\n\nScalene is a high-performance CPU, GPU, and memory profiler for Python with AI-powered optimization proposals. It runs significantly faster than other Python profilers while providing detailed performance information. See the paper `docs/osdi23-berger.pdf` for technical details on Scalene's design.\n\n**Key features:**\n- CPU, GPU (NVIDIA/Apple), and memory profiling\n- AI-powered optimization suggestions (OpenAI, Anthropic, Azure, Amazon Bedrock, Gemini, Ollama)\n- Web-based GUI and CLI interfaces\n- Jupyter notebook support via magic commands (`%scrun`, `%%scalene`)\n- Line-by-line profiling with low overhead\n- Separates Python time from native/C time\n\n**Platform support:** Linux, macOS, WSL 2 (full support); Windows (partial support)\n\n## Build & Test Commands\n\n```bash\n# Install in development mode\npip install -e .\n\n# Run all tests\npython3 -m pytest tests/\n\n# Run tests for a specific Python version\npython3.X -m pytest tests/\n\n# Run linters\nmypy scalene\nruff check scalene\n\n# Run a single test file\npython3 -m pytest tests/test_coverup_83.py -v\n```\n\n## Project Structure\n\n### Core Profiler Components (`scalene/`)\n\n- **`scalene_profiler.py`** - Main profiler class (`Scalene`).

Sampling heap allocator. Key constant `NEWLINE` must match Python config.\n- **`memcpysampler.hpp`** - Intercepts `memcpy` to track copy volume\n- **`pywhere.hpp`** - Tracks Python file/line info for allocations\n- **`samplefile.hpp`** - File-based communication with Python\n- **`sampler.hpp`**, **`poissonsampler.hpp`**, **`thresholdsampler.hpp`** - Sampling strategies\n- **`scaleneheader.hpp`** - Common header definitions\n\n**Sources (`src/source/`):**\n- **`libscalene.cpp`** - Main native library (loaded via `LD_PRELOAD`)\n- **`pywhere.cpp`** - Python location tracking implementation\n- **`get_line_atomic.cpp`** - Atomic line number access\n- **`traceconfig.cpp`** - Trace configuration\n\n### Vendor Libraries (`vendor/`)\n\n- **`Heap-Layers/`** - Memory allocator infrastructure (by Emery Berger)\n- **`printf/`** - Async-signal-safe printf implementation\n\n## Key Patterns\n\n### Python Version Compatibility\n\nThe codebase supports Python 3.8-3.14. Version-specific code uses:\n\n```python\nif sys.version_info >= (3, 14):\n    # Python 3.14+ specific code\nelse:\n    # Older Python versions\n```\n\n**Type Annotation Compatibility (Python 3.8/3.9):**\n- **Do NOT use `X | Y` union syntax** in runtime-evaluated annotations (PEP 604 requires Python 3.10+). Use `Optional[X]` or `Union[X, Y]` from `typing` instead.\n- **Do NOT use `list[X]`, `dict[K, V]`, `tuple[X, ...]`** in runtime-evaluated annotations (PEP 585 lowercase generics require Python 3.9+). Use `List`, `Dict`, `Tuple` from `typing` for 3.8 support.\n- Adding `from __future__ import annotations` makes all annotations strings (not evaluated at runtime), which allows modern syntax on older Python. However, this can break code that inspects annotations at runtime (e.g., dataclasses, pydantic).\n- The safest approach for this codebase: use `typing.Optional`, `typing.Union`, `typing.List`, `typing.Tuple`, `typing.Dict` in all annotation positions that are evaluated at runtime (function signatures, variable annotations outside `if TYPE_CHECKING` blocks).\n\n**Python 3.13 Changes (`dis` module):**\n- `dis.Instruction.starts_line` changed from `int | None` (line number) to `bool`\n- New `dis.Instruction.line_number` attribute (`int | None`) added for the actual line number\n- On Python < 3.13, `starts_line` is only set on the **first** instruction of each source line; use a line-tracking loop to propagate line numbers to subsequent instructions\n\n**Bytecode/Opcode Compatibility (`dis` module):**\n- **Never match specific opcode names** (e.g., `JUMP_BACKWARD`, `JUMP_ABSOLUTE`, `POP_JUMP_IF_TRUE`). Opcode names change across Python versions — for example, Python 3.10 while loops use `POP_JUMP_IF_TRUE` for backward jumps, Python 3.11+ uses `JUMP_BACKWARD`, and `JUMP_ABSOLUTE` was removed in 3.12.\n- **Always use abstract `dis` module categories** when possible: `dis.hasjabs` (absolute jump opcodes), `dis.hasjrel` (relative jump opcodes), `dis.hasconst`, `dis.hasname`, etc. These are maintained by CPython and work across all versions.\n- For call detection, matching `opname.startswith(\"CALL\")` is acceptable since that prefix has been stable, but prefer opcode integer sets over name strings for hot paths.\n- When checking jump direction (forward vs backward), use `instr.argval` (which `dis` resolves to an absolute offset) and compare against `instr.offset`, rather than relying on opcode names to imply direction.\n\n**Python 3.14 Changes:**\n- `argparse` now has built-in colored help output (`color=True` parameter)\n- `RichArgParser` uses Rich for colors on Python < 3.14, native argparse colors on 3.14+\n\n### Argument Parsing (`scalene_parseargs.py`)\n\n```python\nclass RichArgParser(argparse.ArgumentParser):\n    \"\"\"ArgumentParser that uses Rich for colored output on Python < 3.14.\"\"\"\n\n    def __init__(self, *args, **kwargs):\n        if sys.version_info < (3, 14):\n            from rich.console import Console\n            self._console = Console()\n        else:\n            self._console = None\n        super().__init__(*args, **kwargs)\n```\n\nThe `_colorize_help_for_rich()` function applies Python 3.14-style colors using Rich markup:\n- `usage:` and `options:` → bold blue\n- Program name → bold magenta\n- Long options (`--foo`) → bold cyan\n- Short options (`-h`) → bold green\n- Metavars (`FOO`) → bold yellow\n\n### GUI Patterns\n\n**Preventing Browser Password Prompts:**\nUse `autocomplete=\"one-time-code\"` on password/API key inputs to prevent browsers from offering to save them:\n```html\n<input type=\"password\" id=\"api-key\" autocomplete=\"one-time-code\">\n```\n\n**Show/Hide Password Toggle:**\n```typescript\nfunction togglePassword(inputId: string, button: HTMLButtonElement): void {\n  const input = document.getElementById(inputId) as HTMLInputElement;\n  if (input.type === \"password\") {\n    input.type = \"text\";\n    button.textContent = \"Hide\";\n  } else {\n    input.type = \"password\";\n    button.textContent = \"Show\";\n  }\n}\n```\n\n**Provider Field Visibility:**\nUse CSS classes to show/hide provider-specific fields:\n```typescript\nfunction toggleServiceFields(): void {\n  const service = (document.getElementById(\"service\") as HTMLSelectElement).value;\n  // Hide all provider sections\n  document.querySelectorAll(\".provider-section\").forEach((el) => {\n    (el as HTMLElement).style.display = \"none\";\n  });\n  // Show selected provider section\n  const section = document.querySelector(`.${service}-fields`);\n  if (section) (section as HTMLElement).style.display = \"block\";\n}\n```\n\n**Persistent Form Elements:**\nAdd class `persistent` to inputs that should be saved/restored from localStorage:\n```html\n<input type=\"text\" id=\"api-key\" class=\"persistent\">\n```\nThe `persistence.ts` module handles save/restore automatically.\n\n**Standalone HTML Generation:**\nThe `generate_html()` function in `scalene_utility.py` supports a `standalone` parameter:\n- When `standalone=False` (default): Assets are referenced as local files (e.g., `<script src=\"jquery-3.6.0.slim.min.js\">`)\n- When `standalone=True`: All assets are embedded inline (JS/CSS as text, images as base64)\n\nThe Jinja2 template uses conditionals:\n```html\n{% if standalone %}\n<script>{{ jquery_js }}</script>\n<style>{{ bootstrap_css }}</style>\n{% else %}\n<script src=\"jquery-3.6.0.slim.min.js\"></script>\n<link href=\"bootstrap.min.css\" rel=\"stylesheet\">\n{% endif %}\n```\n\n### Module Imports\n\nWhen importing submodules, be explicit:\n\n```python\n# Correct - mypy can verify this\nimport importlib.util\nimportlib.util.find_spec(mod_name)\n\n# Wrong - mypy error: Module has no attribute \"util\"\nimport importlib\nimportlib.util.find_spec(mod_name)\n```\n\n## Testing\n\n### Test Files (`tests/`)\n\n- **`test_coverup_*.py`** - Auto-generated coverage tests\n- **`test_runningstats.py`** - Statistics tests (requires `hypothesis`)\n- **`test_scalene_json.py`** - JSON output tests (requires `hypothesis`)\n- **`test_nested_package_relative_import.py`** - Import handling tests\n\n### Test Dependencies\n\n```bash\npip install pytest pytest-asyncio hypothesis\n```\n\n### Running Tests Across Python Versions\n\n```bash\nfor v in 3.9 3.10 3.11 3.12 3.13 3.14; do\n    python$v -m pytest tests/test_coverup_83.py -v\ndone\n```\n\n### Flaky Smoketests\n\nThe smoketests in `test/` can be flaky due to timing/sampling issues inherent to profiling:\n\n- **\"No non-zero lines in X\"** - The profiler didn't collect enough samples. This happens when the test runs too quickly or signal delivery timing varies.\n- **\"Expected function 'X' not returned\"** - A function wasn't sampled. Common with short-running functions.\n\nThese failures are usually timing-related and pass on re-run. They're more common on CI due to variable machine load.\n\n### Port Binding in Tests\n\nWhen testing port availability, never use hardcoded ports - they may already be in use on CI runners:\n\n```python\n# Bad - port 49200 might be in use\nport = 49200\nsock.bind((\"\", port))\n\n# Good - find an available port first\nport = find_available_port(49200, 49300)\nif port is None:\n    return  # Skip test if no ports available\nsock.bind((\"\", port))\n```\n\n## CI/CD (`.github/workflows/`)\n\n- **`run-linters.yml`** - Runs mypy and ruff on Python 3.9-3.14\n- **`tests.yml`** - Runs pytest on Python 3.9-3.14\n- **`build-and-upload.yml`** - Build and publish to PyPI\n\n## Common Tasks\n\n### Adding a New CLI Option\n\n1. Add default value in `scalene_arguments.py`:\n   ```python\n   class ScaleneArgumentsDict(TypedDict, total=False):\n       my_option: bool\n   ```\n\n2. Add argument in `scalene_parseargs.py`:\n   ```python\n   parser.add_argument(\n       \"--my-option\",\n       dest=\"my_option\",\n       action=\"store_true\",\n       default=defaults.my_option,\n       help=\"Description of option\",\n   )\n   ```\n\n### Adding a New AI Provider\n\n1. **Create provider module** (`scalene/scalene-gui/newprovider.ts`):\n   ```typescript\n   export async function sendPromptToNewProvider(\n     prompt: string,\n     apiKey: string\n   ): Promise<string> {\n     // API call implementation\n   }\n\n   export async function fetchNewProviderModels(apiKey: string): Promise<string[]> {\n     // Optional: fetch available models from API\n   }\n   ```\n\n2. **Update `optimizations.ts`**:\n   - Import the new module\n   - Add case in `sendPromptToService()` switch statement\n\n3. **Update `index.html.template`**:\n   - Add option to `#service` select dropdown\n   - Add provider section with API key input, model selector, etc.\n   - Add CSS for `.newprovider-fields` visibility\n\n4. **Update `scalene-gui.ts`**:\n   - Add provider to `toggleServiceFields()` function\n   - Add refresh handler if dynamic model fetching is supported\n   - Update `getDefaultProvider()` if env var support is needed\n\n5. **Update `persistence.ts`** (for env var support):\n   - Add mapping in `envKeyMap` for new fields\n\n6. **Update `scalene_utility.py`**:\n   - Read environment variable in `api_keys` dict\n   - Pass to template rendering\n\n7. **Rebuild the bundle**:\n   ```bash\n   cd scalene/scalene-gui\n   npx esbuild scalene-gui.ts --bundle --outfile=scalene-gui-bundle.js --format=iife --global-name=ScaleneGUI\n   ```\n\n### Environment Variable API Keys\n\nThe GUI supports prepopulating API keys from environment variables:\n\n| Element ID | Environment Variable | Provider |\n|------------|---------------------|----------|\n| `api-key` | `OPENAI_API_KEY` | OpenAI |\n| `anthropic-api-key` | `ANTHROPIC_API_KEY` | Anthropic |\n| `gemini-api-key` | `GEMINI_API_KEY` or `GOOGLE_API_KEY` | Gemini |\n| `azure-api-key` | `AZURE_OPENAI_API_KEY` | Azure OpenAI |\n| `azure-api-url` | `AZURE_OPENAI_ENDPOINT` | Azure OpenAI |\n| `aws-access-key` | `AWS_ACCESS_KEY_ID` | Amazon Bedrock |\n| `aws-secret-key` | `AWS_SECRET_ACCESS_KEY` | Amazon Bedrock |\n| `aws-region` | `AWS_DEFAULT_REGION` or `AWS_REGION` | Amazon Bedrock |\n\n**Flow:**\n1. `scalene_utility.py` reads env vars and passes to Jinja2 template\n2. Template injects `envApiKeys` JavaScript object into page\n3. `persistence.ts` uses env vars as fallbacks when localStorage is empty\n\n### Updating Version\n\nEdit `scalene/scalene_config.py`:\n```python\nscalene_version = \"X.Y.Z\"\nscalene_date = \"YYYY.MM.DD\"\n```\n\n## Dependencies\n\nKey runtime dependencies:\n- `rich` - Terminal formatting and colors\n- `cloudpickle` - Serialization\n- `pynvml` - NVIDIA GPU support (optional)\n\nSee `requirements.txt` for full list.\n\n## CLI Structure\n\nScalene uses a verb-based CLI with two main subcommands:\n\n```bash\n# Profile a program (saves to scalene-profile.json by default)\nscalene run [options] yourprogram.py\n\n# View an existing profile\nscalene view [options] [profile.json]\n```\n\n### Run Subcommand Options\n\n```bash\nscalene run prog.py                      # profile, save to scalene-profile.json\nscalene run -o my.json prog.py           # save to custom file\nscalene run --cpu-only prog.py           # profile CPU only (faster)\nscalene run -c config.yaml prog.py       # load options from config file\nscalene run prog.py --- --arg            # pass args to program\n```\n\n### View Subcommand Options\n\n```bash\nscalene view                             # open in browser\nscalene view --cli                       # view in terminal\nscalene view --html                      # save to scalene-profile.html\nscalene view --standalone                # save as self-contained HTML (all assets embedded)\nscalene view myprofile.json              # open specific profile\n```\n\n### Profile Completion Message\n\nAfter profiling completes, Scalene prints instructions for viewing the profile:\n```\nScalene: profile saved to scalene-profile.json\n  To view in browser:  scalene view\n  To view in terminal: scalene view --cli\n```\n\nThe filename is only included in the command if a non-default output file was used.\n\n### YAML Configuration\n\nCreate a `scalene.yaml` file with options:\n\n```yaml\noutfile: my-profile.json\ncpu-only: true\nprofile-only: \"mypackage,utils\"\ncpu-percent-threshold: 5\n```\n\nLoad with: `scalene run -c scalene.yaml prog.py`\n\n### Advanced Options\n\nUse `scalene run --help-advanced` to see all options including:\n- `--profile-all` - profile all code, not just the target program\n- `--profile-only PATH` - only profile files containing these strings\n- `--profile-exclude PATH` - exclude files containing these strings\n- `--profile-system-libraries` - profile Python stdlib and installed packages (skipped by default)\n- `--gpu` - profile GPU time and memory\n- `--memory` - profile memory usage\n- `--stacks` - collect stack traces\n- `--profile-interval N` - output profiles every N seconds\n\n### Smoke Tests\n\nSmoke tests in `test/` use the new CLI syntax:\n\n```python\n# test/smoketest.py\ncmd = [sys.executable, \"-m\", \"scalene\", \"run\", \"-o\", str(outfile), *rest, fname]\n```\n\n### GitHub Workflows\n\nWorkflows in `.github/workflows/` use the new CLI:\n\n```yaml\n# Profile with interval, then view\n- run: python -m scalene run --profile-interval=2 test/testme.py && python -m scalene view --cli\n\n# Profile with module invocation\n- run: python -m scalene run --- -m import_stress_test && python -m scalene view --cli\n```\n\n## Signal Handling\n\nScalene uses several Unix signals for profiling. The signal assignments are in `scalene_signals.py`:\n\n| Signal | Purpose | Platform |\n|--------|---------|----------|\n| `SIGVTALRM` | CPU profiling timer (default) | Unix |\n| `SIGALRM` | CPU profiling timer (real time mode) | Unix |\n| `SIGILL` | Start profiling (`--on`) | Unix |\n| `SIGBUS` | Stop profiling (`--off`) | Unix |\n| `SIGPROF` | memcpy tracking | Unix |\n| `SIGXCPU` | malloc tracking | Unix |\n| `SIGXFSZ` | free tracking | Unix |\n\n### Signal Conflicts with Libraries\n\nLibraries like PyTorch Lightning may also use these signals. The `replacement_signal_fns.py` module handles conflicts:\n\n**On Linux:** Uses real-time signals (`SIGRTMIN+1` to `SIGRTMIN+5`) for redirection. When user code sets a handler for a Scalene signal, their handler is redirected to a real-time signal. Calls to `raise_signal()` and `kill()` are also redirected transparently.\n\n**On macOS/other platforms:** Uses handler chaining. Both Scalene's handler and the user's handler are called when the signal fires.\n\n```python\n# Platform-specific signal handling\n_use_rt_signals = sys.platform == \"linux\" and hasattr(signal, \"SIGRTMIN\")\n\nif _use_rt_signals:\n    # Linux: redirect to real-time signals\n    rt_base = signal.SIGRTMIN + 1\n    _signal_redirects[signal.SIGILL] = rt_base\nelse:\n    # macOS: chain handlers\n    def chained_handler(sig, frame):\n        scalene_handler(sig, frame)\n        user_handler(sig, frame)\n```\n\n### Frame Line Number Can Be None (Python 3.11+)\n\nIn Python 3.11+, `frame.f_lineno` can be `None` in edge cases (e.g., during multiprocessing cleanup). Always use a fallback:\n\n```python\nlineno = frame.f_lineno if frame.f_lineno is not None else frame.f_code.co_firstlineno\n```\n\n## Native Extension Build Issues\n\n### C++ Standard Library Conflicts with vendor/printf\n\nThe `vendor/printf/printf.h` header defines macros that conflict with C++ standard library:\n\n```c\n#define vsnprintf vsnprintf_\n#define snprintf  snprintf_\n```\n\nThis breaks `std::vsnprintf` in `<string>` and other headers. **Fix:** Include C++ standard headers BEFORE vendor headers in `src/source/libscalene.cpp`:\n\n```cpp\n// Include C++ standard headers FIRST\n#include <cstddef>\n#include <string>\n\n// Then vendor headers that define conflicting macros\n#include <heaplayers.h>  // Eventually includes printf.h\n```\n\n## Profiling Guide\n\nSee [Scalene-Agents.md](Scalene-Agents.md) for detailed information about interpreting Scalene's profiling output, including Python vs C time, memory metrics, and optimization strategies.\n\n## Debugging Guide\n\nSee [Scalene-Debugging.md](Scalene-Debugging.md) for signal handler debugging, async profiling debugging, the profile output pipeline (three separate renderers!), and unbounded growth prevention patterns.\n\n## GUI Development Guide\n\nSee [Scalene-GUI.md](Scalene-GUI.md) for adding new columns, Vega-Lite chart types, pie chart best practices (two-wedge rendering, rotating pies), and the chart rendering flow.\n"

It runs orders of magnitude faster than many other\nprofilers while delivering far more detailed information. It is also\nthe first profiler ever to incorporate AI-powered proposed\noptimizations.\n\n### AI-powered optimization suggestions\n\n> **Note**\n>\n> For optimization suggestions, Scalene supports a variety of AI providers, including [Amazon Bedrock](https://aws.amazon.com/bedrock), [Microsoft Azure](https://azure.microsoft.com/en-us/), [OpenAI](https://openai.com), and local models via [Ollama](https://ollama.com/). To enable AI-powered optimization suggestions from AI providers, you need to select a provider and, if needed, enter your credentials, in the box under \"AI Optimization Options\".\n>\n> <img width=\"607\" height=\"316\" alt=\"AI Optimization Options\" src=\"https://github.com/user-attachments/assets/3c803237-063f-481a-8624-5c1d7f205c8a\" />\n\n\nOnce you've entered your key and any other needed data, click on the lightning bolt (⚡) beside any line or the explosion (💥) for an entire region of code to generate a proposed optimization. Click on a proposed optimization to copy it to the clipboard.\n\n<img width=\"571\" alt=\"example proposed optimization\" src=\"https://user-images.githubusercontent.com/1612723/211639968-37cf793f-3290-43d1-9282-79e579558388.png\">\n\nYou can click as many times as you like on the lightning bolt or explosion, and it will generate different suggested optimizations. Your mileage may vary, but in some cases, the suggestions are quite impressive (e.g., order-of-magnitude improvements). \n  \n### Quick Start\n\n#### Installing Scalene:\n\n```console\npython3 -m pip install -U scalene\n```\n\nor\n\n```console\nconda install -c conda-forge scalene\n```\n\n#### Using Scalene:\n\nAfter installing Scalene, you can use Scalene at the command line, or as a Visual Studio Code extension.\n\n<details>\n  <summary>\n    Using the Scalene VS Code Extension:\n  </summary>\n  \n\nFirst, install <a href=\"https://marketplace.visualstudio.com/items?itemName=EmeryBerger.scalene\">the Scalene extension from the VS Code Marketplace</a> or by searching for it within VS Code by typing Command-Shift-X (Mac) or Ctrl-Shift-X (Windows).

Hover over bars to see breakdowns of CPU and memory\nconsumption, and click on underlined column headers to sort the\ncolumns. The GUI works fully offline with no internet connection required.\n\nUse `scalene view --standalone` to generate a completely self-contained HTML file with all assets embedded, perfect for sharing or archiving.\n\n[![Scalene web GUI](https://raw.githubusercontent.com/plasma-umass/scalene/master/docs/scalene-gui-example.png)](https://raw.githubusercontent.com/plasma-umass/scalene/master/docs/scalene-gui-example-full.png)\n\n\n## Scalene Overview\n\n### Scalene talk (PyCon US 2021)\n\n[This talk](https://youtu.be/5iEf-_7mM1k) presented at PyCon 2021 walks through Scalene's advantages and how to use it to debug the performance of an application (and provides some technical details on its internals). We highly recommend watching this video!\n\n[![Scalene presentation at PyCon 2021](https://raw.githubusercontent.com/plasma-umass/scalene/master/docs/images/scalene-video-img.png)](https://youtu.be/5iEf-_7mM1k \"Scalene presentation at PyCon 2021\")\n\n### Fast and Accurate\n\n- Scalene is **_fast_**. It uses sampling instead of instrumentation or relying on Python's tracing facilities. Its overhead is typically no more than 10-20% (and often less).\n\n- Scalene is **accurate**. We tested CPU profiler accuracy and found that Scalene is among the most accurate profilers, correctly measuring time taken.\n\n![Profiler accuracy](https://github.com/plasma-umass/scalene/raw/master/docs/cpu-accuracy-comparison.png)\n\n- Scalene performs profiling **_at the line level_** _and_ **_per function_**, pointing to the functions and the specific lines of code responsible for the execution time in your program.\n\n### CPU profiling\n\n- Scalene **separates out time spent in Python from time in native code** (including libraries). Most Python programmers aren't going to optimize the performance of native code (which is usually either in the Python implementation or external libraries), so this helps developers focus their optimization efforts on the code they can actually improve.\n- Scalene **highlights hotspots** (code accounting for significant percentages of CPU time or memory allocation) in red, making them even easier to spot.\n- Scalene also separates out **system time**, making it easy to find I/O bottlenecks.\n\n### GPU profiling\n\n- Scalene reports **GPU time** (currently limited to NVIDIA-based systems).\n\n### Memory profiling\n\n- Scalene **profiles memory usage**. In addition to tracking CPU usage, Scalene also points to the specific lines of code responsible for memory growth. It accomplishes this via an included specialized memory allocator.\n- Scalene separates out the percentage of **memory consumed by Python code vs. native code**.\n- Scalene produces **_per-line_ memory profiles**.\n- Scalene **identifies lines with likely memory leaks**.\n- Scalene **profiles _copying volume_**, making it easy to spot inadvertent copying, especially due to crossing Python/library boundaries (e.g., accidentally converting `numpy` arrays into Python arrays, and vice versa).\n\n### Other features\n\n- Scalene can produce **reduced profiles** (via `--reduced-profile`) that only report lines that consume more than 1% of CPU or perform at least 100 allocations.\n- Scalene supports `@profile` decorators to profile only specific functions.\n- When Scalene is profiling a program launched in the background (via `&`), you can **suspend and resume profiling**.\n\n# Comparison to Other Profilers\n\n## Performance and Features\n\nBelow is a table comparing the **performance and features** of various profilers to Scalene.\n\n![Performance and feature comparison](https://raw.githubusercontent.com/plasma-umass/scalene/master/docs/images/profiler-comparison.png)\n\n- **Slowdown**: the slowdown when running a benchmark from the Pyperformance suite. Green means less than 2x overhead. Scalene's overhead is just a 35% slowdown.\n\nScalene has all of the following features, many of which only Scalene supports:\n\n- **Lines or functions**: does the profiler report information only for entire functions, or for every line -- Scalene does both.\n- **Unmodified Code**: works on unmodified code.\n- **Threads**: supports Python threads.\n- **Multiprocessing**: supports use of the `multiprocessing` library -- _Scalene only_\n- **Python vs. C time**: breaks out time spent in Python vs. native code (e.g., libraries) -- _Scalene only_\n- **System time**: breaks out system time (e.g., sleeping or performing I/O) -- _Scalene only_\n- **Profiles memory**: reports memory consumption per line / function\n- **GPU**: reports time spent on an NVIDIA GPU (if present) -- _Scalene only_\n- **Memory trends**: reports memory use over time per line / function -- _Scalene only_\n- **Copy volume**: reports megabytes being copied per second -- _Scalene only_\n- **Detects leaks**: automatically pinpoints lines responsible for likely memory leaks -- _Scalene only_\n\n## Output\n\nIf you include the `--cli` option, Scalene prints annotated source code for the program being profiled\n(as text, JSON (`--json`), or HTML (`--html`)) and any modules it\nuses in the same directory or subdirectories (you can optionally have\nit `--profile-all` and only include files with at least a\n`--cpu-percent-threshold` of time).  Here is a snippet from\n`pystone.py`.\n\n![Example profile](https://raw.githubusercontent.com/plasma-umass/scalene/master/docs/images/sample-profile-pystone.png)\n\n* **Memory usage at the top**: Visualized by \"sparklines\", memory consumption over the runtime of the profiled code.\n* **\"Time Python\"**: How much time was spent in Python code.\n* **\"native\"**: How much time was spent in non-Python code (e.g., libraries written in C/C++).\n* **\"system\"**: How much time was spent in the system (e.g., I/O).\n* **\"GPU\"**: (not shown here) How much time spent on the GPU, if your system has an NVIDIA GPU installed.\n* **\"Memory Python\"**: How much of the memory allocation happened on the Python side of the code, as opposed to in non-Python code (e.g., libraries written in C/C++).\n* **\"net\"**: Positive net memory numbers indicate total memory allocation in megabytes; negative net memory numbers indicate memory reclamation.\n* **\"timeline / %\"**: Visualized by \"sparklines\", memory consumption generated by this line over the program runtime, and the percentages of total memory activity this line represents.\n* **\"Copy (MB/s)\"**: The amount of megabytes being copied per second (see \"About Scalene\").\n\n##  Scalene\n\nThe following command runs Scalene on a provided example program.\n\n```console\nscalene test/testme.py\n```\n\n<details>\n <summary>\n  Click to see all Scalene's options (available by running with <code>--help</code>)\n </summary>\n\n```console\n% scalene --help\nScalene: a high-precision CPU and memory profiler, version 1.5.51 (2025.01.29)\nhttps://github.com/plasma-umass/scalene\n\ncommands:\n  run     Profile a Python program (saves to scalene-profile.json)\n  view    View an existing profile in browser or terminal\n\nexamples:\n  % scalene run your_program.py              #

You can run it as follows (for example):\n\n`scalene run -m pytest your_test.py`\n\nor\n\n`python3 -m scalene run -m pytest your_test.py` \n\n</details>\n\n<details>\n<summary>\nIs there any way to get shorter profiles or do more targeted profiling?\n</summary>\n\n**A:** Yes! There are several options:\n\n1. Use `--reduced-profile` to include only lines and files with memory/CPU/GPU activity.\n2. Use `--profile-only` to include only filenames containing specific strings (as in, `--profile-only foo,bar,baz`).\n3. Decorate functions of interest with `@profile` to have Scalene report _only_ those functions.\n4. Turn profiling on and off programmatically by importing Scalene profiler (`from scalene import scalene_profiler`) and then turning profiling on and off via `scalene_profiler.start()` and `scalene_profiler.stop()`. By default, Scalene runs with profiling on, so to delay profiling until desired, use the `--off` command-line option (`scalene run --off yourprogram.py`).\n</details>\n\n<details>\n<summary>\nHow do I run Scalene in PyCharm?\n</summary>\n\n**A:**  In PyCharm, you can run Scalene at the command line by opening the terminal at the bottom of the IDE and running a Scalene command (e.g., `scalene run <your program>`). Then use `scalene view --html` to generate an HTML file (`scalene-profile.html`) that you can view in the IDE.\n</details>\n\n<details>\n<summary>\nHow do I use Scalene with Django?\n</summary>\n\n**A:** Pass in the `--noreload` option (see https://github.com/plasma-umass/scalene/issues/178).\n</details>\n\n\n<details>\n<summary>\nDoes Scalene work with gevent/Greenlets?\n</summary>\n\n**A:** Yes!

    "content": "# Scalene Profiling Guide\n\n## Basic Usage\n\n```bash\npython3 -m scalene --cli --json --outfile profile.json script.py\n```\n\n## Understanding Python vs C (Native) Time\n\nScalene's key differentiator is separating Python time from C/native time:\n\n- **`n_cpu_percent_python`**: Time spent executing Python bytecode - **this is your optimization target**\n- **`n_cpu_percent_c`**: Time spent in C extensions/native code - generally NOT optimizable at the Python level\n\n**Critical insight**: Focus optimization efforts on code with high Python time. Code spending most of its time in C is already running native code and can only be improved by:\n1. Reducing the number of calls to the C code (algorithmic changes)\n2. Using the library more efficiently (e.g., batching operations)\n3. Switching to a different library\n\nFor example, Python's slice reversal `perm[:k+1] = perm[k::-1]` shows high C time because it's implemented in C. Replacing it with a Python loop makes performance *worse* because it moves work from fast C code to slow Python code.\n\n## Memory Profiling Metrics\n\nScalene tracks detailed memory behavior:\n\n- **`n_malloc_mb`**: Memory allocated on this line\n- **`n_peak_mb`**: Peak memory usage attributed to this line\n- **`n_avg_mb`**: Average memory footprint\n- **`n_growth_mb`**: Net memory growth (allocations minus frees) - useful for detecting memory leaks\n- **`n_usage_fraction`**: Fraction of total memory used by this line\n\n**When to focus on memory**:\n- High `n_growth_mb` with `n_python_fraction` near 1.0 indicates Python objects accumulating (potential leak)\n- High `n_peak_mb` suggests opportunities to reduce memory footprint by processing data in chunks\n\n## Copy Volume Tracking\n\n- **`n_copy_mb_s`**: Rate of memory copying in MB/s attributed to this line\n\n**Why this matters**: High copy volume indicates inefficient data handling:\n- Unnecessary string concatenation in loops (use `join()` or `io.StringIO`)\n- Repeated array/list copies (use views, in-place operations, or pre-allocation)\n- Passing large objects by value when references would suffice\n\nExample: A line showing 100+ MB/s copy volume in a data processing loop suggests refactoring to avoid intermediate copies.\n\n## GPU Metrics (if applicable)\n\n- **`n_gpu_percent`**: Percentage of GPU time\n- **`n_gpu_avg_memory_mb`**: Average GPU memory usage\n- **`n_gpu_peak_memory_mb`**: Peak GPU memory usage\n\n## System Time\n\n- **`n_sys_percent`**: Time spent in system calls (I/O, etc.)\n\nHigh system time may indicate:\n- Excessive file I/O (batch reads/writes)\n- Too many small network requests (batch API calls)\n- Suboptimal disk access patterns\n\n## Optimization Decision Tree\n\n1. **Check Python vs C time split**\n   - High Python time → Optimize the Python code\n   - High C time → Consider algorithmic changes or different libraries\n\n2. **Check memory growth**\n   - Sustained growth → Look for leaks, unbounded caches, or accumulating data structures\n\n3. **Check copy volume**\n   - High copy rate → Refactor to use views, in-place operations, or pre-allocation\n\n4. **Check system time**\n   - High system time → Batch I/O operations, use async I/O, or optimize file access patterns\n"

    "content": "# Debugging Patterns for Scalene\n\n## Signal Handler Debugging\n\nThe CPU signal handler (`cpu_signal_handler`) receives `this_frame` as the raw frame parameter. The `compute_frames_to_record()` function filters this down to user-only frames via `_should_trace()`.\n\n**Critical gotcha**: When the main thread is idle in the event loop (the exact case async profiling needs to detect), there are NO user frames — asyncio/selector frames are all filtered out. So `frames` from `compute_frames_to_record()` is empty. Must use `this_frame` directly for event loop detection.\n\n## Async Profiling Debugging\n\nTo verify async profiling is working:\n1. Create a test program with known behavior (fast I/O, slow I/O, CPU-bound)\n2. Profile: `python3 -m scalene run --async test/test_async_demo.py`\n3. Check JSON: `python3 -m scalene view --cli` should show Await % column\n4. Verify proportions: slow_io >> mixed_work >> fast_io, cpu_work = 0% await\n\nTo debug zero-await-data:\n- Check `is_in_event_loop()` returns True when event loop is idle\n- Check `_poll_suspended_tasks()` finds tasks\n- Verify the signal handler is using `this_frame`, not filtered `frames`\n\n## Profile Output Pipeline\n\nThere are **three separate renderers** for profile output. All must be updated when adding new columns:\n\n- **JSON output**: `scalene_json.py:output_profiles()` → `output_profile_line()`\n- **CLI viewer**: `scalene_parseargs.py:_display_profile_cli()` — used by `scalene view --cli`\n- **HTML/GUI output**: `scalene_output.py:output_profiles()` — used by `scalene view --html`\n- **GUI (browser)**: `scalene-gui.ts:makeProfileLine()` → embedded Vega-Lite charts via `vegaEmbed()`\n- **Standalone HTML**: `scalene_utility.py:generate_html(standalone=True)` embeds all assets inline\n\nNote: `_display_profile_cli()` in `scalene_parseargs.py` is completely separate from `scalene_output.py`. This is easy to miss.\n\n## Unbounded Growth Prevention\n\nAny dict or set that accumulates per-sample data must be bounded:\n\n- **Dicts keyed by (filename, lineno)**: Inherently bounded by source code size — OK.\n- **Sets of names/strings**: Must be capped (e.g., `async_task_names` capped at 100 per location).\n- **Tracking dicts** (e.g., `_suspended_tasks`): Must be capped and cleared when exceeded.\n- **`RunningStats`**: Fixed-size (count, mean, M2) — OK.\n- **`ScaleneSigQueue`**: Uses `SimpleQueue` with continuous consumer drain — OK.\n"

    "content": "# GUI Development Patterns\n\n## Adding a New Column\n\n1. **`gui-elements.ts`**: Add chart function (e.g., `makeAwaitPie`) following existing patterns\n2. **`scalene-gui.ts`**:\n   - Add to imports\n   - Add chart array (e.g., `const await_pies: (unknown | null)[] = []`)\n   - Add column in `makeTableHeader()`\n   - Add cell rendering in `makeProfileLine()` — push chart specs to array\n   - Pass array through both call sites (line profile loop + function profile loop)\n   - Add `embedCharts(await_pies, \"await_pie\")` at the end\n3. **Rebuild**: `npx esbuild scalene-gui.ts --bundle --outfile=scalene-gui-bundle.js --format=iife --global-name=ScaleneGUI`\n4. **`scalene_json.py`**: Add field to `FunctionDetail`, compute in payload\n5. **`scalene_output.py`**: Add column for CLI `--html` output\n6. **`scalene_parseargs.py`**: Add column in `_display_profile_cli()` for `scalene view --cli`\n\n## Chart Types (Vega-Lite)\n\nAll charts are Vega-Lite specs rendered via `vegaEmbed()` after DOM insertion.\n\n- **Bar**: `makeBar()` — stacked horizontal bar (CPU time: Python/native/system)\n- **Pie**: `makeGPUPie()`, `makeAwaitPie()`, `makeMemoryPie()` — arc charts\n- **Sparkline**: `makeSparkline()` — line chart for memory timeline\n- **NRT/NC bars**: `makeNRTBar()`, `makeNCTimeBar()` — Neuron time bars\n- **Standard dimensions**: 20px height, various widths\n\n## Pie Chart Best Practices\n\n- Always use **two data values** (filled + remaining) for a complete circle. Single-value pies with `scale: { domain: [0, 100] }` show partial arcs with gaps — looks bad.\n- For **rotating pies** (each row's wedge starts where previous ended): use `scale: { range: [startAngle, startAngle + 2*PI] }` on the theta encoding. Track cumulative angle:\n  ```typescript\n  pieAngles.await += (pct / 100) * 2 * Math.PI;\n  ```\n- Reset angle state per table (line profile and function profile tables get separate `pieAngles` objects).\n\n## Chart Rendering Flow\n\n1. `makeProfileLine()` builds HTML string with `<span id=\"chart_name${index}\">` placeholders\n2. Chart specs are pushed to arrays (e.g., `cpu_bars`, `gpu_pies`, `await_pies`)\n3. After all HTML is inserted into DOM, `embedCharts(array, \"prefix\")` calls `vegaEmbed()` for each spec\n4. SVGs render asynchronously — Selenium tests need explicit waits to verify SVG content\n\n## makeProfileLine Call Sites\n\nThis function has many parameters. When adding new ones, append to the end with defaults. The two call sites are:\n- Line profile loop: creates `linePieAngles = { await: 0, gpu: 0 }` before the loop\n- Function profile loop: creates `fnPieAngles = { await: 0, gpu: 0 }` before the loop\n"

    "content": "# Windows Memory Profiling Port - Progress and Plans\n\n## Overview\n\nPorting Scalene's memory profiling from Linux/macOS to Windows. On Unix systems, Scalene uses `LD_PRELOAD`/`DYLD_INSERT_LIBRARIES` to interpose on malloc/free. Windows doesn't support this mechanism, so we use Python's allocator API instead.\n\n## Architecture\n\n### Unix Approach\n- `libscalene.so`/`libscalene.dylib` is preloaded via environment variables\n- Interposes on malloc/free/realloc at the C library level\n- Uses Unix signals (SIGXCPU, SIGXFSZ) to communicate with Python\n- Uses POSIX shared memory (`/tmp/scalene-*`) for data transfer\n\n### Windows Approach\n- `libscalene.dll` is loaded explicitly via ctypes\n- Uses Python's `PyMem_SetAllocator` API to intercept allocations\n- Uses Windows Events instead of Unix signals (but currently using polling)\n- Uses Windows Named Shared Memory (`Local\\scalene-*`) for data transfer\n\n## Files Created/Modified\n\n### New Files\n- `src/source/libscalene_windows.cpp` - Main Windows DLL implementation (includes Detours native hooks)\n- `src/include/samplefile_win.hpp` - Windows shared memory implementation\n- `src/include/common_win.hpp` - Windows compatibility macros\n- `src/include/mallocrecursionguard_win.hpp` - Windows TLS-based recursion guard\n- `scalene/scalene_windows.py` - Python helper for Windows memory profiling\n- `vendor/Detours/` - Microsoft Detours library for native malloc/free hooking (vendored)\n\n### Modified Files\n- `CMakeLists.txt` - Cross-platform build configuration with Detours integration\n- `src/include/pywhere.hpp` - Windows DLL export/import macros\n- `src/source/pywhere.cpp` - Windows symbol lookup via accessor functions\n- `scalene/scalene_profiler.py` - Windows DLL loading and initialization\n- `scalene/scalene_mapfile.py` - Windows named shared memory support\n- `scalene/scalene_signal_manager.py` - Windows memory polling thread\n- `scalene/scalene_preload.py` - Case-insensitive ARM64 detection\n- `scalene/scalene_arguments.py` - Enable memory profiling on Windows\n\n## Current Status (2024-12-17) - FULLY WORKING WITH NATIVE LIBRARY SUPPORT!\n\n### All Core Features Working\n1. ✅ DLL builds successfully with CMake/MSBuild for ARM64\n2. ✅ DLL loads without crashing\n3. ✅ Python allocator hooks are installed via `PyMem_SetAllocator`\n4. ✅ Allocation size tracking implemented (hash map with critical section)\n5. ✅ Shared memory objects created successfully (both malloc and memcpy)\n6. ✅ ScaleneMapFile opens shared memory from Python side successfully\n7. ✅ All `thread_local` variables removed (caused crashes with dynamically loaded DLLs on Windows)\n8. ✅ Data format updated to match Unix (comma-separated, 9 fields for malloc, 6 for memcpy)\n9. ✅ Windows memory polling thread added to `scalene_signal_manager.py`\n10. ✅ **64-bit pointer handling fixed in ctypes code**\n11. ✅ Memory profiling working - samples being collected and logged\n12. ✅ **Native library tracking (numpy, etc.) via Microsoft Detours**\n13. ✅ **Proper free tracking with manual size tracking hash map**\n\n### Test Results (2024-12-17)\n```\nalloc_samples: 203\nmax_footprint_mb: 152.71\nmax_footprint_python_fraction: 0.000288\nNative fraction: 99.97%\n```\n\nThe profiler now correctly tracks memory allocations from native libraries like numpy, with proper line attribution.\n\n### Known Limitation\n- Console output may fail with `UnicodeEncodeError` on Windows consoles using CP1252 encoding\n- This is not a profiler bug - it's a Windows console limitation\n- **Workaround**: Set `PYTHONIOENCODING=utf-8` environment variable or use `--html` or `--json` output\n\n## The Critical Bug Fix (2024-12-16)\n\n### Root Cause: ctypes 64-bit Pointer Truncation\n\nThe Access Violation crash (exit code 3221225477 = 0xC0000005) was caused by a **ctypes bug** where 64-bit pointers were being truncated to 32-bit values.\n\n**Problem**: By default, ctypes assumes Windows API functions return `c_int` (32-bit). On 64-bit Windows, `MapViewOfFile` returns a 64-bit pointer. Without explicit return type declaration, the high 32 bits were truncated, causing invalid memory addresses.\n\n**Example of bug**:\n```\nMapViewOfFile returns: 0x00007FFBF2650B90  (valid 64-bit pointer)\nctypes stored as:      0x00000000F2650B90  (truncated to 32-bit, invalid!)\n```\n\n### The Fix (scalene_mapfile.py)\n\nAdded proper return type declarations before calling Windows API functions:\n\n```python\nfrom ctypes import wintypes\n\nkernel32 = ctypes.windll.kernel32\n\n# IMPORTANT: Set proper return types for Windows API functions\n# Default ctypes return type is c_int (32-bit) which truncates 64-bit pointers\nkernel32.OpenFileMappingW.restype = wintypes.HANDLE\nkernel32.MapViewOfFile.restype = ctypes.c_void_p\nkernel32.UnmapViewOfFile.argtypes = [ctypes.c_void_p]\nkernel32.CloseHandle.argtypes = [wintypes.HANDLE]\n```\n\nThis fix is in `scalene/scalene_mapfile.py` in the `_init_windows()` method.\n\n## Native Library Memory Tracking (2024-12-17)\n\n### The Problem\n\nThe original Windows implementation only tracked Python allocations via `PyMem_SetAllocator`. Native library allocations (numpy arrays, pandas dataframes, etc.) went untracked because they bypass Python's allocator and call the C runtime `malloc`/`free` directly.\n\n**Before**: Only Python allocations tracked (0.03% of actual memory usage)\n**After**: All allocations tracked including native libraries (99.97% native, 0.03% Python)\n\n### Solution: Microsoft Detours\n\nWe use [Microsoft Detours](https://github.com/microsoft/Detours) to intercept `malloc`/`free`/`realloc`/`calloc` at the C runtime level. Detours works by rewriting the first few bytes of target functions with a jump to our hooks.\n\n**Why Detours over alternatives:**\n- **MinHook**: Does NOT support ARM64 (only x86/x64)\n- **IAT Hooking**: Complex, requires hooking each loaded module separately\n- **ETW (Event Tracing)**: Requires admin privileges, high overhead\n- **Detours**: Supports ARM64, x64, x86, ARM - official Microsoft library, MIT licensed\n\n### Implementation\n\n#### Files Modified/Added\n- `vendor/Detours/` - Microsoft Detours source (vendored)\n- `CMakeLists.txt` - Added Detours to Windows build with architecture-specific disassembler\n- `src/source/libscalene_windows.cpp` - Added native hooks using Detours\n\n#### CMakeLists.txt Changes\n```cmake\n# Microsoft Detours sources for native malloc/free hooking\nset(DETOURS_SOURCES\n    vendor/Detours/src/detours.cpp\n    vendor/Detours/src/modules.cpp\n    vendor/Detours/src/disasm.cpp\n    vendor/Detours/src/image.cpp\n    vendor/Detours/src/creatwth.cpp\n)\n\n# Add architecture-specific disassembler\nif(SCALENE_ARCH STREQUAL \"ARM64\")\n    list(APPEND DETOURS_SOURCES vendor/Detours/src/disolarm64.cpp)\nelseif(SCALENE_ARCH STREQUAL \"X64\")\n    list(APPEND DETOURS_SOURCES vendor/Detours/src/disolx64.cpp)\nelseif(SCALENE_ARCH STREQUAL \"X86\")\n    list(APPEND DETOURS_SOURCES vendor/Detours/src/disolx86.cpp)\nendif()\n\ntarget_compile_definitions(scalene PRIVATE DETOURS_INTERNAL)\n```\n\n#### Native Hook Implementation\n```cpp\n#include \"detours.h\"\n\n// Original function pointers (Detours fills these with trampolines)\nstatic void* (__cdecl *Real_malloc)(size_t) = malloc;\nstatic void (__cdecl *Real_free)(void*) = free;\nstatic void* (__cdecl *Real_realloc)(void*, size_t) = realloc;\nstatic void* (__cdecl *Real_calloc)(size_t, size_t) = calloc;\n\n// Recursion guard - CRITICAL for preventing infinite loops\nstatic bool g_in_native_hook = false;\n\n// Coordination with Python allocator hooks\nstatic bool g_in_python_allocator = false;\n\nstatic void* __cdecl Hooked_malloc(size_t size) {\n    // Check recursion guard FIRST - track_native_alloc may call malloc internally\n    if (g_in_native_hook || g_in_python_allocator) {\n        return Real_malloc(size);\n    }\n\n    g_in_native_hook = true;\n    void* ptr = Real_malloc(size);\n    if (ptr) {\n        track_native_alloc(ptr, size);\n        if (!p_scalene_done) {\n            TheHeapWrapper::register_malloc(size, ptr, false);  // false = native\n        }\n    }\n    g_in_native_hook = false;\n    return ptr;\n}\n\nbool install_native_hooks() {\n    DetourRestoreAfterWith();\n    DetourTransactionBegin();\n    DetourUpdateThread(GetCurrentThread());\n\n    DetourAttach(&(PVOID&)Real_malloc, Hooked_malloc);\n    DetourAttach(&(PVOID&)Real_free, Hooked_free);\n    DetourAttach(&(PVOID&)Real_realloc, Hooked_realloc);\n    DetourAttach(&(PVOID&)Real_calloc, Hooked_calloc);\n\n    return DetourTransactionCommit() == NO_ERROR;\n}\n```\n\n### Critical Bug Fix: Recursion Guard Order\n\n**Problem**: The native hooks use `std::unordered_map` for size tracking, which internally calls `malloc`. If the recursion guard was checked AFTER calling tracking functions, infinite recursion occurred:\n\n1. User code calls `malloc`\n2. `Hooked_malloc` is called\n3. `track_native_alloc(ptr, size)` is called (hash map insert)\n4. Hash map internally calls `malloc` for bucket allocation\n5. `Hooked_malloc` is called again (recursion!)\n6. Since `g_in_native_hook` wasn't set yet, we recurse infinitely → stack overflow\n\n**Fix**: Check and set `g_in_native_hook` at the VERY BEGINNING of each hook, BEFORE any operations that might allocate:\n\n```cpp\nstatic void* __cdecl Hooked_malloc(size_t size) {\n    // MUST check recursion guard FIRST\n    if (g_in_native_hook || g_in_python_allocator) {\n        return Real_malloc(size);  // Bypass hook\n    }\n\n    g_in_native_hook = true;  // Set BEFORE any allocating operations\n    // ... rest of hook logic ...\n    g_in_native_hook = false;\n    return ptr;\n}\n```\n\n### Free Size Tracking\n\n**Problem**: `_msize()` doesn't work reliably for custom allocators (numpy uses aligned allocations with `_aligned_malloc`).\n\n**Solution**: Manual size tracking with a hash map:\n\n```cpp\nstatic std::unordered_map<void*, size_t> g_native_alloc_sizes;\nstatic CRITICAL_SECTION g_native_alloc_sizes_lock;\n\nstatic void track_native_alloc(void* ptr, size_t size) {\n    EnterCriticalSection(&g_native_alloc_sizes_lock);\n    g_native_alloc_sizes[ptr] = size;\n    LeaveCriticalSection(&g_native_alloc_sizes_lock);\n}\n\nstatic size_t untrack_native_alloc(void* ptr) {\n    EnterCriticalSection(&g_native_alloc_sizes_lock);\n    auto it = g_native_alloc_sizes.find(ptr);\n    size_t size = (it != g_native_alloc_sizes.end()) ? it->second : 0;\n    if (it != g_native_alloc_sizes.end()) g_native_alloc_sizes.erase(it);\n    LeaveCriticalSection(&g_native_alloc_sizes_lock);\n    return size;\n}\n```\n\n### Coordination Between Python and Native Hooks\n\nTo prevent double-counting allocations that go through both Python's allocator AND the native malloc:\n\n1. Python allocator hooks set `g_in_python_allocator = true` when active\n2. Native malloc hooks check this flag and skip if Python allocator is handling it\n3. Each allocation is counted exactly once\n\n```cpp\n// In Python allocator hook:\nstatic void* scalene_malloc(void* ctx, size_t len) {\n    g_in_python_allocator = true;  // Prevent native hooks\n    void* ptr = g_original_mem_allocator.malloc(...);\n    // ... tracking code ...\n    g_in_python_allocator = false;\n    return ptr;\n}\n```\n\n## Fixes Applied\n\n### 1. **ctypes 64-bit Pointer Fix** (Critical)\n- Added `restype` declarations for all Windows API functions that return handles or pointers\n- `MapViewOfFile.restype = ctypes.c_void_p` - returns memory address\n- `OpenFileMappingW.restype = wintypes.HANDLE` - returns handle\n- Also set `argtypes` for functions taking pointers\n\n### 2. Data Format Fix\nChanged malloc/free output from tab-separated 4-field format to comma-separated 9-field format matching Unix:\n```\nM,alloc_time,count,python_fraction,pid,pointer,filename,lineno,bytei\\n\\n\n```\n\n### 3. Removed `thread_local` Variables\nWindows DLLs loaded with `LoadLibrary`/ctypes don't properly support `thread_local` variables. Changed all to static variables:\n- `mallocSampler` and `memcpySampler`\n- `g_pythonCount`, `g_cCount`\n- `g_lastMallocTrigger`, `g_freedLastMallocTrigger`\n- `g_memcpyOps`\n- `inMalloc` (for recursion guard)\n\n### 4. Added Windows Memory Polling\nSince Unix signals (SIGXCPU/SIGXFSZ) don't exist on Windows, added a polling thread in `scalene_signal_manager.py`:\n- `_windows_memory_poll_loop()` - polls every 10ms\n- Triggers `_alloc_sigqueue_processor` and `_memcpy_sigqueue_processor`\n- Started when memory profiling is enabled on Windows\n\n### 5. Safety Checks in Allocator Hooks\nAdded null checks for original allocator function pointers to prevent crashes if allocation hooks are called before initialization.\n\n## Test Results\n\nRunning the profiler now shows memory profiling data being collected:\n```\nmalloc_calls=113807912, samples=595, logged=595\n```\n\nThe profiler correctly tracks:\n- Python vs native time\n- Memory allocations with line attribution\n- Memory timeline/growth rate\n\n## Build Instructions\n\n```bash\n# Configure with CMake (for ARM64 native)\ncmake -B build -A ARM64 -DPython3_ROOT_DIR=\"C:\\Users\\emery\\AppData\\Local\\Programs\\Python\\Python311-arm64\"\n\n# Build the DLL\nMSBuild.exe build/scalene.sln -p:Configuration=Release -p:Platform=ARM64 -t:scalene\n\n# DLL is automatically placed in scalene\\ directory\n\n# Run profiler\npython -m scalene --cli --cpu --memory test\\testme.py\n```\n\n## Key Differences from Unix Implementation\n\n| Aspect | Unix | Windows |\n|--------|------|---------|\n| Native malloc hooking | LD_PRELOAD | **Microsoft Detours** (inline function hooking) |\n| Python allocator | PyMem_SetAllocator | PyMem_SetAllocator (same) |\n| Signals | SIGXCPU/SIGXFSZ | Polling thread |\n| Shared Memory | /tmp files + mmap | Named shared memory |\n| Symbol Lookup | dlsym(RTLD_DEFAULT) | GetProcAddress + accessor functions |\n| Size Tracking | malloc_usable_size | Manual hash map (\\_msize unreliable) |\n| Thread-local | `thread_local` | Static variables (GIL protects) |\n| Pointer handling | Native 64-bit | **Requires explicit ctypes declarations** |\n| Architecture support | All | ARM64, x64, x86 (via Detours) |\n\n## Learnings\n\n### 1. ctypes Default Return Types Are Dangerous on 64-bit Windows\n- **Always** set `restype` for any Windows API function that returns a handle or pointer\n- Default `c_int` (32-bit) silently truncates 64-bit values\n- This causes delayed crashes that are hard to debug (crash happens when truncated pointer is used, not when it's returned)\n- Use `ctypes.c_void_p` for memory addresses, `wintypes.HANDLE` for handles\n\n### 2. Debugging Methodology That Worked\nThe crash was isolated using **systematic component elimination**:\n1. First confirmed DLL was the cause by renaming it (profiler ran without crash)\n2. Tested with allocator hooks disabled - still crashed (ruled out hooks as cause)\n3. Tested with only shared memory initialization - still crashed (narrowed to shared memory)\n4. Examined shared memory code and found the ctypes issue\n\n### 3. Windows DLL Loading Constraints\n- `thread_local` variables don't work reliably in DLLs loaded via `LoadLibrary`/ctypes\n- Static variables work fine since Python's GIL serializes access\n- DLL entry point (`DllMain`) has severe restrictions - avoid complex initialization there\n\n### 4. Build System Considerations\n- CMake generates Visual Studio solutions that work well for cross-platform builds\n- ARM64 native builds require explicit `-A ARM64` and matching Python version\n- MSBuild can be invoked directly for rebuilds without re-running CMake\n\n### 5. Windows vs Unix IPC\n- Named shared memory on Windows uses `Local\\` prefix for per-session namespace\n- Windows Events can replace Unix signals but polling is simpler for this use case\n- Mutexes on Windows are more heavyweight than Unix futexes\n\n### 6. Recursion Guards in malloc Hooks Must Come FIRST\n- **Critical**: Any code in a malloc hook that uses STL containers (std::unordered_map, std::vector, etc.) may internally call malloc\n- The recursion guard (`g_in_native_hook`) MUST be checked and set BEFORE any other operations\n- Failing to do this causes infinite recursion → stack overflow → exit code 127 or crash\n- Pattern: `if (guard) return original(); guard = true; ... ; guard = false; return result;`\n\n### 7. MinHook Does NOT Support ARM64\n- MinHook is a popular inline hooking library but only supports x86 and x64\n- Microsoft Detours supports ARM64, ARM, x86, x64, and IA64\n- Detours is MIT licensed (open source since 2018) and very well tested\n- Use architecture-specific disassemblers: `disolarm64.cpp` for ARM64, `disolx64.cpp` for x64\n\n### 8. _msize() Is Unreliable for Custom Allocators\n- `_msize()` only works for standard CRT heap allocations\n- numpy and other libraries use aligned allocations (`_aligned_malloc`) which `_msize` doesn't handle\n- Solution: Manual size tracking with a hash map, storing size at allocation time\n- This adds ~10% overhead but is necessary for accurate free tracking\n\n### 9. Coordination Between Multiple Hook Layers\n- When hooking at both Python allocator level AND native malloc level, coordination is essential\n- Use a flag (`g_in_python_allocator`) to prevent native hooks from double-counting Python allocations\n- Pattern: Set flag before calling original allocator, clear after\n- This ensures each allocation is tracked exactly once\n\n## Next Steps\n\n### High Priority\n1. **x64 Build and Testing**: Current implementation tested only on ARM64. Need to verify x64 builds work correctly with Detours.\n\n2. **Unicode Console Output**: The `UnicodeEncodeError` for sparkline characters could be handled more gracefully:\n   - Detect console encoding and fall back to ASCII sparklines\n   - Or auto-set `PYTHONIOENCODING=utf-8` when running on Windows\n\n3. **Performance Optimization**: The polling thread polls every 10ms. Consider:\n   - Using Windows Events for more efficient signaling\n   - Adaptive polling rate based on allocation frequency\n\n### Medium Priority\n4. **Multi-Process Support**: Test and fix any issues with profiling child processes on Windows (the Unix `redirect_python` mechanism may need Windows adaptation).\n\n5. **GPU Profiling on Windows**: Verify NVIDIA GPU profiling works on Windows (pynvml should work but needs testing).\n\n6. **CI/CD Integration**: Add Windows builds to GitHub Actions workflow:\n   - Build DLL for both x64 and ARM64\n   - Run tests on Windows\n   - Include DLL in wheel packages\n\n### Low Priority\n7. **Windows Event-Based Signaling**: Replace polling with proper Windows Events for lower latency and CPU usage:\n   - DLL already creates events (`ScaleneMallocEvent`, etc.)\n   - Python side would use `WaitForMultipleObjects` instead of polling\n\n8. **Memory Leak Detection**: The `--memory-leak-detector` feature may need Windows-specific testing.\n\n9. **Web UI Testing**: Verify the web-based GUI works correctly on Windows (browser launching, port binding).\n\n### Completed\n- ~~**Native Library Memory Tracking**: Implement malloc/free hooking for numpy, pandas, etc.~~ ✅ Done (2024-12-17) - Using Microsoft Detours\n\n## Debugging Tips for Future Issues\n\n### Useful Debug Techniques\n```python\n# Add to scalene_mapfile.py to debug shared memory issues\nprint(f\"Handle value: {handle:#x}\", file=sys.stderr)\nprint(f\"View address: {view:#x}\", file=sys.stderr)\n\n# Check if pointer looks valid (should have high bits set on 64-bit)\nif view < 0x100000000:\n    print(\"WARNING: Pointer may be truncated!\", file=sys.stderr)\n```\n\n### Building with Debug Output\n```cpp\n// In libscalene_windows.cpp, temporarily add:\nfprintf(stderr, \"DEBUG: ptr=%p, size=%zu\\n\", ptr, size);\n```\n\nThen rebuild with:\n```bash\nMSBuild.exe build/scalene.sln -p:Configuration=Release -p:Platform=ARM64 -t:scalene\n```\n\n### Common Windows Error Codes\n- `0xC0000005` (3221225477) - Access Violation (invalid memory access)\n- `0xC0000008` - Invalid Handle\n- `0xC000001D` - Illegal Instruction (wrong architecture)\n- Error 193 - \"Not a valid Win32 application\" (architecture mismatch)\n\n## References\n\n- Python Memory Allocator API: https://docs.python.org/3/c-api/memory.html\n- Windows Named Shared Memory: https://docs.microsoft.com/en-us/windows/win32/memory/creating-named-shared-memory\n- CMake Windows DLL: https://cmake.org/cmake/help/latest/prop_tgt/WINDOWS_EXPORT_ALL_SYMBOLS.html\n- Windows thread_local issues: https://devblogs.microsoft.com/cppblog/c11-thread-local-storage-and-dll-load-failure/\n- **ctypes 64-bit pointers**: https://docs.python.org/3/library/ctypes.html#return-types\n- **Microsoft Detours**: https://github.com/microsoft/Detours - Official Microsoft library for inline function hooking (MIT license)\n- Detours Wiki: https://github.com/microsoft/Detours/wiki - API documentation and examples\n"

Weicker,  CACM Vol 27, No 10, 10/84 pg. 1013.\n\n                Translated from ADA to C by Rick Richardson.\n                Every method to preserve ADA-likeness has been used,\n                at the expense of C-ness.\n\n                Translated from C to Python by Guido van Rossum.\n\nVersion History:\n\n                Version 1.1 corrects two bugs in version 1.0:\n\n                First, it leaked memory: in Proc1(), NextRecord ends\n                up having a pointer to itself.  I have corrected this\n                by zapping NextRecord.PtrComp at the end of Proc1().\n\n                Second, Proc3() used the operator != to compare a\n                record to None.  This is rather inefficient and not\n                true to the intention of the original benchmark (where\n                a pointer comparison to None is intended; the !=\n                operator attempts to find a method __cmp__ to do value\n                comparison of the record).  Version 1.1 runs 5-10\n                percent faster than version 1.0, so benchmark figures\n                of different versions can't be compared directly.\n\n\"\"\"\n\nLOOPS = 500000\n\nimport time  # from time import clock\n\n__version__ = \"1.1\"\n\n[Ident1, Ident2, Ident3, Ident4, Ident5] = range(1, 6)\n\n\nclass Record:\n\n    def __init__(self, PtrComp=None, Discr=0, EnumComp=0, IntComp=0, StringComp=0):\n        self.PtrComp = PtrComp\n        self.Discr = Discr\n        self.EnumComp = EnumComp\n        self.IntComp = IntComp\n        self.StringComp = StringComp\n\n    def copy(self):\n        return Record(\n            self.PtrComp, self.Discr, self.EnumComp, self.IntComp, self.StringComp\n        )\n\n\nTRUE = 1\nFALSE = 0\n\n\ndef main(loops=LOOPS):\n    benchtime, stones = pystones(loops)\n    print(\"Pystone(%s) time for %d passes = %g\" % (__version__, loops, benchtime))\n    print(\"This machine benchmarks at %g pystones/second\" % stones)\n\n\ndef pystones(loops=LOOPS):\n    return Proc0(loops)\n\n\nIntGlob = 0\nBoolGlob = FALSE\nChar1Glob = \"\\0\"\nChar2Glob = \"\\0\"\nArray1Glob = [0] * 51\nArray2Glob = [x[:] for x in [Array1Glob] * 51]\nPtrGlb = None\nPtrGlbNext = None\n\n\ndef Proc0(loops=LOOPS):\n    global IntGlob\n    global BoolGlob\n    global Char1Glob\n    global Char2Glob\n    global Array1Glob\n    global Array2Glob\n    global PtrGlb\n    global PtrGlbNext\n\n    starttime = time.perf_counter()\n    for i in range(loops):\n        pass\n    nulltime = time.perf_counter() -

It runs orders of magnitude faster than many other profilers\nwhile delivering far more detailed information. It is also the first\nprofiler ever to incorporate AI-powered proposed optimizations.\n\nAI-powered optimization suggestions\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n   **Note**\n\n   To enable AI-powered optimization suggestions, you need to enter an\n   `OpenAI key <https://openai.com/api/>`__ in the box under “Advanced\n   options”. *Your account will need to have a positive balance for this\n   to work* (check your balance at\n   https://platform.openai.com/account/usage).\n\nOnce you’ve entered your OpenAI key (see above), click on the lightning\nbolt (⚡) beside any line or the explosion (💥) for an entire region of\ncode to generate a proposed optimization. Click on a proposed\noptimization to copy it to the clipboard.\n\nYou can click as many times as you like on the lightning bolt or\nexplosion, and it will generate different suggested optimizations. Your\nmileage may vary, but in some cases, the suggestions are quite\nimpressive (e.g., order-of-magnitude improvements).\n\nQuick Start\n~~~~~~~~~~~\n\nInstalling Scalene:\n^^^^^^^^^^^^^^^^^^^\n\n.. code:: console\n\n   python3 -m pip install -U scalene\n\nor\n\n.. code:: console\n\n   conda install -c conda-forge scalene\n\nUsing Scalene:\n^^^^^^^^^^^^^^\n\nAfter installing Scalene, you can use Scalene at the command line, or as\na Visual Studio Code extension.\n\n.. raw:: html\n\n   <details>\n\n.. raw:: html\n\n   <summary>\n\nUsing the Scalene VS Code Extension:\n\n.. raw:: html\n\n   </summary>\n\nFirst, install the Scalene extension from the VS Code Marketplace or by\nsearching for it within VS Code by typing Command-Shift-X (Mac) or\nCtrl-Shift-X (Windows).

We highly recommend watching this video!\n\n|Scalene presentation at PyCon 2021|\n\nFast and Accurate\n~~~~~~~~~~~~~~~~~\n\n-  Scalene is **fast**. It uses sampling instead of instrumentation or\n   relying on Python’s tracing facilities. Its overhead is typically no\n   more than 10-20% (and often less).\n\n-  Scalene is **accurate**. We tested CPU profiler accuracy and found\n   that Scalene is among the most accurate profilers, correctly\n   measuring time taken.\n\n.. figure::\n   https://github.com/plasma-umass/scalene/raw/master/docs/cpu-accuracy-comparison.png\n   :alt: Profiler accuracy\n\n   Profiler accuracy\n\n-  Scalene performs profiling **at the line level** *and* **per\n   function**, pointing to the functions and the specific lines of code\n   responsible for the execution time in your program.\n\nCPU profiling\n~~~~~~~~~~~~~\n\n-  Scalene **separates out time spent in Python from time in native\n   code** (including libraries). Most Python programmers aren’t going to\n   optimize the performance of native code (which is usually either in\n   the Python implementation or external libraries), so this helps\n   developers focus their optimization efforts on the code they can\n   actually improve.\n-  Scalene **highlights hotspots** (code accounting for significant\n   percentages of CPU time or memory allocation) in red, making them\n   even easier to spot.\n-  Scalene also separates out **system time**, making it easy to find\n   I/O bottlenecks.\n\nGPU profiling\n~~~~~~~~~~~~~\n\n-  Scalene reports **GPU time** (currently limited to NVIDIA-based\n   systems).\n\nMemory profiling\n~~~~~~~~~~~~~~~~\n\n-  Scalene **profiles memory usage**. In addition to tracking CPU usage,\n   Scalene also points to the specific lines of code responsible for\n   memory growth. It accomplishes this via an included specialized\n   memory allocator.\n-  Scalene separates out the percentage of **memory consumed by Python\n   code vs. native code**.\n-  Scalene produces **per-line memory profiles**.\n-  Scalene **identifies lines with likely memory leaks**.\n-  Scalene **profiles copying volume**, making it easy to spot\n   inadvertent copying, especially due to crossing Python/library\n   boundaries (e.g., accidentally converting ``numpy`` arrays into\n   Python arrays, and vice versa).\n\nOther features\n~~~~~~~~~~~~~~\n\n-  Scalene can produce **reduced profiles** (via ``--reduced-profile``)\n   that only report lines that consume more than 1% of CPU or perform at\n   least 100 allocations.\n-  Scalene supports ``@profile`` decorators to profile only specific\n   functions.\n-  When Scalene is profiling a program launched in the background (via\n   ``&``), you can **suspend and resume profiling**.\n\nComparison to Other Profilers\n=============================\n\nPerformance and Features\n------------------------\n\nBelow is a table comparing the **performance and features** of various\nprofilers to Scalene.\n\n.. figure::\n   https://raw.githubusercontent.com/plasma-umass/scalene/master/docs/images/profiler-comparison.png\n   :alt: Performance and feature comparison\n\n   Performance and feature comparison\n\n-  **Slowdown**: the slowdown when running a benchmark from the\n   Pyperformance suite. Green means less than 2x overhead. Scalene’s\n   overhead is just a 35% slowdown.\n\nScalene has all of the following features, many of which only Scalene\nsupports:\n\n-  **Lines or functions**: does the profiler report information only for\n   entire functions, or for every line – Scalene does both.\n-  **Unmodified Code**: works on unmodified code.\n-  **Threads**: supports Python threads.\n-  **Multiprocessing**: supports use of the ``multiprocessing`` library\n   – *Scalene only*\n-  **Python vs. C time**: breaks out time spent in Python vs. native\n   code (e.g., libraries) – *Scalene only*\n-  **System time**: breaks out system time (e.g., sleeping or performing\n   I/O) – *Scalene only*\n-  **Profiles memory**: reports memory consumption per line / function\n-  **GPU**: reports time spent on an NVIDIA GPU (if present) – *Scalene\n   only*\n-  **Memory trends**: reports memory use over time per line / function –\n   *Scalene only*\n-  **Copy volume**: reports megabytes being copied per second – *Scalene\n   only*\n-  **Detects leaks**: automatically pinpoints lines responsible for\n   likely memory leaks – *Scalene only*\n\nOutput\n------\n\nIf you include the ``--cli`` option, Scalene prints annotated source\ncode for the program being profiled (as text, JSON (``--json``), or HTML\n(``--html``)) and any modules it uses in the same directory or\nsubdirectories (you can optionally have it ``--profile-all`` and only\ninclude files with at least a ``--cpu-percent-threshold`` of time).

There are several options:\n\n1. Use ``--reduced-profile`` to include only lines and files with\n   memory/CPU/GPU activity.\n2. Use ``--profile-only`` to include only filenames containing specific\n   strings (as in, ``--profile-only foo,bar,baz``).\n3. Decorate functions of interest with ``@profile`` to have Scalene\n   report *only* those functions.\n4. Turn profiling on and off programmatically by importing Scalene\n   profiler (``from scalene import scalene_profiler``) and then turning\n   profiling on and off via ``scalene_profiler.start()`` and\n   ``scalene_profiler.stop()``. By default, Scalene runs with profiling\n   on, so to delay profiling until desired, use the ``--off``\n   command-line option (``scalene run --off yourprogram.py``).\n\n.. raw:: html\n\n   </details>\n\n.. raw:: html\n\n   <details>\n\n.. raw:: html\n\n   <summary>\n\nHow do I run Scalene in PyCharm?\n\n.. raw:: html\n\n   </summary>\n\n**A:** In PyCharm, you can run Scalene at the command line by opening\nthe terminal at the bottom of the IDE and running a Scalene command\n(e.g., ``scalene run <your program>``). Then use ``scalene view --html``\nto generate an HTML file (``scalene-profile.html``) that you can view in the IDE.\n\n.. raw:: html\n\n   </details>\n\n.. raw:: html\n\n   <details>\n\n.. raw:: html\n\n   <summary>\n\nHow do I use Scalene with Django?\n\n.. raw:: html\n\n   </summary>\n\n**A:** Pass in the ``--noreload`` option (see\nhttps://github.com/plasma-umass/scalene/issues/178).\n\n.. raw:: html\n\n   </details>\n\n.. raw:: html\n\n   <details>\n\n.. raw:: html\n\n   <summary>\n\nDoes Scalene work with gevent/Greenlets?\n\n.. raw:: html\n\n   </summary>\n\n**A:** Yes!

Coordinates CPU, memory, and GPU profiling by delegating to specialized modules (`ScaleneCPUProfiler`, `ScaleneTracing`, `ScaleneMemoryProfiler`).\n\n* `scalene_signals.py`:\n  Defines the Unix signals that Scalene uses (some of which must be kept in sync with `include/sampleheap.hpp`).\n\n* `scalene_statistics.py`:\n  Operations for managing the statistics generated by Scalene.\n\n* `scalene_tracing.py`:\n  `ScaleneTracing` handles tracing decisions and file filtering. Determines which files and functions should be profiled based on exclusion rules, profile-only patterns, and system library detection. Uses `lru_cache` for performance.\n\n* `scalene_version.py`:\n  The version number of Scalene which ultimately is reflected on `pypi` (for `pip` installs, used by `setup.py` in the top level directory).\n  \n"

    "content": "# TypeScript Conversion Plan for Scalene GUI\n\n## Overview\n\nConverting the Scalene GUI JavaScript files to TypeScript for improved type safety, better IDE support, and easier maintenance.\n\n## Build Configuration\n\n- **Bundler**: esbuild (fast, simple, no webpack overhead)\n- **Type Checker**: TypeScript compiler (tsc --noEmit)\n- **Target**: ES2020\n- **Module System**: ESNext with bundler resolution\n\n### package.json Scripts\n\n```json\n{\n  \"scripts\": {\n    \"build\": \"esbuild scalene-gui.ts --bundle --minify --sourcemap --target=es2020 --outfile=scalene-gui-bundle.js\",\n    \"build:dev\": \"esbuild scalene-gui.ts --bundle --sourcemap --target=es2020 --outfile=scalene-gui-bundle.js\",\n    \"watch\": \"esbuild scalene-gui.ts --bundle --sourcemap --target=es2020 --outfile=scalene-gui-bundle.js --watch\",\n    \"typecheck\": \"tsc --noEmit\"\n  }\n}\n```\n\n## Conversion Status\n\n### Completed\n\n- [x] `utils.ts` - Utility functions (escapeHTML, extractCode, makeTextRecursivelySelectable)\n- [x] `openai.ts` - OpenAI API integration with proper interfaces\n- [x] `ollama.ts` - Ollama local LLM integration\n- [x] `amazon.ts` - AWS Bedrock integration (Anthropic and OpenAI-style responses)\n- [x] `azure.ts` - Azure OpenAI integration\n- [x] `persistence.ts` - LocalStorage state persistence\n- [x] `gui-elements.ts` - Vega-Lite chart builders with LineProfile/FileProfile interfaces\n- [x] `optimizations.ts` - AI optimization request handling\n- [x] `scalene-gui.ts` - Main entry point (largest file, imports all others)\n- [x] `scalene-demo.ts` - Demo functionality\n- [x] `scalene-fetch.ts` - Profile fetching utilities\n- [x] `prism.d.ts` - Type declarations for Prism.js\n- [x] `tablesort.d.ts` - Type declarations for Tablesort.js\n\n### External Libraries (Kept as JS with type declarations)\n\n- `prism.js` - Syntax highlighting (external library, with prism.d.ts declarations)\n- `tablesort.js` - Table sorting (external library, with tablesort.d.ts declarations)\n\n## Type Definitions Added\n\n### Interfaces\n\n- `OpenAIChoice`, `OpenAIResponse` - OpenAI API responses\n- `OllamaModel`, `OllamaTagsResponse`, `OllamaMessage`, `OllamaResponse` - Ollama API\n- `AnthropicResponse`, `OpenAIStyleResponse` - Amazon Bedrock responses\n- `AzureOpenAIChoice`, `AzureOpenAIResponse` - Azure API responses\n- `LineProfile`, `FileProfile`, `ChartParams` - Profile data structures for Vega-Lite charts\n- `LineData`, `FunctionData`, `FileData`, `Profile` - Main profile data types\n- `Column`, `TableParams`, `OptimizationParams` - GUI-specific types\n\n### DOM Element Types\n\nAll DOM element access uses proper type assertions:\n```typescript\nconst element = document.getElementById(\"my-id\") as HTMLInputElement | null;\n```\n\n## Dependencies\n\n```json\n{\n  \"devDependencies\": {\n    \"@types/node\": \"^20.10.0\",\n    \"@types/prismjs\": \"^1.26.0\",\n    \"esbuild\": \"^0.24.0\",\n    \"typescript\": \"^5.3.3\"\n  },\n  \"dependencies\": {\n    \"@aws-sdk/client-bedrock-runtime\": \"^3.729.0\",\n    \"buffer\": \"^6.0.3\",\n    \"vega\": \"^5.30.0\",\n    \"vega-embed\": \"^6.28.0\",\n    \"vega-lite\": \"^5.21.0\"\n  }\n}\n```\n\n## Build Steps\n\n1. Install dependencies: `npm install`\n2. Type check: `npm run typecheck`\n3. Build bundle: `npm run build`\n4. Development build (unminified): `npm run build:dev`\n5. Watch mode: `npm run watch`\n\n## Notes\n\n- Using `strictNullChecks: true` for better null safety\n- All external API responses have explicit interface definitions\n- DOM element access uses null-safe patterns with optional chaining\n- External JS libraries (`prism.js`, `tablesort.js`) kept as-is with `.d.ts` declaration files\n- Window functions exposed globally for HTML onclick handlers\n- Build produces ~1.1MB minified bundle with source maps\n\n## Migration Complete\n\nAll JavaScript files have been successfully converted to TypeScript. The original `.js` files can be removed once the TypeScript version is verified in production.\n"

For example, the CSS language definition\n       * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded\n       * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the\n       * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do\n       * this:\n       *\n       * ```js\n       * Prism.languages.markup.style = {\n       *     // token\n       * };\n       * ```\n       *\n       * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens\n       * before existing tokens. For the CSS example above, you would use it like this:\n       *\n       * ```js\n       * Prism.languages.insertBefore('markup', 'cdata', {\n       *     'style': {\n       *         // token\n       *     }\n       * });\n       * ```\n       *\n       * ## Special cases\n       *\n       * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar\n       * will be ignored.\n       *\n       * This behavior can be used to insert tokens after `before`:\n       *\n       * ```js\n       * Prism.languages.insertBefore('markup', 'comment', {\n       *     'comment': Prism.languages.markup.comment,\n       *     // tokens after 'comment'\n       * });\n       * ```\n       *\n       * ## Limitations\n       *\n       * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object\n       * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave\n       * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily\n       * deleting properties which is necessary to insert at arbitrary positions.\n       *\n       * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.\n       * Instead, it will create a new object and replace all references to the target object with the new one. This\n       * can be done without temporarily deleting properties, so the iteration order is well-defined.\n       *\n       * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if\n       * you hold the target object in a variable, then the value of the variable will not change.\n       *\n       * ```js\n       * var oldMarkup = Prism.languages.markup;\n       * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });\n       *\n       * assert(oldMarkup !== Prism.languages.markup);\n       * assert(newMarkup === Prism.languages.markup);\n       * ```\n       *\n       * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the\n       * object to be modified.\n       * @param {string} before The key to insert before.\n       * @param {Grammar} insert An object containing the key-value pairs to be inserted.\n       * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the\n       * object to be modified.\n       *\n       * Defaults to `Prism.languages`.\n       * @returns {Grammar} The new grammar object.\n       * @public\n       */\n      insertBefore: function (inside, before, insert, root) {\n        root = root || /** @type {any} */ (_.languages);\n        var grammar = root[inside];\n        /** @type {Grammar} */\n        var ret = {};\n\n        for (var token in grammar) {\n          if (grammar.hasOwnProperty(token)) {\n            if (token == before) {\n              for (var newToken in insert) {\n                if (insert.hasOwnProperty(newToken)) {\n                  ret[newToken] = insert[newToken];\n                }\n              }\n            }\n\n            // Do not insert token which also occur in insert.

For example, the CSS language definition\n         * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded\n         * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the\n         * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do\n         * this:\n         *\n         * ```js\n         * Prism.languages.markup.style = {\n         *     // token\n         * };\n         * ```\n         *\n         * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens\n         * before existing tokens. For the CSS example above, you would use it like this:\n         *\n         * ```js\n         * Prism.languages.insertBefore('markup', 'cdata', {\n         *     'style': {\n         *         // token\n         *     }\n         * });\n         * ```\n         *\n         * ## Special cases\n         *\n         * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar\n         * will be ignored.\n         *\n         * This behavior can be used to insert tokens after `before`:\n         *\n         * ```js\n         * Prism.languages.insertBefore('markup', 'comment', {\n         *     'comment': Prism.languages.markup.comment,\n         *     // tokens after 'comment'\n         * });\n         * ```\n         *\n         * ## Limitations\n         *\n         * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object\n         * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave\n         * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily\n         * deleting properties which is necessary to insert at arbitrary positions.\n         *\n         * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.\n         * Instead, it will create a new object and replace all references to the target object with the new one.

See\n`PEP 258`_ for an overview of Docutils components.\n\nThe ``docutils.core.publish_*`` convenience functions are the normal\nentry points for using Docutils as a library.\n\nSee `Inside A Docutils Command-Line Front-End Tool`_ for an overview\nof a typical Docutils front-end tool, including how the Publisher\nclass is used.\n\n.. _PEP 258: ../peps/pep-0258.html\n.. _Inside A Docutils Command-Line Front-End Tool: ../howto/cmdline-tool.html\n\n\nPublisher Convenience Functions\n===============================\n\nEach of these functions set up a ``docutils.core.Publisher`` object,\nthen call its ``publish`` method.  ``docutils.core.Publisher.publish``\nhandles everything else.  There are several convenience functions in\nthe ``docutils.core`` module:\n\n:_`publish_cmdline()`: for command-line front-end tools, like\n  ``rst2html.py``.  There are several examples in the ``tools/``\n  directory.  A detailed analysis of one such tool is in `Inside A\n  Docutils Command-Line Front-End Tool`_\n\n:_`publish_file()`: for programmatic use with file-like I/O.  In\n  addition to writing the encoded output to a file, also returns the\n  encoded output as a string.\n\n:_`publish_string()`: for programmatic use with string I/O.  Returns\n  the encoded output as a string.\n\n:_`publish_parts()`: for programmatic use with string input; returns a\n  dictionary of document parts.  Dictionary keys are the names of\n  parts, and values are Unicode strings; encoding is up to the client.\n  Useful when only portions of the processed document are desired.\n  See `publish_parts() Details`_ below.\n\n  There are usage examples in the `docutils/examples.py`_ module.\n\n:_`publish_doctree()`: for programmatic use with string input; returns a\n  Docutils document tree data structure (doctree).  The doctree can be\n  modified, pickled & unpickled, etc., and then reprocessed with\n  `publish_from_doctree()`_.\n\n:_`publish_from_doctree()`: for programmatic use to render from an\n  existing document tree data structure (doctree); returns the encoded\n  output as a string.\n\n:_`publish_programmatically()`: for custom programmatic use.  This\n  function implements common code and is used by ``publish_file``,\n  ``publish_string``, and ``publish_parts``.  It returns a 2-tuple:\n  the encoded string output and the Publisher object.\n\n.. _Inside A Docutils Command-Line Front-End Tool: ../howto/cmdline-tool.html\n.. _docutils/examples.py: ../../docutils/examples.py\n\n\nConfiguration\n-------------\n\nTo pass application-specific setting defaults to the Publisher\nconvenience functions, use the ``settings_overrides`` parameter.  Pass\na dictionary of setting names & values, like this::\n\n    overrides = {'input_encoding': 'ascii',\n                 'output_encoding': 'latin-1'}\n    output = publish_string(..., settings_overrides=overrides)\n\nSettings from command-line options override configuration file\nsettings, and they override application defaults.  For details, see\n`Docutils Runtime Settings`_.  See `Docutils Configuration`_ for\ndetails about individual settings.\n\n.. _Docutils Runtime Settings: ./runtime-settings.html\n.. _Docutils Configuration: ../user/config.html\n\n\nEncodings\n---------\n\nThe default output encoding of Docutils is UTF-8.\nDocutils may introduce some non-ASCII text if you use\n`auto-symbol footnotes`_ or the `\"contents\" directive`_.\n\n.. _auto-symbol footnotes:\n   ../ref/rst/restructuredtext.html#auto-symbol-footnotes\n.. _\"contents\" directive:\n   ../ref/rst/directives.html#table-of-contents\n\n\n``publish_parts()`` Details\n===========================\n\nThe ``docutils.core.publish_parts()`` convenience function returns a\ndictionary of document parts.  Dictionary keys are the names of parts,\nand values are Unicode strings.\n\nEach Writer component may publish a different set of document parts,\ndescribed below.  Not all writers implement all parts.\n\n\nParts Provided By All Writers\n-----------------------------\n\n_`encoding`\n    The output encoding setting.\n\n_`version`\n    The version of Docutils used.\n\n_`whole`\n    ``parts['whole']`` contains the entire formatted document.\n\n\nParts Provided By the HTML Writers\n----------------------------------\n\nHTML4 Writer\n````````````\n\n_`body`\n    ``parts['body']`` is equivalent to parts['fragment_'].  It is\n    *not* equivalent to parts['html_body_'].\n\n_`body_prefix`\n    ``parts['body_prefix']`` contains::\n\n        </head>\n        <body>\n        <div class=\"document\" ...>\n\n    and, if applicable::\n\n        <div class=\"header\">\n        ...\n        </div>\n\n_`body_pre_docinfo`\n    ``parts['body_pre_docinfo]`` contains (as applicable)::\n\n        <h1 class=\"title\">...</h1>\n        <h2 class=\"subtitle\" id=\"...\">...</h2>\n\n_`body_suffix`\n    ``parts['body_suffix']`` contains::\n\n        </div>\n\n    (the end-tag for ``<div class=\"document\">``), the footer division\n    if applicable::\n\n        <div class=\"footer\">\n        ...\n        </div>\n\n    and::\n\n        </body>\n        </html>\n\n_`docinfo`\n    ``parts['docinfo']`` contains the document bibliographic data, the\n    docinfo field list rendered as a table.\n\n_`footer`\n    ``parts['footer']`` contains the document footer content, meant to\n    appear at the bottom of a web page, or repeated at the bottom of\n    every printed page.\n\n_`fragment`\n    ``parts['fragment']`` contains the document body (*not* the HTML\n    ``<body>``).  In other words, it contains the entire document,\n    less the document title, subtitle, docinfo, header, and footer.\n\n_`head`\n    ``parts['head']`` contains ``<meta ... />`` tags and the document\n    ``<title>...</title>``.\n\n_`head_prefix`\n    ``parts['head_prefix']`` contains the XML declaration, the DOCTYPE\n    declaration, the ``<html ...>`` start tag and the ``<head>`` start\n    tag.\n\n_`header`\n    ``parts['header']`` contains the document header content, meant to\n    appear at the top of a web page, or repeated at the top of every\n    printed page.\n\n_`html_body`\n    ``parts['html_body']`` contains the HTML ``<body>`` content, less\n    the ``<body>`` and ``</body>`` tags themselves.\n\n_`html_head`\n    ``parts['html_head']`` contains the HTML ``<head>`` content, less\n    the stylesheet link and the ``<head>`` and ``</head>`` tags\n    themselves.  Since ``publish_parts`` returns Unicode strings and\n    does not know about the output encoding, the \"Content-Type\" meta\n    tag's \"charset\" value is left unresolved, as \"%s\"::\n\n        <meta http-equiv=\"Content-Type\" content=\"text/html; charset=%s\" />\n\n    The interpolation should be done by client code.\n\n_`html_prolog`\n    ``parts['html_prolog]`` contains the XML declaration and the\n    doctype declaration.  The XML declaration's \"encoding\" attribute's\n    value is left unresolved, as \"%s\"::\n\n        <?xml version=\"1.0\" encoding=\"%s\" ?>\n\n    The interpolation should be done by client code.\n\n_`html_subtitle`\n    ``parts['html_subtitle']`` contains the document subtitle,\n    including the enclosing ``<h2 class=\"subtitle\">`` & ``</h2>``\n    tags.\n\n_`html_title`\n    ``parts['html_title']`` contains the document title, including the\n    enclosing ``<h1 class=\"title\">`` & ``</h1>`` tags.\n\n_`meta`\n    ``parts['meta']`` contains all ``<meta ... />`` tags.\n\n_`stylesheet`\n    ``parts['stylesheet']`` contains the embedded stylesheet or\n    stylesheet link.\n\n_`subtitle`\n    ``parts['subtitle']`` contains the document subtitle text and any\n    inline markup.  It does not include the enclosing ``<h2>`` &\n    ``</h2>`` tags.\n\n_`title`\n    ``parts['title']`` contains the document title text and any inline\n    markup.  It does not include the enclosing ``<h1>`` & ``</h1>``\n    tags.\n\n\nPEP/HTML Writer\n```````````````\n\nThe PEP/HTML writer provides the same parts as the `HTML4 writer`_,\nplus the following:\n\n_`pepnum`\n    ``parts['pepnum']`` contains\n\n\nS5/HTML Writer\n``````````````\n\nThe S5/HTML writer provides the same parts as the `HTML4 writer`_.\n\n\nHTML5 Writer\n````````````\n\nThe HTML5 writer provides the same parts as the `HTML4 writer`_.\nHowever, it uses semantic HTML5 elements for the document, header and\nfooter.\n\n\nParts Provided by the LaTeX2e Writer\n------------------------------------\n\nSee the template files for examples how these parts can be combined\ninto a valid LaTeX document.\n\nabstract\n    ``parts['abstract']`` contains the formatted content of the\n    'abstract' docinfo field.\n\nbody\n    ``parts['body']`` contains the document's content.

Defaults specified in the `settings_spec`__ and\n   `settings_defaults`__ attributes for each component_.\n\n   __ SettingsSpec.settings_spec_\n   __ SettingsSpec.settings_defaults_\n\n2. Defaults specified in the `settings_default_overrides`__ attribute\n   for each component_.\n\n   __ SettingsSpec.settings_default_overrides_\n\n3. Settings specified in the `settings_overrides`__ parameter of the\n   `convenience functions`_ resp. the `settings_overrides` attribute of\n   a `Publisher`_ instance.\n\n   __ `settings_overrides parameter`_\n\n4. Settings specified in `active sections`_ of the `configuration files`_\n   in the order described in `Configuration File Sections & Entries`_\n   (if enabled).\n\n5. Command line options (if enabled).\n\nFor details see the ``docutils/__init__.py``, ``docutils/core.py``, and\n``docutils.frontend.py`` modules and the implementation description in\n`Runtime Settings Processing`_.\n\n\n.. _SettingsSpec:\n\nSettingsSpec base class\n=======================\n\n.. note::\n   Implementation details will change with the move to replace the\n   deprecated optparse_ module with argparse_.\n\nThe `docutils.SettingsSpec` base class is inherited by Docutils\ncomponents_ and `frontend.OptionParser`.\nIt defines the following six **attributes**:\n\n.. _SettingsSpec.settings_spec:\n\n`settings_spec`\n   a sequence of\n\n   1. option group title (string or None)\n\n   2. description (string or None)\n\n   3. option tuples with\n\n      a) help text\n      b) options string(s)\n      c) dictionary with keyword arguments for `OptionParser.add_option()`_\n         and an optional \"validator\", a `frontend.validate_*()` function\n         that processes the values (e.g. convert to other data types).\n\n   For examples, see the source of ``frontend.OptionParser.settings_spec``\n   or the `settings_spec` attributes of the Docutils components_.\n\n   .. _SettingsSpec.settings_defaults:\n\n`settings_defaults`\n   for purely programmatic settings\n   (not accessible from command line and configuration files).\n\n   .. _SettingsSpec.settings_default_overrides:\n\n`settings_default_overrides`\n   to override defaults for settings\n   defined in other components' `setting_specs`.\n\n`relative_path_settings`\n   listing settings containing filesystem paths.\n\n   .. _active sections:\n\n`config_section`\n   the configuration file section specific to this\n   component.\n\n`config_section_dependencies`\n   lists configuration files sections\n   that should also be read (before the `config_section`).\n\nThe last two attributes define which configuration file sections are\n\"active\". See also `Configuration File Sections & Entries`_.\n\n\nGlossary\n========\n\n.. _component:\n\ncomponents\n----------\n\nDocutils front-ends and applications combine a selection of\n*components* of the `Docutils Project Model`_.\n\nAll components inherit the `SettingsSpec`_ base class.\nThis means that all instances of ``readers.Reader``, ``parsers.Parser``, and\n``writers.Writer`` are also instances of ``docutils.SettingsSpec``.\n\nFor the determination of runtime settings, ``frontend.OptionParser`` and\nthe `settings_spec parameter`_ in application settings specifications\nare treated as components as well.\n\n\n.. _convenience function:\n\nconvenience functions\n---------------------\n\nApplications usually deploy Docutils by one of the\n`Publisher convenience functions`_.\n\nAll convenience functions accept the following optional parameters:\n\n.. _settings parameter:\n\n`settings`\n  a ``frontend.Values`` instance.\n  If present, it must be complete.\n\n  No further runtime settings processing is done and the\n  following parameters have no effect.\n\n  .. _settings_spec parameter:\n\n`settings_spec`\n  a `SettingsSpec`_ subclass or instance containing the settings\n  specification for the \"Application\" itself.\n  The instance is added to the components_ (after the generic\n  settings, parser, reader, and writer).\n\n  .. _settings_overrides parameter:\n\n`settings_overrides`\n  a dictionary which is used to update the\n  defaults of the components' settings specifications.\n\n  .. _config_section parameter:\n\n`config_section`\n  the name of an application-specific\n  `configuration file section`_ for this application.\n\n  Can be specified instead of a `settings_spec` (a new SettingsSpec_\n  instance that just defines a configuration section will be created)\n  or in addition to a `settings_spec`\n  (overriding its `config_section` attribute).\n\n\nsettings_spec\n-------------\n\nThe name ``settings_spec`` may refer to\n\na) an instance of the SettingsSpec_ class, or\nb) the data structure `SettingsSpec.settings_spec`_ which is used to\n   store settings details.\n\n\n..

Each transform is a\nsubclass of ``docutils.transforms.Transform``.\n\nThere are `transforms added by components`_, others (e.g.\n``parts.Contents``) are added by the parser, if a corresponding directive is\nfound in the document.\n\nTo add a transform, components (objects inheriting from\nDocutils.Component like Readers, Parsers, Writers, Input, Output) overwrite\nthe ``get_transforms()`` method of their base class. After the Reader has\nfinished processing, the Publisher calls\n``Transformer.populate_from_components()`` with a list of components and all\ntransforms returned by the component's ``get_transforms()`` method are\nstored in a `transformer object` attached to the document tree.\n\n\nFor more about transforms and the Transformer object, see also `PEP\n258`_.

