If you need to build on top of it to correct\n earlier mistakes, a new topic branch is created by forking at\n the tip of the \"master\". This is not strictly necessary, but\n it makes it easier to keep your history simple.\n\n * Whenever you need to test or publish your changes to topic\n branches, merge them into \"next\" branch.\n\nThe script, being an example, hardcodes the publish branch name\nto be \"next\", but it is trivial to make it configurable via\n$GIT_DIR/config mechanism.\n\nWith this workflow, you would want to know:\n\n(1) ... if a topic branch has ever been merged to \"next\". Young\n topic branches can have stupid mistakes you would rather\n clean up before publishing, and things that have not been\n merged into other branches can be easily rebased without\n affecting other people. But once it is published, you would\n not want to rewind it.\n\n(2) ... if a topic branch has been fully merged to \"master\".\n Then you can delete it. More importantly, you should not\n build on top of it -- other people may already want to\n change things related to the topic as patches against your\n \"master\", so if you need further changes, it is better to\n fork the topic (perhaps with the same name) afresh from the\n tip of \"master\".\n\nLet's look at this example:\n\n\t\t o---o---o---o---o---o---o---o---o---o \"next\"\n\t\t / / / /\n\t\t / a---a---b A / /\n\t\t/ / / /\n\t / / c---c---c---c B /\n\t / / / \\ /\n\t / / / b---b C \\ /\n\t / / / / \\ /\n ---o---o---o---o---o---o---o---o---o---o---o \"master\"\n\n\nA, B and C are topic branches.\n\n * A has one fix since it was merged up to \"next\".\n\n * B has finished. It has been fully merged up to \"master\" and \"next\",\n and is ready to be deleted.\n\n * C has not merged to \"next\" at all.\n\nWe would want to allow C to be rebased, refuse A, and encourage\nB to be deleted.\n\nTo compute (1):\n\n\tgit rev-list ^master ^topic next\n\tgit rev-list ^master next\n\n\tif these match, topic has not merged in next at all.\n\nTo compute (2):\n\n\tgit rev-list master..topic\n\n\tif this is empty, it is fully merged to \"master\".\n\nDOC_END\n" }, { "path": ".git/hooks/pre-receive.sample", "content": "#!/bin/sh\n#\n# An example hook script to make use of push options.\n# The example simply echoes all push options that start with 'echoback='\n# and rejects all pushes when the \"reject\" push option is used.\n#\n# To enable this hook, rename this file to \"pre-receive\".\n\nif test -n \"$GIT_PUSH_OPTION_COUNT\"\nthen\n\ti=0\n\twhile test \"$i\" -lt \"$GIT_PUSH_OPTION_COUNT\"\n\tdo\n\t\teval \"value=\\$GIT_PUSH_OPTION_$i\"\n\t\tcase \"$value\" in\n\t\techoback=*)\n\t\t\techo \"echo from the pre-receive-hook: ${value#*=}\" >&2\n\t\t\t;;\n\t\treject)\n\t\t\texit 1\n\t\tesac\n\t\ti=$((i + 1))\n\tdone\nfi\n" }, { "path": ".git/hooks/prepare-commit-msg.sample", "content": "#!/bin/sh\n#\n# An example hook script to prepare the commit log message.\n# Called by \"git commit\" with the name of the file that has the\n# commit message, followed by the description of the commit\n# message's source.

Build once (only if `./v` is missing): `make`\n2. Build a working compiler:\n * Debug-friendly (recommended): `./v -g -keepc -o ./vnew cmd/v`\n3. Use `./vnew` for everything:\n * Run a file: `./vnew run examples/hello_world.v`\n * Run tests: `./vnew -silent test vlib/v/`\n * Format: `./vnew fmt -w path/to/file.v`\n\nThen read Top Rules and Agent Rules before making changes.\n\n## Top Rules\n* Use `./v` only to build `./vnew`; use `./vnew` for everything else.\n* Put all V flags immediately after `./vnew` and before the\n subcommand/file, e.g. `./vnew -g run file.v`\n (not `./vnew run file.v -g`); flags after the subcommand are passed\n to that subcommand.\n* Rebuild `./vnew` after compiler or core module changes\n (see Build & Rebuild).\n* Run the smallest relevant tests; see Testing for triggers and\n minimums.\n* Ask before large refactors or wide file touches (see Agent Rules).\n* Do not stash or modify unrelated files unless explicitly instructed.\n* This guide assumes agents run locally, not in CI; CI notes are\n informational only.\n* When a summary is required, include behavior change, tests run, and\n touched file paths.\n* If instructions overlap, prefer Build & Rebuild, Testing, and\n Reporting.\n* If duplicates drift, treat Build & Rebuild, Testing, and Reporting as\n canonical and align other sections to them.\n\n## Agent Rules\n\n### Repo root\nAll commands assume the repo root as the working directory. The default\nlocation is `/opt/v`, but this may differ in your environment. If a\ncommand fails due to missing paths, verify with `pwd` and adjust\naccordingly. Use a per-command workdir only when a task requires a\nsubdir.\n\n### Tone and output\n* Be concise by default. If the user asks for depth, provide it while\n keeping structure tight.\n* Keep output easy to scan: short sections, bullets when listing,\n commands in backticks, no filler.\n* Use a strict, operational tone unless higher-priority instructions\n override it.\n* Ask only when required. If information is missing, ask a direct\n question.\n\n### File access and edit scope\n* You may read and edit all files in the V repo without asking for\n permission. This is file access, not change scope; scope is\n constrained below. Reading is always OK.\n Edits to `ci/` or `Dockerfile*` still require an explicit ask.\n* Run build, test, and format commands without asking for permission.\n These are validation steps, not code changes. Only ask about edit\n scope, not about running `fmt`, targeted tests, or `check-md`.\n* Only modify files required for the user request; avoid unrelated\n refactors. If duplication is harmful, small refactors to remove it\n are OK only when needed. Only refactor duplication in code you are\n already touching, and only when it directly supports the request or\n fixes a bug there. \"Touching\" means files already modified for the\n request.\n* Avoid unrelated file changes; call them out if present.\n* Avoid touching `thirdparty/` unless explicitly requested. If changes\n are needed there, ask for approval before proceeding.\n\n### When to ask\n* Ask before large refactors or wide file touches (more than 5 files,\n or changes across multiple repo-root directories like `cmd/`, `vlib/`,\n `doc/`, `examples/`).\n Exception: docs-only changes across many files are OK without asking;\n call them out in the summary.\n* Ask before large behavioral changes within a single subsystem or file,\n even if the file count is small. Examples: changes to parser rules,\n checker resolution, codegen output shape, diagnostic text/ordering, or\n tool CLI behavior. Large means user-visible changes in CLI flags,\n output, diagnostics, or codegen shape. If unsure whether a change is\n \"large,\" ask.\n* Ask before touching `ci/` or `Dockerfile*` unless explicitly\n requested. If changes are needed there, confirm whether local\n validation is expected or if CI-only coverage is acceptable.\n\n### Bootstrap\n* Bootstrap/compiler usage rules: see Top Rules and Build & Rebuild.\n\n### Completeness and summaries\n* If you cannot complete a requested step, state the blocker and partial\n progress (what was attempted and what remains).\n* After substantial work, provide a short summary and list touched file\n paths. Substantial work means any behavioral change, or changes in\n more than one file. Always include tests run (or \"Not run\" with\n reason) in the summary.\n* Never change tests just to silence failures. Update expectations only\n when behavior changes are intended, and note the rationale in the\n summary.\n\n### New files and deeper guidance\n* New file checklist: format with `./vnew fmt -w`, add doc comments for\n any public functions, run `./vnew check-md` for markdown files, and\n keep Markdown lines <= 100 chars. Add or update tests when introducing\n a new public API.\n* For deeper edge cases, consult `CONTRIBUTING.md` and `TESTS.md`.\n\n## Safety (Do Not Brick the Repo)\n* Do not overwrite the working `./v` binary.\n * Never run `./v self` without `-o`.\n * Build with `./v -o ./vnew cmd/v`, then use `./vnew` for all checks.\n* Keep generated C when debugging backend issues: add `-keepc`.\n* Avoid hidden/bidirectional Unicode characters in source/markdown\n files.\n* If the compiler becomes unusable, recover with:\n 1. `git stash`\n 2. `make`\n 3. `git stash apply`\n Check `git status` before stashing to avoid hiding unrelated work.\n Do not stash unless explicitly instructed or the compiler is bricked.\n\n## Divergences From Repo Docs\nThe repo docs use `v` in examples. In this environment:\n* Use `./v -g -keepc -o ./vnew cmd/v` instead of `v self`.\n* Use `./vnew` for all builds, runs, and tests.\n* `TESTS.md` suggests `v test-all` before PRs; ask before running\n `./vnew test-all`.\nThese overrides exist to keep agent workflows reproducible and to avoid\nbreaking the bootstrap compiler.\n\n## Quick Decisions\n* For rebuild and test choices, follow Build & Rebuild and Testing.\n* Follow Common Workflow for the default execution order.\n* For broader workflow guidance, see `CONTRIBUTING.md`.\n\n### Compact decision table (rebuild/tests)\nUse this table to pick the minimum rebuild/tests quickly. See Build &\nRebuild and Testing for full details and edge cases.\nCommands omit `./vnew` for brevity; assume the `./vnew` prefix.\nThis table is the minimum set; check Testing for additional triggers.\nREPL and backend changes have additional triggers in Testing.\nNote: `cmd/v/` is compiler scope; treat changes there as compiler\nchanges.\nWhen in doubt, ask before proceeding.\nIf you read only one section for tests, **read Testing**.\n\n| Change area | Rebuild? | Minimum tests to run |\n| --- | --- | --- |\n| Docs only (`.md`) | No | `check-md file.md` |\n| Compiler (`vlib/v/`, `cmd/v/`) | Yes | `-silent vlib/v/compiler_errors_test.v`; `test vlib/v/` |\n| Core modules (builtin/strings/os/strconv/time) | Yes | Smallest relevant tests |\n| Parser-only (`vlib/v/parser/`) | Yes | `test vlib/v/parser/` |\n| Checker-only (`vlib/v/checker/`) | Yes | `test vlib/v/checker/` |\n| Comptime (`vlib/v/comptime/`) | Yes | `test vlib/v/tests/`; comptime-related tests |\n| vlib (non-compiler) | No | Nearest `*_test.v` or `test vlib/path/` |\n| Tools (`cmd/tools/`) | No | Tool-specific test; else nearest `*_test.v` |\n| Diagnostic/output changes | Yes | `vlib/v/slow_tests/inout/compiler_test.v` |\n| C codegen (`vlib/v/gen/c/`) | Yes | `vlib/v/gen/c/coutput_test.v` |\n\n## Common Workflow\n0. Before work: `git status`; ensure `./vnew` exists; rebuild if needed.\n If `./vnew` is missing, see Quick Start or Build & Rebuild.\n1. Edit the relevant files.\n2. If compiler sources or core modules changed, rebuild `./vnew` with\n `./v -g -keepc -o ./vnew cmd/v` (see Build & Rebuild).\n3. Format touched `.v`/`.vsh` files and run `./vnew check-md` on\n touched markdown.\n4. Run the smallest relevant tests for the change scope (see Testing).\n\nSee Build & Rebuild for rebuild triggers and flags.\n\n## Reporting\n* When a summary is required (see Agent Rules), it must include:\n * Behavior changes (or \"No behavior change\").\n * Tests run (or \"Not run\" with a reason).\n * Touched file paths.\n * Note unrelated changes if present.\n * Note doc updates if public behavior/tool output changed.\n* If public behavior or tool output changes, update relevant docs\n (README.md, `doc/`, `tutorials/`) and note it.\n For example: README.md for top-level CLI usage, `doc/` for\n compiler/tool docs, `tutorials/` for learning material.\n* If you add or change a public API, update module docs or README and\n note it. Public API includes stdlib functions/types and user-visible\n compiler flags, diagnostics, tool CLI behavior (including `cmd/tools`\n and stdlib CLI tools), or output formats.\n* Update `CHANGELOG.md` or `ROADMAP.md` only when explicitly requested.\n* Public behavior includes compiler output, diagnostics, user-facing\n CLI, and stdlib API. This includes developer-facing flags, error\n codes, or output ordering changes.\n* Internal refactors with no public behavior change do not require doc\n updates.\n* If unsure whether behavior is public, ask the user before updating\n docs.\n* Acceptable reasons for not running tests: docs-only change, no\n relevant tests, or environment constraints. Be specific.\n* Docs-only changes: run `./vnew check-md file.md`; no other tests\n required unless a test explicitly reads those docs.\n No rebuild is needed unless compiler or core modules changed.\n* For docs-only, explicitly mention `check-md` in the summary.\n* If you update `.out` files, state the rationale in the summary.\n* Do not update `.out` files unless a behavior change is intended;\n otherwise treat mismatches as regressions.\n* Example summary line: `Behavior change: none` or\n `Behavior change: fixed X`.\n* Behavior change includes output, API, error messages, and test\n expectations.\n* If blocked, note what was attempted and why it failed.\n* If tooling/network restrictions block a step, state the restriction\n and the closest viable alternative.\n* Use `git status` to confirm touched files before reporting.\n\n## Prerequisites\n* Toolchain: `make`, `git`, and a C compiler (`clang` or `gcc`).\n* Windows: use `make.bat` for the initial build.\n\n## Build & Rebuild\n* Initial build (only if `./v` is missing): `make`\n (Windows: `make.bat`).\n* Build `./vnew` (debug-friendly, recommended for agent workflows):\n `./v -g -keepc -o ./vnew cmd/v`\n* Never run `./v self` directly; only build `./vnew` with the commands\n above.\n* If `./v` is missing, run `make` first, then build `./vnew`.\n* If `./vnew` is missing but `./v` exists, run `./v -o ./vnew cmd/v`.\n* This section is the source of truth for rebuild triggers.\n If a rule appears elsewhere, defer to this section.\n* Rebuild triggers:\n * Compiler sources in `vlib/v/` or `cmd/v/`.\n * Core modules: `builtin`, `strings`, `os`, `strconv`, `time`.\n* If `./v` exists but compiler sources changed, still rebuild `./vnew`\n before tests.\n* If unsure whether compiler/core changes happened, rebuild `./vnew`.\n* Common flags:\n * `-g` debug info (V line numbers).\n * `-cg` debug info (C line numbers); often combined with `-keepc`.\n * `-keepc` keep generated C file(s).\n * `-prod` optimized build.\n * `-o file` output path/name.\n * `-cc clang` pick a C compiler.\n * `-cstrict` be stricter about the generated C.\n * `-b js|native|wasm` select a backend.\n * `-os ` cross-compile target selection (when supported).\n\n## Code Style\n* Comments: add succinct comments only when code is not self-explanatory.\n Do not delete existing comments unless they are incorrect; you may fix\n grammar or spelling without changing meaning.\n Add V doc comments right before each new or modified public function\n or method.\n The V doc comments should start with the name of the fn,\n example: `// the_name does ...`\n* Copy pasta: avoid copy pasta. If there's duplicate logic, move to a\n function only when it is required for the request and within code you\n are already touching.\n* Avoid using `unsafe{ code }` blocks where possible, and minimize\n their scope. `unsafe` is acceptable for low-level interop (e.g. C\n pointer casts, manual memory management) but should never wrap\n ordinary V logic. When `unsafe` is required, keep the block as small\n as possible and add a comment explaining why it is necessary.\n* Keep Markdown lines <= 100 chars (the checker is strict).\n Apply to touched lines in modified Markdown files.\n* Avoid hidden/bidirectional Unicode characters in source/markdown\n files.\n* Non-V files: keep existing formatting; only reformat if required by\n the change.\n* Treat `.vv` files in `vlib/v/slow_tests/inout/` as fixtures; avoid\n formatting unless a behavior change is intended and output\n expectations are updated.\n* Formatting and check commands are in Tools.\n\n## Modules and Imports\n* Module names must match their directory name (no hierarchy in the\n `module` line). Mismatches cause silent import failures.\n* Imports follow the folder hierarchy (e.g. `import abc.def`).\n\n## C/JS Interop Hygiene\n* Avoid using `C.` or `JS.` symbols in plain `.v` files.\n * Use `.c.v` / `.js.v` files.\n * Enable `-Wimpure-v` to catch accidental impurity.\n* Do not refactor existing `C.`/`JS.` uses in `.v` files unless\n required. If you must change those lines, prefer moving the interop\n code to `.c.v`/`.js.v`.\n* For C interop, use correct `const_` prefixes in C function\n redeclarations when needed (helps with `-cstrict` and C static\n analysis tooling).\n\n## Environment-Specific Code (files and `$if`)\nV supports environment-specific file suffixes. Prefer them when the\nwhole file is platform/backend specific.\n\nCommon patterns:\n* Backend splits:\n * `*.c.v` (C backend), `*.js.v` (JS backend), `*.native.v` (native\n backend), `*.wasm.v` (WASM backend)\n* OS splits:\n * `*_windows.c.v`, `*_linux.c.v`, `*_nix.c.v`, with `*_default.c.v`\n as fallback\n* Flag splits:\n * `*_d_customflag.v` is included only with `-d customflag`\n * `*_notd_customflag.v` is included only when that flag is NOT passed\n\nNotes:\n* Do not use combinatorial suffixes like `_d_flag_linux.c.v`; use\n `_d_flag.v` plus `$if linux {}` inside the file.\n* For smaller platform differences, use compile-time `$if` blocks:\n * `$if windows { ... } $else { ... }`\n* See Compile-Time Code and Reflection for the full `$if` reference.\n\n## Compile-Time Code and Reflection\nV uses `$` as a prefix for compile-time (comptime) operations. These\nare evaluated by the compiler, not at runtime. AI agents frequently\nconfuse comptime and runtime constructs; this section clarifies the\nboundaries.\n\n### Compile-time `$if`\n`$if` evaluates conditions at compile time. It is not a runtime `if`.\nUse it for platform, compiler, and custom-flag checks:\n* `$if windows { ... } $else $if linux { ... } $else { ... }`\n* `$if debug { ... }` (enabled by `-g` or `-cg`)\n* `$if prod { ... }` (enabled by `-prod`)\n* `$if custom_flag ? { ... }` (enabled by `-d custom_flag`)\n\nFull list of builtin `$if` options: see the table at\n.\n\nCommon mistakes:\n* Using runtime `if` where `$if` is needed for platform-specific code.\n Runtime `if` will fail to compile if it references platform-specific\n symbols; `$if` excludes the block entirely on non-matching platforms.\n* Forgetting the `?` suffix for custom flags: `$if myflag ? { ... }`.\n Without `?`, the compiler treats it as a builtin option and silently\n ignores it.\n\n### Compile-time `$for`\n`$for` iterates over type metadata at compile time. It works with:\n* `StructType.fields` - iterate struct fields\n* `StructType.methods` - iterate struct methods\n* `EnumType.values` - iterate enum values\n* `StructType.attributes` - iterate struct attributes\n* `SumType.variants` - iterate sum type variants\n* `method.params` - iterate method parameters\n\nInside `$for` blocks, use `$if` to branch on field/method types:\n```v oksyntax\nfn main() {\n\t$for field in MyStruct.fields {\n\t\t$if field.typ is string {\n\t\t\tprintln(field.name)\n\t\t}\n\t}\n}\n```\n\nAlso works with generics: `T.fields`, `param.fields` where\n`fn gen[T](param T) {}`.\n\nCommon mistakes:\n* Using runtime `for` to iterate struct fields. This does not work;\n V has no runtime reflection. Always use `$for`.\n* Calling `obj.$method()` outside a `$for m in Type.methods` block.\n The `$method()` call is only valid inside a comptime method\n iteration.\n* Assuming comptime `$for` produces a runtime loop. It does not; the\n compiler unrolls it into concrete code for each field/method/variant.\n\n### Compile-time functions\nOnly the following `$`-prefixed functions are supported:\n* `$embed_file('path')` - embed a file's contents into the binary.\n Paths can be absolute, relative to the source file, or use pseudo\n variables like `@VEXEROOT` or `@VMODROOT`.\n* `$tmpl('path')` - compile a V template file (used by vweb/veb).