If you have any questions,\nplease direct them to the Docutils-develop_ mailing list.\n\nFirst, please download the most current `release tarball`_ and unpack\nit.\n\n.. _Docutils-develop: ../user/mailing-lists.html#docutils-develop\n.. _release tarball: https://docutils.sourceforge.io/#download\n\n\nDependencies\n============\n\nDocutils has the following dependencies:\n\n* Python 3.7 or later is required.\n  Use \">= Python 3.7\" in the dependencies.\n\n* Docutils may optionally make use of the PIL (`Python Imaging\n  Library`_ or Pillow_).  If PIL is present, it is automatically\n  detected by Docutils.\n\n* Docutils recommends the `Pygments`_ syntax hightlighter. If available, it\n  is used for highlighting the content of `code directives`_ and roles as\n  well as included source code files (with the \"code\" option to the include_\n  directive).\n\n* Docutils can use the `recommonmark`_ parser to parse input in\n  the Markdown format (new in 0.17).\n\n.. _Python Imaging Library:\n    https://en.wikipedia.org/wiki/Python_Imaging_Library\n.. _Pillow: https://pypi.org/project/Pillow/\n.. _Pygments: https://pygments.org/\n.. _recommonmark: https://pypi.org/project/recommonmark/\n\n.. _code directives: ../ref/rst/directives.html#code\n.. _include: ../ref/rst/directives.html#include\n\n\nPython Files\n============\n\nThe Docutils Python files must be installed into the\n``site-packages/`` directory of Python.  Running ``python setup.py\ninstall`` should do the trick, but if you want to place the files\nyourself, you can just install the ``docutils/`` directory of the\nDocutils tarball to ``/usr/lib/python/site-packages/docutils/``.  In\nthis case you should also compile the Python files to ``.pyc`` and/or\n``.pyo`` files so that Docutils doesn't need to be recompiled every\ntime it's executed.\n\n\nExecutables\n===========\n\nThe executable front-end tools are located in the ``tools/`` directory\nof the Docutils tarball.\n\nThe ``rst2*.py`` tools are intended for end-users. You should install them\nto ``/usr/bin/``.  You do not need to change the names (e.g. to\n``docutils-rst2html.py``) because the ``rst2`` prefix is unique.\n\n\nDocumentation\n=============\n\nThe documentation should be generated using ``buildhtml.py``.  To\ngenerate HTML for all documentation files, go to the ``tools/``\ndirectory and run::\n\n    # Place html4css1.css in base directory.\n    cp ../docutils/writers/html4css1/html4css1.css ..\n    ./buildhtml.py --stylesheet-path=../html4css1.css ..\n\nThen install the following files to ``/usr/share/doc/docutils/`` (or\nwherever you install documentation):\n\n* All ``.html`` and ``.txt`` files in the base directory.\n\n* The ``docs/`` directory.\n\n  Do not install the contents of the ``docs/`` directory directly to\n  ``/usr/share/doc/docutils/``; it's incomplete and would contain\n  invalid references!\n\n* The ``licenses/`` directory.\n\n* ``html4css1.css`` in the base directory.\n\n\nRemoving the ``.txt`` Files\n---------------------------\n\nIf you are tight with disk space, you can remove all ``.txt`` files in\nthe tree except for:\n\n* those in the ``licenses/`` directory because they have not been\n  processed to HTML and\n\n* ``user/rst/cheatsheet.txt`` and ``user/rst/demo.txt``, which should\n  be readable in source form.\n\nBefore you remove the ``.txt`` files you should rerun ``buildhtml.py``\nwith the ``--no-source-link`` switch to avoid broken references to the\nsource files.\n\n\nOther Files\n===========\n\nYou may want to install the Emacs-Lisp files\n``tools/editors/emacs/*.el`` into the appropriate directory.\n\n\nConfiguration File\n==================\n\nIt is possible to have a system-wide configuration file at\n``/etc/docutils.conf``.  However, this is usually not necessary.  You\nshould *not* install ``tools/docutils.conf`` into ``/etc/``.\n\n\nTests\n=====\n\nWhile you probably do not need to ship the tests with your\ndistribution, you can test your package by installing it and then\nrunning ``alltests.py`` from the ``tests/`` directory of the Docutils\ntarball.\n\nFor more information on testing, view the `Docutils Testing`_ page.\n\n.. _Docutils Testing: https://docutils.sourceforge.io/docs/dev/testing.html\n"

    "content": "===========================================\n Plan for Enthought API Documentation Tool\n===========================================\n\n:Author: David Goodger\n:Contact: docutils-develop@lists.sourceforge.net\n:Date: $Date$\n:Revision: $Revision$\n:Copyright: 2004 by `Enthought, Inc. <http://www.enthought.com>`_\n:License: `Enthought License`_ (BSD-style)\n\n.. _Enthought License: https://docutils.sourceforge.io/licenses/enthought.txt\n\nThis document should be read in conjunction with the `Enthought API\nDocumentation Tool RFP`__ prepared by Janet Swisher.\n\n__ enthought-rfp.html\n\n.. contents::\n.. sectnum::\n\n\nIntroduction\n============\n\nIn March 2004 at I met Eric Jones, president and CTO of `Enthought,\nInc.`_, at `PyCon 2004`_ in Washington DC.  He told me that Enthought\nwas using reStructuredText_ for source code documentation, but they\nhad some issues.  He asked if I'd be interested in doing some work on\na customized API documentation tool.  Shortly after PyCon, Janet\nSwisher, Enthought's senior technical writer, contacted me to work out\ndetails.  Some email, a trip to Austin in May, and plenty of Texas\nhospitality later, we had a project.  This document will record the\ndetails, milestones, and evolution of the project.\n\nIn a nutshell, Enthought is sponsoring the implementation of an open\nsource API documentation tool that meets their needs.  Fortuitously,\ntheir needs coincide well with the \"Python Source Reader\" description\nin `PEP 258`_.  In other words, Enthought is funding some significant\nimprovements to Docutils, improvements that were planned but never\nimplemented due to time and other constraints.  The implementation\nwill take place gradually over several months, on a part-time basis.\n\nThis is an ideal example of cooperation between a corporation and an\nopen-source project.  The corporation, the project, I personally, and\nthe community all benefit.  Enthought, whose commitment to open source\nis also evidenced by their sponsorship of SciPy_, benefits by\nobtaining a useful piece of software, much more quickly than would\nhave been possible without their support.  Docutils benefits directly\nfrom the implementation of one of its core subsystems.  I benefit from\nthe funding, which allows me to justify the long hours to my wife and\nfamily.  All the corporations, projects, and individuals that make up\nthe community will benefit from the end result, which will be great.\n\nAll that's left now is to actually do the work!\n\n.. _PyCon 2004: http://pycon.org/dc2004/\n.. _reStructuredText: https://docutils.sourceforge.io/rst.html\n.. _SciPy: http://www.scipy.org/\n\n\nDevelopment Plan\n================\n\n1. Analyze prior art, most notably Epydoc_ and HappyDoc_, to see how\n   they do what they do.  I have no desire to reinvent wheels\n   unnecessarily.  I want to take the best ideas from each tool,\n   combined with the outline in `PEP 258`_ (which will evolve), and\n   build at least the foundation of the definitive Python\n   auto-documentation tool.\n\n   .. _Epydoc: http://epydoc.sourceforge.net/\n   .. _HappyDoc: http://happydoc.sourceforge.net/\n   .. _PEP 258:\n      https://docutils.sourceforge.io/docs/peps/pep-0258.html#python-source-reader\n\n2. Decide on a base platform.  The best way to achieve Enthought's\n   goals in a reasonable time frame may be to extend Epydoc or\n   HappyDoc.  Or it may be necessary to start fresh.\n\n3. Extend the reStructuredText parser.  See `Proposed Changes to\n   reStructuredText`_ below.\n\n4. Depending on the base platform chosen, build or extend the\n   docstring & doc comment extraction tool.  This may be the biggest\n   part of the project, but I won't be able to break it down into\n   details until more is known.\n\n\nRepository\n==========\n\nIf possible, all software and documentation files will be stored in\nthe Subversion repository of Docutils and/or the base project, which\nare all publicly-available via anonymous pserver access.\n\nThe Docutils project is very open about granting Subversion write\naccess; so far, everyone who asked has been given access.  Any\nEnthought staff member who would like Subversion write access will get\nit.\n\nIf either Epydoc or HappyDoc is chosen as the base platform, I will\nask the project's administrator for CVS access for myself and any\nEnthought staff member who wants it.  If sufficient access is not\ngranted -- although I doubt that there would be any problem -- we may\nhave to begin a fork, which could be hosted on SourceForge, on\nEnthought's Subversion server, or anywhere else deemed appropriate.\n\n\nCopyright & License\n===================\n\nMost existing Docutils files have been placed in the public domain, as\nfollows::\n\n    :Copyright: This document has been placed in the public domain.\n\nThis is in conjunction with the \"Public Domain Dedication\" section of\nCOPYING.txt__.\n\n__ https://docutils.sourceforge.io/COPYING.html\n\nThe code and documentation originating from Enthought funding will\nhave Enthought's copyright and license declaration.  While I will try\nto keep Enthought-specific code and documentation separate from the\nexisting files, there will inevitably be cases where it makes the most\nsense to extend existing files.\n\nI propose the following:\n\n1. New files related to this Enthought-funded work will be identified\n   with the following field-list headers::\n\n       :Copyright: 2004 by Enthought, Inc.\n       :License: Enthought License (BSD Style)\n\n   The license field text will be linked to the license file itself.\n\n2. For significant or major changes to an existing file (more than 10%\n   change), the headers shall change as follows (for example)::\n\n       :Copyright: 2001-2004 by David Goodger\n       :Copyright: 2004 by Enthought, Inc.\n       :License: BSD-style\n\n   If the Enthought-funded portion becomes greater than the previously\n   existing portion, Enthought's copyright line will be shown first.\n\n3. In cases of insignificant or minor changes to an existing file\n   (less than 10% change), the public domain status shall remain\n   unchanged.\n\nA section describing all of this will be added to the Docutils\n`COPYING`__ instructions file.\n\nIf another project is chosen as the base project, similar changes\nwould be made to their files, subject to negotiation.\n\n__ https://docutils.sourceforge.io/COPYING.html\n\n\nProposed Changes to reStructuredText\n====================================\n\nDoc Comment Syntax\n------------------\n\nThe \"traits\" construct is implemented as dictionaries, where\nstandalone strings would be Python syntax errors.  Therefore traits\nrequire documentation in comments.  We also need a way to\ndifferentiate between ordinary \"internal\" comments and documentation\ncomments (doc comments).\n\nJavadoc uses the following syntax for doc comments::\n\n    /**\n     * The first line of a multi-line doc comment begins with a slash\n     * and *two* asterisks.  The doc comment ends normally.\n     */\n\nPython doesn't have multi-line comments; only single-line.  A similar\nconvention in Python might look like this::\n\n    ##\n    # The first line of a doc comment begins with *two* hash marks.\n    # The doc comment ends with the first non-comment line.\n    'data' : AnyValue,\n\n    ## The double-hash-marks could occur on the first line of text,\n    #  saving a line in the source.\n    'data' : AnyValue,\n\nHow to indicate the end of the doc comment? ::\n\n    ##\n    # The first line of a doc comment begins with *two* hash marks.\n    # The doc comment ends with the first non-comment line, or another\n    # double-hash-mark.\n    ##\n    # This is an ordinary, internal, non-doc comment.\n    'data' : AnyValue,\n\n    ## First line of a doc comment, terse syntax.\n    #  Second (and last) line.  Ends here: ##\n    # This is an ordinary, internal, non-doc comment.\n    'data' : AnyValue,\n\nOr do we even need to worry about this case?  A simple blank line\ncould be used::\n\n    ## First line of a doc comment, terse syntax.\n    #  Second (and last) line.  Ends with a blank line.\n\n    # This is an ordinary, internal, non-doc comment.\n    'data' : AnyValue,\n\nOther possibilities::\n\n    #\" Instead of double-hash-marks, we could use a hash mark and a\n    #  quotation mark to begin the doc comment.\n    'data' : AnyValue,\n\n    ## We could require double-hash-marks on every line.  This has the\n    ## added benefit of delimiting the *end* of the doc comment, as\n    ## well as working well with line wrapping in Emacs\n    ## (\"fill-paragraph\" command).\n    # Ordinary non-doc comment.\n    'data' : AnyValue,\n\n    #\" A hash mark and a quotation mark on each line looks funny, and\n    #\" it doesn't work well with line wrapping in Emacs.\n    'data' : AnyValue,\n\nThese styles (repeated on each line) work well with line wrapping in\nEmacs::\n\n    ##  #>  #|  #-  #%  #!  #*\n\nThese styles do *not* work well with line wrapping in Emacs::\n\n    #\"  #'  #:  #)  #.  #/  #@  #$  #^  #=  #+  #_  #~\n\nThe style of doc comment indicator used could be a runtime, global\nand/or per-module setting.  That may add more complexity than it's\nworth though.\n\n\nRecommendation\n``````````````\n\nI recommend adopting \"#*\" on every line::\n\n    # This is an ordinary non-doc comment.\n\n    #* This is a documentation comment, with an asterisk after the\n    #* hash marks on every line.\n    'data' : AnyValue,\n\nI initially recommended adopting double-hash-marks::\n\n    # This is an ordinary non-doc comment.\n\n    ## This is a documentation comment, with double-hash-marks on\n    ## every line.\n    'data' : AnyValue,\n\nBut Janet Swisher rightly pointed out that this could collide with\nordinary comments that are then block-commented.  This applies to\ndouble-hash-marks on the first line only as well.  So they're out.\n\nOn the other hand, the JavaDoc-comment style (\"##\" on the first line\nonly, \"#\" after that) is used in Fredrik Lundh's PythonDoc_.  It may\nbe worthwhile to conform to this syntax, reinforcing it as a standard.\nPythonDoc does not support terse doc comments (text after \"##\" on the\nfirst line).\n\n.. _PythonDoc: http://effbot.org/zone/pythondoc.htm\n\n\nUpdate\n``````\n\nEnthought's Traits system has switched to a metaclass base, and traits\nare now defined via ordinary attributes.  Therefore doc comments are\nno longer absolutely necessary; attribute docstrings will suffice.\nDoc comments may still be desirable though, since they allow\ndocumentation to precede the thing being documented.\n\n\nDocstring Density & Whitespace Minimization\n-------------------------------------------\n\nOne problem with extensively documented classes & functions, is that\nthere is a lot of screen space wasted on whitespace.  Here's some\ncurrent Enthought code (from lib/cp/fluids/gassmann.py)::\n\n    def max_gas(temperature, pressure, api, specific_gravity=.56):\n        \"\"\"\n        Computes the maximum dissolved gas in oil using Batzle and\n        Wang (1992).\n\n        Parameters\n        ----------\n        temperature : sequence\n            Temperature in degrees Celsius\n        pressure : sequence\n            Pressure in MPa\n        api : sequence\n            Stock tank oil API\n        specific_gravity : sequence\n            Specific gravity of gas at STP, default is .56\n\n        Returns\n        -------\n        max_gor : sequence\n            Maximum dissolved gas in liters/liter\n\n        Description\n        -----------\n        This estimate is based on equations given by Mavko, Mukerji,\n        and Dvorkin, (1998, pp. 218-219, or 2003, p. 236) obtained\n        originally from Batzle and Wang (1992).\n        \"\"\"\n        code...\n\nThe docstring is 24 lines long.\n\nRather than using subsections, field lists (which exist now) can save\n6 lines::\n\n    def max_gas(temperature, pressure, api, specific_gravity=.56):\n        \"\"\"\n        Computes the maximum dissolved gas in oil using Batzle and\n        Wang (1992).\n\n        :Parameters:\n            temperature : sequence\n                Temperature in degrees Celsius\n            pressure : sequence\n                Pressure in MPa\n            api : sequence\n                Stock tank oil API\n            specific_gravity : sequence\n                Specific gravity of gas at STP, default is .56\n        :Returns:\n            max_gor : sequence\n                Maximum dissolved gas in liters/liter\n        :Description: This estimate is based on equations given by\n            Mavko, Mukerji, and Dvorkin, (1998, pp. 218-219, or 2003,\n            p. 236) obtained originally from Batzle and Wang (1992).\n        \"\"\"\n        code...\n\nAs with the \"Description\" field above, field bodies may begin on the\nsame line as the field name, which also saves space.\n\nThe output for field lists is typically a table structure.  For\nexample:\n\n    :Parameters:\n        temperature : sequence\n            Temperature in degrees Celsius\n        pressure : sequence\n            Pressure in MPa\n        api : sequence\n            Stock tank oil API\n        specific_gravity : sequence\n            Specific gravity of gas at STP, default is .56\n    :Returns:\n        max_gor : sequence\n            Maximum dissolved gas in liters/liter\n    :Description:\n        This estimate is based on equations given by Mavko,\n        Mukerji, and Dvorkin, (1998, pp. 218-219, or 2003, p. 236)\n        obtained originally from Batzle and Wang (1992).\n\nBut the definition lists describing the parameters and return values\nare still wasteful of space.  There are a lot of half-filled lines.\n\nDefinition lists are currently defined as::\n\n    term : classifier\n        definition\n\nWhere the classifier part is optional.  Ideas for improvements:\n\n1. We could allow multiple classifiers::\n\n       term : classifier one : two : three ...\n           definition\n\n2. We could allow the definition on the same line as the term, using\n   some embedded/inline markup:\n\n   * \"--\" could be used, but only in limited and well-known contexts::\n\n         term -- definition\n\n     This is the syntax used by StructuredText (one of\n     reStructuredText's predecessors).  It was not adopted for\n     reStructuredText because it is ambiguous -- people often use \"--\"\n     in their text, as I just did.  But given a constrained context,\n     the ambiguity would be acceptable (or would it?).  That context\n     would be: in docstrings, within a field list, perhaps only with\n     certain well-defined field names (parameters, returns).\n\n   * The \"constrained context\" above isn't really enough to make the\n     ambiguity acceptable.  Instead, a slightly more verbose but far\n     less ambiguous syntax is possible::\n\n         term === definition\n\n     This syntax has advantages.  Equals signs lend themselves to the\n     connotation of \"definition\".  And whereas one or two equals signs\n     are commonly used in program code, three equals signs in a row\n     have no conflicting meanings that I know of.  (Update: there\n     *are* uses out there.)\n\n   The problem with this approach is that using inline markup for\n   structure is inherently ambiguous in reStructuredText.  For\n   example, writing *about* definition lists would be difficult::\n\n       ``term === definition`` is an example of a compact definition list item\n\n   The parser checks for structural markup before it does inline\n   markup processing.  But the \"===\" should be protected by its inline\n   literal context.\n\n3. We could allow the definition on the same line as the term, using\n   structural markup.  A variation on bullet lists would work well::\n\n       : term :: definition\n       : another term :: and a definition that\n         wraps across lines\n\n   Some ambiguity remains::\n\n       : term ``containing :: double colons`` :: definition\n\n   But the likelihood of such cases is negligible, and they can be\n   covered in the documentation.\n\n   Other possibilities for the definition delimiter include::\n\n       : term : classifier -- definition\n       : term : classifier --- definition\n       : term : classifier : : definition\n       : term : classifier === definition\n\nThe third idea currently has the best chance of being adopted and\nimplemented.\n\n\nRecommendation\n``````````````\n\nCombining these ideas, the function definition becomes::\n\n    def max_gas(temperature, pressure, api, specific_gravity=.56):\n        \"\"\"\n        Computes the maximum dissolved gas in oil using Batzle and\n        Wang (1992).\n\n        :Parameters:\n            : temperature : sequence :: Temperature in degrees Celsius\n            : pressure : sequence :: Pressure in MPa\n            : api : sequence :: Stock tank oil API\n            : specific_gravity : sequence :: Specific gravity of gas at\n              STP, default is .56\n        :Returns:\n            : max_gor : sequence :: Maximum dissolved gas in liters/liter\n        :Description: This estimate is based on equations given by\n            Mavko, Mukerji, and Dvorkin, (1998, pp. 218-219, or 2003,\n            p. 236) obtained originally from Batzle and Wang (1992).\n        \"\"\"\n        code...\n\nThe docstring is reduced to 14 lines, from the original 24.

Documentation will be generated directly from Python source code,\n   drawing from the code structure, docstrings, and possibly other\n   comments.\n\n2. The tool will extract logical constructs as appropriate, minimizing\n   the need for comments that are redundant with the code structure.\n   The output should reflect both documented and undocumented\n   elements.\n\n\nSource Format\n-------------\n\n1. The docstrings will be formatted in as terse syntax as possible.\n   Required tags, syntax, and white space should be minimized.\n\n2. The tool must support the use of Traits.  Special comment syntax\n   for Traits may be necessary.  Information about the Traits package\n   is available at http://code.enthought.com/traits/.  In the\n   following example, each trait definition is prefaced by a plain\n   comment::\n\n       __traits__ = {\n\n       # The current selection within the frame.\n       'selection' : Trait([], TraitInstance(list)),\n\n       # The frame has been activated or deactivated.\n       'activated' : TraitEvent(),\n\n       'closing' : TraitEvent(),\n\n       # The frame is closed.\n       'closed' : TraitEvent(),\n       }\n\n3. Support for ReStructuredText (ReST) format is desirable, because\n   much of the existing docstrings uses ReST.  However, the complete\n   ReST specification need not be supported, if a subset can achieve\n   the project goals.  If the tool does not support ReST, the\n   contractor should also provide a tool or path to convert existing\n   docstrings.\n\n\nOutput Format\n-------------\n\n1. Documentation will be output as a navigable suite of HTML\n   files.\n\n2. The style of the HTML files will be customizable by a cascading\n   style sheet and/or a customizable template.\n\n3. Page elements such as headers and footer should be customizable, to\n   support differing requirements from one documentation project to\n   the next.\n\n\nOutput Structure and Navigation\n-------------------------------\n\n1. The navigation scheme for the HTML files should not rely on frames,\n   and should harmonize with conversion to Microsoft HTML Help (.chm)\n   format.\n\n2. The output should be structured to make navigable the architecture\n   of the Python code.  Packages, modules, classes, traits, and\n   functions should be presented in clear, logical hierarchies.\n   Diagrams or trees for inheritance, collaboration, sub-packaging,\n   etc. are desirable but not required.\n\n3. The output must include indexes that provide a comprehensive view\n   of all packages, modules, and classes.  These indexes will provide\n   readers with a clear and exhaustive view of the code base.  These\n   indexes should be presented in a way that is easily accessible and\n   allows easy navigation.\n\n4. Cross-references to other documented elements will be used\n   throughout the documentation, to enable the reader to move quickly\n   relevant information.  For example, where type information for an\n   element is available, the type definition should be\n   cross-referenced.\n\n5. The HTML suite should provide consistent navigation back to the\n   home page, which will include the following information:\n\n   * Bibliographic information\n\n     - Author\n     - Copyright\n     - Release date\n     - Version number\n\n   * Abstract\n\n   * References\n\n     - Links to related internal docs (i.e., other docs for the same\n       product)\n\n     - Links to related external docs (e.g., supporting development\n       docs, Python support docs, docs for included packages)\n\n   It should be possible to specify similar information at the top\n   level of each package, so that packages can be included as\n   appropriate for a given application.\n\n\nLicense\n=======\n\nEnthought intends to release the software under an open-source\n(\"BSD-style\") license.\n"

    "content": "==========================\n Docutils_ Hacker's Guide\n==========================\n\n:Author: Lea Wiemann\n:Contact: docutils-develop@lists.sourceforge.net\n:Revision: $Revision$\n:Date: $Date$\n:Copyright: This document has been placed in the public domain.\n\n:Abstract: This is the introduction to Docutils for all persons who\n    want to extend Docutils in some way.\n:Prerequisites: You have used reStructuredText_ and played around with\n    the `Docutils front-end tools`_ before.  Some (basic) Python\n    knowledge is certainly helpful (though not necessary, strictly\n    speaking).\n\n.. _Docutils: https://docutils.sourceforge.io/\n.. _reStructuredText: https://docutils.sourceforge.io/rst.html\n.. _Docutils front-end tools: ../user/tools.html\n\n.. contents::\n\n\nOverview of the Docutils Architecture\n=====================================\n\nTo give you an understanding of the Docutils architecture, we'll dive\nright into the internals using a practical example.\n\nConsider the following reStructuredText file::\n\n    My *favorite* language is Python_.\n\n    .. _Python: https://www.python.org/\n\nUsing the ``rst2html.py`` front-end tool, you would get an HTML output\nwhich looks like this::\n\n    [uninteresting HTML code removed]\n    <body>\n    <div class=\"document\">\n    <p>My <em>favorite</em> language is <a class=\"reference\" href=\"https://www.python.org/\">Python</a>.</p>\n    </div>\n    </body>\n    </html>\n\nWhile this looks very simple, it's enough to illustrate all internal\nprocessing stages of Docutils.  Let's see how this document is\nprocessed from the reStructuredText source to the final HTML output:\n\n\nReading the Document\n--------------------\n\nThe **Reader** reads the document from the source file and passes it\nto the parser (see below).  The default reader is the standalone\nreader (``docutils/readers/standalone.py``) which just reads the input\ndata from a single text file.  Unless you want to do really fancy\nthings, there is no need to change that.\n\nSince you probably won't need to touch readers, we will just move on\nto the next stage:\n\n\nParsing the Document\n--------------------\n\nThe **Parser** analyzes the the input document and creates a **node\ntree** representation.  In this case we are using the\n**reStructuredText parser** (``docutils/parsers/rst/__init__.py``).\nTo see what that node tree looks like, we call ``quicktest.py`` (which\ncan be found in the ``tools/`` directory of the Docutils distribution)\nwith our example file (``test.txt``) as first parameter (Windows users\nmight need to type ``python quicktest.py test.txt``)::\n\n    $ quicktest.py test.txt\n    <document source=\"test.txt\">\n        <paragraph>\n            My\n            <emphasis>\n                favorite\n             language is\n            <reference name=\"Python\" refname=\"python\">\n                Python\n            .\n        <target ids=\"python\" names=\"python\" refuri=\"https://www.python.org/\">\n\nLet us now examine the node tree:\n\nThe top-level node is ``document``.  It has a ``source`` attribute\nwhose value is ``text.txt``.  There are two children: A ``paragraph``\nnode and a ``target`` node.  The ``paragraph`` in turn has children: A\ntext node (\"My \"), an ``emphasis`` node, a text node (\" language is \"),\na ``reference`` node, and again a ``Text`` node (\".\").\n\nThese node types (``document``, ``paragraph``, ``emphasis``, etc.) are\nall defined in ``docutils/nodes.py``.  The node types are internally\narranged as a class hierarchy (for example, both ``emphasis`` and\n``reference`` have the common superclass ``Inline``).  To get an\noverview of the node class hierarchy, use epydoc (type ``epydoc\nnodes.py``) and look at the class hierarchy tree.\n\n\nTransforming the Document\n-------------------------\n\nIn the node tree above, the ``reference`` node does not contain the\ntarget URI (``https://www.python.org/``) yet.\n\nAssigning the target URI (from the ``target`` node) to the\n``reference`` node is *not* done by the parser (the parser only\ntranslates the input document into a node tree).\n\nInstead, it's done by a **Transform**.  In this case (resolving a\nreference), it's done by the ``ExternalTargets`` transform in\n``docutils/transforms/references.py``.\n\nIn fact, there are quite a lot of Transforms, which do various useful\nthings like creating the table of contents, applying substitution\nreferences or resolving auto-numbered footnotes.\n\nThe Transforms are applied after parsing.  To see how the node tree\nhas changed after applying the Transforms, we use the\n``rst2pseudoxml.py`` tool:\n\n.. parsed-literal::\n\n    $ rst2pseudoxml.py test.txt\n    <document source=\"test.txt\">\n        <paragraph>\n            My\n            <emphasis>\n                favorite\n             language is\n            <reference name=\"Python\" **refuri=\"https://www.python.org/\"**>\n                Python\n            .\n        <target ids=\"python\" names=\"python\" ``refuri=\"https://www.python.org/\"``>\n\nFor our small test document, the only change is that the ``refname``\nattribute of the reference has been replaced by a ``refuri``\nattribute |---| the reference has been resolved.\n\nWhile this does not look very exciting, transforms are a powerful tool\nto apply any kind of transformation on the node tree.\n\nBy the way, you can also get a \"real\" XML representation of the node\ntree by using ``rst2xml.py`` instead of ``rst2pseudoxml.py``.\n\n\nWriting the Document\n--------------------\n\nTo get an HTML document out of the node tree, we use a **Writer**, the\nHTML writer in this case (``docutils/writers/html4css1.py``).\n\nThe writer receives the node tree and returns the output document.\nFor HTML output, we can test this using the ``rst2html.py`` tool::\n\n    $ rst2html.py --link-stylesheet test.txt\n    <?xml version=\"1.0\" encoding=\"utf-8\" ?>\n    <!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">\n    <html xmlns=\"https://www.w3.org/1999/xhtml\" xml:lang=\"en\" lang=\"en\">\n    <head>\n    <meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n    <meta name=\"generator\" content=\"Docutils 0.3.10: https://docutils.sourceforge.io/\" />\n    <title></title>\n    <link rel=\"stylesheet\" href=\"../docutils/writers/html4css1/html4css1.css\" type=\"text/css\" />\n    </head>\n    <body>\n    <div class=\"document\">\n    <p>My <em>favorite</em> language is <a class=\"reference\" href=\"https://www.python.org/\">Python</a>.</p>\n    </div>\n    </body>\n    </html>\n\nSo here we finally have our HTML output.  The actual document contents\nare in the fourth-last line.  Note, by the way, that the HTML writer\ndid not render the (invisible) ``target`` node |---| only the\n``paragraph`` node and its children appear in the HTML output.\n\n\nExtending Docutils\n==================\n\nNow you'll ask, \"how do I actually extend Docutils?\"\n\nFirst of all, once you are clear about *what* you want to achieve, you\nhave to decide *where* to implement it |---| in the Parser (e.g. by\nadding a directive or role to the reStructuredText parser), as a\nTransform, or in the Writer.  There is often one obvious choice among\nthose three (Parser, Transform, Writer).  If you are unsure, ask on\nthe Docutils-develop_ mailing list.\n\nIn order to find out how to start, it is often helpful to look at\nsimilar features which are already implemented.  For example, if you\nwant to add a new directive to the reStructuredText parser, look at\nthe implementation of a similar directive in\n``docutils/parsers/rst/directives/``.\n\n\nModifying the Document Tree Before It Is Written\n------------------------------------------------\n\nYou can modify the document tree right before the writer is called.\nOne possibility is to use the publish_doctree_ and\npublish_from_doctree_ functions.\n\nTo retrieve the document tree, call::\n\n    document = docutils.core.publish_doctree(...)\n\nPlease see the docstring of publish_doctree for a list of parameters.\n\n.. XXX Need to write a well-readable list of (commonly used) options\n   of the publish_* functions.  Probably in api/publisher.txt.\n\n``document`` is the root node of the document tree.  You can now\nchange the document by accessing the ``document`` node and its\nchildren |---| see `The Node Interface`_ below.\n\nWhen you're done with modifying the document tree, you can write it\nout by calling::\n\n    output = docutils.core.publish_from_doctree(document, ...)\n\n.. _publish_doctree: ../api/publisher.html#publish_doctree\n.. _publish_from_doctree: ../api/publisher.html#publish_from_doctree\n\n\nThe Node Interface\n------------------\n\nAs described in the overview above, Docutils' internal representation\nof a document is a tree of nodes.  We'll now have a look at the\ninterface of these nodes.\n\n(To be completed.)\n\n\nWhat Now?\n=========\n\nThis document is not complete.  Many topics could (and should) be\ncovered here.  To find out with which topics we should write about\nfirst, we are awaiting *your* feedback.  So please ask your questions\non the Docutils-develop_ mailing list.\n\n\n.. _Docutils-develop: ../user/mailing-lists.html#docutils-develop\n\n\n.. |---| unicode:: 8212 .. em-dash\n   :trim:\n\n\f\n..\n   Local Variables:\n   mode: indented-text\n   indent-tabs-mode: nil\n   sentence-end-double-space: t\n   fill-column: 70\n   End:\n"

A few quotes sum up the policies of\nthe Docutils project.  The IETF's classic credo (by MIT professor Dave\nClark) is an ideal we can aspire to:\n\n    We reject: kings, presidents, and voting.  We believe in: rough\n    consensus and running code.\n\nAs architect, chief cook and bottle-washer, David Goodger currently\nfunctions as BDFN (Benevolent Dictator For Now).  (But he would\nhappily abdicate the throne given a suitable candidate.  Any takers?)\n\nEric S. Raymond, anthropologist of the hacker subculture, writes in\nhis essay `The Magic Cauldron`_:\n\n    The number of contributors [to] projects is strongly and inversely\n    correlated with the number of hoops each project makes a user go\n    through to contribute.\n\nWe will endeavour to keep the barrier to entry as low as possible.\nThe policies below should not be thought of as barriers, but merely as\na codification of experience to date.  These are \"best practices\";\nguidelines, not absolutes.  Exceptions are expected, tolerated, and\nused as a source of improvement.  Feedback and criticism is welcome.\n\nAs for control issues, Emmett Plant (CEO of the Xiph.org Foundation,\noriginators of Ogg Vorbis) put it well when he said:\n\n    Open source dictates that you lose a certain amount of control\n    over your codebase, and that's okay with us.\n\n.. [#bcs] Phrase borrowed from `Ben Collins-Sussman of the Subversion\n   project <http://www.red-bean.com/sussman/svn-anti-fud.html>`__.\n\n.. _The Magic Cauldron:\n   http://www.catb.org/~esr/writings/magic-cauldron/\n\n\nPython Coding Conventions\n=========================\n\nContributed code will not be refused merely because it does not\nstrictly adhere to these conditions; as long as it's internally\nconsistent, clean, and correct, it probably will be accepted.  But\ndon't be surprised if the \"offending\" code gets fiddled over time to\nconform to these conventions.\n\nThe Docutils project shall follow the generic coding conventions as\nspecified in the `Style Guide for Python Code`_ and `Docstring\nConventions`_ PEPs, summarized, clarified, and extended as follows:\n\n* 4 spaces per indentation level.  No hard tabs.\n\n* Use only 7-bit ASCII, no 8-bit strings.  See `Docutils\n  Internationalization`_.\n\n* No one-liner compound statements (i.e., no ``if x: return``: use two\n  lines & indentation), except for degenerate class or method\n  definitions (i.e., ``class X: pass`` is OK.).\n\n* Lines should be no more than 78 characters long.\n\n* Use \"StudlyCaps\" for class names (except for element classes in\n  docutils.nodes).\n\n* Use \"lowercase\" or \"lowercase_with_underscores\" for function,\n  method, and variable names.  For short names, maximum two words,\n  joined lowercase may be used (e.g. \"tagname\").  For long names with\n  three or more words, or where it's hard to parse the split between\n  two words, use lowercase_with_underscores (e.g.,\n  \"note_explicit_target\", \"explicit_target\").  If in doubt, use\n  underscores.\n\n* Avoid lambda expressions, which are inherently difficult to\n  understand.  Named functions are preferable and superior: they're\n  faster (no run-time compilation), and well-chosen names serve to\n  document and aid understanding.\n\n* Avoid functional constructs (filter, map, etc.).  Use list\n  comprehensions instead.\n\n* Avoid ``from __future__ import`` constructs.  They are inappropriate\n  for production code.\n\n* Use 'single quotes' for string literals, and \"\"\"triple double\n  quotes\"\"\" for docstrings.\n\n.. _Style Guide for Python Code:\n   https://peps.python.org/pep-0008\n.. _Docstring Conventions: https://peps.python.org/pep-0257\n.. _Docutils Internationalization: ../howto/i18n.html#python-code\n\n\nDocumentation Conventions\n=========================\n\n* Docutils documentation is written using reStructuredText, of course.\n\n* Use 7-bit ASCII if at all possible, and Unicode substitutions when\n  necessary.\n\n* Use the following section title adornment styles::\n\n      ================\n       Document Title\n      ================\n\n      --------------------------------------------\n       Document Subtitle, or Major Division Title\n      --------------------------------------------\n\n      Section\n      =======\n\n      Subsection\n      ----------\n\n      Sub-Subsection\n      ``````````````\n\n      Sub-Sub-Subsection\n      ..................\n\n* Use two blank lines before each section/subsection/etc. title.  One\n  blank line is sufficient between immediately adjacent titles.\n\n* Add a bibliographic field list immediately after the document\n  title/subtitle.  See the beginning of this document for an example.\n\n* Add an Emacs \"local variables\" block in a comment at the end of the\n  document.  See the end of this document for an example.\n\n\nCopyrights and Licensing\n========================\n\nThe majority of the Docutils project code and documentation has been\nplaced in the public domain (see `Copying Docutils`_).\n\nUnless clearly and explicitly indicated\notherwise, any patches (modifications to existing files) submitted to\nthe project for inclusion (via Subversion, SourceForge trackers,\nmailing lists, or private email) are assumed to be in the public\ndomain as well.\n\nAny new files contributed to the project should clearly state their\nintentions regarding copyright, in one of the following ways:\n\n* Public domain (preferred): include the statement \"This\n  module/document has been placed in the public domain.\"\n\n* Copyright & open source license: include a copyright notice, along\n  with either an embedded license statement, a reference to an\n  accompanying license file, or a license URL.\n\n  The license should be well known, simple and compatible with other\n  open source software licenses. To keep the number of different\n  licenses at a minimum, using the `2-Clause BSD license`_\n  (`local copy`__) is recommended.\n\n  ..

Anyone can access the\nrepository anonymously.  Only project developers can make changes.\n(If you would like to become a project developer, just ask!)  Also see\n`Setting Up For Docutils Development`_ below for some useful info.\n\nUnless you really *really* know what you're doing, please do *not* use\n``svn import``.  It's quite easy to mess up the repository with an\nimport.\n\n.. _repository documentation: repository.html\n\n\nBranches\n--------\n\n(These branch policies go into effect with Docutils 0.4.)\n\nThe \"docutils\" directory of the **trunk** (a.k.a. the **Docutils\ncore**) is used for active -- but stable, fully tested, and reviewed\n-- development.\n\nIf we need to cut a bugfix release, we'll create a **maintenance branch**\nbased on the latest feature release.  For example, when Docutils 0.5 is\nreleased, this would be ``branches/docutils-0.5``, and any existing 0.4.x\nmaintenance branches may be retired.  Maintenance branches will receive bug\nfixes only; no new features will be allowed here.\n\nObvious and uncontroversial bug fixes *with tests* can be checked in\ndirectly to the core and to the maintenance branches.  Don't forget to\nadd test cases!  Many (but not all) bug fixes will be applicable both\nto the core and to the maintenance branches; these should be applied\nto both.  No patches or dedicated branches are required for bug fixes,\nbut they may be used.  It is up to the discretion of project\ndevelopers to decide which mechanism to use for each case.\n\n.. _feature branches:\n.. _feature branch:\n\nFeature additions and API changes will be done in **feature\nbranches**.  Feature branches will not be managed in any way.\nFrequent small check-ins are encouraged here.  Feature branches must be\ndiscussed on the `docutils-develop mailing list`_ and reviewed before\nbeing merged into the core.\n\n.. _docutils-develop mailing list:\n   https://lists.sourceforge.net/lists/listinfo/docutils-develop\n\n\nReview Criteria\n```````````````\n\nBefore a new feature, an API change, or a complex, disruptive, or\ncontroversial bug fix can be checked in to the core or into a\nmaintenance branch, it must undergo review.  These are the criteria:\n\n* The branch must be complete, and include full documentation and\n  tests.\n\n* There should ideally be one branch merge commit per feature or\n  change.  In other words, each branch merge should represent a\n  coherent change set.\n\n* The code must be stable and uncontroversial.  Moving targets and\n  features under debate are not ready to be merged.\n\n* The code must work.  The test suite must complete with no failures.\n  See `Docutils Testing`_.\n\nThe review process will ensure that at least one other set of eyeballs\n& brains sees the code before it enters the core.  In addition to the\nabove, the general `Check-ins`_ policy (below) also applies.\n\n.. _Docutils testing: testing.html\n\n\nCheck-ins\n---------\n\nChanges or additions to the Docutils core and maintenance branches\ncarry a commitment to the Docutils user community.  Developers must be\nprepared to fix and maintain any code they have committed.\n\nThe Docutils core (``trunk/docutils`` directory) and maintenance\nbranches should always be kept in a stable state (usable and as\nproblem-free as possible).  All changes to the Docutils core or\nmaintenance branches must be in `good shape`_, usable_, documented_,\ntested_, and `reasonably complete`_. Starting with version 1.0, they must\nalso comply with the `backwards compatibility policy`_.\n\n* _`Good shape` means that the code is clean, readable, and free of\n  junk code (unused legacy code; by analogy to \"junk DNA\").\n\n* _`Usable` means that the code does what it claims to do.  An \"XYZ\n  Writer\" should produce reasonable XYZ output.\n\n* _`Documented`: The more complete the documentation the better.\n  Modules & files must be at least minimally documented internally.\n  `Docutils Front-End Tools`_ should have a new section for any\n  front-end tool that is added.  `Docutils Configuration Files`_\n  should be modified with any settings/options defined.  For any\n  non-trivial change, the HISTORY.txt_ file should be updated.\n\n* _`Tested` means that unit and/or functional tests, that catch all\n  bugs fixed and/or cover all new functionality, have been added to\n  the test suite.  These tests must be checked by running the test\n  suite under all supported Python versions, and the entire test suite\n  must pass.  See `Docutils Testing`_.\n\n* _`Reasonably complete` means that the code must handle all input.\n  Here \"handle\" means that no input can cause the code to fail (cause\n  an exception, or silently and incorrectly produce nothing).\n  \"Reasonably complete\" does not mean \"finished\" (no work left to be\n  done).  For example, a writer must handle every standard element\n  from the Docutils document model; for unimplemented elements, it\n  must *at the very least* warn that \"Output for element X is not yet\n  implemented in writer Y\".\n\nIf you really want to check code directly into the Docutils core,\nyou can, but you must ensure that it fulfills the above criteria\nfirst.  People will start to use it and they will expect it to work!\nIf there are any issues with your code, or if you only have time for\ngradual development, you should put it on a branch or in the sandbox\nfirst.  It's easy to move code over to the Docutils core once it's\ncomplete.\n\nIt is the responsibility and obligation of all developers to keep the\nDocutils core and maintenance branches stable.  If a commit is made to\nthe core or maintenance branch which breaks any test, the solution is\nsimply to revert the change.  This is not vindictive; it's practical.\nWe revert first, and discuss later.\n\nDocutils will pursue an open and trusting policy for as long as\npossible, and deal with any aberrations if (and hopefully not when)\nthey happen.  We'd rather see a torrent of loose contributions than\njust a trickle of perfect-as-they-stand changes.  The occasional\nmistake is easy to fix.  That's what version control is for!\n\n.. _Docutils Front-End Tools: ../user/tools.html\n.. _Docutils Configuration Files: ../user/config.html\n.. _HISTORY.txt: ../../HISTORY.txt\n\n\n.. _`Version Numbering`:\n\nVersion Identification\n======================\n\nThe state of development of the current Docutils codebase is stored in\ntwo forms: the sequence `docutils.__version_info__`_ and the\n`PEP 440`_ conformant text string `docutils.__version__`_.\nSee also the `Docutils Release Procedure`_\n\n.. _Docutils Release Procedure: release.html#version-numbers\n\n\n``docutils.__version_info__``\n-----------------------------\n\n``docutils.__version_info__`` is an instance of ``docutils.VersionInfo``\nbased on collections.namedtuple_. It is modelled on `sys.version_info`_\nand has the following attributes:\n\nmajor : non-negative integer\n    **Major releases** (x.0, e.g. 1.0) will be rare, and will\n    represent major changes in API, functionality, or commitment.  The\n    major number will be bumped to 1 when the project is\n    feature-complete, and may be incremented later if there is a major\n    change in the design or API.  When Docutils reaches version 1.0,\n    the major APIs will be considered frozen.\n    For details, see the `backwards compatibility policy`_.\n\nminor : non-negative integer\n    Releases that change the minor number (x.y, e.g. 0.5) will be\n    **feature releases**; new features from the `Docutils core`_ will\n    be included.\n\nmicro : non-negative integer\n    Releases that change the micro number (x.y.z, e.g. 0.4.1) will be\n    **bug-fix releases**.

Otherwise, use a PendingDeprecationWarning_.\n\nChanges that may affect end-users (e.g. by requiring changes to the\nconfiguration file or potentially breaking custom style sheets) should be\nannounced with a FutureWarning_.\n\n.. _backwards compatibility rules:\n   https://peps.python.org/pep-0387/#backwards-compatibility-rules\n.. _making incompatible changes:\n   https://peps.python.org/pep-0387/#making-incompatible-changes\n.. _Sphinx: https://www.sphinx-doc.org/\n.. _DeprecationWarning:\n   https://docs.python.org/3/library/exceptions.html#DeprecationWarning\n.. _PendingDeprecationWarning:\n   https://docs.python.org/3/library/exceptions.html#PendingDeprecationWarning\n.. _FutureWarning:\n   https://docs.python.org/3/library/exceptions.html#FutureWarning\n\n\nSnapshots\n=========\n\nSnapshot tarballs can be downloaded from the repository (see the \"download\nsnapshot\" button in the head of the code listing table).\n\n* the `Docutils core`_, representing the current cutting-edge state of\n  development;\n\n* the `sandbox directory`_ with contributed projects and extensions from\n  `the Sandbox`_;\n\n.. * maintenance branches, for bug fixes;\n\n   TODO: do we have active maintenance branches?\n   (the only branch looking like a maintenance branch is\n   https://sourceforge.net/p/docutils/code/HEAD/tree/branches/docutils-0.4)\n\n* `development branches`_, representing ongoing development efforts to bring\n  new features into Docutils.\n\n.. _Docutils core:\n   https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils\n.. _development branches:\n   https://sourceforge.net/p/docutils/code/HEAD/tree/branches/\n\n\nSetting Up For Docutils Development\n===================================\n\nWhen making changes to the code, testing_ is a must.  The code should\nbe run to verify that it produces the expected results, and the entire\ntest suite should be run too.  The modified Docutils code has to be\naccessible to Python for the tests to have any meaning.\nSee `editable installs`_ for ways to keep the Docutils code\naccessible during development.\n\n.. _testing: tested_\n.. _editable installs: repository.html#editable-installs\n\n\nMailing Lists\n=============\n\nDevelopers are recommended to subscribe to all `Docutils mailing\nlists`_.\n\n.. _Docutils mailing lists: ../user/mailing-lists.html\n\n\nThe Wiki\n========\n\nThere is a development wiki at http://docutils.python-hosting.com/ as\na scratchpad for transient notes.  Please use the repository for\npermanent document storage.\n\nExtensions and Related Projects\n===============================\n\nThe Sandbox\n-----------\n\nThe `sandbox directory`_ is a place to play around, to try out and\nshare ideas.  It's a part of the Subversion repository but it isn't\ndistributed as part of Docutils releases.  Feel free to check in code\nto the sandbox; that way people can try it out but you won't have to\nworry about it working 100% error-free, as is the goal of the Docutils\ncore.  A project-specific subdirectory should be created for each new\nproject.  Any developer who wants to play in the sandbox may do so,\nbut project directories are recommended over personal directories,\nwhich discourage collaboration.  It's OK to make a mess in the\nsandbox!  But please, play nice.\n\nPlease update the `sandbox README`_ file with links and a brief\ndescription of your work.\n\nIn order to minimize the work necessary for others to install and try\nout new, experimental components, the following sandbox directory\nstructure is recommended::\n\n    sandbox/\n        project_name/ # For a collaborative project.\n            README.txt  # Describe the requirements, purpose/goals, usage,\n                        # and list the maintainers.\n            docs/\n                ...\n            component.py    # The component is a single module.\n                            # *OR* (but *not* both)\n            component/      # The component is a package.\n                __init__.py  # Contains the Reader/Writer class.\n                other1.py    # Other modules and data files used\n                data.txt     # by this component.\n                ...\n            test/       # Test suite.\n                ...\n            tools/      # For front ends etc.\n                ...\n            setup.py    # Install the component code and tools/ files\n                        # into the right places.\n        userid/       # For *temporary* personal space.\n\nSome sandbox projects are destined to move to the Docutils core once\ncompleted.  Others, such as add-ons to Docutils or applications of\nDocutils, may graduate to become `parallel projects`_.\n\n.. _sandbox README: https://docutils.sourceforge.io/sandbox/README.html\n.. _sandbox directory:\n   https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/sandbox/\n\n\n.. _parallel project:\n\nParallel Projects\n-----------------\n\nParallel projects contain useful code that is not central to the\nfunctioning of Docutils.  Examples are specialized add-ons or\nplug-ins, and applications of Docutils.  They use Docutils, but\nDocutils does not require their presence to function.\n\nAn official parallel project will have its own directory beside (or\nparallel to) the main ``docutils`` directory in the Subversion\nrepository.  It can have its own web page in the\ndocutils.sourceforge.io domain, its own file releases and\ndownloadable snapshots, and even a mailing list if that proves useful.\nHowever, an official parallel project has implications: it is expected\nto be maintained and continue to work with changes to the core\nDocutils.\n\nA parallel project requires a project leader, who must commit to\ncoordinate and maintain the implementation:\n\n* Answer questions from users and developers.\n* Review suggestions, bug reports, and patches.\n* Monitor changes and ensure the quality of the code and\n  documentation.\n* Coordinate with Docutils to ensure interoperability.\n* Put together official project releases.\n\nOf course, related projects may be created independently of Docutils.\nThe advantage of a parallel project is that the SourceForge\nenvironment and the developer and user communities are already\nestablished.  Core Docutils developers are available for consultation\nand may contribute to the parallel project.  It's easier to keep the\nprojects in sync when there are changes made to the core Docutils\ncode.\n\nOther related projects\n----------------------\n\nMany related but independent projects are listed in the Docutils\n`link list`_. If you want your project to appear there, drop a note at\nthe Docutils-develop_ mailing list.\n\n.. _link list: https://docutils.sourceforge.io/docs/user/links.html\n.. _docutils-develop: docs/user/mailing-lists.html#docutils-develop\n\n\f\n..\n   Local Variables:\n   mode: indented-text\n   indent-tabs-mode: nil\n   sentence-end-double-space: t\n   fill-column: 70\n   End:\n"

Descriptions below list\n'DTD elements' (XML 'generic identifiers' or tag names) corresponding\nto syntax constructs.\n\n\n.. contents::\n\n\nModel\n=====\n\nThe Python Source Reader (\"PySource\") model that's evolving in my mind\ngoes something like this:\n\n1. Extract the docstring/namespace [#]_ tree from the module(s) and/or\n   package(s).\n\n   .. [#] See `Docstring Extractor`_ below.\n\n2. Run the parser on each docstring in turn, producing a forest of\n   doctrees (per nodes.py).\n\n3. Join the docstring trees together into a single tree, running\n   transforms:\n\n   - merge hyperlinks\n   - merge namespaces\n   - create various sections like \"Module Attributes\", \"Functions\",\n     \"Classes\", \"Class Attributes\", etc.; see pysource.dtd_\n   - convert the above special sections to ordinary doctree nodes\n\n4. Run transforms on the combined doctree.  Examples: resolving\n   cross-references/hyperlinks (including interpreted text on Python\n   identifiers); footnote auto-numbering; first field list ->\n   bibliographic elements.\n\n   (Or should step 4's transforms come before step 3?)\n\n5. Pass the resulting unified tree to the writer/builder.\n\nI've had trouble reconciling the roles of input parser and output\nwriter with the idea of modes (\"readers\" or \"directors\").  Does the\nmode govern the transformation of the input, the output, or both?\nPerhaps the mode should be split into two.\n\nFor example, say the source of our input is a Python module.  Our\n\"input mode\" should be the \"Python Source Reader\".  It discovers (from\n``__docformat__``) that the input parser is \"reStructuredText\".  If we\nwant HTML, we'll specify the \"HTML\" output formatter.  But there's a\npiece missing.  What *kind* or *style* of HTML output do we want?\nPyDoc-style, LibRefMan style, etc.  (many people will want to specify\nand control their own style).  Is the output style specific to a\nparticular output format (XML, HTML, etc.)?  Is the style specific to\nthe input mode?  Or can/should they be independent?\n\nI envision interaction between the input parser, an \"input mode\" , and\nthe output formatter.  The same intermediate data format would be used\nbetween each of these, being transformed as it progresses.\n\n\nDocstring Extractor\n===================\n\nWe need code that scans a parsed Python module, and returns an ordered\ntree containing the names, docstrings (including attribute and\nadditional docstrings), and additional info (in parentheses below) of\nall of the following objects:\n\n- packages\n- modules\n- module attributes (+ values)\n- classes (+ inheritance)\n- class attributes (+ values)\n- instance attributes (+ values)\n- methods (+ formal parameters & defaults)\n- functions (+ formal parameters & defaults)\n\n(Extract comments too?  For example, comments at the start of a module\nwould be a good place for bibliographic field lists.)\n\nIn order to evaluate interpreted text cross-references, namespaces for\neach of the above will also be required.\n\nSee python-dev/docstring-develop thread \"AST mining\", started on\n2001-08-14.\n\n\nInterpreted Text\n================\n\nDTD elements: package, module, class, method, function,\nmodule_attribute, class_attribute, instance_attribute, variable,\nparameter, type, exception_class, warning_class.\n\nTo classify identifiers explicitly, the role is given along with the\nidentifier in either prefix or suffix form::\n\n    Use :method:`Keeper.storedata` to store the object's data in\n    `Keeper.data`:instance_attribute:.\n\nThe role may be one of 'package', 'module', 'class', 'method',\n'function', 'module_attribute', 'class_attribute',\n'instance_attribute', 'variable', 'parameter', 'type',\n'exception_class', 'exception', 'warning_class', or 'warning'.

[#github-mirrors] There are also 3rd-party mirrors and forks at\n   GitHub, some of them orphaned. At the time of this writing (2021-11-03),\n   https://github.com/live-clones/docutils/tree/master/docutils\n   provides an hourly updated clone.\n\nRepository Access Methods\n-------------------------\n\nTo get a checkout, first determine the root of the repository depending\non your preferred protocol:\n\nanonymous access: (read only)\n    Subversion_: ``https://svn.code.sf.net/p/docutils/code``\n\n    Git_: ``git://repo.or.cz/docutils.git``\n\n`developer access`_: (read and write)\n    ``svn+ssh://<USERNAME>@svn.code.sf.net/p/docutils/code``\n\nChecking Out the Repository\n---------------------------\n\n.. _creating a local Git clone:\n\nGit_ users can clone a mirror of the docutils repository with ::\n\n      git clone git://repo.or.cz/docutils.git\n\nand proceed according to the `Git documentation`_.\nDeveloper access (read and write) is possible with `git svn`_.\n\n.. _Git documentation: https://git.wiki.kernel.org/index.php/GitDocumentation\n.. _git svn: https://git.wiki.kernel.org/index.php/Git-svn\n\nSubversion_ users can use the following commands\n(substitute your preferred repository root for ROOT):\n\n* To check out only the current main source tree of Docutils, type ::\n\n    svn checkout ROOT/trunk/docutils\n\n* To check out everything (main tree, sandboxes, web site, and parallel\n  projects), type ::\n\n    svn checkout ROOT/trunk docutils\n\n  This will create a working copy of the whole trunk in a new directory\n  called ``docutils``.\n\nNote that you probably do *not* want to check out the ROOT itself\n(without \"/trunk\"), because then you'd end up fetching the whole\nDocutils tree for every branch and tag over and over again.\n\nTo update your working copy later on, ``cd`` into the working copy and\ntype ::\n\n    svn update\n\nSwitching the Repository Root\n-----------------------------\n\nIf you changed your mind and want to use a different repository root,\n``cd`` into your working copy and type::\n\n    svn switch --relocate OLDROOT NEWROOT\n\n\nEditable installs\n=================\n\nThere are several ways to ensure that edits to the Docutils code are\npicked up by Python.\nWe'll assume that the Docutils \"trunk\" is checked out under the\n``~/projects/`` directory.\n\n1. Do an `editable install`__ with pip_::\n\n     python3 -m pip install -e ~/projects/docutils/docutils\n\n   __ https://pip.pypa.io/en/stable/cli/pip_install/#editable-installs\n\n2. Install in `development mode`__ with setuptools_.\n\n   __ https://setuptools.pypa.io/en/latest/userguide/development_mode.html\n      #development-mode\n\n   .. _install manually:\n\n3. Install \"manually\".\n\n   Ensure that the \"docutils\" package is in ``sys.path`` by\n   one of the following actions:\n\n   * Set the ``PYTHONPATH`` environment variable so that Python\n     picks up your local working copy of the code.\n\n     For the bash shell, add this to your ``~/.profile``::\n\n         PYTHONPATH=$HOME/projects/docutils/docutils\n         export PYTHONPATH\n\n     The first line points to the directory containing the ``docutils``\n     package.  The second line exports the environment variable.\n\n   * Create a symlink to the docutils package directory somewhere in the\n     module search path (``sys.path``), e.g., ::\n\n         ln -s ~/projects/docutils/docutils \\\n               /usr/local/lib/python3.9/dist-packages/\n\n   * Use a `path configuration file`__.\n\n     __ https://docs.python.org/library/site.html\n\n   Optionally, add some or all `front-end tools`_\n   to the binary search path, e.g.,\n   add the ``tools`` directory to the ``PATH`` variable::\n\n         PATH=$PATH:$HOME/projects/docutils/docutils/tools\n         export PATH\n\n   or link idividual front-end tools to a suitable place\n   in the binary path::\n\n         ln -s ~/projects/docutils/docutils/tools/docutils-cli.py \\\n               /usr/local/bin/docutils\n\n5. Reinstall Docutils after any change::\n\n       python3 setup.py install\n\n   .. CAUTION::\n\n      This method is **not** recommended for day-to-day development;\n      it's too easy to forget.  Confusion inevitably ensues.\n\n      If you install Docutils this way, Python will always pick up the\n      last-installed copy of the code.  If you ever forget to\n      reinstall the \"docutils\" package, Python won't see your latest\n      changes.\n\nA useful addition to the ``docutils`` top-level directory in branches\nand alternate copies of the code is a ``set-PATHS`` file\ncontaining the following lines::\n\n    # source this file\n    export PYTHONPATH=$PWD:$PWD\n    export PATH=$PWD/tools:$PATH\n\nOpen a shell for this branch, ``cd`` to the ``docutils`` top-level\ndirectory, and \"source\" this file.  For example, using the bash\nshell::\n\n    $ cd some-branch/docutils\n    $ . set-PATHS\n\n.. _pip: https://pypi.org/project/pip/\n.. _setuptools: https://pypi.org/project/setuptools/\n.. _front-end tools: ../user/tools.html\n\n\n.. _developer access:\n\nInformation for Developers\n==========================\n\nIf you would like to have write access to the repository, register\nwith SourceForge.net_ and send your SourceForge.net\nuser names to docutils-develop@lists.sourceforge.net.\n(Note that there may be a delay of several hours until you can commit\nchanges to the repository.)\n\nSourceforge SVN access is documented `here`__\n\n__ https://sourceforge.net/p/forge/documentation/svn/\n\n\nEnsure any changes comply with the `Docutils Project Policies`_\nbefore `checking in`_,\n\n.. _Docutils Project Policies: policies.html\n.. _checking in: policies.html#check-ins\n\n\nSetting Up Your Subversion Client For Development\n-------------------------------------------------\n\nBefore committing changes to the repository, please ensure that the\nfollowing lines are contained (and uncommented) in your local\n~/.subversion/config file, so that new files are added with the\ncorrect properties set::\n\n    [miscellany]\n    # For your convenience:\n    global-ignores = ... *.pyc ...\n    # For correct properties:\n    enable-auto-props = yes\n\n    [auto-props]\n    *.py = svn:eol-style=native;svn:keywords=Author Date Id Revision\n    *.txt = svn:eol-style=native;svn:keywords=Author Date Id Revision\n    *.html = svn:eol-style=native;svn:keywords=Author Date Id Revision\n    *.xml = svn:eol-style=native;svn:keywords=Author Date Id Revision\n    *.tex = svn:eol-style=native;svn:keywords=Author Date Id Revision\n    *.css = svn:eol-style=native;svn:keywords=Author Date Id Revision\n    *.patch = svn:eol-style=native\n    *.sh = svn:eol-style=native;svn:executable;svn:keywords=Author Date Id Revision\n    *.png = svn:mime-type=image/png\n    *.jpg = svn:mime-type=image/jpeg\n    *.gif = svn:mime-type=image/gif\n\n\nRepository Layout\n=================\n\nThe following tree shows the repository layout::\n\n    docutils/\n    |-- branches/\n    |   |-- branch1/\n    |   |   |-- docutils/\n    |   |   |-- sandbox/\n    |   |   `-- web/\n    |   `-- branch2/\n    |       |-- docutils/\n    |       |-- sandbox/\n    |       `-- web/\n    |-- tags/\n    |   |-- tag1/\n    |   |   |-- docutils/\n    |   |   |-- sandbox/\n    |   |   `-- web/\n    |   `-- tag2/\n    |       |-- docutils/\n    |       |-- sandbox/\n    |       `-- web/\n    `-- trunk/\n        |-- docutils/\n        |-- sandbox/\n        `-- web/\n\nThe main source tree lives at ``docutils/trunk/docutils/``, next to\nthe sandboxes (``docutils/trunk/sandbox/``) and the web site files\n(``docutils/trunk/web/``).\n\n``docutils/branches/`` and ``docutils/tags/`` contain (shallow) copies\nof either the whole trunk or only the main source tree\n(``docutils/trunk/docutils``).\n"

Unadorned RFC822_ everywhere::\n\n       Author: Me\n       Version: 1\n\n   Advantages: clean, precedent (RFC822-compliant).  Disadvantage:\n   ambiguous (these paragraphs are a prime example).\n\n   Conclusion: rejected.\n\n2. Special case: use unadorned RFC822_ for the very first or very last\n   text block of a document::\n\n       \"\"\"\n       Author: Me\n       Version: 1\n\n       The rest of the document...\n       \"\"\"\n\n   Advantages: clean, precedent (RFC822-compliant).  Disadvantages:\n   special case, flat (unnested) field lists only, still ambiguous::\n\n       \"\"\"\n       Usage: cmdname [options] arg1 arg2 ...\n\n       We obviously *don't* want the like above to be interpreted as a\n       field list item.  Or do we?\n       \"\"\"\n\n   Conclusion: rejected for the general case, accepted for specific\n   contexts (PEPs, email).\n\n3. Use a directive::\n\n       .. fields::\n\n          Author: Me\n          Version: 1\n\n   Advantages: explicit and unambiguous, RFC822-compliant.\n   Disadvantage: cumbersome.\n\n   Conclusion: rejected for the general case (but such a directive\n   could certainly be written).\n\n4. Use Javadoc-style::\n\n       @Author: Me\n       @Version: 1\n       @param a: integer\n\n   Advantages: unambiguous, precedent, flexible.  Disadvantages:\n   non-intuitive, ugly, not RFC822-compliant.\n\n   Conclusion: rejected.\n\n5. Use leading colons::\n\n       :Author: Me\n       :Version: 1\n\n   Advantages: unambiguous, obvious (*almost* RFC822-compliant),\n   flexible, perhaps even elegant.  Disadvantages: no precedent, not\n   quite RFC822-compliant.\n\n   Conclusion: accepted!\n\n6. Use double colons::\n\n       Author:: Me\n       Version:: 1\n\n   Advantages: unambiguous, obvious? (*almost* RFC822-compliant),\n   flexible, similar to syntax already used for literal blocks and\n   directives.  Disadvantages: no precedent, not quite\n   RFC822-compliant, similar to syntax already used for literal blocks\n   and directives.\n\n   Conclusion: rejected because of the syntax similarity & conflicts.\n\nWhy is RFC822 compliance important?  It's a universal Internet\nstandard, and super obvious.  Also, I'd like to support the PEP format\n(ulterior motive: get PEPs to use reStructuredText as their standard).\nBut it *would* be easy to get used to an alternative (easy even to\nconvert PEPs; probably harder to convert python-deviants ;-).\n\nUnfortunately, without well-defined context (such as in email headers:\nRFC822 only applies before any blank lines), the RFC822 format is\nambiguous.  It is very common in ordinary text.  To implement field\nlists unambiguously, we need explicit syntax.\n\nThe following question was posed in a footnote:\n\n   Should \"bibliographic field lists\" be defined at the parser level,\n   or at the DPS transformation level?  In other words, are they\n   reStructuredText-specific, or would they also be applicable to\n   another (many/every other?) syntax?\n\nThe answer is that bibliographic fields are a\nreStructuredText-specific markup convention.  Other syntaxes may\nimplement the bibliographic elements explicitly.  For example, there\nwould be no need for such a transformation for an XML-based markup\nsyntax.\n\n.. _RFC822: https://www.rfc-editor.org/rfc/rfc822.txt\n\n\nInterpreted Text \"Roles\"\n========================\n\nThe original purpose of interpreted text was as a mechanism for\ndescriptive markup, to describe the nature or role of a word or\nphrase.  For example, in XML we could say \"<function>len</function>\"\nto mark up \"len\" as a function.  It is envisaged that within Python\ndocstrings (inline documentation in Python module source files, the\nprimary market for reStructuredText) the role of a piece of\ninterpreted text can be inferred implicitly from the context of the\ndocstring within the program source.  For other applications, however,\nthe role may have to be indicated explicitly.\n\nInterpreted text is enclosed in single backquotes (`).\n\n1. Initially, it was proposed that an explicit role could be indicated\n   as a word or phrase within the enclosing backquotes:\n\n   - As a prefix, separated by a colon and whitespace::\n\n         `role: interpreted text`\n\n   - As a suffix, separated by whitespace and a colon::\n\n         `interpreted text :role`\n\n   There are problems with the initial approach:\n\n   - There could be ambiguity with interpreted text containing colons.\n     For example, an index entry of \"Mission: Impossible\" would\n     require a backslash-escaped colon.\n\n   - The explicit role is descriptive markup, not content, and will\n     not be visible in the processed output.  Putting it inside the\n     backquotes doesn't feel right; the *role* isn't being quoted.\n\n2. Tony Ibbs suggested that the role be placed outside the\n   backquotes::\n\n       role:`prefix` or `suffix`:role\n\n   This removes the embedded-colons ambiguity, but limits the role\n   identifier to be a single word (whitespace would be illegal).\n   Since roles are not meant to be visible after processing, the lack\n   of whitespace support is not important.\n\n   The suggested syntax remains ambiguous with respect to ratios and\n   some writing styles.  For example, suppose there is a \"signal\"\n   identifier, and we write::\n\n       ...calculate the `signal`:noise ratio.\n\n   \"noise\" looks like a role.\n\n3. As an improvement on #2, we can bracket the role with colons::\n\n       :role:`prefix` or `suffix`:role:\n\n   This syntax is similar to that of field lists, which is fine since\n   both are doing similar things: describing.\n\n   This is the syntax chosen for reStructuredText.\n\n4. Another alternative is two colons instead of one::\n\n       role::`prefix` or `suffix`::role\n\n   But this is used for analogies (\"A:B::C:D\": \"A is to B as C is to\n   D\").\n\n   Both alternative #2 and #4 lack delimiters on both sides of the\n   role, making it difficult to parse (by the reader).\n\n5. Some kind of bracketing could be used:\n\n   - Parentheses::\n\n         (role)`prefix` or `suffix`(role)\n\n   - Braces::\n\n         {role}`prefix` or `suffix`{role}\n\n   - Square brackets::\n\n         [role]`prefix` or `suffix`[role]\n\n   - Angle brackets::\n\n         <role>`prefix` or `suffix`<role>\n\n     (The overlap of \\*ML tags with angle brackets would be too\n     confusing and precludes their use.)\n\nSyntax #3 was chosen for reStructuredText.\n\n\nComments\n========\n\nA problem with comments (actually, with all indented constructs) is\nthat they cannot be followed by an indented block -- a block quote --\nwithout swallowing it up.\n\nI thought that perhaps comments should be one-liners only.  But would\nthis mean that footnotes, hyperlink targets, and directives must then\nalso be one-liners?  Not a good solution.\n\nTony Ibbs suggested a \"comment\" directive.  I added that we could\nlimit a comment to a single text block, and that a \"multi-block\ncomment\" could use \"comment-start\" and \"comment-end\" directives.  This\nwould remove the indentation incompatibility.  A \"comment\" directive\nautomatically suggests \"footnote\" and (hyperlink) \"target\" directives\nas well.  This could go on forever!  Bad choice.\n\nGarth Kidd suggested that an \"empty comment\", a \"..\" explicit markup\nstart with nothing on the first line (except possibly whitespace) and\na blank line immediately following, could serve as an \"unindent\".  An\nempty comment does **not** swallow up indented blocks following it,\nso block quotes are safe.  \"A tiny but practical wart.\"  Accepted.\n\n\nAnonymous Hyperlinks\n====================\n\nAlan Jaffray came up with this idea, along with the following syntax::\n\n    Search the `Python DOC-SIG mailing list archives`{}_.\n\n    .. _: https://mail.python.org/pipermail/doc-sig/\n\nThe idea is sound and useful.  I suggested a \"double underscore\"\nsyntax::\n\n    Search the `Python DOC-SIG mailing list archives`__.\n\n    .. __: https://mail.python.org/pipermail/doc-sig/\n\nBut perhaps single underscores are okay?  The syntax looks better, but\nthe hyperlink itself doesn't explicitly say \"anonymous\"::\n\n    Search the `Python DOC-SIG mailing list archives`_.\n\n    .. _: https://mail.python.org/pipermail/doc-sig/\n\nMixing anonymous and named hyperlinks becomes confusing.  The order of\ntargets is not significant for named hyperlinks, but it is for\nanonymous hyperlinks::\n\n    Hyperlinks: anonymous_, named_, and another anonymous_.\n\n    .. _named: named\n    .. _: anonymous1\n    .. _: anonymous2\n\nWithout the extra syntax of double underscores, determining which\nhyperlink references are anonymous may be difficult.  We'd have to\ncheck which references don't have corresponding targets, and match\nthose up with anonymous targets.  Keeping to a simple consistent\nordering (as with auto-numbered footnotes) seems simplest.\n\nreStructuredText will use the explicit double-underscore syntax for\nanonymous hyperlinks.  An alternative (see `Reworking Explicit Markup\n(Round 1)`_ below) for the somewhat awkward \".. __:\" syntax is \"__\"::\n\n    An anonymous__ reference.\n\n    __ http://anonymous\n\n\nReworking Explicit Markup (Round 1)\n===================================\n\nAlan Jaffray came up with the idea of `anonymous hyperlinks`_, added\nto reStructuredText.  Subsequently it was asserted that hyperlinks\n(especially anonymous hyperlinks) would play an increasingly important\nrole in reStructuredText documents, and therefore they require a\nsimpler and more concise syntax.  This prompted a review of the\ncurrent and proposed explicit markup syntaxes with regards to\nimproving usability.\n\n1. Original syntax::\n\n       .. _blah:                     internal hyperlink target\n       .. _blah: http://somewhere    external hyperlink target\n       .. _blah: blahblah_           indirect hyperlink target\n       .. __:                        anonymous internal target\n       .. __: http://somewhere       anonymous external target\n       .. __: blahblah_              anonymous indirect target\n       .. [blah] http://somewhere    footnote\n       .. blah:: http://somewhere    directive\n       .. blah: http://somewhere     comment\n\n   .. Note::\n\n      The comment text was intentionally made to look like a hyperlink\n      target.\n\n   Origins:\n\n   * Except for the colon (a delimiter necessary to allow for\n     phrase-links), hyperlink target ``.. _blah:`` comes from Setext.\n   * Comment syntax from Setext.\n   * Footnote syntax from StructuredText (\"named links\").\n   * Directives and anonymous hyperlinks original to reStructuredText.\n\n   Advantages:\n\n   + Consistent explicit markup indicator: \"..\".\n   + Consistent hyperlink syntax: \".. _\" & \":\".\n\n   Disadvantages:\n\n   - Anonymous target markup is awkward: \".. __:\".\n   - The explicit markup indicator (\"..\") is excessively overloaded?\n   - Comment text is limited (can't look like a footnote, hyperlink,\n     or directive).  But this is probably not important.\n\n2. Alan Jaffray's proposed syntax #1::\n\n       __ _blah                      internal hyperlink target\n       __ blah: http://somewhere     external hyperlink target\n       __ blah: blahblah_            indirect hyperlink target\n       __                            anonymous internal target\n       __ http://somewhere           anonymous external target\n       __ blahblah_                  anonymous indirect target\n       __ [blah] http://somewhere    footnote\n       .. blah:: http://somewhere    directive\n       .. blah: http://somewhere     comment\n\n   The hyperlink-connoted underscores have become first-level syntax.\n\n   Advantages:\n\n   + Anonymous targets are simpler.\n   + All hyperlink targets are one character shorter.\n\n   Disadvantages:\n\n   - Inconsistent internal hyperlink targets.  Unlike all other named\n     hyperlink targets, there's no colon.  There's an extra leading\n     underscore, but we can't drop it because without it, \"blah\" looks\n     like a relative URI.  Unless we restore the colon::\n\n         __ blah:                      internal hyperlink target\n\n   - Obtrusive markup?\n\n3. Alan Jaffray's proposed syntax #2::\n\n       .. _blah                      internal hyperlink target\n       .. blah: http://somewhere     external hyperlink target\n       .. blah: blahblah_            indirect hyperlink target\n       ..                            anonymous internal target\n       .. http://somewhere           anonymous external target\n       .. blahblah_                  anonymous indirect target\n       .. [blah] http://somewhere    footnote\n       !! blah: http://somewhere     directive\n       ## blah: http://somewhere     comment\n\n   Leading underscores have been (almost) replaced by \"..\", while\n   comments and directives have gained their own syntax.\n\n   Advantages:\n\n   + Anonymous hyperlinks are simpler.\n   + Unique syntax for comments.  Connotation of \"comment\" from\n     some programming languages (including our favorite).\n   + Unique syntax for directives.  Connotation of \"action!\".\n\n   Disadvantages:\n\n   - Inconsistent internal hyperlink targets.  Again, unlike all other\n     named hyperlink targets, there's no colon.  There's a leading\n     underscore, matching the trailing underscores of references,\n     which no other hyperlink targets have.  We can't drop that one\n     leading underscore though: without it, \"blah\" looks like a\n     relative URI.  Again, unless we restore the colon::\n\n         .. blah:                      internal hyperlink target\n\n   - All (except for internal) hyperlink targets lack their leading\n     underscores, losing the \"hyperlink\" connotation.\n\n   - Obtrusive syntax for comments.  Alternatives::\n\n         ;; blah: http://somewhere\n            (also comment syntax in Lisp & others)\n         ,, blah: http://somewhere\n            (\"comma comma\": sounds like \"comment\"!)\n\n   - Iffy syntax for directives.  Alternatives?\n\n4. Tony Ibbs' proposed syntax::\n\n       .. _blah:                     internal hyperlink target\n       .. _blah: http://somewhere    external hyperlink target\n       .. _blah: blahblah_           indirect hyperlink target\n       ..                            anonymous internal target\n       .. http://somewhere           anonymous external target\n       .. blahblah_                  anonymous indirect target\n       .. [blah] http://somewhere    footnote\n       .. blah:: http://somewhere    directive\n       .. blah: http://somewhere     comment\n\n   This is the same as the current syntax, except for anonymous\n   targets which drop their \"__: \".\n\n   Advantage:\n\n   + Anonymous targets are simpler.\n\n   Disadvantages:\n\n   - Anonymous targets lack their leading underscores, losing the\n     \"hyperlink\" connotation.\n   - Anonymous targets are almost indistinguishable from comments.\n     (Better to know \"up front\".)\n\n5. David Goodger's proposed syntax: Perhaps going back to one of\n   Alan's earlier suggestions might be the best solution.  How about\n   simply adding \"__ \" as a synonym for \".. __: \" in the original\n   syntax?  These would become equivalent::\n\n       .. __:                        anonymous internal target\n       .. __: http://somewhere       anonymous external target\n       .. __: blahblah_              anonymous indirect target\n\n       __                            anonymous internal target\n       __ http://somewhere           anonymous external target\n       __ blahblah_                  anonymous indirect target\n\nAlternative 5 has been adopted.\n\n\nBackquotes in Phrase-Links\n==========================\n\n[From a 2001-06-05 Doc-SIG post in reply to questions from Doug\nHellmann.]\n\nThe first draft of the spec, posted to the Doc-SIG in November 2000,\nused square brackets for phrase-links.  I changed my mind because:\n\n1. In the first draft, I had already decided on single-backquotes for\n   inline literal text.\n\n2. However, I wanted to minimize the necessity for backslash escapes,\n   for example when quoting Python repr-equivalent syntax that uses\n   backquotes.\n\n3. The processing of identifiers (function/method/attribute/module\n   etc. names) into hyperlinks is a useful feature.  PyDoc recognizes\n   identifiers heuristically, but it doesn't take much imagination to\n   come up with counter-examples where PyDoc's heuristics would result\n   in embarrassing failure.  I wanted to do it deterministically, and\n   that called for syntax.  I called this construct \"interpreted\n   text\".\n\n4. Leveraging off the ``*emphasis*/**strong**`` syntax, lead to the\n   idea of using double-backquotes as syntax.\n\n5. I worked out some rules for inline markup recognition.\n\n6. In combination with #5, double backquotes lent themselves to inline\n   literals, neatly satisfying #2, minimizing backslash escapes.  In\n   fact, the spec says that no interpretation of any kind is done\n   within double-backquote inline literal text; backslashes do *no*\n   escaping within literal text.\n\n7. Single backquotes are then freed up for interpreted text.\n\n8. I already had square brackets required for footnote references.\n\n9. Since interpreted text will typically turn into hyperlinks, it was\n   a natural fit to use backquotes as the phrase-quoting syntax for\n   trailing-underscore hyperlinks.\n\nThe original inspiration for the trailing underscore hyperlink syntax\nwas Setext.  But for phrases Setext used a very cumbersome\n``underscores_between_words_like_this_`` syntax.\n\nThe underscores can be viewed as if they were right-pointing arrows:\n``-->``.  So ``hyperlink_`` points away from the reference, and\n``.. _hyperlink:`` points toward the target.\n\n\nSubstitution Mechanism\n======================\n\nSubstitutions arose out of a Doc-SIG thread begun on 2001-10-28 by\nAlan Jaffray, \"reStructuredText inline markup\".  It reminded me of a\nmissing piece of the reStructuredText puzzle, first referred to in my\ncontribution to \"Documentation markup & processing / PEPs\" (Doc-SIG\n2001-06-21).\n\nSubstitutions allow the power and flexibility of directives to be\nshared by inline text.  They are a way to allow arbitrarily complex\ninline objects, while keeping the details out of the flow of text.\nThey are the equivalent of SGML/XML's named entities.  For example, an\ninline image (using reference syntax alternative 4d (vertical bars)\nand definition alternative 3, the alternatives chosen for inclusion in\nthe spec)::\n\n    The |biohazard| symbol must be used on containers used to dispose\n    of medical waste.\n\n    .. |biohazard| image:: biohazard.png\n       [height=20 width=20]\n\nThe ``|biohazard|`` substitution reference will be replaced in-line by\nwhatever the ``.. |biohazard|`` substitution definition generates (in\nthis case, an image).  A substitution definition contains the\nsubstitution text bracketed with vertical bars, followed by a an\nembedded inline-compatible directive, such as \"image\".  A transform is\nrequired to complete the substitution.\n\nSyntax alternatives for the reference:\n\n1. Use the existing interpreted text syntax, with a predefined role\n   such as \"sub\"::\n\n       The `biohazard`:sub: symbol...\n\n   Advantages: existing syntax, explicit.  Disadvantages: verbose,\n   obtrusive.\n\n2. Use a variant of the interpreted text syntax, with a new suffix\n   akin to the underscore in phrase-link references::\n\n       (a) `name`@\n       (b) `name`#\n       (c) `name`&\n       (d) `name`/\n       (e) `name`<\n       (f) `name`::\n       (g) `name`:\n\n\n   Due to incompatibility with other constructs and ordinary text\n   usage, (f) and (g) are not possible.\n\n3. Use interpreted text syntax with a fixed internal format::\n\n       (a) `:name:`\n       (b) `name:`\n       (c) `name::`\n       (d) `::name::`\n       (e) `%name%`\n       (f) `#name#`\n       (g) `/name/`\n       (h) `&name&`\n       (i) `|name|`\n       (j) `[name]`\n       (k) `<name>`\n       (l) `&name;`\n       (m) `'name'`\n\n   To avoid ML confusion (k) and (l) are definitely out.  Square\n   brackets (j) won't work in the target (the substitution definition\n   would be indistinguishable from a footnote).\n\n   The ```/name/``` syntax (g) is reminiscent of \"s/find/sub\"\n   substitution syntax in ed-like languages.  However, it may have a\n   misleading association with regexps, and looks like an absolute\n   POSIX path.  (i) is visually equivalent and lacking the\n   connotations.\n\n   A disadvantage of all of these is that they limit interpreted text,\n   albeit only slightly.\n\n4. Use specialized syntax, something new::\n\n       (a) #name#\n       (b) @name@\n       (c) /name/\n       (d) |name|\n       (e) <<name>>\n       (f) //name//\n       (g) ||name||\n       (h) ^name^\n       (i) [[name]]\n       (j) ~name~\n       (k) !name!\n       (l) =name=\n       (m) ?name?\n       (n) >name<\n\n   \"#\" (a) and \"@\" (b) are obtrusive.  \"/\" (c) without backquotes\n   looks just like a POSIX path; it is likely for such usage to appear\n   in text.\n\n   \"|\" (d) and \"^\" (h) are feasible.\n\n5. Redefine the trailing underscore syntax.  See definition syntax\n   alternative 4, below.\n\nSyntax alternatives for the definition:\n\n1. Use the existing directive syntax, with a predefined directive such\n   as \"sub\".  It contains a further embedded directive resolving to an\n   inline-compatible object::\n\n       .. sub:: biohazard\n          .. image:: biohazard.png\n             [height=20 width=20]\n\n       .. sub:: parrot\n          That bird wouldn't *voom* if you put 10,000,000 volts\n          through it!\n\n   The advantages and disadvantages are the same as in inline\n   alternative 1.\n\n2. Use syntax as in #1, but with an embedded directivecompressed::\n\n       .. sub:: biohazard image:: biohazard.png\n          [height=20 width=20]\n\n   This is a bit better than alternative 1, but still too much.\n\n3. Use a variant of directive syntax, incorporating the substitution\n   text, obviating the need for a special \"sub\" directive name.  If we\n   assume reference alternative 4d (vertical bars), the matching\n   definition would look like this::\n\n       .. |biohazard| image:: biohazard.png\n          [height=20 width=20]\n\n4. (Suggested by Alan Jaffray on Doc-SIG from 2001-11-06.)\n\n   Instead of adding new syntax, redefine the trailing underscore\n   syntax to mean \"substitution reference\" instead of \"hyperlink\n   reference\".  Alan's example::\n\n       I had lunch with Jonathan_ today.  We talked about Zope_.\n\n       .. _Jonathan: lj [user=jhl]\n       .. _Zope: https://www.zope.dev/\n\n   A problem with the proposed syntax is that URIs which look like\n   simple reference names (alphanum plus \".\", \"-\", \"_\") would be\n   indistinguishable from substitution directive names.  A more\n   consistent syntax would be::\n\n       I had lunch with Jonathan_ today.  We talked about Zope_.\n\n       .. _Jonathan: lj:: user=jhl\n       .. _Zope: https://www.zope.dev/\n\n   (``::`` after ``.. _Jonathan: lj``.)\n\n   The \"Zope\" target is a simple external hyperlink, but the\n   \"Jonathan\" target contains a directive.  Alan proposed is that the\n   reference text be replaced by whatever the referenced directive\n   (the \"directive target\") produces.  A directive reference becomes a\n   hyperlink reference if the contents of the directive target resolve\n   to a hyperlink.  If the directive target resolves to an icon, the\n   reference is replaced by an inline icon.  If the directive target\n   resolves to a hyperlink, the directive reference becomes a\n   hyperlink reference.\n\n   This seems too indirect and complicated for easy comprehension.\n\n   The reference in the text will sometimes become a link, sometimes\n   not.  Sometimes the reference text will remain, sometimes not.  We\n   don't know *at the reference*::\n\n       This is a `hyperlink reference`_; its text will remain.\n       This is an `inline icon`_; its text will disappear.\n\n   That's a problem.\n\nThe syntax that has been incorporated into the spec and parser is\nreference alternative 4d with definition alternative 3::\n\n    The |biohazard| symbol...\n\n    .. |biohazard| image:: biohazard.png\n       [height=20 width=20]\n\nWe can also combine substitution references with hyperlink references,\nby appending a \"_\" (named hyperlink reference) or \"__\" (anonymous\nhyperlink reference) suffix to the substitution reference.  This\nallows us to click on an image-link::\n\n    The |biohazard|_ symbol...\n\n    .. |biohazard| image:: biohazard.png\n       [height=20 width=20]\n    .. _biohazard: https://www.cdc.gov/\n\nThere have been several suggestions for the naming of these\nconstructs, originally called \"substitution references\" and\n\"substitutions\".\n\n1. Candidate names for the reference construct:\n\n   (a) substitution reference\n   (b) tagging reference\n   (c) inline directive reference\n   (d) directive reference\n   (e) indirect inline directive reference\n   (f) inline directive placeholder\n   (g) inline directive insertion reference\n   (h) directive insertion reference\n   (i) insertion reference\n   (j) directive macro reference\n   (k) macro reference\n   (l) substitution directive reference\n\n2. Candidate names for the definition construct:\n\n   (a) substitution\n   (b) substitution directive\n   (c) tag\n   (d) tagged directive\n   (e) directive target\n   (f) inline directive\n   (g) inline directive definition\n   (h) referenced directive\n   (i) indirect directive\n   (j) indirect directive definition\n   (k) directive definition\n   (l) indirect inline directive\n   (m) named directive definition\n   (n) inline directive insertion definition\n   (o) directive insertion definition\n   (p) insertion definition\n   (q) insertion directive\n   (r) substitution definition\n   (s) directive macro definition\n   (t) macro definition\n   (u) substitution directive definition\n   (v) substitution definition\n\n\"Inline directive reference\" (1c) seems to be an appropriate term at\nfirst, but the term \"inline\" is redundant in the case of the\nreference.  Its counterpart \"inline directive definition\" (2g) is\nawkward, because the directive definition itself is not inline.\n\n\"Directive reference\" (1d) and \"directive definition\" (2k) are too\nvague.  \"Directive definition\" could be used to refer to any\ndirective, not just those used for inline substitutions.\n\nOne meaning of the term \"macro\" (1k, 2s, 2t) is too\nprogramming-language-specific.  Also, macros are typically simple text\nsubstitution mechanisms: the text is substituted first and evaluated\nlater.  reStructuredText substitution definitions are evaluated in\nplace at parse time and substituted afterwards.\n\n\"Insertion\" (1h, 1i, 2n-2q) is almost right, but it implies that\nsomething new is getting added rather than one construct being\nreplaced by another.\n\nWhich brings us back to \"substitution\".  The overall best names are\n\"substitution reference\" (1a) and \"substitution definition\" (2v).  A\nlong way to go to add one word!\n\n\nInline External Targets\n=======================\n\nCurrently reStructuredText has two hyperlink syntax variations:\n\n* Named hyperlinks::\n\n      This is a named reference_ of one word (\"reference\").  Here is\n      a `phrase reference`_.  Phrase references may even cross `line\n      boundaries`_.\n\n      .. _reference: https://www.example.org/reference/\n      .. _phrase reference: https://www.example.org/phrase_reference/\n      .. _line boundaries: https://www.example.org/line_boundaries/\n\n  + Advantages:\n\n    - The plaintext is readable.\n    - Each target may be reused multiple times (e.g., just write\n      ``\"reference_\"`` again).\n    - No synchronized ordering of references and targets is necessary.\n\n  + Disadvantages:\n\n    - The reference text must be repeated as target names; could lead\n      to mistakes.\n    - The target URLs may be located far from the references, and hard\n      to find in the plaintext.\n\n* Anonymous hyperlinks (in current reStructuredText)::\n\n      This is an anonymous reference__.  Here is an anonymous\n      `phrase reference`__.  Phrase references may even cross `line\n      boundaries`__.\n\n      __ https://www.example.org/reference/\n      __ https://www.example.org/phrase_reference/\n      __ https://www.example.org/line_boundaries/\n\n  + Advantages:\n\n    - The plaintext is readable.\n    - The reference text does not have to be repeated.\n\n  + Disadvantages:\n\n    - References and targets must be kept in sync.\n    - Targets cannot be reused.\n    - The target URLs may be located far from the references.\n\nFor comparison and historical background, StructuredText also has two\nsyntaxes for hyperlinks:\n\n* First, ``\"reference text\":URL``::\n\n      This is a \"reference\":https://www.example.org/reference/\n      of one word (\"reference\").  Here is a \"phrase\n      reference\":https://www.example.org/phrase_reference/.\n\n* Second, ``\"reference text\", https://example.org/absolute_URL``::\n\n      This is a \"reference\", https://www.example.org/reference/\n      of one word (\"reference\").  Here is a \"phrase reference\",\n      https://www.example.org/phrase_reference/.\n\nBoth syntaxes share advantages and disadvantages:\n\n+ Advantages:\n\n  - The target is specified immediately adjacent to the reference.\n\n+ Disadvantages:\n\n  - Poor plaintext readability.\n  - Targets cannot be reused.\n  - Both syntaxes use double quotes, common in ordinary text.\n  - In the first syntax, the URL and the last word are stuck\n    together, exacerbating the line wrap problem.\n  - The second syntax is too magical; text could easily be written\n    that way by accident (although only absolute URLs are recognized\n    here, perhaps because of the potential for ambiguity).\n\nA new type of \"inline external hyperlink\" has been proposed.\n\n1. On 2002-06-28, Simon Budig proposed__ a new syntax for\n   reStructuredText hyperlinks::\n\n       This is a reference_(https://www.example.org/reference/) of one\n       word (\"reference\").  Here is a `phrase\n       reference`_(https://www.example.org/phrase_reference/).  Are\n       these examples, (single-underscore), named?  If so, `anonymous\n       references`__(https://www.example.org/anonymous/) using two\n       underscores would probably be preferable.\n\n   __ https://mail.python.org/pipermail/doc-sig/2002-June/002648.html\n\n   The syntax, advantages, and disadvantages are similar to those of\n   StructuredText.\n\n   + Advantages:\n\n     - The target is specified immediately adjacent to the reference.\n\n   + Disadvantages:\n\n     - Poor plaintext readability.\n     - Targets cannot be reused (unless named, but the semantics are\n       unclear).\n\n   + Problems:\n\n     - The ``\"`ref`_(URL)\"`` syntax forces the last word of the\n       reference text to be joined to the URL, making a potentially\n       very long word that can't be wrapped (URLs can be very long).\n       The reference and the URL should be separate.  This is a\n       symptom of the following point:\n\n     - The syntax produces a single compound construct made up of two\n       equally important parts, *with syntax in the middle*, *between*\n       the reference and the target.  This is unprecedented in\n       reStructuredText.\n\n     - The \"inline hyperlink\" text is *not* a named reference (there's\n       no lookup by name), so it shouldn't look like one.\n\n     - According to the IETF standards RFC 2396 and RFC 2732,\n       parentheses are legal URI characters and curly braces are legal\n       email characters, making their use prohibitively difficult.\n\n     - The named/anonymous semantics are unclear.\n\n2. After an analysis__ of the syntax of (1) above, we came up with the\n   following compromise syntax::\n\n       This is an anonymous reference__\n       __<https://www.example.org/reference/> of one word\n       (\"reference\").  Here is a `phrase reference`__\n       __<https://www.example.org/phrase_reference/>.  `Named\n       references`_ _<https://www.example.org/anonymous/> use single\n       underscores.\n\n   __ https://mail.python.org/pipermail/doc-sig/2002-July/002670.html\n\n   The syntax builds on that of the existing \"inline internal\n   targets\": ``an _`inline internal target`.``\n\n   + Advantages:\n\n     - The target is specified immediately adjacent to the reference,\n       improving maintainability:\n\n       - References and targets are easily kept in sync.\n       - The reference text does not have to be repeated.\n\n     - The construct is executed in two parts: references identical to\n       existing references, and targets that are new but not too big a\n       stretch from current syntax.\n\n     - There's overwhelming precedent for quoting URLs with angle\n       brackets [#]_.\n\n   + Disadvantages:\n\n     - Poor plaintext readability.\n     - Lots of \"line noise\".\n     - Targets cannot be reused (unless named; see below).\n\n   To alleviate the readability issue slightly, we could allow the\n   target to appear later, such as after the end of the sentence::\n\n       This is a named reference__ of one word (\"reference\").\n       __<https://www.example.org/reference/>  Here is a `phrase\n       reference`__.  __<https://www.example.org/phrase_reference/>\n\n   Problem: this could only work for one reference at a time\n   (reference/target pairs must be proximate [refA trgA refB trgB],\n   not interleaved [refA refB trgA trgB] or nested [refA refB trgB\n   trgA]).  This variation is too problematic; references and inline\n   external targets will have to be kept immediately adjacent (see (3)\n   below).\n\n   The ``\"reference__ __<target>\"`` syntax is actually for \"anonymous\n   inline external targets\", emphasized by the double underscores.  It\n   follows that single trailing and leading underscores would lead to\n   *implicitly named* inline external targets.  This would allow the\n   reuse of targets by name.  So after ``\"reference_ _<target>\"``,\n   another ``\"reference_\"`` would point to the same target.\n\n   .. [#]\n      From RFC 2396 (URI syntax):\n\n          The angle-bracket \"<\" and \">\" and double-quote (\")\n          characters are excluded [from URIs] because they are often\n          used as the delimiters around URI in text documents and\n          protocol fields.\n\n          Using <> angle brackets around each URI is especially\n          recommended as a delimiting style for URI that contain\n          whitespace.\n\n      From RFC 822 (email headers):\n\n          Angle brackets (\"<\" and \">\") are generally used to indicate\n          the presence of a one machine-usable reference (e.g.,\n          delimiting mailboxes), possibly including source-routing to\n          the machine.\n\n3. If it is best for references and inline external targets to be\n   immediately adjacent, then they might as well be integrated.\n   Here's an alternative syntax embedding the target URL in the\n   reference::\n\n       This is an anonymous `reference <https://www.example.org\n       /reference/>`__ of one word (\"reference\").  Here is a `phrase\n       reference <https://www.example.org/phrase_reference/>`__.\n\n   Advantages and disadvantages are similar to those in (2).\n   Readability is still an issue, but the syntax is a bit less\n   heavyweight (reduced line noise).  Backquotes are required, even\n   for one-word references; the target URL is included within the\n   reference text, forcing a phrase context.\n\n   We'll call this variant \"embedded URIs\".\n\n   Problem: how to refer to a title like \"HTML Anchors: <a>\" (which\n   ends with an HTML/SGML/XML tag)?  We could either require more\n   syntax on the target (like ``\"`reference text\n   __<https://example.org/>`__\"``), or require the odd conflicting\n   title to be escaped (like ``\"`HTML Anchors: \\<a>`__\"``).  The\n   latter seems preferable, and not too onerous.\n\n   Similarly to (2) above, a single trailing underscore would convert\n   the reference & inline external target from anonymous to implicitly\n   named, allowing reuse of targets by name.\n\n   I think this is the least objectionable of the syntax alternatives.\n\nOther syntax variations have been proposed (by Brett Cannon and Benja\nFallenstein)::\n\n    `phrase reference`->https://www.example.org\n\n    `phrase reference`@https://www.example.org\n\n    `phrase reference`__ ->https://www.example.org\n\n    `phrase reference` [-> https://www.example.org]\n\n    `phrase reference`__ [-> https://www.example.org]\n\n    `phrase reference` <https://www.example.org>_\n\nNone of these variations are clearly superior to #3 above.  Some have\nproblems that exclude their use.\n\nWith any kind of inline external target syntax it comes down to the\nconflict between maintainability and plaintext readability.  I don't\nsee a major problem with reStructuredText's maintainability, and I\ndon't want to sacrifice plaintext readability to \"improve\" it.\n\nThe proponents of inline external targets want them for easily\nmaintainable web pages.  The arguments go something like this:\n\n- Named hyperlinks are difficult to maintain because the reference\n  text is duplicated as the target name.\n\n  To which I said, \"So use anonymous hyperlinks.\"\n\n- Anonymous hyperlinks are difficult to maintain because the\n  references and targets have to be kept in sync.\n\n  \"So keep the targets close to the references, grouped after each\n  paragraph.  Maintenance is trivial.\"\n\n- But targets grouped after paragraphs break the flow of text.\n\n  \"Surely less than URLs embedded in the text!  And if the intent is\n  to produce web pages, not readable plaintext, then who cares about\n  the flow of text?\"\n\nMany participants have voiced their objections to the proposed syntax:\n\n    Garth Kidd: \"I strongly prefer the current way of doing it.\n    Inline is spectactularly messy, IMHO.\"\n\n    Tony Ibbs: \"I vehemently agree... that the inline alternatives\n    being suggested look messy - there are/were good reasons they've\n    been taken out...  I don't believe I would gain from the new\n    syntaxes.\"\n\n    Paul Moore: \"I agree as well.  The proposed syntax is far too\n    punctuation-heavy, and any of the alternatives discussed are\n    ambiguous or too subtle.\"\n\nOthers have voiced their support:\n\n    fantasai: \"I agree with Simon.  In many cases, though certainly\n    not in all, I find parenthesizing the url in plain text flows\n    better than relegating it to a footnote.\"\n\n    Ken Manheimer: \"I'd like to weigh in requesting some kind of easy,\n    direct inline reference link.\"\n\n(Interesting that those *against* the proposal have been using\nreStructuredText for a while, and those *for* the proposal are either\nnew to the list [\"fantasai\", background unknown] or longtime\nStructuredText users [Ken Manheimer].)\n\nI was initially ambivalent/against the proposed \"inline external\ntargets\".  I value reStructuredText's readability very highly, and\nalthough the proposed syntax offers convenience, I don't know if the\nconvenience is worth the cost in ugliness.  Does the proposed syntax\ncompromise readability too much, or should the choice be left up to\nthe author?  Perhaps if the syntax is *allowed* but its use strongly\n*discouraged*, for aesthetic/readability reasons?\n\nAfter a great deal of thought and much input from users, I've decided\nthat there are reasonable use cases for this construct.  The\ndocumentation should strongly caution against its use in most\nsituations, recommending independent block-level targets instead.\nSyntax #3 above (\"embedded URIs\") will be used.\n\n\nDoctree Representation of Transitions\n=====================================\n\n(Although not reStructuredText-specific, this section fits best in\nthis document.)\n\nHaving added the \"horizontal rule\" construct to the `reStructuredText\nMarkup Specification`_, a decision had to be made as to how to reflect\nthe construct in the implementation of the document tree.  Given this\nsource::\n\n    Document\n    ========\n\n    Paragraph 1\n\n    --------\n\n    Paragraph 2\n\nThe horizontal rule indicates a \"transition\" (in prose terms) or the\nstart of a new \"division\".  Before implementation, the parsed document\ntree would be::\n\n    <document>\n        <section names=\"document\">\n            <title>\n                Document\n            <paragraph>\n                Paragraph 1\n            --------               <--- error here\n            <paragraph>\n                Paragraph 2\n\nThere are several possibilities for the implementation:\n\n1. Implement horizontal rules as \"divisions\" or segments.  A\n   \"division\" is a title-less, non-hierarchical section.  The first\n   try at an implementation looked like this::\n\n       <document>\n           <section names=\"document\">\n               <title>\n                   Document\n               <paragraph>\n                   Paragraph 1\n               <division>\n                   <paragraph>\n                       Paragraph 2\n\n   But the two paragraphs are really at the same level; they shouldn't\n   appear to be at different levels.  There's really an invisible\n   \"first division\".  The horizontal rule splits the document body\n   into two segments, which should be treated uniformly.\n\n2. Treating \"divisions\" uniformly brings us to the second\n   possibility::\n\n       <document>\n           <section names=\"document\">\n               <title>\n                   Document\n               <division>\n                   <paragraph>\n                       Paragraph 1\n               <division>\n                   <paragraph>\n                       Paragraph 2\n\n   With this change, documents and sections will directly contain\n   divisions and sections, but not body elements.  Only divisions will\n   directly contain body elements.  Even without a horizontal rule\n   anywhere, the body elements of a document or section would be\n   contained within a division element.  This makes the document tree\n   deeper.  This is similar to the way HTML_ treats document contents:\n   grouped within a ``<body>`` element.\n\n3. Implement them as \"transitions\", empty elements::\n\n       <document>\n           <section names=\"document\">\n               <title>\n                   Document\n               <paragraph>\n                   Paragraph 1\n               <transition>\n               <paragraph>\n                   Paragraph 2\n\n   A transition would be a \"point element\", not containing anything,\n   only identifying a point within the document structure.  This keeps\n   the document tree flatter, but the idea of a \"point element\" like\n   \"transition\" smells bad.  A transition isn't a thing itself, it's\n   the space between two divisions.  However, transitions are a\n   practical solution.\n\nSolution 3 was chosen for incorporation into the document tree model.\n\n.. _HTML: https://www.w3.org/MarkUp/\n\n\nSyntax for Line Blocks\n======================\n\n* An early idea: How about a literal-block-like prefix, perhaps\n  \"``;;``\"?  (It is, after all, a *semi-literal* literal block, no?)\n  Example::\n\n      Take it away, Eric the Orchestra Leader!  ;;\n\n          A one, two, a one two three four\n\n          Half a bee, philosophically,\n          must, *ipso facto*, half not be.\n          But half the bee has got to be,\n          *vis a vis* its entity.  D'you see?\n\n          But can a bee be said to be\n          or not to be an entire bee,\n          when half the bee is not a bee,\n          due to some ancient injury?\n\n          Singing...\n\n  Kinda lame.\n\n* Another idea: in an ordinary paragraph, if the first line ends with\n  a backslash (escaping the newline), interpret the entire paragraph\n  as a verse block?  For example::\n\n      Add just one backslash\\\n      And this paragraph becomes\n      An awful haiku\n\n  (Awful, and arguably invalid, since in Japanese the word \"haiku\"\n  contains three syllables not two.)\n\n  This idea was superseded by the rules for escaped whitespace, useful\n  for `character-level inline markup`_.\n\n* In a `2004-02-22 docutils-develop message`__, Jarno Elonen proposed\n  a \"plain list\" syntax (and also provided a patch)::\n\n       | John Doe\n       | President, SuperDuper Corp.\n       | jdoe@example.org\n\n  __ https://thread.gmane.org/gmane.text.docutils.devel/1187\n\n  This syntax is very natural.  However, these \"plain lists\" seem very\n  similar to line blocks, and I see so little intrinsic \"list-ness\"\n  that I'm loathe to add a new object.  I used the term \"blurbs\" to\n  remove the \"list\" connotation from the originally proposed name.\n  Perhaps line blocks could be refined to add the two properties they\n  currently lack:\n\n  A) long lines wrap nicely\n  B) HTML output doesn't look like program code in non-CSS web\n     browsers\n\n  (A) is an issue of all 3 aspects of Docutils: syntax (construct\n  behaviour), internal representation, and output.  (B) is partly an\n  issue of internal representation but mostly of output.\n\nReStructuredText will redefine line blocks with the \"|\"-quoting\nsyntax.  The following is my current thinking.\n\n\nSyntax\n------\n\nPerhaps line block syntax like this would do::\n\n     | M6: James Bond\n     | MIB: Mr. J.\n     | IMF: not decided yet, but probably one of the following:\n     |   Ethan Hunt\n     |   Jim Phelps\n     |   Claire Phelps\n     | CIA: Lea Leiter\n\nNote that the \"nested\" list does not have nested syntax (the \"|\" are\nnot further indented); the leading whitespace would still be\nsignificant somehow (more below).  As for long lines in the input,\nthis could suffice::\n\n     | John Doe\n     | Founder, President, Chief Executive Officer, Cook, Bottle\n       Washer, and All-Round Great Guy\n     | SuperDuper Corp.\n     | jdoe@example.org\n\nThe lack of \"|\" on the third line indicates that it's a continuation\nof the second line, wrapped.\n\nI don't see much point in allowing arbitrary nested content.  Multiple\nparagraphs or bullet lists inside a \"blurb\" doesn't make sense to me.\nSimple nested line blocks should suffice.\n\n\nInternal Representation\n-----------------------\n\nLine blocks are currently represented as text blobs as follows::\n\n     <!ELEMENT line_block %text.model;>\n     <!ATTLIST line_block\n         %basic.atts;\n         %fixedspace.att;>\n\nInstead, we could represent each line by a separate element::\n\n     <!ELEMENT line_block (line+)>\n     <!ATTLIST line_block %basic.atts;>\n\n     <!ELEMENT line %text.model;>\n     <!ATTLIST line %basic.atts;>\n\nWe'd keep the significance of the leading whitespace of each line\neither by converting it to non-breaking spaces at output, or with a\nper-line margin.  Non-breaking spaces are simpler (for HTML, anyway)\nbut kludgey, and wouldn't support indented long lines that wrap.  But\nshould inter-word whitespace (i.e., not leading whitespace) be\npreserved?  Currently it is preserved in line blocks.\n\nRepresenting a more complex line block may be tricky::\n\n     | But can a bee be said to be\n     |     or not to be an entire bee,\n     |         when half the bee is not a bee,\n     |             due to some ancient injury?\n\nPerhaps the representation could allow for nested line blocks::\n\n     <!ELEMENT line_block (line | line_block)+>\n\nWith this model, leading whitespace would no longer be significant.\nInstead, left margins are implied by the nesting.  The example above\ncould be represented as follows::\n\n     <line_block>\n         <line>\n             But can a bee be said to be\n         <line_block>\n             <line>\n                  or not to be an entire bee,\n             <line_block>\n                 <line>\n                     when half the bee is not a bee,\n                 <line_block>\n                     <line>\n                         due to some ancient injury?\n\nI wasn't sure what to do about even more complex line blocks::\n\n     |     Indented\n     | Not indented\n     |   Indented a bit\n     |     A bit more\n     |  Only one space\n\nHow should that be parsed and nested?  Should the first line have\nthe same nesting level (== indentation in the output) as the fourth\nline, or the same as the last line?  Mark Nodine suggested that such\nline blocks be parsed similarly to complexly-nested block quotes,\nwhich seems reasonable.  In the example above, this would result in\nthe nesting of first line matching the last line's nesting.  In\nother words, the nesting would be relative to neighboring lines\nonly.\n\n\nOutput\n------\n\nIn HTML, line blocks are currently output as \"<pre>\" blocks, which\ngives us significant whitespace and line breaks, but doesn't allow\nlong lines to wrap and causes monospaced output without stylesheets.\nInstead, we could output \"<div>\" elements parallelling the\nrepresentation above, where each nested <div class=\"line_block\"> would\nhave an increased left margin (specified in the stylesheet).\n\nJarno suggested the following HTML output::\n\n    <div class=\"line_block\">\n       <span class=\"line\">First, top level line</span><br class=\"hidden\"/>\n       <div class=\"line_block\"><span class=\"hidden\">&nbsp;</span>\n          <span class=\"line\">Second, once nested</span><br class=\"hidden\"/>\n          <span class=\"line\">Third, once nested</span><br class=\"hidden\"/>\n          ...\n       </div>\n       ...\n    </div>\n\nThe ``<br class=\"hidden\" />`` and ``<span\nclass=\"hidden\">&nbsp;</span>`` are meant to support non-CSS and\nnon-graphical browsers.  I understand the case for \"br\", but I'm not\nso sure about hidden \"&nbsp;\".  I question how much effort should be\nput toward supporting non-graphical and especially non-CSS browsers,\nat least for html4css1.py output.\n\nShould the lines themselves be ``<span>`` or ``<div>``?  I don't like\nmixing inline and block-level elements.\n\n\nImplementation Plan\n-------------------\n\nWe'll leave the old implementation in place (via the \"line-block\"\ndirective only) until all Writers have been updated to support the new\nsyntax & implementation.  The \"line-block\" directive can then be\nupdated to use the new internal representation, and its documentation\nwill be updated to recommend the new syntax.\n\n\nList-Driven Tables\n==================\n\nThe original idea came from Dylan Jay:\n\n    ... to use a two level bulleted list with something to\n    indicate it should be rendered as a table ...\n\nIt's an interesting idea.  It could be implemented in as a directive\nwhich transforms a uniform two-level list into a table.  Using a\ndirective would allow the author to explicitly set the table's\norientation (by column or by row), the presence of row headers, etc.\n\nAlternatives:\n\n1. (Implemented in Docutils 0.3.8).\n\n   Bullet-list-tables might look like this::\n\n       .. list-table::\n\n          * - Treat\n            - Quantity\n            - Description\n          * - Albatross!\n            - 299\n            - On a stick!\n          * - Crunchy Frog!\n            - 1499\n            - If we took the bones out, it wouldn't be crunchy,\n              now would it?\n          * - Gannet Ripple!\n            - 199\n            - On a stick!\n\n   This list must be written in two levels.  This wouldn't work::\n\n       .. list-table::\n\n          * Treat\n          * Albatross!\n          * Gannet!\n          * Crunchy Frog!\n\n          * Quantity\n          * 299\n          * 199\n          * 1499\n\n          * Description\n          * On a stick!\n          * On a stick!\n          * If we took the bones out...\n\n   The above is a single list of 12 items.  The blank lines are not\n   significant to the markup.  We'd have to explicitly specify how\n   many columns or rows to use, which isn't a good idea.\n\n2. Beni Cherniavsky suggested a field list alternative.  It could look\n   like this::\n\n       .. field-list-table::\n          :headrows: 1\n\n          - :treat: Treat\n            :quantity: Quantity\n            :descr: Description\n\n          - :treat: Albatross!\n            :quantity: 299\n            :descr: On a stick!\n\n          - :treat: Crunchy Frog!\n            :quantity: 1499\n            :descr: If we took the bones out, it wouldn't be\n                    crunchy, now would it?\n\n   Column order is determined from the order of fields in the first\n   row.  Field order in all other rows is ignored.  As a side-effect,\n   this allows trivial re-arrangement of columns.  By using named\n   fields, it becomes possible to omit fields in some rows without\n   losing track of things, which is important for spans.\n\n3. An alternative to two-level bullet lists would be to use enumerated\n   lists for the table cells::\n\n       .. list-table::\n\n           * 1. Treat\n             2. Quantity\n             3. Description\n           * 1. Albatross!\n             2. 299\n             3. On a stick!\n           * 1. Crunchy Frog!\n             2. 1499\n             3. If we took the bones out, it wouldn't be crunchy,\n                now would it?\n\n   That provides better correspondence between cells in the same\n   column than does bullet-list syntax, but not as good as field list\n   syntax.  I think that were only field-list-tables available, a lot\n   of users would use the equivalent degenerate case::\n\n       .. field-list-table::\n           - :1: Treat\n             :2: Quantity\n             :3: Description\n           ...\n\n4. Another natural variant is to allow a description list with field\n   lists as descriptions::\n\n       .. list-table::\n           :headrows: 1\n\n           Treat\n               :quantity: Quantity\n               :descr: Description\n           Albatross!\n               :quantity: 299\n               :descr: On a stick!\n           Crunchy Frog!\n               :quantity: 1499\n               :descr: If we took the bones out, it wouldn't be\n                       crunchy, now would it?\n\n   This would make the whole first column a header column (\"stub\").\n   It's limited to a single column and a single paragraph fitting on\n   one source line.  Also it wouldn't allow for empty cells or row\n   spans in the first column.  But these are limitations that we could\n   live with, like those of simple tables.\n\nThe List-driven table feature could be done in many ways.  Each user\nwill have their preferred usage.  Perhaps a single \"list-table\"\ndirective could handle them all, depending on which options and\ncontent are present.\n\nIssues:\n\n* How to indicate that there's 1 header row?  Perhaps two lists?  ::\n\n      .. list-table::\n\n         + - Treat\n           - Quantity\n           - Description\n\n         * - Albatross!\n           - 299\n           - On a stick!\n\n  This is probably too subtle though.  Better would be a directive\n  option, like ``:headrows: 1``.  An early suggestion for the header\n  row(s) was to use a directive option::\n\n      .. field-list-table::\n         :header:\n             - :treat: Treat\n               :quantity: Quantity\n               :descr: Description\n         - :treat: Albatross!\n           :quantity: 299\n           :descr: On a stick!\n\n  But the table data is at two levels and looks inconsistent.\n\n  In general, we cannot extract the header row from field lists' field\n  names because field names cannot contain everything one might put in\n  a table cell.  A separate header row also allows shorter field names\n  and doesn't force one to rewrite the whole table when the header\n  text changes.  But for simpler cases, we can offer a \":header:\n  fields\" option, which does extract header cells from field names::\n\n      .. field-list-table::\n          :header: fields\n\n          - :Treat: Albatross!\n            :Quantity: 299\n            :Description: On a stick!\n\n* How to indicate the column widths?  A directive option? ::\n\n      .. list-table::\n         :widths: 15 10 35\n\n  Automatic defaults from the text used?\n\n* How to handle row and/or column spans?\n\n  In a field list, column-spans can be indicated by specifying the\n  first and last fields, separated by space-dash-space or ellipsis::\n\n      - :foo - baz: quuux\n      - :foo ... baz: quuux\n\n  Commas were proposed for column spans::\n\n      - :foo, bar: quux\n\n  But non-adjacent columns become problematic.  Should we report an\n  error, or duplicate the value into each span of adjacent columns (as\n  was suggested)?  The latter suggestion is appealing but may be too\n  clever.  Best perhaps to simply specify the two ends.\n\n  It was suggested that comma syntax should be allowed, too, in order\n  to allow the user to avoid trouble when changing the column order.\n  But changing the column order of a table with spans is not trivial;\n  we shouldn't make it easier to mess up.\n\n  One possible syntax for row-spans is to simply treat any row where a\n  field is missing as a row-span from the last row where it appeared.\n  Leaving a field empty would still be possible by writing a field\n  with empty content.  But this is too implicit.\n\n  Another way would be to require an explicit continuation marker\n  (``...``/``-\"-``/``\"``?) in all but the first row of a spanned\n  field.  Empty comments could work (\"..\").  If implemented, the same\n  marker could also be supported in simple tables, which lack\n  row-spanning abilities.\n\n  Explicit markup like \":rowspan:\" and \":colspan:\" was also suggested.\n\n  Sometimes in a table, the first header row contains spans.  It may\n  be necessary to provide a way to specify the column field names\n  independently of data rows.  A directive option would do it.\n\n* We could specify \"column-wise\" or \"row-wise\" ordering, with the same\n  markup structure.  For example, with definition data::\n\n      .. list-table::\n         :column-wise:\n\n         Treat\n             - Albatross!\n             - Crunchy Frog!\n         Quantity\n             - 299\n             - 1499\n         Description\n             - On a stick!\n             - If we took the bones out, it wouldn't be\n               crunchy, now would it?\n\n* A syntax for _`stubs in grid tables` is easy to imagine::\n\n      +------------------------++------------+----------+\n      | Header row, column 1   || Header 2   | Header 3 |\n      +========================++============+==========+\n      | body row 1, column 1   || column 2   | column 3 |\n      +------------------------++------------+----------+\n\n  Or this idea from Nick Moffitt::\n\n      +-----+---+---+\n      | XOR # T | F |\n      +=====+===+===+\n      |   T # F | T |\n      +-----+---+---+\n      |   F # T | F |\n      +-----+---+---+\n\n\nAuto-Enumerated Lists\n=====================\n\nImplemented 2005-03-24: combination of variation 1 & 2.\n\nThe advantage of auto-numbered enumerated lists would be similar to\nthat of auto-numbered footnotes: lists could be written and rearranged\nwithout having to manually renumber them.  The disadvantages are also\nthe same: input and output wouldn't match exactly; the markup may be\nugly or confusing (depending on which alternative is chosen).\n\n1. Use the \"#\" symbol.  Example::\n\n       #. Item 1.\n       #. Item 2.\n       #. Item 3.\n\n   Advantages: simple, explicit.  Disadvantage: enumeration sequence\n   cannot be specified (limited to arabic numerals); ugly.\n\n2. As a variation on #1, first initialize the enumeration sequence?\n   For example::\n\n       a) Item a.\n       #) Item b.\n       #) Item c.\n\n   Advantages: simple, explicit, any enumeration sequence possible.\n   Disadvantages: ugly; perhaps confusing with mixed concrete/abstract\n   enumerators.\n\n3. Alternative suggested by Fred Bremmer, from experience with MoinMoin::\n\n       1. Item 1.\n       1. Item 2.\n       1. Item 3.\n\n   Advantages: enumeration sequence is explicit (could be multiple\n   \"a.\" or \"(I)\" tokens).  Disadvantages: perhaps confusing; otherwise\n   erroneous input (e.g., a duplicate item \"1.\") would pass silently,\n   either causing a problem later in the list (if no blank lines\n   between items) or creating two lists (with blanks).\n\n   Take this input for example::\n\n       1. Item 1.\n\n       1. Unintentional duplicate of item 1.\n\n       2. Item 2.\n\n   Currently the parser will produce two list, \"1\" and \"1,2\" (no\n   warnings, because of the presence of blank lines).  Using Fred's\n   notation, the current behavior is \"1,1,2 -> 1 1,2\" (without blank\n   lines between items, it would be \"1,1,2 -> 1 [WARNING] 1,2\").  What\n   should the behavior be with auto-numbering?\n\n   Fred has produced a patch__, whose initial behavior is as follows::\n\n       1,1,1   -> 1,2,3\n       1,2,2   -> 1,2,3\n       3,3,3   -> 3,4,5\n       1,2,2,3 -> 1,2,3 [WARNING] 3\n       1,1,2   -> 1,2 [WARNING] 2\n\n   (After the \"[WARNING]\", the \"3\" would begin a new list.)\n\n   I have mixed feelings about adding this functionality to the spec &\n   parser.  It would certainly be useful to some users (myself\n   included; I often have to renumber lists).  Perhaps it's too\n   clever, asking the parser to guess too much.  What if you *do* want\n   three one-item lists in a row, each beginning with \"1.\"?  You'd\n   have to use empty comments to force breaks.  Also, I question\n   whether \"1,2,2 -> 1,2,3\" is optimal behavior.\n\n   In response, Fred came up with \"a stricter and more explicit rule\n   [which] would be to only auto-number silently if *all* the\n   enumerators of a list were identical\".  In that case::\n\n       1,1,1   -> 1,2,3\n       1,2,2   -> 1,2 [WARNING] 2\n       3,3,3   -> 3,4,5\n       1,2,2,3 -> 1,2 [WARNING] 2,3\n       1,1,2   -> 1,2 [WARNING] 2\n\n   Should any start-value be allowed (\"3,3,3\"), or should\n   auto-numbered lists be limited to begin with ordinal-1 (\"1\", \"A\",\n   \"a\", \"I\", or \"i\")?\n\n   __ https://sourceforge.net/tracker/index.php?func=detail&aid=548802\n      &group_id=38414&atid=422032\n\n4. Alternative proposed by Tony Ibbs::\n\n       #1. First item.\n       #3. Aha - I edited this in later.\n       #2. Second item.\n\n   The initial proposal required unique enumerators within a list, but\n   this limits the convenience of a feature of already limited\n   applicability and convenience.  Not a useful requirement; dropped.\n\n   Instead, simply prepend a \"#\" to a standard list enumerator to\n   indicate auto-enumeration.  The numbers (or letters) of the\n   enumerators themselves are not significant, except:\n\n   - as a sequence indicator (arabic, roman, alphabetic; upper/lower),\n\n   - and perhaps as a start value (first list item).\n\n   Advantages: explicit, any enumeration sequence possible.\n   Disadvantages: a bit ugly.\n\n\nAdjacent citation references\n============================\n\nA special case for inline markup was proposed and implemented:\nmultiple citation references could be joined into one::\n\n   [cite1]_[cite2]_ instead of requiring [cite1]_ [cite2]_\n\nHowever, this was rejected as an unwarranted exception to the rules\nfor inline markup.\n(The main motivation for the proposal, grouping citations in the latex writer,\nwas implemented by recognising the second group in the example above and\ntransforming it into ``\\cite{cite1,cite2}``.)\n\n\nInline markup recognition\n=========================\n\nImplemented 2011-12-05 (version 0.9):\nExtended `inline markup recognition rules`_.\n\nNon-ASCII whitespace, punctuation characters and \"international\" quotes are\nallowed around inline markup (based on `Unicode categories`_). The rules for\nASCII characters were not changed.\n\nRejected alternatives:\n\na) Use `Unicode categories`_ for all chars (ASCII or not)\n\n   +1  comprehensible, standards based,\n   -1  many \"false positives\" need escaping,\n   -1  not backwards compatible.\n\nb) full backwards compatibility\n\n   :Pi: only before start-string\n   :Pf: only behind end-string\n   :Po: \"conservative\" sorting of other punctuation:\n\n        :``.,;!?\\\\``: Close\n        :``¡¿``:   Open\n\n   +1  backwards compatible,\n   +1  logical extension of the existing rules,\n   -1  exception list for \"other\" punctuation needed,\n   -1  rules even more complicated,\n   -1  not clear how to sort \"other\" punctuation that is currently not\n       recognized,\n   -2  international quoting convention like\n       »German ›angular‹ quotes« not recognized.\n\n.. _Inline markup recognition rules:\n   ../../ref/rst/restructuredtext.html#inline-markup-recognition-rules\n.. _Unicode categories:\n   https://www.unicode.org/Public/5.1.0/ucd/UCD.html#General_Category_Values\n\n\n-----------------\n Not Implemented\n-----------------\n\nReworking Footnotes\n===================\n\nAs a further wrinkle (see `Reworking Explicit Markup (Round 1)`_\nabove), in the wee hours of 2002-02-28 I posted several ideas for\nchanges to footnote syntax:\n\n    - Change footnote syntax from ``.. [1]`` to ``_[1]``? ...\n    - Differentiate (with new DTD elements) author-date \"citations\"\n      (``[GVR2002]``) from numbered footnotes? ...\n    - Render footnote references as superscripts without \"[]\"? ...\n\nThese ideas are all related, and suggest changes in the\nreStructuredText syntax as well as the docutils tree model.\n\nThe footnote has been used for both true footnotes (asides expanding\non points or defining terms) and for citations (references to external\nworks).  Rather than dealing with one amalgam construct, we could\nseparate the current footnote concept into strict footnotes and\ncitations.  Citations could be interpreted and treated differently\nfrom footnotes.  Footnotes would be limited to numerical labels:\nmanual (\"1\") and auto-numbered (anonymous \"#\", named \"#label\").\n\nThe footnote is the only explicit markup construct (starts with \".. \")\nthat directly translates to a visible body element.  I've always been\na little bit uncomfortable with the \".. \" marker for footnotes because\nof this; \".. \" has a connotation of \"special\", but footnotes aren't\nespecially \"special\".  Printed texts often put footnotes at the bottom\nof the page where the reference occurs (thus \"foot note\").  Some HTML\ndesigns would leave footnotes to be rendered the same positions where\nthey're defined.  Other online and printed designs will gather\nfootnotes into a section near the end of the document, converting them\nto \"endnotes\" (perhaps using a directive in our case); but this\n\"special processing\" is not an intrinsic property of the footnote\nitself, but a decision made by the document author or processing\nsystem.\n\nCitations are almost invariably collected in a section at the end of a\ndocument or section.  Citations \"disappear\" from where they are\ndefined and are magically reinserted at some well-defined point.\nThere's more of a connection to the \"special\" connotation of the \".. \"\nsyntax.  The point at which the list of citations is inserted could be\ndefined manually by a directive (e.g., \".. citations::\"), and/or have\ndefault behavior (e.g., a section automatically inserted at the end of\nthe document) that might be influenced by options to the Writer.\n\nSyntax proposals:\n\n+ Footnotes:\n\n  - Current syntax::\n\n        .. [1] Footnote 1\n        .. [#] Auto-numbered footnote.\n        .. [#label] Auto-labeled footnote.\n\n  - The syntax proposed in the original 2002-02-28 Doc-SIG post:\n    remove the \".. \", prefix a \"_\"::\n\n        _[1] Footnote 1\n        _[#] Auto-numbered footnote.\n        _[#label] Auto-labeled footnote.\n\n    The leading underscore syntax (earlier dropped because\n    ``.. _[1]:`` was too verbose) is a useful reminder that footnotes\n    are hyperlink targets.\n\n  - Minimal syntax: remove the \".. [\" and \"]\", prefix a \"_\", and\n    suffix a \".\"::\n\n        _1. Footnote 1.\n        _#. Auto-numbered footnote.\n        _#label. Auto-labeled footnote.\n\n                 ``_1.``, ``_#.``, and ``_#label.`` are markers,\n                 like list markers.\n\n    Footnotes could be rendered something like this in HTML\n\n        | 1. This is a footnote.  The brackets could be dropped\n        |    from the label, and a vertical bar could set them\n        |    off from the rest of the document in the HTML.\n\n    Two-way hyperlinks on the footnote marker (\"1.\" above) would also\n    help to differentiate footnotes from enumerated lists.\n\n    If converted to endnotes (by a directive/transform), a horizontal\n    half-line might be used instead.  Page-oriented output formats\n    would typically use the horizontal line for true footnotes.\n\n+ Footnote references:\n\n  - Current syntax::\n\n        [1]_, [#]_, [#label]_\n\n  - Minimal syntax to match the minimal footnote syntax above::\n\n        1_, #_, #label_\n\n    As a consequence, pure-numeric hyperlink references would not be\n    possible; they'd be interpreted as footnote references.\n\n+ Citation references: no change is proposed from the current footnote\n  reference syntax::\n\n      [GVR2001]_\n\n+ Citations:\n\n  - Current syntax (footnote syntax)::\n\n        ..