\n* `$env('VAR')` - read an environment variable at compile time.\n* `$d('ident', default)` - read a `-d ident=value` compile-time\n define, with a default fallback.\n* `$res('path')` - embed a resource (Android).\n* `$compile_error('msg')` - emit a compile-time error.\n* `$compile_warn('msg')` - emit a compile-time warning.\n* `$pkgconfig('name')` - query pkg-config at compile time.\n\nCommon mistakes:\n* Inventing comptime functions that do not exist (e.g. `$typeof`,\n `$sizeof` as comptime calls). Use `typeof(expr).name` and\n `sizeof(Type)` instead; these are builtins, not `$`-prefixed.\n* Assuming `$embed_file` returns a string. It returns an\n `EmbedFileData` object; use `.to_string()` or `.to_bytes()`.\n* Using `$env` where a runtime `os.getenv` is appropriate, or vice\n versa. `$env` is baked in at compile time and cannot change at\n runtime.\n\n### Compile-time pseudo variables\nThese are `@`-prefixed identifiers substituted at compile time:\n* `@FN` - current function name.\n* `@METHOD` - `ReceiverType.MethodName`.\n* `@MOD` - current module name.\n* `@STRUCT` - current struct name.\n* `@FILE`, `@DIR`, `@LINE`, `@COLUMN`, `@FILE_LINE` - source\n location.\n* `@LOCATION` - file, line, and current type+method; good for logging.\n* `@VEXE`, `@VEXEROOT` - path to the V compiler and its directory.\n* `@VHASH`, `@VCURRENTHASH` - compiler commit hashes.\n* `@VMOD_FILE`, `@VMODHASH`, `@VMODROOT` - nearest `v.mod` info.\n* `@BUILD_DATE`, `@BUILD_TIME`, `@BUILD_TIMESTAMP` - build time (UTC).\n Override with the `SOURCE_DATE_EPOCH` env var for reproducible\n builds.\n* `@OS`, `@CCOMPILER`, `@BACKEND`, `@PLATFORM` - build environment.\n\n### Compile-time type groups\nComptime type groups combine multiple types into a higher-level type\nfor use in generic or comptime `$if` checks:\n* `$int` - all integer types\n* `$float` - all float types\n* `$array` - all array types\n* `$map` - all map types\n* `$struct` - all struct types\n* `$enum` - all enum types\n* `$alias` - all type aliases\n* `$sumtype` - all sum types\n* `$function` - all function types\n* `$interface` - all interface types\n* `$option` - all option types\n\nExample: `$if field.typ is $int { ... }`\n\n### Comptime changes and testing\nComptime logic lives in `vlib/v/comptime/` and is exercised by the\nchecker, parser, and cgen stages. Changes here require a rebuild of\n`./vnew` and should be tested with `./vnew -silent test vlib/v/tests/` plus\nany comptime-specific tests. See the decision table and Testing.\n\n## Run Programs\n* Compile and run: `./vnew run file.v`.\n* Just compile: `./vnew file.v` (creates executable).\n* With debug info: `./vnew -g run file.v`.\n* Debug run (C line numbers): `./vnew -keepc -cg run file.v`.\n* Example: `./vnew run examples/hello_world.v`.\n\n## Testing\nRun:\n* File (shows test output): `./vnew path/to/file_test.v`.\n* File (test runner report only): `./vnew test path/to/file_test.v`.\n* Dir: `./vnew -silent test path/to/dir/`.\n* Dir with statistics/metrics: `./vnew -stats test path/to/dir/`.\n* Compiler: `./vnew -silent vlib/v/compiler_errors_test.v`.\n* Fix outputs (only when intended):\n `VAUTOFIX=1 ./vnew -silent vlib/v/compiler_errors_test.v`.\n* All: `./vnew test-all`.\n Ask before running `./vnew test-all` unless explicitly requested.\n\nWhen:\n* Rule of thumb: for localized changes, run the smallest relevant\n tests. If any trigger below matches, run the listed tests.\n* Minimum tests listed are the floor, not the ceiling; add targeted\n tests for cross-cutting changes.\n* If unsure which tests apply, ask the user before proceeding.\n* If in doubt, prefer the smallest targeted test and ask.\n* Run all tests that apply. Start with the smallest targeted tests;\n add slow tests as needed. Order does not matter.\n* Compiler changes (`vlib/v/` or `cmd/v/`):\n Run `./vnew -silent vlib/v/compiler_errors_test.v`,\n `./vnew -silent test vlib/v/`.\n* Parser-only changes (`vlib/v/parser/`):\n Run `./vnew -silent test vlib/v/parser/`.\n* Checker-only changes (`vlib/v/checker`):\n Run `./vnew -silent test vlib/v/checker/`.\n* vlib changes: Run nearest `*_test.v` or\n `./vnew -silent test vlib/path/`.\n* Tool changes (`cmd/tools/`): Run tool-specific tests. If none exist,\n run the smallest relevant `*_test.v` that exercises the tool.\n Note: `cmd/v/` is compiler scope, not tools.\n Examples: `cmd/tools/vfmt` -> `vlib/v/fmt/fmt_test.v` .\n `cmd/tools/vdoc` -> `cmd/tools/vdoc/vdoc_test.v`.\n* Diagnostic/output changes:\n Run `./vnew -silent vlib/v/slow_tests/inout/compiler_test.v`.\n* C codegen changes: Run `./vnew -silent vlib/v/gen/c/coutput_test.v`.\n Consider a stricter validation pass:\n `./vnew -cstrict -cc clang -silent test vlib/v/`.\n* REPL changes: Run `./vnew -silent vlib/v/slow_tests/repl/repl_test.v`.\n* Broad refactors: Run `./vnew -silent test-all`.\n* Backend-specific changes: run the smallest relevant tests for the\n affected backend. JS/native/WASM backends are incomplete, so avoid\n broad `-b test vlib/` runs. Prefer targeted `*_test.v`\n files or small test dirs with `-b js|native|wasm`.\n\nIf time-constrained, prioritize\n`./vnew -silent vlib/v/compiler_errors_test.v` and the smallest targeted tests.\nRun `vlib/v/slow_tests/inout/compiler_test.v`\nand `vlib/v/gen/c/coutput_test.v` when output or codegen changes are\nlikely.\nSee `TESTS.md` for more guidance on test selection and output\nexpectations.\nSee `CONTRIBUTING.md` for broader workflow guidance.\n\nConcrete triggers:\n* `vlib/v/slow_tests/inout/compiler_test.v` when error text or output\n formatting changes, or changes in checker/parser error reporting.\n* `vlib/v/gen/c/coutput_test.v` for changes under `vlib/v/gen/c/` or\n C codegen output paths.\n\nTypes:\n* Standard: `*_test.v` files with `test_` functions.\n* Output: `.vv` source + `.out` expected output in\n `vlib/v/slow_tests/inout/`.\n Example: `./vnew -silent vlib/v/slow_tests/inout/compiler_test.v`.\n* `vlib/v/tests/**` may use `.run.out` expectations; run with\n `./vnew -silent test vlib/v/tests`.\n\nDocs-only guidance: see Reporting.\nIf time-boxed, run at least the smallest relevant test and note\nskipped coverage in the summary.\n\n### Useful env variables and flags while testing\n* `VAUTOFIX=1` - Auto-update .out files when tests fail (run twice).\n Use only when a behavior change is intended.\n* `VTEST_ONLY=glob_pattern` - Run only tests matching pattern.\n* `VTEST_HIDE_OK=1` - Hide successful tests, show only failures.\n* `./vnew -silent test path/to/dir/` - Show only failed tests (if any), and a summary report.\n* `-cc tcc` can speed test builds when TCC is available.\n* Output expectations: update `.out` files only when behavior changes\n are intended; note the rationale in the summary.\n\n## Debug\n* See what the C compiler is doing:\n * `-showcc` prints the C compile command.\n * `-show-c-output` prints the C compiler output.\n* Build a temporary compiler for debug flags:\n * `./vnew -o ./w -d trace_checker cmd/v`\n * Then run: `./w file.v`\n* Keep and inspect generated C:\n * `-keepc -cg` is the common combo.\n * `-printfn -o file.c` emits only the named C function to standart\n output. The `name` uses the `modulename__fnname` format (e.g.\n `main__main`). This flag can be repeated to print multiple\n functions. Methods/generics may use more complex C names; use\n `-keepc` to confirm exact symbols.\n* Trace stages:\n `-d trace_scanner|trace_parser|trace_checker|trace_gen`.\n These flags can help diagnose a problem when a stage stops earlier\n than expected.\n* Time stages: `-d time_parsing|time_checking`.\n* V panics: `-keepc -g`.\n* C segfaults: `-keepc -cg -cc clang`.\n* JS/native/wasm: prefer small, focused test files with\n `-b js|native|wasm` and `-show-c-output` where applicable; avoid\n broad `-b test vlib/`.\n* Quick code location technique:\n When debugging code generation issues, add unique comment tags to\n relevant code generation points (e.g., `/*tom51*/`) in the compiler\n source. Rebuild and generate C code, then search the generated file for these\n tags to quickly map generated C code back to the exact compiler source\n location. This is especially useful when multiple code paths generate\n similar-looking output and you need to identify which path is actually used.\n Example:\n ```v\n // In vlib/v/gen/c/assign.v:\n g.write('builtin___option_ok/*tom51*/(&(${styp}[]) { ')\n\n // After rebuild, search generated C code for \"tom51\":\n // builtin___option_ok/*tom51*/(&(int[]) { ... });\n ```\n Remember to remove these debug tags after fixing the issue.\n\n## Compiler Architecture\nThe V compiler has the following stages, orchestrated by the\n`v.builder` module:\n`v.scanner` -> `v.parser` -> `v.checker` -> `v.transformer` ->\n`v.markused` -> `v.gen.c`\nTheir corresponding folders are: vlib/v/scanner, vlib/v/parser,\nvlib/v/checker, vlib/v/transformer, vlib/v/markused, vlib/v/gen/c .\nThere are additional subsystems (supporting or optional compiler\nmodules) like v.comptime, v.generics, v.pref, v.reflection,\nv.callgraph, etc.\n\n### Key Directories\n* `vlib/`: Standard library (changes here can affect the compiler\n itself).\n* `cmd/v/v.v`: Compiler entry.\n* `cmd/tools/`: vfmt, vdoc, vup, vquest, etc.\n* `examples/`: Example programs.\n* `thirdparty/`: Bundled C libraries (tcc, mbedtls, sokol, etc.).\n* `vlib/v/`: Compiler modules.\n * ast/ - AST node definitions\n * fmt/ - Code formatter\n * scanner/ - Tokenizer\n * token/ - Token definitions\n * parser/ - Produces AST from tokens\n * checker/ - Type checking and resolution\n * comptime/ - Compile-time evaluation support\n * transformer/ - Common optimisations and simplifications, makes the\n backends simpler\n * markused/ - Dead code eliminator\n * gen/c/ - C code generation (primary backend, known as cgen)\n * gen/js/ - JavaScript backend\n * gen/native/ - Machine code generation (ELF, Mach-O)\n * gen/wasm/ - WebAssembly backend\n\n### Test Locations\n* `vlib/v/tests/`: Compiler feature tests (including comptime).