The current footnote syntax for\ncitations is better than the alternatives given.\n\nFrom a reply by Tony Ibbs on 2002-03-01:\n\n    However, I think easier with examples, so let's create one::\n\n        Fans of Terry Pratchett are perhaps more likely to use\n        footnotes [1]_ in their own writings than other people\n        [2]_.  Of course, in *general*, one only sees footnotes\n        in academic or technical writing - it's use in fiction\n        and letter writing is not normally considered good\n        style [4]_, particularly in emails (not a medium that\n        lends itself to footnotes).\n\n        ..

[3] Although he has the distinction of being\n           *funny* when he does it, and his fans don't always\n           achieve that aim.\n        .. [4] Presumably because it detracts from linear\n           reading of the text - this is, of course, the point.\n\n    and look at it with the second syntax proposal::\n\n        Fans of Terry Pratchett are perhaps more likely to use\n        footnotes [1]_ in their own writings than other people\n        [2]_.  Of course, in *general*, one only sees footnotes\n        in academic or technical writing - it's use in fiction\n        and letter writing is not normally considered good\n        style [4]_, particularly in emails (not a medium that\n        lends itself to footnotes).\n\n        _[1] That is, little bits of referenced text at the\n             bottom of the page.\n        _[2] Because Terry himself does, of course [3]_.\n        _[3] Although he has the distinction of being\n             *funny* when he does it, and his fans don't always\n             achieve that aim.\n        _[4] Presumably because it detracts from linear\n             reading of the text - this is, of course, the point.\n\n    (I note here that if I have gotten the indentation of the\n    footnotes themselves correct, this is clearly not as nice.  And if\n    the indentation should be to the left margin instead, I like that\n    even less).\n\n    and the third (new) proposal::\n\n        Fans of Terry Pratchett are perhaps more likely to use\n        footnotes 1_ in their own writings than other people\n        2_.  Of course, in *general*, one only sees footnotes\n        in academic or technical writing - it's use in fiction\n        and letter writing is not normally considered good\n        style 4_, particularly in emails (not a medium that\n        lends itself to footnotes).\n\n        _1. That is, little bits of referenced text at the\n            bottom of the page.\n        _2. Because Terry himself does, of course 3_.\n        _3. Although he has the distinction of being\n            *funny* when he does it, and his fans don't always\n            achieve that aim.\n        _4. Presumably because it detracts from linear\n            reading of the text - this is, of course, the point.\n\n    I think I don't, in practice, mind the targets too much (the use\n    of a dot after the number helps a lot here), but I do have a\n    problem with the body text, in that I don't naturally separate out\n    the footnotes as different than the rest of the text - instead I\n    keep wondering why there are numbers interspered in the text.  The\n    use of brackets around the numbers ([ and ]) made me somehow parse\n    the footnote references as \"odd\" - i.e., not part of the body text\n    - and thus both easier to skip, and also (paradoxically) easier to\n    pick out so that I could follow them.\n\n    Thus, for the moment (and as always susceptable to argument), I'd\n    say -1 on the new form of footnote reference (i.e., I much prefer\n    the existing ``[1]_`` over the proposed ``1_``), and ambivalent\n    over the proposed target change.\n\n    That leaves David's problem of wanting to distinguish footnotes\n    and citations - and the only thing I can propose there is that\n    footnotes are numeric or # and citations are not (which, as a\n    human being, I can probably cope with!).\n\nFrom a reply by Paul Moore on 2002-03-01:\n\n    I think the current footnote syntax ``[1]_`` is *exactly* the\n    right balance of distinctness vs unobtrusiveness.  I very\n    definitely don't think this should change.\n\n    On the target change, it doesn't matter much to me.\n\nFrom a further reply by Tony Ibbs on 2002-03-01, referring to the\n\"[1]\" form and actual usage in email:\n\n    Clearly this is a form people are used to, and thus we should\n    consider it strongly (in the same way that the usage of ``*..*``\n    to mean emphasis was taken partly from email practise).\n\n    Equally clearly, there is something \"magical\" for people in the\n    use of a similar form (i.e., ``[1]``) for both footnote reference\n    and footnote target - it seems natural to keep them similar.\n\n    ...\n\n    I think that this established plaintext usage leads me to strongly\n    believe we should retain square brackets at both ends of a\n    footnote.  The markup of the reference end (a single trailing\n    underscore) seems about as minimal as we can get away with.  The\n    markup of the target end depends on how one envisages the thing -\n    if \"..\" means \"I am a target\" (as I tend to see it), then that's\n    good, but one can also argue that the \"_[1]\" syntax has a neat\n    symmetry with the footnote reference itself, if one wishes (in\n    which case \"..\" presumably means \"hidden/special\" as David seems\n    to think, which is why one needs a \"..\" *and* a leading underline\n    for hyperlink targets.\n\nGiven the persuading arguments voiced, we'll leave footnote & footnote\nreference syntax alone.  Except that these discussions gave rise to\nthe \"auto-symbol footnote\" concept, which has been added.

As a standalone\n(non-directive) construct?  (Is the markup ambiguous?)  Add support to\nparts.contents?\n\nNew elements would be required.  Perhaps::\n\n    <!ELEMENT question_list (question_list_item+)>\n    <!ATTLIST question_list\n        numbering  (none | local | global)\n                            #IMPLIED\n        start     NUMBER    #IMPLIED>\n    <!ELEMENT question_list_item (question, answer*)>\n    <!ELEMENT question %text.model;>\n    <!ELEMENT answer (%body.elements;)+>\n\nOriginally I thought of implementing a Q&A list with special syntax::\n\n    Q: What am I?\n\n    A: You are a question-and-answer\n       list.\n\n    Q: What are you?\n\n    A: I am the omniscient \"we\".\n\nWhere each \"Q\" and \"A\" could also be numbered (e.g., \"Q1\").  However,\na simple enumerated or bulleted list will do just fine for syntax.  A\ndirective could treat the list specially; e.g. the first paragraph\ncould be treated as a question, the remainder as the answer (multiple\nanswers could be represented by nested lists).  Without special\nsyntax, this directive becomes low priority.\n\nAs described in the FAQ__, no special syntax or directive is needed\nfor this application.\n\n__ https://docutils.sourceforge.io/FAQ.html\n   #how-can-i-mark-up-a-faq-or-other-list-of-questions-answers\n\n\n--------\n Tabled\n--------\n\nReworking Explicit Markup (Round 2)\n===================================\n\nSee `Reworking Explicit Markup (Round 1)`_ for an earlier discussion.\n\nIn April 2004, a new thread becan on docutils-develop: `Inconsistency\nin RST markup`__.  Several arguments were made; the first argument\nbegat later arguments.  Below, the arguments are paraphrased \"in\nquotes\", with responses.\n\n__ https://thread.gmane.org/gmane.text.docutils.devel/1386\n\n1. References and targets take this form::\n\n       targetname_\n\n       .. _targetname: stuff\n\n   But footnotes, \"which generate links just like targets do\", are\n   written as::\n\n       [1]_\n\n       .. [1] stuff\n\n   \"Footnotes should be written as\"::\n\n       [1]_\n\n       .. _[1]: stuff\n\n   But they're not the same type of animal.  That's not a \"footnote\n   target\", it's a *footnote*.  Being a target is not a footnote's\n   primary purpose (an arguable point).  It just happens to grow a\n   target automatically, for convenience.  Just as a section title::\n\n       Title\n       =====\n\n   isn't a \"title target\", it's a *title*, which happens to grow a\n   target automatically.  The consistency is there, it's just deeper\n   than at first glance.\n\n   Also, \".. [1]\" was chosen for footnote syntax because it closely\n   resembles one form of actual footnote rendering.  \".. _[1]:\" is too\n   verbose; excessive punctuation is required to get the job done.\n\n   For more of the reasoning behind the syntax, see `Problems With\n   StructuredText (Hyperlinks) <problems.html#hyperlinks>`__ and\n   `Reworking Footnotes`_.\n\n2. \"I expect directives to also look like ``.. this:`` [one colon]\n   because that also closely parallels the link and footnote target\n   markup.\"\n\n   There are good reasons for the two-colon syntax:\n\n       Two colons are used after the directive type for these reasons:\n\n       - Two colons are distinctive, and unlikely to be used in common\n         text.\n\n       - Two colons avoids clashes with common comment text like::\n\n             .. Danger: modify at your own risk!\n\n       - If an implementation of reStructuredText does not recognize a\n         directive (i.e., the directive-handler is not installed), a\n         level-3 (error) system message is generated, and the entire\n         directive block (including the directive itself) will be\n         included as a literal block.  Thus \"::\" is a natural choice.\n\n       -- `restructuredtext.html#directives\n       <../../ref/rst/restructuredtext.html#directives>`__\n\n   The last reason is not particularly compelling; it's more of a\n   convenient coincidence or mnemonic.\n\n3. \"Comments always seemed too easy.  I almost never write comments.\n   I'd have no problem writing '.. comment:' in front of my comments.\n   In fact, it would probably be more readable, as comments *should*\n   be set off strongly, because they are very different from normal\n   text.\"\n\n   Many people do use comments though, and some applications of\n   reStructuredText require it.  For example, all reStructuredText\n   PEPs (and this document!) have an Emacs stanza at the bottom, in a\n   comment.  Having to write \".. comment::\" would be very obtrusive.\n\n   Comments *should* be dirt-easy to do.  It should be easy to\n   \"comment out\" a block of text.  Comments in programming languages\n   and other markup languages are invariably easy.\n\n   Any author is welcome to preface their comments with \"Comment:\" or\n   \"Do Not Print\" or \"Note to Editor\" or anything they like.  A\n   \"comment\" directive could easily be implemented.  It might be\n   confused with admonition directives, like \"note\" and \"caution\"\n   though.  In unrelated (and unpublished and unfinished) work, adding\n   a \"comment\" directive as a true document element was considered::\n\n       If structure is necessary, we could use a \"comment\" directive\n       (to avoid nonsensical DTD changes, the \"comment\" directive\n       could produce an untitled topic element).\n\n4. \"One of the goals of reStructuredText is to be *readable* by people\n   who don't know it.  This construction violates that: it is not at\n   all obvious to the uninitiated that text marked by '..' is a\n   comment.  On the other hand, '.. comment:' would be totally\n   transparent.\"\n\n   Totally transparent, perhaps, but also very obtrusive.  Another of\n   `reStructuredText's goals`_ is to be unobtrusive, and\n   \".. comment::\" would violate that.  The goals of reStructuredText\n   are many, and they conflict.  Determining the right set of goals\n   and finding solutions that best fit is done on a case-by-case\n   basis.\n\n   Even readability is has two aspects.  Being readable without any\n   prior knowledge is one.  Being as easily read in raw form as in\n   processed form is the other.  \"..\" may not contribute to the former\n   aspect, but \".. comment::\" would certainly detract from the latter.\n\n   .. _author's note:\n   .. _reStructuredText's goals: ../../ref/rst/introduction.html#goals\n\n5. \"Recently I sent someone an rst document, and they got confused; I\n   had to explain to them that '..' marks comments, *unless* it's a\n   directive, etc...\"\n\n   The explanation of directives *is* roundabout, defining comments in\n   terms of not being other things.  That's definitely a wart.\n\n6. \"Under the current system, a mistyped directive (with ':' instead\n   of '::') will be silently ignored.  This is an error that could\n   easily go unnoticed.\"\n\n   A parser option/setting like \"--comments-on-stderr\" would help.\n\n7. \"I'd prefer to see double-dot-space / command / double-colon as the\n   standard Docutils markup-marker.  It's unusual enough to avoid\n   being accidentally used.  Everything that starts with a double-dot\n   should end with a double-colon.\"\n\n   That would increase the punctuation verbosity of some constructs\n   considerably.\n\n8. Edward Loper proposed the following plan for backwards\n   compatibility:\n\n       1. \".. foo\" will generate a deprecation warning to stderr, and\n          nothing in the output (no system messages).\n       2. \".. foo: bar\" will be treated as a directive foo.  If there\n          is no foo directive, then do the normal error output.\n       3. \".. foo:: bar\" will generate a deprecation warning to\n          stderr, and be treated as a directive.  Or leave it valid?\n\n       So some existing documents might start printing deprecation\n       warnings, but the only existing documents that would *break*\n       would be ones that say something like::\n\n           .. warning: this should be a comment\n\n       instead of::\n\n           .. warning:: this should be a comment\n\n       Here, we're trading fairly common a silent error (directive\n       falsely treated as a comment) for a fairly uncommon explicitly\n       flagged error (comment falsely treated as directive).  To make\n       things even easier, we could add a sentence to the\n       unknown-directive error.  Something like \"If you intended to\n       create a comment, please use '.. comment:' instead\".\n\nOn one hand, I understand and sympathize with the points raised.  On\nthe other hand, I think the current syntax strikes the right balance\n(but I acknowledge a possible lack of objectivity).  On the gripping\nhand, the comment and directive syntax has become well established, so\neven if it's a wart, it may be a wart we have to live with.\n\nMaking any of these changes would cause a lot of breakage or at least\ndeprecation warnings.  I'm not sure the benefit is worth the cost.\n\nFor now, we'll treat this as an unresolved legacy issue.\n\n\n-------\n To Do\n-------\n\nNested Inline Markup\n====================\n\nThese are collected notes on a long-discussed issue.  The original\nmailing list messages should be referred to for details.\n\n* In a 2001-10-31 discussion I wrote:\n\n      Try, for example, `Ed Loper's 2001-03-21 post`_, which details\n      some rules for nested inline markup. I think the complexity is\n      prohibitive for the marginal benefit. (And if you can understand\n      that tree without going mad, you're a better man than I. ;-)\n\n      Inline markup is already fragile. Allowing nested inline markup\n      would only be asking for trouble IMHO. If it proves absolutely\n      necessary, it can be added later. The rules for what can appear\n      inside what must be well thought out first though.\n\n      .. _Ed Loper's 2001-03-21 post:\n         https://mail.python.org/pipermail/doc-sig/2001-March/001487.html\n\n      -- https://mail.python.org/pipermail/doc-sig/2001-October/002354.html\n\n* In a 2001-11-09 Doc-SIG post, I wrote:\n\n      The problem is that in the\n      what-you-see-is-more-or-less-what-you-get markup language that\n      is reStructuredText, the symbols used for inline markup (\"*\",\n      \"**\", \"`\", \"``\", etc.) may preclude nesting.\n\n  I've rethought this position.  Nested markup is not precluded, just\n  tricky.  People and software parse \"double and 'single' quotes\" all\n  the time.  Continuing,\n\n      I've thought over how we might implement nested inline\n      markup. The first algorithm (\"first identify the outer inline\n      markup as we do now, then recursively scan for nested inline\n      markup\") won't work; counterexamples were given in my `last post\n      <https://mail.python.org/pipermail/doc-sig/2001-November/002363.html>`__.\n\n      The second algorithm makes my head hurt::\n\n          while 1:\n              scan for start-string\n              if found:\n                  push on stack\n                  scan for start or end string\n                  if new start string found:\n                      recurse\n                  elif matching end string found:\n                      pop stack\n                  elif non-matching end string found:\n                      if its a markup error:\n                          generate warning\n                      elif the initial start-string was misinterpreted:\n                          # e.g. in this case: ***strong** in emphasis*\n                          restart with the other interpretation\n                          # but it might be several layers back ...\n              ...\n\n      This is similar to how the parser does section title\n      recognition, but sections are much more regular and\n      deterministic.\n\n      Bottom line is, I don't think the benefits are worth the effort,\n      even if it is possible. I'm not going to try to write the code,\n      at least not now. If somebody codes up a consistent, working,\n      general solution, I'll be happy to consider it.\n\n      -- https://mail.python.org/pipermail/doc-sig/2001-November/002388.html\n\n* In a `2003-05-06 Docutils-Users post`__ Paul Tremblay proposed a new\n  syntax to allow for easier nesting.  It eventually evolved into\n  this::\n\n      :role:[inline text]\n\n  The duplication with the existing interpreted text syntax is\n  problematic though.\n\n  __ https://article.gmane.org/gmane.text.docutils.user/317\n\n* Could the parser be extended to parse nested interpreted text? ::\n\n      :emphasis:`Some emphasized text with :strong:`some more\n      emphasized text` in it and **perhaps** :reference:`a link``\n\n* In a `2003-06-18 Docutils-Develop post`__, Mark Nodine reported on\n  his implementation of a form of nested inline markup in his\n  Perl-based parser (unpublished).  He brought up some interesting\n  ideas.  The implementation was flawed, however, by the change in\n  semantics required for backslash escapes.\n\n  __ https://article.gmane.org/gmane.text.docutils.devel/795\n\n* Docutils-develop threads between David Abrahams, David Goodger, and\n  Mark Nodine (beginning 2004-01-16__ and 2004-01-19__) hashed out\n  many of the details of a potentially successful implementation, as\n  described below.  David Abrahams checked in code to the \"nesting\"\n  branch of CVS, awaiting thorough review.\n\n  __ https://thread.gmane.org/gmane.text.docutils.devel/1102\n  __ https://thread.gmane.org/gmane.text.docutils.devel/1125\n\nIt may be possible to accomplish nested inline markup in general with\na more powerful inline markup parser.  There may be some issues, but\nI'm not averse to the idea of nested inline markup in general.  I just\ndon't have the time or inclination to write a new parser now.  Of\ncourse, a good patch would be welcome!\n\nI envisage something like this.  Explicit-role interpreted text must\nbe nestable.  Prefix-based is probably preferred, since suffix-based\nwill look like inline literals::\n\n    ``text`:role1:`:role2:\n\nBut it can be disambiguated, so it ought to be left up to the author::\n\n    `\\ `text`:role1:`:role2:\n\nIn addition, other forms of inline markup may be nested if\nunambiguous::\n\n    *emphasized ``literal`` and |substitution ref| and link_*\n\nIOW, the parser ought to be as permissive as possible.\n\n\nIndex Entries & Indexes\n=======================\n\nWere I writing a book with an index, I guess I'd need two\ndifferent kinds of index targets: inline/implicit and\nout-of-line/explicit.  For example::\n\n    In this `paragraph`:index:, several words are being\n    `marked`:index: inline as implicit `index`:index:\n    entries.\n\n    .. index:: markup\n    .. index:: syntax\n\n    The explicit index directives above would refer to\n    this paragraph.  It might also make sense to allow multiple\n    entries in an ``index`` directive:\n\n    .. index::\n        markup\n        syntax\n\nThe words \"paragraph\", \"marked\", and \"index\" would become index\nentries pointing at the words in the first paragraph.  The index\nentry words appear verbatim in the text.  (Don't worry about the\nugly \":index:\" part; if indexing is the only/main application of\ninterpreted text in your documents, it can be implicit and\nomitted.)  The two directives provide manual indexing, where the\nindex entry words (\"markup\" and \"syntax\") do not appear in the\nmain text.  We could combine the two directives into one::\n\n    .. index:: markup; syntax\n\nSemicolons instead of commas because commas could *be* part of the\nindex target, like::\n\n    .. index:: van Rossum, Guido\n\nAnother reason for index directives is because other inline markup\nwouldn't be possible within inline index targets.\n\nSometimes index entries have multiple levels.  Given::\n\n    .. index:: statement syntax: expression statements\n\nIn a hypothetical index, combined with other entries, it might\nlook like this::\n\n    statement syntax\n        expression statements ..... 56\n        assignment ................ 57\n        simple statements ......... 58\n        compound statements ....... 60\n\nInline multi-level index targets could be done too.  Perhaps\nsomething like::\n\n    When dealing with `expression statements <statement syntax:>`,\n    we must remember ...\n\nThe opposite sense could also be possible::\n\n    When dealing with `index entries <:multi-level>`, there are\n    many permutations to consider.\n\nAlso \"see / see also\" index entries.\n\nGiven::\n\n    Here's a paragraph.\n\n    .. index:: paragraph\n\n(The \"index\" directive above actually targets the *preceding*\nobject.)  The directive should produce something like this XML::\n\n    <paragraph>\n    <index_entry text=\"paragraph\"/>\n    Here's a paragraph.\n    </paragraph>\n\nThis kind of content model would also allow true inline\nindex-entries::\n\n    Here's a `paragraph`:index:.\n\nIf the \"index\" role were the default for the application, it could be\ndropped::\n\n    Here's a `paragraph`.\n\nBoth of these would result in this XML::\n\n    <paragraph>\n    Here's a <index_entry>paragraph</index_entry>.\n    </paragraph>\n\n\nfrom 2002-06-24 docutils-develop posts\n--------------------------------------\n\n    If all of your index entries will appear verbatim in the text,\n    this should be sufficient.  If not (e.g., if you want \"Van Rossum,\n    Guido\" in the index but \"Guido van Rossum\" in the text), we'll\n    have to figure out a supplemental mechanism, perhaps using\n    substitutions.\n\nI've thought a bit more on this, and I came up with two possibilities:\n\n1. Using interpreted text, embed the index entry text within the\n   interpreted text::\n\n       ... by `Guido van Rossum [Van Rossum, Guido]` ...\n\n   The problem with this is obvious: the text becomes cluttered and\n   hard to read.  The processed output would drop the text in\n   brackets, which goes against the spirit of interpreted text.\n\n2. Use substitutions::\n\n       ... by |Guido van Rossum| ...\n\n       .. |Guido van Rossum| index:: Van Rossum, Guido\n\n   A problem with this is that each substitution definition must have\n   a unique name.  A subsequent ``.. |Guido van Rossum| index:: BDFL``\n   would be illegal.  Some kind of anonymous substitution definition\n   mechanism would be required, but I think that's going too far.\n\nBoth of these alternatives are flawed.  Any other ideas?\n\n\n-------------------\n ... Or Not To Do?\n-------------------\n\nThis is the realm of the possible but questionably probable.  These\nideas are kept here as a record of what has been proposed, for\nposterity and in case any of them prove to be useful.\n\n\nCompound Enumerated Lists\n=========================\n\nAllow for compound enumerators, such as \"1.1.\" or \"1.a.\" or \"1(a)\", to\nallow for nested enumerated lists without indentation?\n\n\nIndented Lists\n==============\n\nAllow for variant styles by interpreting indented lists as if they\nweren't indented?  For example, currently the list below will be\nparsed as a list within a block quote::\n\n    paragraph\n\n      * list item 1\n      * list item 2\n\nBut a lot of people seem to write that way, and HTML browsers make it\nlook as if that's the way it should be.  The parser could check the\ncontents of block quotes, and if they contain only a single list,\nremove the block quote wrapper.  There would be two problems:\n\n1. What if we actually *do* want a list inside a block quote?\n\n2. What if such a list comes immediately after an indented construct,\n   such as a literal block?\n\nBoth could be solved using empty comments (problem 2 already exists\nfor a block quote after a literal block).  But that's a hack.\n\nPerhaps a runtime setting, allowing or disabling this convenience,\nwould be appropriate.  But that raises issues too:\n\n    User A, who writes lists indented (and their config file is set up\n    to allow it), sends a file to user B, who doesn't (and their\n    config file disables indented lists).  The result of processing by\n    the two users will be different.\n\nIt may seem minor, but it adds ambiguity to the parser, which is bad.\n\nSee the `Doc-SIG discussion starting 2001-04-18`__ with Ed Loper's\n\"Structuring: a summary; and an attempt at EBNF\", item 4 (and\nfollow-ups, here__ and here__).  Also `docutils-users, 2003-02-17`__\nand `beginning 2003-08-04`__.\n\n__ https://mail.python.org/pipermail/doc-sig/2001-April/001776.html\n__ https://mail.python.org/pipermail/doc-sig/2001-April/001789.html\n__ https://mail.python.org/pipermail/doc-sig/2001-April/001793.html\n__ https://sourceforge.net/mailarchive/message.php?msg_id=3838913\n__ https://sf.net/mailarchive/forum.php?thread_id=2957175&forum_id=11444\n\n\nSloppy Indentation of List Items\n================================\n\nPerhaps the indentation shouldn't be so strict.  Currently, this is\nrequired::\n\n    1. First line,\n       second line.\n\nAnything wrong with this? ::\n\n    1. First line,\n     second line.\n\nProblem? ::\n\n    1. First para.\n\n       Block quote.  (no good: requires some indent relative to first\n       para)\n\n     Second Para.\n\n    2. Have to carefully define where the literal block ends::\n\n         Literal block\n\n       Literal block?\n\nHmm...  Non-strict indentation isn't such a good idea.\n\n\nLazy Indentation of List Items\n==============================\n\nAnother approach: Going back to the first draft of reStructuredText\n(2000-11-27 post to Doc-SIG)::\n\n    - This is the fourth item of the main list (no blank line above).\n    The second line of this item is not indented relative to the\n    bullet, which precludes it from having a second paragraph.\n\nChange that to *require* a blank line above and below, to reduce\nambiguity.  This \"loosening\" may be added later, once the parser's\nbeen nailed down.  However, a serious drawback of this approach is to\nlimit the content of each list item to a single paragraph.\n\n\nDavid's Idea for Lazy Indentation\n---------------------------------\n\nConsider a paragraph in a word processor.  It is a single logical line\nof text which ends with a newline, soft-wrapped arbitrarily at the\nright edge of the page or screen.  We can think of a plaintext\nparagraph in the same way, as a single logical line of text, ending\nwith two newlines (a blank line) instead of one, and which may contain\narbitrary line breaks (newlines) where it was accidentally\nhard-wrapped by an application.  We can compensate for the accidental\nhard-wrapping by \"unwrapping\" every unindented second and subsequent\nline.  The indentation of the first line of a paragraph or list item\nwould determine the indentation for the entire element.  Blank lines\nwould be required between list items when using lazy indentation.\n\nThe following example shows the lazy indentation of multiple body\nelements::\n\n    - This is the first paragraph\n    of the first list item.\n\n      Here is the second paragraph\n    of the first list item.\n\n    - This is the first paragraph\n    of the second list item.\n\n      Here is the second paragraph\n    of the second list item.\n\nA more complex example shows the limitations of lazy indentation::\n\n    - This is the first paragraph\n    of the first list item.\n\n      Next is a definition list item:\n\n      Term\n          Definition.  The indentation of the term is\n    required, as is the indentation of the definition's\n    first line.\n\n          When the definition extends to more than\n    one line, lazy indentation may occur.  (This is the second\n    paragraph of the definition.)\n\n    - This is the first paragraph\n    of the second list item.\n\n      - Here is the first paragraph of\n    the first item of a nested list.\n\n      So this paragraph would be outside of the nested list,\n    but inside the second list item of the outer list.\n\n    But this paragraph is not part of the list at all.\n\nAnd the ambiguity remains::\n\n    - Look at the hyphen at the beginning of the next line\n    - is it a second list item marker, or a dash in the text?\n\n    Similarly, we may want to refer to numbers inside enumerated\n    lists:\n\n    1. How many socks in a pair? There are\n    2. How many pants in a pair? Exactly\n    1. Go figure.\n\nLiteral blocks and block quotes would still require consistent\nindentation for all their lines.  For block quotes, we might be able\nto get away with only requiring that the first line of each contained\nelement be indented.  For example::\n\n    Here's a paragraph.\n\n        This is a paragraph inside a block quote.\n    Second and subsequent lines need not be indented at all.\n\n        - A bullet list inside\n    the block quote.\n\n          Second paragraph of the\n    bullet list inside the block quote.\n\nAlthough feasible, this form of lazy indentation has problems.  The\ndocument structure and hierarchy is not obvious from the indentation,\nmaking the source plaintext difficult to read.  This will also make\nkeeping track of the indentation while writing difficult and\nerror-prone.  However, these problems may be acceptable for Wikis and\nemail mode, where we may be able to rely on less complex structure\n(few nested lists, for example).\n\n\nMultiple Roles in Interpreted Text\n==================================\n\nIn reStructuredText, inline markup cannot be nested (yet; `see\nabove`__).  This also applies to interpreted text.  In order to\nsimultaneously combine multiple roles for a single piece of text, a\nsyntax extension would be necessary.  Ideas:\n\n1. Initial idea::\n\n       `interpreted text`:role1,role2:\n\n2. Suggested by Jason Diamond::\n\n       `interpreted text`:role1:role2:\n\nIf a document is so complex as to require nested inline markup,\nperhaps another markup system should be considered.  By design,\nreStructuredText does not have the flexibility of XML.\n\n__ `Nested Inline Markup`_\n\n\nParameterized Interpreted Text\n==============================\n\nIn some cases it may be expedient to pass parameters to interpreted\ntext, analogous to function calls.  Ideas:\n\n1. Parameterize the interpreted text role itself (suggested by Jason\n   Diamond)::\n\n       `interpreted text`:role1(foo=bar):\n\n   Positional parameters could also be supported::\n\n       `CSS`:acronym(Cascading Style Sheets): is used for HTML, and\n       `CSS`:acronym(Content Scrambling System): is used for DVDs.\n\n   Technical problem: current interpreted text syntax does not\n   recognize roles containing whitespace.  Design problem: this smells\n   like programming language syntax, but reStructuredText is not a\n   programming language.\n\n2. Put the parameters inside the interpreted text::\n\n       `CSS (Cascading Style Sheets)`:acronym: is used for HTML, and\n       `CSS (Content Scrambling System)`:acronym: is used for DVDs.\n\n   Although this could be defined on an individual basis (per role),\n   we ought to have a standard.  Hyperlinks with embedded URIs already\n   use angle brackets; perhaps they could be used here too::\n\n       `CSS <Cascading Style Sheets>`:acronym: is used for HTML, and\n       `CSS <Content Scrambling System>`:acronym: is used for DVDs.\n\n   Do angle brackets connote URLs too much for this to be acceptable?\n   How about the \"tag\" connotation -- does it save them or doom them?\n\n3. `Nested inline markup`_ could prove useful here::\n\n       `CSS :def:`Cascading Style Sheets``:acronym: is used for HTML,\n       and `CSS :def:`Content Scrambling System``:acronym: is used for\n       DVDs.\n\n   Inline markup roles could even define the default roles of nested\n   inline markup, allowing this cleaner syntax::\n\n       `CSS `Cascading Style Sheets``:acronym: is used for HTML, and\n       `CSS `Content Scrambling System``:acronym: is used for DVDs.\n\nDoes this push inline markup too far?  Readability becomes a serious\nissue.  Substitutions may provide a better alternative (at the expense\nof verbosity and duplication) by pulling the details out of the text\nflow::\n\n    |CSS| is used for HTML, and |CSS-DVD| is used for DVDs.\n\n    .. |CSS| acronym:: Cascading Style Sheets\n    .. |CSS-DVD| acronym:: Content Scrambling System\n       :text: CSS\n\n----------------------------------------------------------------------\n\nThis whole idea may be going beyond the scope of reStructuredText.\nDocuments requiring this functionality may be better off using XML or\nanother markup system.\n\nThis argument comes up regularly when pushing the envelope of\nreStructuredText syntax.  I think it's a useful argument in that it\nprovides a check on creeping featurism.  In many cases, the resulting\nverbosity produces such unreadable plaintext that there's a natural\ndesire *not* to use it unless absolutely necessary.  It's a matter of\nfinding the right balance.\n\n\nSyntax for Interpreted Text Role Bindings\n=========================================\n\nThe following syntax (idea from Jeffrey C. Jacobs) could be used to\nassociate directives with roles::\n\n    .. :rewrite: class:: rewrite\n\n    `She wore ribbons in her hair and it lay with streaks of\n    grey`:rewrite:\n\nThe syntax is similar to that of substitution declarations, and the\ndirective/role association may resolve implementation issues.  The\nsemantics, ramifications, and implementation details would need to be\nworked out.\n\nThe example above would implement the \"rewrite\" role as adding a\n``class=\"rewrite\"`` attribute to the interpreted text (\"inline\"\nelement).  The stylesheet would then pick up on the \"class\" attribute\nto do the actual formatting.\n\nThe advantage of the new syntax would be flexibility.  Uses other than\n\"class\" may present themselves.  The disadvantage is complexity:\nhaving to implement new syntax for a relatively specialized operation,\nand having new semantics in existing directives (\"class::\" would do\nsomething different).\n\nThe `\"role\" directive`__ has been implemented.\n\n__ ../../ref/rst/directives.html#role\n\n\nCharacter Processing\n====================\n\nSeveral people have suggested adding some form of character processing\nto reStructuredText:\n\n* Some sort of automated replacement of ASCII sequences:\n\n  - ``--`` to em-dash (or ``--`` to en-dash, and ``---`` to em-dash).\n  - Convert quotes to curly quote entities.  (Essentially impossible\n    for HTML?  Unnecessary for TeX.)\n  - Various forms of ``:-)`` to smiley icons.\n  - ``\"\\ \"`` to &nbsp;.  Problem with line-wrapping though: it could\n    end up escaping the newline.\n  - Escaped newlines to <BR>.\n  - Escaped period or quote or dash as a disappearing catalyst to\n    allow character-level inline markup?\n\n* XML-style character entities, such as \"&copy;\" for the copyright\n  symbol.\n\nDocutils has no need of a character entity subsystem.  Supporting\nUnicode and text encodings, character entities should be directly\nrepresented in the text: a copyright symbol should be represented by\nthe copyright symbol character.  If this is not possible in an\nauthoring environment, a pre-processing stage can be added, or a table\nof substitution definitions can be devised.\n\nA \"unicode\" directive has been implemented to allow direct\nspecification of esoteric characters.  In combination with the\nsubstitution construct, \"include\" files defining common sets of\ncharacter entities can be defined and used.  `A set of character\nentity set definition files have been defined`__ (`tarball`__).\nThere's also `a description and instructions for use`__.\n\n__ https://docutils.sourceforge.io/tmp/charents/\n__ https://docutils.sourceforge.io/tmp/charents.tgz\n__ https://docutils.sourceforge.io/tmp/charents/README.html\n\nTo allow for `character-level inline markup`_, a limited form of\ncharacter processing has been added to the spec and parser: escaped\nwhitespace characters are removed from the processed document.  Any\nfurther character processing will be of this functional type, rather\nthan of the character-encoding type.\n\n.. _character-level inline markup:\n   ../../ref/rst/restructuredtext.html#character-level-inline-markup\n\n* Directive idea::\n\n      .. text-replace:: \"pattern\" \"replacement\"\n\n  - Support Unicode \"U+XXXX\" codes.\n  - Support regexps, perhaps with alternative \"regexp-replace\"\n    directive.\n  - Flags for regexps; \":flags:\" option, or individuals.\n  - Specifically, should the default be case-sensistive or\n    -insensitive?\n\n\nPage Or Line Breaks\n===================\n\n* Should ^L (or something else in reST) be defined to mean\n  force/suggest page breaks in whatever output we have?\n\n  A \"break\" or \"page-break\" directive would be easy to add.  A new\n  doctree element would be required though (perhaps \"break\").  The\n  final behavior would be up to the Writer.  The directive argument\n  could be one of page/column/recto/verso for added flexibility.\n\n  Currently ^L (Python's ``\\f``) characters are treated as whitespace.\n  They're converted to single spaces, actually, as are vertical tabs\n  (^K, Python's ``\\v``).  It would be possible to recognize form feeds\n  as markup, but it requires some thought and discussion first.  Are\n  there any downsides?  Many editing environments do not allow the\n  insertion of control characters.  Will it cause any harm?  It would\n  be useful as a shorthand for the directive.\n\n  It's common practice to use ^L before Emacs \"Local Variables\"\n  lists::\n\n      ^L\n      ..\n         Local Variables:\n         mode: indented-text\n         indent-tabs-mode: nil\n         sentence-end-double-space: t\n         fill-column: 70\n         End:\n\n  These are already present in many PEPs and Docutils project\n  documents.  From the Emacs manual (info):\n\n      A \"local variables list\" goes near the end of the file, in the\n      last page.  (It is often best to put it on a page by itself.)\n\n  It would be unfortunate if this construct caused a final blank page\n  to be generated (for those Writers that recognize the page breaks).\n  We'll have to add a transform that looks for a \"break\" plus zero or\n  more comments at the end of a document, and removes them.\n\n  Probably a bad idea because there is no such thing as a page in a\n  generic document format.\n\n* Could the \"break\" concept above be extended to inline forms?\n  E.g. \"^L\" in the middle of a sentence could cause a line break.\n  Only recognize it at the end of a line (i.e., ``\\f\\n``)?\n\n  Or is formfeed inappropriate?  Perhaps vertical tab (``\\v``), but\n  even that's a stretch.  Can't use carriage returns, since they're\n  commonly used for line endings.\n\n  Probably a bad idea as well because we do not want to use control\n  characters for well-readable and well-writable markup, and after all\n  we have the line block syntax for line breaks.\n\n\nSuperscript Markup\n==================\n\nAdd ``^superscript^`` inline markup?  The only common non-markup uses\nof \"^\" I can think of are as short hand for \"superscript\" itself and\nfor describing control characters (\"^C to cancel\").  The former\nsupports the proposed syntax, and it could be argued that the latter\nought to be literal text anyhow (e.g. \"``^C`` to cancel\").\n\nHowever, superscripts are seldom needed, and new syntax would break\nexisting documents.  When it's needed, the ``:superscript:``\n(``:sup:``) role can we used as well.\n\n\nCode Execution\n==============\n\nAdd the following directives?\n\n- \"exec\": Execute Python code & insert the results.  Call it\n  \"python\" to allow for other languages?\n\n- \"system\": Execute an ``os.system()`` call, and insert the results\n  (possibly as a literal block).  Definitely dangerous!  How to make\n  it safe?  Perhaps such processing should be left outside of the\n  document, in the user's production system (a makefile or a script or\n  whatever).  Or, the directive could be disabled by default and only\n  enabled with an explicit command-line option or config file setting.\n  Even then, an interactive prompt may be useful, such as:\n\n      The file.txt document you are processing contains a \"system\"\n      directive requesting that the ``sudo rm -rf /`` command be\n      executed.  Allow it to execute?  (y/N)\n\n- \"eval\": Evaluate an expression & insert the text.  At parse\n  time or at substitution time?  Dangerous?  Perhaps limit to canned\n  macros; see text.date_.\n\n  .. _text.date: ../todo.html#text-date\n\nIt's too dangerous (or too complicated in the case of \"eval\").  We do\nnot want to have such things in the core.\n\n\n``encoding`` Directive\n======================\n\nAdd an \"encoding\" directive to specify the character encoding of the\ninput data?  Not a good idea for the following reasons:\n\n- When it sees the directive, the parser will already have read the\n  input data, and encoding determination will already have been done.\n\n- If a file with an \"encoding\" directive is edited and saved with\n  a different encoding, the directive may cause data corruption.\n\n\nSupport for Annotations\n=======================\n\nAdd an \"annotation\" role, as the equivalent of the HTML \"title\"\nattribute?  This is secondary information that may \"pop up\" when the\npointer hovers over the main text.  A corresponding directive would be\nrequired to associate annotations with the original text (by name, or\npositionally as in anonymous targets?).\n\nThere have not been many requests for such feature, though.  Also,\ncluttering WYSIWYG plaintext with annotations may not seem like a good\nidea, and there is no \"tool tip\" in formats other than HTML.\n\n\n``term`` Role\n=============\n\nAdd a \"term\" role for unfamiliar or specialized terminology?  Probably\nnot; there is no real use case, and emphasis is enough for most cases.\n\n\nObject references\n=================\n\nWe need syntax for `object references`_.\n\n  - Parameterized substitutions?  For example::\n\n        See |figure (figure name)| on |page (figure name)|.\n\n        .. |figure (name)| figure-ref:: (name)\n        .. |page (name)| page-ref:: (name)\n\n    The result would be::\n\n        See figure 3.11 on page 157.\n\n    But this would require substitution directives to be processed at\n    reference-time, not at definition-time as they are now.  Or,\n    perhaps the directives could just leave ``pending`` elements\n    behind, and the transforms do the work?  How to pass the data\n    through? Too complicated. Use interpreted text roles.\n\n.. _object references:\n   ../todo.html#object-numbering-and-object-references\n\n\f\n..\n   Local Variables:\n   mode: indented-text\n   indent-tabs-mode: nil\n   sentence-end-double-space: t\n   fill-column: 70\n   End:\n"

    "content": "==============================\n Problems With StructuredText\n==============================\n:Author: David Goodger\n:Contact: docutils-develop@lists.sourceforge.net\n:Revision: $Revision$\n:Date: $Date$\n:Copyright: This document has been placed in the public domain.\n\nThere are several problems, unresolved issues, and areas of\ncontroversy within StructuredText_ (Classic and Next Generation).  In\norder to resolve all these issues, this analysis brings all of the\nissues out into the open, enumerates all the alternatives, and\nproposes solutions to be incorporated into the reStructuredText_\nspecification.\n\n\n.. contents::\n\n\nFormal Specification\n====================\n\nThe description in the original StructuredText.py has been criticized\nfor being vague.  For practical purposes, \"the code *is* the spec.\"\nTony Ibbs has been working on deducing a `detailed description`_ from\nthe documentation and code of StructuredTextNG_.  Edward Loper's\nSTMinus_ is another attempt to formalize a spec.\n\nFor this kind of a project, the specification should always precede\nthe code.  Otherwise, the markup is a moving target which can never be\nadopted as a standard.  Of course, a specification may be revised\nduring lifetime of the code, but without a spec there is no visible\ncontrol and thus no confidence.\n\n\nUnderstanding and Extending the Code\n====================================\n\nThe original StructuredText_ is a dense mass of sparsely commented\ncode and inscrutable regular expressions.  It was not designed to be\nextended and is very difficult to understand.  StructuredTextNG_ has\nbeen designed to allow input (syntax) and output extensions, but its\ndocumentation (both internal [comments & docstrings], and external) is\ninadequate for the complexity of the code itself.\n\nFor reStructuredText to become truly useful, perhaps even part of\nPython's standard library, it must have clear, understandable\ndocumentation and implementation code.  For the implementation of\nreStructuredText to be taken seriously, it must be a sterling example\nof the potential of docstrings; the implementation must practice what\nthe specification preaches.\n\n\nSection Structure via Indentation\n=================================\n\nSetext_ required that body text be indented by 2 spaces.  The original\nStructuredText_ and StructuredTextNG_ require that section structure\nbe indicated through indentation, as \"inspired by Python\".  For\ncertain structures with a very limited, local extent (such as lists,\nblock quotes, and literal blocks), indentation naturally indicates\nstructure or hierarchy.  For sections (which may have a very large\nextent), structure via indentation is unnecessary, unnatural and\nambiguous.  Rather, the syntax of the section title *itself* should\nindicate that it is a section title.\n\nThe original StructuredText states that \"A single-line paragraph whose\nimmediately succeeding paragraphs are lower level is treated as a\nheader.\" Requiring indentation in this way is:\n\n- Unnecessary.  The vast majority of docstrings and standalone\n  documents will have no more than one level of section structure.\n  Requiring indentation for such docstrings is unnecessary and\n  irritating.\n\n- Unnatural.  Most published works use title style (type size, face,\n  weight, and position) and/or section/subsection numbering rather\n  than indentation to indicate hierarchy.  This is a tradition with a\n  very long history.\n\n- Ambiguous.  A StructuredText header is indistinguishable from a\n  one-line paragraph followed by a block quote (precluding the use of\n  block quotes).  Enumerated section titles are ambiguous (is it a\n  header? is it a list item?).  Some additional adornment must be\n  required to confirm the line's role as a title, both to a parser and\n  to the human reader of the source text.\n\nPython's use of significant whitespace is a wonderful (if not\noriginal) innovation, however requiring indentation in ordinary\nwritten text is hypergeneralization.\n\nreStructuredText_ indicates section structure through title adornment\nstyle (as exemplified by this document).  This is far more natural.\nIn fact, it is already in widespread use in plain text documents,\nincluding in Python's standard distribution (such as the toplevel\nREADME_ file).\n\n\nCharacter Escaping Mechanism\n============================\n\nNo matter what characters are chosen for markup, some day someone will\nwant to write documentation *about* that markup or using markup\ncharacters in a non-markup context.  Therefore, any complete markup\nlanguage must have an escaping or encoding mechanism.  For a\nlightweight markup system, encoding mechanisms like SGML/XML's '&ast;'\nare out.  So an escaping mechanism is in.  However, with carefully\nchosen markup, it should be necessary to use the escaping mechanism\nonly infrequently.\n\nreStructuredText_ needs an escaping mechanism: a way to treat\nmarkup-significant characters as the characters themselves.  Currently\nthere is no such mechanism (although ZWiki uses '!').  What are the\ncandidates?\n\n1. ``!``\n   (http://www.zope.org/DevHome/Members/jim/StructuredTextWiki/NGEscaping)\n2. ``\\``\n3. ``~``\n4. doubling of characters\n\nThe best choice for this is the backslash (``\\``).  It's \"the single\nmost popular escaping character in the world!\", therefore familiar and\nunsurprising.  Since characters only need to be escaped under special\ncircumstances, which are typically those explaining technical\nprogramming issues, the use of the backslash is natural and\nunderstandable.  Python docstrings can be raw (prefixed with an 'r',\nas in 'r\"\"'), which would obviate the need for gratuitous doubling-up\nof backslashes.\n\n(On 2001-03-29 on the Doc-SIG mailing list, GvR endorsed backslash\nescapes, saying, \"'nuff said.  Backslash it is.\" Although neither\nlegally binding nor irrevocable nor any kind of guarantee of anything,\nit is a good sign.)\n\nThe rule would be: An unescaped backslash followed by any markup\ncharacter escapes the character.  The escaped character represents the\ncharacter itself, and is prevented from playing a role in any markup\ninterpretation.  The backslash is removed from the output.  A literal\nbackslash is represented by an \"escaped backslash,\" two backslashes in\na row.\n\nA carefully constructed set of recognition rules for inline markup\nwill obviate the need for backslash-escapes in almost all cases; see\n`Delimitation of Inline Markup`_ below.\n\nWhen an expression (requiring backslashes and other characters used\nfor markup) becomes too complicated and therefore unreadable, a\nliteral block may be used instead.  Inside literal blocks, no markup\nis recognized, therefore backslashes (for the purpose of escaping\nmarkup) become unnecessary.\n\nWe could allow backslashes preceding non-markup characters to remain\nin the output.  This would make describing regular expressions and\nother uses of backslashes easier.  However, this would complicate the\nmarkup rules and would be confusing.\n\n\nBlank Lines in Lists\n====================\n\nOft-requested in Doc-SIG (the earliest reference is dated 1996-08-13)\nis the ability to write lists without requiring blank lines between\nitems.  In docstrings, space is at a premium.  Authors want to convey\ntheir API or usage information in as compact a form as possible.\nStructuredText_ requires blank lines between all body elements,\nincluding list items, even when boundaries are obvious from the markup\nitself.\n\nIn reStructuredText, blank lines are optional between list items.\nHowever, in order to eliminate ambiguity, a blank line is required\nbefore the first list item and after the last.  Nested lists also\nrequire blank lines before the list start and after the list end.\n\n\nBullet List Markup\n==================\n\nStructuredText_ includes 'o' as a bullet character.  This is dangerous\nand counter to the language-independent nature of the markup.  There\nare many languages in which 'o' is a word.  For example, in Spanish::\n\n    Llamame a la casa\n    o al trabajo.\n\n    (Call me at home or at work.)\n\nAnd in Japanese (when romanized)::\n\n    Senshuu no doyoubi ni tegami\n    o kakimashita.\n\n    ([I] wrote a letter on Saturday last week.)\n\nIf a paragraph containing an 'o' word wraps such that the 'o' is the\nfirst text on a line, or if a paragraph begins with such a word, it\ncould be misinterpreted as a bullet list.\n\nIn reStructuredText_, 'o' is not used as a bullet character.  '-',\n'*', and '+' are the possible bullet characters.\n\n\nEnumerated List Markup\n======================\n\nStructuredText enumerated lists are allowed to begin with numbers and\nletters followed by a period or right-parenthesis, then whitespace.\nThis has surprising consequences for writing styles.  For example,\nthis is recognized as an enumerated list item by StructuredText::\n\n    Mr. Creosote.\n\nPeople will write enumerated lists in all different ways.  It is folly\nto try to come up with the \"perfect\" format for an enumerated list,\nand limit the docstring parser's recognition to that one format only.\n\nRather, the parser should recognize a variety of enumerator styles.\nIt is also recommended that the enumerator of the first list item be\nordinal-1 ('1', 'A', 'a', 'I', or 'i'), as output formats may not be\nable to begin a list at an arbitrary enumeration.\n\nAn initial idea was to require two or more consistent enumerated list\nitems in a row.  This idea proved impractical and was dropped.  In\npractice, the presence of a proper enumerator is enough to reliably\nrecognize an enumerated list item; any ambiguities are reported by the\nparser.  Here's the original idea for posterity:\n\n    The parser should recognize a variety of enumerator styles, mark\n    each block as a potential enumerated list item (PELI), and\n    interpret the enumerators of adjacent PELIs to decide whether they\n    make up a consistent enumerated list.\n\n    If a PELI is labeled with a \"1.\", and is immediately followed by a\n    PELI labeled with a \"2.\", we've got an enumerated list.  Or \"(A)\"\n    followed by \"(B)\".  Or \"i)\" followed by \"ii)\", etc.  The chances\n    of accidentally recognizing two adjacent and consistently labeled\n    PELIs, are acceptably small.\n\n    For an enumerated list to be recognized, the following must be\n    true:\n\n    - the list must consist of multiple adjacent list items (2 or\n      more)\n    - the enumerators must all have the same format\n    - the enumerators must be sequential\n\n\nDefinition List Markup\n======================\n\nStructuredText uses ' -- ' (whitespace, two hyphens, whitespace) on\nthe first line of a paragraph to indicate a definition list item.  The\n' -- ' serves to separate the term (on the left) from the definition\n(on the right).\n\nMany people use ' -- ' as an em-dash in their text, conflicting with\nthe StructuredText usage.  Although the Chicago Manual of Style says\nthat spaces should not be used around an em-dash, Peter Funk pointed\nout that this is standard usage in German (according to the Duden, the\nofficial German reference), and possibly in other languages as well.\nThe widespread use of ' -- ' precludes its use for definition lists;\nit would violate the \"unsurprising\" criterion.\n\nA simpler, and at least equally visually distinctive construct\n(proposed by Guido van Rossum, who incidentally is a frequent user of\n' -- ') would do just as well::\n\n    term 1\n        Definition.\n\n    term 2\n        Definition 2, paragraph 1.\n\n        Definition 2, paragraph 2.\n\nA reStructuredText definition list item consists of a term and a\ndefinition.  A term is a simple one-line paragraph.  A definition is a\nblock indented relative to the term, and may contain multiple\nparagraphs and other body elements.  No blank line precedes a\ndefinition (this distinguishes definition lists from block quotes).\n\n\nLiteral Blocks\n==============\n\nThe StructuredText_ specification has literal blocks indicated by\n'example', 'examples', or '::' ending the preceding paragraph.  STNG\nonly recognizes '::'; 'example'/'examples' are not implemented.  This\nis good; it fixes an unnecessary language dependency.  The problem is\nwhat to do with the sometimes- unwanted '::'.\n\nIn reStructuredText_ '::' at the end of a paragraph indicates that\nsubsequent *indented* blocks are treated as literal text.  No further\nmarkup interpretation is done within literal blocks (not even\nbackslash-escapes).  If the '::' is preceded by whitespace, '::' is\nomitted from the output; if '::' was the sole content of a paragraph,\nthe entire paragraph is removed (no 'empty' paragraph remains).  If\n'::' is preceded by a non-whitespace character, '::' is replaced by\n':' (i.e., the extra colon is removed).\n\nThus, a section could begin with a literal block as follows::\n\n    Section Title\n    -------------\n\n    ::\n\n        print \"this is example literal\"\n\n\nTables\n======\n\nThe table markup scheme in classic StructuredText was horrible.  Its\nomission from StructuredTextNG is welcome, and its markup will not be\nrepeated here.  However, tables themselves are useful in\ndocumentation.  Alternatives:\n\n1. This format is the most natural and obvious.  It was independently\n   invented (no great feat of creation!), and later found to be the\n   format supported by the `Emacs table mode`_::\n\n       +------------+------------+------------+--------------+\n       |  Header 1  |  Header 2  |  Header 3  |  Header 4    |\n       +============+============+============+==============+\n       |  Column 1  |  Column 2  | Column 3 & 4 span (Row 1) |\n       +------------+------------+------------+--------------+\n       |    Column 1 & 2 span    |  Column 3  | - Column 4   |\n       +------------+------------+------------+ - Row 2 & 3  |\n       |      1     |      2     |      3     | - span       |\n       +------------+------------+------------+--------------+\n\n   Tables are described with a visual outline made up of the\n   characters '-', '=', '|', and '+':\n\n   - The hyphen ('-') is used for horizontal lines (row separators).\n   - The equals sign ('=') is optionally used as a header separator\n     (as of version 1.5.24, this is not supported by the Emacs table\n     mode).\n   - The vertical bar ('|') is used for for vertical lines (column\n     separators).\n   - The plus sign ('+') is used for intersections of horizontal and\n     vertical lines.\n\n   Row and column spans are possible simply by omitting the column or\n   row separators, respectively.  The header row separator must be\n   complete; in other words, a header cell may not span into the table\n   body.  Each cell contains body elements, and may have multiple\n   paragraphs, lists, etc.  Initial spaces for a left margin are\n   allowed; the first line of text in a cell determines its left\n   margin.\n\n2. Below is a simpler table structure.  It may be better suited to\n   manual input than alternative #1, but there is no Emacs editing\n   mode available.  One disadvantage is that it resembles section\n   titles; a one-column table would look exactly like section &\n   subsection titles. ::\n\n       ============ ============ ============ ==============\n         Header 1     Header 2     Header 3     Header 4\n       ============ ============ ============ ==============\n         Column 1     Column 2    Column 3 & 4 span (Row 1)\n       ------------ ------------ ---------------------------\n           Column 1 & 2 span       Column 3    - Column 4\n       ------------------------- ------------  - Row 2 & 3\n             1            2            3       - span\n       ============ ============ ============ ==============\n\n   The table begins with a top border of equals signs with a space at\n   each column boundary (regardless of spans).  Each row is\n   underlined.  Internal row separators are underlines of '-', with\n   spaces at column boundaries.  The last of the optional head rows is\n   underlined with '=', again with spaces at column boundaries.\n   Column spans have no spaces in their underline.  Row spans simply\n   lack an underline at the row boundary.  The bottom boundary of the\n   table consists of '=' underlines.  A blank line is required\n   following a table.\n\n3. A minimalist alternative is as follows::\n\n       ====  =====  ========  ========  =======  ====  =====  =====\n       Old State    Input     Action             New State    Notes\n       -----------  --------  -----------------  -----------\n       ids   types  new type  sys.msg.  dupname  ids   types\n       ====  =====  ========  ========  =======  ====  =====  =====\n       --    --     explicit  --        --       new   True\n       --    --     implicit  --        --       new   False\n       None  False  explicit  --        --       new   True\n       old   False  explicit  implicit  old      new   True\n       None  True   explicit  explicit  new      None  True\n       old   True   explicit  explicit  new,old  None  True   [1]\n       None  False  implicit  implicit  new      None  False\n       old   False  implicit  implicit  new,old  None  False\n       None  True   implicit  implicit  new      None  True\n       old   True   implicit  implicit  new      old   True\n       ====  =====  ========  ========  =======  ====  =====  =====\n\n   The table begins with a top border of equals signs with one or more\n   spaces at each column boundary (regardless of spans).  There must\n   be at least two columns in the table (to differentiate it from\n   section headers).  Each line starts a new row.  The rightmost\n   column is unbounded; text may continue past the edge of the table.\n   Each row/line must contain spaces at column boundaries, except for\n   explicit column spans.  Underlines of '-' can be used to indicate\n   column spans, but should be used sparingly if at all.  Lines\n   containing column span underlines may not contain any other text.\n   The last of the optional head rows is underlined with '=', again\n   with spaces at column boundaries.  The bottom boundary of the table\n   consists of '=' underlines.  A blank line is required following a\n   table.\n\n   This table sums up the features.  Using all the features in such a\n   small space is not pretty though::\n\n       ========  ========  ========\n                 Header 2 & 3 Span\n                 ------------------\n       Header 1  Header 2  Header 3\n       ========  ========  ========\n       Each      line is   a new row.\n       Each row  consists  of one line only.\n       Row       spans     are not possible.\n       The last  column    may spill over to the right.\n       Column spans are possible with an underline joining columns.\n       ----------------------------\n       The span  is        limited to the row above the underline.\n       ========  ========  ========\n\n4. As a variation of alternative 3, bullet list syntax in the first\n   column could be used to indicate row starts.  Multi-line rows are\n   possible, but row spans are not.  For example::\n\n       ===== =====\n       col 1 col 2\n       ===== =====\n       - 1   Second column of row 1.\n       - 2   Second column of row 2.\n             Second line of paragraph.\n       - 3   Second column of row 3.\n\n             Second paragraph of row 3,\n             column 2\n       ===== =====\n\n   Column spans would be indicated on the line after the last line of\n   the row.  To indicate a real bullet list within a first-column\n   cell, simply nest the bullets.\n\n5. In a further variation, we could simply assume that whitespace in\n   the first column implies a multi-line row; the text in other\n   columns is continuation text.  For example::\n\n       ===== =====\n       col 1 col 2\n       ===== =====\n       1     Second column of row 1.\n       2     Second column of row 2.\n             Second line of paragraph.\n       3     Second column of row 3.\n\n             Second paragraph of row 3,\n             column 2\n       ===== =====\n\n   Limitations of this approach:\n\n   - Cells in the first column are limited to one line of text.\n\n   - Cells in the first column *must* contain some text; blank cells\n     would lead to a misinterpretation.  An empty comment (\"..\") is\n     sufficient.\n\n6. Combining alternative 3 and 4, a bullet list in the first column\n   could mean multi-line rows, and no bullet list means single-line\n   rows only.\n\nAlternatives 1 and 5 has been adopted by reStructuredText.\n\n\nDelimitation of Inline Markup\n=============================\n\nStructuredText specifies that inline markup must begin with\nwhitespace, precluding such constructs as parenthesized or quoted\nemphatic text::\n\n    \"**What?**\" she cried.  (*exit stage left*)\n\nThe `reStructuredText markup specification`_ allows for such\nconstructs and disambiguates inline markup through a set of\nrecognition rules.  These recognition rules define the context of\nmarkup start-strings and end-strings, allowing markup characters to be\nused in most non-markup contexts without a problem (or a backslash).\nSo we can say, \"Use asterisks (*) around words or phrases to\n*emphasisze* them.\" The '(*)' will not be recognized as markup.  This\nreduces the need for markup escaping to the point where an escape\ncharacter is *almost* (but not quite!) unnecessary.\n\n\nUnderlining\n===========\n\nStructuredText uses '_text_' to indicate underlining.  To quote David\nAscher in his 2000-01-21 Doc-SIG mailing list post, \"Docstring\ngrammar: a very revised proposal\":\n\n    The tagging of underlined text with _'s is suboptimal.  Underlines\n    shouldn't be used from a typographic perspective (underlines were\n    designed to be used in manuscripts to communicate to the\n    typesetter that the text should be italicized -- no well-typeset\n    book ever uses underlines), and conflict with double-underscored\n    Python variable names (__init__ and the like), which would get\n    truncated and underlined when that effect is not desired.  Note\n    that while *complete* markup would prevent that truncation\n    ('__init__'), I think of docstring markups much like I think of\n    type annotations -- they should be optional and above all do no\n    harm.  In this case the underline markup does harm.\n\nUnderlining is not part of the reStructuredText specification.\n\n\nInline Literals\n===============\n\nStructuredText's markup for inline literals (text left as-is,\nverbatim, usually in a monospaced font; as in HTML <TT>) is single\nquotes ('literals').  The problem with single quotes is that they are\ntoo often used for other purposes:\n\n- Apostrophes: \"Don't blame me, 'cause it ain't mine, it's Chris'.\";\n\n- Quoting text:\n\n      First Bruce: \"Well Bruce, I heard the prime minister use it.\n      'S'hot enough to boil a monkey's bum in 'ere your Majesty,' he\n      said, and she smiled quietly to herself.\"\n\n  In the UK, single quotes are used for dialogue in published works.\n\n- String literals: s = ''\n\nAlternatives::\n\n    'text'    \\'text\\'    ''text''    \"text\"    \\\"text\\\"    \"\"text\"\"\n    #text#     @text@      `text`     ^text^    ``text''    ``text``\n\nThe examples below contain inline literals, quoted text, and\napostrophes.  Each example should evaluate to the following HTML::\n\n    Some <TT>code</TT>, with a 'quote', \"double\", ain't it grand?\n    Does <TT>a[b] = 'c' + \"d\" + `2^3`</TT> work?\n\n    0. Some code, with a quote, double, ain't it grand?\n       Does a[b] = 'c' + \"d\" + `2^3` work?\n    1. Some 'code', with a \\'quote\\', \"double\", ain\\'t it grand?\n       Does 'a[b] = \\'c\\' + \"d\" + `2^3`' work?\n    2. Some \\'code\\', with a 'quote', \"double\", ain't it grand?\n       Does \\'a[b] = 'c' + \"d\" + `2^3`\\' work?\n    3. Some ''code'', with a 'quote', \"double\", ain't it grand?\n       Does ''a[b] = 'c' + \"d\" + `2^3`'' work?\n    4. Some \"code\", with a 'quote', \\\"double\\\", ain't it grand?\n       Does \"a[b] = 'c' + \"d\" + `2^3`\" work?\n    5. Some \\\"code\\\", with a 'quote', \"double\", ain't it grand?\n       Does \\\"a[b] = 'c' + \"d\" + `2^3`\\\" work?\n    6. Some \"\"code\"\", with a 'quote', \"double\", ain't it grand?\n       Does \"\"a[b] = 'c' + \"d\" + `2^3`\"\" work?\n    7. Some #code#, with a 'quote', \"double\", ain't it grand?\n       Does #a[b] = 'c' + \"d\" + `2^3`# work?\n    8. Some @code@, with a 'quote', \"double\", ain't it grand?\n       Does @a[b] = 'c' + \"d\" + `2^3`@ work?\n    9. Some `code`, with a 'quote', \"double\", ain't it grand?\n       Does `a[b] = 'c' + \"d\" + \\`2^3\\`` work?\n    10. Some ^code^, with a 'quote', \"double\", ain't it grand?\n        Does ^a[b] = 'c' + \"d\" + `2\\^3`^ work?\n    11. Some ``code'', with a 'quote', \"double\", ain't it grand?\n        Does ``a[b] = 'c' + \"d\" + `2^3`'' work?\n    12. Some ``code``, with a 'quote', \"double\", ain't it grand?\n        Does ``a[b] = 'c' + \"d\" + `2^3\\``` work?\n\nBackquotes (#9 & #12) are the best choice.  They are unobtrusive and\nrelatviely rarely used (more rarely than ' or \", anyhow).  Backquotes\nhave the connotation of 'quotes', which other options (like carets,\n#10) don't.\n\nAnalogously with ``*emph*`` & ``**strong**``, double-backquotes (#12)\ncould be used for inline literals.  If single-backquotes are used for\n'interpreted text' (context-sensitive domain-specific descriptive\nmarkup) such as function name hyperlinks in Python docstrings, then\ndouble-backquotes could be used for absolute-literals, wherein no\nprocessing whatsoever takes place.  An advantage of double-backquotes\nwould be that backslash-escaping would no longer be necessary for\nembedded single-backquotes; however, embedded double-backquotes (in an\nend-string context) would be illegal.  See `Backquotes in\nPhrase-Links`__ in `Record of reStructuredText Syntax Alternatives`__.\n\n__ alternatives.html#backquotes-in-phrase-links\n__ alternatives.html\n\nAlternative choices are carets (#10) and TeX-style quotes (#11).  For\nexamples of TeX-style quoting, see\nhttp://www.zope.org/Members/jim/StructuredTextWiki/CustomizingTheDocumentProcessor.\n\nSome existing uses of backquotes:\n\n1. As a synonym for repr() in Python.\n2. For command-interpolation in shell scripts.\n3. Used as open-quotes in TeX code (and carried over into plaintext\n   by TeXies).\n\nThe inline markup start-string and end-string recognition rules\ndefined by the `reStructuredText markup specification`_ would allow\nall of these cases inside inline literals, with very few exceptions.\nAs a fallback, literal blocks could handle all cases.\n\nOutside of inline literals, the above uses of backquotes would require\nbackslash-escaping.  However, these are all prime examples of text\nthat should be marked up with inline literals.\n\nIf either backquotes or straight single-quotes are used as markup,\nTeX-quotes are too troublesome to support, so no special-casing of\nTeX-quotes should be done (at least at first).  If TeX-quotes have to\nbe used outside of literals, a single backslash-escaped would suffice:\n\\``TeX quote''.  Ugly, true, but very infrequently used.\n\nUsing literal blocks is a fallback option which removes the need for\nbackslash-escaping::\n\n    like this::\n\n        Here, we can do ``absolutely'' anything `'`'\\|/|\\ we like!\n\nNo mechanism for inline literals is perfect, just as no escaping\nmechanism is perfect.  No matter what we use, complicated inline\nexpressions involving the inline literal quote and/or the backslash\nwill end up looking ugly.  We can only choose the least often ugly\noption.\n\nreStructuredText will use double backquotes for inline literals, and\nsingle backqoutes for interpreted text.\n\n\nHyperlinks\n==========\n\nThere are three forms of hyperlink currently in StructuredText_:\n\n1. (Absolute & relative URIs.)  Text enclosed by double quotes\n   followed by a colon, a URI, and concluded by punctuation plus white\n   space, or just white space, is treated as a hyperlink::\n\n       \"Python\":http://www.python.org/\n\n2. (Absolute URIs only.)  Text enclosed by double quotes followed by a\n   comma, one or more spaces, an absolute URI and concluded by\n   punctuation plus white space, or just white space, is treated as a\n   hyperlink::\n\n       \"mail me\", mailto:me@mail.com\n\n3. (Endnotes.)  Text enclosed by brackets link to an endnote at the\n   end of the document: at the beginning of the line, two dots, a\n   space, and the same text in brackets, followed by the end note\n   itself::\n\n       Please refer to the fine manual [GVR2001].\n\n       .. [GVR2001] Python Documentation, Release 2.1, van Rossum,\n          Drake, et al., http://www.python.org/doc/\n\nThe problem with forms 1 and 2 is that they are neither intuitive nor\nunobtrusive (they break design goals 5 & 2).  They overload\ndouble-quotes, which are too often used in ordinary text (potentially\nbreaking design goal 4).  The brackets in form 3 are also too common\nin ordinary text (such as [nested] asides and Python lists like [12]).\n\nAlternatives:\n\n1. Have no special markup for hyperlinks.\n\n2. A. Interpret and mark up hyperlinks as any contiguous text\n      containing '://' or ':...@' (absolute URI) or '@' (email\n      address) after an alphanumeric word.  To de-emphasize the URI,\n      simply enclose it in parentheses:\n\n          Python (http://www.python.org/)\n\n   B. Leave special hyperlink markup as a domain-specific extension.\n      Hyperlinks in ordinary reStructuredText documents would be\n      required to be standalone (i.e. the URI text inline in the\n      document text).  Processed hyperlinks (where the URI text is\n      hidden behind the link) are important enough to warrant syntax.\n\n3. The original Setext_ introduced a mechanism of indirect hyperlinks.\n   A source link word ('hot word') in the text was given a trailing\n   underscore::\n\n       Here is some text with a hyperlink_ built in.\n\n   The hyperlink itself appeared at the end of the document on a line\n   by itself, beginning with two dots, a space, the link word with a\n   leading underscore, whitespace, and the URI itself::\n\n       .. _hyperlink http://www.123.xyz\n\n   Setext used ``underscores_instead_of_spaces_`` for phrase links.\n\nWith some modification, alternative 3 best satisfies the design goals.\nIt has the advantage of being readable and relatively unobtrusive.\nSince each source link must match up to a target, the odd variable\nending in an underscore can be spared being marked up (although it\nshould generate a \"no such link target\" warning).  The only\ndisadvantage is that phrase-links aren't possible without some\nobtrusive syntax.\n\nWe could achieve phrase-links if we enclose the link text:\n\n1. in double quotes::\n\n       \"like this\"_\n\n2. in brackets::\n\n       [like this]_\n\n3. or in backquotes::\n\n       `like this`_\n\nEach gives us somewhat obtrusive markup, but that is unavoidable.  The\nbracketed syntax (#2) is reminiscent of links on many web pages\n(intuitive), although it is somewhat obtrusive.  Alternative #3 is\nmuch less obtrusive, and is consistent with interpreted text: the\ntrailing underscore indicates the interpretation of the phrase, as a\nhyperlink.  #3 also disambiguates hyperlinks from footnote references.\nAlternative #3 wins.\n\nThe same trailing underscore markup can also be used for footnote and\ncitation references, removing the problem with ordinary bracketed text\nand Python lists::\n\n    Please refer to the fine manual [GVR2000]_.\n\n    .. [GVR2000] Python Documentation, van Rossum, Drake, et al.,\n       http://www.python.org/doc/\n\nThe two-dots-and-a-space syntax was generalized by Setext for\ncomments, which are removed from the (visible) processed output.\nreStructuredText uses this syntax for comments, footnotes, and link\ntarget, collectively termed \"explicit markup\".  For link targets, in\norder to eliminate ambiguity with comments and footnotes,\nreStructuredText specifies that a colon always follow the link target\nword/phrase.  The colon denotes 'maps to'.  There is no reason to\nrestrict target links to the end of the document; they could just as\neasily be interspersed.\n\nInternal hyperlinks (links from one point to another within a single\ndocument) can be expressed by a source link as before, and a target\nlink with a colon but no URI.  In effect, these targets 'map to' the\nelement immediately following.\n\nAs an added bonus, we now have a perfect candidate for\nreStructuredText directives, a simple extension mechanism: explicit\nmarkup containing a single word followed by two colons and whitespace.\nThe interpretation of subsequent data on the directive line or\nfollowing is directive-dependent.\n\nTo summarize::\n\n    .. This is a comment.\n\n    .. The line below is an example of a directive.\n    .. version:: 1\n\n    This is a footnote [1]_.\n\n    This internal hyperlink will take us to the footnotes_ area below.\n\n    Here is a one-word_ external hyperlink.\n\n    Here is `a hyperlink phrase`_.\n\n    .. _footnotes:\n    .. [1] Footnote text goes here.\n\n    .. external hyperlink target mappings:\n    .. _one-word: http://www.123.xyz\n    .. _a hyperlink phrase: http://www.123.xyz\n\nThe presence or absence of a colon after the target link\ndifferentiates an indirect hyperlink from a footnote, respectively.  A\nfootnote requires brackets.  Backquotes around a target link word or\nphrase are required if the phrase contains a colon, optional\notherwise.\n\nBelow are examples using no markup, the two StructuredText hypertext\nstyles, and the reStructuredText hypertext style.  Each example\ncontains an indirect link, a direct link, a footnote/endnote, and\nbracketed text.  In HTML, each example should evaluate to::\n\n    <P>A <A HREF=\"http://spam.org\">URI</A>, see <A HREF=\"#eggs2000\">\n    [eggs2000]</A> (in Bacon [Publisher]).  Also see\n    <A HREF=\"http://eggs.org\">http://eggs.org</A>.</P>\n\n    <P><A NAME=\"eggs2000\">[eggs2000]</A> \"Spam, Spam, Spam, Eggs,\n    Bacon, and Spam\"</P>\n\n1. No markup::\n\n       A URI http://spam.org, see eggs2000 (in Bacon [Publisher]).\n       Also see http://eggs.org.\n\n       eggs2000 \"Spam, Spam, Spam, Eggs, Bacon, and Spam\"\n\n2. StructuredText absolute/relative URI syntax\n   (\"text\":http://www.url.org)::\n\n       A \"URI\":http://spam.org, see [eggs2000] (in Bacon [Publisher]).\n       Also see \"http://eggs.org\":http://eggs.org.\n\n       .. [eggs2000] \"Spam, Spam, Spam, Eggs, Bacon, and Spam\"\n\n   Note that StructuredText does not recognize standalone URIs,\n   forcing doubling up as shown in the second line of the example\n   above.\n\n3. StructuredText absolute-only URI syntax\n   (\"text\", mailto:you@your.com)::\n\n       A \"URI\", http://spam.org, see [eggs2000] (in Bacon\n       [Publisher]).  Also see \"http://eggs.org\", http://eggs.org.\n\n       .. [eggs2000] \"Spam, Spam, Spam, Eggs, Bacon, and Spam\"\n\n4. reStructuredText syntax::\n\n    4. A URI_, see [eggs2000]_ (in Bacon [Publisher]).\n       Also see http://eggs.org.\n\n       .. _URI: http:/spam.org\n       .. [eggs2000] \"Spam, Spam, Spam, Eggs, Bacon, and Spam\"\n\nThe bracketed text '[Publisher]' may be problematic with\nStructuredText (syntax 2 & 3).\n\nreStructuredText's syntax (#4) is definitely the most readable.  The\ntext is separated from the link URI and the footnote, resulting in\ncleanly readable text.\n\n.. _StructuredText: https://zopestructuredtext.readthedocs.org/\n.. _Setext: https://docutils.sourceforge.io/mirror/setext.html\n.. _reStructuredText: https://docutils.sourceforge.io/rst.html\n.. _detailed description:\n   http://homepage.ntlworld.com/tibsnjoan/docutils/STNG-format.html\n.. _STMinus: http://www.cis.upenn.edu/~edloper/pydoc/stminus.html\n.. _StructuredTextNG:\n   http://www.zope.org/DevHome/Members/jim/StructuredTextWiki/StructuredTextNG\n.. _README: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/~checkout~/\n   python/python/dist/src/README\n.. _Emacs table mode: http://table.sourceforge.net/\n.. _reStructuredText Markup Specification:\n   ../../ref/rst/restructuredtext.html\n\n\f\n..\n   Local Variables:\n   mode: indented-text\n   indent-tabs-mode: nil\n   sentence-end-double-space: t\n   fill-column: 70\n   End:\n"

    "content": "=============================\n Runtime Settings Processing\n=============================\n\n:Author: David Goodger, Günter Milde\n:Contact: docutils-develop@lists.sourceforge.net\n:Date: $Date$\n:Revision: $Revision$\n:Copyright: This document has been placed in the public domain.\n\n:Abstract: A detailled description of Docutil's settings processing\n           framework.\n\n.. contents::\n\n\nThe ``docutils/__init__.py``, ``docutils/core.py``, and\n``docutils.frontend.py`` modules are described.\nFollowing along with the actual code is recommended.\n\nSee `Docutils Runtime Settings`_ for a high-level description of the core\nAPI and `Docutils Configuration`_ for a description of the individual\nsettings.\n\n.. note::\n   This document is informal.\n   It describes the state in Docutils 0.18.1.\n   Implementation details will change with the move to replace the\n   deprecated optparse_ module with argparse_.\n\n\nSettings priority\n=================\n\nDocutils overlays default and explicitly specified values from various\nsources such that settings behave the way we want and expect them to\nbehave.\n\nThe souces are overlaid in the following order (later sources\noverwrite earlier ones):\n\n1. Defaults specified in `settings_spec`__ and\n   `settings_defaults`__ attributes for each component_.\n   (details__)\n\n   __ ../api/runtime-settings.html#settingsspec-settings-spec\n   __ ../api/runtime-settings.html#settingsspec-settings-defaults\n   __ `OptionParser.populate_from_components()`_\n\n2. Defaults specified in `settings_default_overrides`__ attribute for\n   each component_.\n   (details__)\n\n   __ ../api/runtime-settings.html#settingsspec-settings-default-overrides\n   __ component.settings_default_overrides_\n\n3. Settings specified in the `settings_overrides parameter`_ of the\n   `convenience functions`_ rsp. the `settings_overrides` attribute of\n   a `core.Publisher` instance.\n   (details__)\n\n   __ OptionParser.defaults_\n\n4. If enabled, settings specified in `active sections`_ of the\n   `configuration files`_ in the order described in\n   `Configuration File Sections & Entries`_. (details__)\n\n   See also `Configuration File Sections & Entries`_.\n\n   __ `OptionParser.get_standard_config_settings()`_\n\n5. If enabled, command line arguments (details__).\n\n   __ `Publisher.process_command_line()`_\n\n\nSettings assigned to the `settings parameter`_ of the\n`convenience functions`_ or the ``Publisher.settings`` attribute\nare used **instead of** the above sources\n(see below for details for `command-line tools`__ and\n`other applications`__).\n\n__ `publisher.publish()`_\n__ `publisher.process_programmatic_settings()`_\n\n.. _command-line tools:\n\nRuntime settings processing for command-line tools\n==================================================\n\nThe command-line `front-end tools`_ usually import and call\nthe `convenience function`_ ``docutils.core.publish_cmdline()``.\n\n1. ``docutils.core.publish_cmdline()`` creates a `Publisher`_ instance::\n\n       publisher = core.Publisher(…, settings)\n\n   eventually sets the components_ from the respective names, and calls ::\n\n       publisher.publish(argv, …, settings_spec,\n                         settings_overrides, config_section, …)\n\n   .. _publisher.publish():\n\n2. If `publisher.settings` is None, ``publisher.publish()`` calls::\n\n       publisher.process_command_line(…,\n           settings_spec, config_section, **defaults)\n\n   with `defaults` taken from `publisher.settings_overrides`.\n\n   If `publisher.settings` is defined, steps 3 to 5 are skipped.\n\n3. ``publisher.process_command_line()`` calls::\n\n       optpar = publisher.setup_option_parser(…,\n                    settings_spec, config_section, **defaults)\n\n   .. _publisher.setup_option_parser():\n\n4. ``publisher.setup_option_parser()``\n\n   - merges the value of the `config_section parameter`_ into\n     `settings_spec` and\n\n   - creates an `OptionParser` instance ::\n\n        optpar = docutils.frontend.OptionParser(components, defaults)\n\n     with `components` the tuple of the `SettingsSpec`_ instances\n     ``(publisher.parser, publisher.reader, publisher.writer, settings_spec)``\n\n   .. _OptionParser.populate_from_components():\n\n5. The `OptionParser` instance prepends itself to the `components` tuple\n   and calls ``self.populate_from_components(components)``, which updates\n   the attribute ``self.defaults`` in two steps:\n\n   a) For each component passed, ``component.settings_spec`` is processed\n      and ``component.settings_defaults`` is applied.\n\n      .. _component.settings_default_overrides:\n\n   b) In a second loop, for each component\n      ``component.settings_default_overrides`` is applied. This way,\n      ``component.settings_default_overrides`` can override the default\n      settings of any other component.\n\n   .. _OptionParser.defaults:\n\n6. Back in ``OptionParser.__init__()``, ``self.defaults`` is updated with\n   the `defaults` argument passed to ``OptionParser(…)`` in step 5.\n\n   This means that the `settings_overrides` argument of the\n   `convenience functions`_ has priority over all\n   ``SettingsSpec.settings_spec`` defaults.\n\n   .. _OptionParser.get_standard_config_settings():\n\n7. If configuration files are enabled,\n   ``self.get_standard_config_settings()`` is called.\n\n   This reads the Docutils `configuration files`_, and returns a\n   dictionary of settings in `active sections`_ which is used to update\n   ``optpar.defaults``. So configuration file settings have priority over\n   all software-defined defaults.\n\n   .. _Publisher.process_command_line():\n\n8. ``publisher.process_command_line()`` calls ``optpar.parse_args()``.\n   The OptionParser parses all command line options and returns a\n   `docutils.frontend.Values` object.\n   This is assigned to ``publisher.settings``.\n   So command-line options have priority over configuration file\n   settings.\n\n9. The `<source>` and `<destination>` command-line arguments\n   are also parsed, and assigned to ``publisher.settings._source``\n   and ``publisher.settings._destination`` respectively.\n\n10. ``publisher.publish()`` calls ``publisher.set_io()`` with no arguments.\n    If either ``publisher.source`` or ``publisher.destination`` are not\n    set, the corresponding ``publisher.set_source()`` and\n    ``publisher.set_destination()`` are called:\n\n    ``publisher.set_source()``\n      checks for a ``source_path`` argument, and if there is none (which\n      is the case for command-line use), it is taken from\n      ``publisher.settings._source``.  ``publisher.source`` is set by\n      instantiating a ``publisher.source_class`` object.\n      For command-line front-end tools, the default\n      ``publisher.source_class`` (i.e. ``docutils.io.FileInput``)\n      is used.\n\n    ``publisher.set_destination()``\n      does the same job for the destination. (the default\n      ``publisher.destination_class`` is ``docutils.io.FileOutput``).\n\n    .. _accessing the runtime settings:\n\n11. ``publisher.publish()`` passes ``publisher.settings`` to the reader_\n    component's ``read()`` method.\n\n12. The reader component creates a new `document root node`__.\n    ``nodes.document.__init__()`` adds the settings to the internal\n    attributes.\n\n    __ ../ref/doctree.html#document\n\n    All components acting on the Document Tree are handed the\n    ``document`` root node and can access the runtime settings as\n    ``document.settings``.\n\n\nRuntime settings processing for other applications\n==================================================\n\nThe `convenience functions`_ , ``core.publish_file()``,\n``core.publish_string()``, or ``core.publish_parts()`` do not parse the\ncommand line for settings.\n\n1. The convenience functions call the generic programmatic interface\n   function ``core.publish_programmatically()`` that creates a\n   `core.Publisher` instance ::\n\n       pub = core.Publisher(…, settings)\n\n   eventually sets the components_ from the respective names, and calls ::\n\n       publisher.process_programmatic_settings(\n           settings_spec, settings_overrides, config_section)\n\n   .. _publisher.process_programmatic_settings():\n\n2. If `publisher.settings` is None,\n   ``publisher.process_programmatic_settings()`` calls::\n\n       publisher.get_settings(settings_spec, config_section, **defaults)\n\n   with `defaults` taken from `publisher.settings_overrides`.\n\n   If `publisher.settings` is defined, the following steps are skipped.\n\n3. ``publisher.get_settings()`` calls::\n\n       optpar = publisher.setup_option_parser(…,\n                    settings_spec, config_section, **defaults)\n\n4. The OptionParser instance determines setting defaults\n   as described in `steps 4 to 7`__ in the previous section.\n\n   __ `publisher.setup_option_parser()`_\n\n5. Back in ``publisher.get_settings()``, the ``frontend.Values`` instance\n   returned by ``optpar.get_default_values()`` is stored in\n   ``publisher.settings``.\n\n6. ``publish_programmatically()`` continues with setting\n   ``publisher.source`` and ``publisher.destination``.\n\n7. Finally, ``publisher.publish()`` is called. As ``publisher.settings``\n   is not None, no further command line processing takes place.\n\n8. All components acting on the Document Tree are handed the\n   ``document`` root node and can access the runtime settings as\n   ``document.settings`` (cf. `steps 11 and 12`__ in the previous section).\n\n   __ `accessing the runtime settings`_\n\n\n..

    "content": "=====================\n Docstring Semantics\n=====================\n:Author: David Goodger\n:Contact: docutils-develop@lists.sourceforge.net\n:Revision: $Revision$\n:Date: $Date$\n:Copyright: This document has been placed in the public domain.\n\nThese are notes for a possible future PEP providing the final piece of\nthe Python docstring puzzle: docstring semantics or documentation\nmethodology.  `PEP 257`_, Docstring Conventions, sketches out some\nguidelines, but does not get into methodology details.\n\nI haven't explored documentation methodology more because, in my\nopinion, it is a completely separate issue from syntax, and it's even\nmore controversial than syntax.  Nobody wants to be told how to lay\nout their documentation, a la JavaDoc_.  I think the JavaDoc way is\nbutt-ugly, but it *is* an established standard for the Java world.\nAny standard documentation methodology has to be formal enough to be\nuseful but remain light enough to be usable.  If the methodology is\ntoo strict, too heavy, or too ugly, many/most will not want to use it.\n\nI think a standard methodology could benefit the Python community, but\nit would be a hard sell.  A PEP would be the place to start.  For most\nhuman-readable documentation needs, the free-form text approach is\nadequate.  We'd only need a formal methodology if we want to extract\nthe parameters into a data dictionary, index, or summary of some kind.\n\n\nPythonDoc\n=========\n\n(Not to be confused with Daniel Larsson's pythondoc_ project.)\n\nA Python version of the JavaDoc_ semantics (not syntax).  A set of\nconventions which are understood by the Docutils.  What JavaDoc has\ndone is to establish a syntax that enables a certain documentation\nmethodology, or standard *semantics*.  JavaDoc is not just syntax; it\nprescribes a methodology.\n\n- Use field lists or definition lists for \"tagged blocks\".  By this I\n  mean that field lists can be used similarly to JavaDoc's ``@tag``\n  syntax.  That's actually one of the motivators behind field lists.\n  For example, we could have::\n\n      \"\"\"\n      :Parameters:\n          - `lines`: a list of one-line strings without newlines.\n          - `until_blank`: Stop collecting at the first blank line if\n            true (1).\n          - `strip_indent`: Strip common leading indent if true (1,\n            default).\n\n      :Return:\n          - a list of indented lines with minimum indent removed;\n          - the amount of the indent;\n          - whether or not the block finished with a blank line or at\n            the end of `lines`.\n      \"\"\"\n\n  This is taken straight out of docutils/statemachine.py, in which I\n  experimented with a simple documentation methodology.  Another\n  variation I've thought of exploits the Grouch_-compatible\n  \"classifier\" element of definition lists.  For example::\n\n      :Parameters:\n          `lines` : [string]\n              List of one-line strings without newlines.\n          `until_blank` : boolean\n              Stop collecting at the first blank line if true (1).\n          `strip_indent` : boolean\n              Strip common leading indent if true (1, default).\n\n- Field lists could even be used in a one-to-one correspondence with\n  JavaDoc ``@tags``, although I doubt if I'd recommend it.  Several\n  ports of JavaDoc's ``@tag`` methodology exist in Python, most\n  recently Ed Loper's \"epydoc_\".\n\n\nOther Ideas\n===========\n\n- Can we extract comments from parsed modules?  Could be handy for\n  documenting function/method parameters::\n\n      def method(self,\n                 source,        # path of input file\n                 dest           # path of output file\n                ):\n\n  This would save having to repeat parameter names in the docstring.\n\n  Idea from Mark Hammond's 1998-06-23 Doc-SIG post, \"Re: [Doc-SIG]\n  Documentation tool\":\n\n      it would be quite hard to add a new param to this method without\n      realising you should document it\n\n- Frederic Giacometti's `iPhrase Python documentation conventions`_ is\n  an attachment to his Doc-SIG post of 2001-05-30.\n\n\n.. _PEP 257: https://peps.python.org/pep-0257\n.. _JavaDoc: http://java.sun.com/j2se/javadoc/\n.. _pythondoc: http://starship.python.net/crew/danilo/pythondoc/\n.. _Grouch: http://www.mems-exchange.org/software/grouch/\n.. _epydoc: http://epydoc.sourceforge.net/\n.. _iPhrase Python documentation conventions:\n   https://mail.python.org/pipermail/doc-sig/2001-May/001840.html\n\n\f\n..\n   Local Variables:\n   mode: indented-text\n   indent-tabs-mode: nil\n   sentence-end-double-space: t\n   fill-column: 70\n   End:\n"

Practise test-first programming; it's fun,\nit's addictive, and it works!\n\nThis document describes how to run the Docutils test suite, how the\ntests are organized and how to add new tests or modify existing tests.\n\n\nRunning the Test Suite\n======================\n\nBefore checking in any changes, run the entire Docutils test suite to\nbe sure that you haven't broken anything.  From a shell do [#]_::\n\n    cd docutils/test\n    python -u alltests.py\n\nBefore `checking in`__ changes to the Docutils core, run the tests on\nall `supported Python versions`_ (see below for details).\nIn a pinch, the edge cases should cover most of it.\n\n__ policies.html#check-ins\n\n.. note::\n   Due to incompatible customization of the standard unittest_\n   framework, the test suite does not work with popular test frameworks\n   like pytest_ or nose_.\n\n   .. _unittest: https://docs.python.org/3/library/unittest.html\n   .. _pytest: https://pypi.org/project/pytest/\n   .. _nose: https://pypi.org/project/nose3/\n\n   .. cf. https://sourceforge.net/p/docutils/feature-requests/81/\n\n.. [#] When using the `Python launcher for Windows`__, make sure to\n   specify a Python version, e.g., ``py -3.9 -u alltests.py`` for\n   Python 3.9.\n\n   __ https://docs.python.org/3/using/windows.html#python-launcher-for-windows\n\n   .. cf. https://sourceforge.net/p/docutils/bugs/434/\n\n\n.. _Python versions:\n\nTesting across multiple Python versions\n---------------------------------------\n\nA Docutils release has a commitment to support a minimum Python version [#]_\nand beyond. Before a release is cut, tests must pass in all\n`supported versions`_.\n\nYou can use `tox`_ to test with all supported versions in one go.\nFrom the shell::\n\n    cd docutils\n    tox\n\nTo test a specific version, use the ``pyNN`` environment. For example::\n\n    tox -e py37\n\n`pyenv`_ can be installed and configured (see `installing pyenv`_) to\nget multiple Python versions::\n\n    # assuming your system runs 3.9.x\n    pyenv install 3.7.12\n    pyenv install 3.8.12\n    pyenv install 3.10.1\n    pyenv global system 3.7.12 3.8.12 3.10.1\n\n    # reset your shims\n    rm -rf ~/.pyenv/shims && pyenv rehash\n\nThis will give you ``python3.7`` through ``python3.10``.\nThen run::\n\n    python3.7 -u alltests.py\n    [...]\n    python3.10 -u alltests.py\n\n.. [#] Good resources covering the differences between Python versions\n   are the `What's New` documents (`What's New in Python 3.10`__ and\n   similar).\n\n__ https://docs.python.org/3/whatsnew/3.10.html\n\n\n.. _supported versions:\n.. _supported Python versions: ../../README.html#requirements\n.. _pyenv: https://github.com/yyuu/pyenv\n.. _installing pyenv: https://github.com/yyuu/pyenv#installation\n.. _tox: https://pypi.org/project/tox/\n\n\nUnit Tests\n==========\n\nUnit tests test single functions or modules (i.e. whitebox testing).\n\nIf you are implementing a new feature, be sure to write a test case\ncovering its functionality.  It happens very frequently that your\nimplementation (or even only a part of it) doesn't work with an older\n(or even newer) Python version, and the only reliable way to detect\nthose cases is using tests.\n\nOften, it's easier to write the test first and then implement the\nfunctionality required to make the test pass.\n\n\nWriting New Tests\n-----------------\n\nWhen writing new tests, it very often helps to see how a similar test\nis implemented.  For example, the files in the\n``test_parsers/test_rst/`` directory all look very similar.  So when\nadding a test, you don't have to reinvent the wheel.\n\nIf there is no similar test, you can write a new test from scratch\nusing Python's ``unittest`` module.  For an example, please have a\nlook at the following imaginary ``test_square.py``::\n\n    #! /usr/bin/env python\n\n    # $Id$\n    # Author: Your Name <your_email_address@example.org>\n    # Copyright: This module has been placed in the public domain.\n\n    \"\"\"\n    Test module for docutils.square.\n    \"\"\"\n\n    import unittest\n    import docutils.square\n\n\n    class SquareTest(unittest.TestCase):\n\n        def test_square(self):\n            self.assertEqual(docutils.square.square(0), 0)\n            self.assertEqual(docutils.square.square(5), 25)\n            self.assertEqual(docutils.square.square(7), 49)\n\n        def test_square_root(self):\n            self.assertEqual(docutils.square.sqrt(49), 7)\n            self.assertEqual(docutils.square.sqrt(0), 0)\n            self.assertRaises(docutils.square.SquareRootError,\n                              docutils.square.sqrt, 20)\n\n\n    if __name__ == '__main__':\n        unittest.main()\n\nFor more details on how to write tests, please refer to the\ndocumentation of the ``unittest`` module.\n\n.. Note::\n\n   Unit tests and functional test should generally set ::\n\n     settings_overrides['_disable_config'] = True\n\n   in order to be independent on the users local configuration.\n\n.. _functional:\n\nFunctional Tests\n================\n\nThe directory ``test/functional/`` contains data for functional tests.\n\nPerforming functional testing means testing the Docutils system as a\nwhole (i.e. blackbox testing).\n\n\nDirectory Structure\n-------------------\n\n+ ``functional/`` The main data directory.\n\n  + ``input/`` The input files.\n\n    - ``some_test.txt``, for example.\n\n  + ``output/`` The actual output.\n\n    - ``some_test.html``, for example.\n\n  + ``expected/`` The expected output.\n\n    - ``some_test.html``, for example.\n\n  + ``tests/`` The config files for processing the input files.\n\n    - ``some_test.py``, for example.\n\n    - ``_default.py``, the `default configuration file`_.\n\n\nThe Testing Process\n-------------------\n\nWhen running ``test_functional.py``, all config files in\n``functional/tests/`` are processed.  (Config files whose names begin\nwith an underscore are ignored.)  The current working directory is\nalways Docutils' main test directory (``test/``).\n\nFor example, ``functional/tests/some_test.py`` could read like this::\n\n    # Source and destination file names.\n    test_source = \"some_test.txt\"\n    test_destination = \"some_test.html\"\n\n    # Keyword parameters passed to publish_file.\n    reader_name = \"standalone\"\n    parser_name = \"rst\"\n    writer_name = \"html\"\n    settings_overrides['output-encoding'] = 'utf-8'\n    # Relative to main ``test/`` directory.\n    settings_overrides['stylesheet_path'] = '../docutils/writers/html4css1/html4css1.css'\n\nThe two variables ``test_source`` and ``test_destination`` contain the\ninput file name (relative to ``functional/input/``) and the output\nfile name (relative to ``functional/output/`` and\n``functional/expected/``).  Note that the file names can be chosen\narbitrarily.  However, the file names in ``functional/output/`` *must*\nmatch the file names in ``functional/expected/``.\n\nIf defined, ``_test_more`` must be a function with the following\nsignature::\n\n    def _test_more(expected_dir, output_dir, test_case, parameters):\n\nThis function is called from the test case to perform tests beyond the\nsimple comparison of expected and actual output files.\n\n``test_source`` and ``test_destination`` are removed from the\nnamespace, as are all variables whose names begin with an underscore\n(\"_\").  The remaining names are passed as keyword arguments to\n``docutils.core.publish_file``, so you can set reader, parser, writer\nand anything else you want to configure.  Note that\n``settings_overrides`` is already initialized as a dictionary *before*\nthe execution of the config file.\n\n\nCreating New Tests\n------------------\n\nIn order to create a new test, put the input test file into\n``functional/input/``.  Then create a config file in\n``functional/tests/`` which sets at least input and output file names,\nreader, parser and writer.\n\nNow run ``test_functional.py``.  The test will fail, of course,\nbecause you do not have an expected output yet.  However, an output\nfile will have been generated in ``functional/output/``.  Check this\noutput file for validity [#]_ and correctness.  Then copy the file to\n``functional/expected/``.\n\nIf you rerun ``test_functional.py`` now, it should pass.\n\nIf you run ``test_functional.py`` later and the actual output doesn't\nmatch the expected output anymore, the test will fail.\n\nIf this is the case and you made an intentional change, check the\nactual output for validity and correctness, copy it to\n``functional/expected/`` (overwriting the old expected output), and\ncommit the change.\n\n.. [#] The validity of `Docutils XML` can be tested with\n   ``xmllint <document-referencing-local-Docutils-DTD>.xml --valid --noout``.\n\n   .. note: the ``--dtdvalid`` and ``--nonet`` options did not help override\n     a reference to the PUBLIC \"docutils.dtd\" if there is a local version\n     on the system (e.g. /usr/share/xml/docutils/docutils.dtd in Debian).\n\n\n.. _default configuration file:\n\nThe Default Configuration File\n------------------------------\n\nThe file ``functional/tests/_default.py`` contains default settings.\nIt is executed just before the actual configuration files, which has\nthe same effect as if the contents of ``_default.py`` were prepended\nto every configuration file.\n"

So all the SVN history, all branches, and the full sandbox\n    need to be converted at the same time.\n\n  __ https://sourceforge.net/p/docutils/mailman/message/31878077/\n\nConvert with reposurgeon_?\n\n  If you are doing a full import rather than gatewaying, reposurgeon is\n  probably what you want. It has been tested against a lot of large, old,\n  nasty repositories and is thus known to be robust in the presence of\n  repository malformations (a property regularly checked by a test suite\n  that is a rogue's gallery of Subversion botches).\n\n  -- `Git Wiki`__\n\nThe comprehensive `Reposurgeon documentation`_ comes with\n`a guide to repository conversion`__\nas well as info about `reading Subversion repositories`__.\nConverting from an SVN dump file is faster than from a checkout.\n\n.. _reposurgeon: http://www.catb.org/esr/reposurgeon/\n.. _reposurgeon documentation:\n    http://www.catb.org/esr/reposurgeon/repository-editing.html\n__ https://git.wiki.kernel.org/index.php/\n   Interfaces,_frontends,_and_tools#Subversion\n__ http://www.catb.org/esr/reposurgeon/repository-editing.html#conversion   \n__ http://www.catb.org/esr/reposurgeon/repository-editing.html\n   #_reading_subversion_repositories   \n\n\nAdam Turner wrote a conversion Makefile and ``.lift`` scripts that\ndownloads the repo from SF with rsync, converts it to a SVN mirror and\nfinally to Git, splitting sandbox, prest, and web from docutils.\n\n\nSourceforge supports multiple Git repositories per project, so we can\nswitch the version control system independent of the decision on an\neventual switch of the host.\nCf. https://sourceforge.net/p/forge/documentation/Git/\n\n\nGeneral\n=======\n\nMiscellaneous\n-------------\n\nCode cleanup and modernization:\n  Use flake8_? See also the configuration in `<../../tox.ini>`__.\n\n  Check and solve issue from  :PEP:`290` - Code Migration and Modernization.\n  (Covers issues up to Python 2.4, is there an equivalent for more recent\n  modernizations?)\n\n  Ensure `backwards compatibility`_!\n\n  .. _flake8: https://pypi.org/project/flake8/\n  .. _backwards compatibility: policies.html#backwards-compatibility-policy\n\n* Encoding of command line arguments can only be guessed:\n\n  * try UTF-8/strict first, then try the locale's encoding with\n    strict error handling, then ASCII/replace?\n\n    UTF-8 is almost 100% safe to try first; false positives are rare,\n    The locale's encoding with strict error handling may be a\n    reasonable compromise, but any error would indicate that the\n    locale's encoding is inappropriate.  The only safe fallback is\n    ASCII/replace.\n\n  * Do not decode argv before option parsing but individual string\n    values?\n\n    +1  Allows for separate command-line vs. filesystem encodings,\n        respectively to keep file names encoded.\n    +1  Allows to configure command-line encoding in a config file,\n    -1  More complicated.\n\n  Cf. <http://thread.gmane.org/gmane.text.docutils.user/2890/focus=2957>.\n\n* Improve handling on Windows:\n\n  - Get graphical installer.\n  - Make rst2html.py an .exe file using py2exe.\n\n* .. _GUI:\n\n  The user interface is very difficult to use for most Windows users;\n  you can't really expect them to use the command line.  We need some\n  kind of GUI that can launch rst2html.py, and save the HTML output to\n  a file, and launch a browser.  What's important is that we get\n  settings to work with the GUI.  So we need some way to dynamically\n  generate a list of settings for the GUI.  The current settings_spec\n  for OptionParser doesn't seem to be usable for this for the\n  following reasons:\n\n  - It's biased toward the command line -- there are *two* options for\n    one boolean setting.\n\n  - You cannot have both a one-line description and a longer\n    description for tooltips/help-texts.\n\n  - It doesn't provide hints for the input type.  You cannot easily\n    infer the type of a setting from its validator, because any\n    component can add new validators.  In fact, it may be necessary to\n    have both a hint about the input type (e.g. string) and a\n    validator (valid ID), or it may be necessary to have a different\n    set of choices for the CLI (1, INFO, 2, ...) and for the GUI\n    (INFO, WARNING, ...).\n\n  - It's coupled to the OptionParser.  We want to be able to change\n    the underlying system without breaking everything.\n\n  - It's a bunch of primitive structures.  We want an extensible (thus\n    object-oriented) interface.\n\n  So we probably need to create a class for storing all the settings,\n  and auto-generate the OptionParser data from that.\n\n  I talked to Stephan Deibel about getting Docutils integrated into\n  Wing IDE.  He said it's possible, and he'd be willing to help.\n  There's a scripting interface to Wing, which we'd use.  We can\n  dynamically generate a list of preferences and not worry too much\n  about the rendering (from what I understood); Wing's whole GUI is\n  dynamic anyway.  The interface could be made usable for other GUIs.\n  For example, we could try to get option support for DocFactory.  //\n  FW\n\n* Allow different report levels for STDERR and system_messages inside\n  the document?\n\n* Change the docutils-update script (in sandbox/infrastructure), to\n  support arbitrary branch snapshots.\n\n* Move some general-interest sandboxes out of individuals'\n  directories, into subprojects?\n\n* Add option for file (and URL) access restriction to make Docutils\n  usable in Wikis and similar applications.\n\n  2005-03-21: added ``file_insertion_enabled`` & ``raw_enabled``\n  settings.  These partially solve the problem, allowing or disabling\n  **all** file accesses, but not limited access.\n\n* Configuration_ file handling needs discussion:\n\n  - There should be some error checking on the contents of config\n    files.  How much checking should be done?  How loudly should\n    Docutils complain if it encounters an error/problem?\n\n  - Docutils doesn't complain when it doesn't find a configuration\n    file supplied with the ``--config`` option.  Should it?  (If yes,\n    error or warning?)\n\n* Internationalization:\n\n  - I18n needs refactoring, the language dictionaries are difficult to\n    maintain.  Maybe have a look at gettext or similar tools.\n\n    (This would make a nice Google Summer of Code project)\n\n  - Language modules: in accented languages it may be useful to have\n    both accented and unaccented entries in the\n    ``bibliographic_fields`` mapping for versatility.\n\n  - Add a \"--strict-language\" option & setting: no English fallback\n    for language-dependent features.\n\n    Make this the default for output (as opposed to input)?\n    Throw an error with a helpful message, e.g.\n\n      Default \"contents\" title for language %s missing, please specify\n      an explicit title.\n\n    or\n\n     \"attention\" title for language %s missing, please use a generic\n     admonition with explicit title.\n\n  - Add internationalization to _`footer boilerplate text` (resulting\n    from \"--generator\", \"--source-link\", and \"--date\" etc.), allowing\n    translations.\n\n\n* Add validation?  See http://pytrex.sourceforge.net, RELAX NG, pyRXP.\n\n* In ``docutils.readers.get_reader_class`` (& ``parsers`` &\n  ``writers`` too), should we be importing \"standalone\" or\n  \"docutils.readers.standalone\"?  (This would avoid importing\n  top-level modules if the module name is not in docutils/readers.\n  Potential nastiness.)\n\n* Perhaps store a _`name-to-id mapping file`?  This could be stored\n  permanently, read by subsequent processing runs, and updated with\n  new entries.  (\"Persistent ID mapping\"?)\n\n* Perhaps the ``Component.supports`` method should deal with\n  individual features (\"meta\" etc.) instead of formats (\"html\" etc.)?\n  Currently, it is not used at all.\n\n  Do we need it at all?  Or rather let the writers just ignore some\n  nodes (like we already do for \"class\" values)?\n\n  The current implementation of the framework also leads to bug\n  `bug #241`__ \"doctree-based publishing != publish_string\".\n  The \"components.Filter\" transform is run by publish_doctree(). When\n  filtering based on the output format, it should be run by\n  publish_from_doctree() instead because only then the writer is\n  known.\n\n  So we need to either remove or fix the framework.\n\n  __ https://sourceforge.net/p/docutils/bugs/241/\n\n\n* Think about _`large documents` made up of multiple subdocument\n  files.  Issues: continuity (`persistent sequences`_ above),\n  cross-references (`name-to-id mapping file`_ above and `targets in\n  other documents`_ below), splitting (`document splitting`_ below).\n\n  When writing a book, the author probably wants to split it up into\n  files, perhaps one per chapter (but perhaps even more detailed).\n  However, we'd like to be able to have references from one chapter to\n  another, and have continuous numbering (pages and chapters, as\n  applicable).  Of course, none of this is implemented yet.  There has\n  been some thought put into some aspects; see `the \"include\"\n  directive`__ and the `Reference Merging`_ transform below.\n\n  When I was working with SGML in Japan, we had a system where there\n  was a top-level coordinating file, book.sgml, which contained the\n  top-level structure of a book: the <book> element, containing the\n  book <title> and empty component elements (<preface>, <chapter>,\n  <appendix>, etc.), each with filename attributes pointing to the\n  actual source for the component.  Something like this::\n\n      <book id=\"bk01\">\n      <title>Title of the Book</title>\n      <preface inrefid=\"pr01\"></preface>\n      <chapter inrefid=\"ch01\"></chapter>\n      <chapter inrefid=\"ch02\"></chapter>\n      <chapter inrefid=\"ch03\"></chapter>\n      <appendix inrefid=\"ap01\"></appendix>\n      </book>\n\n  (The \"inrefid\" attribute stood for \"insertion reference ID\".)\n\n  The processing system would process each component separately, but\n  it would recognize and use the book file to coordinate chapter and\n  page numbering, and keep a persistent ID to (title, page number)\n  mapping database for cross-references.  Docutils could use a similar\n  system for large-scale, multipart documents.\n\n  __ ../ref/rst/directives.html#including-an-external-document-fragment\n\n  Aahz's idea:\n\n      First the ToC::\n\n          .. ToC-list::\n              Introduction.txt\n              Objects.txt\n              Data.txt\n              Control.txt\n\n      Then a sample use::\n\n          .. include:: ToC.txt\n\n          As I said earlier in chapter :chapter:`Objects.txt`, the\n          reference count gets increased every time a binding is made.\n\n      Which produces::\n\n          As I said earlier in chapter 2, the\n          reference count gets increased every time a binding is made.\n\n      The ToC in this form doesn't even need to be references to actual\n      reST documents; I'm simply doing it that way for a minimum of\n      future-proofing, in case I do want to add the ability to pick up\n      references within external chapters.\n\n  Perhaps, instead of ToC (which would overload the \"contents\"\n  directive concept already in use), we could use \"manifest\".  A\n  \"manifest\" directive might associate local reference names with\n  files::\n\n      .. manifest::\n         intro: Introduction.txt\n         objects: Objects.txt\n         data: Data.txt\n         control: Control.txt\n\n  Then the sample becomes::\n\n      .. include:: manifest.txt\n\n      As I said earlier in chapter :chapter:`objects`, the\n      reference count gets increased every time a binding is made.\n\n* Add support for _`multiple output files` and _`generic data\n  handling`:\n\n  It should be possible for a component to **emit or reference** data\n  to be either **included or referenced** in the output document.\n  Examples of such data are stylesheets or images.\n\n  For this, we need a \"data\" object which stores the data either\n  inline or by referring to a file.  The Docutils framework is\n  responsible for either:\n\n  * storing the data in the appropriate location (e.g. in the\n    directory of the output file, or in a user-specified directory)\n    and providing the paths of the stored files to the writer, *or*\n\n  * providing the data itself to the writer so that it can be embedded\n    in the output document.\n\n  This approach decouples data handling from the data source (which\n  can either be embedded or referenced) and the destination (which can\n  either be embedded or referenced as well).\n\n  See <http://article.gmane.org/gmane.text.docutils.devel/3631>.\n\n* Add testing for Docutils' front end tools?\n\n* Publisher: \"Ordinary setup\" shouldn't require specific ordering; at\n  the very least, there ought to be error checking higher up in the\n  call chain.  [Aahz]\n\n  ``Publisher.get_settings`` requires that all components be set up\n  before it's called.  Perhaps the I/O *objects* shouldn't be set, but\n  I/O *classes*.  Then options are set up (``.set_options``), and\n  ``Publisher.set_io`` (or equivalent code) is called with source &\n  destination paths, creating the I/O objects.\n\n  Perhaps I/O objects shouldn't be instantiated until required.  For\n  split output, the Writer may be called multiple times, once for each\n  doctree, and each doctree should have a separate Output object (with\n  a different path).  Is the \"Builder\" pattern applicable here?\n\n* Perhaps I/O objects should become full-fledged components (i.e.\n  subclasses of ``docutils.Component``, as are Readers, Parsers, and\n  Writers now), and thus have associated option/setting specs and\n  transforms.\n\n* Multiple file I/O suggestion from Michael Hudson: use a file-like\n  object or something you can iterate over to get file-like objects.\n\n* Add an \"--input-language\" option & setting?  Specify a different\n  language module for input (bibliographic fields, directives) than\n  for output.  The \"--language\" option would set both input & output\n  languages.\n\n* Auto-generate reference tables for language-dependent features?\n  Could be generated from the source modules.  A special command-line\n  option could be added to Docutils front ends to do this.  (Idea from\n  Engelbert Gruber.)\n\n* Enable feedback of some kind from internal decisions, such as\n  reporting the successful input encoding.  Modify runtime settings?\n  System message?  Simple stderr output?\n\n* Rationalize Writer settings (HTML/LaTeX/PEP) -- share settings.\n\n* Add an \"--include file\" command-line option (config setting too?),\n  equivalent to \".. include:: file\" as the first line of the doc text?\n  Especially useful for character entity sets, text transform specs,\n  boilerplate, etc.\n\n* Support \"include\" as embedded inline-compatible directive in substitution\n  definitions, e.g. ::\n\n    .. |version| include:: version.txt\n\n    This document describes version |version| of ...\n\n  (cf. Grzegorz Adam Hankiewicz's post from 2014-10-01 in docutils-devel)\n\n* Add an ``:optional: <replacement text>`` option to the \"include\"\n  directive? This would not throw an error for a missing file, instead a\n  warning is given and ``<replacement text>`` is used instead. It would be\n  the responsibility of the author to ensure the missing file does not lead\n  to problems later in the document.\n\n  Use cases:\n\n  + Standard rST syntax to replace Sphinx's \"literalinclude\"::\n\n      .. include:: blah.cpp\n         :literal:\n         :optional: file ``blah.cpp`` not found\n\n  + Variable content taken from a file, e.g.\n\n    version.txt::\n\n       .. |version| replace:: 3.1\n\n    optionally used as::\n\n       .. include:: version.txt\n          :optional: .. |version| replace:: unknown\n\n       This document describes version |version| of ...\n\n    (cf. Grzegorz Adam Hankiewicz's post from 2014-10-01 in docutils-devel)\n\n* Parameterize the Reporter object or class?  See the `2004-02-18\n  \"rest checking and source path\"`_ thread.\n\n  .. _2004-02-18 \"rest checking and source path\":\n     http://thread.gmane.org/gmane.text.docutils.user/1112\n\n* Add a \"disable_transforms\" setting? Would allow for easy syntax\n  checking. Where (\"null\" writer, generic, parser(s))?\n  Cf. the `2004-02-18 \"rest checking and source path\"`_ thread.\n\n* Add a generic meta-stylesheet mechanism?  An external file could\n  associate style names (\"class\" attributes) with specific elements.\n  Could be generalized to arbitrary output attributes; useful for HTML\n  & XMLs.  Aahz implemented something like this in\n  sandbox/aahz/Effective/EffMap.py.\n\n* .. _classes for table cells:\n\n  William Dode suggested that table cells be assigned \"class\"\n  attributes by columns, so that stylesheets can affect text\n  alignment.  Unfortunately, there doesn't seem to be a way (in HTML\n  at least) to leverage the \"colspec\" elements (HTML \"col\" tags) by\n  adding classes to them.  The resulting HTML is very verbose::\n\n      <td class=\"col1\">111</td>\n      <td class=\"col2\">222</td>\n      ...\n\n  At the very least, it should be an option.  People who don't use it\n  shouldn't be penalized by increases in their HTML file sizes.\n\n  Table rows could also be assigned classes (like odd/even).  That\n  would be easier to implement.\n\n  How should it be implemented?\n\n  * There could be writer options (column classes & row classes) with\n    standard values.\n\n  * The table directive could grow some options.  Something like\n    \":cell-classes: col1 col2 col3\" (either must match the number of\n    columns, or repeat to fill?)  and \":row-classes: odd even\" (repeat\n    to fill; body rows only, or header rows too?).\n\n  Probably per-table directive options are best.  The \"class\" values\n  could be used by any writer, and applying such classes to all tables\n  in a document with writer options is too broad.\n\n  See also the `table_styling Sphinx extension`_ which defines\n\n  :widths: also in Docutils core (but different implementation)\n  :column-alignment: Sets per-column text alignment\n  :column-wrapping:  Sets per-column text wrapping\n  :column-dividers:  Add dividers between columns\n  :column-classes:   Add per-column css classes.\n  :header-columns:   Specify number of “stub” columns\n\n  .. _table_styling Sphinx extension: https://pythonhosted.org/cloud_sptheme/\n                                      lib/cloud_sptheme.ext.table_styling.html\n\n* Add file-specific settings support to config files, like::\n\n      [file index.txt]\n      compact-lists: no\n\n  Is this even possible?  Should the criterion be the name of the\n  input file or the output file?  Alternative (more explicit) syntax::\n\n      [source_file index.txt]\n      ...\n\n      [dest_file index.html]\n      ...\n\n  Or rather allow settings configuration from the rst source file\n  (see misc.settings_ directive)?\n\n* The \"validator\" support added to OptionParser is very similar to\n  \"traits_\" in SciPy_.  Perhaps something could be done with them?\n  (Had I known about traits when I was implementing docutils.frontend,\n  I may have used them instead of rolling my own.)\n\n  .. _traits: http://code.enthought.com/traits/\n  .. _SciPy: http://www.scipy.org/\n\n* tools/buildhtml.py: Extend the --prune option (\"prune\" config\n  setting) to accept file names (generic path) in addition to\n  directories (e.g. --prune=docs/user/rst/cheatsheet.txt, which should\n  *not* be converted to HTML).\n\n* Add support for _`plugins`.\n\n* _`Config directories`: Currently, ~/.docutils, ./docutils.conf/, &\n  /etc/docutils.conf are read as configuration_ files.  Proposal: allow\n  ~/.docutils to be a a configuration *directory*, along with\n  /etc/docutils/ and ./docutils.conf/.  Within these directories,\n  check for config.txt files.  We can also have subdirectories here,\n  for plugins, S5 themes, components (readers/writers/parsers) etc.\n\n  Docutils will continue to support configuration files for backwards\n  compatibility.\n\n* Add support for document decorations other than headers & footers?\n  For example, top/bottom/side navigation bars for web pages.  Generic\n  decorations?\n\n  Seems like a bad idea as long as it isn't independent from the output\n  format (for example, navigation bars are only useful for web pages).\n\n* docutils_update: Check for a ``Makefile`` in a directory, and run\n  ``make`` if found?  This would allow for variant processing on\n  specific source files, such as running rst2s5.py instead of\n  rst2html.py.\n\n* Add a \"disable table of contents\" setting?  The S5 writer could set\n  it as a default.  Rationale:\n\n      The ``contents`` (table of contents) directive must not be used\n      [in S5/HTML documents].  It changes the CSS class of headings\n      and they won't show up correctly in the screen presentation.\n\n      -- `Easy Slide Shows With reStructuredText & S5\n      <../user/slide-shows.html>`_\n\n  Analogue to the ``sectnum_xform`` setting, it could be used by the\n  latex writer to switch to a LaTeX generated ToC (currently, the latex\n  writer calls it \"use_latex_toc\").\n\nobject numbering and object references\n--------------------------------------\n\nFor equations, tables & figures.\n\nThese would be the equivalent of DocBook's \"formal\" elements.\n\nIn LaTeX, automatic counters are implemented for sections, equations and\nfloats (figures, tables) (configurable via stylesheets or in the\nlatex-preamble). Objects can be given `reference names`_ with the\n``\\label{<refname}`` command, ``\\ref{<refname>}`` inserts the\ncorresponding number.\n\nNo such mechanism exists in HTML.\n\n* We need _`persistent sequences`, similar to chapter and footnote\n  numbers. See `OpenOffice.org XML`_ \"fields\".\n\n  - Should the sequences be automatic or manual (user-specifyable)?\n\n* It is already possible to give `reference names`_ to objects via\n  internal hyperlink targets or the \"name\" directive option::\n\n      .. _figure name:\n\n      .. figure:: image.png\n\n  or ::\n\n      .. figure:: image.png\n         :name: figure name\n\n  Improve the mapping of \"phrase references\" to IDs/labels with Literal\n  transcription (i.e. ü -> ue, ß -> ss, å -> aa) instead of just\n  stripping the accents and other non-ASCII chars.

See the first paragraphs in\n  <http://article.gmane.org/gmane.text.docutils.user/1584>.\n\n* Add document about what Docutils has previously been used for\n  (web/use-cases.txt?).\n\n* Improve index in docs/user/config.txt.\n\n\nDeveloper Docs\n--------------\n\n* Improve the internal module documentation (docstrings in the code).\n  Specific deficiencies listed below.\n\n  - docutils.parsers.rst.states.State.build_table: data structure\n    required (including StringList).\n\n  - docutils.parsers.rst.states: more complete documentation of parser\n    internals.\n\n* docs/ref/doctree.txt: DTD element structural relationships,\n  semantics, and attributes.  In progress; element descriptions to be\n  completed.\n\n* Document the ``pending`` elements, how they're generated and what\n  they do.\n\n* Document the transforms_ (perhaps in docstrings?): how they're used,\n  what they do, dependencies & order considerations.\n\n* Document the HTML classes used by html4css1.py.\n\n* Write an overview of the Docutils architecture, as an introduction\n  for developers.  What connects to what, why, and how.  Either update\n  PEP 258 (see PEPs_ below) or as a separate doc.\n\n* Give information about unit tests.  Maybe as a howto?\n\n* Document the docutils.nodes APIs.\n\n* Complete the docs/api/publisher.txt docs.\n\n\nHow-Tos\n-------\n\n* Creating Docutils Writers\n\n* Creating Docutils Readers\n\n* Creating Docutils Transforms_\n\n* Creating Docutils Parsers\n\n* Using Docutils as a Library\n\n\nPEPs\n----\n\n* Complete PEP 258 Docutils Design Specification.\n\n  - Fill in the blanks in API details.\n\n  - Specify the nodes.py internal data structure implementation?\n\n        [Tibs:] Eventually we need to have direct documentation in\n        there on how it all hangs together - the DTD is not enough\n        (indeed, is it still meant to be correct?  [Yes, it is.\n        --DG]).\n\n* Rework PEP 257, separating style from spec from tools, wrt Docutils?\n  See Doc-SIG from 2001-06-19/20.\n\n\nPython Source Reader\n====================\n\nGeneral:\n\n* Analyze Tony Ibbs' PySource code.\n\n* Analyze Doug Hellmann's HappyDoc project.\n\n* Investigate how POD handles literate programming.\n\n* Take the best ideas and integrate them into Docutils.\n\nMiscellaneous ideas:\n\n* Ask Python-dev for opinions (GvR for a pronouncement) on special\n  variables (__author__, __version__, etc.): convenience vs. namespace\n  pollution.  Ask opinions on whether or not Docutils should recognize\n  & use them.\n\n* If we can detect that a comment block begins with ``##``, a la\n  JavaDoc, it might be useful to indicate interspersed section headers\n  & explanatory text in a module.  For example::\n\n      \"\"\"Module docstring.\"\"\"\n\n      ##\n      # Constants\n      # =========\n\n      a = 1\n      b = 2\n\n      ##\n      # Exception Classes\n      # =================\n\n      class MyException(Exception): pass\n\n      # etc.\n\n* Should standalone strings also become (module/class) docstrings?\n  Under what conditions?  We want to prevent arbitrary strings from\n  becoming docstrings of prior attribute assignments etc.  Assume\n  that there must be no blank lines between attributes and attribute\n  docstrings?  (Use lineno of NEWLINE token.)\n\n  Triple-quotes are sometimes used for multi-line comments (such as\n  commenting out blocks of code).  How to reconcile?\n\n* HappyDoc's idea of using comment blocks when there's no docstring\n  may be useful to get around the conflict between `additional\n  docstrings`_ and ``from __future__ import`` for module docstrings.\n  A module could begin like this::\n\n      #!/usr/bin/env python\n      # :Author: Me\n      # :Copyright: whatever\n\n      \"\"\"This is the public module docstring (``__doc__``).\"\"\"\n\n      # More docs, in comments.\n      # All comments at the beginning of a module could be\n      # accumulated as docstrings.\n      # We can't have another docstring here, because of the\n      # ``__future__`` statement.\n\n      from __future__ import division\n\n  Using the JavaDoc convention of a doc-comment block beginning with\n  ``##`` is useful though.  It allows doc-comments and implementation\n  comments.\n\n  .. _additional docstrings:\n     ../peps/pep-0258.html#additional-docstrings\n\n* HappyDoc uses an initial comment block to set \"parser configuration\n  values\".  Do the same thing for Docutils, to set runtime settings on\n  a per-module basis?  I.e.::\n\n      # Docutils:setting=value\n\n  Could be used to turn on/off function parameter comment recognition\n  & other marginal features.  Could be used as a general mechanism to\n  augment config files and command-line options (but which takes\n  precedence?).\n\n* Multi-file output should be divisible at arbitrary level.\n\n* Support all forms of ``import`` statements:\n\n  - ``import module``: listed as \"module\"\n  - ``import module as alias``: \"alias (module)\"\n  - ``from module import identifier``: \"identifier (from module)\"\n  - ``from module import identifier as alias``: \"alias (identifier\n    from module)\"\n  - ``from module import *``: \"all identifiers (``*``) from module\"\n\n* Have links to colorized Python source files from API docs?  And\n  vice-versa: backlinks from the colorized source files to the API\n  docs!\n\n* In summaries, use the first *sentence* of a docstring if the first\n  line is not followed by a blank line.\n\n\nreStructuredText Parser\n=======================\n\nAlso see the `... Or Not To Do?`__ list.\n\n__ rst/alternatives.html#or-not-to-do\n\nBugs\n----\n\n* A container directive with ``:class:`` option gets the spurious\n  class value \"class\".\n\nMisc\n----\n\n* Another list problem::\n\n      * foo\n            * bar\n            * baz\n\n  This ends up as a definition list.  This is more of a usability\n  issue.\n\n* This case is probably meant to be a nested list, but it ends up as a\n  list inside a block-quote without an error message::\n\n      - foo\n\n       - bar\n\n  It should probably just be an error.\n\n  The problem with this is that you don't notice easily in HTML that\n  it's not a nested list but a block-quote -- there's not much of a\n  visual difference.\n\n* Treat enumerated lists that are not arabic and consist of only one\n  item in a single line as ordinary paragraphs.  See\n  <http://article.gmane.org/gmane.text.docutils.user/2635>.\n\n* The citation syntax could use some improvements.  See\n  <http://thread.gmane.org/gmane.text.docutils.user/2499> (and the\n  sub-thread at\n  <http://thread.gmane.org/gmane.text.docutils.user/2499/focus=3028>,\n  and the follow-ups at\n  <http://thread.gmane.org/gmane.text.docutils.user/3087>,\n  <http://thread.gmane.org/gmane.text.docutils.user/3110>,\n  <http://thread.gmane.org/gmane.text.docutils.user/3114>),\n  <http://thread.gmane.org/gmane.text.docutils.user/2443>,\n  <http://thread.gmane.org/gmane.text.docutils.user/2715>,\n  <http://thread.gmane.org/gmane.text.docutils.user/3027>,\n  <http://thread.gmane.org/gmane.text.docutils.user/3120>,\n  <http://thread.gmane.org/gmane.text.docutils.user/3253>.\n\n* The current list-recognition logic has too many false positives, as\n  in ::\n\n      * Aorta\n      * V. cava superior\n      * V. cava inferior\n\n  Here ``V.`` is recognized as an enumerator, which leads to\n  confusion.  We need to find a solution that resolves such problems\n  without complicating the spec to much.\n\n  See <http://thread.gmane.org/gmane.text.docutils.user/2524>.\n\n* Add indirect links via citation references & footnote references.\n  Example::\n\n      `Goodger (2005)`_ is helpful.\n\n      .. _Goodger (2005): [goodger2005]_\n      ..

(Test\n  code needs to check if PIL is available on the system.)\n\n* Add support for CJK double-width whitespace (indentation) &\n  punctuation characters (markup; e.g. double-width \"*\", \"-\", \"+\")?\n\n* Add motivation sections for constructs in spec.\n\n* Support generic hyperlink references to _`targets in other\n  documents`?  Not in an HTML-centric way, though (it's trivial to say\n  ``https://www.example.org/doc#name``, and useless in non-HTML\n  contexts).  XLink/XPointer?  ``.. baseref::``?  See Doc-SIG\n  2001-08-10.\n\n* Implement the header row separator modification to table.el.  (Wrote\n  to Takaaki Ota & the table.el mailing list on 2001-08-12, suggesting\n  support for \"=====\" header rows.  On 2001-08-17 he replied, saying\n  he'd put it on his to-do list, but \"don't hold your breath\".)\n\n* Fix the parser's indentation handling to conform with the stricter\n  definition in the spec.  (Explicit markup blocks should be strict or\n  forgiving?)\n\n  .. XXX What does this mean?  Can you elaborate, David?\n\n* Make the parser modular.  Allow syntax constructs to be added or\n  disabled at run-time.  Subclassing is probably not enough because it\n  makes it difficult to apply multiple extensions.\n\n* Generalize the \"doctest block\" construct (which is overly\n  Python-centric) to other interactive sessions?  \"Doctest block\"\n  could be renamed to \"I/O block\" or \"interactive block\", and each of\n  these could also be recognized as such by the parser:\n\n  - Shell sessions::\n\n        $ cat example1.txt\n        A block beginning with a \"$ \" prompt is interpreted as a shell\n        session interactive block.  As with Doctest blocks, the\n        interactive block ends with the first blank line, and wouldn't\n        have to be indented.\n\n  - Root shell sessions::\n\n        # cat example2.txt\n        A block beginning with a \"# \" prompt is interpreted as a root\n        shell session (the user is or has to be logged in as root)\n        interactive block.  Again, the block ends with a blank line.\n\n  Other standard (and unambiguous) interactive session prompts could\n  easily be added (such as \"> \" for WinDOS).\n\n  Tony Ibbs spoke out against this idea (2002-06-14 Doc-SIG thread\n  \"docutils feedback\").\n\n* Add support for pragma (syntax-altering) directives.\n\n  Some pragma directives could be local-scope unless explicitly\n  specified as global/pragma using \":global:\" options.\n\n* Support whitespace in angle-bracketed standalone URLs according to\n  Appendix E (\"Recommendations for Delimiting URI in Context\") of `RFC\n  2396`_.\n\n  .. _RFC 2396: https://www.rfc-editor.org/rfc/rfc2396.txt\n\n* Use the vertical spacing of the source text to determine the\n  corresponding vertical spacing of the output?\n\n* [From Mark Nodine]  For cells in simple tables that comprise a\n  single line, the justification can be inferred according to the\n  following rules:\n\n  1. If the text begins at the leftmost column of the cell,\n     then left justification, ELSE\n  2. If the text begins at the rightmost column of the cell,\n     then right justification, ELSE\n  3. Center justification.\n\n  The onus is on the author to make the text unambiguous by adding\n  blank columns as necessary.  There should be a parser setting to\n  turn off justification-recognition (normally on would be fine).\n\n  Decimal justification?\n\n  All this shouldn't be done automatically.  Only when it's requested\n  by the user, e.g. with something like this::\n\n      .. table::\n         :auto-indent:\n\n         (Table goes here.)\n\n  Otherwise it will break existing documents.\n\n* Generate a warning or info message for paragraphs which should have\n  been lists, like this one::\n\n      1. line one\n      3. line two\n\n* Generalize the \"target-notes\" directive into a command-line option\n  somehow?  See docutils-develop 2003-02-13.\n\n* Allow a \"::\"-only paragraph (first line, actually) to introduce a\n  _`literal block without a blank line`?  (Idea from Paul Moore.) ::\n\n      ::\n          This is a literal block\n\n  Is indentation enough to make the separation between a paragraph\n  which contains just a ``::`` and the literal text unambiguous?\n  (There's one problem with this concession: If one wants a definition\n  list item which defines the term \"::\", we'd have to escape it.)  It\n  would only be reasonable to apply it to \"::\"-only paragraphs though.\n  I think the blank line is visually necessary if there's text before\n  the \"::\"::\n\n      The text in this paragraph needs separation\n      from the literal block following::\n          This doesn't look right.\n\n* Add new syntax for _`nested inline markup`?  Or extend the parser to\n  parse nested inline markup somehow?  See the `collected notes\n  <rst/alternatives.html#nested-inline-markup>`__.\n\n* Drop the backticks from embedded URIs with omitted reference text?\n  Should the angle brackets be kept in the output or not? ::\n\n      <file_name>_\n\n  Probably not worth the trouble.\n\n* How about a syntax for alternative hyperlink behavior, such as \"open\n  in a new window\" (as in HTML's ``<a target=\"_blank\">``)?\n\n  The MoinMoin wiki uses a caret (\"^\") at the beginning of the URL\n  (\"^\" is not a legal URI character).  That could work for both inline\n  and explicit targets::\n\n      The `reference docs <^url>`__ may be handy.\n\n      .. _name: ^url\n\n  This may be too specific to HTML.  It hasn't been requested very\n  often either.\n\n* Add an option to add URI schemes at runtime.\n\n* _`Segmented lists`::\n\n      : segment : segment : segment\n      : segment : segment : very long\n        segment\n      : segment : segment : segment\n\n  The initial colon (\":\") can be thought of as a type of bullet\n\n  We could even have segment titles::\n\n      :: title  : title   : title\n      : segment : segment : segment\n      : segment : segment : segment\n\n  This would correspond well to DocBook's SegmentedList.  Output could\n  be tabular or \"name: value\" pairs, as described in DocBook's docs.\n\n* Enable grid _`tables inside XML comments`, where \"``--``\" ends comments.\n\n  Implementation possibilities:\n\n  1. Make the table syntax characters into \"table\" directive options.\n     This is the most flexible but most difficult, and we probably\n     don't need that much flexibility.\n\n  2. Substitute \"~\" for \"-\" with a specialized directive option\n     (e.g. \":tildes:\").\n\n  3. Make the standard table syntax recognize \"~\" as well as \"-\", even\n     without a directive option.  Individual tables would have to be\n     internally consistent.\n\n  4. Allow Unicode box characters for table markup\n     (`feature request [6]`_)\n\n  Directive options are preferable to configuration settings, because\n  tables are document-specific.  A pragma directive would be another\n  approach, to set the syntax once for a whole document.\n\n  Unicode box character markup would kill two birds with one stone.\n\n  In the meantime, the list-table_ directive is a good replacement for\n  grid tables inside XML comments.\n\n  .. _feature request [6]:\n      https://sourceforge.net/p/docutils/feature-requests/6\n  .. _list-table: ../ref/rst/directives.html#list-table\n\n\n* Generalize docinfo contents (bibliographic fields): remove specific\n  fields, and have only a single generic \"field\"?\n\n* _`Line numbers` and \"source\" in system messages:\n\n  - Add \"source\" and \"line\" keyword arguments to all Reporter calls?\n    This would require passing source/line arguments along all\n    intermediate functions (where currently only `line` is used).\n\n    Or rather specify \"line\" only if actually needed?\n\n    Currently, `document.reporter` uses a state machine instance to\n    determine the \"source\" and \"line\" info from\n    `statemachine.input_lines` if not given explicitly. Except for\n    special cases, the \"line\" argument is not needed because,\n    `document.statemachine` keeps record of the current line number.\n\n  - For system messages generated after the parsing is completed (i.e. by\n    transforms or the writer) \"line\" info must be present in the doctree\n    elements.\n\n    Elements' .line assignments should be checked.  (Assign to .source\n    too?  Add a set_info method?  To what?)\n\n    The \"source\" (and line number in the source) can either be added\n    explicitly to the elements or determined from the “raw” line\n    number by `document.statemachine.get_source_and_line`.\n\n  - Some line numbers in elements are not being set properly\n    (explicitly), just implicitly/automatically.  See rev. 1.74 of\n    docutils/parsers/rst/states.py for an example of how to set.\n\n  - The line numbers of definition list items are wrong::\n\n        $ rst2pseudoxml.py --expose-internal-attribute line\n        1\n          2\n          3\n\n        5\n          6\n          7\n\n        <document source=\"<stdin>\">\n            <definition_list>\n                <definition_list_item internal:line=\"3\">\n                    <term>\n                        1\n                    <definition>\n                        <paragraph internal:line=\"2\">\n                            2\n                            3\n                <definition_list_item internal:line=\"6\">\n                    <term>\n                        5\n                    <definition>\n                        <paragraph internal:line=\"6\">\n                            6\n                            7\n\n* .. _none source:\n\n  Quite a few nodes are getting a \"None\" source attribute as well.  In\n  particular, see the bodies of definition lists.\n\n\nAdaptable file extensions\n-------------------------\n\nQuestions\n`````````\n\nShould Docutils support adaptable file extensions in hyperlinks?\n\n  In the rST source, sister documents are \".txt\" files. If we're\n  generating HTML, then \".html\" is appropriate; if PDF, then \".pdf\";\n  etc.\n\nHandle documents only, or objects (images, etc.) also?\n\n  Different output formats support different sets of image formats (HTML\n  supports \".svg\" but not \".pdf\", pdfLaTeX supports \".pdf\" but not \".svg\",\n  LaTeX supports only \".eps\").\n\n  This is less urgent 2020 than 2004, as `pdflatex` and `lualatex` are\n  now standard and support most image formats. Also, a wrapper like\n  `rubber`__ that provides on-the-fly image conversion depends on the\n  \"wrong\" extension in the LaTeX source.\n\n  __ https://pypi.org/project/rubber/\n\nAt what point should the extensions be substituted?\n\n  Transforms_:\n    Fits well in the `Reader → Transformer → Writer`__ processing framework.\n\n    * Filename/URL extension replacement can be done walking over the\n      Document tree transforming the document tree from a valid state\n      to another valid state.\n\n    * Writer-specific configuration is still possible in the\n      respective sections of the configuration_ file.\n\n    __ ../peps/pep-0258.html#id24\n\n  Pre- or post-processing:\n    Can be implemented independent of Docutils -- keeps Docutils simple.\n\n      ... those who need more sophisticated filename extension\n      tweaking can simply use regular expressions, which isn't too\n      difficult due to the determinability of the writers.

(like the \"raw\" role)\n\n__ https://sourceforge.net/p/docutils/mailman/message/6919484/\n\n\nIdea from Jim Fulton: an external lookup table of targets:\n\n    I would like to specify the extension (e.g. .txt) [in the\n    source, rather than ``filename.*``], but tell the converter to\n    change references to the files anticipating that the files will\n    be converted too.\n\n    For example::\n\n      .. _Another Document: another.txt\n\n      rst2html.py --convert-links \"another.txt bar.txt\" foo.txt\n\n    That is, name the files for which extensions should be converted.\n\n    Note that I want to refer to original files in the original text\n    (another.txt rather than another.*) because I want the\n    unconverted text to stand on its own.\n\n    Note that in most cases, people will be able to use globs::\n\n      rst2html.py --convert-link-extensions-for \"`echo *.txt`\" foo.txt\n\n    It might be nice to be able to use multiple arguments, as in::\n\n      rst2html.py --convert-link-extensions-for *.txt -- foo.txt\n\n    > Handle documents only, or objects (images, etc.) also?\n\n    No, documents only, but there really is no need for guesswork.\n    Just get the file names as command-line arguments.  EIBTI\n    [explicit is better than implicit].\n\nIn `Patch #169`__ `Hyperlink extension rewriting`, John L.

For example, you\n    might want to get characters or strings with borders around them.\n\n  - _`images.figure`: \"title\" and \"number\", to indicate a formal\n    figure?\n\n  - _`parts.sectnum`: \"local\"?, \"refnum\"\n\n    A \"local\" option could enable numbering for sections from a\n    certain point down, and sections in the rest of the document are\n    not numbered.  For example, a reference section of a manual might\n    be numbered, but not the rest.  OTOH, an all-or-nothing approach\n    would probably be enough.\n\n    The \"sectnum\" directive should be usable multiple times in a\n    single document.  For example, in a long document with \"chapter\"\n    and \"appendix\" sections, there could be a second \"sectnum\" before\n    the first appendix, changing the sequence used (from 1,2,3... to\n    A,B,C...).  This is where the \"local\" concept comes in.  This part\n    of the implementation can be left for later.\n\n    A \"refnum\" option (better name?) would insert reference names\n    (targets) consisting of the reference number.  Then a URL could be\n    of the form ``http://host/document.html#2.5`` (or \"2-5\"?).  Allow\n    internal references by number?  Allow name-based *and*\n    number-based ids at the same time, or only one or the other (which\n    would the table of contents use)?  Usage issue: altering the\n    section structure of a document could render hyperlinks invalid.\n\n  - _`parts.contents`: Add a \"suppress\" or \"prune\" option?  It would\n    suppress contents display for sections in a branch from that point\n    down.  Or a new directive, like \"prune-contents\"?\n\n    Add an option to include topics in the TOC?  Another for sidebars?\n    The \"topic\" directive could have a \"contents\" option, or the\n    \"contents\" directive\" could have an \"include-topics\" option.  See\n    docutils-develop 2003-01-29.\n\n  - _`parts.header` & _`parts.footer`: Support multiple, named headers\n    & footers?  For example, separate headers & footers for odd, even,\n    and the first page of a document.\n\n    This may be too specific to output formats which have a notion of\n    \"pages\".\n\n  - _`misc.class`:\n\n    - Add a ``:parent:`` option for setting the parent's class\n      (http://article.gmane.org/gmane.text.docutils.devel/3165).\n\n  - _`misc.include`:\n\n    - Option to label lines?\n\n    - How about an environment variable, say RSTINCLUDEPATH or\n      RSTPATH, for standard includes (as in ``.. include:: <name>``)?\n      This could be combined with a setting/option to allow\n      user-defined include directories.\n\n    - Add support for inclusion by URL? ::\n\n          .. include::\n             :url: https://www.example.org/inclusion.txt\n\n    - Strip blank lines from begin and end of a literal included file or\n      file section. This would correspond to the way a literal block is\n      handled.\n\n      As nodes.literal_block expects (and we have) the text as a string\n      (rather than a list of lines), using a regexp seems the way.\n\n  - _`misc.raw`: add a \"destination\" option to the \"raw\" directive? ::\n\n        .. raw:: html\n           :destination: head\n\n           <link ...>\n\n    It needs thought & discussion though, to come up with a consistent\n    set of destination labels and consistent behavior.\n\n    And placing HTML code inside the <head> element of an HTML\n    document is rather the job of a templating system.\n\n  - _`body.sidebar`: Allow internal section structure?  Adornment\n    styles would be independent of the main document.\n\n    That is really complicated, however, and the document model\n    greatly benefits from its simplicity.\n\n* Implement directives.  Each of the list items below begins with an\n  identifier of the form, \"module_name.directive_function_name\".  The\n  directive name itself could be the same as the\n  directive_function_name, or it could differ.\n\n  - _`html.imagemap`\n\n    It has the disadvantage that it's only easily implementable for\n    HTML, so it's specific to one output format.\n\n    (For non-HTML writers, the imagemap would have to be replaced with\n    the image only.)\n\n  - _`parts.endnotes` (or \"footnotes\"): See `Footnote & Citation Gathering`_.\n\n  - _`parts.citations`: See `Footnote & Citation Gathering`_.\n\n  - _`misc.language`: Specify (= change) the language of a document at\n    parse time?\n\n    * The misc.settings_ directive suggested below offers a more generic\n      approach.\n\n    * The language of document parts can be indicated by the \"special class\n      value\" ``\"language-\"`` + `BCP 47`_ language code. Class arguments to\n      the title are attached to the document's base node - hence titled\n      documents can be given a different language at parse time. However,\n      \"language by class attribute\" does not change parsing (localized\n      directives etc.), only supporting writers.\n\n    .. _BCP 47: https://www.rfc-editor.org/rfc/bcp/bcp47.txt\n\n\n  - _`misc.settings`: Set any(?) Docutils runtime setting from within\n    a document?  Needs much thought and discussion.\n\n    Security concerns need to be taken into account (it shouldn't be\n    possible to enable ``file_insertion_enabled`` from within a\n    document), and settings that only would have taken effect before\n    the directive (like ``tab-width``) shouldn't be accessible either.\n\n    See this sub-thread:\n    <http://thread.gmane.org/gmane.text.docutils.user/3620/focus=3649>\n\n  - _`misc.gather`: Gather (move, or copy) all instances of a specific\n    element.  A generalization of the `Footnote & Citation Gathering`_\n    ideas.\n\n  - Add a custom \"directive\" directive, equivalent to \"role\"?  For\n    example::\n\n        .. directive:: incr\n\n           .. class:: incremental\n\n        .. incr::\n\n        \"``.. incr::``\" above is equivalent to \"``.. class:: incremental``\".\n\n    Another example::\n\n        .. directive:: printed-links\n\n           .. topic:: Links\n              :class: print-block\n\n              .. target-notes::\n                 :class: print-inline\n\n    This acts like macros.  The directive contents will have to be\n    evaluated when referenced, not when defined.\n\n    * Needs a better name?  \"Macro\", \"substitution\"?\n    * What to do with directive arguments & options when the\n      macro/directive is referenced?\n\n  - Make the meaning of block quotes overridable?  Only a 1-shot\n    though; doesn't solve the general problem.\n\n  - _`conditional directives`:\n\n    .. note:: See also the implementation in Sphinx_.\n\n    Docutils already has the ability to say \"use this content for\n    Writer X\" via the \"raw\" directive. It also does have the ability\n    to say \"use this content for any Writer other than X\" via the\n    \"strip-elements with class\" config value.  However, using \"raw\"\n    input just to select a special writer is inconvenient in many\n    cases.\n    It wouldn't be difficult to get more straightforward support, though.\n\n    My first idea would be to add a set of conditional directives.\n    Let's call them \"writer-is\" and \"writer-is-not\" for discussion\n    purposes (don't worry about implementation details).  We might\n    have::\n\n         .. writer-is:: text-only\n\n            ::\n\n                +----------+\n                |   SNMP   |\n                +----------+\n                |   UDP    |\n                +----------+\n                |    IP    |\n                +----------+\n                | Ethernet |\n                +----------+\n\n         .. writer-is:: pdf\n\n            .. figure:: protocol_stack.eps\n\n         .. writer-is-not:: text-only pdf\n\n            .. figure:: protocol_stack.png\n\n    This could be an interface to the Filter transform\n    (docutils.transforms.components.Filter).\n\n    The ideas in the `adaptable file extensions`_ section above may\n    also be applicable here.\n\n    SVG's \"switch\" statement may provide inspiration.\n\n    Here's an example of a directive that could produce multiple\n    outputs (*both* raw troff pass-through *and* a GIF, for example)\n    and allow the Writer to select. ::\n\n        .. eqn::\n\n           .EQ\n           delim %%\n           .EN\n           %sum from i=o to inf c sup i~=~lim from {m -> inf}\n           sum from i=0 to m sup i%\n           .EQ\n           delim off\n           .EN\n\n  - _`body.example`: Examples; suggested by Simon Hefti.  Semantics as\n    per Docbook's \"example\"; admonition-style, numbered, reference,\n    with a caption/title.\n\n  - _`body.index`: Index targets.\n\n    See `Index Entries & Indexes\n    <./rst/alternatives.html#index-entries-indexes>`__.\n\n  - _`body.literal`: Literal block, possibly \"formal\" (see `object\n    numbering and object references`_ above).  Possible options:\n\n    - \"highlight\" a range of lines\n\n    - include only a specified range of lines\n\n    - \"number\" or \"line-numbers\"? (since 0.9 available with \"code\" directive)\n\n    - \"styled\" could indicate that the directive should check for\n      style comments at the end of lines to indicate styling or\n      markup.\n\n      Specific derivatives (i.e., a \"python-interactive\" directive)\n      could interpret style based on cues, like the \">>> \" prompt and\n      \"input()\"/\"raw_input()\" calls.\n\n    See docutils-users 2003-03-03.\n\n  - _`body.listing`: Code listing with title (to be numbered\n    eventually), equivalent of \"figure\" and \"table\" directives.\n\n  - _`pysource.usage`: Extract a usage message from the program,\n    either by running it at the command line with a ``--help`` option\n    or through an exposed API.  [Suggestion for Optik.]\n\n  - _`body.float`: Generic float that can be used for figures, tables,\n    code listings, flowcharts, ...\n\n    There is a Sphinx extension by Ignacio Fernández Galván <jellby@gmail.com>\n\n       I implemented something for generic floats in sphinx, and submitted a\n       pull request that is still waiting::\n\n        .. float::\n           :type: figure\n           :caption: My caption\n\n      https://github.com/sphinx-doc/sphinx/pull/1858\n\n\nInterpreted Text\n----------------\n\nInterpreted text is entirely a reStructuredText markup construct, a\nway to get around built-in limitations of the medium.  Some roles are\nintended to introduce new doctree elements, such as \"title-reference\".\nOthers are merely convenience features, like \"RFC\".\n\nAll supported interpreted text roles must already be known to the\nParser when they are encountered in a document.  Whether pre-defined\nin core/client code, or in the document, doesn't matter; the roles\njust need to have already been declared.  Adding a new role may\ninvolve adding a new element to the DTD and may require extensive\nsupport, therefore such additions should be well thought-out.  There\nshould be a limited number of roles.\n\nThe only place where no limit is placed on variation is at the start,\nat the Reader/Parser interface.  Transforms are inserted by the Reader\ninto the Transformer's queue, where non-standard elements are\nconverted.  Once past the Transformer, no variation from the standard\nDocutils doctree is possible.\n\nAn example is the Python Source Reader, which will use interpreted\ntext extensively.  The default role will be \"Python identifier\", which\nwill be further interpreted by namespace context into <class>,\n<method>, <module>, <attribute>, etc. elements (see pysource.dtd),\nwhich will be transformed into standard hyperlink references, which\nwill be processed by the various Writers.  No Writer will need to have\nany knowledge of the Python-Reader origin of these elements.\n\n* Add explicit interpreted text roles for the rest of the implicit\n  inline markup constructs: named-reference, anonymous-reference,\n  footnote-reference, citation-reference, substitution-reference,\n  target, uri-reference (& synonyms).\n\n* Add directives for each role as well?  This would allow indirect\n  nested markup::\n\n      This text contains |nested inline markup|.\n\n      .. |nested inline markup| emphasis::\n\n         nested ``inline`` markup\n\n* Implement roles:\n\n  - \"_`raw-wrapped`\" (or \"_`raw-wrap`\"): Base role to wrap raw text\n    around role contents.\n\n    For example, the following reStructuredText source ... ::\n\n        .. role:: red(raw-formatting)\n           :prefix:\n               :html: <font color=\"red\">\n               :latex: {\\color{red}\n           :suffix:\n               :html: </font>\n               :latex: }\n\n        colored :red:`text`\n\n    ... will yield the following document fragment::\n\n        <paragraph>\n            colored\n            <inline classes=\"red\">\n                <raw format=\"html\">\n                    <font color=\"red\">\n                <raw format=\"latex\">\n                    {\\color{red}\n                <inline classes=\"red\">\n                    text\n                <raw format=\"html\">\n                    </font>\n                <raw format=\"latex\">\n                    }\n\n    Possibly without the intermediate \"inline\" node.\n\n  - _`\"acronym\" and \"abbreviation\"`: Associate the full text with a\n    short form.  Jason Diamond's description:\n\n        I want to translate ```reST`:acronym:`` into ``<acronym\n        title='reStructuredText'>reST</acronym>``.  The value of the\n        title attribute has to be defined out-of-band since you can't\n        parameterize interpreted text.  Right now I have them in a\n        separate file but I'm experimenting with creating a directive\n        that will use some form of reST syntax to let you define them.\n\n    Should Docutils complain about undefined acronyms or\n    abbreviations?\n\n    What to do if there are multiple definitions?  How to\n    differentiate between CSS (Content Scrambling System) and CSS\n    (Cascading Style Sheets) in a single document?  David Priest\n    responds,\n\n        The short answer is: you don't.  Anyone who did such a thing\n        would be writing very poor documentation indeed.  (Though I\n        note that `somewhere else in the docs`__, there's mention of\n        allowing replacement text to be associated with the\n        abbreviation.  That takes care of the duplicate\n        acronyms/abbreviations problem, though a writer would be\n        foolish to ever need it.)\n\n        __ `inline parameter syntax`_\n\n    How to define the full text?  Possibilities:\n\n    1. With a directive and a definition list? ::\n\n           .. acronyms::\n\n              reST\n                  reStructuredText\n              DPS\n                  Docstring Processing System\n\n       Would this list remain in the document as a glossary, or would\n       it simply build an internal lookup table?  A \"glossary\"\n       directive could be used to make the intention clear.\n       Acronyms/abbreviations and glossaries could work together.\n\n       Then again, a glossary could be formed by gathering individual\n       definitions from around the document.\n\n    2. Some kind of `inline parameter syntax`_? ::\n\n           `reST <reStructuredText>`:acronym: is `WYSIWYG <what you\n           see is what you get>`:acronym: plaintext markup.\n\n       .. _inline parameter syntax:\n          rst/alternatives.html#parameterized-interpreted-text\n\n    3. A combination of 1 & 2?\n\n       The multiple definitions issue could be handled by establishing\n       rules of priority.  For example, directive-based lookup tables\n       have highest priority, followed by the first inline definition.\n       Multiple definitions in directive-based lookup tables would\n       trigger warnings, similar to the rules of `implicit hyperlink\n       targets`__.\n\n       __ ../ref/rst/restructuredtext.html#implicit-hyperlink-targets\n\n    4. Using substitutions? ::\n\n           .. |reST| acronym:: reST\n              :text: reStructuredText\n\n    What do we do for other formats than HTML which do not support\n    tool tips?  Put the full text in parentheses?\n\n  - \"figure\", \"table\", \"listing\", \"chapter\", \"page\", etc: See `object\n    numbering and object references`_ above.\n\n  - \"glossary-term\": This would establish a link to a glossary.  It\n    would require an associated \"glossary-entry\" directive, whose\n    contents could be a definition list::\n\n        .. glossary-entry::\n\n           term1\n               definition1\n           term2\n               definition2\n\n    This would allow entries to be defined anywhere in the document,\n    and collected (via a \"glossary\" directive perhaps) at one point.\n\n\nDoctree pruning\n---------------\n\n[DG 2017-01-02: These are not definitive to-dos, just one developer's\nopinion. Added 2009-10-13 by Günter Milde, in r6178.]\n[Updated by GM 2017-02-04]\n\nThe number of doctree nodes can be reduced by \"normalizing\" some related\nnodes. This makes the document model and the writers somewhat simpler.\n\n* The \"doctest\" element can be replaced by literal blocks with a class\n  attribute (similar to the \"code\" directive output).\n  The syntax shall be left in reST.\n\n  [DG 2017-01-02:] +0.\n\n  Discussion\n    The syntax could be left in reST (for a set period of time?).\n\n    [DG 2017-01-02:] The syntax must be left in reST, practically\n    forever. Removing it would introduce a huge backwards\n    incompatibility. Any syntax removal must be preceded by a thorough\n    review and planning, including a deprecation warning process. My\n    opinion: it's not worth it.\n\n* \"Normalize\" special admonitions (note, hint, warning, ...) during parsing\n  (similar to _`transforms.writer_aux.Admonitions`). There is no need to\n  keep them as distinct elements in the doctree specification.\n\n  [DG 2017-01-02:] -1: <note>{body}</> is much more concise and\n  expressive than <admonition><title>Note</>{body}</>, and the title\n  translation can be put off until much later in the process.\n\n  [GM 2017-02-04]:\n\n  -0 for <admonition class=note><title>Note</>... instead of <note>:\n     a document is rarely printed/used as doctree or XML.\n\n  +1 reduce the complexity of the doctree\n     (there is no 1:1 rST syntax element <-> doctree node mapping anyway).\n\n  +2 every writer needs 9 visit_*/depart_* method pairs to handle the 9\n     subtypes of an admonition, i.e. we could but also remove 36 redundant\n     methods (HTML, LaTeX, Manpage, ODF).\n\n  -1 the most unfortunately named of these directives will survive.

There may be:\n\n  * duplicate reference and/or substitution names that need to be made\n    unique; and/or\n  * duplicate footnote numbers that need to be renumbered.\n\n  Should this be done before or after reference-resolving transforms\n  are applied?  What about references from within one subdocument to\n  inside another?\n\n* _`Document Splitting`\n\n  If the processed document is written to multiple files (possibly in\n  a directory tree), it will need to be split up.  Internal references\n  will have to be adjusted.\n\n  (HTML only?  Initially, yes.  Eventually, anything should be\n  splittable.)\n\n  Ideas:\n\n  - Insert a \"destination\" attribute into the root element of each\n    split-out document, containing the path/filename.  The Output\n    object or Writer will recognize this attribute and split out the\n    files accordingly.  Must allow for common headers & footers,\n    prev/next, breadcrumbs, etc.\n\n  - Transform a single-root document into a document containing\n    multiple subdocuments, recursively.  The content model of the\n    \"document\" element would have to change to::\n\n        <!ELEMENT document\n            ( (title, subtitle?)?,\n              decoration?,\n              (docinfo, transition?)?,\n              %structure.model;,\n              document* )>\n\n    (I.e., add the last line -- 0 or more document elements.)\n\n    Let's look at the case of hierarchical (directories and files)\n    HTML output.  Each document element containing further document\n    elements would correspond to a directory (with an index.html file\n    for the content preceding the subdocuments).  Each document\n    element containing no subdocuments (i.e., structure model elements\n    only) corresponds to a concrete file with no directory.\n\n    The natural transform would be to map sections to subdocuments,\n    but possibly only a given number of levels deep.\n\n* _`Navigation`\n\n  If a document is split up, each segment will need navigation links:\n  parent, children (small TOC), previous (preorder), next (preorder).\n  Part of `Document Splitting`_?\n\n* _`List of System Messages`\n\n  The ``system_message`` elements are inserted into the document tree,\n  adjacent to the problems themselves where possible.  Some (those\n  generated post-parse) are kept until later, in\n  ``document.messages``, and added as a special final section,\n  \"Docutils System Messages\".\n\n  Docutils could be made to generate hyperlinks to all known\n  system_messages and add them to the document, perhaps to the end of\n  the \"Docutils System Messages\" section.\n\n  Fred L. Drake, Jr. wrote:\n\n      I'd like to propose that both parse- and transformation-time\n      messages are included in the \"Docutils System Messages\" section.\n      If there are no objections, I can make the change.\n\n  The advantage of the current way of doing things is that parse-time\n  system messages don't require a transform; they're already in the\n  document.  This is valuable for testing (unit tests,\n  tools/quicktest.py).  So if we do decide to make a change, I think\n  the insertion of parse-time system messages ought to remain as-is\n  and the Messages transform ought to move all parse-time system\n  messages (remove from their originally inserted positions, insert in\n  System Messages section).\n\n* _`Index Generation`\n\n\nHTML Writer\n===========\n\n* Make the _`list compacting` logic more generic: For example, allow\n  for literal blocks or line blocks inside of compact list items.\n\n  This is not implementable as long as list compacting is done by\n  omitting ``<p>`` tags.  List compacting would need to be done by\n  adjusting CSS margins instead.\n\n  :2015-04-02: The new html writer no longer strips <p> tags but adds the\n               class value ``simple`` to the list.\n               Formatting is done by CSS --- configurable by a custom style\n               sheet.\n\n               Auto-compactization can be overridden by the ``open`` vs.\n               ``compact`` class arguments.\n\n* Idea for field-list rendering: hanging indent::\n\n      Field name (bold): First paragraph of field body begins\n          with the field name inline.\n\n          If the first item of a field body is not a paragraph,\n          it would begin on the following line.\n\n  :2015-04-02: The new html writer writes field-lists as definition lists\n               with class ``field-list``.\n               Formatting is done by CSS --- configurable by a custom style\n               sheet. The default style sheet has some examples, including a\n               run-in field-list style.\n\n* Add more support for <link> elements, especially for navigation\n  bars.\n\n  The framework does not have a notion of document relationships, so\n  probably raw.destination_ should be used.\n\n  We'll have framework support for document relationships when support\n  for `multiple output files`_ is added.  The HTML writer could\n  automatically generate <link> elements then.\n\n  .. _raw.destination: misc.raw_\n\n* Base list compaction on the spacing of source list?  Would require\n  parser support.  (Idea: fantasai, 16 Dec 2002, doc-sig.)\n\n* Add a tool tip (\"title\" attribute?) to footnote back-links\n  identifying them as such.  Text in Docutils language module.\n\n\nPEP/HTML Writer\n===============\n\n* Remove the generic style information (duplicated from html4css1.css)\n  from pep.css to avoid redundancy.\n\n  Set ``stylesheet-path`` to \"html4css.css,pep.css\" and the\n  ``stylesheet-dirs`` accordingly instead. (See the xhtml11 writer for an\n  example.)\n\n\nS5/HTML Writer\n==============\n\n* Add a way to begin an untitled slide.\n\n* Add a way to begin a new slide, continuation, using the same title\n  as the previous slide?  (Unnecessary?)  You need that if you have a\n  lot of items in one section which don't fit on one slide.\n\n  Maybe either this item or the previous one can be realized using\n  transitions.\n\n* Have a timeout on incremental items, so the colour goes away after 1\n  second.\n\n* Add an empty, black last slide (optionally).  Currently the handling\n  of the last slide is not very nice, it re-cycles through the\n  incremental items on the last slide if you hit space-bar after the\n  last item.\n\n* Add a command-line option to disable advance-on-click.\n\n* Add a speaker's master document, which would contain a small version\n  of the slide text with speaker's notes interspersed.  The master\n  document could use ``target=\"whatever\"`` to direct links to a\n  separate window on a second monitor (e.g., a projector).\n\n  .. Note:: This item and the following items are partially\n     accomplished by the S5 1.2 code (currently in alpha), which has\n     not yet been integrated into Docutils.\n\n* Speaker's notes -- how to intersperse?  Could use reST comments\n  (\"..\"), but make them visible in the speaker's master document.  If\n  structure is necessary, we could use a \"comment\" directive (to avoid\n  nonsensical DTD changes, the \"comment\" directive could produce an\n  untitled topic element).\n\n  The speaker's notes could (should?) be separate from S5's handout\n  content.\n\n* The speaker's master document could use frames for easy navigation:\n  TOC on the left, content on the right.\n\n  - It would be nice if clicking in the TOC frame simultaneously\n    linked to both the speaker's notes frame and to the slide window,\n    synchronizing both.  Needs JavaScript?\n\n  - TOC would have to be tightly formatted -- minimal indentation.\n\n  - TOC auto-generated, as in the PEP Reader.  (What if there already\n    is a \"contents\" directive in the document?)\n\n  - There could be another frame on the left (top-left or bottom-left)\n    containing a single \"Next\" link, always pointing to the next slide\n    (synchronized, of course).  Also \"Previous\" link?  FF/Rew go to\n    the beginning of the next/current parent section?  First/Last\n    also?  Tape-player-style buttons like ``|<<  <<  <  >  >>  >>|``?\n\nEpub/HTML Writer\n================\n\nAdd epub as an output format.\n\n  epub is an open file format for ebooks based on HTML, specified by the\n  `International Digital Publishing Forum`_.

All that's required is to choose components\nand supply settings for variations.  Let's take a look at a typical\ncommand-line front-end tool, ``tools/rst2html.py``, from top to\nbottom.\n\nOn Unixish systems, it's best to make the file executable (``chmod +x\nfile``), and supply an interpreter on the first line, the \"shebang\" or\n\"hash-bang\" line::\n\n    #!/usr/bin/env python\n\nWindows systems can be set up to associate the Python interpreter with\nthe ``.py`` extension.\n\nNext are some comments providing metadata::\n\n    # $Id$\n    # Author: David Goodger <goodger@python.org>\n    # Copyright: This module has been placed in the public domain.\n\nThe module docstring describes the purpose of the tool::\n\n    \"\"\"\n    A minimal front end to the Docutils Publisher, producing HTML.\n    \"\"\"\n\nThis next block attempts to invoke locale support for\ninternationalization services, specifically text encoding.

' + default_description)\n\nNow we call the Publisher convenience function, which takes over.\nMost of its defaults are used (\"standalone\" Reader,\n\"reStructuredText\" Parser, etc.).  The HTML Writer is chosen by name,\nand a description for command-line help is passed in::\n\n    publish_cmdline(writer_name='html', description=description)\n\nThat's it!  `The Docutils Publisher`_ takes care of the rest.\n\n.. _The Docutils Publisher: ./publisher.html\n"

Use the front-end\ncommand (``rst2html.py`` or ``rst2html5.py``) with the\n``--help`` option and look at the description of the ``--stylesheet-path``\ncommand-line option for the exact machine-specific location.\n\nTo customize the look of HTML documents, you can override the settings\nof the default stylesheet in your own stylesheet. Specify both, the\ndefault stylesheet and your stylesheet to the ``--stylesheet`` or\n``--stylesheet-path`` command line option (or the corresponding\nsettings in a configuration_ file), e.g. ::\n\n  rst2html.py --stylesheet=html4css1.css,transition-stars.css\n\nThis is the preferable approach if you want to embed the stylesheet(s), as\nthis ensures that an up-to-date version of ``html4css1.css`` is embedded.\n\nAlternatively, copy the default style sheet to the same place as your\noutput HTML files will go and place a new file (e.g. called\n``my-docutils.css``) in the same directory and use the following\ntemplate::\n\n    /*\n    :Author: Your Name\n    :Contact: Your Email Address\n    :Copyright: This stylesheet has been placed in the public domain.\n\n    Stylesheet for use with Docutils.  [Optionally place a more\n    detailed description here.]\n    */\n\n    @import url(html4css1.css);\n\n    /* Your customizations go here.  For example: */\n\n    h1, h2, h3, h4, h5, h6, p.topic-title {\n      font-family: sans-serif }\n\nFor help on the CSS syntax, see, e.g., the `W3C Specification`_, the\n`WDG's guide to Cascading Style Sheets`__, or the `MDN Web Docs`__.\n\n.. _W3C Specification: https://www.w3.org/Style/CSS/#specs\n__ http://www.htmlhelp.com/reference/css/\n__ https://developer.mozilla.org/en-US/docs/Web/CSS\n\nIt is important that you do not edit a copy of ``html4css1.css``\ndirectly because ``html4css1.css`` is frequently updated with each new\nrelease of Docutils.\n\nAlso make sure that you import ``html4css1.css`` (using \"``@import\nurl(html4css1.css);``\") because the definitions contained in the\ndefault stylesheet are required for correct rendering (margins,\nalignment, etc.).\n\nIf you think your stylesheet is fancy and you would like to let others\nbenefit from your efforts, you are encouraged to post the stylesheet to the\nDocutils-users_ mailing list. It might find its place in the `stylesheet\ncollection`_ in the Docutils Sandbox_.\n\nIf you decide to share your stylesheet with other users of Docutils,\nplease keep website-specific customizations not applicable to\nDocutils' HTML code in a separate stylesheet.\n\n.. base for relative links is /docutils/docs/howto/\n\n.. _Docutils-users: ../user/mailing-lists.html#docutils-users\n.. _configuration: ../user/config.txt\n.. _sandbox: ../../../sandbox\n.. _stylesheet collection: ../../../sandbox/stylesheets/\n\n\n\f\n..\n   Local Variables:\n   mode: indented-text\n   indent-tabs-mode: nil\n   sentence-end-double-space: t\n   fill-column: 70\n   End:\n"

Note::\n\n   The i18n facilities of Docutils should be considered a \"first\n   draft\".  They work so far, but improvements are welcome.\n   Specifically, standard i18n facilities like \"gettext\" have yet to\n   be explored.\n\nDocutils is designed to work flexibly with text in multiple languages\n(one language at a time).  Language-specific features are (or should\nbe [#]_) fully parameterized.  To enable a new language, two modules\nhave to be added to the project: one for Docutils itself (the\n`Docutils Language Module`_) and one for the reStructuredText parser\n(the `reStructuredText Language Module`_). Users may add local language\nsupport via a module in the PYTHONPATH root (e.g. the working directory).\n\n.. [#] If anything in Docutils is insufficiently parameterized, it\n   should be considered a bug.  Please report bugs to the Docutils\n   project bug tracker on SourceForge at\n   https://sourceforge.net/p/docutils/bugs/\n\n.. _Docutils: https://docutils.sourceforge.io/\n.. _Introduction to i18n:\n   http://www.debian.org/doc/manuals/intro-i18n/\n\n\nLanguage Module Names\n=====================\n\nLanguage modules are named using `language tags`_ as defined in\n`BCP 47`_. [#]_ in lowercase, converting hyphens to underscores [#]_.\n\nA typical language identifier consists of a 2-letter language code\nfrom `ISO 639`_ (3-letter codes can be used if no 2-letter code\nexists). The language identifier can have an optional subtag,\ntypically for variations based on country (from `ISO 3166`_ 2-letter\ncountry codes).  If no language identifier is specified, the default\nis \"en\" for English.  Examples of module names include ``en.py``,\n``fr.py``, ``ja.py``, and ``pt_br.py``.\n\n.. [#] BCP stands for 'Best Current Practice', and is a persistent\n   name for a series of RFCs whose numbers change as they are updated.\n   The latest RFC describing language tag syntax is RFC 5646, Tags for\n   the Identification of Languages, and it obsoletes the older RFCs\n   4646, 3066 and 1766.\n\n.. [#] Subtags are separated from primary tags by underscores instead\n   of hyphens, to conform to Python naming rules.\n\n.. _language tags: https://www.w3.org/International/articles/language-tags/\n.. _BCP 47: https://www.rfc-editor.org/rfc/bcp/bcp47.txt\n.. _ISO 639: http://www.loc.gov/standards/iso639-2/php/English_list.php\n.. _ISO 3166: http://www.iso.ch/iso/en/prods-services/iso3166ma/\n   02iso-3166-code-lists/index.html\n\n\nDocutils Language Module\n========================\n\nModules in ``docutils/languages`` contain language mappings for\nmarkup-independent language-specific features of Docutils.  To make a\nnew language module, just copy the ``en.py`` file, rename it with the\ncode for your language (see `Language Module Names`_ above), and\ntranslate the terms as described below.\n\nEach Docutils language module contains three module attributes:\n\n``labels``\n    This is a mapping of node class names to language-dependent\n    boilerplate label text.  The label text is used by Writer\n    components when they encounter document tree elements whose class\n    names are the mapping keys.\n\n    The entry values (*not* the keys) should be translated to the\n    target language.\n\n``bibliographic_fields``\n    This is a mapping of language-dependent field names (converted to\n    lower case) to canonical field names (keys of\n    ``DocInfo.biblio_notes`` in ``docutils.transforms.frontmatter``).\n    It is used when transforming bibliographic fields.\n\n    The keys should be translated to the target language.\n\n``author_separators``\n    This is a list of strings used to parse the 'Authors'\n    bibliographic field.  They separate individual authors' names, and\n    are tried in order (i.e., earlier items take priority, and the\n    first item that matches wins).  The English-language module\n    defines them as ``[';', ',']``; semi-colons can be used to\n    separate names like \"Arthur Pewtie, Esq.\".\n\n    Most languages won't have to \"translate\" this list.\n\n\nreStructuredText Language Module\n================================\n\nModules in ``docutils/parsers/rst/languages`` contain language\nmappings for language-specific features of the reStructuredText\nparser.  To make a new language module, just copy the ``en.py`` file,\nrename it with the code for your language (see `Language Module\nNames`_ above), and translate the terms as described below.\n\nEach reStructuredText language module contains two module attributes:\n\n``directives``\n    This is a mapping from language-dependent directive names to\n    canonical directive names.  The canonical directive names are\n    registered in ``docutils/parsers/rst/directives/__init__.py``, in\n    ``_directive_registry``.\n\n    The keys should be translated to the target language.  Synonyms\n    (multiple keys with the same values) are allowed; this is useful\n    for abbreviations.\n\n``roles``\n    This is a mapping language-dependent role names to canonical role\n    names for interpreted text.  The canonical directive names are\n    registered in ``docutils/parsers/rst/states.py``, in\n    ``Inliner._interpreted_roles`` (this may change).\n\n    The keys should be translated to the target language.  Synonyms\n    (multiple keys with the same values) are allowed; this is useful\n    for abbreviations.\n\n\nTesting the Language Modules\n============================\n\nWhenever a new language module is added or an existing one modified,\nthe unit tests should be run.