\n* `vlib/v/slow_tests/`: Output-matching and slow tests for the\n compiler.\n* `vlib/v/slow_tests/inout/` - Output comparison tests\n (.vv + .out pairs)\n* `vlib/v/parser/` - Parser error tests\n* `vlib/v/checker/` - Checker error tests\n* `vlib/v/gen/c/testdata/` - C codegen tests (.vv + .c.must_have)\n* `examples/compiletime/` - Comptime usage examples (including\n `reflection.v`)\n\n## Error Reporting (checker/parser)\n* Error: `c.error('message', pos)` - hard error, stops compilation.\n* Warning: `c.warn('message', pos)` - warning, allows compilation.\n* Notice: `c.note('message', pos)` - informational only.\n* Pattern: Most checker methods use `fn (mut c Checker)` receiver.\n* Location: `vlib/v/checker/errors.v`.\n\n## Option/Result Types\n* Syntax: `?Type` (optional, can be none) vs `!Type` (result, can\n error).\n* Common bugs: Unwrapping in if guards, struct init with option fields,\n ternaries with options.\n* When changing option/result behavior, add a regression test in\n `vlib/v/tests/`.\n* Tests: Search `vlib/v/tests/` for option/result test files.\n* Pitfall: Options in ternaries, SQL statements, and fixed arrays need\n special handling in cgen.\n\n## Tools\n* Note: if a rule overlaps with Testing, follow Testing.\n* Format: `./vnew fmt -w ` for touched `.v` and `.vsh` files.\n Format only touched files unless explicitly asked to reformat broader\n scope.\n* Treat new files as touched for formatting and markdown checks.\n* Check *all* files are formatted: `./vnew -silent test-fmt`.\n Run only when asked or when validating the full tree.\n* Check markdown: `./vnew check-md file.md` for touched `.md` files\n (required before commits).\n* Code style checker: `./vnew vet vlib/v`\n Run only when asked or when making broad checker changes (more than\n 3 files in `vlib/v/checker/`).\n* Module docs: `./vnew doc -readme -all -l module_name`.\n* Search: `rg pattern` (or `git grep`); list files: `rg --files`.\n* Auto-format hook: `./vnew git-fmt-hook install`.\n\n## Commits and PRs\n* See `CONTRIBUTING.md` for full commit message conventions and PR\n workflow.\n* Keep commits focused: one logical change per commit.\n* If your branch has diverged and a rebase or merge is needed, do not\n force-push or drop hunks without asking. State the conflict and let\n the user decide the resolution strategy. When in doubt, prefer\n `git rebase` over `git merge` for a linear history, but always ask\n if the situation is ambiguous.\n\n## Environment Variables\n* VFLAGS: Pass flags to all V invocations\n (e.g., `VFLAGS='-g' ./vnew test-all`).\n* VEXE: Path to V compiler executable (useful in CI/scripts).\n* TMPDIR: Controls where `.tmp.c` files are written (V uses\n `TMPDIR/v/`).\n* SOURCE_DATE_EPOCH: Override build timestamp for reproducible builds\n (affects `@BUILD_DATE`, `@BUILD_TIME`, `@BUILD_TIMESTAMP`).\n* V2-specific: `V2CC`, `V2CFLAGS`, `V2VERBOSE` (for v2 development).\n\n## Gotchas\n* Core modules (`builtin`, `strings`, `os`, `strconv`, `time`) can\n affect the compiler because it is a V program. Rebuild `./vnew` when\n they change.\n* Module names must match their directory name; mismatches cause silent\n import failures. See Modules and Imports.\n* Some V programs and tools hardcode `os.execute('v ...')` in their\n source. The `./vnew` workflow does not protect against these; if you\n encounter unexpected behavior from such calls, check whether the\n code is invoking the system `v` instead of `./vnew` and adjust\n accordingly.\n* Stale `./vnew` can cause confusing failures; rebuild if behavior\n seems off.\n* Output tests require exact matches; whitespace changes break tests.\n* Formatting reminders: follow Code Style for `fmt` and `check-md`.\n* C compilation errors? Check generated C with `-keepc`\n (creates `/tmp/*.tmp.c`; see also TMPDIR in Environment Variables).\n* Compile-time code (`$if`, `$for`, `$embed_file`, etc.) is a common\n source of AI mistakes. See Compile-Time Code and Reflection for\n correct usage and pitfalls.\n* Broken compiler? See Safety for the recovery sequence.\n* Consult `CONTRIBUTING.md` and `TESTS.md` for:\n * New tests or test infra changes.\n * Output tests or `.out` updates.\n * Broad refactors or compiler-wide changes.\n * Unsure which slow test runner applies to your change.\n" }, { "path": "CHANGELOG.md", "content": "## V 0.5.1\n\n*9 Mar 2026*\n\n#### Improvements in the language\n\n- New clean and fast

Only Linux/macOS for now, requires `-use-coroutines` and\n `coroutines.sleep()` instead of `time.sleep()`. They work with IO and net, but not with GC\n for now.\n- `spawn` now spawns system threads, `go` spawns coroutines.\n- Static type methods: `Foo.new()` to replace factory functions like `new_foo()`.\n- Smartcasting with complex conditions:\n `if sum_type is Foo && !sum_type.is_info && get_name(sum_type.info.name) == 'foo' `.\n- Functions can now return fixed size arrays.\n- Enum values now can have attributes.\n- Generic functions as function parameters are now supported: `fn f[T](x T, i int, f_ Fn[T]) T { `.\n- Anonymous structs can no longer have attributes.\n\n#### Breaking changes\n\n- `byte` deprecated in favor of `u8` (`byte` is automatically converted to `u8` by vfmt).\n\n#### Checker improvements/fixes\n\n- Disallow `Result` type aliases (`type Foo = !Bar`) and `Result` in maps (`map[key]!Type`).\n- Add a missing check for taking address of literal value member.\n- Fixed map initialization for maps with option values.\n- Allow `a << none`, where `a` is `[]?&int`.\n- Disallow multiple `else` branches in a match.\n- Fix index expression with sumtype of array types.\n- Remove hardcoded check for function calls for `C.stat`, `C.sigaction`, etc.\n- Fix multiple embedded external module interface.\n- Fix missing check for diff type on map value declaration.\n- Simplify error handling in the checker (#18507).\n- Option alias fixes.\n- Fix alias to struct ptr on struct init.\n- Sumtypes can no longer hold references.\n- Fix a bug checking generic closures.\n- A hard to reach limit of 1 million iterations for resolving all generics.\n- Fix missing check for unwrapped shift operation.\n- Fix enum max value validation.\n- Add a missing mutability check for `array.delete` calls.\n- Disallow `_ = <- quit`.\n- Disallow type matching with primitive vars.\n- Warning instead of error for unnecessary brackets in if/match.\n- Include import aliases when checking for import duplicates.\n- Fix inferring generic array type in nested call.\n- Allow casted `enum val` and `const` as fixed array size.\n- Disallow multiple return values in const declarations.\n- Fix contains() with array of interfaces.\n- Disallow mut for blank idents.\n\n#### Standard library\n\n- json: Enum value string serialization supports `[json:'alias']` to change its string values.\n- Struct fields can now be skipped during JSON/ORM serialization via `[json:'-']` and `[sql:'-']`,\n in addition to `[skip]`. This allows having custom behavior for different serialization methods.\n- builtin: heap usage API (gc_memory_use() and gc_heap_usage())\n- math.big: refactoring, gcd fixes/improvements, overflow fixes, `mod_inverse`.\n- flag: fix finalize with multiple shortargs.\n- runtime: add new functions total_memory/0 and free_memory/0.\n- time: small cleanup of parse_iso8601 comments, make the C.strftime declaration forwards compatible\n- stbi: allow customization of number of channels in `stbi.load()`.\n- stbi: add a `resize_uint8` function for resizing images in memory.\n- time, x.json2: improve iso8601 time decoding.\n- builtin: zero out internal map/array pointers on m.free(), to reduce the work for the GC\n mark phase for non escaping maps/arrays, used in hot loops.\n- time: add more detailed error descriptions, add custom format parsing with time.parse_format.\n- sync: add Mutex.destroy and RwMutex.destroy methods.\n- datatypes: add Bloom filter.\n- rand: add missing rand.u16(), update doc comments, add test.\n- builtin: speed up string methods with vmemcpy instead of `for` loop for copying data.\n\n#### Web\n\n- The builtin websocket library is now thread safe.\n- Enhanced builtin csrf protection in vweb.\n- vweb: ability to set and get values on vweb.Context.\n- vweb: support for host specific static files.\n- vweb: host option added to controller, and a new host attribute.\n- vweb: middleware docs improved; same with docs for `[vweb_global]` and `shared`.\n- vweb: return 404 on file not found.\n- net.http: copy IANA's list of methods to the http.Method enum.\n- net.conv: use a pure V implementation instead of C.hton etc.\n- net.html: `get_tag()` methods to find first tag occurrence.\n- net.html: fixed text parsing for inline tags.\n- net.html: fix parsing of nested quoted strings in code tags.\n- picoev: FreeBSD support.\n\n#### ORM\n\n- Fixed a foreign key bug that could result in an extra insert.\n- Comptime bug with `[skip]` and `[sql:'-']` fixed.\n- Checker error for unsupported field types.\n- Allow structs without the id field, more flexible primary keys.\n- Improved docs and examples.\n- Uninitialized structs are no longer inserted into related tables.\n\n#### Database drivers\n\n- mysql: TIMESTAMP support.\n- mysql: allocate memory for each string and blob dynamically depending on its value length.\n- mysql: add the ability to commit transactions.\n\n#### Native backend\n\n- Refactoring, splitting large files into multiple.\n\n#### C backend\n\n- Fix code generation for generic unions.\n- Fix `[N]chan` (fixed arrays of channels).\n- Fix nested fixed array instantiation.\n- Fix fixed array of map.\n- Fix stringification of usize struct fields (before, they were treated as 32 bit *signed* numbers).\n\n#### Comptime\n\n- A new `$res` comptime function to get returned value in defer block (#18382).\n- Fix comptimeselector option propagation.\n- A mutability check for comptime assignments.\n- Fix comptime assigning to sumtype or indexexpr.\n- Make comptime calls work with or-block.\n\n#### Tools\n\n- A new VPM site: vpm.vlang.io.