    "content": "=======================================\n Creating reStructuredText_ Directives\n=======================================\n\n:Authors: Dethe Elza, David Goodger, Lea Wiemann\n:Contact: docutils-develop@lists.sourceforge.net\n:Date: $Date$\n:Revision: $Revision$\n:Copyright: This document has been placed in the public domain.\n\n.. _reStructuredText: https://docutils.sourceforge.io/rst.html\n\n\nDirectives are the primary extension mechanism of reStructuredText.\nThis document aims to make the creation of new directives as easy and\nunderstandable as possible.  There are only a couple of\nreStructuredText-specific features the developer needs to know to\ncreate a basic directive.\n\nThe syntax of directives is detailed in the `reStructuredText Markup\nSpecification`_, and standard directives are described in\n`reStructuredText Directives`_.\n\nDirectives are a reStructuredText markup/parser concept.  There is no\n\"directive\" document tree element, no single element that corresponds\nexactly to the concept of directives.  Instead, choose the most\nappropriate elements from the existing Docutils elements.  Directives\nbuild structures using the existing building blocks.  See `The\nDocutils Document Tree`_ and the ``docutils.nodes`` module for more\nabout the building blocks of Docutils documents.\n\n.. _reStructuredText Markup Specification:\n   ../ref/rst/restructuredtext.html#directives\n.. _reStructuredText Directives: ../ref/rst/directives.html\n.. _The Docutils Document Tree: ../ref/doctree.html\n\n\n.. contents:: Table of Contents\n\n\nThe Directive Class\n===================\n\nDirectives are created by defining a directive class that inherits\nfrom ``docutils.parsers.rst.Directive``::\n\n    from docutils.parsers import rst\n\n    class MyDirective(rst.Directive):\n\n        ...\n\nTo understand how to implement the directive, let's have a look at the\ndocstring of the ``Directive`` base class::\n\n    >>> from docutils.parsers import rst\n    >>> print rst.Directive.__doc__\n\n        Base class for reStructuredText directives.\n\n        The following attributes may be set by subclasses.  They are\n        interpreted by the directive parser (which runs the directive\n        class):\n\n        - `required_arguments`: The number of required arguments (default:\n          0).\n\n        - `optional_arguments`: The number of optional arguments (default:\n          0).\n\n        - `final_argument_whitespace`: A boolean, indicating if the final\n          argument may contain whitespace (default: False).\n\n        - `option_spec`: A dictionary, mapping known option names to\n          conversion functions such as `int` or `float` (default: {}, no\n          options).  Several conversion functions are defined in the\n          directives/__init__.py module.\n\n          Option conversion functions take a single parameter, the option\n          argument (a string or ``None``), validate it and/or convert it\n          to the appropriate form.  Conversion functions may raise\n          `ValueError` and `TypeError` exceptions.\n\n        - `has_content`: A boolean; True if content is allowed.  Client\n          code must handle the case where content is required but not\n          supplied (an empty content list will be supplied).\n\n        Arguments are normally single whitespace-separated words.  The\n        final argument may contain whitespace and/or newlines if\n        `final_argument_whitespace` is True.\n\n        If the form of the arguments is more complex, specify only one\n        argument (either required or optional) and set\n        `final_argument_whitespace` to True; the client code must do any\n        context-sensitive parsing.\n\n        When a directive implementation is being run, the directive class\n        is instantiated, and the `run()` method is executed.  During\n        instantiation, the following instance variables are set:\n\n        - ``name`` is the directive type or name (string).\n\n        - ``arguments`` is the list of positional arguments (strings).\n\n        - ``options`` is a dictionary mapping option names (strings) to\n          values (type depends on option conversion functions; see\n          `option_spec` above).\n\n        - ``content`` is a list of strings, the directive content line by line.\n\n        - ``lineno`` is the line number of the first line of the directive.\n\n        - ``content_offset`` is the line offset of the first line of the content from\n          the beginning of the current input.  Used when initiating a nested parse.\n\n        - ``block_text`` is a string containing the entire directive.\n\n        - ``state`` is the state which called the directive function.\n\n        - ``state_machine`` is the state machine which controls the state which called\n          the directive function.\n\n        Directive functions return a list of nodes which will be inserted\n        into the document tree at the point where the directive was\n        encountered.  This can be an empty list if there is nothing to\n        insert.\n\n        For ordinary directives, the list must contain body elements or\n        structural elements.  Some directives are intended specifically\n        for substitution definitions, and must return a list of `Text`\n        nodes and/or inline elements (suitable for inline insertion, in\n        place of the substitution reference).  Such directives must verify\n        substitution definition context, typically using code like this::\n\n            if not isinstance(state, states.SubstitutionDef):\n                error = state_machine.reporter.error(\n                    'Invalid context: the \"%s\" directive can only be used '\n                    'within a substitution definition.' % (name),\n                    nodes.literal_block(block_text, block_text), line=lineno)\n                return [error]\n\n    >>>\n\n\nOption Conversion Functions\n===========================\n\nAn option specification (``Directive.option_spec``) must be defined\ndetailing the options available to the directive.  An option spec is a\nmapping of option name to conversion function; conversion functions\nare applied to each option value to check validity and convert them to\nthe expected type.  Python's built-in conversion functions are often\nusable for this, such as ``int``, ``float``.  Other useful conversion\nfunctions are included in the ``docutils.parsers.rst.directives``\npackage (in the ``__init__.py`` module):\n\n- ``flag``: For options with no option arguments.  Checks for an\n  argument (raises ``ValueError`` if found), returns ``None`` for\n  valid flag options.\n\n- ``unchanged_required``: Returns the text argument, unchanged.\n  Raises ``ValueError`` if no argument is found.\n\n- ``unchanged``: Returns the text argument, unchanged.  Returns an\n  empty string (\"\") if no argument is found.\n\n- ``path``: Returns the path argument unwrapped (with newlines\n  removed).  Raises ``ValueError`` if no argument is found.\n\n- ``uri``: Returns the URI argument with whitespace removed.  Raises\n  ``ValueError`` if no argument is found.\n\n- ``nonnegative_int``: Checks for a nonnegative integer argument,\n  and raises ``ValueError`` if not.\n\n- ``class_option``: Converts the argument into an ID-compatible\n  string and returns it.  Raises ``ValueError`` if no argument is\n  found.\n\n- ``unicode_code``: Convert a Unicode character code to a Unicode\n  character.\n\n- ``single_char_or_unicode``: A single character is returned as-is.\n  Unicode characters codes are converted as in ``unicode_code``.\n\n- ``single_char_or_whitespace_or_unicode``: As with\n  ``single_char_or_unicode``, but \"tab\" and \"space\" are also\n  supported.\n\n- ``positive_int``: Converts the argument into an integer.  Raises\n  ValueError for negative, zero, or non-integer values.\n\n- ``positive_int_list``: Converts a space- or comma-separated list\n  of integers into a Python list of integers.  Raises ValueError for\n  non-positive-integer values.\n\n- ``encoding``: Verifies the encoding argument by lookup.  Raises\n  ValueError for unknown encodings.\n\nA further utility function, ``choice``, is supplied to enable\noptions whose argument must be a member of a finite set of possible\nvalues.  A custom conversion function must be written to use it.\nFor example::\n\n    from docutils.parsers.rst import directives\n\n    def yesno(argument):\n        return directives.choice(argument, ('yes', 'no'))\n\nFor example, here is an option spec for a directive which allows two\noptions, \"name\" and \"value\", each with an option argument::\n\n    option_spec = {'name': unchanged, 'value': int}\n\n\nError Handling\n==============\n\nIf your directive implementation encounters an error during\nprocessing, you should call ``self.error()`` inside the ``run()``\nmethod::\n\n    if error_condition:\n        raise self.error('Error message.')\n\nThe ``self.error()`` method will immediately raise an exception that\nwill be caught by the reStructuredText directive handler.  The\ndirective handler will then insert an error-level system message in\nthe document at the place where the directive occurred.\n\nInstead of ``self.error``, you can also use ``self.severe`` and\n``self.warning`` for more or less severe problems.\n\nIf you want to return a system message *and* document contents, you need to\ncreate the system message yourself instead of using the ``self.error``\nconvenience method::\n\n    def run(self):\n        # Create node(s).\n        node = nodes.paragraph(...)\n        # Node list to return.\n        node_list = [node]\n        if error_condition:\n             # Create system message.\n             error = self.reporter.error(\n                 'Error in \"%s\" directive: Your error message.' % self.name,\n                 nodes.literal_block(block_text, block_text), line=lineno)\n             node_list.append(error)\n        return node_list\n\n\nRegister the Directive\n======================\n\n* If the directive is a general-use **addition to the Docutils core**,\n  it must be registered with the parser and language mappings added:\n\n  1. Register the new directive using its canonical name in\n     ``docutils/parsers/rst/directives/__init__.py``, in the\n     ``_directive_registry`` dictionary.  This allows the\n     reStructuredText parser to find and use the directive.\n\n  2. Add an entry to the ``directives`` dictionary in\n     ``docutils/parsers/rst/languages/en.py`` for the directive, mapping\n     the English name to the canonical name (both lowercase).  Usually\n     the English name and the canonical name are the same.\n\n  3. Update all the other language modules as well.  For languages in\n     which you are proficient, please add translations.  For other\n     languages, add the English directive name plus \"(translation\n     required)\".\n\n* If the directive is **application-specific**, use the\n  ``register_directive`` function::\n\n      from docutils.parsers.rst import directives\n      directives.register_directive(directive_name, directive_class)\n\n\nExamples\n========\n\nFor the most direct and accurate information, \"Use the Source, Luke!\".\nAll standard directives are documented in `reStructuredText\nDirectives`_, and the source code implementing them is located in the\n``docutils/parsers/rst/directives`` package.  The ``__init__.py``\nmodule contains a mapping of directive name to module and function\nname.  Several representative directives are described below.\n\n\nAdmonitions\n-----------\n\n`Admonition directives`__, such as \"note\" and \"caution\", are quite\nsimple.  They have no directive arguments or options.  Admonition\ndirective content is interpreted as ordinary reStructuredText.\n\n__ ../ref/rst/directives.html#specific-admonitions\n\nThe resulting document tree for a simple reStructuredText line\n\"``.. note:: This is a note.``\" looks as follows:\n\n    <note>\n        <paragraph>\n            This is a note.\n\nThe directive class for the \"note\" directive simply derives from a\ngeneric admonition directive class::\n\n    class Note(BaseAdmonition):\n\n        node_class = nodes.note\n\nNote that the only thing distinguishing the various admonition\ndirectives is the element (node class) generated.  In the code above,\nthe node class is set as a class attribute and is read by the\n``run()`` method of ``BaseAdmonition``, where the actual processing\ntakes place::\n\n    # Import Docutils document tree nodes module.\n    from docutils import nodes\n    # Import Directive base class.\n    from docutils.parsers.rst import Directive\n\n    class BaseAdmonition(Directive):\n\n        required_arguments = 0\n        optional_arguments = 0\n        final_argument_whitespace = True\n        option_spec = {}\n        has_content = True\n\n        node_class = None\n        \"\"\"Subclasses must set this to the appropriate admonition node class.\"\"\"\n\n        def run(self):\n            # Raise an error if the directive does not have contents.\n            self.assert_has_content()\n            text = '\\n'.join(self.content)\n            # Create the admonition node, to be populated by `nested_parse`.\n            admonition_node = self.node_class(rawsource=text)\n            # Parse the directive contents.\n            self.state.nested_parse(self.content, self.content_offset,\n                                    admonition_node)\n            return [admonition_node]\n\nThree things are noteworthy in the ``run()`` method above:\n\n* The ``admonition_node = self.node_class(text)`` line creates the\n  wrapper element, using the class set by the specific admonition\n  subclasses (as in note, ``node_class = nodes.note``).\n\n* The call to ``state.nested_parse()`` is what does the actual\n  processing.  It parses the directive content and adds any generated\n  elements as child elements of ``admonition_node``.\n\n* If there was no directive content, the ``assert_has_content()``\n  convenience method raises an error exception by calling\n  ``self.error()`` (see `Error Handling`_ above).\n\n\n\"image\"\n-------\n\n.. _image: ../ref/rst/directives.html#image\n\nThe \"image_\" directive is used to insert a picture into a document.\nThis directive has one argument, the path to the image file, and\nsupports several options.  There is no directive content.  Here's an\nearly version of the image directive class::\n\n    # Import Docutils document tree nodes module.\n    from docutils import nodes\n    # Import ``directives`` module (contains conversion functions).\n    from docutils.parsers.rst import directives\n    # Import Directive base class.\n    from docutils.parsers.rst import Directive\n\n    def align(argument):\n        \"\"\"Conversion function for the \"align\" option.\"\"\"\n        return directives.choice(argument, ('left', 'center', 'right'))\n\n    class Image(Directive):\n\n        required_arguments = 1\n        optional_arguments = 0\n        final_argument_whitespace = True\n        option_spec = {'alt': directives.unchanged,\n                       'height': directives.nonnegative_int,\n                       'width': directives.nonnegative_int,\n                       'scale': directives.nonnegative_int,\n                       'align': align,\n                       }\n        has_content = False\n\n        def run(self):\n            reference = directives.uri(self.arguments[0])\n            self.options['uri'] = reference\n            image_node = nodes.image(rawsource=self.block_text,\n                                     **self.options)\n            return [image_node]\n\nSeveral things are noteworthy in the code above:\n\n* The \"image\" directive requires a single argument, which is allowed\n  to contain whitespace (``final_argument_whitespace = True``).  This\n  is to allow for long URLs which may span multiple lines.  The first\n  line of the ``run()`` method joins the URL, discarding any embedded\n  whitespace.\n\n* The reference is added to the ``options`` dictionary under the\n  \"uri\" key; this becomes an attribute of the ``nodes.image`` element\n  object.  Any other attributes have already been set explicitly in\n  the reStructuredText source text.\n\n\nThe Pending Element\n-------------------\n\nDirectives that cause actions to be performed *after* the complete\ndocument tree has been generated can be implemented using a\n``pending`` node.  The ``pending`` node causes a transform_ to be run\nafter the document has been parsed.\n\nFor an example usage of the ``pending`` node, see the implementation\nof the ``contents`` directive in\ndocutils.parsers.rst.directives.parts__.\n\n.. _transform: ../api/transforms.html\n__ https://docutils.sourceforge.io/docutils/parsers/rst/directives/parts.py\n"

Its signature is as follows::\n\n    def role_fn(name, rawtext, text, lineno, inliner,\n                options=None, content=None):\n        code...\n\n    # Optional function attributes for customization:\n    role_fn.options = ...\n    role_fn.content = ...\n\nFunction attributes are described below (see `Specify Role Function\nOptions and Content`_).  The role function parameters are as follows:\n\n* ``name``: The local name of the interpreted role, the role name\n  actually used in the document.\n\n* ``rawtext``: A string containing the entire interpreted text input,\n  including the role and markup.  Return it as a ``problematic`` node\n  linked to a system message if a problem is encountered.\n\n* ``text``: The interpreted text content.\n\n* ``lineno``: The line number where the text block containing the\n  interpreted text begins.\n\n* ``inliner``: The ``docutils.parsers.rst.states.Inliner`` object that\n  called role_fn.  It contains the several attributes useful for error\n  reporting and document tree access.\n\n* ``options``: A dictionary of directive options for customization\n  (from the `\"role\" directive`_), to be interpreted by the role\n  function.  Used for additional attributes for the generated elements\n  and other functionality.\n\n* ``content``: A list of strings, the directive content for\n  customization (from the `\"role\" directive`_).  To be interpreted by\n  the role function.\n\nRole functions return a tuple of two values:\n\n* A list of nodes which will be inserted into the document tree at the\n  point where the interpreted role was encountered (can be an empty\n  list).\n\n* A list of system messages, which will be inserted into the document tree\n  immediately after the end of the current block (can also be empty).\n\n\nSpecify Role Function Options and Content\n=========================================\n\nFunction attributes are for customization, and are interpreted by the\n`\"role\" directive`_.  If unspecified, role function attributes are\nassumed to have the value ``None``.  Two function attributes are\nrecognized:\n\n- ``options``: The option specification.  All role functions\n  implicitly support the \"class\" option, unless disabled with an\n  explicit ``{'class': None}``.\n\n  An option specification must be defined detailing the options\n  available to the \"role\" directive.  An option spec is a mapping of\n  option name to conversion function; conversion functions are applied\n  to each option value to check validity and convert them to the\n  expected type.  Python's built-in conversion functions are often\n  usable for this, such as ``int``, ``float``, and ``bool`` (included\n  in Python from version 2.2.1).  Other useful conversion functions\n  are included in the ``docutils.parsers.rst.directives`` package.\n  For further details, see `Creating reStructuredText Directives`_.\n\n- ``content``: A boolean; true if \"role\" directive content is allowed.\n  Role functions must handle the case where content is required but\n  not supplied (an empty content list will be supplied).\n\n  As of this writing, no roles accept directive content.\n\nNote that unlike directives, the \"arguments\" function attribute is not\nsupported for role customization.  Directive arguments are handled by\nthe \"role\" directive itself.\n\n.. _\"role\" directive: ../ref/rst/directives.html#role\n.. _Creating reStructuredText Directives:\n   rst-directives.html#specify-directive-arguments-options-and-content\n\n\nRegister the Role\n=================\n\nIf the role is a general-use addition to the Docutils core, it must be\nregistered with the parser and language mappings added:\n\n1. Register the new role using the canonical name::\n\n       from docutils.parsers.rst import roles\n       roles.register_canonical_role(name, role_function)\n\n   This code is normally placed immediately after the definition of\n   the role function.\n\n2. Add an entry to the ``roles`` dictionary in\n   ``docutils/parsers/rst/languages/en.py`` for the role, mapping the\n   English name to the canonical name (both lowercase).  Usually the\n   English name and the canonical name are the same.  Abbreviations\n   and other aliases may also be added here.\n\n3. Update all the other language modules as well.  For languages in\n   which you are proficient, please add translations.  For other\n   languages, add the English role name plus \"(translation required)\".\n\nIf the role is application-specific, use the ``register_local_role``\nfunction::\n\n    from docutils.parsers.rst import roles\n    roles.register_local_role(name, role_function)\n\n\nExamples\n========\n\nFor the most direct and accurate information, \"Use the Source, Luke!\".\nAll standard roles are documented in `reStructuredText Interpreted\nText Roles`_, and the source code implementing them is located in the\n``docutils/parsers/rst/roles.py`` module.  Several representative\nroles are described below.\n\n\nGeneric Roles\n-------------\n\nMany roles simply wrap a given element around the text.  There's a\nspecial helper function, ``register_generic_role``, which generates a\nrole function from the canonical role name and node class::\n\n    register_generic_role('emphasis', nodes.emphasis)\n\nFor the implementation of ``register_generic_role``, see the\n``docutils.parsers.rst.roles`` module.\n\n\nRFC Reference Role\n------------------\n\nThis role allows easy references to RFCs_ (Request For Comments\ndocuments) by automatically providing the base URL,\nhttp://www.faqs.org/rfcs/, and appending the RFC document itself\n(rfcXXXX.html, where XXXX is the RFC number).  For example::\n\n    See :RFC:`2822` for information about email headers.\n\nThis is equivalent to::\n\n    See `RFC 2822`__ for information about email headers.\n\n    __ http://www.faqs.org/rfcs/rfc2822.html\n\nHere is the implementation of the role::\n\n    def rfc_reference_role(role, rawtext, text, lineno, inliner,\n                           options=None, content=None):\n        if \"#\" in text:\n            rfcnum, section = utils.unescape(text).split(\"#\", 1)\n        else:\n            rfcnum, section  = utils.unescape(text), None\n        try:\n            rfcnum = int(rfcnum)\n            if rfcnum < 1:\n                raise ValueError\n        except ValueError:\n            msg = inliner.reporter.error(\n                'RFC number must be a number greater than or equal to 1; '\n                '\"%s\" is invalid.' % text, line=lineno)\n            prb = inliner.problematic(rawtext, rawtext, msg)\n            return [prb], [msg]\n        # Base URL mainly used by inliner.rfc_reference, so this is correct:\n        ref = inliner.document.settings.rfc_base_url + inliner.rfc_url % rfcnum\n        if section is not None:\n            ref += \"#\"+section\n        options = normalize_role_options(options)\n        node = nodes.reference(rawtext, 'RFC ' + str(rfcnum), refuri=ref,\n                               **options)\n        return [node], []\n\n    register_canonical_role('rfc-reference', rfc_reference_role)\n\nNoteworthy in the code above are:\n\n1. The interpreted text itself should contain the RFC number.  The\n   ``try`` clause verifies by converting it to an integer.  If the\n   conversion fails, the ``except`` clause is executed: a system\n   message is generated, the entire interpreted text construct (in\n   ``rawtext``) is wrapped in a ``problematic`` node (linked to the\n   system message), and the two are returned.\n\n2. The RFC reference itself is constructed from a stock URI, set as\n   the \"refuri\" attribute of a \"reference\" element.\n\n3. The ``options`` function parameter, a dictionary, may contain a\n   \"class\" customization attribute; it is interpreted and replaced\n   with a \"classes\" attribute by the ``set_classes()`` function.  The\n   resulting \"classes\" attribute is passed through to the \"reference\"\n   element node constructor.\n\n.. _RFCs: http://foldoc.doc.ic.ac.uk/foldoc/foldoc.cgi?query=rfc&action=Search&sourceid=Mozilla-search\n"

Through-the-web editing and processing was\nnot envisaged, therefore web security was not a consideration.  Once\nDocutils/reStructuredText started being incorporated into an\never-increasing number of web applications (blogs__, wikis__, content\nmanagement systems, and others), several security issues arose and\nhave been addressed.  Still, **Docutils does not come in a\nthrough-the-web secure state**, because this would inconvenience\nordinary users.  This document provides pointers to help you secure\nthe Docutils software in your applications.\n\n__ ../../FAQ.html#are-there-any-weblog-blog-projects-that-use-restructuredtext-syntax\n__ ../../FAQ.html#are-there-any-wikis-that-use-restructuredtext-syntax\n\n\nThe Issues\n==========\n\nFile Creation\n-------------\n\nDocutils does not do any checks before writing to a file:\n\n* Existing **files are overwritten** without asking!\n* Files may be **written to any location** accessible to the process.\n* There are **no restrictions to** the **file names**.\n\nSpecial care must be taken when allowing users to configure the *output\ndestination* or the `warning_stream`_, `record_dependencies`_, or\n`_destination`_ settings.\n\n.. _warning_stream: ../user/config.html#warning-stream\n.. _record_dependencies: ../user/config.html#record-dependencies\n.. _`_destination`: ../user/config.html#destination\n\n\nExternal Data Insertion\n-----------------------\n\nThere are several `reStructuredText directives`_ that can insert\nexternal data (files and URLs) into the output document.  These\ndirectives are:\n\n* \"include_\", by its very nature,\n* \"raw_\", through its ``:file:`` and ``:url:`` options,\n* \"csv-table_\", through its ``:file:`` and ``:url:`` options,\n* \"image_\", if `embed_images`_ is true.\n\nThe \"include_\" directive and the other directives' file insertion\nfeatures can be disabled by setting \"file_insertion_enabled_\" to\n\"false__\".\n\n__ ../user/config.html#configuration-file-syntax\n.. _reStructuredText directives: ../ref/rst/directives.html\n.. _include: ../ref/rst/directives.html#include\n.. _raw: ../ref/rst/directives.html#raw-directive\n.. _csv-table: ../ref/rst/directives.html#csv-table\n.. _image: ../ref/rst/directives.html#image\n.. _embed_images: ../user/config.html#embed-images\n.. _file_insertion_enabled: ../user/config.html#file-insertion-enabled\n\n\nRaw HTML Insertion\n------------------\n\nThe \"raw_\" directive is intended for the insertion of\nnon-reStructuredText data that is passed untouched to the Writer.\nThis directive can be abused to bypass site features or insert\nmalicious JavaScript code into a web page.  The \"raw_\" directive can\nbe disabled by setting \"raw_enabled_\" to \"false\".\n\n.. _raw_enabled: ../user/config.html#raw-enabled\n\n\nCPU and memory utilization\n--------------------------\n\nParsing **complex reStructuredText documents may require high\nprocessing resources**. This enables `Denial of Service` attacks using\nspecially crafted input.\n\nIt is recommended to enforce limits for the computation time and\nresource utilization of the Docutils process when processing\nuntrusted input. In addition, the \"line_length_limit_\" can be\nadapted.\n\n.. _line_length_limit: ../user/config.html#line-length-limit\n\n\nSecuring Docutils\n=================\n\nProgrammatically Via Application Default Settings\n-------------------------------------------------\n\nIf your application calls Docutils via one of the `convenience\nfunctions`_, you can pass a dictionary of default settings that\noverride the component defaults::\n\n    defaults = {'file_insertion_enabled': False,\n                'raw_enabled': False}\n    output = docutils.core.publish_string(\n        ..., settings_overrides=defaults)\n\nNote that these defaults can be overridden by configuration files (and\ncommand-line options if applicable).  If this is not desired, you can\ndisable configuration file processing with the ``_disable_config``\nsetting::\n\n    defaults = {'file_insertion_enabled': False,\n                'raw_enabled': False,\n                '_disable_config': True}\n    output = docutils.core.publish_string(\n        ..., settings_overrides=defaults)\n\n.. _convenience functions: ../api/publisher.html\n\n\nVia a Configuration File\n------------------------\n\nYou may secure Docutils via a configuration file:\n\n* if your application executes one of the `Docutils front-end tools`_\n  as a separate process;\n* if you cannot or choose not to alter the source code of your\n  application or the component that calls Docutils; or\n* if you want to secure all Docutils deployments system-wide.\n\nIf you call Docutils programmatically, it may be preferable to use the\nmethods described in the section above.\n\nDocutils automatically looks in three places for a configuration file:\n\n* ``/etc/docutils.conf``, for system-wide configuration,\n* ``./docutils.conf`` (in the current working directory), for\n  project-specific configuration, and\n* ``~/.docutils`` (in the user's home directory), for user-specific\n  configuration.\n\nThese locations can be overridden by the ``DOCUTILSCONFIG``\nenvironment variable.  Details about configuration files, the purpose\nof the various locations, and ``DOCUTILSCONFIG`` are available in the\n`\"Configuration Files\"`_ section of `Docutils Configuration`_.\n\nTo fully secure a recent Docutils installation, the configuration file\nshould contain the following lines ::\n\n    [general]\n    file-insertion-enabled: off\n    raw-enabled: no\n\nand untrusted users must be prevented to modify or create local\nconfiguration files that overwrite these settings.\n\n.. _Docutils front-end tools: ../user/tools.html\n.. _\"Configuration Files\": ../user/config.html#configuration-files\n.. _Docutils Configuration: ../user/config.html\n\n\nVersion Applicability\n=====================\n\nThe \"file_insertion_enabled_\" and \"raw_enabled_\" settings were added\nto Docutils 0.3.9; previous versions will ignore these settings.\n\nA bug existed in the configuration file handling of these settings in\nDocutils 0.4 and earlier: the right-hand-side needed to be left blank\n(no values)::\n\n       [general]\n       file-insertion-enabled:\n       raw-enabled:\n\nThe bug was fixed with the 0.4.1 release on 2006-11-12.\n\nThe \"line_length_limit_\" is new in Docutils 0.17.\n\n\nRelated Documents\n=================\n\n`Docutils Runtime Settings`_ explains the relationship between\ncomponent settings specifications, application settings\nspecifications, configuration files, and command-line options\n\n`Docutils Configuration`_ describes configuration files (locations,\nstructure, and syntax), and lists all settings and command-line\noptions.\n\n.. _Docutils Runtime Settings: ../api/runtime-settings.html\n"

    "content": "PEP: 256\nTitle: Docstring Processing System Framework\nVersion: $Revision$\nLast-Modified: $Date$\nAuthor: David Goodger <goodger@python.org>\nDiscussions-To: <doc-sig@python.org>\nStatus: Rejected\nType: Standards Track\nContent-Type: text/x-rst\nCreated: 01-Jun-2001\nPost-History: 13-Jun-2001\n\n\nRejection Notice\n================\n\nThis proposal seems to have run out of steam.\n\n\nAbstract\n========\n\nPython lends itself to inline documentation.  With its built-in\ndocstring syntax, a limited form of `Literate Programming`_ is easy to\ndo in Python.  However, there are no satisfactory standard tools for\nextracting and processing Python docstrings.  The lack of a standard\ntoolset is a significant gap in Python's infrastructure; this PEP aims\nto fill the gap.\n\nThe issues surrounding docstring processing have been contentious and\ndifficult to resolve.  This PEP proposes a generic Docstring\nProcessing System (DPS) framework, which separates out the components\n(program and conceptual), enabling the resolution of individual issues\neither through consensus (one solution) or through divergence (many).\nIt promotes standard interfaces which will allow a variety of plug-in\ncomponents (input context readers, markup parsers, and output format\nwriters) to be used.\n\nThe concepts of a DPS framework are presented independently of\nimplementation details.\n\n\nRoad Map to the Docstring PEPs\n==============================\n\nThere are many aspects to docstring processing.  The \"Docstring PEPs\"\nhave broken up the issues in order to deal with each of them in\nisolation, or as close as possible.  The individual aspects and\nassociated PEPs are as follows:\n\n* Docstring syntax.  PEP 287, \"reStructuredText Docstring Format\"\n  [#PEP-287]_, proposes a syntax for Python docstrings, PEPs, and\n  other uses.\n\n* Docstring semantics consist of at least two aspects:\n\n  - Conventions: the high-level structure of docstrings.  Dealt with\n    in PEP 257, \"Docstring Conventions\" [#PEP-257]_.\n\n  - Methodology: rules for the informational content of docstrings.\n    Not addressed.\n\n* Processing mechanisms.  This PEP (PEP 256) outlines the high-level\n  issues and specification of an abstract docstring processing system\n  (DPS).  PEP 258, \"Docutils Design Specification\" [#PEP-258]_, is an\n  overview of the design and implementation of one DPS under\n  development.\n\n* Output styles: developers want the documentation generated from\n  their source code to look good, and there are many different ideas\n  about what that means.  PEP 258 touches on \"Stylist Transforms\".\n  This aspect of docstring processing has yet to be fully explored.\n\nBy separating out the issues, we can form consensus more easily\n(smaller fights ;-), and accept divergence more readily.\n\n\nRationale\n=========\n\nThere are standard inline documentation systems for some other\nlanguages.  For example, Perl has POD_ (\"Plain Old Documentation\") and\nJava has Javadoc_, but neither of these mesh with the Pythonic way.\nPOD syntax is very explicit, but takes after Perl in terms of\nreadability.  Javadoc is HTML-centric; except for \"``@field``\" tags,\nraw HTML is used for markup.  There are also general tools such as\nAutoduck_ and Web_ (Tangle & Weave), useful for multiple languages.\n\nThere have been many attempts to write auto-documentation systems\nfor Python (not an exhaustive list):\n\n- Marc-Andre Lemburg's doc.py_\n\n- Daniel Larsson's pythondoc_ & gendoc_\n\n- Doug Hellmann's HappyDoc_\n\n- Laurence Tratt's Crystal (no longer available on the web)\n\n- Ka-Ping Yee's pydoc_ (pydoc.py is now part of the Python standard\n  library; see below)\n\n- Tony Ibbs' docutils_ (Tony has donated this name to the `Docutils\n  project`_)\n\n- Edward Loper's STminus_ formalization and related efforts\n\nThese systems, each with different goals, have had varying degrees of\nsuccess.  A problem with many of the above systems was over-ambition\ncombined with inflexibility.  They provided a self-contained set of\ncomponents: a docstring extraction system, a markup parser, an\ninternal processing system and one or more output format writers with\na fixed style.  Inevitably, one or more aspects of each system had\nserious shortcomings, and they were not easily extended or modified,\npreventing them from being adopted as standard tools.\n\nIt has become clear (to this author, at least) that the \"all or\nnothing\" approach cannot succeed, since no monolithic self-contained\nsystem could possibly be agreed upon by all interested parties.  A\nmodular component approach designed for extension, where components\nmay be multiply implemented, may be the only chance for success.\nStandard inter-component APIs will make the DPS components\ncomprehensible without requiring detailed knowledge of the whole,\nlowering the barrier for contributions, and ultimately resulting in a\nrich and varied system.\n\nEach of the components of a docstring processing system should be\ndeveloped independently.  A \"best of breed\" system should be chosen,\neither merged from existing systems, and/or developed anew.  This\nsystem should be included in Python's standard library.\n\n\nPyDoc & Other Existing Systems\n------------------------------\n\nPyDoc became part of the Python standard library as of release 2.1.\nIt extracts and displays docstrings from within the Python interactive\ninterpreter, from the shell command line, and from a GUI window into a\nweb browser (HTML).  Although a very useful tool, PyDoc has several\ndeficiencies, including:\n\n- In the case of the GUI/HTML, except for some heuristic hyperlinking\n  of identifier names, no formatting of the docstrings is done.  They\n  are presented within ``<p><small><tt>`` tags to avoid unwanted line\n  wrapping.  Unfortunately, the result is not attractive.\n\n- PyDoc extracts docstrings and structural information (class\n  identifiers, method signatures, etc.) from imported module objects.\n  There are security issues involved with importing untrusted code.\n  Also, information from the source is lost when importing, such as\n  comments, \"additional docstrings\" (string literals in non-docstring\n  contexts; see PEP 258 [#PEP-258]_), and the order of definitions.\n\nThe functionality proposed in this PEP could be added to or used by\nPyDoc when serving HTML pages.  The proposed docstring processing\nsystem's functionality is much more than PyDoc needs in its current\nform.  Either an independent tool will be developed (which PyDoc may\nor may not use), or PyDoc could be expanded to encompass this\nfunctionality and *become* the docstring processing system (or one\nsuch system).  That decision is beyond the scope of this PEP.\n\nSimilarly for other existing docstring processing systems, their\nauthors may or may not choose compatibility with this framework.\nHowever, if this framework is accepted and adopted as the Python\nstandard, compatibility will become an important consideration in\nthese systems' future.\n\n\nSpecification\n=============\n\nThe docstring processing system framework is broken up as follows:\n\n1. Docstring conventions.  Documents issues such as:\n\n   - What should be documented where.\n\n   - First line is a one-line synopsis.\n\n   PEP 257 [#PEP-257]_ documents some of these issues.\n\n2. Docstring processing system design specification.  Documents\n   issues such as:\n\n   - High-level spec: what a DPS does.\n\n   - Command-line interface for executable script.\n\n   - System Python API.\n\n   - Docstring extraction rules.\n\n   - Readers, which encapsulate the input context.\n\n   - Parsers.\n\n   - Document tree: the intermediate internal data structure.

    "content": "PEP: 257\nTitle: Docstring Conventions\nVersion: $Revision$\nLast-Modified: $Date$\nAuthors: David Goodger <goodger@python.org>,\n         Guido van Rossum <guido@python.org>\nDiscussions-To: doc-sig@python.org\nStatus: Active\nType: Informational\nContent-Type: text/x-rst\nCreated: 29-May-2001\nPost-History: 13-Jun-2001\n\n\nAbstract\n========\n\nThis PEP documents the semantics and conventions associated with\nPython docstrings.\n\n\nRationale\n=========\n\nThe aim of this PEP is to standardize the high-level structure of\ndocstrings: what they should contain, and how to say it (without\ntouching on any markup syntax within docstrings).  The PEP contains\nconventions, not laws or syntax.\n\n    \"A universal convention supplies all of maintainability, clarity,\n    consistency, and a foundation for good programming habits too.\n    What it doesn't do is insist that you follow it against your will.\n    That's Python!\"\n\n    -- Tim Peters on comp.lang.python, 2001-06-16\n\nIf you violate these conventions, the worst you'll get is some dirty\nlooks.  But some software (such as the Docutils_ docstring processing\nsystem [1]_ [2]_) will be aware of the conventions, so following them\nwill get you the best results.\n\n\nSpecification\n=============\n\nWhat is a Docstring?\n--------------------\n\nA docstring is a string literal that occurs as the first statement in\na module, function, class, or method definition.  Such a docstring\nbecomes the ``__doc__`` special attribute of that object.\n\nAll modules should normally have docstrings, and all functions and\nclasses exported by a module should also have docstrings.  Public\nmethods (including the ``__init__`` constructor) should also have\ndocstrings.  A package may be documented in the module docstring of\nthe ``__init__.py`` file in the package directory.\n\nString literals occurring elsewhere in Python code may also act as\ndocumentation.  They are not recognized by the Python bytecode\ncompiler and are not accessible as runtime object attributes (i.e. not\nassigned to ``__doc__``), but two types of extra docstrings may be\nextracted by software tools:\n\n1. String literals occurring immediately after a simple assignment at\n   the top level of a module, class, or ``__init__`` method are called\n   \"attribute docstrings\".\n\n2. String literals occurring immediately after another docstring are\n   called \"additional docstrings\".\n\nPlease see PEP 258, \"Docutils Design Specification\" [2]_, for a\ndetailed description of attribute and additional docstrings.\n\nXXX Mention docstrings of 2.2 properties.\n\nFor consistency, always use ``\"\"\"triple double quotes\"\"\"`` around\ndocstrings.  Use ``r\"\"\"raw triple double quotes\"\"\"`` if you use any\nbackslashes in your docstrings.  For Unicode docstrings, use\n``u\"\"\"Unicode triple-quoted strings\"\"\"``.\n\nThere are two forms of docstrings: one-liners and multi-line\ndocstrings.\n\n\nOne-line Docstrings\n--------------------\n\nOne-liners are for really obvious cases.  They should really fit on\none line.  For example::\n\n    def kos_root():\n        \"\"\"Return the pathname of the KOS root directory.\"\"\"\n        global _kos_root\n        if _kos_root: return _kos_root\n        ...\n\nNotes:\n\n- Triple quotes are used even though the string fits on one line.\n  This makes it easy to later expand it.\n\n- The closing quotes are on the same line as the opening quotes.  This\n  looks better for one-liners.\n\n- There's no blank line either before or after the docstring.\n\n- The docstring is a phrase ending in a period.  It prescribes the\n  function or method's effect as a command (\"Do this\", \"Return that\"),\n  not as a description; e.g. don't write \"Returns the pathname ...\".\n\n- The one-line docstring should NOT be a \"signature\" reiterating the\n  function/method parameters (which can be obtained by introspection).\n  Don't do::\n\n      def function(a, b):\n          \"\"\"function(a, b) -> list\"\"\"\n\n  This type of docstring is only appropriate for C functions (such as\n  built-ins), where introspection is not possible.  However, the\n  nature of the *return value* cannot be determined by introspection,\n  so it should be mentioned.  The preferred form for such a docstring\n  would be something like::\n\n      def function(a, b):\n          \"\"\"Do X and return a list.\"\"\"\n\n  (Of course \"Do X\" should be replaced by a useful description!)\n\n\nMulti-line Docstrings\n----------------------\n\nMulti-line docstrings consist of a summary line just like a one-line\ndocstring, followed by a blank line, followed by a more elaborate\ndescription.  The summary line may be used by automatic indexing\ntools; it is important that it fits on one line and is separated from\nthe rest of the docstring by a blank line.  The summary line may be on\nthe same line as the opening quotes or on the next line.  The entire\ndocstring is indented the same as the quotes at its first line (see\nexample below).\n\nInsert a blank line before and after all docstrings (one-line or\nmulti-line) that document a class -- generally speaking, the class's\nmethods are separated from each other by a single blank line, and the\ndocstring needs to be offset from the first method by a blank line;\nfor symmetry, put a blank line between the class header and the\ndocstring.  Docstrings documenting functions or methods generally\ndon't have this requirement, unless the function or method's body is\nwritten as a number of blank-line separated sections -- in this case,\ntreat the docstring as another section, and precede it with a blank\nline.\n\nThe docstring of a script (a stand-alone program) should be usable as\nits \"usage\" message, printed when the script is invoked with incorrect\nor missing arguments (or perhaps with a \"-h\" option, for \"help\").\nSuch a docstring should document the script's function and command\nline syntax, environment variables, and files.  Usage messages can be\nfairly elaborate (several screens full) and should be sufficient for a\nnew user to use the command properly, as well as a complete quick\nreference to all options and arguments for the sophisticated user.\n\nThe docstring for a module should generally list the classes,\nexceptions and functions (and any other objects) that are exported by\nthe module, with a one-line summary of each.  (These summaries\ngenerally give less detail than the summary line in the object's\ndocstring.)  The docstring for a package (i.e., the docstring of the\npackage's ``__init__.py`` module) should also list the modules and\nsubpackages exported by the package.\n\nThe docstring for a function or method should summarize its behavior\nand document its arguments, return value(s), side effects, exceptions\nraised, and restrictions on when it can be called (all if applicable).\nOptional arguments should be indicated.  It should be documented\nwhether keyword arguments are part of the interface.\n\nThe docstring for a class should summarize its behavior and list the\npublic methods and instance variables.  If the class is intended to be\nsubclassed, and has an additional interface for subclasses, this\ninterface should be listed separately (in the docstring).  The class\nconstructor should be documented in the docstring for its ``__init__``\nmethod.  Individual methods should be documented by their own\ndocstring.\n\nIf a class subclasses another class and its behavior is mostly\ninherited from that class, its docstring should mention this and\nsummarize the differences.  Use the verb \"override\" to indicate that a\nsubclass method replaces a superclass method and does not call the\nsuperclass method; use the verb \"extend\" to indicate that a subclass\nmethod calls the superclass method (in addition to its own behavior).\n\n*Do not* use the Emacs convention of mentioning the arguments of\nfunctions or methods in upper case in running text.  Python is case\nsensitive and the argument names can be used for keyword arguments, so\nthe docstring should document the correct argument names.  It is best\nto list each argument on a separate line.  For example::\n\n    def complex(real=0.0, imag=0.0):\n        \"\"\"Form a complex number.\n\n        Keyword arguments:\n        real -- the real part (default 0.0)\n        imag -- the imaginary part (default 0.0)\n\n        \"\"\"\n        if imag == 0.0 and real == 0.0: return complex_zero\n        ...\n\nThe BDFL [3]_ recommends inserting a blank line between the last\nparagraph in a multi-line docstring and its closing quotes, placing\nthe closing quotes on a line by themselves.  This way, Emacs'\n``fill-paragraph`` command can be used on it.\n\n\nHandling Docstring Indentation\n------------------------------\n\nDocstring processing tools will strip a uniform amount of indentation\nfrom the second and further lines of the docstring, equal to the\nminimum indentation of all non-blank lines after the first line.  Any\nindentation in the first line of the docstring (i.e., up to the first\nnewline) is insignificant and removed.  Relative indentation of later\nlines in the docstring is retained.  Blank lines should be removed\nfrom the beginning and end of the docstring.\n\nSince code is much more precise than words, here is an implementation\nof the algorithm::\n\n    def trim(docstring):\n        if not docstring:\n            return ''\n        # Convert tabs to spaces (following the normal Python rules)\n        # and split into a list of lines:\n        lines = docstring.expandtabs().splitlines()\n        # Determine minimum indentation (first line doesn't count):\n        indent = sys.maxint\n        for line in lines[1:]:\n            stripped = line.lstrip()\n            if stripped:\n                indent = min(indent, len(line) - len(stripped))\n        # Remove indentation (first line is special):\n        trimmed = [lines[0].strip()]\n        if indent < sys.maxint:\n            for line in lines[1:]:\n                trimmed.append(line[indent:].rstrip())\n        # Strip off trailing and leading blank lines:\n        while trimmed and not trimmed[-1]:\n            trimmed.pop()\n        while trimmed and not trimmed[0]:\n            trimmed.pop(0)\n        # Return a single string:\n        return '\\n'.join(trimmed)\n\nThe docstring in this example contains two newline characters and is\ntherefore 3 lines long.  The first and last lines are blank::\n\n    def foo():\n        \"\"\"\n        This is the second line of the docstring.\n        \"\"\"\n\nTo illustrate::\n\n    >>> print repr(foo.__doc__)\n    '\\n    This is the second line of the docstring.\\n    '\n    >>> foo.__doc__.splitlines()\n    ['', '    This is the second line of the docstring.', '    ']\n    >>> trim(foo.__doc__)\n    'This is the second line of the docstring.'\n\nOnce trimmed, these docstrings are equivalent::\n\n    def foo():\n        \"\"\"A multi-line\n        docstring.\n        \"\"\"\n\n    def bar():\n        \"\"\"\n        A multi-line\n        docstring.\n        \"\"\"\n\n\nReferences and Footnotes\n========================\n\n..

The rationale\nand high-level concepts of a DPS are documented in PEP 256, \"Docstring\nProcessing System Framework\" [#PEP-256]_.  Also see PEP 256 for a\n\"Road Map to the Docstring PEPs\".\n\nDocutils is being designed modularly so that any of its components can\nbe replaced easily.  In addition, Docutils is not limited to the\nprocessing of Python docstrings; it processes standalone documents as\nwell, in several contexts.\n\nNo changes to the core Python language are required by this PEP.  Its\ndeliverables consist of a package for the standard library and its\ndocumentation.\n\n\n===============\n Specification\n===============\n\nDocutils Project Model\n======================\n\nProject components and data flow::\n\n                     +---------------------------+\n                     |        Docutils:          |\n                     | docutils.core.Publisher,  |\n                     | docutils.core.publish_*() |\n                     +---------------------------+\n                      /            |            \\\n                     /             |             \\\n            1,3,5   /        6     |              \\ 7\n           +--------+       +-------------+       +--------+\n           | READER | ----> | TRANSFORMER | ====> | WRITER |\n           +--------+       +-------------+       +--------+\n            /     \\\\                                  |\n           /       \\\\                                 |\n     2    /      4  \\\\                             8  |\n    +-------+   +--------+                        +--------+\n    | INPUT |   | PARSER |                        | OUTPUT |\n    +-------+   +--------+                        +--------+\n\nThe numbers above each component indicate the path a document's data\ntakes.  Double-width lines between Reader & Parser and between\nTransformer & Writer indicate that data sent along these paths should\nbe standard (pure & unextended) Docutils doc trees.  Single-width\nlines signify that internal tree extensions or completely unrelated\nrepresentations are possible, but they must be supported at both ends.\n\n\nPublisher\n---------\n\nThe ``docutils.core`` module contains a \"Publisher\" facade class and\nseveral convenience functions: \"publish_cmdline()\" (for command-line\nfront ends), \"publish_file()\" (for programmatic use with file-like\nI/O), and \"publish_string()\" (for programmatic use with string I/O).\nThe Publisher class encapsulates the high-level logic of a Docutils\nsystem.  The Publisher class has overall responsibility for\nprocessing, controlled by the ``Publisher.publish()`` method:\n\n1. Set up internal settings (may include config files & command-line\n   options) and I/O objects.\n\n2. Call the Reader object to read data from the source Input object\n   and parse the data with the Parser object.  A document object is\n   returned.\n\n3. Set up and apply transforms via the Transformer object attached to\n   the document.\n\n4. Call the Writer object which translates the document to the final\n   output format and writes the formatted data to the destination\n   Output object.  Depending on the Output object, the output may be\n   returned from the Writer, and then from the ``publish()`` method.\n\nCalling the \"publish\" function (or instantiating a \"Publisher\" object)\nwith component names will result in default behavior.  For custom\nbehavior (customizing component settings), create custom component\nobjects first, and pass *them* to the Publisher or ``publish_*``\nconvenience functions.\n\n\nReaders\n-------\n\nReaders understand the input context (where the data is coming from),\nsend the whole input or discrete \"chunks\" to the parser, and provide\nthe context to bind the chunks together back into a cohesive whole.\n\nEach reader is a module or package exporting a \"Reader\" class with a\n\"read\" method.  The base \"Reader\" class can be found in the\n``docutils/readers/__init__.py`` module.\n\nMost Readers will have to be told what parser to use.  So far (see the\nlist of examples below), only the Python Source Reader (\"PySource\";\nstill incomplete) will be able to determine the parser on its own.\n\nResponsibilities:\n\n* Get input text from the source I/O.\n\n* Pass the input text to the parser, along with a fresh `document\n  tree`_ root.\n\nExamples:\n\n* Standalone (Raw/Plain): Just read a text file and process it.\n  The reader needs to be told which parser to use.\n\n  The \"Standalone Reader\" has been implemented in module\n  ``docutils.readers.standalone``.\n\n* Python Source: See `Python Source Reader`_ below.  This Reader is\n  currently in development in the Docutils sandbox.\n\n* Email: RFC-822 headers, quoted excerpts, signatures, MIME parts.\n\n* PEP: RFC-822 headers, \"PEP xxxx\" and \"RFC xxxx\" conversion to URIs.\n  The \"PEP Reader\" has been implemented in module\n  ``docutils.readers.pep``; see PEP 287 and PEP 12.\n\n* Wiki: Global reference lookups of \"wiki links\" incorporated into\n  transforms.  (CamelCase only or unrestricted?)  Lazy\n  indentation?\n\n* Web Page: As standalone, but recognize meta fields as meta tags.\n  Support for templates of some sort?  (After ``<body>``, before\n  ``</body>``?)\n\n* FAQ: Structured \"question & answer(s)\" constructs.\n\n* Compound document: Merge chapters into a book.  Master manifest\n  file?\n\n\nParsers\n-------\n\nParsers analyze their input and produce a Docutils `document tree`_.\nThey don't know or care anything about the source or destination of\nthe data.\n\nEach input parser is a module or package exporting a \"Parser\" class\nwith a \"parse\" method.  The base \"Parser\" class can be found in the\n``docutils/parsers/__init__.py`` module.\n\nResponsibilities: Given raw input text and a doctree root node,\npopulate the doctree by parsing the input text.\n\nExample: The only parser implemented so far is for the\nreStructuredText markup.  It is implemented in the\n``docutils/parsers/rst/`` package.\n\nThe development and integration of other parsers is possible and\nencouraged.\n\n\n.. _transforms:\n\nTransformer\n-----------\n\nThe Transformer class, in ``docutils/transforms/__init__.py``, stores\ntransforms and applies them to documents.  A transformer object is\nattached to every new document tree.  The Publisher_ calls\n``Transformer.apply_transforms()`` to apply all stored transforms to\nthe document tree.  Transforms change the document tree from one form\nto another, add to the tree, or prune it.  Transforms resolve\nreferences and footnote numbers, process interpreted text, and do\nother context-sensitive processing.\n\nSome transforms are specific to components (Readers, Parser, Writers,\nInput, Output).  Standard component-specific transforms are specified\nin the ``default_transforms`` attribute of component classes.  After\nthe Reader has finished processing, the Publisher_ calls\n``Transformer.populate_from_components()`` with a list of components\nand all default transforms are stored.\n\nEach transform is a class in a module in the ``docutils/transforms/``\npackage, a subclass of ``docutils.tranforms.Transform``.  Transform\nclasses each have a ``default_priority`` attribute which is used by\nthe Transformer to apply transforms in order (low to high).  The\ndefault priority can be overridden when adding transforms to the\nTransformer object.\n\nTransformer responsibilities:\n\n* Apply transforms to the document tree, in priority order.\n\n* Store a mapping of component type name ('reader', 'writer', etc.) to\n  component objects.  These are used by certain transforms (such as\n  \"components.Filter\") to determine suitability.\n\nTransform responsibilities:\n\n* Modify a doctree in-place, either purely transforming one structure\n  into another, or adding new structures based on the doctree and/or\n  external data.\n\nExamples of transforms (in the ``docutils/transforms/`` package):\n\n* frontmatter.DocInfo: Conversion of document metadata (bibliographic\n  information).\n\n* references.AnonymousHyperlinks: Resolution of anonymous references\n  to corresponding targets.\n\n* parts.Contents: Generates a table of contents for a document.\n\n* document.Merger: Combining multiple populated doctrees into one.\n  (Not yet implemented or fully understood.)\n\n* document.Splitter: Splits a document into a tree-structure of\n  subdocuments, perhaps by section.  It will have to transform\n  references appropriately.  (Neither implemented not remotely\n  understood.)\n\n* components.Filter: Includes or excludes elements which depend on a\n  specific Docutils component.\n\n\nWriters\n-------\n\nWriters produce the final output (HTML, XML, TeX, etc.).  Writers\ntranslate the internal `document tree`_ structure into the final data\nformat, possibly running Writer-specific transforms_ first.\n\nBy the time the document gets to the Writer, it should be in final\nform.  The Writer's job is simply (and only) to translate from the\nDocutils doctree structure to the target format.  Some small\ntransforms may be required, but they should be local and\nformat-specific.\n\nEach writer is a module or package exporting a \"Writer\" class with a\n\"write\" method.  The base \"Writer\" class can be found in the\n``docutils/writers/__init__.py`` module.\n\nResponsibilities:\n\n* Translate doctree(s) into specific output formats.\n\n  - Transform references into format-native forms.\n\n* Write the translated output to the destination I/O.\n\nExamples:\n\n* XML: Various forms, such as:\n\n  - Docutils XML (an expression of the internal document tree,\n    implemented as ``docutils.writers.docutils_xml``).\n\n  - DocBook (being implemented in the Docutils sandbox).\n\n* HTML (XHTML 1.4 transitional implemented as ``docutils.writers.html4css1``).\n\n* PDF (a ReportLabs interface is being developed in the Docutils\n  sandbox).\n\n* LaTeX (implemented as ``docutils.writers.latex2e``).\n\n* Docutils-native pseudo-XML (implemented as\n  ``docutils.writers.pseudoxml``, used for testing).\n\n* Plain text\n\n* reStructuredText?\n\n\nInput/Output\n------------\n\nI/O classes provide a uniform API for low-level input and output.\nSubclasses will exist for a variety of input/output mechanisms.\nHowever, they can be considered an implementation detail.  Most\napplications should be satisfied using one of the convenience\nfunctions associated with the Publisher_.\n\nI/O classes are currently in the preliminary stages; there's a lot of\nwork yet to be done.  Issues:\n\n* How to represent multi-file input (files & directories) in the API?\n\n* How to represent multi-file output?  Perhaps \"Writer\" variants, one\n  for each output distribution type?  Or Output objects with\n  associated transforms?\n\nResponsibilities:\n\n* Read data from the input source (Input objects) or write data to the\n  output destination (Output objects).\n\nExamples of input sources:\n\n* A single file on disk or a stream (implemented as\n  ``docutils.io.FileInput``).\n\n* Multiple files on disk (``MultiFileInput``?).\n\n* Python source files: modules and packages.\n\n* Python strings, as received from a client application\n  (implemented as ``docutils.io.StringInput``).\n\nExamples of output destinations:\n\n* A single file on disk or a stream (implemented as\n  ``docutils.io.FileOutput``).\n\n* A tree of directories and files on disk.\n\n* A Python string, returned to a client application (implemented as\n  ``docutils.io.StringOutput``).\n\n* No output; useful for programmatic applications where only a portion\n  of the normal output is to be used (implemented as\n  ``docutils.io.NullOutput``).\n\n* A single tree-shaped data structure in memory.\n\n* Some other set of data structures in memory.\n\n\nDocutils Package Structure\n==========================\n\n* Package \"docutils\".\n\n  - Module \"__init__.py\" contains: class \"Component\", a base class for\n    Docutils components; class \"SettingsSpec\", a base class for\n    specifying runtime settings (used by docutils.frontend); and class\n    \"TransformSpec\", a base class for specifying transforms.\n\n  - Module \"docutils.core\" contains facade class \"Publisher\" and\n    convenience functions.

These modules are\n  installed only if they're not already present in the Python\n  installation.\n\n  - ``extras/roman.py`` contains Roman numeral conversion routines.\n\n\nFront-End Tools\n===============\n\nThe ``tools/`` directory contains several front ends for common\nDocutils processing.  See `Docutils Front-End Tools`_ for details.\n\n.. _Docutils Front-End Tools:\n   https://docutils.sourceforge.io/docs/user/tools.html\n\n\nDocument Tree\n=============\n\nA single intermediate data structure is used internally by Docutils,\nin the interfaces between components; it is defined in the\n``docutils.nodes`` module.  It is not required that this data\nstructure be used *internally* by any of the components, just\n*between* components as outlined in the diagram in the `Docutils\nProject Model`_ above.\n\nCustom node types are allowed, provided that either (a) a transform\nconverts them to standard Docutils nodes before they reach the Writer\nproper, or (b) the custom node is explicitly supported by certain\nWriters, and is wrapped in a filtered \"pending\" node.  An example of\ncondition (a) is the `Python Source Reader`_ (see below), where a\n\"stylist\" transform converts custom nodes.  The HTML ``<meta>`` tag is\nan example of condition (b); it is supported by the HTML Writer but\nnot by others.  The reStructuredText \"meta\" directive creates a\n\"pending\" node, which contains knowledge that the embedded \"meta\" node\ncan only be handled by HTML-compatible writers.  The \"pending\" node is\nresolved by the ``docutils.transforms.components.Filter`` transform,\nwhich checks that the calling writer supports HTML; if it doesn't, the\n\"pending\" node (and enclosed \"meta\" node) is removed from the\ndocument.\n\nThe document tree data structure is similar to a DOM tree, but with\nspecific node names (classes) instead of DOM's generic nodes. The\nschema is documented in an XML DTD (eXtensible Markup Language\nDocument Type Definition), which comes in two parts:\n\n* the Docutils Generic DTD, docutils.dtd_, and\n\n* the OASIS Exchange Table Model, soextbl.dtd_.\n\nThe DTD defines a rich set of elements, suitable for many input and\noutput formats.  The DTD retains all information necessary to\nreconstruct the original input text, or a reasonable facsimile\nthereof.\n\nSee `The Docutils Document Tree`_ for details (incomplete).\n\n\nError Handling\n==============\n\nWhen the parser encounters an error in markup, it inserts a system\nmessage (DTD element \"system_message\").  There are five levels of\nsystem messages:\n\n* Level-0, \"DEBUG\": an internal reporting issue.  There is no effect\n  on the processing.  Level-0 system messages are handled separately\n  from the others.\n\n* Level-1, \"INFO\": a minor issue that can be ignored.  There is little\n  or no effect on the processing.  Typically level-1 system messages\n  are not reported.\n\n* Level-2, \"WARNING\": an issue that should be addressed.  If ignored,\n  there may be minor problems with the output.  Typically level-2\n  system messages are reported but do not halt processing.\n\n* Level-3, \"ERROR\": a major issue that should be addressed.  If\n  ignored, the output will contain unpredictable errors.  Typically\n  level-3 system messages are reported but do not halt processing.\n\n* Level-4, \"SEVERE\": a critical error that must be addressed.\n  Typically level-4 system messages are turned into exceptions which\n  do halt processing.  If ignored, the output will contain severe\n  errors.\n\nAlthough the initial message levels were devised independently, they\nhave a strong correspondence to `VMS error condition severity\nlevels`_; the names in quotes for levels 1 through 4 were borrowed\nfrom VMS.  Error handling has since been influenced by the `log4j\nproject`_.\n\n\nPython Source Reader\n====================\n\nThe Python Source Reader (\"PySource\") is the Docutils component that\nreads Python source files, extracts docstrings in context, then\nparses, links, and assembles the docstrings into a cohesive whole.  It\nis a major and non-trivial component, currently under experimental\ndevelopment in the Docutils sandbox.  High-level design issues are\npresented here.\n\n\nProcessing Model\n----------------\n\nThis model will evolve over time, incorporating experience and\ndiscoveries.\n\n1. The PySource Reader uses an Input class to read in Python packages\n   and modules, into a tree of strings.\n\n2. The Python modules are parsed, converting the tree of strings into\n   a tree of abstract syntax trees with docstring nodes.\n\n3. The abstract syntax trees are converted into an internal\n   representation of the packages/modules.  Docstrings are extracted,\n   as well as code structure details.  See `AST Mining`_ below.\n   Namespaces are constructed for lookup in step 6.\n\n4. One at a time, the docstrings are parsed, producing standard\n   Docutils doctrees.\n\n5. PySource assembles all the individual docstrings' doctrees into a\n   Python-specific custom Docutils tree paralleling the\n   package/module/class structure; this is a custom Reader-specific\n   internal representation (see the `Docutils Python Source DTD`_).\n   Namespaces must be merged: Python identifiers, hyperlink targets.\n\n6. Cross-references from docstrings (interpreted text) to Python\n   identifiers are resolved according to the Python namespace lookup\n   rules.  See `Identifier Cross-References`_ below.\n\n7. A \"Stylist\" transform is applied to the custom doctree (by the\n   Transformer_), custom nodes are rendered using standard nodes as\n   primitives, and a standard document tree is emitted.  See `Stylist\n   Transforms`_ below.\n\n8. Other transforms are applied to the standard doctree by the\n   Transformer_.\n\n9. The standard doctree is sent to a Writer, which translates the\n   document into a concrete format (HTML, PDF, etc.).\n\n10. The Writer uses an Output class to write the resulting data to its\n    destination (disk file, directories and files, etc.).\n\n\nAST Mining\n----------\n\nAbstract Syntax Tree mining code will be written (or adapted) that\nscans a parsed Python module, and returns an ordered tree containing\nthe names, docstrings (including attribute and additional docstrings;\nsee below), and additional info (in parentheses below) of all of the\nfollowing objects:\n\n* packages\n* modules\n* module attributes (+ initial values)\n* classes (+ inheritance)\n* class attributes (+ initial values)\n* instance attributes (+ initial values)\n* methods (+ parameters & defaults)\n* functions (+ parameters & defaults)\n\n(Extract comments too?  For example, comments at the start of a module\nwould be a good place for bibliographic field lists.)\n\nIn order to evaluate interpreted text cross-references, namespaces for\neach of the above will also be required.\n\nSee the python-dev/docstring-develop thread \"AST mining\", started on\n2001-08-14.\n\n\nDocstring Extraction Rules\n--------------------------\n\n1. What to examine:\n\n   a) If the \"``__all__``\" variable is present in the module being\n      documented, only identifiers listed in \"``__all__``\" are\n      examined for docstrings.\n\n   b) In the absence of \"``__all__``\", all identifiers are examined,\n      except those whose names are private (names begin with \"_\" but\n      don't begin and end with \"__\").\n\n   c) 1a and 1b can be overridden by runtime settings.\n\n2. Where:\n\n   Docstrings are string literal expressions, and are recognized in\n   the following places within Python modules:\n\n   a) At the beginning of a module, function definition, class\n      definition, or method definition, after any comments.  This is\n      the standard for Python ``__doc__`` attributes.\n\n   b) Immediately following a simple assignment at the top level of a\n      module, class definition, or ``__init__`` method definition,\n      after any comments.  See `Attribute Docstrings`_ below.\n\n   c) Additional string literals found immediately after the\n      docstrings in (a) and (b) will be recognized, extracted, and\n      concatenated.  See `Additional Docstrings`_ below.\n\n   d) @@@ 2.2-style \"properties\" with attribute docstrings?  Wait for\n      syntax?\n\n3. How:\n\n   Whenever possible, Python modules should be parsed by Docutils, not\n   imported.  There are several reasons:\n\n   - Importing untrusted code is inherently insecure.\n\n   - Information from the source is lost when using introspection to\n     examine an imported module, such as comments and the order of\n     definitions.\n\n   - Docstrings are to be recognized in places where the byte-code\n     compiler ignores string literal expressions (2b and 2c above),\n     meaning importing the module will lose these docstrings.\n\n   Of course, standard Python parsing tools such as the \"parser\"\n   library module should be used.\n\n   When the Python source code for a module is not available\n   (i.e. only the ``.pyc`` file exists) or for C extension modules, to\n   access docstrings the module can only be imported, and any\n   limitations must be lived with.\n\nSince attribute docstrings and additional docstrings are ignored by\nthe Python byte-code compiler, no namespace pollution or runtime bloat\nwill result from their use.  They are not assigned to ``__doc__`` or\nto any other attribute.  The initial parsing of a module may take a\nslight performance hit.\n\n\nAttribute Docstrings\n''''''''''''''''''''\n\n(This is a simplified version of PEP 224 [#PEP-224]_.)\n\nA string literal immediately following an assignment statement is\ninterpreted by the docstring extraction machinery as the docstring of\nthe target of the assignment statement, under the following\nconditions:\n\n1. The assignment must be in one of the following contexts:\n\n   a) At the top level of a module (i.e., not nested inside a compound\n      statement such as a loop or conditional): a module attribute.\n\n   b) At the top level of a class definition: a class attribute.\n\n   c) At the top level of the \"``__init__``\" method definition of a\n      class: an instance attribute.  Instance attributes assigned in\n      other methods are assumed to be implementation details.  (@@@\n      ``__new__`` methods?)\n\n   d) A function attribute assignment at the top level of a module or\n      class definition.\n\n   Since each of the above contexts are at the top level (i.e., in the\n   outermost suite of a definition), it may be necessary to place\n   dummy assignments for attributes assigned conditionally or in a\n   loop.\n\n2. The assignment must be to a single target, not to a list or a tuple\n   of targets.\n\n3. The form of the target:\n\n   a) For contexts 1a and 1b above, the target must be a simple\n      identifier (not a dotted identifier, a subscripted expression,\n      or a sliced expression).\n\n   b) For context 1c above, the target must be of the form\n      \"``self.attrib``\", where \"``self``\" matches the \"``__init__``\"\n      method's first parameter (the instance parameter) and \"attrib\"\n      is a simple identifier as in 3a.\n\n   c) For context 1d above, the target must be of the form\n      \"``name.attrib``\", where \"``name``\" matches an already-defined\n      function or method name and \"attrib\" is a simple identifier as\n      in 3a.\n\nBlank lines may be used after attribute docstrings to emphasize the\nconnection between the assignment and the docstring.\n\nExamples::\n\n    g = 'module attribute (module-global variable)'\n    \"\"\"This is g's docstring.\"\"\"\n\n    class AClass:\n\n        c = 'class attribute'\n        \"\"\"This is AClass.c's docstring.\"\"\"\n\n        def __init__(self):\n            \"\"\"Method __init__'s docstring.\"\"\"\n\n            self.i = 'instance attribute'\n            \"\"\"This is self.i's docstring.\"\"\"\n\n    def f(x):\n        \"\"\"Function f's docstring.\"\"\"\n        return x**2\n\n    f.a = 1\n    \"\"\"Function attribute f.a's docstring.\"\"\"\n\n\nAdditional Docstrings\n'''''''''''''''''''''\n\n(This idea was adapted from PEP 216 [#PEP-216]_.)\n\nMany programmers would like to make extensive use of docstrings for\nAPI documentation.  However, docstrings do take up space in the\nrunning program, so some programmers are reluctant to \"bloat up\" their\ncode.  Also, not all API documentation is applicable to interactive\nenvironments, where ``__doc__`` would be displayed.\n\nDocutils' docstring extraction tools will concatenate all string\nliteral expressions which appear at the beginning of a definition or\nafter a simple assignment.  Only the first strings in definitions will\nbe available as ``__doc__``, and can be used for brief usage text\nsuitable for interactive sessions; subsequent string literals and all\nattribute docstrings are ignored by the Python byte-code compiler and\nmay contain more extensive API information.\n\nExample::\n\n    def function(arg):\n        \"\"\"This is __doc__, function's docstring.\"\"\"\n        \"\"\"\n        This is an additional docstring, ignored by the byte-code\n        compiler, but extracted by Docutils.\n        \"\"\"\n        pass\n\n.. topic:: Issue: ``from __future__ import``\n\n   This would break \"``from __future__ import``\" statements introduced\n   in Python 2.1 for multiple module docstrings (main docstring plus\n   additional docstring(s)).  The Python Reference Manual specifies:\n\n       A future statement must appear near the top of the module.  The\n       only lines that can appear before a future statement are:\n\n       * the module docstring (if any),\n       * comments,\n       * blank lines, and\n       * other future statements.\n\n   Resolution?\n\n   1. Should we search for docstrings after a ``__future__``\n      statement?  Very ugly.\n\n   2. Redefine ``__future__`` statements to allow multiple preceding\n      string literals?\n\n   3. Or should we not even worry about this?  There probably\n      shouldn't be ``__future__`` statements in production code, after\n      all.  Perhaps modules with ``__future__`` statements will simply\n      have to put up with the single-docstring limitation.\n\n\nChoice of Docstring Format\n--------------------------\n\nRather than force everyone to use a single docstring format, multiple\ninput formats are allowed by the processing system.  A special\nvariable, ``__docformat__``, may appear at the top level of a module\nbefore any function or class definitions.  Over time or through\ndecree, a standard format or set of formats should emerge.\n\nA module's ``__docformat__`` variable only applies to the objects\ndefined in the module's file.  In particular, the ``__docformat__``\nvariable in a package's ``__init__.py`` file does not apply to objects\ndefined in subpackages and submodules.\n\nThe ``__docformat__`` variable is a string containing the name of the\nformat being used, a case-insensitive string matching the input\nparser's module or package name (i.e., the same name as required to\n\"import\" the module or package), or a registered alias.  If no\n``__docformat__`` is specified, the default format is \"plaintext\" for\nnow; this may be changed to the standard format if one is ever\nestablished.\n\nThe ``__docformat__`` string may contain an optional second field,\nseparated from the format name (first field) by a single space: a\ncase-insensitive language identifier as defined in RFC 1766.  A\ntypical language identifier consists of a 2-letter language code from\n`ISO 639`_ (3-letter codes used only if no 2-letter code exists; RFC\n1766 is currently being revised to allow 3-letter codes).  If no\nlanguage identifier is specified, the default is \"en\" for English.\nThe language identifier is passed to the parser and can be used for\nlanguage-dependent markup features.\n\n\nIdentifier Cross-References\n---------------------------\n\nIn Python docstrings, interpreted text is used to classify and mark up\nprogram identifiers, such as the names of variables, functions,\nclasses, and modules.  If the identifier alone is given, its role is\ninferred implicitly according to the Python namespace lookup rules.\nFor functions and methods (even when dynamically assigned),\nparentheses ('()') may be included::\n\n    This function uses `another()` to do its work.\n\nFor class, instance and module attributes, dotted identifiers are used\nwhen necessary.  For example (using reStructuredText markup)::\n\n    class Keeper(Storer):\n\n        \"\"\"\n        Extend `Storer`.  Class attribute `instances` keeps track\n        of the number of `Keeper` objects instantiated.\n        \"\"\"\n\n        instances = 0\n        \"\"\"How many `Keeper` objects are there?\"\"\"\n\n        def __init__(self):\n            \"\"\"\n            Extend `Storer.__init__()` to keep track of instances.\n\n            Keep count in `Keeper.instances`, data in `self.data`.\n            \"\"\"\n            Storer.__init__(self)\n            Keeper.instances += 1\n\n            self.data = []\n            \"\"\"Store data in a list, most recent last.\"\"\"\n\n        def store_data(self, data):\n            \"\"\"\n            Extend `Storer.store_data()`; append new `data` to a\n            list (in `self.data`).\n            \"\"\"\n            self.data = data\n\nEach of the identifiers quoted with backquotes (\"`\") will become\nreferences to the definitions of the identifiers themselves.\n\n\nStylist Transforms\n------------------\n\nStylist transforms are specialized transforms specific to the PySource\nReader.  The PySource Reader doesn't have to make any decisions as to\nstyle; it just produces a logically constructed document tree, parsed\nand linked, including custom node types.  Stylist transforms\nunderstand the custom nodes created by the Reader and convert them\ninto standard Docutils nodes.\n\nMultiple Stylist transforms may be implemented and one can be chosen\nat runtime (through a \"--style\" or \"--stylist\" command-line option).\nEach Stylist transform implements a different layout or style; thus\nthe name.  They decouple the context-understanding part of the Reader\nfrom the layout-generating part of processing, resulting in a more\nflexible and robust system.  This also serves to \"separate style from\ncontent\", the SGML/XML ideal.\n\nBy keeping the piece of code that does the styling small and modular,\nit becomes much easier for people to roll their own styles.  The\n\"barrier to entry\" is too high with existing tools; extracting the\nstylist code will lower the barrier considerably.\n\n\n==========================\n References and Footnotes\n==========================\n\n..

    "content": "PEP: 287\nTitle: reStructuredText Docstring Format\nVersion: $Revision$\nLast-Modified: $Date$\nAuthor: David Goodger <goodger@python.org>\nDiscussions-To: <doc-sig@python.org>\nStatus: Draft\nType: Informational\nContent-Type: text/x-rst\nCreated: 25-Mar-2002\nPost-History: 02-Apr-2002\nReplaces: 216\n\n\nAbstract\n========\n\nWhen plaintext hasn't been expressive enough for inline documentation,\nPython programmers have sought out a format for docstrings.  This PEP\nproposes that the `reStructuredText markup`_ be adopted as a standard\nmarkup format for structured plaintext documentation in Python\ndocstrings, and for PEPs and ancillary documents as well.\nreStructuredText is a rich and extensible yet easy-to-read,\nwhat-you-see-is-what-you-get plaintext markup syntax.\n\nOnly the low-level syntax of docstrings is addressed here.  This PEP\nis not concerned with docstring semantics or processing at all (see\nPEP 256 for a \"Road Map to the Docstring PEPs\").  Nor is it an attempt\nto deprecate pure plaintext docstrings, which are always going to be\nlegitimate.  The reStructuredText markup is an alternative for those\nwho want more expressive docstrings.\n\n\nBenefits\n========\n\nProgrammers are by nature a lazy breed.  We reuse code with functions,\nclasses, modules, and subsystems.  Through its docstring syntax,\nPython allows us to document our code from within.  The \"holy grail\"\nof the Python Documentation Special Interest Group (Doc-SIG_) has been\na markup syntax and toolset to allow auto-documentation, where the\ndocstrings of Python systems can be extracted in context and processed\ninto useful, high-quality documentation for multiple purposes.\n\nDocument markup languages have three groups of customers: the authors\nwho write the documents, the software systems that process the data,\nand the readers, who are the final consumers and the most important\ngroup.  Most markups are designed for the authors and software\nsystems; readers are only meant to see the processed form, either on\npaper or via browser software.  ReStructuredText is different: it is\nintended to be easily readable in source form, without prior knowledge\nof the markup.  ReStructuredText is entirely readable in plaintext\nformat, and many of the markup forms match common usage (e.g.,\n``*emphasis*``), so it reads quite naturally.  Yet it is rich enough\nto produce complex documents, and extensible so that there are few\nlimits.  Of course, to write reStructuredText documents some prior\nknowledge is required.\n\nThe markup offers functionality and expressivity, while maintaining\neasy readability in the source text.  The processed form (HTML etc.)\nmakes it all accessible to readers: inline live hyperlinks; live links\nto and from footnotes; automatic tables of contents (with live\nlinks!); tables; images for diagrams etc.; pleasant, readable styled\ntext.\n\nThe reStructuredText parser is available now, part of the Docutils_\nproject.  Standalone reStructuredText documents and PEPs can be\nconverted to HTML; other output format writers are being worked on and\nwill become available over time.  Work is progressing on a Python\nsource \"Reader\" which will implement auto-documentation from\ndocstrings.  Authors of existing auto-documentation tools are\nencouraged to integrate the reStructuredText parser into their\nprojects, or better yet, to join forces to produce a world-class\ntoolset for the Python standard library.\n\nTools will become available in the near future, which will allow\nprogrammers to generate HTML for online help, XML for multiple\npurposes, and eventually PDF, DocBook, and LaTeX for printed\ndocumentation, essentially \"for free\" from the existing docstrings.\nThe adoption of a standard will, at the very least, benefit docstring\nprocessing tools by preventing further \"reinventing the wheel\".\n\nEventually PyDoc, the one existing standard auto-documentation tool,\ncould have reStructuredText support added.  In the interim it will\nhave no problem with reStructuredText markup, since it treats all\ndocstrings as preformatted plaintext.\n\n\nGoals\n=====\n\nThese are the generally accepted goals for a docstring format, as\ndiscussed in the Doc-SIG:\n\n1. It must be readable in source form by the casual observer.\n\n2. It must be easy to type with any standard text editor.\n\n3. It must not need to contain information which can be deduced from\n   parsing the module.\n\n4. It must contain sufficient information (structure) so it can be\n   converted to any reasonable markup format.\n\n5. It must be possible to write a module's entire documentation in\n   docstrings, without feeling hampered by the markup language.\n\nreStructuredText meets and exceeds all of these goals, and sets its\nown goals as well, even more stringent.  See `Docstring-Significant\nFeatures`_ below.\n\nThe goals of this PEP are as follows:\n\n1. To establish reStructuredText as a standard structured plaintext\n   format for docstrings (inline documentation of Python modules and\n   packages), PEPs, README-type files and other standalone documents.\n   \"Accepted\" status will be sought through Python community consensus\n   and eventual BDFL pronouncement.\n\n   Please note that reStructuredText is being proposed as *a*\n   standard, not *the only* standard.  Its use will be entirely\n   optional.  Those who don't want to use it need not.\n\n2. To solicit and address any related concerns raised by the Python\n   community.\n\n3. To encourage community support.  As long as multiple competing\n   markups are out there, the development community remains fractured.\n   Once a standard exists, people will start to use it, and momentum\n   will inevitably gather.\n\n4. To consolidate efforts from related auto-documentation projects.\n   It is hoped that interested developers will join forces and work on\n   a joint/merged/common implementation.\n\nOnce reStructuredText is a Python standard, effort can be focused on\ntools instead of arguing for a standard.  Python needs a standard set\nof documentation tools.\n\nWith regard to PEPs, one or both of the following strategies may be\napplied:\n\na) Keep the existing PEP section structure constructs (one-line\n   section headers, indented body text).  Subsections can either be\n   forbidden, or supported with reStructuredText-style underlined\n   headers in the indented body text.\n\nb) Replace the PEP section structure constructs with the\n   reStructuredText syntax.  Section headers will require underlines,\n   subsections will be supported out of the box, and body text need\n   not be indented (except for block quotes).\n\nStrategy (b) is recommended, and its implementation is complete.\n\nSupport for RFC 2822 headers has been added to the reStructuredText\nparser for PEPs (unambiguous given a specific context: the first\ncontiguous block of the document).  It may be desired to concretely\nspecify what over/underline styles are allowed for PEP section\nheaders, for uniformity.\n\n\nRationale\n=========\n\nThe lack of a standard syntax for docstrings has hampered the\ndevelopment of standard tools for extracting and converting docstrings\ninto documentation in standard formats (e.g., HTML, DocBook, TeX).\nThere have been a number of proposed markup formats and variations,\nand many tools tied to these proposals, but without a standard\ndocstring format they have failed to gain a strong following and/or\nfloundered half-finished.\n\nThroughout the existence of the Doc-SIG, consensus on a single\nstandard docstring format has never been reached.  A lightweight,\nimplicit markup has been sought, for the following reasons (among\nothers):\n\n1. Docstrings written within Python code are available from within the\n   interactive interpreter, and can be \"print\"ed.  Thus the use of\n   plaintext for easy readability.\n\n2. Programmers want to add structure to their docstrings, without\n   sacrificing raw docstring readability.  Unadorned plaintext cannot\n   be transformed (\"up-translated\") into useful structured formats.\n\n3. Explicit markup (like XML or TeX) is widely considered unreadable\n   by the uninitiated.\n\n4. Implicit markup is aesthetically compatible with the clean and\n   minimalist Python syntax.\n\nMany alternative markups for docstrings have been proposed on the\nDoc-SIG over the years; a representative sample is listed below.  Each\nis briefly analyzed in terms of the goals stated above.  Please note\nthat this is *not* intended to be an exclusive list of all existing\nmarkup systems; there are many other markups (Texinfo, Doxygen, TIM,\nYODL, AFT, ...) which are not mentioned.\n\n- XML_, SGML_, DocBook_, HTML_, XHTML_\n\n  XML and SGML are explicit, well-formed meta-languages suitable for\n  all kinds of documentation.  XML is a variant of SGML.  They are\n  best used behind the scenes, because to untrained eyes they are\n  verbose, difficult to type, and too cluttered to read comfortably as\n  source.  DocBook, HTML, and XHTML are all applications of SGML\n  and/or XML, and all share the same basic syntax and the same\n  shortcomings.\n\n- TeX_\n\n  TeX is similar to XML/SGML in that it's explicit, but not very easy\n  to write, and not easy for the uninitiated to read.\n\n- `Perl POD`_\n\n  Most Perl modules are documented in a format called POD (Plain Old\n  Documentation).  This is an easy-to-type, very low level format with\n  strong integration with the Perl parser.  Many tools exist to turn\n  POD documentation into other formats: info, HTML and man pages,\n  among others.  However, the POD syntax takes after Perl itself in\n  terms of readability.\n\n- JavaDoc_\n\n  Special comments before Java classes and functions serve to document\n  the code.  A program to extract these, and turn them into HTML\n  documentation is called javadoc, and is part of the standard Java\n  distribution.  However, JavaDoc has a very intimate relationship\n  with HTML, using HTML tags for most markup.  Thus it shares the\n  readability problems of HTML.\n\n- Setext_, StructuredText_\n\n  Early on, variants of Setext (Structure Enhanced Text), including\n  Zope Corp's StructuredText, were proposed for Python docstring\n  formatting.  Hereafter these variants will collectively be called\n  \"STexts\".  STexts have the advantage of being easy to read without\n  special knowledge, and relatively easy to write.\n\n  Although used by some (including in most existing Python\n  auto-documentation tools), until now STexts have failed to become\n  standard because:\n\n  - STexts have been incomplete.  Lacking \"essential\" constructs that\n    people want to use in their docstrings, STexts are rendered less\n    than ideal.  Note that these \"essential\" constructs are not\n    universal; everyone has their own requirements.\n\n  - STexts have been sometimes surprising.  Bits of text are\n    unexpectedly interpreted as being marked up, leading to user\n    frustration.\n\n  - SText implementations have been buggy.\n\n  - Most STexts have have had no formal specification except for the\n    implementation itself.  A buggy implementation meant a buggy spec,\n    and vice-versa.\n\n  - There has been no mechanism to get around the SText markup rules\n    when a markup character is used in a non-markup context.  In other\n    words, no way to escape markup.\n\nProponents of implicit STexts have vigorously opposed proposals for\nexplicit markup (XML, HTML, TeX, POD, etc.), and the debates have\ncontinued off and on since 1996 or earlier.\n\nreStructuredText is a complete revision and reinterpretation of the\nSText idea, addressing all of the problems listed above.\n\n\nSpecification\n=============\n\nThe specification and user documentaton for reStructuredText is\nquite extensive.  Rather than repeating or summarizing it all\nhere, links to the originals are provided.\n\nPlease first take a look at `A ReStructuredText Primer`_, a short and\ngentle introduction.  The `Quick reStructuredText`_ user reference\nquickly summarizes all of the markup constructs.  For complete and\nextensive details, please refer to the following documents:\n\n- `An Introduction to reStructuredText`_\n\n- `reStructuredText Markup Specification`_\n\n- `reStructuredText Directives`_\n\nIn addition, `Problems With StructuredText`_ explains many markup\ndecisions made with regards to StructuredText, and `A Record of\nreStructuredText Syntax Alternatives`_ records markup decisions made\nindependently.\n\n\nDocstring-Significant Features\n==============================\n\n- A markup escaping mechanism.\n\n  Backslashes (``\\``) are used to escape markup characters when needed\n  for non-markup purposes.  However, the inline markup recognition\n  rules have been constructed in order to minimize the need for\n  backslash-escapes.  For example, although asterisks are used for\n  *emphasis*, in non-markup contexts such as \"*\" or \"(*)\" or \"x * y\",\n  the asterisks are not interpreted as markup and are left unchanged.\n  For many non-markup uses of backslashes (e.g., describing regular\n  expressions), inline literals or literal blocks are applicable; see\n  the next item.\n\n- Markup to include Python source code and Python interactive\n  sessions: inline literals, literal blocks, and doctest blocks.\n\n  Inline literals use ``double-backquotes`` to indicate program I/O or\n  code snippets.  No markup interpretation (including backslash-escape\n  [``\\``] interpretation) is done within inline literals.\n\n  Literal blocks (block-level literal text, such as code excerpts or\n  ASCII graphics) are indented, and indicated with a double-colon\n  (\"::\") at the end of the preceding paragraph (right here -->)::\n\n      if literal_block:\n          text = 'is left as-is'\n          spaces_and_linebreaks = 'are preserved'\n          markup_processing = None\n\n  Doctest blocks begin with \">>> \" and end with a blank line.  Neither\n  indentation nor literal block double-colons are required.  For\n  example::\n\n      Here's a doctest block:\n\n      >>> print 'Python-specific usage examples; begun with \">>>\"'\n      Python-specific usage examples; begun with \">>>\"\n      >>> print '(cut and pasted from interactive sessions)'\n      (cut and pasted from interactive sessions)\n\n- Markup that isolates a Python identifier: interpreted text.\n\n  Text enclosed in single backquotes is recognized as \"interpreted\n  text\", whose interpretation is application-dependent.  In the\n  context of a Python docstring, the default interpretation of\n  interpreted text is as Python identifiers.  The text will be marked\n  up with a hyperlink connected to the documentation for the\n  identifier given.  Lookup rules are the same as in Python itself:\n  LGB namespace lookups (local, global, builtin).  The \"role\" of the\n  interpreted text (identifying a class, module, function, etc.) is\n  determined implicitly from the namespace lookup.  For example::\n\n      class Keeper(Storer):\n\n          \"\"\"\n          Keep data fresher longer.\n\n          Extend `Storer`.  Class attribute `instances` keeps track\n          of the number of `Keeper` objects instantiated.\n          \"\"\"\n\n          instances = 0\n          \"\"\"How many `Keeper` objects are there?\"\"\"\n\n          def __init__(self):\n              \"\"\"\n              Extend `Storer.__init__()` to keep track of\n              instances.  Keep count in `self.instances` and data\n              in `self.data`.\n              \"\"\"\n              Storer.__init__(self)\n              self.instances += 1\n\n              self.data = []\n              \"\"\"Store data in a list, most recent last.\"\"\"\n\n          def storedata(self, data):\n              \"\"\"\n              Extend `Storer.storedata()`; append new `data` to a\n              list (in `self.data`).\n              \"\"\"\n              self.data = data\n\n  Each piece of interpreted text is looked up according to the local\n  namespace of the block containing its docstring.\n\n- Markup that isolates a Python identifier and specifies its type:\n  interpreted text with roles.\n\n  Although the Python source context reader is designed not to require\n  explicit roles, they may be used.  To classify identifiers\n  explicitly, the role is given along with the identifier in either\n  prefix or suffix form::\n\n      Use :method:`Keeper.storedata` to store the object's data in\n      `Keeper.data`:instance_attribute:.\n\n  The syntax chosen for roles is verbose, but necessarily so (if\n  anyone has a better alternative, please post it to the Doc-SIG_).\n  The intention of the markup is that there should be little need to\n  use explicit roles; their use is to be kept to an absolute minimum.\n\n- Markup for \"tagged lists\" or \"label lists\": field lists.\n\n  Field lists represent a mapping from field name to field body.\n  These are mostly used for extension syntax, such as \"bibliographic\n  field lists\" (representing document metadata such as author, date,\n  and version) and extension attributes for directives (see below).\n  They may be used to implement methodologies (docstring semantics),\n  such as identifying parameters, exceptions raised, etc.; such usage\n  is beyond the scope of this PEP.\n\n  A modified RFC 2822 syntax is used, with a colon *before* as well as\n  *after* the field name.  Field bodies are more versatile as well;\n  they may contain multiple field bodies (even nested field lists).\n  For example::\n\n      :Date: 2002-03-22\n      :Version: 1\n      :Authors:\n          - Me\n          - Myself\n          - I\n\n  Standard RFC 2822 header syntax cannot be used for this construct\n  because it is ambiguous.  A word followed by a colon at the\n  beginning of a line is common in written text.\n\n- Markup extensibility: directives and substitutions.\n\n  Directives are used as an extension mechanism for reStructuredText,\n  a way of adding support for new block-level constructs without\n  adding new syntax.  Directives for images, admonitions (note,\n  caution, etc.), and tables of contents generation (among others)\n  have been implemented.  For example, here's how to place an image::\n\n      .. image:: mylogo.png\n\n  Substitution definitions allow the power and flexibility of\n  block-level directives to be shared by inline text.  For example::\n\n      The |biohazard| symbol must be used on containers used to\n      dispose of medical waste.\n\n      .. |biohazard| image:: biohazard.png\n\n- Section structure markup.\n\n  Section headers in reStructuredText use adornment via underlines\n  (and possibly overlines) rather than indentation.  For example::\n\n      This is a Section Title\n      =======================\n\n      This is a Subsection Title\n      --------------------------\n\n      This paragraph is in the subsection.\n\n      This is Another Section Title\n      =============================\n\n      This paragraph is in the second section.\n\n\nQuestions & Answers\n===================\n\n1. Is reStructuredText rich enough?\n\n   Yes, it is for most people.  If it lacks some construct that is\n   required for a specific application, it can be added via the\n   directive mechanism.  If a useful and common construct has been\n   overlooked and a suitably readable syntax can be found, it can be\n   added to the specification and parser.\n\n2. Is reStructuredText *too* rich?\n\n   For specific applications or individuals, perhaps.  In general, no.\n\n   Since the very beginning, whenever a docstring markup syntax has\n   been proposed on the Doc-SIG_, someone has complained about the\n   lack of support for some construct or other.  The reply was often\n   something like, \"These are docstrings we're talking about, and\n   docstrings shouldn't have complex markup.\"  The problem is that a\n   construct that seems superfluous to one person may be absolutely\n   essential to another.\n\n   reStructuredText takes the opposite approach: it provides a rich\n   set of implicit markup constructs (plus a generic extension\n   mechanism for explicit markup), allowing for all kinds of\n   documents.  If the set of constructs is too rich for a particular\n   application, the unused constructs can either be removed from the\n   parser (via application-specific overrides) or simply omitted by\n   convention.\n\n3. Why not use indentation for section structure, like StructuredText\n   does?  Isn't it more \"Pythonic\"?\n\n   Guido van Rossum wrote the following in a 2001-06-13 Doc-SIG post:\n\n       I still think that using indentation to indicate sectioning is\n       wrong.  If you look at how real books and other print\n       publications are laid out, you'll notice that indentation is\n       used frequently, but mostly at the intra-section level.\n       Indentation can be used to offset lists, tables, quotations,\n       examples, and the like.  (The argument that docstrings are\n       different because they are input for a text formatter is wrong:\n       the whole point is that they are also readable without\n       processing.)\n\n       I reject the argument that using indentation is Pythonic: text\n       is not code, and different traditions and conventions hold.\n       People have been presenting text for readability for over 30\n       centuries.  Let's not innovate needlessly.\n\n   See `Section Structure via Indentation`__ in `Problems With\n   StructuredText`_ for further elaboration.\n\n   __ https://docutils.sourceforge.io/docs/dev/rst/problems.html\n      #section-structure-via-indentation\n\n4. Why use reStructuredText for PEPs?  What's wrong with the existing\n   standard?\n\n   The existing standard for PEPs is very limited in terms of general\n   expressibility, and referencing is especially lacking for such a\n   reference-rich document type.  PEPs are currently converted into\n   HTML, but the results (mostly monospaced text) are less than\n   attractive, and most of the value-added potential of HTML\n   (especially inline hyperlinks) is untapped.\n\n   Making reStructuredText a standard markup for PEPs will enable much\n   richer expression, including support for section structure, inline\n   markup, graphics, and tables.  In several PEPs there are ASCII\n   graphics diagrams, which are all that plaintext documents can\n   support.  Since PEPs are made available in HTML form, the ability\n   to include proper diagrams would be immediately useful.\n\n   Current PEP practices allow for reference markers in the form \"[1]\"\n   in the text, and the footnotes/references themselves are listed in\n   a section toward the end of the document.  There is currently no\n   hyperlinking between the reference marker and the\n   footnote/reference itself (it would be possible to add this to\n   pep2html.py, but the \"markup\" as it stands is ambiguous and\n   mistakes would be inevitable).  A PEP with many references (such as\n   this one ;-) requires a lot of flipping back and forth.  When\n   revising a PEP, often new references are added or unused references\n   deleted.  It is painful to renumber the references, since it has to\n   be done in two places and can have a cascading effect (insert a\n   single new reference 1, and every other reference has to be\n   renumbered; always adding new references to the end is suboptimal).\n   It is easy for references to go out of sync.\n\n   PEPs use references for two purposes: simple URL references and\n   footnotes.  reStructuredText differentiates between the two.  A PEP\n   might contain references like this::\n\n       Abstract\n\n           This PEP proposes adding frungible doodads [1] to the core.\n           It extends PEP 9876 [2] via the BCA [3] mechanism.\n\n       ...\n\n       References and Footnotes\n\n           [1] http://www.example.org/\n\n           [2] PEP 9876, Let's Hope We Never Get Here\n               http://www.python.org/peps/pep-9876.html\n\n           [3] \"Bogus Complexity Addition\"\n\n   Reference 1 is a simple URL reference.  Reference 2 is a footnote\n   containing text and a URL.  Reference 3 is a footnote containing\n   text only.  Rewritten using reStructuredText, this PEP could look\n   like this::\n\n       Abstract\n       ========\n\n       This PEP proposes adding `frungible doodads`_ to the core.  It\n       extends PEP 9876 [#pep9876]_ via the BCA [#]_ mechanism.\n\n       ...\n\n       References & Footnotes\n       ======================\n\n       .. _frungible doodads: http://www.example.org/\n\n       .. [#pep9876] PEP 9876, Let's Hope We Never Get Here\n\n       .. [#] \"Bogus Complexity Addition\"\n\n   URLs and footnotes can be defined close to their references if\n   desired, making them easier to read in the source text, and making\n   the PEPs easier to revise.  The \"References and Footnotes\" section\n   can be auto-generated with a document tree transform.  Footnotes\n   from throughout the PEP would be gathered and displayed under a\n   standard header.  If URL references should likewise be written out\n   explicitly (in citation form), another tree transform could be\n   used.\n\n   URL references can be named (\"frungible doodads\"), and can be\n   referenced from multiple places in the document without additional\n   definitions.  When converted to HTML, references will be replaced\n   with inline hyperlinks (HTML <a> tags).  The two footnotes are\n   automatically numbered, so they will always stay in sync.  The\n   first footnote also contains an internal reference name, \"pep9876\",\n   so it's easier to see the connection between reference and footnote\n   in the source text.  Named footnotes can be referenced multiple\n   times, maintaining consistent numbering.\n\n   The \"#pep9876\" footnote could also be written in the form of a\n   citation::\n\n       It extends PEP 9876 [PEP9876]_ ...\n\n       .. [PEP9876] PEP 9876, Let's Hope We Never Get Here\n\n   Footnotes are numbered, whereas citations use text for their\n   references.\n\n5. Wouldn't it be better to keep the docstring and PEP proposals\n   separate?\n\n   The PEP markup proposal may be removed if it is deemed that there\n   is no need for PEP markup, or it could be made into a separate PEP.\n   If accepted, PEP 1, PEP Purpose and Guidelines [#PEP-1]_, and PEP\n   9, Sample PEP Template [#PEP-9]_ will be updated.\n\n   It seems natural to adopt a single consistent markup standard for\n   all uses of structured plaintext in Python, and to propose it all\n   in one place.\n\n6. The existing pep2html.py script converts the existing PEP format to\n   HTML.  How will the new-format PEPs be converted to HTML?\n\n   A new version of pep2html.py with integrated reStructuredText\n   parsing has been completed.  The Docutils project supports PEPs\n   with a \"PEP Reader\" component, including all functionality\n   currently in pep2html.py (auto-recognition of PEP & RFC references,\n   email masking, etc.).\n\n7. Who's going to convert the existing PEPs to reStructuredText?\n\n   PEP authors or volunteers may convert existing PEPs if they like,\n   but there is no requirement to do so.  The reStructuredText-based\n   PEPs will coexist with the old PEP standard.  The pep2html.py\n   mentioned in answer 6 processes both old and new standards.\n\n8. Why use reStructuredText for README and other ancillary files?\n\n   The reasoning given for PEPs in answer 4 above also applies to\n   README and other ancillary files.  By adopting a standard markup,\n   these files can be converted to attractive cross-referenced HTML\n   and put up on python.org.  Developers of other projects can also\n   take advantage of this facility for their own documentation.\n\n9. Won't the superficial similarity to existing markup conventions\n   cause problems, and result in people writing invalid markup (and\n   not noticing, because the plaintext looks natural)?  How forgiving\n   is reStructuredText of \"not quite right\" markup?\n\n   There will be some mis-steps, as there would be when moving from\n   one programming language to another.  As with any language,\n   proficiency grows with experience.  Luckily, reStructuredText is a\n   very little language indeed.\n\n   As with any syntax, there is the possibility of syntax errors.  It\n   is expected that a user will run the processing system over their\n   input and check the output for correctness.\n\n   In a strict sense, the reStructuredText parser is very unforgiving\n   (as it should be; \"In the face of ambiguity, refuse the temptation\n   to guess\" [#Zen]_ applies to parsing markup as well as computer\n   languages).  Here's design goal 3 from `An Introduction to\n   reStructuredText`_:\n\n       Unambiguous.  The rules for markup must not be open for\n       interpretation.  For any given input, there should be one and\n       only one possible output (including error output).\n\n   While unforgiving, at the same time the parser does try to be\n   helpful by producing useful diagnostic output (\"system messages\").\n   The parser reports problems, indicating their level of severity\n   (from least to most: debug, info, warning, error, severe).  The\n   user or the client software can decide on reporting thresholds;\n   they can ignore low-level problems or cause high-level problems to\n   bring processing to an immediate halt.  Problems are reported\n   during the parse as well as included in the output, often with\n   two-way links between the source of the problem and the system\n   message explaining it.\n\n10. Will the docstrings in the Python standard library modules be\n    converted to reStructuredText?\n\n    No.  Python's library reference documentation is maintained\n    separately from the source.  Docstrings in the Python standard\n    library should not try to duplicate the library reference\n    documentation.  The current policy for docstrings in the Python\n    standard library is that they should be no more than concise\n    hints, simple and markup-free (although many *do* contain ad-hoc\n    implicit markup).\n\n11. I want to write all my strings in Unicode.  Will anything\n    break?\n\n    The parser fully supports Unicode.  Docutils supports arbitrary\n    input and output encodings.\n\n12. Why does the community need a new structured text design?\n\n    The existing structured text designs are deficient, for the\n    reasons given in \"Rationale\" above.  reStructuredText aims to be a\n    complete markup syntax, within the limitations of the \"readable\n    plaintext\" medium.\n\n13. What is wrong with existing documentation methodologies?\n\n    What existing methodologies?  For Python docstrings, there is\n    **no** official standard markup format, let alone a documentation\n    methodology akin to JavaDoc.  The question of methodology is at a\n    much higher level than syntax (which this PEP addresses).  It is\n    potentially much more controversial and difficult to resolve, and\n    is intentionally left out of this discussion.\n\n\nReferences & Footnotes\n======================\n\n..

An element may contain any other\nelements immediately below it in the diagram.  Notes are written in\nsquare brackets.  Element types in parentheses indicate recursive or\none-to-many relationships; sections may contain (sub)sections, tables\ncontain further body elements, etc. ::\n\n  +--------------------------------------------------------------------+\n  | document  [may begin with a title, subtitle, decoration, docinfo]  |\n  |                             +--------------------------------------+\n  |                             | sections  [each begins with a title] |\n  +-----------------------------+-------------------------+------------+\n  | [body elements:]                                      | (sections) |\n  |         | - literal | - lists  |       | - hyperlink  +------------+\n  |         |   blocks  | - tables |       |   targets    |\n  | para-   | - doctest | - block  | foot- | - sub. defs  |\n  | graphs  |   blocks  |   quotes | notes | - comments   |\n  +---------+-----------+----------+-------+--------------+\n  | [text]+ | [text]    | (body elements)  | [text]       |\n  | (inline +-----------+------------------+--------------+\n  | markup) |\n  +---------+\n\nThe Docutils document model uses a simple, recursive model for section\nstructure.  A document_ node may contain body elements and section_\nelements.  Sections in turn may contain body elements and sections.\nThe level (depth) of a section element is determined from its physical\nnesting level; unlike other document models (``<h1>`` in HTML_,\n``<sect1>`` in DocBook_, ``<div1>`` in XMLSpec_) the level is not\nincorporated into the element name.\n\nThe Docutils document model uses strict element content models.  Every\nelement has a unique structure and semantics, but elements may be\nclassified into general categories (below).  Only elements which are\nmeant to directly contain text data have a mixed content model, where\ntext data and inline elements may be intermixed.  This is unlike the\nmuch looser HTML_ document model, where paragraphs and text data may\noccur at the same level.\n\n.. _HTML: https://www.w3.org/TR/html52/\n.. _DocBook: https://tdg.docbook.org/tdg/5.1/\n.. _XMLSpec: https://www.w3.org/XML/1998/06/xmlspec-report.htm\n\n\nStructural Elements\n===================\n\nStructural elements may only contain child elements; they do not\ndirectly contain text data.  Structural elements may contain body\nelements or further structural elements.  Structural elements can only\nbe child elements of other structural elements.\n\nCategory members: document_, section_, topic_, sidebar_\n\n\nStructural Subelements\n----------------------\n\nStructural subelements are child elements of structural elements.\nSimple structuctural subelements (title_, subtitle_) contain text\ndata; the others are compound and do not directly contain text data.\n\nCategory members: title_, subtitle_, decoration_, docinfo_, meta_,\ntransition_\n\n\nBibliographic Elements\n``````````````````````\n\nThe docinfo_ element is an optional child of document_.  It groups\nbibliographic elements together.  All bibliographic elements except\nauthors_ and field_ contain text data.  authors_ contains further\nbibliographic elements (most notably author_).  field_ contains\nfield_name_ and field_body_ body subelements.\n\nCategory members: address_, author_, authors_, contact_, copyright_,\ndate_, field_, organization_, revision_, status_, version_\n\n\nDecorative Elements\n```````````````````\n\nThe decoration_ element is also an optional child of document_.  It\ngroups together elements used to generate page headers and footers.\n\nCategory members: footer_, header_\n\n\nBody Elements\n=============\n\nBody elements are contained within structural elements and compound\nbody elements.  There are two subcategories of body elements: simple\nand compound.\n\nCategory members: admonition_, attention_, block_quote_, bullet_list_,\ncaution_, citation_, comment_, compound_, container_, danger_,\ndefinition_list_, doctest_block_, enumerated_list_, error_,\nfield_list_, figure_, footnote_, hint_, image_, important_,\nline_block_, literal_block_, note_, option_list_, paragraph_,\npending_, raw_, rubric_, substitution_definition_, system_message_,\ntable_, target_, tip_, warning_\n\n\nSimple Body Elements\n--------------------\n\nSimple body elements are empty or directly contain text data.  Those\nthat contain text data may also contain inline elements.  Such\nelements therefore have a \"mixed content model\".\n\nCategory members: comment_, doctest_block_, image_, literal_block_,\nmath_block_, paragraph_, pending_, raw_, rubric_, substitution_definition_,\ntarget_\n\n\nCompound Body Elements\n----------------------\n\nCompound body elements contain local substructure (body subelements)\nand further body elements.  They do not directly contain text data.\n\nCategory members: admonition_, attention_, block_quote_, bullet_list_,\ncaution_, citation_, compound_, container_, danger_, definition_list_,\nenumerated_list_, error_, field_list_, figure_, footnote_, hint_,\nimportant_, line_block, note_, option_list_, system_message_, table_,\ntip_, warning_\n\n\nBody Subelements\n````````````````\n\nCompound body elements contain specific subelements (e.g. bullet_list_\ncontains list_item_).  Subelements may themselves be compound elements\n(containing further child elements, like field_) or simple data\nelements (containing text data, like field_name_).  These subelements\nalways occur within specific parent elements, never at the body\nelement level (beside paragraphs, etc.).\n\nCategory members (simple): attribution_, caption_, classifier_,\ncolspec_, field_name_, label_, line_, option_argument_,\noption_string_, term_\n\nCategory members (compound): definition_, definition_list_item_,\ndescription_, entry_, field_, field_body_, legend_, list_item_,\noption_, option_group_, option_list_item_, row_, tbody_, tgroup_,\nthead_\n\n\nInline Elements\n===============\n\nInline elements directly contain text data, and may also contain\nfurther inline elements.  Inline elements are contained within simple\nbody elements.  Most inline elements have a \"mixed content model\".\n\nCategory members: abbreviation_, acronym_, citation_reference_,\nemphasis_, footnote_reference_, generated_, image_, inline_, literal_,\nmath_, problematic_, reference_, strong_, subscript_,\nsubstitution_reference_, superscript_, target_, title_reference_, raw_\n\n\n-------------------\n Element Reference\n-------------------\n\n.. contents:: :local:\n              :depth: 1\n\nEach element in the DTD (document type definition) is described in its\nown section below.  Each section contains an introduction plus the\nfollowing subsections:\n\n* Details (of element relationships and semantics):\n\n  - Category: One or more references to the element categories in\n    `Element Hierarchy`_ above.  Some elements belong to more than one\n    category.\n\n  - Analogues: Describes analogous elements in well-known document\n    models such as HTML_ or DocBook_.  Lists similarities and\n    differences.\n\n  - Processing: Lists formatting or rendering recommendations for the\n    element.\n\n  - Parents: A list of elements which may contain the element.\n\n  - Children: A list of elements which may occur within the element\n    followed by the formal XML content model from the `Docutils DTD`_.\n\n  - Attributes: Describes (or refers to descriptions of) the possible\n    values and semantics of each attribute.\n\n  - Parameter Entities: Lists the parameter entities which directly or\n    indirectly include the element.\n\n* Examples: reStructuredText_ examples are shown along with\n  fragments of the document trees resulting from parsing.\n  _`Pseudo-XML` is used for the results of parsing and processing.\n  Pseudo-XML is a representation of XML where nesting is indicated by\n  indentation and end-tags are not shown.  Some of the precision of\n  real XML is given up in exchange for easier readability.  For\n  example, the following are equivalent:\n\n  - Real XML::\n\n        <document>\n        <section ids=\"a-title\" names=\"a title\">\n        <title>A Title</title>\n        <paragraph>A paragraph.</paragraph>\n        </section>\n        </document>\n\n  - Pseudo-XML::\n\n        <document>\n            <section ids=\"a-title\" names=\"a title\">\n                <title>\n                    A Title\n                <paragraph>\n                    A paragraph.\n\n--------------------\n\nMany of the element reference sections below are marked \"_`to be\ncompleted`\".

It corresponds to the\nfront matter of a book, such as the title page and copyright page.\n\nSee also the meta_ element (for \"hidden\" meta-data).\n\nDetails\n-------\n\n:Category:\n    `Structural Subelements`_\n\n:Analogues:\n    ``docinfo`` is analogous to DocBook \"info\" elements (\"bookinfo\"\n    etc.).  There are no directly analogous HTML elements; the \"meta\"\n    element carries some of the same information, albeit invisibly.\n\n:Processing:\n    The ``docinfo`` element may be rendered as a two-column table or\n    in other styles.  It may even be invisible or omitted from the\n    processed output.  Meta-data may be extracted from ``docinfo``\n    children; for example, HTML ``<meta>`` tags may be constructed.\n\n    When Docutils_ transforms a reStructuredText_ field_list_ into a\n    ``docinfo`` element (see the examples below), RCS/CVS keywords are\n    normally stripped from simple (one paragraph) field bodies.

Also\nsee the individual examples for the various `bibliographic elements`_.\n\n\n``doctest_block``\n=================\n\nThe ``doctest_block`` element is a Python-specific variant of\nliteral_block_.  It is a block of text where line breaks and\nwhitespace are significant and must be preserved.  ``doctest_block``\nelements are used for interactive Python interpreter sessions, which\nare distinguished by their input prompt: ``>>>``.  They are meant to\nillustrate usage by example, and provide an elegant and powerful\ntesting environment via the `doctest module`_ in the Python standard\nlibrary.\n\n.. _doctest module:\n   https://docs.python.org/3/library/doctest.html\n\n\nDetails\n-------\n\n:Category:\n    `Simple Body Elements`_\n\n:Analogues:\n    ``doctest_block`` is analogous to the HTML \"pre\" element and to\n    the DocBook \"programlisting\" and \"screen\" elements.\n\n:Processing:\n    As with literal_block_, ``doctest_block`` elements are typically\n    rendered in a monospaced typeface.  It is crucial that all\n    whitespace and line breaks are preserved in the rendered form.\n\n:Parents:\n    All elements employing the `%body.elements;`_ or\n    `%structure.model;`_ parameter entities in their content models\n    may contain ``doctest_block``.\n\n:Children:\n    ``doctest_block`` elements may contain text data plus `inline\n    elements`_.\n\n    .. parsed-literal::\n\n       `%text.model;`_\n\n:Attributes:\n    The ``doctest_block`` element contains the `common attributes`_\n    plus `xml:space`_.\n\n:Parameter Entities:\n    The `%body.elements;`_ parameter entity directly includes\n    ``doctest_block``.

It encloses the entire document\ntree.  It is the starting point for a document.\n\n\nDetails\n-------\n\n:Category:\n    `Structural Elements`_\n\n:Analogues:\n    ``document`` is analogous to the HTML \"html\" element and to\n    several DocBook elements such as \"book\".\n\n:Parents:\n    The ``document`` element has no parents.\n\n:Children:\n    ``document`` elements may contain `structural subelements`_,\n    `structural elements`_, and `body elements`_.\n\n    .. parsed-literal::\n\n        ( (title_, subtitle_?)?,\n          decoration_?,\n          (docinfo_, transition_?)?,\n          `%structure.model;`_ )\n\nDepending on the source of the data and the stage of processing, the\n\"document\" may not initially contain a \"title\".  A document title is\nnot directly representable in reStructuredText_.  Instead, a lone\ntop-level section may have its title promoted to become the document\ntitle_, and similarly for a lone second-level (sub)section's title to\nbecome the document subtitle_.\n\nThe contents of \"decoration_\" may be specified in a document,\nconstructed programmatically, or both.  The \"docinfo_\" may be\ntransformed from an initial field_list_.\n\nSee the `%structure.model;`_ parameter entity for details of the body\nof a ``document``.\n\n:Attributes:\n    The ``document`` element contains the `common attributes`_ (ids_,\n    names_, dupnames_, source_, and classes_), plus an optional\n    `title attribute`_ which stores the document title metadata.\n\nExamples\n--------\n\nreStructuredText_ source::\n\n    A Title\n    =======\n\n    A paragraph.\n\nComplete pseudo-XML_ result from simple parsing::\n\n    <document>\n        <section ids=\"a-title\" names=\"a title\">\n            <title>\n                A Title\n            <paragraph>\n                A paragraph.\n\nAfter applying transforms, the section title is promoted to become the\ndocument title::\n\n    <document ids=\"a-title\" names=\"a title\">\n        <title>\n            A Title\n        <paragraph>\n            A paragraph.\n\n\n``emphasis``\n============\n\n`To be completed`_.\n\n\n``entry``\n=========\n\n`To be completed`_.\n\n\n``enumerated_list``\n===================\n\nThe ``enumerated_list`` element contains list_item_ elements which are\nuniformly marked with enumerator labels.\n\n\nDetails\n-------\n\n:Category:\n    `Compound Body Elements`_\n\n:Analogues:\n    ``enumerated_list`` is analogous to the HTML \"ol\" element and to\n    the DocBook \"orderedlist\" element.\n\n:Processing:\n    Each list item should begin a new vertical block, prefaced by a\n    enumeration marker (such as \"1.\").\n\n:Parents:\n    All elements employing the `%body.elements;`_ or\n    `%structure.model;`_ parameter entities in their content models\n    may contain ``enumerated_list``.\n\n:Children:\n    ``enumerated_list`` elements contain one or more list_item_\n    elements::\n\n        (list_item+)\n\n:Attributes:\n    The ``enumerated_list`` element contains the `common attributes`_\n    plus enumtype_,\n    prefix_, suffix_, and start_.\n\n    ``enumtype`` is used to record the intended enumeration sequence,\n    one of \"arabic\" (1, 2, 3, ...), \"loweralpha\" (a, b, c, ..., z),\n    \"upperalpha\" (A, B, C, ..., Z), \"lowerroman\" (i, ii, iii, iv, ...,\n    mmmmcmxcix [4999]), or \"upperroman\" (I, II, III, IV, ...,\n    MMMMCMXCIX [4999]).\n\n    ``prefix`` stores the formatting characters used before the\n    enumerator.  In documents originating from reStructuredText_ data,\n    it will contain either \"\" (empty string) or \"(\" (left\n    parenthesis).  It may or may not affect processing.\n\n    ``suffix`` stores the formatting characters used after the\n    enumerator.  In documents originating from reStructuredText_ data,\n    it will contain either \".\" (period) or \")\" (right parenthesis).\n    Depending on the capabilities of the output format, this attribute\n    may or may not affect processing.\n\n    ``start`` contains the ordinal value of the first item in the\n    list, in decimal.  For lists beginning at value 1 (\"1\", \"a\", \"A\",\n    \"i\", or \"I\"), this attribute may be omitted.\n\n:Parameter Entities:\n    The `%body.elements;`_ parameter entity directly includes\n    ``enumerated_list``.

Whitespace inside a\nname is backslash escaped.\nEach name in the list must be unique; if there are name conflicts\n(two or more elements want to the same name), the contents will be\ntransferred to the `dupnames`_ attribute on the duplicate elements.\nAn element may have at most one of the ``names`` or ``dupnames``\nattributes, but not both.\n\n`Reference names`_ are identifiers assigned in the markup. They\noriginate from `internal hyperlink targets`_, a directive's `name\noption`_, or the element's title or content and are used for\ninternal cross-references (cf. refname_).\n\n``names`` is one of the `common attributes`_, shared by all\nDocutils elements.\n\n.. _normalized:\n   rst/restructuredtext.html#normalized-reference-names\n.. _internal hyperlink targets:\n   rst/restructuredtext.html#internal-hyperlink-targets\n.. _name option: rst/directives.html#name\n\n\n``prefix``\n==========\n\nAttribute type: `CDATA`_.

From Webster's Revised Unabridged Dictionary (1913) [web1913]:\n   Admonition\n      Gentle or friendly reproof; counseling against a fault or\n      error; expression of authoritative advice; friendly caution\n      or warning.\n\n      Syn: {Admonition}, {Reprehension}, {Reproof}.\n\n      Usage: Admonition is prospective, and relates to moral delinquencies;\n             its object is to prevent further transgression.\n\n.. _attention:\n.. _caution:\n.. _danger:\n.. _error:\n.. _hint:\n.. _important:\n.. _note:\n.. _tip:\n.. _warning:\n\nSpecific Admonitions\n====================\n\n:Directive Types: \"attention\", \"caution\", \"danger\", \"error\", \"hint\",\n                  \"important\", \"note\", \"tip\", \"warning\", \"admonition\"\n:Doctree Elements: attention, caution, danger, error, hint, important,\n                   note, tip, warning, admonition_, title_\n:Directive Arguments: None.\n:Directive Options: class_, name_\n:Directive Content: Interpreted as body elements.\n\nAdmonitions are specially marked \"topics\" that can appear anywhere an\nordinary body element can.  They contain arbitrary body elements.\nTypically, an admonition is rendered as an offset block in a document,\nsometimes outlined or shaded, with a title matching the admonition\ntype.  For example::\n\n    .. DANGER::\n       Beware killer rabbits!\n\nThis directive might be rendered something like this::\n\n    +------------------------+\n    |        !DANGER!        |\n    |                        |\n    | Beware killer rabbits! |\n    +------------------------+\n\nThe following admonition directives have been implemented:\n\n- attention\n- caution\n- danger\n- error\n- hint\n- important\n- note\n- tip\n- warning\n\nAny text immediately following the directive indicator (on the same\nline and/or indented on following lines) is interpreted as a directive\nblock and is parsed for normal body elements.  For example, the\nfollowing \"note\" admonition directive contains one paragraph and a\nbullet list consisting of two list items::\n\n    .. note:: This is a note admonition.\n       This is the second line of the first paragraph.\n\n       - The note contains all indented body elements\n         following.\n       - It includes this bullet list.\n\n\nGeneric Admonition\n==================\n\n:Directive Type: \"admonition\"\n:Doctree Elements: admonition_, title_\n:Directive Arguments: One, required (admonition title)\n:Directive Options: class_, name_\n:Directive Content: Interpreted as body elements.\n\nThis is a generic, titled admonition.  The title may be anything the\nauthor desires.\n\nThe author-supplied title is also used as a `\"classes\"`_ attribute value\nafter being converted into a valid identifier form (down-cased;\nnon-alphanumeric characters converted to single hyphens; \"admonition-\"\nprefixed).  For example, this admonition::\n\n    .. admonition:: And, by the way...\n\n       You can make up your own admonition too.\n\nbecomes the following document tree (pseudo-XML)::\n\n    <document source=\"test data\">\n        <admonition classes=\"admonition-and-by-the-way\">\n            <title>\n                And, by the way...\n            <paragraph>\n                You can make up your own admonition too.\n\nThe class_ option overrides the computed `\"classes\"`_ attribute\nvalue.\n\n\n--------\n Images\n--------\n\nThere are two image directives: \"image\" and \"figure\".\n\n.. attention:: \n\n  It is up to the author to ensure compatibility of the image data format\n  with the output format or user agent (LaTeX engine, `HTML browser`__).\n  The following, non exhaustive table provides an overview:\n  \n  =========== ====== ====== ===== ===== ===== ===== ===== ===== ===== =====\n  ..          vector image  raster image                  moving image [#]_\n  ----------- ------------- ----------------------------- -----------------\n  ..

As with hyperlink targets, the image URI may begin on the\nsame line as the explicit markup start and target name, or it may\nbegin in an indented text block immediately following, with no\nintervening blank lines.  If there are multiple lines in the link\nblock, they are stripped of leading and trailing whitespace and joined\ntogether.\n\nOptionally, the image link block may contain a flat field list, the\n_`image options`.  For example::\n\n    .. image:: picture.jpeg\n       :height: 100px\n       :width: 200 px\n       :scale: 50 %\n       :alt: alternate text\n       :align: right\n\nThe following options are recognized:\n\n``alt`` : text\n    Alternate text: a short description of the image, displayed by\n    applications that cannot display images, or spoken by applications\n    for visually impaired users.\n\n``height`` : `length`_\n    The desired height of the image.\n    Used to reserve space or scale the image vertically.  When the \"scale\"\n    option is also specified, they are combined.  For example, a height of\n    200px and a scale of 50 is equivalent to a height of 100px with no scale.\n\n``width`` : `length`_ or `percentage`_ of the current line width\n    The width of the image.\n    Used to reserve space or scale the image horizontally.  As with \"height\"\n    above, when the \"scale\" option is also specified, they are combined.\n\n``scale`` : integer percentage (the \"%\" symbol is optional)\n    The uniform scaling factor of the image.  The default is \"100 %\", i.e.\n    no scaling.\n\n    If no \"height\" or \"width\" options are specified, the `Python\n    Imaging Library` (PIL/Pillow_) may be used to determine them, if\n    it is installed and the image file is available.\n\n``align`` : \"top\", \"middle\", \"bottom\", \"left\", \"center\", or \"right\"\n    The alignment of the image, equivalent to the HTML ``<img>`` tag's\n    deprecated \"align\" attribute or the corresponding \"vertical-align\" and\n    \"text-align\" CSS properties.\n    The values \"top\", \"middle\", and \"bottom\"\n    control an image's vertical alignment (relative to the text\n    baseline); they are only useful for inline images (substitutions).\n    The values \"left\", \"center\", and \"right\" control an image's\n    horizontal alignment, allowing the image to float and have the\n    text flow around it.  The specific behavior depends upon the\n    browser or rendering software used.\n\n``target`` : text (URI or reference name)\n    Makes the image into a hyperlink reference (\"clickable\").  The\n    option argument may be a URI (relative or absolute), or a\n    `reference name`_ with underscore suffix (e.g. ```a name`_``).\n\nand the common options class_ and name_.\n\n\nFigure\n======\n\n:Directive Type: \"figure\"\n:Doctree Elements: figure_, image_, caption_, legend_\n:Directive Arguments: One, required (image URI).\n:Directive Options: Possible (see below).\n:Directive Content: Interpreted as the figure caption and an optional\n                    legend.\n\nA \"figure\" consists of image_ data (including `image options`_), an optional\ncaption (a single paragraph), and an optional legend (arbitrary body\nelements). For page-based output media, figures might float to a different\nposition if this helps the page layout.\n::\n\n    .. figure:: picture.png\n       :scale: 50 %\n       :alt: map to buried treasure\n\n       This is the caption of the figure (a simple paragraph).\n\n       The legend consists of all elements after the caption.  In this\n       case, the legend consists of this paragraph and the following\n       table:\n\n       +-----------------------+-----------------------+\n       | Symbol                | Meaning               |\n       +=======================+=======================+\n       | .. image:: tent.png   | Campground            |\n       +-----------------------+-----------------------+\n       | .. image:: waves.png  | Lake                  |\n       +-----------------------+-----------------------+\n       | .. image:: peak.png   | Mountain              |\n       +-----------------------+-----------------------+\n\nThere must be blank lines before the caption paragraph and before the\nlegend.  To specify a legend without a caption, use an empty comment\n(\"..\") in place of the caption.\n\nThe \"figure\" directive supports all of the options of the \"image\"\ndirective (see `image options`_ above). These options (except\n\"align\") are passed on to the contained image.\n\n``align`` : \"left\", \"center\", or \"right\"\n    The horizontal alignment of the figure, allowing the image to\n    float and have the text flow around it.  The specific behavior\n    depends upon the browser or rendering software used.\n\nIn addition, the following options are recognized:\n\n``figwidth`` : \"image\", length_, or percentage_ of current line width\n    The width of the figure.\n    Limits the horizontal space used by the figure.\n    A special value of \"image\" is allowed, in which case the\n    included image's actual width is used (requires the `Python Imaging\n    Library`_). If the image file is not found or the required software is\n    unavailable, this option is ignored.\n\n    Sets the \"width\" attribute of the \"figure\" doctree element.\n\n    This option does not scale the included image; use the \"width\"\n    `image`_ option for that. ::\n\n        +---------------------------+\n        |        figure             |\n        |                           |\n        |<------ figwidth --------->|\n        |                           |\n        |  +---------------------+  |\n        |  |     image           |  |\n        |  |                     |  |\n        |  |<--- width --------->|  |\n        |  +---------------------+  |\n        |                           |\n        |The figure's caption should|\n        |wrap at this width.        |\n        +---------------------------+\n\n``figclass`` : text\n    Set a `\"classes\"`_ attribute value on the figure element.  See the\n    class_ directive below.\n\n.. _Python Imaging Library:\n.. _Pillow: https://pypi.org/project/Pillow/\n\n\n---------------\n Body Elements\n---------------\n\nTopic\n=====\n\n:Directive Type: \"topic\"\n:Doctree Element: topic_\n:Directive Arguments: One, required (topic title).\n:Directive Options: class_, name_\n:Directive Content: Interpreted as the topic body.\n\nA topic is like a block quote with a title, or a self-contained\nsection with no subsections.  Use the \"topic\" directive to indicate a\nself-contained idea that is separate from the flow of the document.\nTopics may occur anywhere a section or transition may occur.  Body\nelements and topics may not contain nested topics.\n\nThe directive's sole argument is interpreted as the topic title; the\nnext line must be blank.  All subsequent lines make up the topic body,\ninterpreted as body elements.  For example::\n\n    .. topic:: Topic Title\n\n        Subsequent indented lines comprise\n        the body of the topic, and are\n        interpreted as body elements.\n\n\nSidebar\n=======\n\n:Directive Type: \"sidebar\"\n:Doctree Element: sidebar_\n:Directive Arguments: One, optional (sidebar title).\n:Directive Options: Possible (see below).\n:Directive Content: Interpreted as the sidebar body.\n\nSidebars are like miniature, parallel documents that occur inside\nother documents, providing related or reference material.  A sidebar\nis typically offset by a border and \"floats\" to the side of the page;\nthe document's main text may flow around it.  Sidebars can also be\nlikened to super-footnotes; their content is outside of the flow of\nthe document's main text.\n\nSidebars may occur anywhere a section or transition may occur.  Body\nelements (including sidebars) may not contain nested sidebars.\n\nThe directive's sole argument is interpreted as the sidebar title,\nwhich may be followed by a subtitle option (see below); the next line\nmust be blank.  All subsequent lines make up the sidebar body,\ninterpreted as body elements.  For example::\n\n    .. sidebar:: Optional Sidebar Title\n       :subtitle: Optional Sidebar Subtitle\n\n       Subsequent indented lines comprise\n       the body of the sidebar, and are\n       interpreted as body elements.\n\nThe following options are recognized:\n\n``subtitle`` : text\n    The sidebar's subtitle.\n\nand the common options class_ and name_.\n\n\nLine Block\n==========\n\n.. admonition:: Deprecated\n\n   The \"line-block\" directive is deprecated.  Use the `line block\n   syntax`_ instead.\n\n   .. _line block syntax: restructuredtext.html#line-blocks\n\n:Directive Type: \"line-block\"\n:Doctree Element: line_block_\n:Directive Arguments: None.\n:Directive Options: class_, name_\n:Directive Content: Becomes the body of the line block.\n\nThe \"line-block\" directive constructs an element where line breaks and\ninitial indentation is significant and inline markup is supported.  It\nis equivalent to a `parsed literal block`_ with different rendering:\ntypically in an ordinary serif typeface instead of a\ntypewriter/monospaced face, and not automatically indented.  (Have the\nline-block directive begin a block quote to get an indented line\nblock.)  Line blocks are useful for address blocks and verse (poetry,\nsong lyrics), where the structure of lines is significant.  For\nexample, here's a classic::\n\n    \"To Ma Own Beloved Lassie: A Poem on her 17th Birthday\", by\n    Ewan McTeagle (for Lassie O'Shea):\n\n        .. line-block::\n\n            Lend us a couple of bob till Thursday.\n            I'm absolutely skint.\n            But I'm expecting a postal order and I can pay you back\n                as soon as it comes.\n            Love, Ewan.\n\n\n\n.. _parsed-literal:\n\nParsed Literal Block\n====================\n\n:Directive Type: \"parsed-literal\"\n:Doctree Element: literal_block_\n:Directive Arguments: None.\n:Directive Options: class_, name_\n:Directive Content: Becomes the body of the literal block.\n\nUnlike an ordinary literal block, the \"parsed-literal\" directive\nconstructs a literal block where the text is parsed for inline markup.\nIt is equivalent to a `line block`_ with different rendering:\ntypically in a typewriter/monospaced typeface, like an ordinary\nliteral block.  Parsed literal blocks are useful for adding hyperlinks\nto code examples.\n\nHowever, care must be taken with the text, because inline markup is\nrecognized and there is no protection from parsing.  Backslash-escapes\nmay be necessary to prevent unintended parsing.  And because the\nmarkup characters are removed by the parser, care must also be taken\nwith vertical alignment.  Parsed \"ASCII art\" is tricky, and extra\nwhitespace may be necessary.\n\nFor example, all the element names in this content model are links::\n\n    .. parsed-literal::\n\n       ( (title_, subtitle_?)?,\n         decoration_?,\n         (docinfo_, transition_?)?,\n         `%structure.model;`_ )\n\nCode\n====\n\n:Directive Type: \"code\"\n:Doctree Element: literal_block_, `inline elements`_\n:Directive Arguments: One, optional (formal language).\n:Directive Options: name, class, number-lines.\n:Directive Content: Becomes the body of the literal block.\n:Configuration Setting: syntax_highlight_.\n\nThe \"code\" directive constructs a literal block. If the code language is\nspecified, the content is parsed by the Pygments_ syntax highlighter and\ntokens are stored in nested `inline elements`_ with class arguments\naccording to their syntactic category. The actual highlighting requires\na style-sheet (e.g. one `generated by Pygments`__, see the\n`sandbox/stylesheets`__ for examples).\n\nThe parsing can be turned off with the syntax_highlight_ configuration\nsetting and command line option or by specifying the language as class_\noption instead of directive argument. This also avoids warnings\nwhen Pygments_ is not installed or the language is not in the\n`supported languages and markup formats`_.\n\nFor inline code, use the `\"code\" role`_.\n\n__ https://pygments.org/docs/cmdline/#generating-styles\n__ https://docutils.sourceforge.io/sandbox/stylesheets/\n.. _Pygments: https://pygments.org/\n.. _syntax_highlight: ../../user/config.html#syntax-highlight\n.. _supported languages and markup formats: https://pygments.org/languages/\n.. _\"code\" role: roles.html#code\n\n\nThe following options are recognized:\n\n``number-lines`` : [integer] (start line number)\n    Precede every line with a line number.\n    The optional argument is the number of the first line (default 1).\n\nand the common options class_ and name_.\n\nExample::\n  The content of the following directive ::\n\n    .. code:: python\n\n      def my_function():\n          \"just a test\"\n          print 8/2\n\n  is parsed and marked up as Python source code.\n\n\nMath\n====\n\n:Directive Type: \"math\"\n:Doctree Element: math_block_\n:Directive Arguments: None.\n:Directive Options: class_, name_\n:Directive Content: Becomes the body of the math block.\n                    (Content blocks separated by a blank line are put in\n                    adjacent math blocks.)\n:Configuration Setting: math_output_\n\nThe \"math\" directive inserts blocks with mathematical content\n(display formulas, equations) into the document. The input format is\n`LaTeX math syntax`_ with support for Unicode symbols, for example::\n\n  .. math::\n\n    α_t(i) = P(O_1, O_2, … O_t, q_t = S_i λ)\n\nSupport is limited to a subset of *LaTeX math* by the conversion\nrequired for many output formats.  For HTML, the `math_output`_\nconfiguration setting (or the corresponding ``--math-output``\ncommand line option) select between alternative output formats with\ndifferent subsets of supported elements. If a writer does not\nsupport math typesetting, the content is inserted verbatim.\n\nFor inline formulas, use the `\"math\" role`_.\n\n.. _LaTeX math syntax: ../../ref/rst/mathematics.html\n.. _\"math\" role: roles.html#math\n.. _math_output: ../../user/config.html#math-output\n\n\nRubric\n======\n\n:Directive Type: \"rubric\"\n:Doctree Element: rubric_\n:Directive Arguments: One, required (rubric text).\n:Directive Options: class_, name_\n:Directive Content: None.\n\n..\n\n     rubric n. 1. a title, heading, or the like, in a manuscript,\n     book, statute, etc., written or printed in red or otherwise\n     distinguished from the rest of the text. ...\n\n     -- Random House Webster's College Dictionary, 1991\n\nThe \"rubric\" directive inserts a \"rubric\" element into the document\ntree.  A rubric is like an informal heading that doesn't correspond to\nthe document's structure.\n\n\nEpigraph\n========\n\n:Directive Type: \"epigraph\"\n:Doctree Element: block_quote_\n:Directive Arguments: None.\n:Directive Options: None.\n:Directive Content: Interpreted as the body of the block quote.\n\nAn epigraph is an apposite (suitable, apt, or pertinent) short\ninscription, often a quotation or poem, at the beginning of a document\nor section.\n\nThe \"epigraph\" directive produces an \"epigraph\"-class block quote.\nFor example, this input::\n\n     .. epigraph::\n\n        No matter where you go, there you are.\n\n        -- Buckaroo Banzai\n\nbecomes this document tree fragment::\n\n    <block_quote classes=\"epigraph\">\n        <paragraph>\n            No matter where you go, there you are.\n        <attribution>\n            Buckaroo Banzai\n\n\nHighlights\n==========\n\n:Directive Type: \"highlights\"\n:Doctree Element: block_quote_\n:Directive Arguments: None.\n:Directive Options: None.\n:Directive Content: Interpreted as the body of the block quote.\n\nHighlights summarize the main points of a document or section, often\nconsisting of a list.\n\nThe \"highlights\" directive produces a \"highlights\"-class block quote.\nSee Epigraph_ above for an analogous example.\n\n\nPull-Quote\n==========\n\n:Directive Type: \"pull-quote\"\n:Doctree Element: block_quote_\n:Directive Arguments: None.\n:Directive Options: None.\n:Directive Content: Interpreted as the body of the block quote.\n\nA pull-quote is a small selection of text \"pulled out and quoted\",\ntypically in a larger typeface.  Pull-quotes are used to attract\nattention, especially in long articles.\n\nThe \"pull-quote\" directive produces a \"pull-quote\"-class block quote.\nSee Epigraph_ above for an analogous example.\n\n\nCompound Paragraph\n==================\n\n:Directive Type: \"compound\"\n:Doctree Element: compound_\n:Directive Arguments: None.\n:Directive Options: class_, name_\n:Directive Content: Interpreted as body elements.\n\nThe \"compound\" directive is used to create a compound paragraph, which\nis a single logical paragraph containing multiple physical body\nelements such as simple paragraphs, literal blocks, tables, lists,\netc., instead of directly containing text and inline elements.  For\nexample::\n\n    .. compound::\n\n       The 'rm' command is very dangerous.  If you are logged\n       in as root and enter ::\n\n           cd /\n           rm -rf *\n\n       you will erase the entire contents of your file system.\n\nIn the example above, a literal block is \"embedded\" within a sentence\nthat begins in one physical paragraph and ends in another.\n\n.. note::\n\n   The \"compound\" directive is *not* a generic block-level container\n   like HTML's ``<div>`` element.  Do not use it only to group a\n   sequence of elements, or you may get unexpected results.\n\n   If you need a generic block-level container, please use the\n   container_ directive, described below.\n\nCompound paragraphs are typically rendered as multiple distinct text\nblocks, with the possibility of variations to emphasize their logical\nunity:\n\n* If paragraphs are rendered with a first-line indent, only the first\n  physical paragraph of a compound paragraph should have that indent\n  -- second and further physical paragraphs should omit the indents;\n* vertical spacing between physical elements may be reduced;\n* and so on.\n\n\nContainer\n=========\n\n:Directive Type: \"container\"\n:Doctree Element: `container <container element_>`__\n:Directive Arguments: One or more, optional (class names).\n:Directive Options: name_\n:Directive Content: Interpreted as body elements.\n\nThe \"container\" directive surrounds its contents (arbitrary body\nelements) with a generic block-level \"container\" element.  Combined\nwith the optional \"classes_\" attribute argument(s), this is an\nextension mechanism for users & applications.  For example::\n\n    .. container:: custom\n\n       This paragraph might be rendered in a custom way.\n\nParsing the above results in the following pseudo-XML::\n\n    <container classes=\"custom\">\n        <paragraph>\n            This paragraph might be rendered in a custom way.\n\nThe \"container\" directive is the equivalent of HTML's ``<div>``\nelement.  It may be used to group a sequence of elements for user- or\napplication-specific purposes.\n\n\n\n--------\n Tables\n--------\n\nFormal tables need more structure than the reStructuredText syntax\nsupplies.  Tables may be given titles with the table_ directive.\nSometimes reStructuredText tables are inconvenient to write, or table\ndata in a standard format is readily available.

They can be disabled with the\n   \"file_insertion_enabled_\" runtime setting.\n\nThe \"csv-table\" directive is used to create a table from CSV\n(comma-separated values) data.  CSV is a common data format generated\nby spreadsheet applications and commercial databases.  The data may be\ninternal (an integral part of the document) or external (a separate\nfile).\n\n* Block markup and inline markup within cells is supported.

May be specified as a Unicode\n    code point; see the unicode_ directive for syntax details.  Used\n    when the delimiter is used in an unquoted field, or when quote\n    characters are used within a field.  The default is to double-up\n    the character, e.g. \"He said, \"\"Hi!\"\"\"\n\n    ..

Topics, and therefore tables of contents, may occur anywhere\na section or transition may occur.  Body elements and topics may not\ncontain tables of contents.\n\nHere's the directive in its simplest form::\n\n    .. contents::\n\nLanguage-dependent boilerplate text will be used for the title.  The\nEnglish default title text is \"Contents\".\n\nAn explicit title may be specified::\n\n    .. contents:: Table of Contents\n\nThe title may span lines, although it is not recommended::\n\n    .. contents:: Here's a very long Table of\n       Contents title\n\nOptions may be specified for the directive, using a field list::\n\n    .. contents:: Table of Contents\n       :depth: 2\n\nIf the default title is to be used, the options field list may begin\non the same line as the directive marker::\n\n    .. contents:: :depth: 2\n\nThe following options are recognized:\n\n``depth`` : integer\n    The number of section levels that are collected in the table of\n    contents.  The default is unlimited depth.\n\n``local`` : flag (empty)\n    Generate a local table of contents.  Entries will only include\n    subsections of the section in which the directive is given.  If no\n    explicit title is given, the table of contents will not be titled.\n\n``backlinks`` : \"entry\" or \"top\" or \"none\"\n    Generate links from section headers back to the table of contents\n    entries, the table of contents itself, or generate no back-links.\n\n``class`` : text\n    Set a `\"classes\"`_ attribute value on the topic element.  See the\n    class_ directive below.\n\n\n.. _sectnum:\n.. _section-numbering:\n\nAutomatic Section Numbering\n===========================\n\n:Directive Type: \"sectnum\" or \"section-numbering\" (synonyms)\n:Doctree Elements: pending_, generated_\n:Directive Arguments: None.\n:Directive Options: Possible (see below).\n:Directive Content: None.\n:Configuration Setting: sectnum_xform_\n\nThe \"sectnum\" (or \"section-numbering\") directive automatically numbers\nsections and subsections in a document (if not disabled by the\n``--no-section-numbering`` command line option or the `sectnum_xform`_\nconfiguration setting).\n\nSection numbers are of the \"multiple enumeration\" form, where each\nlevel has a number, separated by periods.  For example, the title of section\n1, subsection 2, subsubsection 3 would have \"1.2.3\" prefixed.\n\nThe \"sectnum\" directive does its work in two passes: the initial parse\nand a transform.  During the initial parse, a \"pending\" element is\ngenerated which acts as a placeholder, storing any options internally.\nAt a later stage in the processing, the \"pending\" element triggers a\ntransform, which adds section numbers to titles.  Section numbers are\nenclosed in a \"generated\" element, and titles have their \"auto\"\nattribute set to \"1\".\n\nThe following options are recognized:\n\n``depth`` : integer\n    The number of section levels that are numbered by this directive.\n    The default is unlimited depth.\n\n``prefix`` : string\n    An arbitrary string that is prefixed to the automatically\n    generated section numbers.  It may be something like \"3.2.\", which\n    will produce \"3.2.1\", \"3.2.2\", \"3.2.2.1\", and so on.  Note that\n    any separating punctuation (in the example, a period, \".\") must be\n    explicitly provided.  The default is no prefix.\n\n``suffix`` : string\n    An arbitrary string that is appended to the automatically\n    generated section numbers.  The default is no suffix.\n\n``start`` : integer\n    The value that will be used for the first section number.\n    Combined with ``prefix``, this may be used to force the right\n    numbering for a document split over several source files.  The\n    default is 1.\n\n.. _sectnum_xform: ../../user/config.html#sectnum-xform\n\n\n.. _header:\n.. _footer:\n\nDocument Header & Footer\n========================\n\n:Directive Types: \"header\" and \"footer\"\n:Doctree Elements: decoration_, header, footer\n:Directive Arguments: None.\n:Directive Options: None.\n:Directive Content: Interpreted as body elements.\n\nThe \"header\" and \"footer\" directives create document decorations,\nuseful for page navigation, notes, time/datestamp, etc.  For example::\n\n    .. header:: This space for rent.\n\nThis will add a paragraph to the document header, which will appear at\nthe top of the generated web page or at the top of every printed page.\n\nThese directives may be used multiple times, cumulatively.  There is\ncurrently support for only one header and footer.\n\n.. note::\n\n   While it is possible to use the \"header\" and \"footer\" directives to\n   create navigational elements for web pages, you should be aware\n   that Docutils is meant to be used for *document* processing, and\n   that a navigation bar is not typically part of a document.\n\n   Thus, you may soon find Docutils' abilities to be insufficient for\n   these purposes.  At that time, you should consider using a\n   documentation generator like Sphinx_ rather than the \"header\" and\n   \"footer\" directives.\n\n   .. _Sphinx: http://sphinx-doc.org/\n\nIn addition to the use of these directives to populate header and\nfooter content, content may also be added automatically by the\nprocessing system.  For example, if certain runtime settings are\nenabled, the document footer is populated with processing information\nsuch as a datestamp, a link to `the Docutils website`_, etc.\n\n.. _the Docutils website: https://docutils.sourceforge.io\n\n\n------------\n References\n------------\n\n.. _target-notes:\n\nTarget Footnotes\n================\n\n:Directive Type: \"target-notes\"\n:Doctree Elements: pending_, footnote_, footnote_reference_\n:Directive Arguments: None.\n:Directive Options: class_, name_\n:Directive Options: Possible (see below).\n:Directive Content: None.\n\nThe \"target-notes\" directive creates a footnote for each external\ntarget in the text, and corresponding footnote references after each\nreference.

It may be used within `substitution\ndefinitions`_ only.  For example, this directive can be used to expand\nabbreviations::\n\n    .. |reST| replace:: reStructuredText\n\n    Yes, |reST| is a long word, so I can't blame anyone for wanting to\n    abbreviate it.\n\nAs reStructuredText doesn't support nested inline markup, the only way\nto create a reference with styled text is to use substitutions with\nthe \"replace\" directive::\n\n    I recommend you try |Python|_.\n\n    .. |Python| replace:: Python, *the* best language around\n    .. _Python: https://www.python.org/\n\n\n.. _unicode:\n\nUnicode Character Codes\n=======================\n\n:Directive Type: \"unicode\"\n:Doctree Element: Text\n:Directive Arguments: One or more, required (Unicode character codes,\n                      optional text, and comments).\n:Directive Options: Possible (see below).\n:Directive Content: None.\n\nThe \"unicode\" directive converts Unicode character codes (numerical\nvalues) to characters, and may be used in `substitution definitions`_\nonly.\n\nThe arguments, separated by spaces, can be:\n\n* **character codes** as\n\n  - decimal numbers or\n\n  - hexadecimal numbers, prefixed by ``0x``, ``x``, ``\\x``, ``U+``,\n    ``u``, or ``\\u`` or as XML-style hexadecimal character entities,\n    e.g. ``&#x1a2b;``\n\n* **text**, which is used as-is.\n\nText following \" .. \" is a comment and is ignored.

It may not\n        contain section headers.\n\n        .. include:: inclusion.txt\n\nIf an included document fragment contains section structure, the title\nadornments must match those of the master document.\n\nStandard data files intended for inclusion in reStructuredText\ndocuments are distributed with the Docutils source code, located in\nthe \"docutils\" package in the ``docutils/parsers/rst/include``\ndirectory.  To access these files, use the special syntax for standard\n\"include\" data files, angle brackets around the file name::\n\n    .. include:: <isonum.txt>\n\nThe current set of standard \"include\" data files consists of sets of\nsubstitution definitions.  See `reStructuredText Standard Definition\nFiles`__ for details.\n\n__ definitions.html\n\nThe following options are recognized:\n\n``start-line`` : integer\n    Only the content starting from this line will be included.\n    (As usual in Python, the first line has index 0 and negative values\n    count from the end.)\n\n``end-line`` : integer\n    Only the content up to (but excluding) this line will be included.\n\n``start-after`` : text to find in the external data file\n    Only the content after the first occurrence of the specified text\n    will be included.\n\n``end-before`` : text to find in the external data file\n    Only the content before the first occurrence of the specified text\n    (but after any ``after`` text) will be included.\n\n``parser`` :  parser name\n    Parse the included content with the specified parser.\n    (New in Docutils 0.17)\n\n``literal`` : flag (empty)\n    The entire included text is inserted into the document as a single\n    literal block.\n\n``code`` : [string] (formal language)\n    The argument and the included content are passed to\n    the code_ directive (useful for program listings).\n\n``number-lines`` : [integer] (start line number)\n    Precede every code line with a line number.\n    The optional argument is the number of the first line (default 1).\n    Works only with ``code`` or ``literal``.\n\n``encoding`` : string\n    The text encoding of the external data file.  Defaults to the\n    document's input_encoding_.\n\n    .. _input_encoding: ../../user/config.html#input-encoding\n\n``tab-width`` :  integer\n    Number of spaces for hard tab expansion.\n    A negative value prevents expansion of hard tabs. Defaults to the\n    tab_width_ configuration setting.\n\n    .. _tab_width: ../../user/config.html#tab-width\n\nWith ``code`` or ``literal`` the common options class_ and\nname_ are recognized as well.\n\nCombining ``start/end-line`` and ``start-after/end-before`` is possible. The\ntext markers will be searched in the specified lines (further limiting the\nincluded content).\n\n.. _raw-directive:\n\nRaw Data Pass-Through\n=====================\n\n:Directive Type: \"raw\"\n:Doctree Element: raw_\n:Directive Arguments: One or more, required (output format types).\n:Directive Options: Possible (see below).\n:Directive Content: Stored verbatim, uninterpreted.

It can\n   be disabled with the \"raw_enabled_\" or \"file_insertion_enabled_\"\n   runtime settings.\n\n   .. _raw_enabled: ../../user/config.html#raw-enabled\n\n.. Caution::\n\n   The \"raw\" directive is a stop-gap measure allowing the author to\n   bypass reStructuredText's markup.  It is a \"power-user\" feature\n   that should not be overused or abused.  The use of \"raw\" ties\n   documents to specific output formats and makes them less portable.\n\n   If you often need to use the \"raw\" directive or a \"raw\"-derived\n   interpreted text role, that is a sign either of overuse/abuse or\n   that functionality may be missing from reStructuredText.  Please\n   describe your situation in a message to the Docutils-users_ mailing\n   list.\n\n.. _Docutils-users: ../../user/mailing-lists.html#docutils-users\n\nThe \"raw\" directive indicates non-reStructuredText data that is to be\npassed untouched to the Writer.  The names of the output formats are\ngiven in the directive arguments.  The interpretation of the raw data\nis up to the Writer.  A Writer may ignore any raw output not matching\nits format.\n\nFor example, the following input would be passed untouched by an HTML\nwriter::\n\n    .. raw:: html\n\n       <hr width=50 size=10>\n\nA LaTeX Writer could insert the following raw content into its\noutput stream::\n\n    .. raw:: latex\n\n       \\setlength{\\parindent}{0pt}\n\nRaw data can also be read from an external file, specified in a\ndirective option.  In this case, the content block must be empty.  For\nexample::\n\n    .. raw:: html\n       :file: inclusion.html\n\nInline equivalents of the \"raw\" directive can be defined via\n`custom interpreted text roles`_ derived from the `\"raw\" role`_.\n\nThe following options are recognized:\n\n``file`` : string (newlines removed)\n    The local filesystem path of a raw data file to be included.\n\n``url`` : string (whitespace removed)\n    An Internet URL reference to a raw data file to be included.\n\n``encoding`` : string\n    The text encoding of the external raw data (file or URL).\n    Defaults to the document's encoding (if specified).\n\nand the common option class_.\n\n\n.. _\"raw\" role: roles.html#raw\n\n\n.. _classes:\n\nClass\n=====\n\n:Directive Type: \"class\"\n:Doctree Element: pending_\n:Directive Arguments: One or more, required (class names / attribute\n                      values).\n:Directive Options: None.\n:Directive Content: Optional.  If present, it is interpreted as body\n                    elements.\n\nThe \"class\" directive sets the `\"classes\"`_ attribute value on its content\nor on the first immediately following [#]_ non-comment element [#]_.\nThe directive argument consists of one or more space-separated class\nnames. The names are transformed to conform to the regular expression\n``[a-z](-?[a-z0-9]+)*`` (see `Identifier Normalization`_ below).\n\nExamples::\n\n    .. class:: special\n\n    This is a \"special\" paragraph.\n\n    .. class:: exceptional remarkable\n\n    An Exceptional Section\n    ======================\n\n    This is an ordinary paragraph.\n\n    .. class:: multiple\n\n       First paragraph.\n\n       Second paragraph.\n\nThe text above is parsed and transformed into this doctree fragment::\n\n    <paragraph classes=\"special\">\n        This is a \"special\" paragraph.\n    <section classes=\"exceptional remarkable\">\n        <title>\n            An Exceptional Section\n        <paragraph>\n            This is an ordinary paragraph.\n        <paragraph classes=\"multiple\">\n            First paragraph.\n        <paragraph classes=\"multiple\">\n            Second paragraph.\n\n\n.. [#] This is also true, if the class directive is \"nested\" at the end of\n   an indented text block, for example::\n\n       .. note:: the class values set in this directive-block do not apply to\n          the note but the next paragraph.\n\n          .. class:: special\n\n       This is a paragraph with class value \"special\".\n\n   This allows the \"classification\" of individual list items (except the\n   first, as a preceding class directive applies to the list as a whole)::\n\n       * bullet list\n\n         .. class:: classy item\n\n       * second item, with class argument\n\n.. [#] To set a \"classes\" attribute value on a block quote, the\n   \"class\" directive must be followed by an empty comment::\n\n       .. class:: highlights\n       ..\n\n           Block quote text.\n\n   Without the empty comment, the indented text would be interpreted as the\n   \"class\" directive's content, and the classes would be applied to each\n   element (paragraph, in this case) individually, instead of to the block\n   quote as a whole.\n\n\nIdentifier Normalization\n~~~~~~~~~~~~~~~~~~~~~~~~\n\nDocutils `class names`_ and `identifier keys`_ are normalized to conform\nto the regular expression \"``[a-z](-?[a-z0-9]+)*``\" by converting\n\n* alphabetic characters to lowercase,\n* accented characters to the base character,\n* non-alphanumeric characters to hyphens,\n* consecutive hyphens into one hyphen\n\nand stripping\n\n* leading hyphens and number characters, and\n* trailing hyphens.\n\nFor example ``\"Rot.Gelb&Grün:+2008\"`` becomes ``\"rot-gelb-grun-2008\"`` and\n``\"1000_Steps!\"`` becomes ``\"steps\"``.\n\n.. topic:: Rationale:\n\n    Identifier keys must be valid in all supported output formats.\n\n    For HTML 4.1 + CSS1 compatibility, identifiers should have no\n    underscores, colons, or periods.  Hyphens may be used.\n\n    - The `HTML 4.01 spec`_ defines identifiers based on SGML tokens:\n\n          ID and NAME tokens must begin with a letter ([A-Za-z]) and\n          may be followed by any number of letters, digits ([0-9]),\n          hyphens (\"-\"), underscores (\"_\"), colons (\":\"), and periods\n          (\".\").\n\n          -- https://www.w3.org/TR/html401/types.html#type-name\n\n    - The `CSS1 spec`_ defines identifiers based on the \"name\" token\n      (\"flex\" tokenizer notation below; \"latin1\" and \"escape\" 8-bit\n      characters have been replaced with XML entities)::\n\n          unicode     \\\\[0-9a-f]{1,4}\n          latin1      [&iexcl;-&yuml;]\n          escape      {unicode}|\\\\[ -~&iexcl;-&yuml;]\n          nmchar      [-A-Za-z0-9]|{latin1}|{escape}\n          name        {nmchar}+\n\n    The CSS1 rule requires underscores (\"_\"), colons (\":\"), and\n    periods (\".\") to be escaped [#]_,\n    therefore `\"classes\"`_ and `\"ids\"`_ attributes should not\n    contain these characters.  Combined with HTML4.1 requirements (the\n    first character must be a letter; no \"unicode\", \"latin1\", or\n    \"escape\" characters), this results in the regular expression\n    ``[A-Za-z][-A-Za-z0-9]*``. Docutils adds a normalization by\n    downcasing and merge of consecutive hyphens.\n\n    ..

This means that after\ndeclaring a role like this::\n\n    .. role:: custom\n\nthe document may use the new \"custom\" role::\n\n    An example of using :custom:`interpreted text`\n\nThis will be parsed into the following document tree fragment::\n\n    <paragraph>\n        An example of using\n        <inline classes=\"custom\">\n            interpreted text\n\nThe role must be declared in a document before it can be used.\n\n.. _role name:\n\nRole names are case insensitive and must conform to the rules of\nsimple `reference names`_ (but do not share a namespace with\nhyperlinks, footnotes, and citations).\n\nThe new role may be based on an existing role, specified as a second\nargument in parentheses (whitespace optional)::\n\n    .. role:: custom(emphasis)\n\n    :custom:`text`\n\nThe parsed result is as follows::\n\n    <paragraph>\n        <emphasis classes=\"custom\">\n            text\n\nA special case is the `\"raw\" role`_: derived roles enable\ninline `raw data pass-through`_, e.g.::\n\n   .. role:: raw-role(raw)\n      :format: html latex\n\n   :raw-role:`raw text`\n\nIf no base role is explicitly specified, a generic custom role is\nautomatically used.  Subsequent interpreted text will produce an\n\"inline\" element with a `\"classes\"`_ attribute, as in the first example\nabove.\n\nWith most roles, the \":class:\" option can be used to set a \"classes\"\nattribute that is different from the role name.  For example::\n\n    .. role:: custom\n       :class: special\n\n    :custom:`interpreted text`\n\nThis is the parsed result::\n\n    <paragraph>\n        <inline classes=\"special\">\n            interpreted text\n\n.. _role class:\n\nThe following option is recognized by the \"role\" directive for most\nbase roles:\n\n``class`` : text\n    Set the `\"classes\"`_ attribute value on the element produced\n    (``inline``, or element associated with a base class) when the\n    custom interpreted text role is used.  If no directive options are\n    specified, a \"class\" option with the directive argument (role\n    name) as the value is implied.  See the class_ directive above.\n\nSpecific base roles may support other options and/or directive\ncontent.  See the `reStructuredText Interpreted Text Roles`_ document\nfor details.\n\n.. _reStructuredText Interpreted Text Roles: roles.html\n\n\n.. _default-role:\n\nSetting the Default Interpreted Text Role\n=========================================\n\n:Directive Type: \"default-role\"\n:Doctree Element: None; affects subsequent parsing.\n:Directive Arguments: One, optional (new default role name).\n:Directive Options: None.\n:Directive Content: None.\n\nThe \"default-role\" directive sets the default interpreted text role,\nthe role that is used for interpreted text without an explicit role.\nFor example, after setting the default role like this::\n\n    .. default-role:: subscript\n\nany subsequent use of implicit-role interpreted text in the document\nwill use the \"subscript\" role::\n\n    An example of a `default` role.\n\nThis will be parsed into the following document tree fragment::\n\n    <paragraph>\n        An example of a\n        <subscript>\n            default\n         role.\n\nCustom roles may be used (see the \"role_\" directive above), but it\nmust have been declared in a document before it can be set as the\ndefault role.  See the `reStructuredText Interpreted Text Roles`_\ndocument for details of built-in roles.\n\nThe directive may be used without an argument to restore the initial\ndefault interpreted text role, which is application-dependent.  The\ninitial default interpreted text role of the standard reStructuredText\nparser is \"title-reference\".\n\n\nMetadata\n========\n\n:Directive Type: \"meta\"\n:Doctree Element: meta_\n:Directive Arguments: None.\n:Directive Options: None.\n:Directive Content: Must contain a flat field list.\n\nThe \"meta\" directive is used to specify metadata\\ [#]_ to be stored\nin, e.g., `HTML meta elements`_ or as `ODT file properties`_. The\nLaTeX writer passes it to the ``pdfinfo`` option of the hyperref_\npackage. If an output format does not support \"invisible\" metadata,\ncontent is silently dropped by the writer.\n\n.. note:: Data from some `bibliographic fields`_ is automatically\n   extracted and stored as metadata, too. However, Bibliographic\n   Fields are also displayed in the document's screen rendering or\n   printout.\n\n   For an \"invisible\" *document title*, see the `metadata document\n   title`_ directive below.\n\nWithin the directive block, a flat field list provides the syntax for\nmetadata.  The field name becomes the contents of the \"name\" attribute\nof the META tag, and the field body (interpreted as a single string\nwithout inline markup) becomes the contents of the \"content\"\nattribute.  For example::\n\n    .. meta::\n       :description: The reStructuredText plaintext markup language\n       :keywords: plaintext, markup language\n\nThis would be converted to the following HTML::\n\n    <meta name=\"description\"\n        content=\"The reStructuredText plaintext markup language\">\n    <meta name=\"keywords\" content=\"plaintext, markup language\">\n\nSupport for other META attributes (\"http-equiv\", \"scheme\", \"lang\",\n\"dir\") are provided through field arguments, which must be of the form\n\"attr=value\"::\n\n    .. meta::\n       :description lang=en: An amusing story\n       :description lang=fr: Une histoire amusante\n\nAnd their HTML equivalents::\n\n    <meta name=\"description\" lang=\"en\" content=\"An amusing story\">\n    <meta name=\"description\" lang=\"fr\" content=\"Une histoire amusante\">\n\nSome META tags use an \"http-equiv\" attribute instead of the \"name\"\nattribute.  To specify \"http-equiv\" META tags, simply omit the name::\n\n    .. meta::\n       :http-equiv=Content-Type: text/html; charset=ISO-8859-1\n\nHTML equivalent::\n\n    <meta http-equiv=\"Content-Type\"\n         content=\"text/html; charset=ISO-8859-1\">\n\n.. [#] \"Metadata\" is data about data, in this case data about the\n   document. Metadata is, e.g., used to describe and classify web\n   pages in the World Wide Web, in a form that is easy for search\n   engines to extract and collate.\n\n.. _HTML meta elements:\n   https://html.spec.whatwg.org/multipage/semantics.html#the-meta-element\n.. _ODT file properties:\n   https://en.wikipedia.org/wiki/OpenDocument_technical_specification#Metadata\n.. _hyperref: https://ctan.org/pkg/hyperref\n.. _bibliographic fields: restructuredtext.html#bibliographic-fields\n\n\nMetadata Document Title\n=======================\n\n:Directive Type: \"title\"\n:Doctree Element: Sets the document's `title attribute`_.\n:Directive Arguments: One, required (the title text).\n:Directive Options: None.\n:Directive Content: None.\n\nThe \"title\" directive specifies the document title as metadata, which\ndoes not become part of the document body. It overrides the\ndocument-supplied `document title`_ and the `\"title\" configuration\nsetting`_. For example, in HTML output the metadata document title\nappears in the title bar of the browser window.\n\n.. _document title: restructuredtext.html#document-title\n.. _\"title\" configuration setting: ../../user/config.html#title\n\nRestructuredtext-Test-Directive\n===============================\n\n:Directive Type: \"restructuredtext-test-directive\"\n:Doctree Element: system_warning\n:Directive Arguments: None.\n:Directive Options: None.\n:Directive Content: Interpreted as a literal block.\n\nThis directive is provided for test purposes only.  (Nobody is\nexpected to type in a name *that* long!)  It is converted into a\nlevel-1 (info) system message showing the directive data, possibly\nfollowed by a literal block containing the rest of the directive\nblock.\n\n--------------\nCommon Options\n--------------\n\nMost of the directives that generate doctree elements support the following\noptions:\n\n.. _class-option:\n.. _class:\n\n``class`` : text (space separated list of `class names`_)\n    Set a `\"classes\"`_ attribute value on the doctree element generated by\n    the directive. See also the class_ directive.\n\n    .. _name:\n\n``name`` : text\n    Add `text` to the `\"names\"`_ attribute of the doctree element generated\n    by the directive.

It is useful for inline\nprogram documentation (such as Python docstrings), for quickly\ncreating simple web pages, and for standalone documents.\nreStructuredText_ is a proposed revision and reinterpretation of the\nStructuredText_ and Setext_ lightweight markup systems.\n\nreStructuredText is designed for extensibility for specific\napplication domains.  Its parser is a component of Docutils_.\n\nThis document defines the goals_ of reStructuredText and provides a\nhistory_ of the project.  It is written using the reStructuredText\nmarkup, and therefore serves as an example of its use.  For a gentle\nintroduction to using reStructuredText, please read `A\nReStructuredText Primer`_.  The `Quick reStructuredText`_ user\nreference is also useful.  The `reStructuredText Markup\nSpecification`_ is the definitive reference.  There is also an\nanalysis of the `Problems With StructuredText`_.\n\nReStructuredText's web page is\nhttps://docutils.sourceforge.io/rst.html.\n\n.. _reStructuredText: https://docutils.sourceforge.io/rst.html\n.. _StructuredText: https://zopestructuredtext.readthedocs.org/\n.. _Setext: https://docutils.sourceforge.io/mirror/setext.html\n.. _Docutils: https://docutils.sourceforge.io/\n.. _A ReStructuredText Primer: ../../user/rst/quickstart.html\n.. _Quick reStructuredText: ../../user/rst/quickref.html\n.. _reStructuredText Markup Specification: restructuredtext.html\n.. _Problems with StructuredText: ../../dev/rst/problems.html\n\n\nGoals\n=====\n\nThe primary goal of reStructuredText_ is to define a markup syntax for\nuse in Python docstrings and other documentation domains, that is\nreadable and simple, yet powerful enough for non-trivial use.  The\nintended purpose of the reStructuredText markup is twofold:\n\n- the establishment of a set of standard conventions allowing the\n  expression of structure within plaintext, and\n\n- the conversion of such documents into useful structured data\n  formats.\n\nThe secondary goal of reStructuredText is to be accepted by the Python\ncommunity (by way of being blessed by PythonLabs and the BDFL [#]_) as\na standard for Python inline documentation (possibly one of several\nstandards, to account for taste).\n\n.. [#] Python's creator and \"Benevolent Dictator For Life\",\n   Guido van Rossum.\n\nTo clarify the primary goal, here are specific design goals, in order,\nbeginning with the most important:\n\n1. Readable.  The marked-up text must be easy to read without any\n   prior knowledge of the markup language.  It should be as easily\n   read in raw form as in processed form.\n\n2. Unobtrusive.  The markup that is used should be as simple and\n   unobtrusive as possible.  The simplicity of markup constructs\n   should be roughly proportional to their frequency of use.  The most\n   common constructs, with natural and obvious markup, should be the\n   simplest and most unobtrusive.  Less common constructs, for which\n   there is no natural or obvious markup, should be distinctive.\n\n3. Unambiguous.  The rules for markup must not be open for\n   interpretation.  For any given input, there should be one and only\n   one possible output (including error output).\n\n4. Unsurprising.  Markup constructs should not cause unexpected output\n   upon processing.  As a fallback, there must be a way to prevent\n   unwanted markup processing when a markup construct is used in a\n   non-markup context (for example, when documenting the markup syntax\n   itself).\n\n5. Intuitive.  Markup should be as obvious and easily remembered as\n   possible, for the author as well as for the reader.  Constructs\n   should take their cues from such naturally occurring sources as\n   plaintext email messages, newsgroup postings, and text\n   documentation such as README.txt files.\n\n6. Easy.  It should be easy to mark up text using any ordinary text\n   editor.\n\n7. Scalable.  The markup should be applicable regardless of the length\n   of the text.\n\n8. Powerful.  The markup should provide enough constructs to produce a\n   reasonably rich structured document.\n\n9. Language-neutral.  The markup should apply to multiple natural (as\n   well as artificial) languages, not only English.\n\n10. Extensible.  The markup should provide a simple syntax and\n    interface for adding more complex general markup, and custom\n    markup.\n\n11. Output-format-neutral.  The markup will be appropriate for\n    processing to multiple output formats, and will not be biased\n    toward any particular format.\n\nThe design goals above were used as criteria for accepting or\nrejecting syntax, or selecting between alternatives.\n\nIt is emphatically *not* the goal of reStructuredText to define\ndocstring semantics, such as docstring contents or docstring length.\nThese issues are orthogonal to the markup syntax and beyond the scope\nof this specification.\n\nAlso, it is not the goal of reStructuredText to maintain compatibility\nwith StructuredText_ or Setext_.  reStructuredText shamelessly steals\ntheir great ideas and ignores the not-so-great.\n\nAuthor's note:\n\n    Due to the nature of the problem we're trying to solve (or,\n    perhaps, due to the nature of the proposed solution), the above\n    goals unavoidably conflict.  I have tried to extract and distill\n    the wisdom accumulated over the years in the Python Doc-SIG_\n    mailing list and elsewhere, to come up with a coherent and\n    consistent set of syntax rules, and the above goals by which to\n    measure them.\n\n    There will inevitably be people who disagree with my particular\n    choices.  Some desire finer control over their markup, others\n    prefer less.  Some are concerned with very short docstrings,\n    others with full-length documents.  This specification is an\n    effort to provide a reasonably rich set of markup constructs in a\n    reasonably simple form, that should satisfy a reasonably large\n    group of reasonable people.\n\n    David Goodger (goodger@python.org), 2001-04-20\n\n.. _Doc-SIG: https://www.python.org/sigs/doc-sig/\n\n\nHistory\n=======\n\nreStructuredText_, the specification, is based on StructuredText_ and\nSetext_.  StructuredText was developed by Jim Fulton of `Zope\nCorporation`_ (formerly Digital Creations) and first released in 1996.\nIt is now released as a part of the open-source \"Z Object Publishing\nEnvironment\" (ZOPE_).  Ian Feldman's and Tony Sanders' earlier Setext_\nspecification was either an influence on StructuredText or, by their\nsimilarities, at least evidence of the correctness of this approach.\n\nI discovered StructuredText_ in late 1999 while searching for a way to\ndocument the Python modules in one of my projects.  Version 1.1 of\nStructuredText was included in Daniel Larsson's pythondoc_.  Although\nI was not able to get pythondoc to work for me, I found StructuredText\nto be almost ideal for my needs.  I joined the Python Doc-SIG_\n(Documentation Special Interest Group) mailing list and found an\nongoing discussion of the shortcomings of the StructuredText\n\"standard\".  This discussion has been going on since the inception of\nthe mailing list in 1996, and possibly predates it.\n\nI decided to modify the original module with my own extensions and\nsome suggested by the Doc-SIG members.  I soon realized that the\nmodule was not written with extension in mind, so I embarked upon a\ngeneral reworking, including adapting it to the \"re\" regular\nexpression module (the original inspiration for the name of this\nproject).  Soon after I completed the modifications, I discovered that\nStructuredText.py was up to version 1.23 in the ZOPE distribution.\nImplementing the new syntax extensions from version 1.23 proved to be\nan exercise in frustration, as the complexity of the module had become\noverwhelming.\n\nIn 2000, development on StructuredTextNG (\"Next Generation\") began at\n`Zope Corporation`_ (then Digital Creations).  It seems to have many\nimprovements, but still suffers from many of the problems of classic\nStructuredText.\n\nI decided that a complete rewrite was in order, and even started a\n`reStructuredText SourceForge project`_ (now inactive).  My\nmotivations (the \"itches\" I aim to \"scratch\") are as follows:\n\n- I need a standard format for inline documentation of the programs I\n  write.  This inline documentation has to be convertible to other\n  useful formats, such as HTML.  I believe many others have the same\n  need.\n\n- I believe in the Setext/StructuredText idea and want to help\n  formalize the standard.  However, I feel the current specifications\n  and implementations have flaws that desperately need fixing.\n\n- reStructuredText could form part of the foundation for a\n  documentation extraction and processing system, greatly benefitting\n  Python.  But it is only a part, not the whole.  reStructuredText is\n  a markup language specification and a reference parser\n  implementation, but it does not aspire to be the entire system.  I\n  don't want reStructuredText or a hypothetical Python documentation\n  processor to die stillborn because of over-ambition.\n\n- Most of all, I want to help ease the documentation chore, the bane\n  of many a programmer.\n\nUnfortunately I was sidetracked and stopped working on this project.\nIn November 2000 I made the time to enumerate the problems of\nStructuredText and possible solutions, and complete the first draft of\na specification.  This first draft was posted to the Doc-SIG in three\nparts:\n\n- `A Plan for Structured Text`__\n- `Problems With StructuredText`__\n- `reStructuredText: Revised Structured Text Specification`__\n\n__ https://mail.python.org/pipermail/doc-sig/2000-November/001239.html\n__ https://mail.python.org/pipermail/doc-sig/2000-November/001240.html\n__ https://mail.python.org/pipermail/doc-sig/2000-November/001241.html\n\nIn March 2001 a flurry of activity on the Doc-SIG spurred me to\nfurther revise and refine my specification, the result of which you\nare now reading.  An offshoot of the reStructuredText project has been\nthe realization that a single markup scheme, no matter how well\nthought out, may not be enough.  In order to tame the endless debates\non Doc-SIG, a flexible `Docstring Processing System framework`_ needed\nto be constructed.  This framework has become the more important of\nthe two projects; reStructuredText_ has found its place as one\npossible choice for a single component of the larger framework.\n\nThe project web site and the first project release were rolled out in\nJune 2001, including posting the second draft of the spec [#spec-2]_\nand the first draft of PEPs 256, 257, and 258 [#peps-1]_ to the\nDoc-SIG.  These documents and the project implementation proceeded to\nevolve at a rapid pace.  Implementation history details can be found\nin the `project history file`_.\n\nIn November 2001, the reStructuredText parser was nearing completion.\nDevelopment of the parser continued with the addition of small\nconvenience features, improvements to the syntax, the filling in of\ngaps, and bug fixes.  After a long holiday break, in early 2002 most\ndevelopment moved over to the other Docutils components, the\n\"Readers\", \"Writers\", and \"Transforms\".  A \"standalone\" reader\n(processes standalone text file documents) was completed in February,\nand a basic HTML writer (producing HTML 4.01, using CSS-1) was\ncompleted in early March.\n\n`PEP 287`_, \"reStructuredText Standard Docstring Format\", was created\nto formally propose reStructuredText as a standard format for Python\ndocstrings, PEPs, and other files.  It was first posted to\ncomp.lang.python_ and the Python-dev_ mailing list on 2002-04-02.\n\nVersion 0.4 of the reStructuredText__ and `Docstring Processing\nSystem`_ projects were released in April 2002.  The two projects were\nimmediately merged, renamed to \"Docutils_\", and a 0.1 release soon\nfollowed.\n\n.. __: `reStructuredText SourceForge project`_\n\n..

In particular, notice where the braces fall that delimit the\n   effect of the command: Right: ``{\\displaystyle ...}`` Wrong:\n   ``\\displaystyle{...}``.\n\n   With math_output_ MathML, the declaration must be the first element\n   after the opening bracket.\n\n\nAppendix\n========\n\nTests\n-----\n\n\nFont changes\n~~~~~~~~~~~~\n\nMath alphabet macros change the default alphabet

Note::\n\n   This document is a detailed technical specification; it is not a\n   tutorial or a primer.  If this is your first exposure to\n   reStructuredText, please read `A ReStructuredText Primer`_ and the\n   `Quick reStructuredText`_ user reference first.\n\n.. _A ReStructuredText Primer: ../../user/rst/quickstart.html\n.. _Quick reStructuredText: ../../user/rst/quickref.html\n\n\nreStructuredText_ is plaintext that uses simple and intuitive\nconstructs to indicate the structure of a document.  These constructs\nare equally easy to read in raw and processed forms.  This document is\nitself an example of reStructuredText (raw, if you are reading the\ntext file, or processed, if you are reading an HTML document, for\nexample).  The reStructuredText parser is a component of Docutils_.\n\nSimple, implicit markup is used to indicate special constructs, such\nas section headings, bullet lists, and emphasis.  The markup used is\nas minimal and unobtrusive as possible.  Less often-used constructs\nand extensions to the basic reStructuredText syntax may have more\nelaborate or explicit markup.\n\nreStructuredText is applicable to documents of any length, from the\nvery small (such as inline program documentation fragments, e.g.\nPython docstrings) to the quite large (this document).\n\nThe first section gives a quick overview of the syntax of the\nreStructuredText markup by example.  A complete specification is given\nin the `Syntax Details`_ section.\n\n`Literal blocks`_ (in which no markup processing is done) are used for\nexamples throughout this document, to illustrate the plaintext markup.\n\n\n.. contents::\n\n\n-----------------------\n Quick Syntax Overview\n-----------------------\n\nA reStructuredText document is made up of body or block-level\nelements, and may be structured into sections.  Sections_ are\nindicated through title style (underlines & optional overlines).\nSections contain body elements and/or subsections.  Some body elements\ncontain further elements, such as lists containing list items, which\nin turn may contain paragraphs and other body elements.  Others, such\nas paragraphs, contain text and `inline markup`_ elements.\n\nHere are examples of `body elements`_:\n\n- Paragraphs_ (and `inline markup`_)::\n\n      Paragraphs contain text and may contain inline markup:\n      *emphasis*, **strong emphasis**, `interpreted text`, ``inline\n      literals``, standalone hyperlinks (https://www.python.org),\n      external hyperlinks (Python_), internal cross-references\n      (example_), footnote references ([1]_), citation references\n      ([CIT2002]_), substitution references (|example|), and _`inline\n      internal targets`.\n\n      Paragraphs are separated by blank lines and are left-aligned.\n\n- Five types of lists:\n\n  1. `Bullet lists`_::\n\n         - This is a bullet list.\n\n         - Bullets can be \"*\", \"+\", or \"-\".\n\n  2. `Enumerated lists`_::\n\n         1. This is an enumerated list.\n\n         2. Enumerators may be arabic numbers, letters, or roman\n            numerals.\n\n  3. `Definition lists`_::\n\n         what\n             Definition lists associate a term with a definition.\n\n         how\n             The term is a one-line phrase, and the definition is one\n             or more paragraphs or body elements, indented relative to\n             the term.\n\n  4. `Field lists`_::\n\n         :what: Field lists map field names to field bodies, like\n                database records.  They are often part of an extension\n                syntax.\n\n         :how: The field marker is a colon, the field name, and a\n               colon.\n\n               The field body may contain one or more body elements,\n               indented relative to the field marker.\n\n  5. `Option lists`_, for listing command-line options::\n\n         -a            command-line option \"a\"\n         -b file       options can have arguments\n                       and long descriptions\n         --long        options can be long also\n         --input=file  long options can also have\n                       arguments\n         /V            DOS/VMS-style options too\n\n     There must be at least two spaces between the option and the\n     description.\n\n- `Literal blocks`_::\n\n      Literal blocks are either indented or line-prefix-quoted blocks,\n      and indicated with a double-colon (\"::\") at the end of the\n      preceding paragraph (right here -->)::\n\n          if literal_block:\n              text = 'is left as-is'\n              spaces_and_linebreaks = 'are preserved'\n              markup_processing = None\n\n- `Block quotes`_::\n\n      Block quotes consist of indented body elements:\n\n          This theory, that is mine, is mine.\n\n          -- Anne Elk (Miss)\n\n- `Doctest blocks`_::\n\n      >>> print 'Python-specific usage examples; begun with \">>>\"'\n      Python-specific usage examples; begun with \">>>\"\n      >>> print '(cut and pasted from interactive Python sessions)'\n      (cut and pasted from interactive Python sessions)\n\n- Two syntaxes for tables_:\n\n  1. `Grid tables`_; complete, but complex and verbose::\n\n         +------------------------+------------+----------+\n         | Header row, column 1   | Header 2   | Header 3 |\n         +========================+============+==========+\n         | body row 1, column 1   | column 2   | column 3 |\n         +------------------------+------------+----------+\n         | body row 2             | Cells may span        |\n         +------------------------+-----------------------+\n\n  2. `Simple tables`_; easy and compact, but limited::\n\n         ====================  ==========  ==========\n         Header row, column 1  Header 2    Header 3\n         ====================  ==========  ==========\n         body row 1, column 1  column 2    column 3\n         body row 2            Cells may span columns\n         ====================  ======================\n\n- `Explicit markup blocks`_ all begin with an explicit block marker,\n  two periods and a space:\n\n  - Footnotes_::\n\n        .. [1] A footnote contains body elements, consistently\n           indented by at least 3 spaces.\n\n  - Citations_::\n\n        .. [CIT2002] Just like a footnote, except the label is\n           textual.\n\n  - `Hyperlink targets`_::\n\n        .. _Python: https://www.python.org\n\n        .. _example:\n\n        The \"_example\" target above points to this paragraph.\n\n  - Directives_::\n\n        .. image:: mylogo.png\n\n  - `Substitution definitions`_::\n\n        .. |symbol here| image:: symbol.png\n\n  - Comments_::\n\n        .. Comments begin with two dots and a space.  Anything may\n           follow, except for the syntax of footnotes/citations,\n           hyperlink targets, directives, or substitution definitions.\n\n\n----------------\n Syntax Details\n----------------\n\nDescriptions below list \"doctree elements\" (document tree element\nnames; XML DTD generic identifiers) corresponding to syntax\nconstructs.  For details on the hierarchy of elements, please see `The\nDocutils Document Tree`_ and the `Docutils Generic DTD`_ XML document\ntype definition.\n\n\nWhitespace\n==========\n\nSpaces are recommended for indentation_, but tabs may also be used.\nTabs will be converted to spaces.  Tab stops are at every 8th column\n(processing systems may make this value configurable).\n\nOther whitespace characters (form feeds [chr(12)] and vertical tabs\n[chr(11)]) are converted to single spaces before processing.\n\n\nBlank Lines\n-----------\n\nBlank lines are used to separate paragraphs and other elements.\nMultiple successive blank lines are equivalent to a single blank line,\nexcept within literal blocks (where all whitespace is preserved).\nBlank lines may be omitted when the markup makes element separation\nunambiguous, in conjunction with indentation.  The first line of a\ndocument is treated as if it is preceded by a blank line, and the last\nline of a document is treated as if it is followed by a blank line.\n\n\nIndentation\n-----------\n\nIndentation is used to indicate -- and is only significant in\nindicating -- block quotes, definitions (in `definition lists`_),\nand local nested content:\n\n- list item content (multi-line contents of list items, and multiple\n  body elements within a list item, including nested lists),\n- the content of `literal blocks`_, and\n- the content of `explicit markup blocks`_ (directives, footnotes, ...).\n\nAny text whose indentation is less than that of the current level\n(i.e., unindented text or \"dedents\") ends the current level of\nindentation.\n\nSince all indentation is significant, the level of indentation must be\nconsistent.  For example, indentation is the sole markup indicator for\n`block quotes`_::\n\n    This is a top-level paragraph.\n\n        This paragraph belongs to a first-level block quote.\n\n        Paragraph 2 of the first-level block quote.\n\nMultiple levels of indentation within a block quote will result in\nmore complex structures::\n\n    This is a top-level paragraph.\n\n        This paragraph belongs to a first-level block quote.\n\n            This paragraph belongs to a second-level block quote.\n\n    Another top-level paragraph.\n\n            This paragraph belongs to a second-level block quote.\n\n        This paragraph belongs to a first-level block quote.  The\n        second-level block quote above is inside this first-level\n        block quote.\n\nWhen a paragraph or other construct consists of more than one line of\ntext, the lines must be left-aligned::\n\n    This is a paragraph.  The lines of\n    this paragraph are aligned at the left.\n\n        This paragraph has problems.  The\n    lines are not left-aligned.  In addition\n      to potential misinterpretation, warning\n        and/or error messages will be generated\n      by the parser.\n\nSeveral constructs begin with a marker, and the body of the construct\nmust be indented relative to the marker.  For constructs using simple\nmarkers (`bullet lists`_, `enumerated lists`_), the level of\nindentation of the body is determined by the position of the first\nline of text. For example::\n\n    - This is the first line of a bullet list\n      item's paragraph.  All lines must align\n      relative to the first line.\n\n          This indented paragraph is interpreted\n          as a block quote.\n\n      Another paragraph belonging to the first list item.\n\n     Because it is not sufficiently indented,\n     this paragraph does not belong to the list\n     item (it's a block quote following the list).\n\nThe body of `explicit markup blocks`_, `field lists`_, and `option\nlists`_ ends above the first line with the same or less indentation\nthan the marker.  For example, field lists may have very long markers\n(containing the field names)::\n\n    :Hello: This field has a short field name, so aligning the field\n            body with the first line is feasible.\n\n    :Number-of-African-swallows-required-to-carry-a-coconut: It would\n        be very difficult to align the field body with the left edge\n        of the first line.  It may even be preferable not to begin the\n        body on the same line as the marker.\n\n\n.. _escape:\n\nEscaping Mechanism\n==================\n\nThe character set universally available to plaintext documents, 7-bit\nASCII, is limited.  No matter what characters are used for markup,\nthey will already have multiple meanings in written text.  Therefore\nmarkup characters will sometimes appear in text without being\nintended as markup.  Any serious markup system requires an escaping\nmechanism to override the default meaning of the characters used for\nthe markup.  In reStructuredText we use the *backslash*, commonly used\nas an escaping character in other domains.\n\nA backslash (``\\``) escapes the following character.\n\n* \"Escaping\" backslash characters are represented by NULL characters in\n  the `Document Tree`_ and removed from the output document by the\n  Docutils writers_.\n\n* Escaped non-white characters are prevented from playing a role in any\n  markup interpretation. The escaped character represents the character\n  itself. (A literal backslash can be specified by two backslashes in a\n  row -- the first backslash escapes the second. [#caveat]_)\n\n* Escaped whitespace characters are removed from the output document\n  together with the escaping backslash. This allows for `character-level\n  inline markup`_.\n\n  In `URI context` [#uri-context]_, backslash-escaped whitespace\n  represents a single space.\n\nBackslashes have no special meaning in `literal context` [#literal-context]_.\nHere, a single backslash represents a literal backslash, without having\nto double up. [#caveat]_\n\n.. [#caveat] Please note that the reStructuredText specification and\n   parser do not address the issue of the representation or extraction of\n   text input (how and in what form the text actually *reaches* the\n   parser). Backslashes and other characters may serve a\n   character-escaping purpose in certain contexts and must be dealt with\n   appropriately.  For example, Python uses backslashes in string\n   literals to escape certain characters. The simplest solution when\n   backslashes appear in Python docstrings is to use raw docstrings::\n\n     r\"\"\"This is a raw docstring.  Backslashes (\\) are not touched.\"\"\"\n\n.. [#uri-context] In contexts where Docutils expects a URI (the link\n   block of `external hyperlink targets`_ or the argument of an image_ or\n   figure_ directive), whitespace is ignored by default\n\n.. [#literal-context] In literal context (`literal blocks`_ and `inline\n   literals`_, content of the code_, math_, and raw_ directives, content\n   of the `\"raw\" role`_ and `custom roles`_ based on it),\n   reStructuredText markup characters lose their semantics so there is no\n   reason to escape them.\n\n.. _reference name:\n\nReference Names\n===============\n\n`Reference names` identify elements for cross-referencing.\n\n.. Note:: References to a target position in external, generated documents\n   must use the auto-generated `identifier key`_ which may differ from the\n   `reference name` due to restrictions on identifiers/labels in the\n   output format.\n\nSimple reference names are single words consisting of alphanumerics\nplus isolated (no two adjacent) internal hyphens, underscores,\nperiods, colons and plus signs; no whitespace or other characters are\nallowed.  Footnote labels (Footnotes_ & `Footnote References`_), citation\nlabels (Citations_ & `Citation References`_), `interpreted text`_ roles,\nand some `hyperlink references`_ use the simple reference name syntax.\n\nReference names using punctuation or whose names are phrases (two or\nmore space-separated words) are called \"phrase-references\".\nPhrase-references are expressed by enclosing the phrase in backquotes\nand treating the backquoted text as a reference name::\n\n    Want to learn about `my favorite programming language`_?\n\n    .. _my favorite programming language: https://www.python.org\n\nSimple reference names may also optionally use backquotes.\n\n.. _`normalized reference names`:\n\nReference names are whitespace-neutral and case-insensitive.  When\nresolving reference names internally:\n\n- whitespace is normalized (one or more spaces, horizontal or vertical\n  tabs, newlines, carriage returns, or form feeds, are interpreted as\n  a single space), and\n\n- case is normalized (all alphabetic characters are converted to\n  lowercase).\n\nFor example, the following `hyperlink references`_ are equivalent::\n\n    - `A HYPERLINK`_\n    - `a    hyperlink`_\n    - `A\n      Hyperlink`_\n\nHyperlinks_, footnotes_, and citations_ all share the same namespace\nfor reference names.  The labels of citations (simple reference names)\nand manually-numbered footnotes (numbers) are entered into the same\ndatabase as other hyperlink names.  This means that a footnote_\n(defined as \"``.. [#note]``\") which can be referred to by a footnote\nreference (``[#note]_``), can also be referred to by a plain hyperlink\nreference (``note_``).  Of course, each type of reference (hyperlink,\nfootnote, citation) may be processed and rendered differently.  Some\ncare should be taken to avoid reference name conflicts.\n\n\nDocument Structure\n==================\n\nDocument\n--------\n\nDoctree element: `document <document element_>`_.\n\n\nThe top-level element of a parsed reStructuredText document is the\n\"document\" element.  After initial parsing, the document element is a\nsimple container for a document fragment, consisting of `body\nelements`_, transitions_, and sections_, but lacking a document title\nor other bibliographic elements.  The code that calls the parser may\nchoose to run one or more optional post-parse transforms_,\nrearranging the document fragment into a complete document with a\ntitle and possibly other metadata elements (author, date, etc.; see\n`Bibliographic Fields`_).\n\n.. _document title:\n\nSpecifically, there is no way to indicate a document title and\nsubtitle explicitly in reStructuredText. [#]_ Instead, a lone top-level\nsection title (see Sections_ below) can be treated as the document\ntitle.  Similarly, a lone second-level section title immediately after\nthe \"document title\" can become the document subtitle.  The rest of\nthe sections are then lifted up a level or two.  See the `DocTitle\ntransform`_ for details.\n\n.. [#] The `\"title\" configuration setting`__ and the `\"title\"\n   directive`__ set the document's `title attribute`_ that does not\n   become part of the document body.\n\n   .. _title attribute: ../doctree.html#title-attribute\n   __ ../../user/config.html#title\n   __ directives.html#metadata-document-title\n\n\nSections\n--------\n\nDoctree elements: section_, title_.\n\nSections are identified through their titles, which are marked up with\nadornment: \"underlines\" below the title text, or underlines and\nmatching \"overlines\" above the title.  An underline/overline is a\nsingle repeated punctuation character that begins in column 1 and\nforms a line extending at least as far as the right edge of the title\ntext. [#]_  Specifically, an underline/overline character may be any\nnon-alphanumeric printable 7-bit ASCII character [#]_.  When an\noverline is used, the length and character used must match the\nunderline.  Underline-only adornment styles are distinct from\noverline-and-underline styles that use the same character.  There may\nbe any number of levels of section titles, although some output\nformats may have limits (HTML has 6 levels).\n\n.. [#] The key is the visual length of the title in a mono-spaced font.\n   The adornment may need more or less characters than title, if the\n   title contains wide__ or combining__ characters.\n\n.. [#] The following are all valid section title adornment\n   characters::\n\n       ! \" # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \\ ] ^ _ ` { | } ~\n\n   Some characters are more suitable than others.  The following are\n   recommended::\n\n       = - ` : . ' \" ~ ^ _ * + #\n\n__ https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms#In_Unicode\n__ https://en.wikipedia.org/wiki/Combining_character\n\nRather than imposing a fixed number and order of section title\nadornment styles, the order enforced will be the order as encountered.\nThe first style encountered will be an outermost title (like HTML H1),\nthe second style will be a subtitle, the third will be a subsubtitle,\nand so on.\n\nBelow are examples of section title styles::\n\n    ===============\n     Section Title\n    ===============\n\n    ---------------\n     Section Title\n    ---------------\n\n    Section Title\n    =============\n\n    Section Title\n    -------------\n\n    Section Title\n    `````````````\n\n    Section Title\n    '''''''''''''\n\n    Section Title\n    .............\n\n    Section Title\n    ~~~~~~~~~~~~~\n\n    Section Title\n    *************\n\n    Section Title\n    +++++++++++++\n\n    Section Title\n    ^^^^^^^^^^^^^\n\nWhen a title has both an underline and an overline, the title text may\nbe inset, as in the first two examples above.  This is merely\naesthetic and not significant.  Underline-only title text may *not* be\ninset.\n\nA blank line after a title is optional.  All text blocks up to the\nnext title of the same or higher level are included in a section (or\nsubsection, etc.).\n\nAll section title styles need not be used, nor need any specific\nsection title style be used.  However, a document must be consistent\nin its use of section titles: once a hierarchy of title styles is\nestablished, sections must use that hierarchy.\n\nEach section title automatically generates a hyperlink target pointing\nto the section.  The text of the hyperlink target (the \"reference\nname\") is the same as that of the section title.  See `Implicit\nHyperlink Targets`_ for a complete description.\n\nSections may contain `body elements`_, transitions_, and nested\nsections.\n\n\nTransitions\n-----------\n\nDoctree element: transition_.\n\n    Instead of subheads, extra space or a type ornament between\n    paragraphs may be used to mark text divisions or to signal\n    changes in subject or emphasis.\n\n    (The Chicago Manual of Style, 14th edition, section 1.80)\n\nTransitions are commonly seen in novels and short fiction, as a gap\nspanning one or more lines, with or without a type ornament such as a\nrow of asterisks.  Transitions separate other body elements.  A\ntransition should not begin or end a section or document, nor should\ntwo transitions be immediately adjacent.\n\nThe syntax for a transition marker is a horizontal line of 4 or more\nrepeated punctuation characters.  The syntax is the same as section\ntitle underlines without title text.  Transition markers require blank\nlines before and after::\n\n    Para.\n\n    ----------\n\n    Para.\n\nUnlike section title underlines, no hierarchy of transition markers is\nenforced, nor do differences in transition markers accomplish\nanything.  It is recommended that a single consistent style be used.\n\nThe processing system is free to render transitions in output in any\nway it likes.  For example, horizontal rules (``<hr>``) in HTML output\nwould be an obvious choice.\n\n\nBody Elements\n=============\n\nParagraphs\n----------\n\nDoctree element: paragraph_.\n\nParagraphs consist of blocks of left-aligned text with no markup\nindicating any other body element.  Blank lines separate paragraphs\nfrom each other and from other body elements.  Paragraphs may contain\n`inline markup`_.\n\nSyntax diagram::\n\n    +------------------------------+\n    | paragraph                    |\n    |                              |\n    +------------------------------+\n\n    +------------------------------+\n    | paragraph                    |\n    |                              |\n    +------------------------------+\n\n\nBullet Lists\n------------\n\nDoctree elements: bullet_list_, list_item_.\n\nA text block which begins with a \"*\", \"+\", \"-\", \"•\", \"‣\", or \"⁃\",\nfollowed by whitespace, is a bullet list item (a.k.a. \"unordered\" list\nitem).  List item bodies must be left-aligned and indented relative to\nthe bullet; the text immediately after the bullet determines the\nindentation.  For example::\n\n    - This is the first bullet list item.  The blank line above the\n      first list item is required; blank lines between list items\n      (such as below this paragraph) are optional.\n\n    - This is the first paragraph in the second item in the list.\n\n      This is the second paragraph in the second item in the list.\n      The blank line above this paragraph is required.  The left edge\n      of this paragraph lines up with the paragraph above, both\n      indented relative to the bullet.\n\n      - This is a sublist.  The bullet lines up with the left edge of\n        the text blocks above.  A sublist is a new list so requires a\n        blank line above and below.\n\n    - This is the third item of the main list.\n\n    This paragraph is not part of the list.\n\nHere are examples of **incorrectly** formatted bullet lists::\n\n    - This first line is fine.\n    A blank line is required between list items and paragraphs.\n    (Warning)\n\n    - The following line appears to be a new sublist, but it is not:\n      - This is a paragraph continuation, not a sublist (since there's\n        no blank line).  This line is also incorrectly indented.\n      - Warnings may be issued by the implementation.\n\nSyntax diagram::\n\n    +------+-----------------------+\n    | \"- \" | list item             |\n    +------| (body elements)+      |\n           +-----------------------+\n\n\nEnumerated Lists\n----------------\n\nDoctree elements: enumerated_list_, list_item_.\n\nEnumerated lists (a.k.a. \"ordered\" lists) are similar to bullet lists,\nbut use enumerators instead of bullets.  An enumerator consists of an\nenumeration sequence member and formatting, followed by whitespace.\nThe following enumeration sequences are recognized:\n\n- arabic numerals: 1, 2, 3, ... (no upper limit).\n- uppercase alphabet characters: A, B, C, ..., Z.\n- lower-case alphabet characters: a, b, c, ..., z.\n- uppercase Roman numerals: I, II, III, IV, ..., MMMMCMXCIX (4999).\n- lowercase Roman numerals: i, ii, iii, iv, ..., mmmmcmxcix (4999).\n\nIn addition, the auto-enumerator, \"#\", may be used to automatically\nenumerate a list.  Auto-enumerated lists may begin with explicit\nenumeration, which sets the sequence.  Fully auto-enumerated lists use\narabic numerals and begin with 1.  (Auto-enumerated lists are new in\nDocutils 0.3.8.)\n\nThe following formatting types are recognized:\n\n- suffixed with a period: \"1.\", \"A.\", \"a.\", \"I.\", \"i.\".\n- surrounded by parentheses: \"(1)\", \"(A)\", \"(a)\", \"(I)\", \"(i)\".\n- suffixed with a right-parenthesis: \"1)\", \"A)\", \"a)\", \"I)\", \"i)\".\n\nWhile parsing an enumerated list, a new list will be started whenever:\n\n- An enumerator is encountered which does not have the same format and\n  sequence type as the current list (e.g. \"1.\", \"(a)\" produces two\n  separate lists).\n\n- The enumerators are not in sequence (e.g., \"1.\", \"3.\" produces two\n  separate lists).\n\nIt is recommended that the enumerator of the first list item be\nordinal-1 (\"1\", \"A\", \"a\", \"I\", or \"i\").  Although other start-values\nwill be recognized, they may not be supported by the output format.  A\nlevel-1 [info] system message will be generated for any list beginning\nwith a non-ordinal-1 enumerator.\n\nLists using Roman numerals must begin with \"I\"/\"i\" or a\nmulti-character value, such as \"II\" or \"XV\".  Any other\nsingle-character Roman numeral (\"V\", \"X\", \"L\", \"C\", \"D\", \"M\") will be\ninterpreted as a letter of the alphabet, not as a Roman numeral.\nLikewise, lists using letters of the alphabet may not begin with\n\"I\"/\"i\", since these are recognized as Roman numeral 1.\n\nThe second line of each enumerated list item is checked for validity.\nThis is to prevent ordinary paragraphs from being mistakenly\ninterpreted as list items, when they happen to begin with text\nidentical to enumerators.  For example, this text is parsed as an\nordinary paragraph::\n\n    A. Einstein was a really\n    smart dude.\n\nHowever, ambiguity cannot be avoided if the paragraph consists of only\none line.  This text is parsed as an enumerated list item::\n\n    A. Einstein was a really smart dude.\n\nIf a single-line paragraph begins with text identical to an enumerator\n(\"A.\", \"1.\", \"(b)\", \"I)\", etc.), the first character will have to be\nescaped in order to have the line parsed as an ordinary paragraph::\n\n    \\A. Einstein was a really smart dude.\n\nExamples of nested enumerated lists::\n\n    1. Item 1 initial text.\n\n       a) Item 1a.\n       b) Item 1b.\n\n    2. a) Item 2a.\n       b) Item 2b.\n\nExample syntax diagram::\n\n    +-------+----------------------+\n    | \"1. \" | list item            |\n    +-------| (body elements)+     |\n            +----------------------+\n\n\nDefinition Lists\n----------------\n\nDoctree elements: definition_list_, definition_list_item_, term_,\nclassifier_, definition_.\n\nEach definition list item contains a term, optional classifiers, and a\ndefinition.\n\n* A `term` is a simple one-line word or phrase.  Escape_ a leading hyphen\n  to prevent recognition as an `option list`_ item.\n\n* Optional `classifiers` may follow the term on the same line, each after\n  an inline \" : \" (space, colon, space).  Inline markup is parsed in the\n  term line before the classifier delimiters are recognized.  A delimiter\n  will only be recognized if it appears outside of any inline markup.\n\n* A `definition` is a block indented relative to the term, and may\n  contain multiple paragraphs and other body elements.  There may be no\n  blank line between a term line and a definition block (this\n  distinguishes definition lists from `block quotes`_). Blank lines are\n  required before the first and after the last definition list item, but\n  are optional in-between.\n\nExample::\n\n    term 1\n        Definition 1.\n\n    term 2\n        Definition 2, paragraph 1.\n\n        Definition 2, paragraph 2.\n\n    term 3 : classifier\n        Definition 3.\n\n    term 4 : classifier one : classifier two\n        Definition 4.\n\n    \\-term 5\n        Without escaping, this would be an option list item.\n\nA definition list may be used in various ways, including:\n\n- As a dictionary or glossary.  The term is the word itself, a\n  classifier may be used to indicate the usage of the term (noun,\n  verb, etc.), and the definition follows.\n\n- To describe program variables.  The term is the variable name, a\n  classifier may be used to indicate the type of the variable (string,\n  integer, etc.), and the definition describes the variable's use in\n  the program.  This usage of definition lists supports the classifier\n  syntax of Grouch_, a system for describing and enforcing a Python\n  object schema.\n\nSyntax diagram::\n\n    +----------------------------+\n    | term [ \" : \" classifier ]* |\n    +--+-------------------------+--+\n       | definition                 |\n       | (body elements)+           |\n       +----------------------------+\n\n\nField Lists\n-----------\n\nDoctree elements: field_list_, field_, field_name_, field_body_.\n\nField lists are used as part of an extension syntax, such as options\nfor directives_, or database-like records meant for further\nprocessing.  They may also be used for two-column table-like\nstructures resembling database records (label & data pairs).\nApplications of reStructuredText may recognize field names and\ntransform fields or field bodies in certain contexts.  For examples,\nsee `Bibliographic Fields`_ below, or the \"image_\" and \"meta_\"\ndirectives in `reStructuredText Directives`_.\n\n.. _field names:\n\nField lists are mappings from *field names* to *field bodies*, modeled on\nRFC822_ headers.  A field name may consist of any characters, but\ncolons (\":\") inside of field names must be backslash-escaped\nwhen followed by whitespace.\\ [#]_\nInline markup is parsed in field names, but care must be taken when\nusing `interpreted text`_ with explicit roles in field names: the role\nmust be a suffix to the interpreted text.  Field names are\ncase-insensitive when further processed or transformed.  The field\nname, along with a single colon prefix and suffix, together form the\nfield marker.  The field marker is followed by whitespace and the\nfield body.  The field body may contain multiple body elements,\nindented relative to the field marker.  The first line after the field\nname marker determines the indentation of the field body.  For\nexample::\n\n    :Date: 2001-08-16\n    :Version: 1\n    :Authors: - Me\n              - Myself\n              - I\n    :Indentation: Since the field marker may be quite long, the second\n       and subsequent lines of the field body do not have to line up\n       with the first line, but they must be indented relative to the\n       field name marker, and they must line up with each other.\n    :Parameter i: integer\n\nThe interpretation of individual words in a multi-word field name is\nup to the application.  The application may specify a syntax for the\nfield name.  For example, second and subsequent words may be treated\nas \"arguments\", quoted phrases may be treated as a single argument,\nand direct support for the \"name=value\" syntax may be added.\n\nStandard RFC822_ headers cannot be used for this construct because\nthey are ambiguous.  A word followed by a colon at the beginning of a\nline is common in written text.  However, in well-defined contexts\nsuch as when a field list invariably occurs at the beginning of a\ndocument (PEPs and email messages), standard RFC822 headers could be\nused.\n\nSyntax diagram (simplified)::\n\n    +--------------------+----------------------+\n    | \":\" field name \":\" | field body           |\n    +-------+------------+                      |\n            | (body elements)+                  |\n            +-----------------------------------+\n\n.. [#] Up to Docutils 0.14, field markers were not recognized when\n   containing a colon.\n\nBibliographic Fields\n````````````````````\n\nDoctree elements: docinfo_, address_, author_, authors_, contact_,\ncopyright_, date_, organization_, revision_, status_, topic_,\nversion_.\n\nWhen a field list is the first element in a document\n(after the document title, if there is one) [#]_, it may have its fields\ntransformed to document bibliographic data.  This bibliographic data\ncorresponds to the front matter of a book, such as the title page and\ncopyright page.\n\n..