Works just like LDFLAGS in C.\n\n#### ORM\n\n- All ORM queries now return `![]` (`Result` of an array).\n This allows handling/propagating DB errors and simplifies working with ORM (one way).\n- Many ORM improvements: type checks for `limit/offset/order by/where`; support of reference objects\n in `insert`; struct fields can be used with `limit/offset`; `Connection` interface.\n- ORM now supports the `like` operator:\n ```v syntax-ok\n users := sql db {\n select from User where name like 'Bob%'\n }\n ```\n- A new `-d trace_orm` option to see all SQL queries generated and used by V ORM and\n `-d trace_pg_error` to trace PG errors.\n\n#### Standard Library\n\n- Added new `termios` module.\n- `net.ssl`: types using ssl contexts can now be converted to strings via `.str()`/printed\n via `println()`.\n- `v.reflection`: added type symbol info metadata.\n- `crypto` and `math` modules have been updated to use `Result` instead of `Option`.\n- `datatypes.LinkedList[map]` now works correctly.\n- `urllib.Values.get()` now returns an Option.\n- `strconv`: `v_printf()` was made private, `v_sprintf()` was deprecated. String interpolation\n should be used instead.\n- `net.http`: mime types have been updated to include all official types.\n- `gg`: `create_image()` now returns `!Image` instead of `Image`, allowing to handle errors.\n- `sokol`: errors during image creation no longer result in a panic, but can be handled by the\n programmer.\n- `sokol`: macOS apps can now be quit using **Cmd+Q**.\n- `os.hostname()` and `os.loginname()` now return `Result`.\n- `strconv.atoi` optimizations.\n- `println()` now supports arrays with recursive references.\n- `termux`: support for cross-compilation from termux to other platforms.\n- `readline` module now works much better on macOS: key navigation, history, etc (now on par with\n Linux).\n- `os`: fixed a memleak in `getline()`.\n- `os.Process` now has a `create_no_window` option (Windows only).\n- `os.Process` now has a `set_work_folder()` method to set the initial working folder of the new\n child process.\n\n#### Option as a first class type\n\nFinal steps in making the Option type a first class type:\n\n- If guards now work with struct fields which are `Option` functions.\n Such fields can now also be assigned to other fields/variables.\n- Option receivers can no longer have methods.\n- `none` can now be cast to all `Option` types, including aliases.\n- Option references are now supported: `?&Type`.\n- Arrays of `Option`s are now allowed.\n- Allow `foo := Foo{}`, when `Foo` has an Option field, that is a struct, that has a `[required]`\n tag on its fields.\n\n#### Compile-time Reflection\n\n- Compile-time interface fields evaluation.\n- Compile-time enum evaluation:\n ```v syntax-ok\n $for item in MyEnum.fields {\n println(item.value)\n println(item.name)\n }\n ```\n- Added `$option` as a compile-time reflection type representing an any Option type.\n- All special compile-time reflection types are now lowercase (`$int`, `$enum`, `$option`, etc).\n\n#### Checker Improvements/Fixes\n\n- Enums can no longer be initialized like structs.\n- Capture variables can no longer shadow anonymous function params.\n- Mixing multi-return results with other types in return statements is no longer allowed.\n- Assigning anonymous structs to named structs is no longer allowed.\n- `[required]` fields are now checked for embedded structs.\n- Fixed a bug with closures with fixed array variables.\n- Builtin methods `first/last/repeat` can now be used in custom user types (previously they only\n worked in builtin arrays).\n- Generic struct initialization no longer needs explicit types to be provided:\n ```v syntax-ok\n struct Foo[T, U] {\n \ta T\n \tb U\n }\n\n foo := Foo{\n \ta: 2\n \tb: 'x'\n }\n\n println(foo)\n ```\n- unsafe: dereferencing nil references is no longer allowed in the following case:\n ```v syntax-ok\n a := unsafe { nil }\n println(*a)\n ```\n\n#### OSes\n\n- Added basic QNX support.\n\n#### Other changes\n\n- Lots of documentation/readme improvements.\n- Lots of playground improvements: [play.vlang.io](https://play.vlang.io), including a really cool\n feature: \"Show generated C code\".\n- A new `[spawn_stack: 131072]` function attribute for controlling the max size of the stack of the\n spawned threads.\n- Channel pop now works with an `or` block: `ch := <-self.item or { return none }`\n- `it` has been renamed to `index` in array inits.\n- \"Is V still fast?\" web-page has been sped up by splitting the result table into multiple years.\n\n#### Development\n\n- GitHub Copilot summaries in PRs.\n\n## V 0.3.3\n\n*30 Jan 2023*\n\n#### Improvements in the language\n\n- String interpolation simplified to just '${name}', enforced by vfmt, and updated in the entire\n code base.\n- `go foo()` has been replaced with `spawn foo()` (launches an OS thread, `go` will be used for\n upcoming coroutines instead).\n- vfmt now supports `// vfmt off` and `// vfmt on` for turning off the formatting locally for short\n snippets of code.\n Useful for keeping your carefully arranged matrices intact.\n- Match branch range expressions with consts: `match x { const1...const2 {} }`\n- Hot code reloading via `[live]` is now supported in imported modules, not just the main module.\n- Syntax sugar for map inits without needing explicit casts for interfaces:\n `all.children := { \"abc\": rect, \"def\": ui.rectangle()}`.\n- `$embed_file()` fixes, including variable args support.\n- `none` fixes: no longer allowed to be used as a separate type, `dump()` support, not allowed\n inside `unsafe`.\n- Const functions: `const y = term.yellow`, then `println(y('abc'))`.\n- Builtin type names can no longer be used as identifiers.\n- Generic `typeof[T]()`, `sizeof[T]()`, `isreftype[T]()` functions.\n- Deprecated `-error-limit` in favour of the documented `-message-limit` option.\n- Maps now support aliased keys.\n- Operator overloading now works with reference types.\n- Generic struct inits with nested generic structs and generic optional types are now allowed.\n- During array creation, `len:` is required when using default values for the array.\n- Optimized one byte `[]u8` arrays creation.\n- Recursive aliasing is no longer allowed (e.g. `type Alias = map[string]Alias`).\n\n#### Breaking changes\n\n- `[]` is now used for generics instead of `<>`.\n- Accessing a pointer map value requires an `or {}` block outside `unsafe`.\n\n#### Checker improvements/fixes\n\n- Lots of fixes in the type checker.\n- Int signedness mismatch is now checked: `cannot use literal signed integer as u8`.\n\n#### Standard library\n\n- `math.vec` module for generic vector math including 2D, 3D, and 4D vector operations.\n- Builtin stb_image.h used by gg has been updated to the latest v2.28.\n- All of vlib has been updated to use separate Option/Result types.\n- To avoid confusion, all references in the code and documentation to `Optional` have been replaced\n with `Option`.\n- `gg.Context` pipeline has more effects, including the `additive` effect.\n- Much cleaner eof checks in `os`: refactor `err == IError(os.Eof{})` to `err is os.Eof`.\n- Lots of work on `x.json2`, the pure V json encoder, soon to become official.\n- New `v.reflection` module for runtime reflection.\n- Improved `os.mv()`, which now works consistently even across different windows drives/mount\n points.\n- `string.trim_indent()`, useful with multi line strings, that start/end with new lines and\n indentation.\n- Reduced memory consumption in the `crypto` modules.\n- Official V UI library is now licensed under MIT.\n- Deprecated `math.util` and

interpolation support, type checks, fn calls\n in `where`.\n\n#### Database drivers\n\n- VFS support in the builtin `sqlite` module; `sqlite.get_affected_rows_count()`.\n- Improved `pg` compatibility with older PostgreSQL versions before 2014.\n- `sqlite`, `pg`, `mysql` have been moved to `db.sqlite`, `db.pg`, `db.mysql`.\n\n#### Native backend\n\n- Operator support for floats, multi

Work on [V RFCs](https://github.com/vlang/rfcs/) (submitting new ones,\n providing feedback to existing ones, implementing them).\n\n## Code Structure\n\nI tried to make the code of the compiler and vlib as simple and readable as\npossible. One of V's goals is to be open to developers with different levels\nof experience in compiler development. Compilers don't need to be black boxes\nfull of magic that only few people understand.\n\nThe V compiler is modular, and can be used by other applications. It is located\nin `cmd/v/` and `vlib/v/`.\n\nThe most important and useful command to remember when working on the V compiler\nis `v self`.\nIt rebuilds the V compiler.\n\nBe careful, if you introduce a breaking change and rebuild V, you will no longer\nbe able to use V to build itself. So it's a good idea to make a backup copy of a\nworking compiler executable.\n\nBut don't worry, you can always simply run `make` (or `make.bat`), it will\ndownload the C version of the compiler and rebuild it from scratch.\n\nThe architecture of the compiler is very simple and has three distinct steps:\n\nParse/generate AST (`v.parser`) => Check types (`v.checker`)\n=> Generate C/JavaScript/machine code (`v.gen`)\n\nThe main files are:\n\n1. `cmd/v/v.v` The entry point.\n\n - V figures out the build mode.\n - Constructs the compiler object (`struct V`).\n - Creates a list of .v files that need to be parsed.\n - Creates a parser object for each file and runs `parse()` on them.\n - The correct backend is called (C, JS, native), and a binary is compiled.\n\n2. `vlib/v/scanner` The scanner's job is to parse a list of characters and convert\n them to tokens.\n\n3. `vlib/v/token` This is simply a list of all tokens, their string values, and a\n couple of helper functions.\n\n4. `vlib/v/parser` The parser. It converts a list of tokens into an AST.\n In V, objects can be used before declaration, so unknown types are marked as\n unresolved. They are resolved later in the type checker.\n\n5. `vlib/v/table` V creates one table object that is shared by all parsers. It\n contains all types, consts, and functions, as well as several helpers to search\n for objects by name, register new objects, modify types' fields, etc.\n\n6. `vlib/v/checker` Type checker and resolver. It processes the AST and makes sure\n the types are correct. Unresolved types are resolved, type information is added\n to the AST.\n\n7. `vlib/v/gen/c` C backend. It simply walks the AST and generates C code that can be\n compiled with Clang, GCC, Visual Studio, and TCC.\n\n8. `vlib/v/gen/js` JavaScript backend. It simply walks the AST and generates JS code that can be\n executed on the browser or in NodeJS/Deno.\n\n9. `vlib/v/gen/c/json.v` defines the json code generation. This file will be removed once V\n supports comptime code generation, and it will be possible to do this using the\n language's tools.\n\n10. `vlib/v/gen/native` is the directory with all the machine code generation logic. It\n defines a set of functions that translate assembly instructions to machine code\n and build the binary from scratch byte by byte. It manually builds all headers,\n segments, sections, symtable, relocations, etc. Right now it only has basic\n support of the native platform (ELF, MACHO format).\n\nThe rest of the directories are vlib modules: `builtin/` (strings, arrays,\nmaps), `time/`, `os/`, etc. Their documentation is pretty clear.\n\n## Example Workflow for Contributing\n\n(provided by [@spytheman](https://github.com/spytheman))\n\n(If you don't already have a GitHub account, please create one. Your GitHub\nusername will be referred to later as 'YOUR_GITHUB_USERNAME'. Change it\naccordingly in the steps below.)\n\n1. Fork https://github.com/vlang/v using GitHub's interface to your own account.\n Let's say that the forked repository is at\n `https://github.com/YOUR_GITHUB_USERNAME/v` .\n2. Clone the main v repository https://github.com/vlang/v to a local folder on\n your computer, say named nv/ (`git clone --depth=1 https://github.com/vlang/v nv`)\n3. `cd nv`\n 3.1 (optional) Run these commands, which ensure that all your code will be\n automatically formatted, before committing:\n ```\n cp cmd/tools/git_pre_commit_hook.vsh .git/hooks/pre-commit\n chmod 755 .git/hooks/pre-commit\n ```\n It has to be done in a shell where you have done cd /root/of/your/V_repo once.\n Step 3 above does it with `cd nv`.\n I.e. you have to be in the top level folder, that contains the .git folder for the V repository.\n \n4. `git remote add pullrequest https://github.com/YOUR_GITHUB_USERNAME/v`\n\n Note: The remote named `pullrequest` should point to YOUR own forked repo, not the\n main v repository! After this, your local cloned repository is prepared for\n making pull requests, and you can just do normal git operations such as:\n `git pull` `git status` and so on.\n\n5. When finished with a feature/bugfix/change, you can:\n `git checkout -b fix_alabala`\n - Don't forget to keep formatting standards, run `v fmt -w YOUR_MODIFIED_FILES`\n before committing (if you have not run the commands from 3.1)\n - If you changed Markdown (`.md`) files, check them `v check-md YOUR_MODIFIED_FILES`\n before committing.\n6. `git push pullrequest` Note: The `pullrequest` remote was setup on step 4\n\n7. On GitHub's web interface, go to: https://github.com/vlang/v/pulls\n\n Here the UI shows a dialog with a button to make a new pull request based on\n the new pushed branch.\n (Example dialog: https://url4e.com/gyazo/images/364edc04.png)\n\n8. After making your pull request (aka, PR), you can continue to work on the\n branch `fix_alabala` ... just do again `git push pullrequest` when you have more\n commits.\n\n9. If there are merge conflicts, or a branch lags too much behind V's master,\n you can do the following:\n\n 1. `git pull --rebase origin master` # solve conflicts and do\n `git rebase --continue`\n 2. `git push pullrequest -f` # this will overwrite your current remote branch\n with the updated version of your changes.\n\nThe point of doing the above steps, is to never directly push to the main V\nrepository, *only to your own fork*. Since your local `master` branch tracks the\nmain V repository's master, then `git checkout master`, as well as\n`git pull --rebase origin master` will continue to work as expected\n(these are actually used by `v up`) and git can always do it cleanly.\n\nGit is very flexible, so there are other ways to accomplish the same thing.\nSee the [GitHub flow](https://guides.github.com/introduction/git-handbook/#github), for more\ninformation.\n\n## Finding issues to contribute to\n\nIf you're willing to contribute to V but don't know which issue to resolve\n\n- you can go to [Issues](https://github.com/vlang/v/issues) tab\n in this repository. There you can see things logged by both users and developers\n that need to be discussed and/or resolved.\n\nIt's recommended to filter issues by likes and labels to find an issue\nyou are interested in.\n\n### Filtering by likes (recommended)\n\nFiltering by likes helps you identify high-impact issues.\nMore likes mean more community interest.\n\nTo quickly use this filter, click [there](https://github.com/vlang/v/issues?q=is%3Aopen+is%3Aissue+sort%3Areactions-%2B1-desc).\n\nTo manually apply this filter, navigate to [Issues](https://github.com/vlang/v/issues)\ntab, then paste the following in the \"Filter\" field:\n\n```\nis:open is:issue sort:reactions-+1-desc\n```\n\nThis filter will return all open issues sorted by likes in descending order.\n\n### Filtering by labels\n\nThe V repo has various labels to help navigate the extensive list of issues\nand help you find issues you're both interested in and capable of resolving.\nYou can examine the list of labels [here](https://github.com/vlang/v/labels).\n\nThe most common labels are:\n\nBy issue type:\n\n- `Bug`\n- `Feature Request`\n\nBy OS:\n\n- `OS: Linux`\n- `OS: Windows`\n- `OS: Mac`\n\nBy status:\n\n- `Status: Confirmed`\n\nTo apply this filter, navigate to [Issues](https://github.com/vlang/v/issues)\ntab, then paste the following in the \"Filter\" field:\n\n```\nis:open is:issue label:Bug label:\"OS: Windows\" label:\"Status: Confirmed\"\n```\n\nThis filter will return all open issues with the labels `Bug`, `OS: Windows`,\nand `Status: Confirmed`.\n\n## Using Github's hub CLI tool\n\nYou can download the `hub` tool from https://hub.github.com/ . Using\n`hub`, you will not need to go through the (sometimes) slow website\nto make PRs. Most remote operations can be done through the `hub` CLI\ncommand.\n\n> [!NOTE]\n> You still need to have a GitHub account.\n\n### Preparation:\n\n(steps 1..3 need to be done just *once*):\n\n1. `hub clone vlang/v my_v`\n2. `cd my_v`\n 2.1 (optional) Run these commands, which ensure that all your code will be\n automatically formatted, before committing:\n ```\n cp cmd/tools/git_pre_commit_hook.vsh .git/hooks/pre-commit\n chmod 755 .git/hooks/pre-commit\n ```\n3. `hub fork --remote-name pullrequest`\n\n4. `git checkout -b my_cool_feature` # Step 4 is better done *once per each new\n feature/bugfix* that you make.\n\n### Improve V by making commits:\n\n5. `git commit -am \"math: add a new function copysign\"`\n\n### Testing your commits locally:\n\nYou can test locally whether your changes have not broken something by\nrunning: `v test-all`. See `TESTS.md` for more details.\n\n### Publishing your commits to GitHub:\n\n6. `git push pullrequest`\n\n### Making a PR with `hub`:\n\n(so that your changes can be merged to the main V repository)\n\n7. `hub pull-request`\n\nOptionally, you can track the status of your PR CI tests with:\n\n8. `hub ci-status --verbose`\n\n### Fixing failing tests:\n\nIf everything is OK, after 5-10 minutes, the CI tests should pass for\nall platforms. If not, visit the URLs for the failing CI jobs, see\nwhich tests have failed and then fix them by making more changes. Just use\n`git push pullrequest` to publish your changes. The CI tests will\nrun with your updated code. Use `hub ci-status --verbose` to monitor\ntheir status.\n\n## Compiler flags, useful while debugging the compiler itself:\n\nV allows you to pass custom flags using `-d my_flag` that can then be checked\nat compile time (see the documentation about\n[compile-time if](https://github.com/vlang/v/blob/master/doc/docs.md#compile-time-if)).\n\nSince the compiler is *also* an ordinary V program, there are numerous flags that can be\npassed when building the compiler itself with `v self`, or when creating a copy of the\ncompiler, that will help you when debugging the compiler.\n\nNote: beware that the flags below must be passed, when building the compiler, *not the program*,\nso do for example:\n`./v -o w -d time_parsing cmd/v`\nor\n`./v -o w -d trace_checker self`\n... then use `./w file.v`, instead of `./v file.v`, to compile your program.\n\nNote: some of the flags can make the compiler *very verbose*, so it is recommended to create\na copy of the compiler rather than replacing it with `v self`.\n\n| Flag | Usage |\n|-----------------------------------|---------------------------------------------------------------------------------------------------------------------|\n| `debug_codegen` | Prints automatically generated V code during the scanning phase |\n| `debug_interface_table` | Prints generated interfaces during C generation |\n| `debug_interface_type_implements` | Prints debug information when checking that a type implements in interface |\n| `print_vweb_template_expansions` | Prints vweb compiled HTML files |\n| `time_checking` | Prints the time spent checking files and other related information |\n| `time_parsing` | Prints the time spent parsing files and other related information |\n| | |\n| `trace_scanner` | Prints details about the recognized tokens. *Very* verbose.