Any\nunrecognized fields will remain as generic fields in the docinfo\nelement.\n\nThe registered bibliographic field names and their corresponding\ndoctree elements are as follows:\n\n  ============= ================\n  Field name    doctree element\n  ============= ================\n  Abstract      topic_\n  Address       address_\n  Author        author_\n  Authors       authors_\n  Contact       contact_\n  Copyright     copyright_\n  Date          date_\n  Dedication    topic_\n  Organization  organization_\n  Revision      revision_\n  Status        status_\n  Version       version_\n  ============= ================\n\nThe \"Authors\" field may contain either: a single paragraph consisting\nof a list of authors, separated by \";\" or \",\" (\";\" is checked first,\nso \"Doe, Jane; Doe, John\" will work.); multiple paragraphs (one per\nauthor); or a bullet list whose elements each contain a single\nparagraph per author. In some languages\n(e.g. Swedish), there is no singular/plural distinction between\n\"Author\" and \"Authors\", so only an \"Authors\" field is provided, and a\nsingle name is interpreted as an \"Author\".  If a single name contains\na comma, end it with a semicolon to disambiguate: \":Authors: Doe,\nJane;\".\n\nThe \"Address\" field is for a multi-line surface mailing address.\nNewlines and whitespace will be preserved.\n\nThe \"Dedication\" and \"Abstract\" fields may contain arbitrary body\nelements.  Only one of each is allowed.  They become topic elements\nwith \"Dedication\" or \"Abstract\" titles (or language equivalents)\nimmediately following the docinfo element.\n\nThis field-name-to-element mapping can be replaced for other\nlanguages.  See the `DocInfo transform`_ implementation documentation\nfor details.\n\nUnregistered/generic fields may contain one or more paragraphs or\narbitrary body elements.\nThe field name is also used as a `\"classes\" attribute`_ value after being\nconverted into a valid identifier form.\n\n\nRCS Keywords\n````````````\n\n`Bibliographic fields`_ recognized by the parser are normally checked\nfor RCS [#]_ keywords and cleaned up [#]_.  RCS keywords may be\nentered into source files as \"$keyword$\", and once stored under RCS,\nCVS [#]_, or SVN [#]_, they are expanded to \"$keyword: expansion text $\".\nFor example, a \"Status\" field will be transformed to a \"status\" element::\n\n    :Status: $keyword: expansion text $\n\n.. [#] Revision Control System.\n.. [#] RCS keyword processing can be turned off (unimplemented).\n.. [#] Concurrent Versions System.  CVS uses the same keywords as RCS.\n.. [#] Subversion Versions System. Uses the same keywords as RCS.\n\nProcessed, the \"status\" element's text will become simply \"expansion\ntext\".  The dollar sign delimiters and leading RCS keyword name are\nremoved.\n\nThe RCS keyword processing only kicks in when the field list is in\nbibliographic context (first non-comment construct in the document,\nafter a document title if there is one).\n\n.. _option list:\n\nOption Lists\n------------\n\nDoctree elements: option_list_, option_list_item_, option_group_, option_,\noption_string_, option_argument_, description_.\n\nOption lists map a program's command-line options to descriptions\ndocumenting them.  For example::\n\n    -a         Output all.\n    -b         Output both (this description is\n               quite long).\n    -c arg     Output just arg.\n    --long     Output all day long.\n\n    -p         This option has two paragraphs in the description.\n               This is the first.\n\n               This is the second.  Blank lines may be omitted between\n               options (as above) or left in (as here and below).\n\n    --very-long-option  A VMS-style option.  Note the adjustment for\n                        the required two spaces.\n\n    --an-even-longer-option\n               The description can also start on the next line.\n\n    -2, --two  This option has two variants.\n\n    -f FILE, --file=FILE  These two options are synonyms; both have\n                          arguments.\n\n    /V         A VMS/DOS-style option.\n\nThere are several types of options recognized by reStructuredText:\n\n- Short POSIX options consist of one dash and an option letter.\n- Long POSIX options consist of two dashes and an option word; some\n  systems use a single dash.\n- Old GNU-style \"plus\" options consist of one plus and an option\n  letter (\"plus\" options are deprecated now, their use discouraged).\n- DOS/VMS options consist of a slash and an option letter or word.\n\nPlease note that both POSIX-style and DOS/VMS-style options may be\nused by DOS or Windows software.  These and other variations are\nsometimes used mixed together.  The names above have been chosen for\nconvenience only.\n\nThe syntax for short and long POSIX options is based on the syntax\nsupported by Python's getopt.py_ module, which implements an option\nparser similar to the `GNU libc getopt_long()`_ function but with some\nrestrictions.  There are many variant option systems, and\nreStructuredText option lists do not support all of them.\n\nAlthough long POSIX and DOS/VMS option words may be allowed to be\ntruncated by the operating system or the application when used on the\ncommand line, reStructuredText option lists do not show or support\nthis with any special syntax.  The complete option word should be\ngiven, supported by notes about truncation if and when applicable.\n\nOptions may be followed by an argument placeholder, whose role and\nsyntax should be explained in the description text.\nEither a space or an equals sign may be used as a delimiter between long\noptions and option argument placeholders;\nshort options (\"-\" or \"+\" prefix only) use a space or omit the delimiter.\nOption arguments may take one of two forms:\n\n- Begins with a letter (``[a-zA-Z]``) and subsequently consists of\n  letters, numbers, underscores and hyphens (``[a-zA-Z0-9_-]``).\n- Begins with an open-angle-bracket (``<``) and ends with a\n  close-angle-bracket (``>``); any characters except angle brackets\n  are allowed internally.\n\nMultiple option \"synonyms\" may be listed, sharing a single\ndescription.  They must be separated by comma-space.\n\nThere must be at least two spaces between the option(s) and the\ndescription (which can also start on the next line).  The description\nmay contain multiple body elements.\nThe first line after the option marker determines the indentation of the\ndescription.  As with other types of lists, blank lines are required\nbefore the first option list item and after the last, but are optional\nbetween option entries.\n\nSyntax diagram (simplified)::\n\n    +----------------------------+-------------+\n    | option [\" \" argument] \"  \" | description |\n    +-------+--------------------+             |\n            | (body elements)+                 |\n            +----------------------------------+\n\n\nLiteral Blocks\n--------------\n\nDoctree element: literal_block_.\n\nA paragraph consisting of two colons (\"::\") signifies that the\nfollowing text block(s) comprise a literal block.  The literal block\nmust either be indented or quoted (see below).  No markup processing\nis done within a literal block.  It is left as-is, and is typically\nrendered in a monospaced typeface::\n\n    This is a typical paragraph.  An indented literal block follows.\n\n    ::\n\n        for a in [5,4,3,2,1]:   # this is program code, shown as-is\n            print a\n        print \"it's...\"\n        # a literal block continues until the indentation ends\n\n    This text has returned to the indentation of the first paragraph,\n    is outside of the literal block, and is therefore treated as an\n    ordinary paragraph.\n\nThe paragraph containing only \"::\" will be completely removed from the\noutput; no empty paragraph will remain.\n\nAs a convenience, the \"::\" is recognized at the end of any paragraph.\nIf immediately preceded by whitespace, both colons will be removed\nfrom the output (this is the \"partially minimized\" form).  When text\nimmediately precedes the \"::\", *one* colon will be removed from the\noutput, leaving only one colon visible (i.e., \"::\" will be replaced by\n\":\"; this is the \"fully minimized\" form).\n\nIn other words, these are all equivalent (please pay attention to the\ncolons after \"Paragraph\"):\n\n1. Expanded form::\n\n      Paragraph:\n\n      ::\n\n          Literal block\n\n2. Partially minimized form::\n\n      Paragraph: ::\n\n          Literal block\n\n3. Fully minimized form::\n\n      Paragraph::\n\n          Literal block\n\nAll whitespace (including line breaks, but excluding minimum\nindentation for indented literal blocks) is preserved.  Blank lines\nare required before and after a literal block, but these blank lines\nare not included as part of the literal block.\n\n\nIndented Literal Blocks\n```````````````````````\n\nIndented literal blocks are indicated by indentation relative to the\nsurrounding text (leading whitespace on each line).  The minimum\nindentation will be removed from each line of an indented literal\nblock.  The literal block need not be contiguous; blank lines are\nallowed between sections of indented text.  The literal block ends\nwith the end of the indentation.\n\nSyntax diagram::\n\n    +------------------------------+\n    | paragraph                    |\n    | (ends with \"::\")             |\n    +------------------------------+\n       +---------------------------+\n       | indented literal block    |\n       +---------------------------+\n\n\nQuoted Literal Blocks\n`````````````````````\n\nQuoted literal blocks are unindented contiguous blocks of text where\neach line begins with the same non-alphanumeric printable 7-bit ASCII\ncharacter [#]_.  A blank line ends a quoted literal block.  The\nquoting characters are preserved in the processed document.\n\n.. [#]\n   The following are all valid quoting characters::\n\n       ! \" # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \\ ] ^ _ ` { | } ~\n\n   Note that these are the same characters as are valid for title\n   adornment of sections_.\n\nPossible uses include literate programming in Haskell and email\nquoting::\n\n    John Doe wrote::\n\n    >> Great idea!\n    >\n    > Why didn't I think of that?\n\n    You just did!  ;-)\n\nSyntax diagram::\n\n    +------------------------------+\n    | paragraph                    |\n    | (ends with \"::\")             |\n    +------------------------------+\n    +------------------------------+\n    | \">\" per-line-quoted          |\n    | \">\" contiguous literal block |\n    +------------------------------+\n\n\nLine Blocks\n-----------\n\nDoctree elements: line_block_, line_.  (New in Docutils 0.3.5.)\n\nLine blocks are useful for address blocks, verse (poetry, song\nlyrics), and unadorned lists, where the structure of lines is\nsignificant.  Line blocks are groups of lines beginning with vertical\nbar (\"|\") prefixes.  Each vertical bar prefix indicates a new line, so\nline breaks are preserved.  Initial indents are also significant,\nresulting in a nested structure.  Inline markup is supported.\nContinuation lines are wrapped portions of long lines; they begin with\na space in place of the vertical bar.  The left edge of a continuation\nline must be indented, but need not be aligned with the left edge of\nthe text above it.  A line block ends with a blank line.\n\nThis example illustrates continuation lines::\n\n    | Lend us a couple of bob till Thursday.\n    | I'm absolutely skint.\n    | But I'm expecting a postal order and I can pay you back\n      as soon as it comes.\n    | Love, Ewan.\n\nThis example illustrates the nesting of line blocks, indicated by the\ninitial indentation of new lines::\n\n    Take it away, Eric the Orchestra Leader!\n\n        | A one, two, a one two three four\n        |\n        | Half a bee, philosophically,\n        |     must, *ipso facto*, half not be.\n        | But half the bee has got to be,\n        |     *vis a vis* its entity.  D'you see?\n        |\n        | But can a bee be said to be\n        |     or not to be an entire bee,\n        |         when half the bee is not a bee,\n        |             due to some ancient injury?\n        |\n        | Singing...\n\nSyntax diagram::\n\n    +------+-----------------------+\n    | \"| \" | line                  |\n    +------| continuation line     |\n           +-----------------------+\n\n\nBlock Quotes\n------------\n\nDoctree elements: block_quote_, attribution_.\n\nA text block that is indented relative to the preceding text, without\npreceding markup indicating it to be a literal block or other content,\nis a block quote.  All markup processing (for body elements and inline\nmarkup) continues within the block quote::\n\n    This is an ordinary paragraph, introducing a block quote.\n\n        \"It is my business to know things.  That is my trade.\"\n\n        -- Sherlock Holmes\n\nA block quote may end with an attribution: a text block beginning with\n``--``, ``---``, or a true em-dash, flush left within the block quote.  If\nthe attribution consists of multiple lines, the left edges of the\nsecond and subsequent lines must align.\n\nMultiple block quotes may occur consecutively if terminated with\nattributions.\n\n    Unindented paragraph.\n\n        Block quote 1.\n\n        -- Attribution 1\n\n        Block quote 2.\n\n`Empty comments`_ may be used to explicitly terminate preceding\nconstructs that would otherwise consume a block quote::\n\n    * List item.\n\n    ..\n\n        Block quote 3.\n\nEmpty comments may also be used to separate block quotes::\n\n        Block quote 4.\n\n    ..\n\n        Block quote 5.\n\nBlank lines are required before and after a block quote, but these\nblank lines are not included as part of the block quote.\n\nSyntax diagram::\n\n    +------------------------------+\n    | (current level of            |\n    | indentation)                 |\n    +------------------------------+\n       +---------------------------+\n       | block quote               |\n       | (body elements)+          |\n       |                           |\n       | -- attribution text       |\n       |    (optional)             |\n       +---------------------------+\n\n\nDoctest Blocks\n--------------\n\nDoctree element: doctest_block_.\n\nDoctest blocks are interactive Python sessions cut-and-pasted into\ndocstrings.  They are meant to illustrate usage by example, and\nprovide an elegant and powerful testing environment via the `doctest\nmodule`_ in the Python standard library.\n\nDoctest blocks are text blocks which begin with ``\">>> \"``, the Python\ninteractive interpreter main prompt, and end with a blank line.\nDoctest blocks are treated as a special case of literal blocks,\nwithout requiring the literal block syntax.  If both are present, the\nliteral block syntax takes priority over Doctest block syntax::\n\n    This is an ordinary paragraph.\n\n    >>> print 'this is a Doctest block'\n    this is a Doctest block\n\n    The following is a literal block::\n\n        >>> This is not recognized as a doctest block by\n        reStructuredText.  It *will* be recognized by the doctest\n        module, though!\n\nIndentation is not required for doctest blocks.\n\n\nTables\n------\n\nDoctree elements: table_, tgroup_, colspec_, thead_, tbody_, row_, entry_.\n\nReStructuredText provides two syntax variants for delineating table\ncells: `Grid Tables`_ and `Simple Tables`_. Tables are also generated by\nthe `CSV Table`_ and `List Table`_ directives. The `table\ndirective`_ is used to add a table title or specify options.\n\nAs with other body elements, blank lines are required before and after\ntables.  Tables' left edges should align with the left edge of\npreceding text blocks; if indented, the table is considered to be part\nof a block quote.\n\nOnce isolated, each table cell is treated as a miniature document; the\ntop and bottom cell boundaries act as delimiting blank lines.  Each\ncell contains zero or more body elements.  Cell contents may include\nleft and/or right margins, which are removed before processing.\n\n\nGrid Tables\n```````````\n\nGrid tables provide a complete table representation via grid-like\n\"ASCII art\".  Grid tables allow arbitrary cell contents (body\nelements), and both row and column spans.  However, grid tables can be\ncumbersome to produce, especially for simple data sets.  The `Emacs\ntable mode`_ is a tool that allows easy editing of grid tables, in\nEmacs.  See `Simple Tables`_ for a simpler (but limited)\nrepresentation.\n\nGrid tables are described with a visual grid made up of the characters\n\"-\", \"=\", \"|\", and \"+\".  The hyphen (\"-\") is used for horizontal lines\n(row separators).  The equals sign (\"=\") may be used to separate\noptional header rows from the table body (not supported by the `Emacs\ntable mode`_).  The vertical bar (\"|\") is used for vertical lines\n(column separators).  The plus sign (\"+\") is used for intersections of\nhorizontal and vertical lines.  Example::\n\n    +------------------------+------------+----------+----------+\n    | Header row, column 1   | Header 2   | Header 3 | Header 4 |\n    | (header rows optional) |            |          |          |\n    +========================+============+==========+==========+\n    | body row 1, column 1   | column 2   | column 3 | column 4 |\n    +------------------------+------------+----------+----------+\n    | body row 2             | Cells may span columns.          |\n    +------------------------+------------+---------------------+\n    | body row 3             | Cells may  | - Table cells       |\n    +------------------------+ span rows. | - contain           |\n    | body row 4             |            | - body elements.    |\n    +------------------------+------------+---------------------+\n\nSome care must be taken with grid tables to avoid undesired\ninteractions with cell text in rare cases.  For example, the following\ntable contains a cell in row 2 spanning from column 2 to column 4::\n\n    +--------------+----------+-----------+-----------+\n    | row 1, col 1 | column 2 | column 3  | column 4  |\n    +--------------+----------+-----------+-----------+\n    | row 2        |                                  |\n    +--------------+----------+-----------+-----------+\n    | row 3        |          |           |           |\n    +--------------+----------+-----------+-----------+\n\nIf a vertical bar is used in the text of that cell, it could have\nunintended effects if accidentally aligned with column boundaries::\n\n    +--------------+----------+-----------+-----------+\n    | row 1, col 1 | column 2 | column 3  | column 4  |\n    +--------------+----------+-----------+-----------+\n    | row 2        | Use the command ``ls | more``.   |\n    +--------------+----------+-----------+-----------+\n    | row 3        |          |           |           |\n    +--------------+----------+-----------+-----------+\n\nSeveral solutions are possible.  All that is needed is to break the\ncontinuity of the cell outline rectangle.  One possibility is to shift\nthe text by adding an extra space before::\n\n    +--------------+----------+-----------+-----------+\n    | row 1, col 1 | column 2 | column 3  | column 4  |\n    +--------------+----------+-----------+-----------+\n    | row 2        |  Use the command ``ls | more``.  |\n    +--------------+----------+-----------+-----------+\n    | row 3        |          |           |           |\n    +--------------+----------+-----------+-----------+\n\nAnother possibility is to add an extra line to row 2::\n\n    +--------------+----------+-----------+-----------+\n    | row 1, col 1 | column 2 | column 3  | column 4  |\n    +--------------+----------+-----------+-----------+\n    | row 2        | Use the command ``ls | more``.   |\n    |              |                                  |\n    +--------------+----------+-----------+-----------+\n    | row 3        |          |           |           |\n    +--------------+----------+-----------+-----------+\n\n\nSimple Tables\n`````````````\n\nSimple tables provide a compact and easy to type but limited\nrow-oriented table representation for simple data sets.  Cell contents\nare typically single paragraphs, although arbitrary body elements may\nbe represented in most cells.  Simple tables allow multi-line rows (in\nall but the first column) and column spans, but not row spans.  See\n`Grid Tables`_ above for a complete table representation.\n\nSimple tables are described with horizontal borders made up of \"=\" and\n\"-\" characters.  The equals sign (\"=\") is used for top and bottom\ntable borders, and to separate optional header rows from the table\nbody.  The hyphen (\"-\") is used to indicate column spans in a single\nrow by underlining the joined columns, and may optionally be used to\nexplicitly and/or visually separate rows.\n\nA simple table begins with a top border of equals signs with one or\nmore spaces at each column boundary (two or more spaces recommended).\nRegardless of spans, the top border *must* fully describe all table\ncolumns.  There must be at least two columns in the table (to\ndifferentiate it from section headers).  The top border may be\nfollowed by header rows, and the last of the optional header rows is\nunderlined with '=', again with spaces at column boundaries.  There\nmay not be a blank line below the header row separator; it would be\ninterpreted as the bottom border of the table.  The bottom boundary of\nthe table consists of '=' underlines, also with spaces at column\nboundaries.  For example, here is a truth table, a three-column table\nwith one header row and four body rows::\n\n    =====  =====  =======\n      A      B    A and B\n    =====  =====  =======\n    False  False  False\n    True   False  False\n    False  True   False\n    True   True   True\n    =====  =====  =======\n\nUnderlines of '-' may be used to indicate column spans by \"filling in\"\ncolumn margins to join adjacent columns.  Column span underlines must\nbe complete (they must cover all columns) and align with established\ncolumn boundaries.  Text lines containing column span underlines may\nnot contain any other text.  A column span underline applies only to\none row immediately above it.  For example, here is a table with a\ncolumn span in the header::\n\n    =====  =====  ======\n       Inputs     Output\n    ------------  ------\n      A      B    A or B\n    =====  =====  ======\n    False  False  False\n    True   False  True\n    False  True   True\n    True   True   True\n    =====  =====  ======\n\nEach line of text must contain spaces at column boundaries, except\nwhere cells have been joined by column spans.  Each line of text\nstarts a new row, except when there is a blank cell in the first\ncolumn.  In that case, that line of text is parsed as a continuation\nline.  For this reason, cells in the first column of new rows (*not*\ncontinuation lines) *must* contain some text; blank cells would lead\nto a misinterpretation (but see the tip below).  Also, this mechanism\nlimits cells in the first column to only one line of text.  Use `grid\ntables`_ if this limitation is unacceptable.\n\n.. Tip::\n\n   To start a new row in a simple table without text in the first\n   column in the processed output, use one of these:\n\n   * an empty comment (\"..\"), which may be omitted from the processed\n     output (see Comments_ below)\n\n   * a backslash escape (\"``\\``\") followed by a space (see `Escaping\n     Mechanism`_ above)\n\nUnderlines of '-' may also be used to visually separate rows, even if\nthere are no column spans.  This is especially useful in long tables,\nwhere rows are many lines long.\n\nBlank lines are permitted within simple tables.  Their interpretation\ndepends on the context.  Blank lines *between* rows are ignored.\nBlank lines *within* multi-line rows may separate paragraphs or other\nbody elements within cells.\n\nThe rightmost column is unbounded; text may continue past the edge of\nthe table (as indicated by the table borders).  However, it is\nrecommended that borders be made long enough to contain the entire\ntext.\n\nThe following example illustrates continuation lines (row 2 consists\nof two lines of text, and four lines for row 3), a blank line\nseparating paragraphs (row 3, column 2), text extending past the right\nedge of the table, and a new row which will have no text in the first\ncolumn in the processed output (row 4)::\n\n    =====  =====\n    col 1  col 2\n    =====  =====\n    1      Second column of row 1.\n    2      Second column of row 2.\n           Second line of paragraph.\n    3      - Second column of row 3.\n\n           - Second item in bullet\n             list (row 3, column 2).\n    \\      Row 4; column 1 will be empty.\n    =====  =====\n\n\nExplicit Markup Blocks\n----------------------\n\nThe explicit markup syntax is used for footnotes_, citations_,\n`hyperlink targets`_, directives_, `substitution definitions`_,\nand comments_.\n\nAn explicit markup block is a text block:\n\n- whose first line begins with \"..\" followed by whitespace (the\n  \"explicit markup start\"),\n- whose second and subsequent lines (if any) are indented relative to\n  the first, and\n- which ends before an unindented line.\n\nExplicit markup blocks are analogous to field list items. The\nmaximum common indentation is always removed from the second and\nsubsequent lines of the block body.  Therefore, if the first construct\nfits in one line and the indentation of the first and second\nconstructs should differ, the first construct should not begin on the\nsame line as the explicit markup start.\n\nBlank lines are required between explicit markup blocks and other\nelements, but are optional between explicit markup blocks where\nunambiguous.\n\n\nFootnotes\n`````````\n\nSee also: `Footnote References`_.\n\nDoctree elements: footnote_, label_.\n\nConfiguration settings:\n`footnote_references <footnote_references setting_>`_.\n\n.. _footnote_references setting:\n   ../../user/config.html#footnote-references\n\nEach footnote consists of an explicit markup start (\".. \"), a left\nsquare bracket, the footnote label, a right square bracket, and\nwhitespace, followed by indented body elements.  A footnote label can\nbe:\n\n- a whole decimal number consisting of one or more digits,\n\n- a single \"#\" (denoting `auto-numbered footnotes`_),\n\n- a \"#\" followed by a simple reference name (an `autonumber label`_),\n  or\n\n- a single \"*\" (denoting `auto-symbol footnotes`_).\n\nThe footnote content (body elements) must be consistently indented\nand left-aligned.  The first body element within a\nfootnote may often begin on the same line as the footnote label.\nHowever, if the first element fits on one line and the indentation of\nthe remaining elements differ, the first element must begin on the\nline after the footnote label.  Otherwise, the difference in\nindentation will not be detected.\n\nFootnotes may occur anywhere in the document, not only at the end.\nWhere and how they appear in the processed output depends on the\nprocessing system.\n\nHere is a manually numbered footnote::\n\n    .. [1] Body elements go here.\n\nEach footnote automatically generates a hyperlink target pointing to\nitself.  The text of the hyperlink target name is the same as that of\nthe footnote label.  `Auto-numbered footnotes`_ generate a number as\ntheir footnote label and reference name.  See `Implicit Hyperlink\nTargets`_ for a complete description of the mechanism.\n\nSyntax diagram::\n\n    +-------+-------------------------+\n    | \".. \" | \"[\" label \"]\" footnote  |\n    +-------+                         |\n            | (body elements)+        |\n            +-------------------------+\n\n\nAuto-Numbered Footnotes\n.......................\n\nA number sign (\"#\") may be used as the first character of a footnote\nlabel to request automatic numbering of the footnote or footnote\nreference.\n\nThe first footnote to request automatic numbering is assigned the\nlabel \"1\", the second is assigned the label \"2\", and so on (assuming\nthere are no manually numbered footnotes present; see `Mixed Manual\nand Auto-Numbered Footnotes`_ below).  A footnote which has\nautomatically received a label \"1\" generates an implicit hyperlink\ntarget with name \"1\", just as if the label was explicitly specified.\n\n.. _autonumber label: `autonumber labels`_\n\nA footnote may specify a label explicitly while at the same time\nrequesting automatic numbering: ``[#label]``.  These labels are called\n_`autonumber labels`.  Autonumber labels do two things:\n\n- On the footnote itself, they generate a hyperlink target whose name\n  is the autonumber label (doesn't include the \"#\").\n\n- They allow an automatically numbered footnote to be referred to more\n  than once, as a footnote reference or hyperlink reference.  For\n  example::\n\n      If [#note]_ is the first footnote reference, it will show up as\n      \"[1]\".  We can refer to it again as [#note]_ and again see\n      \"[1]\".  We can also refer to it as note_ (an ordinary internal\n      hyperlink reference).\n\n      .. [#note] This is the footnote labeled \"note\".\n\nThe numbering is determined by the order of the footnotes, not by the\norder of the references.  For footnote references without autonumber\nlabels (``[#]_``), the footnotes and footnote references must be in\nthe same relative order but need not alternate in lock-step.  For\nexample::\n\n    [#]_ is a reference to footnote 1, and [#]_ is a reference to\n    footnote 2.\n\n    .. [#] This is footnote 1.\n    .. [#] This is footnote 2.\n    .. [#] This is footnote 3.\n\n    [#]_ is a reference to footnote 3.\n\nSpecial care must be taken if footnotes themselves contain\nauto-numbered footnote references, or if multiple references are made\nin close proximity.  Footnotes and references are noted in the order\nthey are encountered in the document, which is not necessarily the\nsame as the order in which a person would read them.\n\n\nAuto-Symbol Footnotes\n.....................\n\nAn asterisk (\"*\") may be used for footnote labels to request automatic\nsymbol generation for footnotes and footnote references.  The asterisk\nmay be the only character in the label.  For example::\n\n    Here is a symbolic footnote reference: [*]_.\n\n    .. [*] This is the footnote.\n\nA transform will insert symbols as labels into corresponding footnotes\nand footnote references.  The number of references must be equal to\nthe number of footnotes.  One symbol footnote cannot have multiple\nreferences.\n\nThe standard Docutils system uses the following symbols for footnote\nmarks [#]_:\n\n- asterisk/star (\"*\")\n- dagger (HTML character entity \"&dagger;\", Unicode U+02020)\n- double dagger (\"&Dagger;\"/U+02021)\n- section mark (\"&sect;\"/U+000A7)\n- pilcrow or paragraph mark (\"&para;\"/U+000B6)\n- number sign (\"#\")\n- spade suit (\"&spades;\"/U+02660)\n- heart suit (\"&hearts;\"/U+02665)\n- diamond suit (\"&diams;\"/U+02666)\n- club suit (\"&clubs;\"/U+02663)\n\n.. [#] This list was inspired by the list of symbols for \"Note\n   Reference Marks\" in The Chicago Manual of Style, 14th edition,\n   section 12.51.  \"Parallels\" (\"||\") were given in CMoS instead of\n   the pilcrow.  The last four symbols (the card suits) were added\n   arbitrarily.\n\nIf more than ten symbols are required, the same sequence will be\nreused, doubled and then tripled, and so on (\"**\" etc.).\n\n.. Note:: When using auto-symbol footnotes, the choice of output\n   encoding is important.  Many of the symbols used are not encodable\n   in certain common text encodings such as Latin-1 (ISO 8859-1).  The\n   use of UTF-8 for the output encoding is recommended.  An\n   alternative for HTML and XML output is to use the\n   \"xmlcharrefreplace\" `output encoding error handler`__.\n\n__ ../../user/config.html#output-encoding-error-handler\n\n\nMixed Manual and Auto-Numbered Footnotes\n........................................\n\nManual and automatic footnote numbering may both be used within a\nsingle document, although the results may not be expected.  Manual\nnumbering takes priority.  Only unused footnote numbers are assigned\nto auto-numbered footnotes.  The following example should be\nillustrative::\n\n    [2]_ will be \"2\" (manually numbered),\n    [#]_ will be \"3\" (anonymous auto-numbered), and\n    [#label]_ will be \"1\" (labeled auto-numbered).\n\n    .. [2] This footnote is labeled manually, so its number is fixed.\n\n    .. [#label] This autonumber-labeled footnote will be labeled \"1\".\n       It is the first auto-numbered footnote and no other footnote\n       with label \"1\" exists.  The order of the footnotes is used to\n       determine numbering, not the order of the footnote references.\n\n    .. [#] This footnote will be labeled \"3\".  It is the second\n       auto-numbered footnote, but footnote label \"2\" is already used.\n\n\nCitations\n`````````\n\nSee also: `Citation References`_.\n\nDoctree element: citation_\n\nCitations are identical to footnotes except that they use only\nnon-numeric labels such as ``[note]`` or ``[GVR2001]``.  Citation\nlabels are simple `reference names`_ (case-insensitive single words\nconsisting of alphanumerics plus internal hyphens, underscores, and\nperiods; no whitespace).  Citations may be rendered separately and\ndifferently from footnotes.  For example::\n\n    Here is a citation reference: [CIT2002]_.\n\n    .. [CIT2002] This is the citation.  It's just like a footnote,\n       except the label is textual.\n\n\n.. _hyperlinks:\n\nHyperlink Targets\n`````````````````\n\nDoctree element: target_.\n\nThese are also called _`explicit hyperlink targets`, to differentiate\nthem from `implicit hyperlink targets`_ defined below.\n\nHyperlink targets identify a location within or outside of a document,\nwhich may be linked to by `hyperlink references`_.\n\nHyperlink targets may be named or anonymous.  Named hyperlink targets\nconsist of an explicit markup start (\".. \"), an underscore, the\nreference name (no trailing underscore), a colon, whitespace, and a\nlink block::\n\n    .. _hyperlink-name: link-block\n\nReference names are whitespace-neutral and case-insensitive.  See\n`Reference Names`_ for details and examples.\n\nAnonymous hyperlink targets consist of an explicit markup start\n(\".. \"), two underscores, a colon, whitespace, and a link block; there\nis no reference name::\n\n    .. __: anonymous-hyperlink-target-link-block\n\nAn alternate syntax for anonymous hyperlinks consists of two\nunderscores, a space, and a link block::\n\n    __ anonymous-hyperlink-target-link-block\n\nSee `Anonymous Hyperlinks`_ below.\n\nThere are three types of hyperlink targets: internal, external, and\nindirect.\n\n1. _`Internal hyperlink targets` have empty link blocks.  They provide\n   an end point allowing a hyperlink to connect one place to another\n   within a document.  An internal hyperlink target points to the\n   element following the target. [#]_  For example::\n\n       Clicking on this internal hyperlink will take us to the target_\n       below.\n\n       .. _target:\n\n       The hyperlink target above points to this paragraph.\n\n   Internal hyperlink targets may be \"chained\".  Multiple adjacent\n   internal hyperlink targets all point to the same element::\n\n       .. _target1:\n       .. _target2:\n\n       The targets \"target1\" and \"target2\" are synonyms; they both\n       point to this paragraph.\n\n   If the element \"pointed to\" is an external hyperlink target (with a\n   URI in its link block; see #2 below) the URI from the external\n   hyperlink target is propagated to the internal hyperlink targets;\n   they will all \"point to\" the same URI.  There is no need to\n   duplicate a URI.  For example, all three of the following hyperlink\n   targets refer to the same URI::\n\n       .. _Python DOC-SIG mailing list archive:\n       .. _archive:\n       .. _Doc-SIG: https://mail.python.org/pipermail/doc-sig/\n\n   An inline form of internal hyperlink target is available; see\n   `Inline Internal Targets`_.\n\n   .. [#] Works also, if the internal hyperlink target is \"nested\" at the\n      end of an indented text block. This behaviour allows setting targets\n      to individual list items (except the first, as a preceding internal\n      target applies to the list as a whole)::\n\n       * bullet list\n\n         .. _`second item`:\n\n       * second item, with hyperlink target.\n\n\n2. _`External hyperlink targets` have an absolute or relative URI or\n   email address in their link blocks.  For example, take the\n   following input::\n\n       See the Python_ home page for info.\n\n       `Write to me`_ with your questions.\n\n       .. _Python: https://www.python.org\n       .. _Write to me: jdoe@example.com\n\n   After processing into HTML, the hyperlinks might be expressed as::\n\n       See the <a href=\"https://www.python.org\">Python</a> home page\n       for info.\n\n       <a href=\"mailto:jdoe@example.com\">Write to me</a> with your\n       questions.\n\n   An external hyperlink's URI may begin on the same line as the\n   explicit markup start and target name, or it may begin in an\n   indented text block immediately following, with no intervening\n   blank lines.  If there are multiple lines in the link block, they\n   are concatenated.  Any unescaped whitespace is removed (whitespace is\n   permitted to allow for line wrapping).  The following external\n   hyperlink targets are equivalent::\n\n       .. _one-liner: https://docutils.sourceforge.io/rst.html\n\n       .. _starts-on-this-line: https://\n          docutils.sourceforge.net/rst.html\n\n       .. _entirely-below:\n          https://docutils.\n          sourceforge.net/rst.html\n\n   Escaped whitespace is preserved as intentional spaces, e.g.::\n\n       .. _reference: ../local\\ path\\ with\\ spaces.html\n\n   If an external hyperlink target's URI contains an underscore as its\n   last character, it must be escaped to avoid being mistaken for an\n   indirect hyperlink target::\n\n       This link_ refers to a file called ``underscore_``.\n\n       .. _link: underscore\\_\n\n   It is possible (although not generally recommended) to include URIs\n   directly within hyperlink references.  See `Embedded URIs and Aliases`_\n   below.\n\n3. _`Indirect hyperlink targets` have a hyperlink reference in their\n   link blocks.  In the following example, target \"one\" indirectly\n   references whatever target \"two\" references, and target \"two\"\n   references target \"three\", an internal hyperlink target.  In\n   effect, all three reference the same thing::\n\n       .. _one: two_\n       .. _two: three_\n       .. _three:\n\n   Just as with `hyperlink references`_ anywhere else in a document,\n   if a phrase-reference is used in the link block it must be enclosed\n   in backquotes.  As with `external hyperlink targets`_, the link\n   block of an indirect hyperlink target may begin on the same line as\n   the explicit markup start or the next line.  It may also be split\n   over multiple lines, in which case the lines are joined with\n   whitespace before being normalized.\n\n   For example, the following indirect hyperlink targets are\n   equivalent::\n\n       .. _one-liner: `A HYPERLINK`_\n       .. _entirely-below:\n          `a    hyperlink`_\n       .. _split: `A\n          Hyperlink`_\n\n   It is possible to include an alias directly within hyperlink\n   references. See `Embedded URIs and Aliases`_ below.\n\nIf the reference name contains any colons, either:\n\n- the phrase must be enclosed in backquotes::\n\n      .. _`FAQTS: Computers: Programming: Languages: Python`:\n         http://python.faqts.com/\n\n- or the colon(s) must be backslash-escaped in the link target::\n\n      .. _Chapter One\\: \"Tadpole Days\":\n\n      It's not easy being green...\n\nSee `Implicit Hyperlink Targets`_ below for the resolution of\nduplicate reference names.\n\nSyntax diagram::\n\n    +-------+----------------------+\n    | \".. \" | \"_\" name \":\" link    |\n    +-------+ block                |\n            |                      |\n            +----------------------+\n\n\nAnonymous Hyperlinks\n....................\n\nThe `World Wide Web Consortium`_ recommends in its `HTML Techniques\nfor Web Content Accessibility Guidelines`_ that authors should\n\"clearly identify the target of each link.\"  Hyperlink references\nshould be as verbose as possible, but duplicating a verbose hyperlink\nname in the target is onerous and error-prone.  Anonymous hyperlinks\nare designed to allow convenient verbose hyperlink references, and are\nanalogous to `Auto-Numbered Footnotes`_.  They are particularly useful\nin short or one-off documents.  However, this feature is easily abused\nand can result in unreadable plaintext and/or unmaintainable\ndocuments.  Caution is advised.\n\nAnonymous `hyperlink references`_ are specified with two underscores\ninstead of one::\n\n    See `the web site of my favorite programming language`__.\n\nAnonymous targets begin with \".. __:\"; no reference name is required\nor allowed::\n\n    .. __: https://www.python.org\n\nAs a convenient alternative, anonymous targets may begin with \"__\"\nonly::\n\n    __ https://www.python.org\n\nThe reference name of the reference is not used to match the reference\nto its target.  Instead, the order of anonymous hyperlink references\nand targets within the document is significant: the first anonymous\nreference will link to the first anonymous target.  The number of\nanonymous hyperlink references in a document must match the number of\nanonymous targets.  For readability, it is recommended that targets be\nkept close to references.  Take care when editing text containing\nanonymous references; adding, removing, and rearranging references\nrequire attention to the order of corresponding targets.\n\n\nDirectives\n``````````\n\nDoctree elements: depend on the directive.\n\nDirectives are an extension mechanism for reStructuredText, a way of\nadding support for new constructs without adding new primary syntax\n(directives may support additional syntax locally).  All standard\ndirectives (those implemented and registered in the reference\nreStructuredText parser) are described in the `reStructuredText\nDirectives`_ document, and are always available.  Any other directives\nare domain-specific, and may require special action to make them\navailable when processing the document.\n\nFor example, here's how an image_ may be placed::\n\n    .. image:: mylogo.jpeg\n\nA figure_ (a graphic with a caption) may placed like this::\n\n    .. figure:: larch.png\n\n       The larch.\n\nAn admonition_ (note, caution, etc.) contains other body elements::\n\n    .. note:: This is a paragraph\n\n       - Here is a bullet list.\n\nDirectives are indicated by an explicit markup start (\".. \") followed\nby the directive type, two colons, and whitespace (together called the\n\"directive marker\").  Directive types are case-insensitive single\nwords (alphanumerics plus isolated internal hyphens, underscores,\nplus signs, colons, and periods; no whitespace).  Two colons are used\nafter the directive type for these reasons:\n\n- Two colons are distinctive, and unlikely to be used in common text.\n\n- Two colons avoids clashes with common comment text like::\n\n      .. Danger: modify at your own risk!\n\n- If an implementation of reStructuredText does not recognize a\n  directive (i.e., the directive-handler is not installed), a level-3\n  (error) system message is generated, and the entire directive block\n  (including the directive itself) will be included as a literal\n  block.  Thus \"::\" is a natural choice.\n\nThe directive block consists of any text on the first line of the\ndirective after the directive marker, and any subsequent indented\ntext.  The interpretation of the directive block is up to the\ndirective code.  There are three logical parts to the directive block:\n\n1. Directive arguments.\n2. Directive options.\n3. Directive content.\n\nIndividual directives can employ any combination of these parts.\nDirective arguments can be filesystem paths, URLs, title text, etc.\nDirective options are indicated using `field lists`_; the field names\nand contents are directive-specific.  Arguments and options must form\na contiguous block beginning on the first or second line of the\ndirective; a blank line indicates the beginning of the directive\ncontent block.  If either arguments and/or options are employed by the\ndirective, a blank line must separate them from the directive content.\nThe \"figure\" directive employs all three parts::\n\n    .. figure:: larch.png\n       :scale: 50\n\n       The larch.\n\nSimple directives may not require any content.  If a directive that\ndoes not employ a content block is followed by indented text anyway,\nit is an error.  If a block quote should immediately follow a\ndirective, use an empty comment in-between (see Comments_ below).\n\nActions taken in response to directives and the interpretation of text\nin the directive content block or subsequent text block(s) are\ndirective-dependent.  See `reStructuredText Directives`_ for details.\n\nDirectives are meant for the arbitrary processing of their contents,\nwhich can be transformed into something possibly unrelated to the\noriginal text.  It may also be possible for directives to be used as\npragmas, to modify the behavior of the parser, such as to experiment\nwith alternate syntax.  There is no parser support for this\nfunctionality at present; if a reasonable need for pragma directives\nis found, they may be supported.\n\nDirectives do not generate \"directive\" elements; they are a *parser\nconstruct* only, and have no intrinsic meaning outside of\nreStructuredText.  Instead, the parser will transform recognized\ndirectives into (possibly specialized) document elements.  Unknown\ndirectives will trigger level-3 (error) system messages.\n\nSyntax diagram::\n\n    +-------+-------------------------------+\n    | \".. \" | directive type \"::\" directive |\n    +-------+ block                         |\n            |                               |\n            +-------------------------------+\n\n\nSubstitution Definitions\n````````````````````````\n\nDoctree element: substitution_definition_.\n\nSubstitution definitions are indicated by an explicit markup start\n(\".. \") followed by a vertical bar, the substitution text, another\nvertical bar, whitespace, and the definition block.  Substitution text\nmay not begin or end with whitespace.  A substitution definition block\ncontains an embedded inline-compatible directive (without the leading\n\".. \"), such as \"image_\" or \"replace_\".  For example::\n\n    The |biohazard| symbol must be used on containers used to\n    dispose of medical waste.\n\n    .. |biohazard| image:: biohazard.png\n\nIt is an error for a substitution definition block to directly or\nindirectly contain a circular substitution reference.\n\n`Substitution references`_ are replaced in-line by the processed\ncontents of the corresponding definition (linked by matching\nsubstitution text).  Matches are case-sensitive but forgiving; if no\nexact match is found, a case-insensitive comparison is attempted.\n\nSubstitution definitions allow the power and flexibility of\nblock-level directives_ to be shared by inline text.  They are a way\nto include arbitrarily complex inline structures within text, while\nkeeping the details out of the flow of text.  They are the equivalent\nof SGML/XML's named entities or programming language macros.\n\nWithout the substitution mechanism, every time someone wants an\napplication-specific new inline structure, they would have to petition\nfor a syntax change.  In combination with existing directive syntax,\nany inline structure can be coded without new syntax (except possibly\na new directive).\n\nSyntax diagram::\n\n    +-------+-----------------------------------------------------+\n    | \".. \" | \"|\" substitution text \"| \" directive type \"::\" data |\n    +-------+ directive block                                     |\n            |                                                     |\n            +-----------------------------------------------------+\n\nFollowing are some use cases for the substitution mechanism.  Please\nnote that most of the embedded directives shown are examples only and\nhave not been implemented.\n\nObjects\n    Substitution references may be used to associate ambiguous text\n    with a unique object identifier.\n\n    For example, many sites may wish to implement an inline \"user\"\n    directive::\n\n        |Michael| and |Jon| are our widget-wranglers.\n\n        .. |Michael| user:: mjones\n        .. |Jon|     user:: jhl\n\n    Depending on the needs of the site, this may be used to index the\n    document for later searching, to hyperlink the inline text in\n    various ways (mailto, homepage, mouseover Javascript with profile\n    and contact information, etc.), or to customize presentation of\n    the text (include username in the inline text, include an icon\n    image with a link next to the text, make the text bold or a\n    different color, etc.).\n\n    The same approach can be used in documents which frequently refer\n    to a particular type of objects with unique identifiers but\n    ambiguous common names.  Movies, albums, books, photos, court\n    cases, and laws are possible.  For example::\n\n        |The Transparent Society| offers a fascinating alternate view\n        on privacy issues.\n\n        .. |The Transparent Society| book:: isbn=0738201448\n\n    Classes or functions, in contexts where the module or class names\n    are unclear and/or interpreted text cannot be used, are another\n    possibility::\n\n        4XSLT has the convenience method |runString|, so you don't\n        have to mess with DOM objects if all you want is the\n        transformed output.\n\n        .. |runString| function:: module=xml.xslt class=Processor\n\nImages\n    Images are a common use for substitution references::\n\n        West led the |H| 3, covered by dummy's |H| Q, East's |H| K,\n        and trumped in hand with the |S| 2.\n\n        .. |H| image:: /images/heart.png\n           :height: 11\n           :width: 11\n        .. |S| image:: /images/spade.png\n           :height: 11\n           :width: 11\n\n        * |Red light| means stop.\n        * |Green light| means go.\n        * |Yellow light| means go really fast.\n\n        .. |Red light|    image:: red_light.png\n        .. |Green light|  image:: green_light.png\n        .. |Yellow light| image:: yellow_light.png\n\n        |-><-| is the official symbol of POEE_.\n\n        .. |-><-| image:: discord.png\n        .. _POEE: http://www.poee.org/\n\n    The \"image_\" directive has been implemented.\n\nStyles [#]_\n    Substitution references may be used to associate inline text with\n    an externally defined presentation style::\n\n        Even |the text in Texas| is big.\n\n        .. |the text in Texas| style:: big\n\n    The style name may be meaningful in the context of some particular\n    output format (CSS class name for HTML output, LaTeX style name\n    for LaTeX, etc), or may be ignored for other output formats (such\n    as plaintext).\n\n    .. @@@ This needs to be rethought & rewritten or removed:\n\n       Interpreted text is unsuitable for this purpose because the set\n       of style names cannot be predefined - it is the domain of the\n       content author, not the author of the parser and output\n       formatter - and there is no way to associate a style name\n       argument with an interpreted text style role.  Also, it may be\n       desirable to use the same mechanism for styling blocks::\n\n           .. style:: motto\n              At Bob's Underwear Shop, we'll do anything to get in\n              your pants.\n\n           .. style:: disclaimer\n              All rights reversed.  Reprint what you like.\n\n    .. [#] There may be sufficient need for a \"style\" mechanism to\n       warrant simpler syntax such as an extension to the interpreted\n       text role syntax.  The substitution mechanism is cumbersome for\n       simple text styling.\n\nTemplates\n    Inline markup may be used for later processing by a template\n    engine.  For example, a Zope_ author might write::\n\n        Welcome back, |name|!\n\n        .. |name| tal:: replace user/getUserName\n\n    After processing, this ZPT output would result::\n\n        Welcome back,\n        <span tal:replace=\"user/getUserName\">name</span>!\n\n    Zope would then transform this to something like \"Welcome back,\n    David!\" during a session with an actual user.\n\nReplacement text\n    The substitution mechanism may be used for simple macro\n    substitution.  This may be appropriate when the replacement text\n    is repeated many times throughout one or more documents,\n    especially if it may need to change later.  A short example is\n    unavoidably contrived::\n\n        |RST|_ is a little annoying to type over and over, especially\n        when writing about |RST| itself, and spelling out the\n        bicapitalized word |RST| every time isn't really necessary for\n        |RST| source readability.\n\n        .. |RST| replace:: reStructuredText\n        .. _RST: https://docutils.sourceforge.io/rst.html\n\n    Note the trailing underscore in the first use of a substitution\n    reference.  This indicates a reference to the corresponding\n    hyperlink target.\n\n    Substitution is also appropriate when the replacement text cannot\n    be represented using other inline constructs, or is obtrusively\n    long::\n\n        But still, that's nothing compared to a name like\n        |j2ee-cas|__.\n\n        .. |j2ee-cas| replace::\n           the Java `TM`:super: 2 Platform, Enterprise Edition Client\n           Access Services\n        __ http://developer.java.sun.com/developer/earlyAccess/\n           j2eecas/\n\n    The \"replace_\" directive has been implemented.\n\n\nComments\n````````\n\nDoctree element: comment_.\n\n`Explicit markup blocks`_ that are not recognized as citations_,\ndirectives_, footnotes_, `hyperlink targets`_, or `substitution\ndefinitions`_ will be processed as a comment element. Arbitrary\nindented text may be used on the lines following the explicit markup\nstart. To ensure that none of the other explicit markup constructs is\nrecognized, leave the \"..\" on a line by itself::\n\n    .. This is a comment\n    ..\n       _so: is this!\n    ..\n       [and] this!\n    ..\n       this:: too!\n    ..\n       |even| this:: !\n\n    .. [this] however, is a citation.\n\nApart from removing the maximum common indentation, no further\nprocessing is done on the content; a comment contains a single \"text\nblob\".  Depending on the output formatter, comments may be removed\nfrom the processed output.\n\nSyntax diagram::\n\n    +-------+----------------------+\n    | \".. \" | comment              |\n    +-------+ block                |\n            |                      |\n            +----------------------+\n\nEmpty Comments\n..............\n\nAn explicit markup start followed by a blank line and nothing else\n(apart from whitespace) is an \"_`empty comment`\".  It serves to\nterminate a preceding construct, and does **not** consume any indented\ntext following.  To have a block quote follow a list or any indented\nconstruct, insert an unindented empty comment in-between::\n\n    This is\n      a definition list.\n\n    ..\n\n      This is a block quote.\n\nImplicit Hyperlink Targets\n==========================\n\nImplicit hyperlink targets are generated by section titles, footnotes,\nand citations, and may also be generated by extension constructs.\nImplicit hyperlink targets otherwise behave identically to explicit\n`hyperlink targets`_.\n\nProblems of ambiguity due to conflicting duplicate implicit and\nexplicit reference names are avoided by following this procedure:\n\n1. `Explicit hyperlink targets`_ override any implicit targets having\n   the same reference name.  The implicit hyperlink targets are\n   removed, and level-1 (info) system messages are inserted.\n\n2. Duplicate implicit hyperlink targets are removed, and level-1\n   (info) system messages inserted.  For example, if two or more\n   sections have the same title (such as \"Introduction\" subsections of\n   a rigidly-structured document), there will be duplicate implicit\n   hyperlink targets.\n\n3. Duplicate explicit hyperlink targets are removed, and level-2\n   (warning) system messages are inserted.  Exception: duplicate\n   `external hyperlink targets`_ (identical hyperlink names and\n   referenced URIs) do not conflict, and are not removed.\n\nSystem messages are inserted where target links have been removed.\nSee \"Error Handling\" in `PEP 258`_.\n\nThe parser must return a set of *unique* hyperlink targets.  The\ncalling software (such as the Docutils_) can warn of unresolvable\nlinks, giving reasons for the messages.\n\n\nInline Markup\n=============\n\nIn reStructuredText, inline markup applies to words or phrases within\na text block.  The same whitespace and punctuation that serves to\ndelimit words in written text is used to delimit the inline markup\nsyntax constructs (see the `inline markup recognition rules`_ for\ndetails).  The text within inline markup may not begin or end with\nwhitespace.  Arbitrary `character-level inline markup`_ is supported\nalthough not encouraged.  Inline markup cannot be nested.\n\nThere are nine inline markup constructs.  Five of the constructs use\nidentical start-strings and end-strings to indicate the markup:\n\n- emphasis_: \"*\"\n- `strong emphasis`_: \"**\"\n- `interpreted text`_: \"`\"\n- `inline literals`_: \"``\"\n- `substitution references`_: \"|\"\n\nThree constructs use different start-strings and end-strings:\n\n- `inline internal targets`_: \"_`\" and \"`\"\n- `footnote references`_: \"[\" and \"]_\"\n- `hyperlink references`_: \"`\" and \"\\`_\" (phrases), or just a\n  trailing \"_\" (single words)\n\n`Standalone hyperlinks`_ are recognized implicitly, and use no extra\nmarkup.\n\nInline comments are not supported.\n\n\nInline markup recognition rules\n-------------------------------\n\nInline markup start-strings and end-strings are only recognized if\nthe following conditions are met:\n\n1. Inline markup start-strings must be immediately followed by\n   non-whitespace.\n\n2. Inline markup end-strings must be immediately preceded by\n   non-whitespace.\n\n3. The inline markup end-string must be separated by at least one\n   character from the start-string.\n\n4. Both, inline markup start-string and end-string must not be preceded by\n   an unescaped backslash (except for the end-string of `inline literals`_).\n   See `Escaping Mechanism`_ above for details.\n\n5. If an inline markup start-string is immediately preceded by one of the\n   ASCII characters ``' \" < ( [ {`` or a similar\n   non-ASCII character [#openers]_, it must not be followed by the\n   corresponding closing character from ``' \" > ) ] }`` or a similar\n   non-ASCII character [#closers]_. (For quotes, matching characters can\n   be any of the `quotation marks in international usage`_.)\n\nIf the configuration setting `character-level-inline-markup`_ is False\n(default), additional conditions apply to the characters \"around\" the\ninline markup:\n\n6. Inline markup start-strings must start a text block or be\n   immediately preceded by\n\n   * whitespace,\n   * one of the ASCII characters ``- : / ' \" < ( [ {``\n   * or a similar non-ASCII punctuation character. [#pre-chars]_\n\n7. Inline markup end-strings must end a text block or be immediately\n   followed by\n\n   * whitespace,\n   * one of the ASCII characters ``- . , : ; ! ? \\ / ' \" ) ] } >``\n   * or a similar non-ASCII punctuation character. [#post-chars]_\n\n.. [#openers]    `Unicode categories`_ `Ps` (Open), `Pi` (Initial quote),\n                 or `Pf` (Final quote). [#uni-version]_\n.. [#closers]    Unicode categories `Pe` (Close), `Pi` (Initial quote),\n                 or `Pf` (Final quote). [#uni-version]_\n.. [#pre-chars]  Unicode categories `Ps` (Open), `Pi` (Initial quote),\n                 `Pf` (Final quote), `Pd` (Dash), or `Po` (Other). [#uni-version]_\n.. [#post-chars] Unicode categories  `Pe` (Close), `Pi` (Initial quote),\n                 `Pf` (Final quote), `Pd` (Dash), or `Po` (Other). [#uni-version]_\n\n.. [#uni-version] The category of some characters changed with the\n   development of the Unicode standard.\n   Docutils 0.13 uses `Unicode version 5.2.0`_.\n\n.. _Unicode categories:\n   https://www.unicode.org/Public/5.1.0/ucd/UCD.html#General_Category_Values\n.. _Unicode version 5.2.0: https://www.unicode.org/Public/5.2.0/\n.. _quotation marks in international usage:\n   https://en.wikipedia.org/wiki/Quotation_mark,_non-English_usage\n\nThe inline markup recognition rules were devised to allow 90% of non-markup\nuses of \"*\", \"`\", \"_\", and \"|\" without escaping. For example, none of the\nfollowing terms are recognized as containing inline markup strings:\n\n- 2 * x  a ** b  (* BOM32_* ` `` _ __ | (breaks rule 1)\n- || (breaks rule 3)\n- \"*\" '|' (*) [*] {*} <*>\n  ‘*’ ‚*‘ ‘*‚ ’*’ ‚*’\n  “*” „*“ “*„ ”*” „*”\n  »*« ›*‹ «*» »*» ›*› (breaks rule 5)\n- 2*x a**b O(N**2) e**(x*y) f(x)*f(y) a|b file*.*\n  __init__ __init__()  (breaks rule 6)\n\nNo escaping is required inside the following inline markup examples:\n\n- ``*2 * x  *a **b *.txt*`` (breaks rule 2; renders as \"*2 * x  *a **b *.txt*\")\n- ``*2*x a**b O(N**2) e**(x*y) f(x)*f(y) a*(1+2)*``\n  (breaks rule 7; renders as \"*2*x a**b O(N**2) e**(x*y) f(x)*f(y) a*(1+2)*\")\n\nIt may be desirable to use `inline literals`_ for some of these anyhow,\nespecially if they represent code snippets.  It's a judgment call.\n\nThe following terms *do* require either literal-quoting or escaping to avoid\nmisinterpretation::\n\n    *4, class_, *args, **kwargs, `TeX-quoted', *ML, *.txt\n\nIn most use cases, `inline literals`_ or `literal blocks`_ are the best\nchoice (by default, this also selects a monospaced font). Alternatively, the\ninline markup characters can be escaped::\n\n    \\*4, class\\_, \\*args, \\**kwargs, \\`TeX-quoted', \\*ML, \\*.txt\n\n\nFor languages that don't use whitespace between words (e.g. Japanese or\nChinese) it is recommended to set `character-level-inline-markup`_ to\nTrue and eventually escape inline markup characters.\nThe examples breaking rules 6 and 7 above show which constructs may need\nspecial attention.\n\n.. _character-level-inline-markup:\n   ../../user/config.html#character-level-inline-markup\n\n\nRecognition order\n-----------------\n\nInline markup delimiter characters are used for multiple constructs,\nso to avoid ambiguity there must be a specific recognition order for\neach character.  The inline markup recognition order is as follows:\n\n- Asterisks: `Strong emphasis`_ (\"**\") is recognized before emphasis_\n  (\"*\").\n\n- Backquotes: `Inline literals`_ (\"``\"), `inline internal targets`_\n  (leading \"_`\", trailing \"`\"), are mutually independent, and are\n  recognized before phrase `hyperlink references`_ (leading \"`\",\n  trailing \"\\`_\") and `interpreted text`_ (\"`\").\n\n- Trailing underscores: Footnote references (\"[\" + label + \"]_\") and\n  simple `hyperlink references`_ (name + trailing \"_\") are mutually\n  independent.\n\n- Vertical bars: `Substitution references`_ (\"|\") are independently\n  recognized.\n\n- `Standalone hyperlinks`_ are the last to be recognized.\n\n\nCharacter-Level Inline Markup\n-----------------------------\n\nIt is possible to mark up individual characters within a word with\nbackslash escapes (see `Escaping Mechanism`_ above).  Backslash\nescapes can be used to allow arbitrary text to immediately follow\ninline markup::\n\n    Python ``list``\\s use square bracket syntax.\n\nThe backslash will disappear from the processed document.  The word\n\"list\" will appear as inline literal text, and the letter \"s\" will\nimmediately follow it as normal text, with no space in-between.\n\nArbitrary text may immediately precede inline markup using\nbackslash-escaped whitespace::\n\n    Possible in *re*\\ ``Structured``\\ *Text*, though not encouraged.\n\nThe backslashes and spaces separating \"re\", \"Structured\", and \"Text\"\nabove will disappear from the processed document.\n\n.. CAUTION::\n\n   The use of backslash-escapes for character-level inline markup is\n   not encouraged.  Such use is ugly and detrimental to the\n   unprocessed document's readability.  Please use this feature\n   sparingly and only where absolutely necessary.\n\n\nEmphasis\n--------\n\nDoctree element: emphasis_.\n\nStart-string = end-string = \"*\".\n\nText enclosed by single asterisk characters is emphasized::\n\n    This is *emphasized text*.\n\nEmphasized text is typically displayed in italics.\n\n\nStrong Emphasis\n---------------\n\nDoctree element: strong_.\n\nStart-string = end-string = \"**\".\n\nText enclosed by double-asterisks is emphasized strongly::\n\n    This is **strong text**.\n\nStrongly emphasized text is typically displayed in boldface.\n\n\nInterpreted Text\n----------------\n\nDoctree element: depends on the explicit or implicit role and\nprocessing.\n\nStart-string = end-string = \"`\".\n\nInterpreted text is text that is meant to be related, indexed, linked,\nsummarized, or otherwise processed, but the text itself is typically\nleft alone.  Interpreted text is enclosed by single backquote\ncharacters::\n\n    This is `interpreted text`.\n\nThe \"role\" of the interpreted text determines how the text is\ninterpreted.  The role may be inferred implicitly (as above; the\n\"default role\" is used) or indicated explicitly, using a role marker.\nA role marker consists of a colon, the role name, and another colon.\nA role name is a single word consisting of alphanumerics plus isolated\ninternal hyphens, underscores, plus signs, colons, and periods;\nno whitespace or other characters are allowed.  A role marker is\neither a prefix or a suffix to the interpreted text, whichever reads\nbetter; it's up to the author::\n\n    :role:`interpreted text`\n\n    `interpreted text`:role:\n\nInterpreted text allows extensions to the available inline descriptive\nmarkup constructs.  To emphasis_, `strong emphasis`_, `inline\nliterals`_, and `hyperlink references`_, we can add \"title reference\",\n\"index entry\", \"acronym\", \"class\", \"red\", \"blinking\" or anything else\nwe want (as long as it is a simple `reference name`_).\nOnly pre-determined roles are recognized; unknown roles will\ngenerate errors.  A core set of standard roles is implemented in the\nreference parser; see `reStructuredText Interpreted Text Roles`_ for\nindividual descriptions.  The role_ directive can be used to define\ncustom interpreted text roles.  In addition, applications may support\nspecialized roles.\n\nIn `field lists`_, care must be taken when using interpreted text with\nexplicit roles in field names: the role must be a suffix to the\ninterpreted text. The following are recognized as field list items::\n\n    :`field name`:code:: interpreted text with explicit role as suffix\n\n    :a `complex`:code:\\  field name: a backslash-escaped space\n                                     is necessary\n\nThe following are **not** recognized as field list items::\n\n    ::code:`not a field name`: paragraph with interpreted text\n\n    :code:`not a field name`: paragraph with interpreted text\n\nEdge cases::\n\n    :field\\:`name`: interpreted text (standard role) requires\n                    escaping the leading colon in a field name\n\n    :field:\\`name`: not interpreted text\n\n\nInline Literals\n---------------\n\nDoctree element: literal_.\n\nStart-string = end-string = \"``\".\n\nText enclosed by double-backquotes is treated as inline literals::\n\n    This text is an example of ``inline literals``.\n\nInline literals may contain any characters except two adjacent\nbackquotes in an end-string context (according to the recognition\nrules above).  No markup interpretation (including backslash-escape\ninterpretation) is done within inline literals.\n\nLine breaks and sequences of whitespace characters\nare *not* protected in inline literals.\nAlthough a reStructuredText parser will preserve them in its output,\nthe final representation of the processed document depends on the\noutput formatter, thus the preservation of whitespace cannot be\nguaranteed.  If the preservation of line breaks and/or other\nwhitespace is important, `literal blocks`_ should be used.\n\nInline literals are useful for short code snippets.  For example::\n\n    The regular expression ``[+-]?(\\d+(\\.\\d*)?|\\.\\d+)`` matches\n    floating-point numbers (without exponents).\n\n\nHyperlink References\n--------------------\n\nDoctree element: reference_.\n\n- Named hyperlink references:\n\n  - No start-string, end-string = \"_\".\n  - Start-string = \"`\", end-string = \"\\`_\".  (Phrase references.)\n\n- Anonymous hyperlink references:\n\n  - No start-string, end-string = \"__\".\n  - Start-string = \"`\", end-string = \"\\`__\".  (Phrase references.)\n\nHyperlink references are indicated by a trailing underscore, \"_\",\nexcept for `standalone hyperlinks`_ which are recognized\nindependently.  The underscore can be thought of as a right-pointing\narrow.  The trailing underscores point away from hyperlink references,\nand the leading underscores point toward `hyperlink targets`_.\n\nHyperlinks consist of two parts.  In the text body, there is a source\nlink, a reference name with a trailing underscore (or two underscores\nfor `anonymous hyperlinks`_)::\n\n    See the Python_ home page for info.\n\nA target link with a matching reference name must exist somewhere else\nin the document.  See `Hyperlink Targets`_ for a full description).\n\n`Anonymous hyperlinks`_ (which see) do not use reference names to\nmatch references to targets, but otherwise behave similarly to named\nhyperlinks.\n\n\nEmbedded URIs and Aliases\n`````````````````````````\n\nA hyperlink reference may directly embed a target URI or (since\nDocutils 0.11) a hyperlink reference within angle brackets (\"<...>\")\nas follows::\n\n    See the `Python home page <https://www.python.org>`_ for info.\n\n    This `link <Python home page_>`_ is an alias to the link above.\n\nThis is exactly equivalent to::\n\n    See the `Python home page`_ for info.\n\n    This link_ is an alias to the link above.\n\n    .. _Python home page: https://www.python.org\n    .. _link: `Python home page`_\n\nThe bracketed URI must be preceded by whitespace and be the last text\nbefore the end string.\n\nWith a single trailing underscore, the reference is named and the same\ntarget URI may be referred to again.\nWith two trailing underscores, the reference and target are both\nanonymous, and the target cannot be referred to again.  These are\n\"one-off\" hyperlinks.  For example::\n\n    `RFC 2396 <https://www.rfc-editor.org/rfc/rfc2396.txt>`__ and `RFC\n    2732 <https://www.rfc-editor.org/rfc/rfc2732.txt>`__ together\n    define the syntax of URIs.\n\nEquivalent to::\n\n    `RFC 2396`__ and `RFC 2732`__ together define the syntax of URIs.\n\n    __ https://www.rfc-editor.org/rfc/rfc2396.txt\n    __ https://www.rfc-editor.org/rfc/rfc2732.txt\n\n`Standalone hyperlinks`_ are treated as URIs, even if they end with an\nunderscore like in the example of a Python function documentation::\n\n    `__init__ <http:example.py.html#__init__>`__\n\nIf a target URI that is not recognized as `standalone hyperlink`_ happens\nto end with an underscore, this needs to be backslash-escaped to avoid\nbeing parsed as hyperlink reference. For example ::\n\n    Use the `source <parrots.txt\\_>`__.\n\ncreates an anonymous reference to the file ``parrots.txt_``.\n\nIf the reference text happens to end with angle-bracketed text that is\n*not* a URI or hyperlink reference, at least one angle-bracket needs to\nbe backslash-escaped or an escaped space should follow. For example, here\nare three references to titles describing a tag::\n\n    See `HTML Element: \\<a>`_, `HTML Element: <b\\> `_, and\n    `HTML Element: <c>\\ `_.\n\nThe reference text may also be omitted, in which case the URI will be\nduplicated for use as the reference text.  This is useful for relative\nURIs where the address or file name is also the desired reference\ntext::\n\n    See `<a_named_relative_link>`_ or `<an_anonymous_relative_link>`__\n    for details.\n\n.. CAUTION::\n\n   This construct offers easy authoring and maintenance of hyperlinks\n   at the expense of general readability.  Inline URIs, especially\n   long ones, inevitably interrupt the natural flow of text.  For\n   documents meant to be read in source form, the use of independent\n   block-level `hyperlink targets`_ is **strongly recommended**.  The\n   embedded URI construct is most suited to documents intended *only*\n   to be read in processed form.\n\n\nInline Internal Targets\n------------------------\n\nDoctree element: target_.\n\nStart-string = \"_`\", end-string = \"`\".\n\nInline internal targets are the equivalent of explicit `internal\nhyperlink targets`_, but may appear within running text.  The syntax\nbegins with an underscore and a backquote, is followed by a hyperlink\nname or phrase, and ends with a backquote.  Inline internal targets\nmay not be anonymous.\n\nFor example, the following paragraph contains a hyperlink target named\n\"Norwegian Blue\"::\n\n    Oh yes, the _`Norwegian Blue`.  What's, um, what's wrong with it?\n\nSee `Implicit Hyperlink Targets`_ for the resolution of duplicate\nreference names.\n\n\nFootnote References\n-------------------\n\nSee also: Footnotes_\n\nDoctree element: footnote_reference_.\n\nConfiguration settings:\n`footnote_references <footnote_references setting_>`_,\ntrim_footnote_reference_space_.\n\n.. _trim_footnote_reference_space:\n   ../../user/config.html#trim-footnote-reference-space\n\nStart-string = \"[\", end-string = \"]_\".\n\nEach footnote reference consists of a square-bracketed label followed\nby a trailing underscore.  Footnote labels are one of:\n\n- one or more digits (i.e., a number),\n\n- a single \"#\" (denoting `auto-numbered footnotes`_),\n\n- a \"#\" followed by a simple `reference name`_ (an `autonumber label`_),\n  or\n\n- a single \"*\" (denoting `auto-symbol footnotes`_).\n\nFor example::\n\n    Please RTFM [1]_.\n\n    .. [1] Read The Fine Manual\n\n`Inline markup recognition rules`_ may require whitespace in front of the\nfootnote reference. To remove the whitespace from the output, use an\nescaped whitespace character (see `Escaping Mechanism`_) or set the\ntrim_footnote_reference_space_ configuration setting. Leading whitespace\nis removed by default, if the `footnote_references setting`_ is\n\"superscript\".\n\n\nCitation References\n-------------------\n\nSee also: Citations_\n\nDoctree element: citation_reference_.\n\nStart-string = \"[\", end-string = \"]_\".\n\nEach citation reference consists of a square-bracketed label followed\nby a trailing underscore.  Citation labels are simple `reference\nnames`_ (case-insensitive single words, consisting of alphanumerics\nplus internal hyphens, underscores, and periods; no whitespace).\n\nFor example::\n\n    Here is a citation reference: [CIT2002]_.\n\n\nSubstitution References\n-----------------------\n\nDoctree elements: substitution_reference_, reference_.\n\nStart-string = \"|\", end-string = \"|\" (optionally followed by \"_\" or\n\"__\").\n\nVertical bars are used to bracket the substitution reference text.  A\nsubstitution reference may also be a hyperlink reference by appending\na \"_\" (named) or \"__\" (anonymous) suffix; the substitution text is\nused for the reference text in the named case.\n\nThe processing system replaces substitution references with the\nprocessed contents of the corresponding `substitution definitions`_\n(which see for the definition of \"correspond\").  Substitution\ndefinitions produce inline-compatible elements.\n\nExamples::\n\n    This is a simple |substitution reference|.  It will be replaced by\n    the processing system.\n\n    This is a combination |substitution and hyperlink reference|_.  In\n    addition to being replaced, the replacement text or element will\n    refer to the \"substitution and hyperlink reference\" target.\n\n.. _standalone hyperlink:\n\nStandalone Hyperlinks\n---------------------\n\nDoctree element: reference_.\n\nNo start-string or end-string.\n\nA URI (absolute URI [#URI]_ or standalone email address) within a text\nblock is treated as a general external hyperlink with the URI itself\nas the link's text.  For example::\n\n    See https://www.python.org for info.\n\nwould be marked up in HTML as::\n\n    See <a href=\"https://www.python.org\">https://www.python.org</a> for\n    info.\n\nTwo forms of URI are recognized:\n\n1. Absolute URIs.  These consist of a scheme, a colon (\":\"), and a\n   scheme-specific part whose interpretation depends on the scheme.\n\n   The scheme is the name of the protocol, such as \"http\", \"ftp\",\n   \"mailto\", or \"telnet\".  The scheme consists of an initial letter,\n   followed by letters, numbers, and/or \"+\", \"-\", \".\".  Recognition is\n   limited to known schemes, per the `Official IANA Registry of URI\n   Schemes`_ and the W3C's `Retired Index of WWW Addressing Schemes`_.\n\n   The scheme-specific part of the resource identifier may be either\n   hierarchical or opaque:\n\n   - Hierarchical identifiers begin with one or two slashes and may\n     use slashes to separate hierarchical components of the path.\n     Examples are web pages and FTP sites::\n\n         https://www.python.org\n\n         ftp://ftp.python.org/pub/python\n\n   - Opaque identifiers do not begin with slashes.  Examples are\n     email addresses and newsgroups::\n\n         mailto:someone@somewhere.com\n\n         news:comp.lang.python\n\n   With queries, fragments, and %-escape sequences, URIs can become\n   quite complicated.  A reStructuredText parser must be able to\n   recognize any absolute URI, as defined in RFC2396_ and RFC2732_.\n\n2. Standalone email addresses, which are treated as if they were\n   absolute URIs with a \"mailto:\" scheme.  Example::\n\n       someone@somewhere.com\n\nPunctuation at the end of a URI is not considered part of the URI,\nunless the URI is terminated by a closing angle bracket (\">\").\nBackslashes may be used in URIs to escape markup characters,\nspecifically asterisks (\"*\") and underscores (\"_\") which are valid URI\ncharacters (see `Escaping Mechanism`_ above).\n\n.. [#URI] Uniform Resource Identifier.  URIs are a general form of\n   URLs (Uniform Resource Locators).  For the syntax of URIs see\n   RFC2396_ and RFC2732_.\n\n\nUnits\n=====\n\n(New in Docutils 0.3.10.)\n\nAll measures consist of a positive floating point number in standard\n(non-scientific) notation and a unit, possibly separated by one or\nmore spaces.\n\nUnits are only supported where explicitly mentioned in the reference\nmanuals.\n\n\nLength Units\n------------\n\nThe following length units are supported by the reStructuredText\nparser:\n\n* em (em unit, the element's font size)\n* ex (ex unit, x-height of the element’s font)\n* mm (millimeters; 1 mm = 1/1000 m)\n* cm (centimeters; 1 cm = 10 mm)\n* in (inches; 1 in = 2.54 cm = 96 px)\n* px (pixels, 1 px = 1/96 in) [#]_\n* pt (points; 1 pt = 1/72 in)\n* pc (picas; 1 pc = 1/6 in = 12 pt)\n\nThis set corresponds to the `length units in CSS2`_ (a subset of `length\nunits in CSS3`_).\n\n.. [#] In LaTeX, the default definition is 1 px = 1/72 in (cf. `How to\n   configure the size of a pixel`_ in the LaTeX writer documentation).\n\nThe following are all valid length values: \"1.5em\", \"20 mm\", \".5in\".\n\nLength values without unit are completed with a writer-dependent\ndefault (e.g. \"px\" with HTML, \"pt\" with `latex2e`). See the writer\nspecific documentation in the `user doc`__ for details.\n\n.. _length units in CSS2:\n   https://www.w3.org/TR/CSS2/syndata.html#length-units\n.. _length units in CSS3:\n   https://www.w3.org/TR/css-values-3/#absolute-lengths\n.. _How to configure the size of a pixel:\n   ../../user/latex.html#size-of-a-pixel\n__ ../../user/\n\n\nPercentage Units\n----------------\n\nPercentage values have a percent sign (\"%\") as unit.  Percentage\nvalues are relative to other values, depending on the context in which\nthey occur.\n\n\n----------------\n Error Handling\n----------------\n\nDoctree elements: system_message_,

It is the equivalent of the\nHTML \"cite\" element, and it is expected that HTML writers will\ntypically render \"title_reference\" elements using \"cite\".\n\nSince title references are typically rendered with italics, they are\noften marked up using ``*emphasis*``, which is misleading and vague.\nThe \"title_reference\" element provides accurate and unambiguous\ndescriptive markup.\n\nLet's assume ``:title-reference:`` is the default interpreted text\nrole (see below) for this example::\n\n    `Design Patterns` [GoF95]_ is an excellent read.\n\nThe following document fragment (pseudo-XML_) will result from\nprocessing::\n\n    <paragraph>\n        <title_reference>\n            Design Patterns\n\n        <citation_reference refname=\"gof95\">\n            GoF95\n         is an excellent read.\n\n``:title-reference:`` is the default interpreted text role in the\nstandard reStructuredText parser.  This means that no explicit role is\nrequired.  Applications of reStructuredText may designate a different\ndefault role, in which case the explicit ``:title-reference:`` role\nmust be used to obtain a ``title_reference`` element.\n\n\n.. _pseudo-XML: ../doctree.html#pseudo-xml\n\n\n-------------------\n Specialized Roles\n-------------------\n\n``raw``\n=======\n\n:Aliases: None\n:DTD Element: raw\n:Customization:\n    :Options: class_, format\n    :Content: None\n\n.. WARNING::\n\n   The \"raw\" role is a stop-gap measure allowing the author to bypass\n   reStructuredText's markup.  It is a \"power-user\" feature that\n   should not be overused or abused.  The use of \"raw\" ties documents\n   to specific output formats and makes them less portable.\n\n   If you often need to use \"raw\"-derived interpreted text roles or\n   the \"raw\" directive, that is a sign either of overuse/abuse or that\n   functionality may be missing from reStructuredText.  Please\n   describe your situation in a message to the Docutils-users_ mailing\n   list.\n\n   .. _Docutils-users: ../../user/mailing-lists.html#docutils-user\n\nThe \"raw\" role indicates non-reStructuredText data that is to be\npassed untouched to the Writer.  It is the inline equivalent of the\n`\"raw\" directive`_; see its documentation for details on the\nsemantics.\n\n.. _\"raw\" directive: directives.html#raw-directive\n\nThe \"raw\" role cannot be used directly.  The `\"role\" directive`_ must\nfirst be used to build custom roles based on the \"raw\" role.  One or\nmore formats (Writer names) must be provided in a \"format\" option.\n\nFor example, the following creates an HTML-specific \"raw-html\" role::\n\n    .. role:: raw-html(raw)\n       :format: html\n\nThis role can now be used directly to pass data untouched to the HTML\nWriter.  For example::\n\n    If there just *has* to be a line break here,\n    :raw-html:`<br />`\n    it can be accomplished with a \"raw\"-derived role.\n    But the line block syntax should be considered first.\n\n.. Tip:: Roles based on \"raw\" should clearly indicate their origin, so\n   they are not mistaken for reStructuredText markup.  Using a \"raw-\"\n   prefix for role names is recommended.\n\nIn addition to \"class_\", the following option is recognized:\n\n``format`` : text\n    One or more space-separated output format names (Writer names).\n"

Settings in this file will\n   override corresponding settings in both the system-wide and\n   project-specific configuration files.\n\nIf more than one configuration file is found, all will be read but\nlater entries will override earlier ones.  For example, a \"stylesheet\"\nentry in a user-specific configuration file will override a\n\"stylesheet\" entry in the system-wide file.\n\nThe default implicit config file paths can be overridden by the\n``DOCUTILSCONFIG`` environment variable.  ``DOCUTILSCONFIG`` should\ncontain a colon-separated (semicolon-separated on Windows) sequence of\nconfig file paths to search for; leave it empty to disable implicit\nconfig files altogether.  Tilde-expansion is performed on paths.\nPaths are interpreted relative to the current working directory.\nEmpty path items are ignored.\n\nIn addition, a configuration file may be explicitly specified with the\n``--config`` command-line option.  This configuration file is read after\nthe three implicit ones listed above (or the ones defined by the\n``DOCUTILSCONFIG`` environment variable), and its entries will have\npriority.\n\n.. _Docutils Runtime Settings: ../api/runtime-settings.html\n\n\n-------------------------\nConfiguration File Syntax\n-------------------------\n\nConfiguration files are UTF-8-encoded text files.  The\nConfigParser.py_ module from Python_'s standard library is used to\nread them.  From its documentation:\n\n    The configuration file consists of sections, lead by a \"[section]\"\n    header and followed by \"name: value\" entries, with continuations\n    in the style of `RFC 822`_; \"name=value\" is also accepted.  Note\n    that leading whitespace is removed from values.  ...  Lines\n    beginning with \"#\" or \";\" are ignored and may be used to provide\n    comments.\n\n.. Note:: No format string interpolation is done.\n\nConfiguration file entry names correspond to internal runtime\nsettings.  Underscores (\"_\") and hyphens (\"-\") can be used\ninterchangeably in entry names; hyphens are automatically converted to\nunderscores.\n\nFor on/off switch settings (_`booleans`), the following values are\nrecognized:\n\n:On: \"true\", \"yes\", \"on\", \"1\"\n:Off: \"false\", \"no\", \"off\", \"0\", \"\" (no value)\n\n.. _list:\n\nList values can be comma- or colon-delimited.\n\nstrip_classes_, strip_elements_with_classes_, stylesheet, and\nstylesheet_path use the comma as delimiter,\nwhitespace around list values is stripped. ::\n\n    strip-classes: ham,eggs,\n    strip-elements-with-classes: sugar, salt, flour\n    stylesheet: html4css1.css,\n                math.css,\n                style with spaces.css\n    stylesheet-path: ../styles/my.css, ../styles/funny.css\n\nexpose_internals_, ignore_ and prune_ use the colon as delimiter and do not\nstrip whitespace::\n\n    expose_internals: b:c:d\n\n\nExample\n=======\n\nThis is from the ``tools/docutils.conf`` configuration file supplied\nwith Docutils::\n\n    # These entries affect all processing:\n    [general]\n    source-link: yes\n    datestamp: %Y-%m-%d %H:%M UTC\n    generator: on\n\n    # These entries affect HTML output:\n    [html writers]\n    embed-stylesheet: no\n\n    [html4css1 writer]\n    stylesheet-path: docutils/writers/html4css1/html4css1.css\n    field-name-limit: 20\n\n    [html5 writer]\n    stylesheet-dirs: docutils/writers/html5_polyglot/\n    stylesheet-path: minimal.css, responsive.css\n\nIndividual configuration sections and settings are described in the\nfollowing section.\n\n\n-------------------------------------\nConfiguration File Sections & Entries\n-------------------------------------\n\nBelow are the Docutils runtime settings, listed by config file\nsection.  **Any setting may be specified in any section, but only\nsettings from active sections will be used.**  Sections correspond to\nDocutils components (module name or alias; section names are always in\nlowercase letters).  Each `Docutils application`_ uses a specific set\nof components; corresponding configuration file sections are applied\nwhen the application is used.  Configuration sections are applied in\ngeneral-to-specific order, as follows:\n\n1. `[general]`_\n\n2. `[parsers]`_, parser dependencies, and the section specific to the\n   Parser used (\"[... parser]\").\n\n3. `[readers]`_, reader dependencies, and the section specific to the\n   Reader used (\"[... reader]\").  For example, `[pep reader]`_ depends\n   on `[standalone reader]`_.\n\n4. `[writers]`_, writer family (\"[... writers]\"; if applicable),\n   writer dependencies, and the section specific to the writer used\n   (\"[... writer]\").  For example, `[pep_html writer]`_ depends\n   on `[html writers]`_ and `[html4css1 writer]`_.\n\n5. `[applications]`_, application dependencies, and the section\n   specific to the Application (front-end tool) in use\n   (\"[... application]\").\n\nSince any setting may be specified in any section, this ordering\nallows component- or application-specific overrides of earlier\nsettings.  For example, there may be Reader-specific overrides of\ngeneral settings; Writer-specific overrides of Parser settings;\nApplication-specific overrides of Writer settings; and so on.\n\nIf multiple configuration files are applicable, the process is\ncompleted (all sections are applied in the order given) for each one\nbefore going on to the next.  For example, a \"[pep_html writer]\nstylesheet\" setting in an earlier configuration file would be\noverridden by an \"[html4css1 writer] stylesheet\" setting in a later\nfile.\n\nSome knowledge of Python_ is assumed for some attributes.\n\n.. _ConfigParser.py:\n   https://docs.python.org/3/library/configparser.html\n.. _Python: https://www.python.org/\n.. _RFC 822: https://www.rfc-editor.org/rfc/rfc822.txt\n.. _front-end tool:\n.. _Docutils application: tools.html\n\n\n[general]\n=========\n\nSettings in the \"[general]\" section are always applied.\n\nauto_id_prefix\n--------------\n\nPrefix prepended to all auto-generated `identifier keys` generated within\nthe document, after id_prefix_.