Use it to diagnose cgen order issues. |\n| `trace_cgen_stmt` | Prints details about the statements that are being processed by cgen. |\n| | Use it for panics in cgen, to see the closest input V source line, that caused the panic. |\n| | Note: you need `v -no-parallel -d trace_cgen_stmt -o w cmd/v` to make sense of the output of that, |\n| | otherwise by default cgen uses several threads, and the

\n\n## Key Features of V\n\n- Simplicity: the language can be learned over the course of a weekend\n- Fast compilation: ≈110k loc/s with a Clang backend,\n ≈500k loc/s with native and tcc backends *(Intel i5-7500, SSD, no\n optimization)* ([demo video](https://www.youtube.com/watch?v=pvP6wmcl_Sc))\n- Easy to develop: V compiles itself in less than a second\n- Performance: as fast as C (V's main backend compiles to human-readable C)\n- Safety: no null, no globals, no undefined behavior (wip), immutability by default\n- C to V translation ([Translating DOOM demo video](https://www.youtube.com/watch?v=6oXrz3oRoEg))\n- Hot code reloading\n- [Flexible memory management](https://vlang.io/#memory). GC by default, manual via `v -gc none`,\n arena allocation via `v -prealloc`, autofree via `v -autofree`\n ([autofree demo video](https://www.youtube.com/watch?v=gmB8ea8uLsM)).\n- [Cross-platform UI library](https://github.com/vlang/ui)\n- Built-in graphics library\n- Easy cross-compilation\n- REPL\n- [Built-in ORM](https://github.com/vlang/v/blob/master/doc/docs.md#orm)\n- [Built-in web framework](https://github.com/vlang/v/blob/master/vlib/veb/README.md)\n- C and JavaScript backends\n- Great for writing low-level software ([Vinix OS](https://github.com/vlang/vinix))\n\n## Stability, future changes, post 1.0 freeze\n\nDespite being at an early development stage, the V language is relatively stable, and doesn't\nchange often. But there will be changes before 1.0.\nMost changes in the syntax are handled via vfmt automatically.\n\nThe V core APIs (primarily the `os` module) will also have minor changes until\nthey are stabilized in V 1.0. Of course, the APIs will grow after that, but without breaking\nexisting code.\n\nAfter the 1.0 release V is going to be in the \"feature freeze\" mode. That means no breaking changes\nin the language, only bug fixes and performance improvements. Similar to Go.\n\nWill there be V 2.0? Not within a decade after 1.0, perhaps not ever.\n\nTo sum it up, unlike many other languages, V is not going to be always changing, with new features\nintroduced and old features modified. It is always going to be a small and simple\nlanguage, very similar to the way it is right now.\n\n## Installing V from source\n\n**This is the preferred method.**\n\n### Linux, macOS, Windows, \\*BSD, Solaris, WSL, etc.\n\nUsually, installing V is quite simple if you have an environment that already has a\nfunctional `git` installation.\n\nNote: On Windows, run `make.bat` instead of `make` in CMD, or `./make.bat` in PowerShell.\nNote: On Ubuntu/Debian, you may need to run `sudo apt install git build-essential make` first.\n\nTo get started, execute the following in your terminal/shell:\n```bash\ngit clone --depth=1 https://github.com/vlang/v\ncd v\nmake\n```\n\nThat should be it, and you should find your V executable at `[path to V repo]/v`.\n`[path to V repo]` can be anywhere.\n\n(Like the note above says, on Windows, use `make.bat`, instead of `make`.)\n\nNow try running `./v run examples/hello_world.v` (or `v run examples/hello_world.v` in cmd shell).\n\n- *Trouble? Please see the notes above, and link to\n [Installation Issues](https://github.com/vlang/v/discussions/categories/installation-issues)\n for help.*\n\nNote: V is being constantly updated. To update V to its latest version, simply run:\n\n```bash\nv up\n```\n\n> [!NOTE]\n> If you run into any trouble, or you have a different operating\n> system or Linux distribution that doesn't install or work immediately, please see\n> [Installation Issues](https://github.com/vlang/v/discussions/categories/installation-issues)\n> and search for your OS and problem.\n>\n> If you can't find your problem, please add it to an existing discussion if one exists for\n> your OS, or create a new one if a main discussion doesn't yet exist for your OS.\n\n### Void Linux\n\n```bash\n# xbps-install -Su base-devel\n# xbps-install libatomic-devel\n$ git clone --depth=1 https://github.com/vlang/v\n$ cd v\n$ make\n```\n\n### Docker\n\n```bash\ngit clone --depth=1 https://github.com/vlang/v\ncd v\ndocker build -t vlang .\ndocker run --rm -it vlang:latest\n```\n\n### Docker with Alpine/musl\n\n```bash\ngit clone --depth=1 https://github.com/vlang/v\ncd v\ndocker build -t vlang_alpine - < Dockerfile.alpine\nalias with_alpine='docker run -u 1000:1000 --rm -it -v .:/src -w /src vlang_alpine:latest'\n```\n\nCompiling *static* executables, ready to be copied to a server, that is running\nanother linux distro, without dependencies:\n```bash\nwith_alpine v -skip-unused -prod -cc gcc -cflags -static -compress examples/http_server.v\nwith_alpine v -skip-unused -prod -cc gcc -cflags -static -compress -gc none examples/hello_world.v\nls -la examples/http_server examples/hello_world\nfile examples/http_server examples/hello_world\nexamples/http_server: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, no section header\nexamples/hello_world: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, no section header\n```\n\nYou should see something like this:\n```\n-rwxr-xr-x 1 root root 16612 May 27 17:07 examples/hello_world\n-rwxr-xr-x 1 root root 335308 May 27 17:07 examples/http_server\n```\n\n### FreeBSD\n\nOn FreeBSD, V needs `boehm-gc-threaded` package preinstalled. After installing it, you can use the\nsame script, like on Linux/macos:\n\n```bash\npkg install boehm-gc-threaded\ngit clone --depth=1 https://github.com/vlang/v\ncd v\nmake\n```\n\n### OpenBSD\n\nOn OpenBSD (release 7.8), V needs `boehm-gc` and `openssl-3.5` packages preinstalled. After\ninstalling them, use GNU `make` (installed with `gmake` package), to build V.\n\n```bash\npkg_add boehm-gc openssl%3.5 gmake\ngit clone --depth=1 https://github.com/vlang/v\ncd v\ngmake\n```\n\n### Termux/Android\n\nOn Termux, V needs some packages preinstalled - a working C compiler, also `libexecinfo`,\n`libgc` and `libgc-static`. After installing them, you can use the same script, like on\nLinux/macos:\n\n```bash\npkg install clang libexecinfo libgc libgc-static make git\npkg update\ngit clone --depth=1 https://github.com/vlang/v\ncd v\nmake\n./v symlink\n```\nNote: there is *no* need for `sudo ./v symlink` on Termux (and sudo is not installed by default).\n\n### C compiler\n\nThe [Tiny C Compiler (tcc)](https://repo.or.cz/w/tinycc.git) is downloaded for you by `make` if\nthere is a compatible version for your system, and installed under the V `thirdparty` directory.\n\nThis compiler is very fast, but does almost no optimizations. It is best for development builds.\n\nFor production builds (using the `-prod` option to V), it's recommended to use clang, gcc, or\nMicrosoft Visual C++. If you are doing development, you most likely already have one of those\ninstalled.\n\nOtherwise, follow these instructions:\n\n- [Installing a C compiler on Linux and macOS](https://github.com/vlang/v/wiki/Installing-a-C-compiler-on-Linux-and-macOS)\n\n- [Installing a C compiler on Windows](https://github.com/vlang/v/wiki/Installing-a-C-compiler-on-Windows)\n\n### Symlinking\n\n> [!NOTE]\n> It is *highly recommended*, that you put V on your PATH. That saves\n> you the effort to type in the full path to your v executable every time.\n> V provides a convenience `v symlink` command to do that more easily.\n\nOn Unix systems, it creates a `/usr/local/bin/v` symlink to your\nexecutable. To do that, run:\n\n```bash\nsudo ./v symlink\n```\n\nOn Windows, start a new shell with administrative privileges, for example by pressing the\nWindows Key, then type `cmd.exe`, right-click on its menu entry, and choose `Run as\nadministrator`. In the new administrative shell, cd to the path where you have compiled V, then\ntype:\n\n```bat\nv symlink\n```\n\n(or `.\\v symlink` in PowerShell)\n\nThat will make V available everywhere, by adding it to your PATH. Please restart your\nshell/editor after that, so that it can pick up the new PATH variable.\n\n> [!NOTE]\n> There is no need to run `v symlink` more than once - v will still be available, even after\n> `v up`, restarts, and so on. You only need to run it again if you decide to move the V repo\n> folder somewhere else.\n\n## Editor/IDE Plugins\n\n- [Atom](https://github.com/vlang/awesome-v#atom)\n- [Emacs](https://github.com/vlang/awesome-v#emacs)\n- [JetBrains](https://plugins.jetbrains.com/plugin/20287-vlang/docs/syntax-highlighting.html)\n- [Sublime Text 3](https://github.com/vlang/awesome-v#sublime-text-3)\n- [Vim](https://github.com/vlang/awesome-v#vim)\n- [Vim/Neovim Runtime Files](editors/vim)\n- [VS Code](https://marketplace.visualstudio.com/items?itemName=VOSCA.vscode-v-analyzer)\n- [zed](https://github.com/lv37/zed-v)\n\n\nTo bring IDE functions for the V programming languages to your editor, check out\n[v-analyzer](https://github.com/vlang/v-analyzer).