Suggested setup code and usage\n    instructions are provided.\n\n.. contents::\n\nIntroduction\n============\n\nreStructuredText_ is a syntax for simple text files that allows a\ntool set - docutils_ - to extract generic document structure. For\npeople who use Emacs_, there is a package that adds a major mode that\nsupports editing the syntax of reStructuredText_: ``rst.el``. This\ndocument describes the features it provides, and how to setup your\nEmacs_ to use them and how to invoke them.\n\nInstallation\n============\n\nEmacs_ support for reStructuredText_ is implemented as an Emacs_ major\nmode (``rst-mode``) provided by the ``rst.el`` Emacs_ package.\n\nEmacs_ distributions contain ``rst.el`` since version V23.1. However,\na significantly updated version of ``rst.el`` is contained in Emacs_\nV24.3. This document describes the version of ``rst.el`` contained in\nEmacs_ V24.3 and later versions. This version of ``rst.el`` has the\ninternal version V1.4.1.\n\nIf you have Emacs_ V24.3 or later you do not need to install anything\nto get reST support. If you have an Emacs_ between V23.1 and V24.2 you\nmay use the version of ``rst.el`` installed with Emacs_ or install a\nmore recent one locally_ (recommended). In other cases you need to\ninstall ``rst.el`` locally_ to get reST support.\n\nChecking situation\n------------------\n\nHere are some steps to check your situation:\n\n#. In Emacs_ switch to an empty buffer and try ::\n\n     M-x rst-mode\n\n   If this works you have ``rst.el`` installed somewhere. You can see\n   that it works if you find a string ``ReST`` in Emacs' modeline of\n   the current buffer. If this doesn't work you need to install\n   ``rst.el`` yourself locally_.\n\n#. In the buffer you just switched to ``rst-mode`` try ::\n\n     C-h v rst-version\n\n   If this fails you have a version of ``rst.el`` older than\n   V1.1.0. Either you have an old ``rst.el`` locally or you are using\n   an Emacs_ between V23.1 and V24.2. In this case it is recommended\n   that you install a more recent version of ``rst.el`` locally_.\n\n   You may also try ::\n\n     C-h v emacs-version\n\n   to find out your Emacs_ version.\n\n#. Check the version of ``rst.el``\n\n   The content of ``rst-version`` gives you the internal version of\n   ``rst.el``. The version contained in Emacs_ V24.3 and described here\n   is V1.4.0. If you have an older version you may or may not install\n   a more recent version of ``rst.el`` locally_.\n\n.. _locally:\n\nLocal installation\n------------------\n\nIf you decided to install locally please follow these steps.\n\n#. Download ``rst.el``\n\n   Download the most recent published version of ``rst.el`` from\n   https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/tools/editors/emacs/rst.el\n\n#. Put ``rst.el`` to a directory in ``load-path``\n\n   Use ::\n\n     C-h v load-path\n\n   If in the resulting list you find a directory in your home\n   directory put ``rst.el`` in this directory.\n\n   Make sure the directory is one of the first entries in\n   ``load-path``. Otherwise a version of ``rst.el`` which came with\n   Emacs_ may be found before your local version.\n\n   In Emacs_ see the info node ``Init File Examples`` for more\n   information on how to set up your Emacs_ initialization\n   machinery. Try ::\n\n     C-h i\n     mEmacs<Return>\n     sInit File Examples<Return>\n\n#. Enable ``rst-mode``\n\n   Add the following to your Emacs_ initialization setup ::\n\n     (require 'rst)\n\n   After you restarted Emacs_ ``rst.el`` is loaded and ready to be\n   used.\n\nSwitching ``rst-mode`` on\n-------------------------\n\nBy default ``rst-mode`` is switched on for files ending in ``.rst`` or\n``.rest``. If in a buffer you want to switch ``rst-mode`` on manually\nuse ::\n\n  M-x rst-mode\n\nIf you want to use ``rst-mode`` in files with other extensions modify\n``auto-mode-alist`` to automatically turn it on whenever you visit\nreStructuredText_ documents::\n\n   (setq auto-mode-alist\n         (append '((\"\\\\.txt\\\\'\" . rst-mode)\n                   (\"\\\\.rst\\\\'\" . rst-mode)\n                   (\"\\\\.rest\\\\'\" . rst-mode)) auto-mode-alist))\n\nPut the extensions you want in the correct place in the example\nabove. Add more lines if needed.\n\nIf have local variables enabled (try ``C-h v enable-local-variables``\nto find out), you can also add the following at the top of your\ndocuments to trigger rst-mode::\n\n   .. -*- mode: rst -*-\n\nOr this at the end of your documents::\n\n   ..\n      Local Variables:\n      mode: rst\n      End:\n\nKey bindings\n============\n\n``rst-mode`` automatically binds several keys for invoking special\nfunctions for editing reStructuredText_. Since ``rst-mode`` contains a\nlot of functionality most key bindings consist of three\nkeystrokes.\n\nFollowing the Emacs_ conventions for major modes the key bindings of\n``rst-mode`` start with ``C-c C-<letter>``. The second key stroke\nselects a group of key bindings:\n\nC-c C-a\n  Commands to adjust the section headers and work with the hierarchy\n  they build.\n\nC-c C-c\n  Commands to compile the current reStructuredText_ document to\n  various output formats.\n\nC-c C-l\n  Commands to work with lists of various kinds.\n\nC-c C-r\n  Commands to manipulate the current region.\n\nC-c C-t\n  Commands to create and manipulate a table of contents.\n\nAt any stage of typing you may use ``C-h`` to get help on the\navailable key bindings. I.e. ``C-c C-h`` gives you help on all key\nbindings while ``C-c C-r C-h`` gives you help on the commands for\nregions. This is handy if you forgot a certain key binding.\n\nAdditional key bindings which have a certain meaning in other Emacs_\nmodes are reused in ``rst-mode`` so you don't have to learn a\ndifferent set of key bindings for editing reStructuredText_.\n\nIn ``rst-mode`` try ::\n\n  C-h m\n\nto list all mode specific key bindings. Most of the key bindings are\ndescribed in this tutorial.\n\n.. note:: The key bindings have been completely revamped in ``rst.el``\n          V1.0.0. This was necessary to make room for new\n          functionality. Some of the old bindings still work but give\n          a warning to use the new binding. In the output of ``C-h m``\n          these bindings show up as ``rst-deprecated-...``. The old\n          bindings will be removed completely in a later version.\n\nSection Adornments\n==================\n\n``rst-mode`` recognizes the section adornments building the section\nhierarchy of the document. Section adornments are the underlines or\nunder- and overlines used to mark a section title. There are a couple\nof commands to work with section adornments. These commands are bound\nto key bindings starting with ``C-c C-a``.\n\nAdjusting a Section Title\n-------------------------\n\nThere is a function that helps a great deal to maintain these\nadornments: ``rst-adjust`` (bound to ``C-c C-a C-a``, ``C-c C-=``, and\n``C-=``). This function is a Swiss army knife that can be invoked\nrepeatedly and whose behavior depends on context:\n\n#. If there is an incomplete adornment, e.g. ::\n\n      My Section Title\n      ==\n\n   invocation will complete the adornment. It can also be used to\n   adjust the length of the existing adornment when you need to edit\n   the title.\n\n#. If there is no section adornment at all, by default an adornment of\n   the same level as the last encountered section level is added. You\n   can simply enter a few characters of the title and invoke the\n   function to create the section adornment.\n\n   The variable ``rst-new-adornment-down`` can be customized to create\n   one level lower adornments than the previous section title instead\n   of keeping the level.\n\n#. If there is already a section adornment, it is promoted one level\n   up. You can invoke it like this repeatedly to cycle the title\n   through the hierarchy of existing adornments.\n\nInvoking the function with a negative prefix argument, e.g. ``C--\nC-=``, will effectively reverse the direction of adornment cycling.\nTo alternate between underline-only and over-and-under styles, you can\nuse a regular prefix argument, e.g. ``C-u C-=``. See the\ndocumentation of ``rst-adjust`` for more description of the prefix\narguments to alter the behavior of the function.\n\nPromoting and Demoting Many Sections\n------------------------------------\n\nWhen you are re-organizing the structure of a document, it can be\nuseful to change the level of a number of section titles. The same\nkey binding can be used to do that: if the region is active when the\nbinding is invoked, all the section titles that are within the region\nare promoted accordingly (or demoted, with negative prefix argument).\n\nRedoing All the Adornments to Your Taste\n----------------------------------------\n\nIf you open someone else's file and the adornments it contains are\nunfamiliar, you may want to readjust them to fit your own preferred\nhierarchy of adornments. This can be difficult to perform by hand.\nHowever, you can do this easily by invoking\n``rst-straighten-adornments`` (``C-c C-a C-s``), which operates on the\nentire buffer.\n\nCustomizations for Adornments\n-----------------------------\n\nYou can customize the variable ``rst-preferred-adornments`` to a list\nof the adornments that you like to use for documents.\n\nIf you prefer adornments according to\nhttp://sphinx-doc.org/rest.html#sections you may customize it to end\nup with a value like this::\n\n  ((35 over-and-under 0) ; ?#\n   (42 over-and-under 0) ; ?*\n   (61 simple 0) ; ?=\n   (45 simple 0) ; ?-\n   (94 simple 0) ; ?^\n   (34 simple 0)) ; ?\"\n\nThis will become the default in a later version of ``rst.el``.\n\nIf you set ``rst-preferred-adornments`` to nil resembling the empty\nlist only the section adornment found in the buffer will be used.\n\nViewing the Hierarchy of Section Adornments\n-------------------------------------------\n\nYou can visualize the hierarchy of the section adornments in the\ncurrent buffer by invoking ``rst-display-adornments-hierarchy``, bound\non ``C-c C-a C-d``. A temporary buffer will appear with fake section\ntitles rendered in the style of the current document. This can be\nuseful when editing other people's documents to find out which section\nadornments correspond to which levels.\n\nMovement and Selection\n======================\n\nMovement and Selection for Sections\n-----------------------------------\n\nYou can move the cursor between the different section titles by using\nthe ``rst-backward-section`` (``C-M-a``) and ``rst-forward-section``\n(``C-M-e``). To mark the section that cursor lies in, use\n``rst-mark-section`` (``C-M-h``).\n\nThe key bindings are modeled after other modes with similar\nfunctionality.\n\nMovements and Selection for Text Blocks\n---------------------------------------\n\nThe understanding of reStructuredText_ of ``rst-mode`` is used to set\nall the variables influencing Emacs' understanding of paragraphs. Thus\nall operations on paragraphs work as usual. For instance\n``forward-paragraph`` (``M-}``) works as usual.\n\nIndenting and Filling\n=====================\n\nIndentation of text plays a major role in the syntax of\nreStructuredText_. It is tedious to maintain the indentation\nmanually. ``rst-mode`` understands most of the structure of\nreStructuredText_ allowing for sophisticated indentation and filling\nsupport described in this section.\n\nIndenting Text Blocks\n---------------------\n\n``rst-mode`` supports indentation of text blocks by the command\n``rst-shift-region`` (``C-c C-r TAB``). Mark a region and use ``C-c\nC-r TAB`` to indent all blocks one tab to the right. Use ``M-- C-c C-r\nTAB`` to indent the region one tab to the left.\n\nYou may use arbitrary prefix arguments such as ``M-2`` or ``M-- 2`` to\ndetermine the number of tabs you want to indent. A prefix of ``M-0``\nremoves all indentation in the active region.\n\nA tab is an indentation making sense for the block at hand in\nreStructuredText_ syntax. In some cases the exact indentation depends\non personal taste. You may customize a couple of variables ``M-x\ncustomize-group<RET> rst-indent<RET>`` to match your taste.\n\nIndenting Lines While Typing\n----------------------------\n\nIn Emacs_ the ``TAB`` key is often used for indenting the current\nline. ``rst-mode`` implements this for the sophisticated indentation\nrules of reStructuredText_. Pressing ``TAB`` cycles through the\npossible tabs for the current line. In the same manner\n``newline-and-indent`` (``C-j``) indents the new line properly.\n\nThis is very handy while writing lists. Consider this\nreStructuredText_ bullet list with the cursor at ``@``::\n\n  * Level 1\n\n    * Level 2@\n\nType ``C-j`` twice to get this::\n\n  * Level 1\n\n    * Level 2\n\n      @\n\nNow you an enter text at this level, or start a new list item by\ntyping another ``*``. Or you may type ``TAB`` to reduce the\nindentation once::\n\n  * Level 1\n\n    * Level 2\n\n    @\n\nTyping another ``TAB`` gets you to the first level::\n\n  * Level 1\n\n    * Level 2\n\n  @\n\n.. note:: Since Emacs_ V24.4 ``electric-indent-mode`` is globally on.\n          This breaks indentation in ``rst-mode`` and renders\n          ``rst-mode`` mostly useless. This is fixed in V1.4.1 of\n          ``rst-mode``.\n\n          A quick fix for older versions of ``rst.el`` is to add the\n          following line at the end of the ``(define-derived-mode\n          rst-mode ...`` block in your copy of ``rst.el``::\n\n            (setq electric-indent-inhibit t)\n\n          You may also install V1.4.1 or newer locally_.\n\nFilling\n-------\n\n``rst-mode`` understanding the indentation rules of reStructuredText_\nalso supports filling paragraphs. Just use ``fill-paragraph``\n(``M-q``) as you do in other modes.\n\nOperating on Lists\n==================\n\nLists are supported in various flavors in reStructuredText_.\n``rst-mode`` understands reStructuredText_ lists and offers some\nsupport for operating on lists. Key bindings for commands for\noperating on lists start with ``C-c C-l``.\n\nPlease note that so far definition lists are not explicitly supported\nby ``rst-mode``.\n\nBulleted and Enumerated Lists\n-----------------------------\n\nIf you have a couple of plain lines you want to turn into an\nenumerated list you can invoke ``rst-enumerate-region`` (``C-c C-l\nC-e``). For example, the following region ::\n\n  Apples\n\n  Oranges\n\n  Bananas\n\nbecomes ::\n\n  1. Apples\n\n  2. Oranges\n\n  3. Bananas\n\n``rst-bullet-list-region`` (``C-c C-l C-b``) does the same, but\nresults in a bullet list ::\n\n  * Apples\n\n  * Oranges\n\n  * Bananas\n\nBy default, each paragraph starting on the leftmost line in the\nhighlighted region will be taken to be a single list or enumeration\nitem, for example, enumerating the following::\n\n   An apple a day\n   keeps the doctor away.\n\n   But oranges\n   are tastier than apples.\n\n   If you preferred bananas\n   you may be\n   a monkey.\n\nWill result in::\n\n   1. An apple a day\n      keeps the doctor away.\n\n   2. But oranges\n      are tastier than apples.\n\n   3. If you preferred bananas\n      you may be\n      a monkey.\n\nIf you would like to enumerate each of the lines, use a prefix\nargument on the preceding commands, e.g.::\n\n  Apples\n  Oranges\n  Bananas\n\nbecomes::\n\n  * Apples\n  * Oranges\n  * Bananas\n\nStraightening Existing Bullet List Hierarchies\n----------------------------------------------\n\nIf you invoke ``rst-straighten-bullets-region`` (``C-c C-l C-s``), the\nexisting bullets in the active region will be replaced to reflect\ntheir respective level. This does not make a difference in the\ndocument structure that reStructuredText_ defines, but looks better\nin, for example, if all of the top-level bullet items use the\ncharacter ``-``, and all of the 2nd level items use ``*``, etc.\n\nInserting a List Item\n---------------------\n\nTo start a new list you may invoke ``rst-insert-list`` (``C-c C-l\nC-i``). You may choose from an item style supported by\nreStructuredText_.\n\nYou may also invoke ``rst-insert-list`` at the end of a list item. In\nthis case it inserts a new line containing the markup for the a list\nitem on the same level.\n\nOperating on Other Text Blocks\n==============================\n\nCreating and Removing Line Blocks\n---------------------------------\n\nTo create line blocks, first select the region to convert and invoke\n``rst-line-block-region`` ``C-c C-r C-l``. For example, the following\n::\n\n  Apples\n  Oranges\n  Bananas\n\nbecomes ::\n\n  | Apples\n  | Oranges\n  | Bananas\n\nThis works even if the region is indented. To remove line blocks,\nselect a region and invoke with a prefix argument.\n\nCommenting a Region of Text\n---------------------------\n\n``rst-mode`` understands reStructuredText_ comments. Use\n``comment-dwim`` (``M-;``) to work on comments as usual::\n\n  Apples\n  Oranges\n  Bananas\n\nbecomes::\n\n  ..\n     Apples\n     Oranges\n     Bananas\n\nTo remove a comment you have to tell this to ``comment-dwim``\nexplicitly by using a prefix argument (``C-u M-;``).\n\nPlease note that only indented comments are supported properly by the\nparts of ``comment-dwim`` working on regions.\n\n.. _Conversion:\n\nConverting Documents from Emacs\n===============================\n\n``rst-mode`` provides a number of functions for running documents\nbeing edited through the docutils tools. The key bindings for these\ncommands start with ``C-c C-c``.\n\nThe main generic function is ``rst-compile`` (``C-c C-c C-c``). It\ninvokes a compilation command with the correct output name for the\ncurrent buffer and then invokes Emacs' compile function. It also looks\nfor the presence of a ``docutils.conf`` configuration file in the\nparent directories and adds it to the command line options. There is also\n``rst-compile-alt-toolset`` (``C-c C-c C-a``) in case you often need\nrun your document in a second toolset.\n\nYou can customize the commands being used by setting\n``rst-compile-primary-toolset`` and ``rst-compile-secondary-toolset``.\n\nOther commands are available for other formats:\n\n* ``rst-compile-pseudo-region`` (``C-c C-c C-x``)\n\n  When crafting documents, it is often convenient to view which data\n  structures docutils will parse them into. You can use to run the\n  active region through ``rst2pseudoxml.py`` and have the output\n  automatically be displayed in a new buffer.\n\n* ``rst-compile-pdf-preview`` (``C-c C-c C-p``)\n\n  Convert the current document to PDF and launch a viewer on the\n  results.\n\n* ``rst-compile-slides-preview`` (``C-c C-c C-s``): Convert the\n  current document to S5 slides and view in a web browser.\n\nImenu Support\n=============\n\nUsing Imenu\n-----------\n\nEmacs_ has a package called ``imenu``. ``rst-mode`` supports Imenu by\nadding a function to convert the structure of a reStructuredText_\nbuffer to an Imenu index. Thus you can use invoke ``imenu`` (``M-x\nimenu``) to navigate through the section index or invoke\n``imenu-add-to-menubar`` (``M-x imenu-add-to-menubar``) to add an\nImenu menu entry to Emacs' menu bar.\n\nUsing which function\n--------------------\n\nAs a side effect of Imenu support the ``which-func`` package is also\nsupported. Invoke ``which-function-mode`` (``M-x\nwhich-function-mode``) to add the name of the current section to the\nmode line. This is especially useful if you navigate through documents\nwith long sections which do not fit on a single screen.\n\nUsing the Table of Contents\n===========================\n\nThe sections in a reStructuredText_ document can be used to form a\ntable of contents. ``rst-mode`` can work with such a table of contents\nin various forms. Key bindings for these commands start with ``C-c\nC-t``.\n\nNavigating Using the Table of Contents\n--------------------------------------\n\nWhen you are editing long documents, it can be a bit difficult to\norient yourself in the structure of your text. To that effect, a\nfunction is provided that presents a hierarchically indented table of\ncontents of the document in a temporary buffer, in which you can\nnavigate and press ``Return`` to go to a specific section.\n\nInvoke ``rst-toc`` (``C-c C-t C-t``). It presents a temporary buffer\nthat looks something like this::\n\n  Table of Contents:\n  Debugging Meta-Techniques\n    Introduction\n    Debugging Solution Patterns\n      Recognize That a Bug Exists\n      Subdivide and Isolate\n      Identify and Verify Assumptions\n      Use a Tool for Introspection\n      Change one thing at a time\n      Learn about the System\n    Understanding a bug\n    The Basic Steps in Debugging\n    Attitude\n      Bad Feelings\n      Good Feelings\n    References\n\nWhen you move the cursor to a section title and press ``RET`` or ``f``\nor click with ``button1`` on a section title, the temporary buffer\ndisappears and you are left with the cursor positioned at the chosen\nsection. Clicking with ``button2`` jumps to the respective section but\nkeeps the toc buffer. You can use this to look at the various section\nheaders quickly. Use ``q`` in this buffer to just quit it without\nmoving the cursor in the original document. Use ``z`` to zap the\nbuffer altogether.\n\nInserting a Table of Contents\n-----------------------------\n\nOftentimes in long text documents that are meant to be read directly,\na table of contents is inserted at the beginning of the text. In\nreStructuredText_ documents, since the table of contents is\nautomatically generated by the parser with the ``.. contents::``\ndirective, people generally have not been adding an explicit table of\ncontents to their source documents, and partly because it is too much\ntrouble to edit and maintain.\n\nThe Emacs_ support for reStructuredText_ provides a function to insert\nsuch a table of contents in your document. Since it is not meant to\nbe part of the document text, you should place such a table of\ncontents within a comment, so that it is ignored by the parser. This\nis the favored usage::\n\n  .. contents::\n  ..\n      1  Introduction\n      2  Debugging Solution Patterns\n        2.1  Recognize That a Bug Exists\n        2.2  Subdivide and Isolate\n        2.3  Identify and Verify Assumptions\n        2.4  Use a Tool for Introspection\n        2.5  Change one thing at a time\n        2.6  Learn about the System\n      3  Understanding a bug\n      4  The Basic Steps in Debugging\n      5  Attitude\n        5.1  Bad Feelings\n        5.2  Good Feelings\n      6  References\n\nJust place the cursor at the top-left corner where you want to insert\nthe TOC and invoke the function ``rst-toc-insert`` with ``C-c C-t\nC-i``. The table of contents will display all the section titles that\nare under the location where the insertion occurs. This way you can\ninsert local table of contents by placing them in the appropriate\nlocation.\n\nYou can use a numeric prefix argument to limit the depth of rendering\nof the TOC.\n\nYou can customize the look of the TOC by setting the values of the\nfollowing variables: ``rst-toc-indent``, ``rst-toc-insert-style``,\n``rst-toc-insert-max-level``.\n\nMaintaining the Table of Contents Up-to-date\n--------------------------------------------\n\nOne issue is that you will probably want to maintain the inserted\ntable of contents up-to-date. ``rst-toc-update`` (``C-c C-t C-u``)\nwill automatically update an inserted table of contents following a\n``.. contents::`` directive laid out like the example above.\n\nSyntax Highlighting via Font-Lock\n=================================\n\n``rst-mode`` provides syntax highlighting for nearly all to\nreStructuredText_ constructs.\n\nUse ``customize-group rst-faces`` to customize the faces used for\nfont-locking.\n\nCustomization\n=============\n\nSome aspects of ``rst-mode`` can be configured through the\ncustomization feature of Emacs_. Try ::\n\n  M-x customize-group<RETURN>rst\n\nfor all customizations or use the respective menu entry. Those\ncustomizations which are useful for many people are described in this\nsection.\n\nCustomizing Section Title Formatting\n------------------------------------\n\nFor a couple of things the reStructuredText_ syntax offers a choice of\noptions on how to do things exactly. Some of these choices influence\nthe operation of ``rst.el`` and thus can be configured. The\ncustomizations are contained in the ``rst-adjust`` group.\n\nAmong these things is the exact layout of section adornments. In fact\nreStructuredText_ prescribes only the characters and how these\ncharacters must be used but the exact use of concrete adornments may\nbe different in every source file. Using the customization option\n``rst-preferred-adornments`` you can tell ``rst-mode`` on the exact\nsequence of adornments you prefer to markup the different levels of\nsections headers.\n\nFinally the title text of over-and-under adornments may be indented in\nreStructuredText_. ``rst-default-indent`` tells ``rst-mode`` how many\npositions a over-and-under adornment should be indented when toggling\nfrom simple adornment and in case a consistent indentation throughout\nthe whole buffer for such adornment is needed.\n\nCustomizing Indentation\n-----------------------\n\nreStructuredText_ uses indentation a lot to signify a certain meaning.\nIn some cases the exact amount of indentation is prescribed by the\nsyntax while in some cases the exact indentation is not fixed. The\ncustomization group ``rst-indent`` allows to customize the amount of\nindentation in these cases.\n\nIn field lists the content of a field needs to be indented relative to\nthe field label. ``rst-indent-field`` tells ``rst-mode`` the amount of\nindentation to use for field content. A value of zero always indents\naccording to the content after the field label.\n\nThe indentation of literal blocks is controlled by\n``rst-indent-literal-normal`` and ``rst-indent-literal-minimized``.\nThe first is used when the leading literal tag (``::``) appears alone\non a line. The second is used when the minimized style is used where\nthe literal tag follows some text.\n\nThe indentation of comments is controlled by ``rst-indent-comment``.\nOf course this makes only sense for the indented comments of\nreStructuredText_.\n\nCustomization option ``rst-indent-width`` gives the default\nindentation when there are no other hints on what amount of\nindentation to use.\n\nCustomizing Faces\n-----------------\n\nThe faces used for font-locking can be defined in the ``rst-faces``\ncustomization group. The customization options ending in ``-face`` are\nonly there for backward compatibility so please leave them as they\nare.\n\nreStructuredText_ sets no limit on the nesting of sections. By default\nthere are six levels of fontification defined. Section titles deeper\nthan six level have no special fontification - only the adornments are\nfontified. The exact mapping from a level to a face is done by by\n``rst-adornment-faces-alist``, however. So if you need fontification\ndeeper than six levels you may want to customize this option. You may\nalso want to customize it if you like the general idea of section\ntitle fontification in ``rst-mode`` but for instance prefer a reversed\norder.\n\nCustomizing Conversion\n----------------------\n\nConversion_ can be customized by the customization options in the\ncustomization group ``rst-compile``.\n\nIf some conversion does not work as expected please check\nthe variable ``rst-compile-toolsets`` ::\n\n  M-x customize-option<RETURN>rst-compile-toolsets\n\nThis variable defines the commands and other details used for\nconversion. In case of problems please check that the commands are\neither available or customize them to what is available in your\nenvironment.\n\n.. note:: There are some options in V1.4.1 of ``rst.el`` which should\n          be customization options but are not yet. Customization\n          support will be added in a later version.\n\n.. note:: Please note that there is a package ``rst2pdf`` based on the\n          ReportLab library. Please note that the command of this\n          package requires an additional ``-o`` for naming the output\n          file. This breaks the usual conventions employed by Docutils\n          tools. ``rst-mode`` V1.4.1 does not support this directly.\n\nOther Customizations\n--------------------\n\n``rst-preferred-bullets`` can be customized to hold your preferred set\nof bullets to use for bulleted lists.\n\n``rst-mode-hook`` is a normal major mode hook which may be customized.\nIt is run if you enter ``rst-mode``.\n\nRelated aspects\n===============\n\nThis section covers some general aspects using Emacs_ for editing\nreStructuredText_ source. They are not directly related to\n``rst-mode`` but may enhance your experience.\n\n``text-mode`` Settings\n----------------------\n\nConsult the Emacs_ manual for more ``text-mode`` customizations. In\nparticular, you may be interested in setting the following variables,\nfunctions and modes that pertain somewhat to ``text-mode``:\n\n* ``indent-tabs-mode``\n* ``colon-double-space``\n* ``sentence-end-double-space``\n* ``auto-fill-mode``\n* ``auto-mode-alist``\n\nEditing Tables: Emacs table mode\n--------------------------------\n\nYou may want to check out `Emacs table mode`_ to create an edit\ntables, it allows creating ASCII tables compatible with\nreStructuredText_.\n\n.. _Emacs table mode: http://table.sourceforge.net/\n\nCharacter Processing\n--------------------\n\nSince reStructuredText punts on the issue of character processing,\nhere are some useful resources for Emacs_ users in the Unicode world:\n\n* `xmlunicode.el and unichars.el from Norman Walsh\n  <http://nwalsh.com/emacs/xmlchars/index.html>`__\n\n* `An essay by Tim Bray, with example code\n  <http://www.tbray.org/ongoing/When/200x/2003/09/27/UniEmacs>`__\n\n* For Emacs_ users on Mac OS X, here are some useful useful additions\n  to your .emacs file.\n\n  - To get direct keyboard input of non-ASCII characters (like\n    \"option-e e\" resulting in \"é\" [eacute]), first enable the option\n    key by setting the command key as your meta key::\n\n        (setq mac-command-key-is-meta t) ;; nil for option key\n\n    Next, use one of these lines::\n\n        (set-keyboard-coding-system 'mac-roman)\n        (setq mac-keyboard-text-encoding kTextEncodingISOLatin1)\n\n    I prefer the first line, because it enables non-Latin-1 characters\n    as well (em-dash, curly quotes, etc.).\n\n  - To enable the display of all characters in the Mac-Roman charset,\n    first create a fontset listing the fonts to use for each range of\n    characters using charsets that Emacs_ understands::\n\n      (create-fontset-from-fontset-spec\n       \"-apple-monaco-medium-r-normal--10-*-*-*-*-*-fontset-monaco,\n        ascii:-apple-monaco-medium-r-normal--10-100-75-75-m-100-mac-roman,\n        latin-iso8859-1:-apple-monaco-medium-r-normal--10-100-75-75-m-100-mac-roman,\n        mule-unicode-0100-24ff:-apple-monaco-medium-r-normal--10-100-75-75-m-100-mac-roman\")\n\n    Latin-1 doesn't cover characters like em-dash and curly quotes, so\n    \"mule-unicode-0100-24ff\" is needed.\n\n    Next, use that fontset::\n\n        (set-frame-font \"fontset-monaco\")\n\n  - To enable cooperation between the system clipboard and the Emacs_\n    kill ring, add this line::\n\n        (set-clipboard-coding-system 'mac-roman)\n\n  Other useful resources are in `Andrew Choi's Emacs 21 for Mac OS X\n  FAQ <http://members.shaw.ca/akochoi-emacs/stories/faq.html>`__.\n\nCredits\n=======\n\nPart of the original code of ``rst.el`` has been written by Martin\nBlais and David Goodger and Wei-Wei Guo.

Another line of argument suggests that even under the\n      most optimistic of projections, so tiny a fraction of the web will\n      ever be written in Polyglot that there's no practical benefit to\n      pursuing it as a general strategy for consuming documents from the\n      web. If you want to consume HTML content, use an HTML parser that\n      produces an XML-compatible DOM or event stream.\n\n      -- https://www.w3.org/TR/html-xml-tf-report/#conclusions\n\n  Further development\n\n  On 2016-05-25, David Goodger wrote:\n\n  > In addition, I'd actually like to see the HTML writer(s) with\n  > fully-parameterized classes, i.e. removing hard-coded *classes* as well as\n  > formatting.

It\nis most often used for medium-to-large technical or scientific documents but\nit can be used for almost any form of publishing. There exists a wide\nselection of `LaTeX Documentation on the net`_ and `books on LaTeX and\nrelated topics`_. For an introduction to LaTeX see, e.g., `LaTeX2e for\nauthors`_.\n\n__ http://www.latex-project.org/\n.. _LaTeX2e for authors:\n   http://www.latex-project.org/guides/usrguide.pdf\n.. _LaTeX Documentation on the net:\n   http://www.latex-project.org/guides/\n.. _books on LaTeX and related topics:\n   http://www.latex-project.org/guides/books.html\n\n\n.. _LaTeX packages:\n\nLaTeX document classes and packages\n-----------------------------------\n\nUnlike HTML with CSS, LaTeX uses one common language for markup and style\ndefinitions. Separation of content and style is realized by collecting style\ndefinitions in LaTeX classes and packages, or the\n`document preamble <LaTeX preamble_>`_.\n\nLaTeX document classes and packages (similar to Python modules or C\nlibraries) provide means to extend or modify the LaTeX language by\nredefining macros or providing new ones.\n\nUsing the `document class`_ and `style sheet`_ configuration options, you\ncan select from a *huge* selection of classes and packages (standard as well\nas user contributed) coming with your TeX distribution or available at\nCTAN_ as well as custom style sheets.\n\n.. _CTAN: http://www.ctan.org\n\n\nDocutils specific LaTeX macros\n------------------------------\n\nSome Docutils objects have no LaTeX counterpart, they will be typeset\nusing a Docutils specific LaTeX *macro* (command, environment, or\nlength) to allow customization. By convention, special macros use the\nprefix ``\\DU``\\ [#]_.\n\nThe `docutils.sty`_ LaTeX package providing required definitions is\npart of Docutils ≥ 0.17 and available on CTAN since 2020-09-04.\nThe generated LaTeX documents should be kept processable by a standard LaTeX\ninstallation. Therefore fallback definitions are included after the `custom\nstyle sheets`_, if a macro is required in the document and\nthe `stylesheet`_ setting does not include \"docutils\".\n\n* Custom `style sheets`_ can define alternative implementations with\n  ``\\newcommand``, ``\\newenvironment``, and ``\\newlength`` followed by\n  ``\\setlength``.\n\n* Definitions with `raw LaTeX`_ are part of the document body. Use\n  ``\\def``, ``\\renewcommand`` or ``\\renewenvironment``, and ``\\setlength``.\n\nSee the test output standalone_rst_latex.tex_ for an example of the fallback\ndefinitions and their use in the document.\n\n.. [#] DU for Documentation Utilities = Docutils\n\n.. _docutils.sty: https://ctan.org/pkg/docutils\n\n\n\nLength units\n------------\n\nLaTeX supports all `length units`_ defined for Docutils plus the\nfollowing less common units:\n\n:pt: typewriter's (or LaTeX) point (1 pt = 1/72.27 in)\n:dd: didôt (1 dd = 1238/1157 pt)\n:cc: cîcero (1 cc = 12 dd)\n:sp: scaled point (1sp = 1/65536pt)\n\n.. attention:: Different definitions of the unit \"pt\"!\n\n   * In Docutils (as well as CSS) the unit symbol \"pt\" denotes the\n     `Postscript point` or `DTP point`.\n\n   * LaTeX uses \"pt\" for the `LaTeX point`, which is unknown to Docutils and\n     0.3 % smaller.\n\n   * The `DTP point` is available in LaTeX as \"bp\" (big point):\n\n       1 pt = 1/72.25 in < 1 bp  = 1/72 in\n\n   Lengths specified in the document with unit \"pt\" will be given the\n   unit \"bp\" in the LaTeX source.\n\n   In `raw LaTeX`_ and `custom style sheets`_, the `DTP point` must be\n   specified as \"bp\", while \"pt\" is interpreted as `LaTeX point`.\n\nThe default length unit (added by Docutils to length specifications\nwithout unit) is the \"DTP point\".\n\n.. _length units: ../ref/rst/restructuredtext.html#length-units\n\n\nPDF generation\n==============\n\nIn most cases, LaTeX code is not the desired end-format of the document.\nLaTeX offers many ways to generate PDF documents from the LaTeX\nsource, including:\n\n_`pdflatex`\n  Generates a PDF document directly from the LaTeX file.\n  Export your document with the _`LaTeX2e writer` (writer\n  name \"``latex``\", frontend tool rst2latex.py_).\n\n_`xelatex` or _`lualatex`\n  The `XeTeX`_ and LuaTeX_ engines work with input files in UTF-8 encoding\n  and system fonts. Export your document with the _`XeLaTeX writer` (writer\n  name \"``xetex``\", frontend tool rst2xetex.py_).\n\nYou may need to call latex two or three times to get internal references\ncorrect.\n\n.. _documentoptions: config.html#documentoptions\n.. _xetex: http://tug.org/xetex/\n.. _luatex: http://luatex.org/\n.. _rst2latex.py: tools.html#rst2latex-py\n.. _rst2xetex.py: tools.html#rst2xetex-py\n\n_`rubber`\n  The Rubber__ wrapper for LaTeX and friends can be used to automatically\n  run all programs the required number of times and delete \"spurious\" files.\n  This includes processing bibliographic references or indices, as well as\n  compilation or conversion of figures.\n\n__ https://gitlab.com/latex-rubber/rubber/\n\n\nConfiguration\n=============\n\n.. contents:: :local:\n\n.. _option:\n\nOptions/Settings\n----------------\n\nOptions can be specified as\n\n* command-line options, or\n\n* configuration settings.\n\nRun ``rst2latex.py --help`` to get a list of available options;\nsee `Docutils Configuration`_ for details.\n\n.. _Docutils Configuration: config.html\n\nClasses\n-------\n\nThe `\"classes\" attribute`_ is one of the common attributes, shared by all\nDocutils elements.\nIn HTML, the common use is to provide selection criteria for style rules in\nCSS stylesheets. As there is no comparable framework for LaTeX, Docutils\nemulates some of this behaviour via `Docutils specific LaTeX macros`_.\nDue to LaTeX limitations, class arguments are ignored for\nsome elements (e.g. a rubric_).\n\n*Inline elements*\n  are handled via the ``\\DUrole{}`` macro that calls the optional styling\n  command ``\\DUrole«classargument»`` with one argument (the role content).\n  See `custom interpreted text roles`_.\n\n*Block level elements*\n  are wrapped in \"class environments\":\n  ``\\begin{DUclass}`` calls the optional styling command\n  ``\\DUCLASS«classargument»{}``, ``\\end{DUclass}`` tries\n  ``\\endDUCLASS«classargument»``.\n\nCustomization is done by defining matching macros or environments.\n\nExample 1:\n  Use small caps font inside elements with class value \"custom\".\n\n  *Inline elements*\n    The LaTeX function ``\\textsc`` sets the argument in small caps::\n\n      \\newcommand{\\DUrolecustom}[1]{\\textsc{#1}}\n\n  *Block-level elements*\n    The LaTeX directive (macro without argument) ``\\scshape`` switches to\n    the small caps font. Its effect is confined to the wrapper ``DUclass``\n    environment::\n\n      \\newcommand*{\\DUCLASScustom}{\\scshape}\n\nExample 2:\n  It is even possible to locally redefine other LaTeX macros, e.g. to\n  turn bullet lists with class value \"enumerateitems\" into enumerated\n  lists::\n\n    \\newcommand*{\\DUCLASSenumerateitems}{%\n      \\renewenvironment{itemize}{\\begin{enumerate}}%\n                                {\\end{enumerate}}%\n    }\n\n.. rubric:: Notes\n\n* Class arguments may contain numbers and hyphens, which need special\n  treatment in LaTeX command names (see `class directive`_). The commands\n  ``\\csname`` and ``\\endcsname`` or the special command ``\\@namedef`` can\n  help with the definition of corresponding macros or environments, e.g.::\n\n    \\expandafter\\newcommand\\csname gg1\\endcsname{Definition of gg1.}\n\n  or ::\n\n    \\makeatletter\n    \\@namedef{DUCLASSadmonition-test}{…}\n    \\makeatother\n\n* Elements can have multiple class arguments. In contrast to HTML/CSS, the\n  order of the class arguments cannot be ignored in LaTeX\n\n* Class handling differs for some elements and class values:\n\n  * Class argument values starting with ``align-`` are transformed to\n    \"align\" argument values. Class argument values starting with\n    ``language-`` set the elements language property.\n\n  * The table element recognizes some special class values. See section\n    `table style`_.\n\n  * If the legacy-class-functions_ setting is True, the special macros\n    ``\\DUadmonition`` and ``\\DUtitle`` are written with a comma separated\n    list of class values as optional argument.\n\n.. _\"classes\" attribute: ../ref/doctree.html#classes\n.. _legacy-class-functions: config.html#legacy-class-functions\n\nLaTeX code\n----------\n\nCustom LaTeX code can be placed in `style sheets`_, the\n`LaTeX preamble`_, the document body (`raw LaTeX`_), or custom templates_.\n\nThe functional tests that come with Docutils, can serve as example.\n\ninput:\n  standalone_rst_latex.txt_ (includes files from `tests/functional/input/data`_)\nexpected output:\n  standalone_rst_latex.tex_\n\n.. _standalone_rst_latex.txt:\n  https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/input/standalone_rst_latex.txt\n.. _tests/functional/input/data:\n  https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/input/data\n.. _standalone_rst_latex.tex:\n   https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/expected/standalone_rst_latex.tex\n\n\n.. _style sheet:\n.. _custom style sheets:\n\nStyle sheets\n````````````\n\nA common way of LaTeX customization is the preparation of custom style\nsheets, either as simple files with LaTeX code snippets or as home-made\n`LaTeX packages`_ (see the clsguide_ for an introduction on LaTeX\npackage writing).\n\nOptions:\n  stylesheet_\n\n  It is possible to specify multiple style sheets and mix `LaTeX\n  packages`_ with custom style sheets.\n\nYou cannot specify package options with the stylesheet_ setting. If\nyou need to pass options to the package, use the ``\\usepackage``\ncommand in the `LaTeX preamble`_ or a custom style sheet.\n\nExample 1:\n  Select Latin Modern fonts with the `lmodern` package::\n\n    --stylesheet=lmodern\n\nExample 2:\n  Use the `preamble.tex` home-made custom style sheet together with\n  the package `kerkis` (Bookman fonts)::\n\n    --stylesheet=kerkis,preamble.tex\n\nExample 3:\n  Select Palatino fonts with old-style numbers and true small-caps\n  with the LaTeX command ::\n\n    \\usepackage[osf,sc]{mathpazo}\n\n  in the `LaTeX preamble`_ or `custom style sheets`_.\n\nStylesheet Repository\n  There is a `repository of user-contributed style sheets`_ in the\n  Docutils Sandbox_.\n\n.. _clsguide: https://mirrors.ctan.org/macros/latex/base/clsguide.pdf\n.. _stylesheet: config.html#stylesheet-latex-writers\n.. _embed-stylesheet: config.html#embed-stylesheet-latex-writers\n.. _repository of user-contributed style sheets:\n   ../../../sandbox/stylesheets/\n.. _sandbox: ../../../sandbox/\n\n\nLaTeX preamble\n``````````````\n\nConfiguration by LaTeX code in the document preamble is also possible\nwithout a separate stylesheet. This way, packages can be loaded with\noptions or commands re-defined without the need to create a separate\nfile (new in Docutils 0.7).\n\nOption:\n  latex-preamble_\n\nDefault:\n  used for `font setup`_\n\nExample:\n  To use the better looking ``txtt`` font for monospaced text define the\n  latex-preamble_ setting in a configuration file::\n\n     latex-preamble: \\renewcommand{\\ttdefault}{txtt}\n                     \\usepackage{mathptmx}          % Times\n                     \\usepackage[scaled=.92]{helvet}  % Helvetica\n\n.. _latex-preamble: config.html#latex-preamble\n.. _PDF standard fonts: https://en.wikipedia.org/wiki/PDF#Standard_Type_1_Fonts\n.. _Linux Libertine: http://www.linuxlibertine.org\n\n\nTemplates\n`````````\n\nSome customizations require commands at places other than the insertion\npoint of stylesheets or depend on the deletion/replacement of parts of the\ndocument. This can be done via a custom template. See the `publisher\ndocumentation`_ for a description of the document parts available in a\ntemplate file.\n\nOption:\n  template_\n\nIn addition to the 'default.tex' template, the latex writer directory\ncontains the alternatives 'titlepage.tex' (separate title page) and\n'titlingpage.tex'\" (separate title page with the `memoir`_\n`document class`_).\n\nExample:\n  Print a title page including docinfo, dedication, and abstract::\n\n    --template=titlepage.tex\n\n.. _publisher documentation: ../api/publisher.html\n.. _template: config.html#template-latex-writers\n\nRaw LaTeX\n`````````\n\nBy means of the `raw directive`_ or a derived `custom role`_, one can\ngive commands directly to LaTeX. These can be both, styling as well as\nprinting commands.\n\nExample:\n  Math formula::\n\n    .. raw:: latex\n\n       \\[x^3 + 3x^2a + 3xa^2 + a^3,\\]\n\n  (Drawback: the formula will be invisible in other output formats. Better\n  use the `math directive`_)\n\nMost LaTeX code examples also work as raw LaTeX inside the document.\nAn exception are commands that need to be given in the document\npreamble (e.g. package loading with ``\\usepackage``, which can be\nachieved with the ``--style-sheet`` or ``--latex-preamble`` command\nline options instead). Remember to use *re-defining* commands for\ncustomizing `Docutils specific LaTeX macros`_ with raw LaTeX.\n\nExample:\n  Define the transition command as page break::\n\n    .. raw:: latex\n\n      \\renewcommand*{\\DUtransition}{\\pagebreak[4]}\n\nSee also:\n  * Defining a macro for a `custom role`_.\n  * Forcing `page breaks`_.\n\n.. _raw directive: ../ref/rst/directives.html#raw\n.. _math directive: ../ref/rst/directives.html#math\n\n\nHow to configure the ...\n========================\n\nadmonitions\n-----------\n\nAdmonitions__ are specially marked \"topics\" that can appear anywhere an\nordinary body element can.\n\n__ ../ref/rst/directives.html#admonitions\n\nEnvironment:\n  ``DUadmonition``\n\n  (Command ``\\DUadmonition`` with legacy-class-functions_.)\n\nDefault:\n  Typeset in a frame (90 % of text width).\n\nThe admonition title is typeset with the ``\\DUtitle`` command (see `titles`_).\n\nExample 1:\n  A lighter layout without the frame::\n\n    \\newenvironment{DUadmonition}%\n      {\\begin{quote}}\n      {\\end{quote}}\n\nExample 2:\n  Print all admonitions in the margin::\n\n    \\usepackage{environ}\n    \\NewEnviron{DUadmonition}{\\marginpar{\\BODY}}\n\nExample 3:\n  Use the ``.. note::`` admonition for a margin note::\n\n    \\usepackage{environ}\n    \\newcommand{\\DUCLASSnote}{%\n      \\RenewEnviron{DUadmonition}{\\marginpar{\\BODY}}%\n      \\renewcommand{\\DUtitle}[1]{}% suppress title (\"Note\")\n    }\n\n.. caution:: Make sure there is enough space in the margin.\n   ``\\marginpar`` fails in some places or with some content. See also the\n   environ_ and marginnote_ packages.\n\n.. _environ: https://ctan.org/pkg/environ\n.. _marginnote: https://ctan.org/pkg/marginnote\n\n\n.. _custom role:\n\ncustom interpreted text roles\n-----------------------------\n\nThe rst `role directive`_ allows defining custom `text roles`_ that mark\nparts of inline text (spans) with class arguments (see section classes_).\n\nCommands:\n  ``\\DUrole``: dispatcher command\n\n  ``\\DUrole«classargument»``: optional styling command with 1 argument (the\n  role content).\n\nDefault:\n  The default definition of ``\\DUrole{«classargument»}{}`` calls the macro\n  named ``\\DUrole«classargument»{}`` if it is defined and silently ignores\n  this class argument if not.\n\nExample 1:\n  Typeset text in small caps::\n\n    .. role:: smallcaps\n\n    :smallcaps:`Fourier` transformation\n\n  This is transformed to the LaTeX code::\n\n    \\DUrole{smallcaps}{Fourier} transformation\n\n  The definition ::\n\n    \\newcommand{\\DUrolesmallcaps}{\\textsc}\n\n  as `raw LaTeX`_ or in the custom `style sheet`_ will give the expected\n  result (if the text font_ supports small caps).\n\nExample 2:\n  Subscript text in normal size and *italic* shape::\n\n  .. role:: sub(subscript)\n\n  As \"sub\" inherits from the standard \"subscript\" role, the LaTeX macro\n  only needs to set the size and shape::\n\n    \\newcommand{\\DUrolesub}{\\normalsize\\itshape}\n\nExample 3:\n  A role with several classes and a converted class name::\n\n    .. role:: custom4\n       :class: argI argII arg_3\n\n  is translated to the nested commands::\n\n    \\DUrole{argi}{\\DUrole{argii}{\\DUrole{arg-3}{<content>}}}\n\n  With the definitions::\n\n    \\newcommand{\\DUroleargi}[1]{\\textsc}\n    \\newcommand{\\DUroleargii}[1]{{\\large #1}}\n    \\makeatletter\n    \\@namedef{DUrolearg-3}{\\textbf}\n    \\makeatother\n\n  in a `style sheet`_\\ [#]_ or as `raw LaTeX`_ in the document source,\n  text styled with ``:custom4:`large bold small-caps``` will be typeset\n  accordingly.\n\n..

(For details see, e.g., the testflow_ package\n     documentation.)\n\n\n  Example 3:\n    Use the teletype font from the txfonts_ package.

[LMHT] `Linux Man Page Howto <https://tldp.org/HOWTO/Man-Page/>`__.\n\nConventions\n'''''''''''\n\n* man pages have a special structure and organization. From the manpage\n  to *man*::\n\n    The table below shows the section numbers of the manual followed  by  the\n    types of pages they contain.\n\n    1   Executable programs or shell commands\n    2   System calls (functions provided by the kernel)\n    3   Library calls (functions within program libraries)\n    4   Special files (usually found in /dev)\n    5   File formats and conventions eg /etc/passwd\n    6   Games\n    7   Miscellaneous  (including  macro  packages and conven-\n        tions), e.g. man(7), groff(7)\n    8   System administration commands (usually only for root)\n    9   Kernel routines [Non standard]\n\n    A manual page consists of several parts.\n\n    They  may  be  labelled  NAME,  SYNOPSIS,  DESCRIPTION,  OPTIONS,  FILES,\n    SEE ALSO, BUGS, and AUTHOR.\n\n    The  following  conventions apply to the SYNOPSIS section and can be used\n    as a guide in other sections.\n\n    bold text          type exactly as shown.\n    italic text        replace with appropriate argument.\n    [-abc]             any or all arguments within [ ] are optional.\n    -a|-b              options delimited by | cannot be used together.\n    argument ...       argument is repeatable.\n    [expression] ...   entire expression within [ ] is repeatable.\n\n    The command or function illustration is a pattern that should  match  all\n    possible  invocations.   In some cases it is advisable to illustrate sev-\n    eral exclusive invocations as is shown in the SYNOPSIS  section  of  this\n    manual page.\n\n* new lines in general.\n\n  Consecutive blank lines are merged by the viewer but not on printouts.\n  So one has to be cautious. This is most disturbing when printing\n  postscript.\n\n  .. NOTE::\n\n    1. Roff requests only work when at line start.\n    2. But consecutive blank lines are merged by the viewer but not on\n       printouts.\n\n    So try the rule start new lines in ``visit_``-functions, but only if\n    necessary. E.g. ``field-names`` are already on a new line because of\n    docutils structure.\n\n* Indentation, left margin:\n\n  - The writer includes two macros ``.INDENT`` and ``.UNINDENT`` that\n    keep track of the indentation in roff-code, for line-blocks python\n    keeps track of it. WHAT should be the preferred way ?\n\n    But standard macros like ``.PP`` might reset it.\n\n  - Why do ``.RE`` and ``.RS`` not work?\n\n  .. Note::\n     Current indent is in register ``.i``.\n\n* [LMHT]_ Filenames are always in italics, except in the SYNOPSIS section,\n  use::\n\n    .I /usr/include/stdio.h\n\n  and::\n\n    .B #include <stdio.h>\n\n* Tables are possible, via the external processor tbl, although one should\n  avoid them.\n\nTODO - Open issues\n''''''''''''''''''\n\n* How to escape double quotes in macro arguments ?\n* Typeset URLs : ``man 7 man`` on linux says use ``.UR`` and ``.UE``.\n* How to typeset command/manpage names in text.\n* How to write long syntax lines.\n* Line ends around email or web addresses in texts.\n  How to distinguish something is inline or not ?\n\n* Images and equations are discouraged.\n* Lists in admonitions are not intended.\n* Encoding declaration ``'\\\" t -*- coding: ISO-8859-1 -*-``\n  in first line.\n\n  BUT if UTF-8 is declared tables are no longer processed.\n\n* Input and output encoding are problematic at least.\n\n.. _Docutils: https://docutils.sourceforge.io/\n"

    "content": "=======================\nOdt Writer for Docutils\n=======================\n\n:Author: Dave Kuhlman\n:Contact: docutils-develop@lists.sourceforge.net\n:Revision: $Revision$\n:Date: $Date$\n:Copyright: This document has been placed in the public domain.\n\n:abstract: This document describes the Docutils odtwriter\n    (rst2odt.py).\n\n.. sectnum::\n\n.. contents::\n\n\nIntroduction\n============\n\nWhat it does -- ``rst2odt.py`` translates reST\n(reStructuredText) into a Open Document Format ``.odt`` file.  You\ncan learn more about the ODF format here:\n\n- `OASIS Open Document Format for Office Applications\n  (OpenDocument) TC`_\n\n- `Open Document at Wikipedia`_\n\nYou should be able to open documents (.odt files) generated with\n``rst2odt.py`` in ``OpenOffice/oowriter``.\n\nYou can learn more about Docutils and reST here: `Docutils`_\n\n\nRequirements\n============\n\nIn addition to the Docutils standard requirements, ``odtwriter``\nrequires:\n\n- Optional -- `Pygments`_ is required if you want syntax\n  highlighting of code in literal blocks.  See section `Syntax\n  highlighting`_.\n\n- Optional -- `Python Imaging Library`_ (PIL) is required if on an\n  image or figure directive, you specify ``scale`` but not ``width``\n  and ``height``.  See section `Images and figures`_.\n\n\n\nHow to Use It\n=============\n\nRun it from the command line as follows::\n\n    $ rst2odt.py myinput.txt myoutput.odt\n\nTo see usage information and to learn about command line options\nthat you can use, run the following::\n\n    $ rst2odt.py --help\n\nExamples::\n\n    $ rst2odt.py -s -g python_comments.txt python_comments.odt\n\n    $ rst2odt.py --source-url=odtwriter.txt --generator \\\n        --stylesheet=/myconfigs/styles.odt odtwriter.txt odtwriter.odt\n\n\nConfiguration file\n------------------\n\nThe options described below can also be set in a configuration file.\nUse section ``[odf_odt writer]`` to set options specific to the\n``odtwriter``.  For example::\n\n    [odf_odt writer]\n    stylesheet: styles1.odt\n\nSee the \"Docutils Configuration\" document for more information on\nDocutils configuration files, including locations which are\nsearched.\n\n\nCommand line options\n--------------------\n\nThe following command line options are specific to ``odtwriter``:\n\n--stylesheet=<URL>      Specify a stylesheet URL, used verbatim.\n                        Default: writers/odf_odt/styles.odt in the\n                        installation directory.\n--odf-config-file=<file>\n                        Specify a configuration/mapping file relative to the\n                        current working directory for additional ODF options.\n                        In particular, this file may contain a section named\n                        \"Formats\" that maps default style names to names to be\n                        used in the resulting output file allowing for\n                        adhering to external standards. For more info and the\n                        format of the configuration/mapping file, see the\n                        odtwriter doc.\n--cloak-email-addresses\n                        Obfuscate email addresses to confuse harvesters while\n                        still keeping email links usable with standards-\n                        compliant browsers.\n--no-cloak-email-addresses\n                        Do not obfuscate email addresses.\n--table-border-thickness=TABLE_BORDER_THICKNESS\n                        Specify the thickness of table borders in thousands of\n                        a cm.  Default is 35.\n--add-syntax-highlighting\n                        Add syntax highlighting in literal code blocks.\n--no-syntax-highlighting\n                        Do not add syntax highlighting in literal code blocks.\n                        (default)\n--create-sections       Create sections for headers.  (default)\n--no-sections           Do not create sections for headers.\n--create-links          Create links.\n--no-links              Do not create links.

(default)\n--generate-list-toc     Generate a bullet list table of contents, not an\n                        ODF/``oowriter`` table of contents.\n--generate-oowriter-toc\n                        Generate an ODF/``oowriter`` table of contents,\n                        not a bullet list.  (default) **Note:**\n                        ``odtwriter`` is not able to determine page\n                        numbers, so you will need to open the\n                        generated document in ``oowriter``, then\n                        right-click on the table of contents and\n                        select \"Update\" to insert page numbers.\n--custom-odt-header=CUSTOM_HEADER\n                        Specify the contents of an custom header line.  See\n                        odf_odt writer documentation for details about special\n                        field character sequences.  See section\n                        `Custom header/footers: inserting page numbers, date, time, etc`_\n                        for details\n--custom-odt-footer=CUSTOM_FOOTER\n                        Specify the contents of an custom footer line.  See\n                        odf_odt writer documentation for details about special\n                        field character sequences.  See section\n                        `Custom header/footers: inserting page numbers, date, time, etc`_\n                        for details\n\n\n\nStyles and Classes\n==================\n\n``odtwriter`` uses a number of styles that are defined in\n``styles.xml`` in the default ``styles.odt``.  This section\ndescribes those styles.\n\nNote that with the ``--stylesheet`` command line option, you can\nuse either ``styles.odt`` or ``styles.xml``, as described below.\nUse of ``styles.odt`` is recommended over ``styles.xml``.\n\nYou can modify the look of documents generated by ``odtwriter`` in\nseveral ways:\n\n- Open (a copy of) ``styles.odt`` in ``OpenOffice/oowriter`` and\n  modify the style you wish to change. Now, save this document,\n  then generate your documents using this modified copy of\n  ``styles.odt``.\n\n  In my version of ``oowriter``, to modify styles, either (1)\n  press F11 or (2) use menu item \"Format/Styles and Formatting\",\n  then right-click on the relevant style and select \"Modify\".\n  Modify the style, then save your document.\n\n- Open a document generated by ``odtwriter`` in `oowriter``.  Now,\n  edit the style you are interested in modifying.  Now, you\n  can extract the styles.xml file from your document and either\n  (1) use this as your default styles file or (2) copy and paste\n  the relevant style definition into your styles.xml.\n\n- Extract ``styles.xml`` from ``styles.odt`` using your favorite\n  ``zip/unzip`` tool.  Then modify ``styles.xml`` with a text\n  editor.  Now re-zip it back into your own ``styles.odt``, or use\n  it directly by specifying it with the ``--stylesheet`` command\n  line option.  **Hint:** If you intend to extract ``styles.xml``\n  from an ``.odt`` file (and then \"re-zip\" it), you should turn off\n  XML optimization/compression in ``oowriter``.  In order to this\n  in ``oowriter``, use Tools --> Options...  --> Load-Save -->\n  General and turn off \"Size optimization for XML format\".\n\n- Open an empty (or new) document in ``oowriter``.  Define all of\n  the styles described in this section.  Then, use that document (a\n  .odt file) as your stylesheet.  ``odtwriter`` will extract the\n  ``styles.xml`` file from that document and insert it into the\n  output document.\n\n- Some combination of the above.\n\n\nStyles used by odtwriter\n------------------------\n\nThis section describes the styles used by ``odtwriter``.\n\nNote that we do not describe the \"look\" of these styles.  That can\nbe easily changed by using ``oowriter`` to edit the document\n``styles.odt`` (or a copy of it), and modifying any of the styles\ndescribed here.\n\nTo change the definition and appearance of these styles, open\n``styles.odt`` in ``oowriter`` and open the Styles and Formatting\nwindow by using the following menu item::\n\n    Format --> Styles and Formatting\n\nThen, click on the Paragraph Styles button or the Character Styles\nbutton at the top of the Styles and Formatting window.  You may\nalso need to select \"All Styles\" from the drop-down selection list\nat the bottom of the Styles and Formatting window in order to see\nthe styles used by ``odtwriter``.\n\nNotice that you can make a copy of file ``styles.odt``, modify it\nusing ``oowriter``, and then use your copy with the\n``--stylesheet=<file>`` command line option.  Example::\n\n    $ rst2odt.py --stylesheet=mystyles.odt test2.txt test2.odt\n\n\nParagraph styles\n~~~~~~~~~~~~~~~~\n\nrststyle-attribution\n    The style for attributions, for example, the attribution in a\n    ``.. epigraph::`` directive.

Here is an example which which attaches\nthe ``rststyle-heading1`` style to the generated rubric::\n\n    .. rubric:: This is my first rubric\n       :class: rststyle-heading1\n\n\nTable styles\n~~~~~~~~~~~~\n\nA table style is generated by ``oowriter`` for each table that you\ncreate.  Therefore, ``odtwriter`` attempts to do something similar.\nThese styles are created in the ``content.xml`` document in the\ngenerated ``.odt`` file.  These styles have names prefixed with\n\"rststyle-table-\".\n\nThere are two ways in which you can control the styles of your\ntables: one simple, the other a bit more complex, but more\npowerful.\n\nFirst, you can change the thickness of the borders of all tables\ngenerated in a document using the \"--table-border-thickness\"\ncommand line option.\n\nSecond, you can control additional table properties and you can\napply different styles to different tables within the same document\nby customizing and using tables in your stylesheet: ``styles.odt``\nor whatever you name your copy of it using the --stylesheet command\nline option.  Then, follow these rules to apply a table style to\nthe tables in your document:\n\n- The default table style -- Optionally, alter and customize the\n  style applied by default to tables in your document by modifying\n  table \"rststyle-table-0\" in your stylesheet (``styles.odt`` or a\n  copy).  Caution: Do not change the name of this table.\n\n- User-created table styles -- Add one or more new table styles to\n  be applied selectively to tables in your document by doing the\n  following:\n\n  1. Using ``oowriter``, add a table to your stylesheet and give it\n     a name that starts with the prefix \"rststyle-table-\", for\n     example \"rststyle-table-vegetabledata\".  Customize the table's\n     border thickness, border color, and table background color.\n\n  2. In your reStructuredText document, apply your new table style\n     to a specific table by placing the \"..  class::\" directive\n     immediately before the table, for example::\n\n         .. class:: rststyle-table-vegetabledata\n\nThe default table style will be applied to all tables for which you\ndo not specify a style with the \"..  class::\" directive.\n\nCustomize the table properties in ``oowriter`` using the table\nproperties dialog for the table (style) that you wish to customize.\n\nNote that \"--table-border-thickness\" command line option overrides\nthe border thickness specified in the stylesheet.\n\nThe specific properties that you can control with this second\nmethod are the following:\n\n- Border thickness and border color.\n\n- Background color -- When you change the background color of a\n  table to be used as a style (in ``styles.odt`` or whatever you\n  name it), make sure you change the background color for the\n  *table* and *not* for a cell in the table.  ``odtwriter`` picks\n  the background color from the table, not from a cell within the\n  table.\n\n\nLine block styles\n~~~~~~~~~~~~~~~~~~\n\nThe line block styles wrap the various nested levels of line\nblocks.  There is one line block style for each indent level.\n\nrststyle-lineblock1\n    Line block style for line block with no indent.\n\nrststyle-lineblock2\n    Line block style for line block indented 1 level.\n\nrststyle-lineblock3\n    Line block style for line block indented 2 levels.\n\nrststyle-lineblock4\n    Line block style for line block indented 3 levels.\n\nrststyle-lineblock5\n    Line block style for line block indented 4 levels.\n\nrststyle-lineblock6\n    Line block style for line block indented 5 levels.\n\nNotes:\n\n- ``odtwriter`` does not check for a maximum level of indents\n  within line blocks.  Therefore, you can define additional line\n  block styles for additional levels if you need them.  Define\n  these styles with the names ``rststyle-lineblock7``,\n  ``rststyle-lineblock8``, ...\n\n- Since the line block style is used to create indentation, a line\n  block that is inside a block quote will use\n  ``rststyle-lineblock2`` as its first level of indentation.\n\n\nFootnote and citation styles\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nrststyle-footnote\n    The style for footnotes.  This style affects the footnote\n    content, *not* the footnote reference in the body of the document.\n\nrststyle-citation\n    The style for citations.  This style affects the citation\n    content, *not* the citation reference in the body of the document.\n    You might need to adjust the indentation in this style\n    depending on the length of the label used in your citations.\n\n\nHeading and title styles\n~~~~~~~~~~~~~~~~~~~~~~~~~\n\nrststyle-heading{1|2|3|4|5}\n    The styles for headings (section titles and sub-titles).  Five\n    levels of sub-headings are provided: rststyle-heading1 through\n    rststyle-heading5.\n\nrststyle-title\n    The style for the document title.\n\nrststyle-subtitle\n    The style for the document sub-title.\n\n\nImage and figure styles\n~~~~~~~~~~~~~~~~~~~~~~~~~\n\nrststyle-image\n    The style applied to an image, either an image by itself or an\n    image in a figure.\n\nrststyle-figureframe\n    The style applied to a figure (actually to the frame that\n    surrounds a figure).\n\n\n\nDefining and using a custom stylesheet\n---------------------------------------\n\nYou can create your own custom stylesheet.  Here is how:\n\n1. Make a copy of ``styles.odt``, which is in the distribution.\n\n2. Open your copy of ``styles.odt`` in ``oowriter``.  Modify styles\n   in that document.  Then, save it.\n\n3. When you run ``rst2odt.py``, use the ``--stylesheet`` command\n   line option to use your custom stylesheet.  Run ``rst2odt.py\n   --help`` to learn more about these options.\n\n\nWhy custom stylesheets\n~~~~~~~~~~~~~~~~~~~~~~~\n\nHere are a few reasons and ideas:\n\n- The page size is stored in the style sheet.  The default page\n  size is ``Letter``.  You can change the page size (for example,\n  to ``A4``) in your custom stylesheet by opening it in\n  ``oowriter``, then clicking on menu: ``Format/Page...``, then\n  clicking on the ``Page`` tab.\n\n\n\nDefining and using custom style names\n-------------------------------------\n\n[Credits: Stefan Merten designed and implemented the custom style names\ncapability.  Thank you, Stefan.]\n\nYou can also instruct ``odtwriter`` to use style names of your own\nchoice.\n\n\nWhy custom style names\n~~~~~~~~~~~~~~~~~~~~~~\n\nHere are a few reasons and ideas:\n\n- Suppose that your organization has a standard set of styles in\n  OOo ``oowriter`` and suppose that the use of these styles is\n  required. You would like to generate ODF documents from\n  reST text files, and you want the generated documents to contain\n  these styles.\n\n- Suppose that your company or organization has a policy of using a\n  certain MS Word template for some set of documents.  You would\n  like to generate ODF documents that use these custom style names,\n  so that you can export these documents from ODF ``oowriter`` to MS\n  Word documents that use these style names.\n\n- Suppose that your documents are written in a language other than\n  English.  You would like the style names visible in the \"Styles\n  and Formatting\" window in OOo ``oowriter`` (menu item\n  ``Format/Styles and Formatting``) to be understandable in the\n  language of your users.\n\n- ``odtwriter`` maps single asterisks/stars (for example, \\*stuff\\*)\n  to emphasis and double stars to strong.  You'd like to reverse\n  these.  Or, you would like to generate headings level 3 and 4\n  where headings level 1 and 2 would normally be produced.\n\n\nHow to use custom style names\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nIn order to define custom style names and to generate documents that\ncontain them, do the following:\n\n\n1. Create a configuration file containing a \"Formats\" section.  The\n   configuration file obeys the file format supported by the Python\n   ConfigParser module:\n   `ConfigParser -- Configuration file parser --\n   https://docs.python.org/3/library/configparser.html\n   <https://docs.python.org/3/library/configparser.html>`_.\n\n2. In the \"Formats\" section of the configuration file, create one\n   option (a name-value pair) for each custom style name that you\n   wish to define.  The option name is the standard ``odtwriter``\n   style name (without \"rststyle-\"), and the value is your custom\n   style name.  Here is an example::\n\n       [Formats]\n       textbody: mytextbody\n       bulletitem: mybulletitem\n       heading1: myheading1\n           o\n           o\n           o\n\n3. Create a styles document that defines the styles generated by\n   ``odtwriter``.  You can create and edit the styles in OOo\n   ``oowriter``.  It may be helpful to begin by making a copy of the\n   styles document that is part of the ``odtwriter`` distribution\n   (``styles.odt``).\n\n4. When you run ``odtwriter``, specify the ``--odf-config-file``\n   option.  You might also want to specify your styles document\n   using the ``--stylesheet`` option in order to include your\n   custom style definitions.  For example::\n\n       rst2odt.py --odf-config-file=mymappingfile.ini \\\n         --stylesheet=mystyles.odt mydoc.txt mydoc.odt\n\n\nClasses\n-------\n\n``odtwriter`` uses the following Docutils class to provide additional\ncontrol of the generation of ODF content:\n\n- Class ``wrap`` -- Use this to cause the wrapping of text around\n  an image.  The default is *not* to wrap text around images.\n  Here is an example::\n\n      .. class:: wrap\n      .. image:: images/flower01.png\n          :alt: A bright yellow flower\n          :height: 55\n          :width: 60\n\n\nRoles\n-------\n\nYou can use a Docutils custom interpreted text role to attach a\ncharacter style to an inline area of text.  This capability also\nenables you to attach a new character style (with a new name) that\nyou define yourself.  Do this by defining your role in a stylesheet\nas a character style with \"rststyle-\" prefixed to your role name,\nthen use the ``role`` directive and inline markup to apply your\nrole.\n\nIn order to use this capability, do the following:\n\n- Define the character style for your custom role in a stylesheet\n  (a copy of ``styles.odt``) with the prefix \"rststyle-\".\n  Remember: (1) If the name of your custom role is \"pretty\", then\n  define a character style named \"rststyle-pretty\".  (2) Define the\n  style as a *character* style, and *not*, for example as a\n  paragraph style.\n\n- Declare your role in the source reStructuredText document in a\n  ``role`` directive.  Example::\n\n      .. role:: pretty\n\n- Use inline markup to apply your role to text.  Example::\n\n      We have :pretty:`very nice` apples.\n\nHere is another example::\n\n    .. role:: fancy\n\n    Here is some :fancy:`pretty text` that looks fancy.\n\nFor more on roles see:\n`Custom Interpreted Text Roles --\nhttps://docutils.sourceforge.io/docs/ref/rst/directives.html#custom-interpreted-text-roles\n<https://docutils.sourceforge.io/docs/ref/rst/directives.html#custom-interpreted-text-roles>`_.\n\n**Note:** The ability to base a role on another existing role is\n*not* supported by ``odtwriter``.\n\n\nHints and Suggestions and Features\n==================================\n\nTable of contents\n-----------------\n\nThe ``..contents::`` directive causes ``odtwriter`` to generate\neither:\n\n1. A static, outline style table of contents, if the\n   ``--generate-list-toc`` command line option is specified, or\n\n2. An ODF/``oowriter`` style table of contents containing\n   dynamically updated page numbers and with the formatting control\n   that ``oowriter`` gives you.  This is the default, or use the\n   command line option ``--generate-list-toc``.  **Note:**\n   ``odtwriter`` is not able to determine page numbers, so you will\n   need to open the generated document in ``oowriter``, then\n   right-click on the table of contents and select \"Update\" to\n   insert correct page numbers.\n\n\nSyntax highlighting\n-------------------\n\n``odtwriter`` can add syntax highlighting to code in code\nblocks.  In order to activate this, do all of the following:\n\n1. Install `Pygments`_ and ...\n\n2. Use the command line option ``--add-syntax-highlighting``.\n   Example::\n\n       $ rst2odt.py --add-syntax-highlight test.txt test.odt\n\nThe following styles are defined in styles.odt and are used for\nliteral code blocks and syntax highlighting:\n\n- Paragraph styles:\n\n  - rststyle-codeblock -- The style for the code block as a whole.\n\n- Character styles:\n\n  - rststyle-codeblock-classname -- class names.\n\n  - rststyle-codeblock-comment -- comments.\n\n  - rststyle-codeblock-functionname -- function names.\n\n  - rststyle-codeblock-keyword -- Python language keywords.\n\n  - rststyle-codeblock-name -- other names, for example,\n    variables.\n\n  - rststyle-codeblock-number -- literal numbers, including\n    integers, floats, hex numbers, and octal numbers.\n\n  - rststyle-codeblock-operator -- Python operators.\n\n  - rststyle-codeblock-string -- literal strings.\n\nEach of the above styles has a default appearance that is defined\nin ``styles.odt``.  To change that definition and appearance, open\n``styles.odt`` in ``oowriter`` and use menu item::\n\n    Format --> Styles and Formatting\n\nThen, click on the Paragraph Styles button or the Character Styles\nbutton at the top of the Styles and Formatting window.  You may\nalso need to select \"All Styles\" from the drop-down selection list\nat the bottom of the Styles and Formatting window.\n\n\n\nThe container directive\n-----------------------\n\nThere is limited support for the ``container`` directive.  The\nlimitations and rules for the container directive are the following:\n\n- Only the first class in the list of classes (arguments) is used.\n\n- That class/style must be a paragraph style and not (for example) a\n  character style.\n\n- The style/class given to the container directive will have a\n  \"rststyle-\" prefix in the odt file.\n\nSo, for example::\n\n    .. container:: style-1 style-2 style-3\n\n        a block of text\n\n- Only ``style-1`` is used; ``style-2`` and ``style-3`` are ignored.\n\n- ``rststyle-style-1`` must be defined.  It should be an existing,\n  predefined style, or you should define it in your stylesheet\n  (``styles.odt`` or the argument to the ``--stylesheet`` command\n  line option).\n\n- ``rststyle-style-1`` must be a paragraph style.\n\nTo define a paragraph style, use the following menu item in\n``oowriter``::\n\n    Format --> Styles and Formatting\n\nThen, click on the Paragraph Styles button.\n\nThe following example attaches the ``rststyle-heading2`` style (a\npredefined style) to each paragraph/line in the container::\n\n    .. container:: heading2\n\n       Line 1 of container.\n\n       Line 2 of container.\n\nMore information on how to define a new style (for example, in your\n``styles.odt``) can be found in section\n`Defining and using custom style names`_.\n\n\n\nThe table directive\n-------------------\n\nThe ``table`` directive can be used to add a title to a table.\nExample::\n\n    .. table:: A little test table\n\n        =========== =============\n        Name        Value\n        =========== =============\n        Dave        Cute\n        Mona        Smart\n        =========== =============\n\nThe above will insert the title \"A little test table\" at the top of the\ntable.  You can modify the appearance of the title by modifying the\nparagraph style ``rststyle-table-title``.\n\n\nFootnotes and citations\n-----------------------\n\nFootnotes and citations are supported.\n\nThere are additional styles ``rststyle-footnote`` and\n``rststyle-citation`` for footnotes and citations. See\n`Footnote and citation styles`_.\n\nYou may need to modify the citation style to fit the length of your\ncitation references.\n\nEndnotes -- There are command line options that control whether\n``odtwriter`` creates endnotes instead of footnotes.  Endnotes\nappear at the end of the document instead of at the bottom of the\npage.  See flags ``--endnotes-end-doc`` and\n``--no-endnotes-end-doc`` in section `Command line options`_.\n\n\nImages and figures\n------------------\n\nIf on the image or the figure directive you provide the scale option\nbut do not provide the width and height options, then ``odtwriter``\nwill attempt to determine the size of the image using the `Python\nImaging Library`_ (PIL).  If ``odtwriter`` cannot find and import\nPython Imaging Library, it will raise an exception.  If this\nocurrs, you can fix it by doing one of the following:\n\n- Install the Python Imaging Library or\n\n- Remove the ``scale`` option or\n\n- Add both the ``width`` and the ``height`` options.\n\nSo, the rule is: if on any image or figure, you specify scale but\nnot both width and height, you must install the `Python Imaging\nLibrary`_ library.\n\nFor more information about PIL, see: `Python Imaging Library`_.\n\n\nThe raw directive\n-----------------\n\nThe ``raw`` directive is supported.  Use output format type \"odt\".\n\nYou will need to be careful about the formatting of the raw\ncontent.  In particular, introduced whitespace might be a problem.\n\nIn order to produce content for the raw directive for use by\n``odtwriter``, you might want to extract the file ``content.xml``\nfrom a ``.odt`` file (using some Zip tool), and then clip, paste,\nand modify a selected bit of it.\n\nHere is an example::\n\n    .. raw:: odt\n\n        <text:p text:style-name=\"rststyle-textbody\">Determining\n        <text:span text:style-name=\"rststyle-emphasis\">which</text:span>\n        namespace a name is in is static.  It can be determined by a\n        lexical scan of the code.  If a variable is assigned a value\n        <text:span text:style-name=\"rststyle-emphasis\">anywhere</text:span>\n        in a scope (specifically within a function or method body),\n        then that variable is local to that scope.  If Python does\n        not find a variable in the local scope, then it looks next\n        in the global scope (also sometimes called the module scope)\n        and then in the built-ins scope.  But, the\n        <text:span text:style-name=\"rststyle-inlineliteral\">global</text:span>\n        statement can be used to force Python to find and use a global\n        variable (a variable defined at top level in a module) rather\n        than create a local one.</text:p>\n\n\nThe meta directive\n------------------\n\n``odtwriter`` supports the ``meta`` directive.  \"keywords\"\nand \"description\" are set in their respective odt fields.\nOther meta fields are set as \"Custom Properties\".\nHere is an example::\n\n    .. meta::\n       :keywords: reStructuredText, docutils, formatting\n       :description lang=en: A reST document, contains formatted\n           text in a formatted style.\n       :custom_var: Value\n\nTo see the results of the ``meta`` directive in ``oowriter``,\nselect menu item \"File/Properties...\", then click on the\n\"Description\" tab (\"keywords\" and \"description\" fields) and the\n\"Custom Properties\" tab.\n\n\nFootnote references inside footnotes\n------------------------------------\n\nNot supported.\n\nGet a grip.  Be serious.  Try a dose of reality.\n\n``odtwriter`` ignores them.\n\nThey cause ``oowriter`` to croak.\n\n\nPage size\n---------\n\nThe default page size, in documents generated by ``odtwriter`` is\n``Letter``.  You can change this (for example to ``A4``) by using a\ncustom stylesheet.  See `Defining and using a custom stylesheet`_\nfor instructions on how to do this.\n\nOn machines which support ``paperconf``, ``odtwriter`` can insert\nthe default page size for your locale.  In order for this to work,\nthe following conditions must be met:\n\n1. The program ``paperconf`` must be available on your system.\n   ``odtwriter`` uses ``paperconf -s`` to obtain the paper size.\n   See ``man paperconf`` for more information.\n\n2. The default page height and width must be removed from the\n   ``styles.odt`` used to generate the document.  A Python script\n   ``rst2odt_prepstyles.py`` is distributed with ``odtwriter`` and\n   is installed in the ``bin`` directory.  You can remove the page\n   height and width with something like the following::\n\n       $ rst2odt_prepstyles.py styles.odt\n\n.. warning:: If you edit your stylesheet in ``oowriter`` and then\n    save it, ``oowriter`` automatically inserts a page height and\n    width in the styles for that (stylesheet) document.  If that is\n    not the page size that you want and you want ``odtwriter`` to\n    insert a default page size using ``paperconf``, then you will\n    need to strip the page size from your stylesheet each time you\n    edit that stylesheet with ``oowriter``.\n\n\n\nCustom header/footers: inserting page numbers, date, time, etc\n----------------------------------------------------------------\n\nYou can specify custom headers and footers for your document from\nthe command line.  These headers and footers can be used to insert\nfields such as the page number, page count, date, time, etc.  See\nbelow for a complete list.\n\nTo insert a custom header or footer, use the \"--custom-odt-header\"\nor \"--custom-odt-footer\" command line options.  For example, the\nfollowing inserts a footer containing the page number and page\ncount::\n\n    $ rst2odt.py --custom-odt-footer=\"Page %p% of %P%\" f1.txt f1.odt\n\n\nField specifiers\n~~~~~~~~~~~~~~~~~~\n\nYou can use the following field specifiers to insert ``oowriter``\nfields in your custom headers and footers:\n\n%p%\n    The current page number.\n\n%P%\n    The number of pages in the document.\n\n%d1%\n    The current date in format 12/31/99.\n\n%d2%\n    The current date in format 12/31/1999.\n\n%d3%\n    The current date in format Dec 31, 1999.\n\n%d4%\n    The current date in format December 31, 1999.\n\n%d5%\n    The current date in format 1999-12-31.\n\n%t1%\n    The current time in format 14:22.\n\n%t2%\n    The current time in format 14:22:33.\n\n%t3%\n    The current time in format 02:22 PM.\n\n%t4%\n    The current time in format 02:22:33 PM.\n\n%a%\n    The author of the document (actually the initial creator).\n\n%t%\n    The document title.\n\n%s%\n    The document subject.\n\n\n**Note:** The use of the above field specifiers in the body of your\nreStructuredText document is **not** supported, because these\nspecifiers are not standard across Docutils writers.\n\n\n\nCredits\n=======\n\nStefan Merten designed and implemented the custom style names\ncapability.

Problems are indicated by\n|problematic| text (generated by processing errors; this one is\nintentional).\n\nThe default role for interpreted text is `Title Reference`.  Here are\nsome explicit interpreted text roles: a PEP reference (:PEP:`287`); an\nRFC reference (:RFC:`2822`); a :sub:`subscript`; a :sup:`superscript`;\nand explicit roles for :emphasis:`standard` :strong:`inline`\n:literal:`markup`.\n\n..

These\nare relative links that point to the `Quick reStructuredText`_ user\nreference.  If these links don't work, please refer to the `master\nquick reference`_ document.\n\n__\n.. _Quick reStructuredText: quickref.html\n.. _master quick reference:\n   https://docutils.sourceforge.io/docs/user/rst/quickref.html\n\n.. Note:: This document is an informal introduction to\n   reStructuredText.  The `What Next?`_ section below has links to\n   further resources, including a formal reference.\n\n\nStructure\n---------\n\nFrom the outset, let me say that \"Structured Text\" is probably a bit\nof a misnomer.  It's more like \"Relaxed Text\" that uses certain\nconsistent patterns.  These patterns are interpreted by a HTML\nconverter to produce \"Very Structured Text\" that can be used by a web\nbrowser.\n\nThe most basic pattern recognised is a **paragraph** (quickref__).\nThat's a chunk of text that is separated by blank lines (one is\nenough).  Paragraphs must have the same indentation -- that is, line\nup at their left edge.  Paragraphs that start indented will result in\nindented quote paragraphs. For example::\n\n  This is a paragraph.  It's quite\n  short.\n\n     This paragraph will result in an indented block of\n     text, typically used for quoting other text.\n\n  This is another one.\n\nResults in:\n\n  This is a paragraph.  It's quite\n  short.\n\n     This paragraph will result in an indented block of\n     text, typically used for quoting other text.\n\n  This is another one.\n\n__ quickref.html#paragraphs\n\n\nText styles\n-----------\n\n(quickref__)\n\n__ quickref.html#inline-markup\n\nInside paragraphs and other bodies of text, you may additionally mark\ntext for *italics* with \"``*italics*``\" or **bold** with\n\"``**bold**``\".  This is called \"inline markup\".\n\nIf you want something to appear as a fixed-space literal, use\n\"````double back-quotes````\".  Note that no further fiddling is done\ninside the double back-quotes -- so asterisks \"``*``\" etc. are left\nalone.\n\nIf you find that you want to use one of the \"special\" characters in\ntext, it will generally be OK -- reStructuredText is pretty smart.\nFor example, this lone asterisk * is handled just fine, as is the\nasterisk in this equation: 5*6=30.  If you actually\nwant text \\*surrounded by asterisks* to **not** be italicised, then\nyou need to indicate that the asterisk is not special.  You do this by\nplacing a backslash just before it, like so \"``\\*``\" (quickref__), or\nby enclosing it in double back-quotes (inline literals), like this::\n\n    ``*``\n\n__ quickref.html#escaping\n\n.. Tip:: Think of inline markup as a form of (parentheses) and use it\n   the same way: immediately before and after the text being marked\n   up.  Inline markup by itself (surrounded by whitespace) or in the\n   middle of a word won't be recognized.  See the `markup spec`__ for\n   full details.\n\n__ ../../ref/rst/restructuredtext.html#inline-markup\n\n\nLists\n-----\n\nLists of items come in three main flavours: **enumerated**,\n**bulleted** and **definitions**.  In all list cases, you may have as\nmany paragraphs, sublists, etc. as you want, as long as the left-hand\nside of the paragraph or whatever aligns with the first line of text\nin the list item.\n\nLists must always start a new paragraph -- that is, they must appear\nafter a blank line.\n\n**enumerated** lists (numbers, letters or roman numerals; quickref__)\n  __ quickref.html#enumerated-lists\n\n  Start a line off with a number or letter followed by a period \".\",\n  right bracket \")\" or surrounded by brackets \"( )\" -- whatever you're\n  comfortable with.  All of the following forms are recognised::\n\n    1. numbers\n\n    A. upper-case letters\n       and it goes over many lines\n\n       with two paragraphs and all!\n\n    a. lower-case letters\n\n       3. with a sub-list starting at a different number\n       4. make sure the numbers are in the correct sequence though!\n\n    I. upper-case roman numerals\n\n    i. lower-case roman numerals\n\n    (1) numbers again\n\n    1) and again\n\n  Results in (note: the different enumerated list styles are not\n  always supported by every web browser, so you may not get the full\n  effect here):\n\n  1. numbers\n\n  A. upper-case letters\n     and it goes over many lines\n\n     with two paragraphs and all!\n\n  a. lower-case letters\n\n     3. with a sub-list starting at a different number\n     4. make sure the numbers are in the correct sequence though!\n\n  I. upper-case roman numerals\n\n  i. lower-case roman numerals\n\n  (1) numbers again\n\n  1) and again\n\n**bulleted** lists (quickref__)\n  __ quickref.html#bullet-lists\n\n  Just like enumerated lists, start the line off with a bullet point\n  character - either \"-\", \"+\" or \"*\"::\n\n    * a bullet point using \"*\"\n\n      - a sub-list using \"-\"\n\n        + yet another sub-list\n\n      - another item\n\n  Results in:\n\n  * a bullet point using \"*\"\n\n    - a sub-list using \"-\"\n\n      + yet another sub-list\n\n    - another item\n\n**definition** lists (quickref__)\n  __ quickref.html#definition-lists\n\n  Unlike the other two, the definition lists consist of a term, and\n  the definition of that term.  The format of a definition list is::\n\n    what\n      Definition lists associate a term with a definition.\n\n    *how*\n      The term is a one-line phrase, and the definition is one or more\n      paragraphs or body elements, indented relative to the term.\n      Blank lines are not allowed between term and definition.\n\n  Results in:\n\n  what\n    Definition lists associate a term with a definition.\n\n  *how*\n    The term is a one-line phrase, and the definition is one or more\n    paragraphs or body elements, indented relative to the term.\n    Blank lines are not allowed between term and definition.\n\n\nPreformatting (code samples)\n----------------------------\n(quickref__)\n\n__ quickref.html#literal-blocks\n\nTo just include a chunk of preformatted, never-to-be-fiddled-with\ntext, finish the prior paragraph with \"``::``\".  The preformatted\nblock is finished when the text falls back to the same indentation\nlevel as a paragraph prior to the preformatted block.  For example::\n\n  An example::\n\n      Whitespace, newlines, blank lines, and all kinds of markup\n        (like *this* or \\this) is preserved by literal blocks.\n    Lookie here, I've dropped an indentation level\n    (but not far enough)\n\n  no more example\n\nResults in:\n\n  An example::\n\n      Whitespace, newlines, blank lines, and all kinds of markup\n        (like *this* or \\this) is preserved by literal blocks.\n    Lookie here, I've dropped an indentation level\n    (but not far enough)\n\n  no more example\n\nNote that if a paragraph consists only of \"``::``\", then it's removed\nfrom the output::\n\n  ::\n\n      This is preformatted text, and the\n      last \"::\" paragraph is removed\n\nResults in:\n\n::\n\n    This is preformatted text, and the\n    last \"::\" paragraph is removed\n\n\nSections\n--------\n\n(quickref__)\n\n__ quickref.html#section-structure\n\nTo break longer text up into sections, you use **section headers**.\nThese are a single line of text (one or more words) with adornment: an\nunderline alone, or an underline and an overline together, in dashes\n\"``-----``\", equals \"``======``\", tildes \"``~~~~~~``\" or any of the\nnon-alphanumeric characters ``= - ` : ' \" ~ ^ _ * + # < >`` that you\nfeel comfortable with.  An underline-only adornment is distinct from\nan overline-and-underline adornment using the same character.  The\nunderline/overline must be at least as long as the title text.  Be\nconsistent, since all sections marked with the same adornment style\nare deemed to be at the same level::\n\n  Chapter 1 Title\n  ===============\n\n  Section 1.1 Title\n  -----------------\n\n  Subsection 1.1.1 Title\n  ~~~~~~~~~~~~~~~~~~~~~~\n\n  Section 1.2 Title\n  -----------------\n\n  Chapter 2 Title\n  ===============\n\nThis results in the following structure, illustrated by simplified\npseudo-XML::\n\n    <section>\n        <title>\n            Chapter 1 Title\n        <section>\n            <title>\n                Section 1.1 Title\n            <section>\n                <title>\n                    Subsection 1.1.1 Title\n        <section>\n            <title>\n                Section 1.2 Title\n    <section>\n        <title>\n            Chapter 2 Title\n\n(Pseudo-XML uses indentation for nesting and has no end-tags.  It's\nnot possible to show actual processed output, as in the other\nexamples, because sections cannot exist inside block quotes.  For a\nconcrete example, compare the section structure of this document's\nsource text and processed output.)\n\nNote that section headers are available as link targets, just using\ntheir name.  To link to the Lists_ heading, I write \"``Lists_``\".  If\nthe heading has a space in it like `text styles`_, we need to quote\nthe heading \"```text styles`_``\".\n\n\nDocument Title / Subtitle\n`````````````````````````\n\nThe title of the whole document is distinct from section titles and\nmay be formatted somewhat differently (e.g. the HTML writer by default\nshows it as a centered heading).\n\nTo indicate the document title in reStructuredText, use a unique adornment\nstyle at the beginning of the document.  To indicate the document subtitle,\nuse another unique adornment style immediately after the document title.  For\nexample::\n\n    ================\n     Document Title\n    ================\n    ----------\n     Subtitle\n    ----------\n\n    Section Title\n    =============\n\n    ...\n\nNote that \"Document Title\" and \"Section Title\" above both use equals\nsigns, but are distict and unrelated styles.  The text of\noverline-and-underlined titles (but not underlined-only) may be inset\nfor aesthetics.\n\n\nImages\n------\n\n(quickref__)\n\n__ quickref.html#directives\n\nTo include an image in your document, you use the the ``image`` directive__.\nFor example::\n\n  .. image:: images/biohazard.png\n\nresults in:\n\n.. image:: images/biohazard.png\n\nThe ``images/biohazard.png`` part indicates the filename of the image\nyou wish to appear in the document. There's no restriction placed on\nthe image (format, size etc).  If the image is to appear in HTML and\nyou wish to supply additional information, you may::\n\n  .. image:: images/biohazard.png\n     :height: 100\n     :width: 200\n     :scale: 50\n     :alt: alternate text\n\nSee the full `image directive documentation`__ for more info.\n\n__ ../../ref/rst/directives.html\n__ ../../ref/rst/directives.html#images\n\n\nWhat Next?\n----------\n\nThis primer introduces the most common features of reStructuredText,\nbut there are a lot more to explore.  The `Quick reStructuredText`_\nuser reference is a good place to go next.

    "content": "=========================\nSmart Quotes for Docutils\n=========================\n\n:Author: Günter Milde,\n         based on SmartyPants by John Gruber, Brad Choate, and Chad Miller\n:Contact: docutils-develop@lists.sourceforge.net\n:Revision: $Revision$\n:Date: $Date$\n:License: Released under the terms of the `2-Clause BSD license`_\n:Abstract: This document describes the Docutils `smartquotes` module.\n\n.. _2-Clause BSD license: http://opensource.org/licenses/BSD-2-Clause\n\n.. contents::\n\nDescription\n===========\n\nThe `\"smart_quotes\" configuration setting`_ triggers the SmartQuotes\ntransformation on Text nodes that includes the following steps:\n\n- Straight quotes (``\"`` and ``'``) into \"curly\" quote characters\n- dashes (``--`` and ``---``) into en- and em-dash entities\n- three consecutive dots (``...`` or ``. . .``) into an ellipsis entity.\n\nThis means you can write, edit, and save your documents using plain old\nASCII -- straight quotes, plain dashes, and plain dots -- while Docutils\ngenerates documents with typographical quotes, dashes, and ellipses.\n\nAdvantages:\n\n* Typing speed (especially when blind-typing).\n* The possibility to change the quoting style of the\n  complete document with just one configuration option.\n* Typographical quotes with just 7-bit ASCII characters in the source.\n\nHowever, there are `algorithmic shortcomings`_ for 2 reasons:\n\n* Dual use of the \"ASCII-apostrophe\" (') as single quote and apostrophe.\n* Languages that do not use whitespace around words.\n\nSo, please consider also\n`Why You Might Not Want to Use \"Smart\" Quotes in Your Documents`_.\n\n.. _\"smart_quotes\" configuration setting:\n.. _\"smart_quotes\" setting: config.html#smart-quotes\n\n\nEscaping\n========\n\nThe `SmartQuotes` transform does not modify characters in literal text\nsuch as source code, maths, or literal blocks.\n\nIf you need literal straight quotes (or plain hyphens and periods) in normal\ntext, you can `backslash escape`_ the characters to preserve\nASCII-punctuation.\n\n.. class:: booktabs\n\n=========  ========= == ========  ==========\nInput      Output       Input     Output\n=========  ========= == ========  ==========\n``\\\\``     \\\\           ``\\...``  \\...\n``\\\"``     \\\"           ``\\--``   \\--\n``\\'``     \\'           ``\\```    \\`\n=========  ========= == ========  ==========\n\nThis is useful, for example, when you want to use straight quotes as\nfoot and inch marks:\n\n  6\\'2\\\" tall; a 17\\\" monitor.\n\n.. _backslash escape: ../ref/rst/restructuredtext.html#escaping-mechanism\n\n\nLocalization\n============\n\nQuotation marks have a `variety of forms`__ in different languages and\nmedia.\n\n__ https://en.wikipedia.org/wiki/Quotation_mark#Summary_table\n\n`SmartQuotes` inserts quotation marks depending on the language of the\ncurrent block element and the value of the

Many design and typography nerds, however, break\nout in a nasty rash when they encounter, say, a restaurant sign that uses\na straight apostrophe to spell \"Joe's\".\n\nIf you're the sort of person who just doesn't care, you might well want to\ncontinue not caring. Using straight quotes -- and sticking to the 7-bit\nASCII character set in general -- is certainly a simpler way to live.\n\nEven if you *do* care about accurate typography, you still might want to\nthink twice before \"auto-educating\" the quote characters in your documents.\nAs there is always a chance that the algorithm gets it wrong, you may\ninstead prefer to use the compose key or some other means to insert the\ncorrect Unicode characters into the source.\n\n\nAlgorithmic Shortcomings\n------------------------\n\nThe ASCII character (u0027 APOSTROPHE) is used for apostrophe and single\nquotes. If used inside a word, it is converted into an apostrophe:\n\n   .. class:: language-fr\n\n   Il dit : \"C'est 'super' !\"\n\nAt the beginning or end of a word, it cannot be distinguished from a single\nquote by the algorithm.\n\nThe `right single quotation mark`_ character -- used to close a secondary\n(inner) quote in English -- is also \"the preferred character to use for\napostrophe\" (Unicode_). Therefore, \"educating\" works as expected for\napostrophes at the end of a word, e.g.,\n\n  Mr. Hastings' pen; three days' leave; my two cents' worth.\n\nHowever, when apostrophes are used at the start of leading contractions,\n\"educating\" will turn the apostrophe into an *opening* secondary quote. In\nEnglish, this is *not* the apostrophe character, e.g., ``'Twas brillig``\nis \"miseducated\" to\n\n  'Twas brillig.\n\nIn other locales (French, Italian, German, ...), secondary closing quotes\ndiffer from the apostrophe. A text like::\n\n   .. class:: language-de-CH\n\n   \"Er sagt: 'Ich fass' es nicht.'\"\n\nbecomes\n\n   «Er sagt: ‹Ich fass› es nicht.›»\n\nwith a single closing guillemet in place of the apostrophe.\n\nIn such cases, it's best to use the recommended apostrophe character (’) in\nthe source:\n\n   | ’Twas brillig, and the slithy toves\n   | Did gyre and gimble in the wabe;\n   | All mimsy were the borogoves,\n   | And the mome raths outgrabe.\n\n.. _right single quotation mark:\n    http://www.fileformat.info/info/unicode/char/2019/index.htm\n.. _Unicode: https://www.unicode.org/charts/PDF/U2000.pdf\n\nHistory\n=======\n\nThe smartquotes module is an adaption of \"SmartyPants_\" to Docutils.\n\n`John Gruber`_ did all of the hard work of writing this software in Perl for\n`Movable Type`_ and almost all of this useful documentation.  `Chad Miller`_\nported it to Python to use with Pyblosxom_.\n\nPortions of the SmartyPants original work are based on Brad Choate's nifty\nMTRegex plug-in.  `Brad Choate`_ also contributed a few bits of source code to\nthis plug-in.  Brad Choate is a fine hacker indeed.\n`Jeremy Hedley`_ and `Charles Wiltgen`_ deserve mention for exemplary beta\ntesting of the original SmartyPants.\n\nInternationalization and adaption to Docutils by Günter Milde.\n\n.. _SmartyPants: http://daringfireball.net/projects/smartypants/\n.. _Pyblosxom: http://pyblosxom.bluesock.org/\n.. _Movable Type: http://www.movabletype.org/\n.. _John Gruber: http://daringfireball.net/\n.. _Chad Miller: http://web.chad.org/\n.. _Brad Choate: http://bradchoate.com/\n.. _Jeremy Hedley: http://antipixel.com/\n.. _Charles Wiltgen: http://playbacktime.com/\n.. _Rael Dornfest: http://raelity.org/\n"

Example::\n\n    docutils --parser=markdown --writer=xml --help\n\n\n\n__\n.. _latex2e:\n.. _Generating LaTeX with Docutils: latex.html\n.. _manpage: manpage.html\n.. _Markdown: https://www.markdownguide.org/\n.. _[docutils application]: config.html#docutils-application\n\n\nHTML-Generating Tools\n=====================\n\nbuildhtml.py\n------------\n\n:Readers: Standalone, PEP\n:Parser: reStructuredText\n:Writers: html_, html5_, pep_html_\n:Config_: `[buildhtml application]`_\n\nUse ``buildhtml.py`` to generate ``*.html`` from all the ``*.txt`` files\n(including PEPs) in each <directory> given, and their subdirectories\ntoo.  (Use the ``--local`` option to skip subdirectories.)\n\nUsage::\n\n    buildhtml.py [options] [<directory> ...]\n\nAfter unpacking the Docutils package, the following shell commands\nwill generate HTML for all included documentation::\n\n    cd docutils/tools\n    buildhtml.py ..\n\nFor official releases, the directory may be called \"docutils-X.Y\",\nwhere \"X.Y\" is the release version.  Alternatively::\n\n    cd docutils\n    tools/buildhtml.py --config=tools/docutils.conf\n\nThe current directory (and all subdirectories) is chosen by default if\nno directory is named.  Some files may generate system messages\n(docs/user/rst/demo.txt contains intentional errors); use the\n``--quiet`` option to suppress all warnings.  The ``--config`` option\nensures that the correct settings are in place (a ``docutils.conf``\n`configuration file`_ in the current directory is picked up\nautomatically).  Command-line options may be used to override config\nfile settings or replace them altogether.\n\n.. _[buildhtml application]: config.html#buildhtml-application\n.. _configuration file: `configuration files`_\n\n\nrst2html.py\n-----------\n\n:Reader: Standalone\n:Parser: reStructuredText\n:Writer: html_\n\n`rst2html.py` is the front-end for the default Docutils HTML writer.\nThe default writer may change with the development of HTML, browsers,\nDocutils, and the web. Currently, it is html4css1_.\n\n.. caution::\n   Use a specific front end like rst2html4.py_ or rst2html5.py_,\n   if you depend on stability of the generated HTML code\n   (e.g., because you use a custom style sheet or post-processing\n   that may break otherwise).\n\n\nrst2html4.py\n------------\n\n:Reader: Standalone\n:Parser: reStructuredText\n:Writer: html4css1_\n\nThe ``rst2html4.py`` front end reads standalone reStructuredText source\nfiles and produces `XHTML 1.0 Transitional`_ output.\nA CSS stylesheet is required for proper rendering; a simple but\ncomplete stylesheet is installed and used by default (see Stylesheets_\nbelow).\n\nFor example, to process a reStructuredText file \"``test.txt``\" into\nHTML::\n\n    rst2html.py test.txt test.html\n\nNow open the \"``test.html``\" file in your favorite browser to see the\nresults.  To get a footer with a link to the source file, date & time\nof processing, and links to the Docutils project, add some options::\n\n    rst2html.py -stg test.txt test.html\n\n\nStylesheets\n```````````\n\n``rst2html.py`` inserts into the generated HTML a cascading stylesheet\n(or a link to a stylesheet, when passing the \"``--link-stylesheet``\"\noption).  A stylesheet is required for proper rendering.  The default\nstylesheet (``docutils/writers/html4css1/html4css1.css``, located in\nthe installation directory) is provided for basic use.  To use\ndifferent stylesheet(s), specify the stylesheets' location(s)\nas comma-separated list with the \"``--stylesheet``\" (for a URL)\nor \"``--stylesheet-path``\" (for a local file) command-line option,\nor with `configuration file`_ settings (e.g. ``./docutils.conf``\nor ``~/.docutils``).

The provided style sheets ``minimal.css`` and ``plain.css``\ndefine required and optional styling rules respectively.\n\n.. _html5: html.html#html5-polyglot\n\nrstpep2html.py\n--------------\n\n:Reader: PEP\n:Parser: reStructuredText\n:Writer: pep_html_\n\n``rstpep2html.py`` reads a new-style PEP (marked up with reStructuredText)\nand produces `XHTML 1.0 Transitional`_.  It requires a template file and a\nstylesheet.  By default, it makes use of a \"``pep-html-template``\" file and\nthe \"``pep.css``\" stylesheet (both in the ``docutils/writers/pep_html/``\ndirectory), but these can be overridden by command-line options or\nconfiguration files.\n\nFor example, to process a PEP into HTML::\n\n    cd <path-to-docutils>/docs/peps\n    rstpep2html.py pep-0287.txt pep-0287.html\n\n.. _pep_html: html.html#pep-html\n\nrst2s5.py\n---------\n\n:Reader: Standalone\n:Parser: reStructuredText\n:Writer: s5_html_\n\nThe ``rst2s5.py`` front end reads standalone reStructuredText source\nfiles and produces (X)HTML output compatible with S5_, the \"Simple\nStandards-based Slide Show System\" by Eric Meyer.  A theme is required\nfor proper rendering; several are distributed with Docutils and others\nare available; see Themes_ below.\n\nFor example, to process a reStructuredText file \"``slides.txt``\" into\nS5/HTML::\n\n    rst2s5.py slides.txt slides.html\n\nNow open the \"``slides.html``\" file in your favorite browser, switch\nto full-screen mode, and enjoy the results.\n\n.. _S5: http://meyerweb.com/eric/tools/s5/\n.. _s5_html: html.html#s5-html\n\nThemes\n``````\n\nEach S5 theme consists of a directory containing several files:\nstylesheets, JavaScript, and graphics.  These are copied into a\n``ui/<theme>`` directory beside the generated HTML.  A theme is chosen\nusing the \"``--theme``\" option (for themes that come with Docutils) or\nthe \"``--theme-url``\" option (for themes anywhere).  For example, the\n\"medium-black\" theme can be specified as follows::\n\n    rst2s5.py --theme medium-black slides.txt slides.html\n\nThe theme will be copied to the ``ui/medium-black`` directory.\n\nSeveral themes are included with Docutils:\n\n``default``\n    This is a simplified version of S5's default theme.\n\n    :Main content: black serif text on a white background\n    :Text capacity: about 13 lines\n    :Headers: light blue, bold sans-serif text on a dark blue\n              background; titles are limited to one line\n    :Footers: small, gray, bold sans-serif text on a dark blue\n              background\n\n``small-white``\n    (Small text on a white background.)\n\n    :Main content: black serif text on a white background\n    :Text capacity: about 15 lines\n    :Headers: black, bold sans-serif text on a white background;\n              titles wrap\n    :Footers: small, dark gray, bold sans-serif text on a white\n              background\n\n``small-black``\n    :Main content: white serif text on a black background\n    :Text capacity: about 15 lines\n    :Headers: white, bold sans-serif text on a black background;\n              titles wrap\n    :Footers: small, light gray, bold sans-serif text on a black\n              background\n\n``medium-white``\n    :Main content: black serif text on a white background\n    :Text capacity: about 9 lines\n    :Headers: black, bold sans-serif text on a white background;\n              titles wrap\n    :Footers: small, dark gray, bold sans-serif text on a white\n              background\n\n``medium-black``\n    :Main content: white serif text on a black background\n    :Text capacity: about 9 lines\n    :Headers: white, bold sans-serif text on a black background;\n              titles wrap\n    :Footers: small, light gray, bold sans-serif text on a black\n              background\n\n``big-white``\n    :Main content: black, bold sans-serif text on a white background\n    :Text capacity: about 5 lines\n    :Headers: black, bold sans-serif text on a white background;\n              titles wrap\n    :Footers: not displayed\n\n``big-black``\n    :Main content: white, bold sans-serif text on a black background\n    :Text capacity: about 5 lines\n    :Headers: white, bold sans-serif text on a black background;\n              titles wrap\n    :Footers: not displayed\n\nIf a theme directory contains a file named ``__base__``, the name of\nthe theme's base theme will be read from it.