Pass `-gc ` if you need a different GC mode.\n\n```bash\ncd examples\nv hello_world.v && ./hello_world # or simply\nv run hello_world.v # this builds the program and runs it right away\n\nv run word_counter/word_counter.v word_counter/cinderella.txt\nv run news_fetcher.v\nv run tetris/tetris.v\n```\n\nWhen a project has a `.vvmrc` file, `v ` and `v run ` try\nto use the requested V binary (for example `v0.4.6`) before falling back to\nthe current compiler.\n\n\ntetris screenshot\n\n## Sokol and GG GUI apps/games:\n\nIn order to build Tetris or 2048 (or anything else using the `sokol` or `gg` graphics modules),\nyou will need to install additional development libraries for your system.\n\n| System | Installation method |\n|---------------------|----------------------------------------------------------------------------------------------------|\n| Debian/Ubuntu based | Run `sudo apt install libxi-dev libxcursor-dev libgl-dev libxrandr-dev libasound2-dev` |\n| Fedora/RH/CentOS | Run `sudo dnf install libXi-devel libXcursor-devel libX11-devel libXrandr-devel libglvnd-devel` |\n| | |\n| NixOS | Add `xorg.libX11.dev xorg.libXcursor.dev xorg.libXi.dev xorg.libXrandr.dev libGL.dev` to |\n| | to `environment.systemPackages` |\n\n## V net.http, net.websocket, `v install`\n\nThe net.http module, the net.websocket module, and the `v install` command may all use SSL.\nV comes with a version of mbedtls, which should work on all systems. If you find a need to\nuse OpenSSL instead, you will need to make sure that it is installed on your system, then\nuse the `-d use_openssl` switch when you compile.\n\nNote: Mbed-TLS is smaller and easier to install on windows too (V comes with it), but if you\nwrite programs, that do lots of http requests to HTTPS/SSL servers, in most cases, it is *best*\nto compile with `-d use_openssl`, and do so on a system, where you do have OpenSSL installed\n(see below). Mbed-TLS is slower, and can have more issues, especially when you are doing parallel\nhttp requests to multiple hosts (for example in web scrapers, REST API clients, RSS readers, etc).\nOn windows, it is better to run such programs in WSL2.\n\nTo install OpenSSL on non-Windows systems:\n\n| System | Installation command |\n|---------------------|----------------------------------|\n| macOS | `brew install openssl` |\n| Debian/Ubuntu based | `sudo apt install libssl-dev` |\n| Arch/Manjaro | openssl is installed by default |\n| Fedora/CentOS/RH | `sudo dnf install openssl-devel` |\n\nOn Windows, OpenSSL is simply hard to get working correctly. The instructions\n[here](https://tecadmin.net/install-openssl-on-windows/) may (or may not) help.\n\n## V sync\n\nV's `sync` module and channel implementation uses libatomic.\nIt is most likely already installed on your system, but if not,\nyou can install it, by doing the following:\n\n| System | Installation command |\n|---------------------|-------------------------------------|\n| macOS | already installed |\n| Debian/Ubuntu based | `sudo apt install libatomic1` |\n| Fedora/CentOS/RH | `sudo dnf install libatomic-static` |\n\n## V UI\n\n\nV UI example screenshot\n\n\nhttps://github.com/vlang/ui\n\n\n\n## Android graphical apps\n\nWith V's `vab` tool, building V UI and graphical apps for Android can become as easy as:\n\n```\n./vab /path/to/v/examples/2048\n```\n\n[https://github.com/vlang/vab](https://github.com/vlang/vab).\n\"vab\n\n## Developing web applications\n\nCheck out the\n[Building a simple web blog](https://github.com/vlang/v/blob/master/tutorials/building_a_simple_web_blog_with_veb/README.md)\ntutorial and Gitly, a light and fast alternative to GitHub/GitLab:\n\nhttps://github.com/vlang/gitly\n\n\"gitly\n\n## Vinix, an OS/kernel written in V\n\nV is great for writing low-level software like drivers and kernels.\nVinix is an OS/kernel that already runs bash, GCC, V, and nano.\n\nhttps://github.com/vlang/vinix\n\n\"vinix\n\"vinix\n\n## Acknowledgement\n\n### TCC\n\nV thanks Fabrice Bellard for his original work on the\n[TCC - Tiny C Compiler](https://bellard.org/tcc/).\nNote the TCC website is old; the current TCC repository can be found\n[here](https://repo.or.cz/w/tinycc.git).\nV utilizes pre-built TCC binaries located at\n[https://github.com/vlang/tccbin/](https://github.com/vlang/tccbin/).\n\n### PVS-Studio\n\n[PVS-Studio](https://pvs-studio.com/pvs-studio/?utm_source=website&utm_medium=github&utm_campaign=open_source) - static analyzer for C, C++, C#, and Java code.\n\n## Troubleshooting\n\nPlease see the\n[Troubleshooting](https://github.com/vlang/v/wiki/Troubleshooting)\nsection on our\n[wiki page](https://github.com/vlang/v/wiki).\n\n[WorkflowBadge]: https://github.com/vlang/v/workflows/CI/badge.svg\n[DiscordBadge]: https://img.shields.io/discord/592103645835821068?label=Discord&logo=discord&logoColor=white\n[PatreonBadge]: https://img.shields.io/endpoint.svg?url=https%3A%2F%2Fshieldsio-patreon.vercel.app%2Fapi%3Fusername%3Dvlang%26type%3Dpatrons&style=flat\n[SponsorBadge]: https://img.shields.io/github/sponsors/medvednikov?style=flat&logo=github&logoColor=white\n[XBadge]: https://img.shields.io/badge/follow-%40v__language-1DA1F2?logo=x&style=flat&logoColor=white\n[ModulesBadge]: https://img.shields.io/badge/modules-reference-027d9c?logo=v&logoColor=white&logoWidth=10\n\n[WorkflowUrl]: https://github.com/vlang/v/commits/master\n[DiscordUrl]: https://discord.gg/vlang\n[PatreonUrl]: https://patreon.com/vlang\n[SponsorUrl]: https://github.com/sponsors/medvednikov\n[XUrl]: https://x.com/v_language\n[ModulesUrl]: https://modules.vlang.io\n" }, { "path": "ROADMAP.md", "content": "Roadmap with big features.\nFor a list of all features and fixes, check out the changelog.\n\n## [Version 0.3]\n\n- [x] gc option\n- [x] channels\n- [x] lock{}\n- [x] thread safe arrays\n- [x] rune type\n- [x] replace `ustring` with `[]rune`\n- [x] fix `byte.str()`\n- [x] maps with non-string keys\n- [x] iOS/Android support\n- [x] parallel cgen\n- [x] IO streams\n- [x] struct embedding\n- [x] interface embedding\n- [x] interfaces: allow struct fields (not just methods)\n- [x] short generics syntax (`foo(5)` instead of `foo(5)`)\n- [x] more advanced errors, not just `error('message')`\n\n## [Version 0.4]\n\n- [x] [Coroutines](https://github.com/vlang/v/discussions/11582) (doesn't work on Windows yet)\n- [x] vfmt: add missing imports (like goimports)\n- [x] Recursive structs via options: `struct Node { next ?Node }`\n- [x] First class Option type\n- [x] Optional function struct fields\n- [x] Handle function pointers safely, remove `if function == 0 {`\n- [x] Bundle an SSL library (mbedtls) like GC\n- [x] Anonymous structs\n- [x] Improve vweb: allow separation of logic via \"controllers\", lots of other fixes\n- [x] New VPM site\n\n## [Version 0.5]\n\n- [x] Parallel C compilation via `-parallel-cc`\n- [x] Parallel parser (not integrated yet)\n- [x] Parallel checker (not integrated yet)\n- [x] Improved vweb => veb framework.

Most test commands\nwill use the V compiler and the V tools many times, potentially\nhundreds/thousands of times.\n\n## `v test-all`\n\nTest and build *everything*. Useful to verify *locally*, that the CI will\nmost likely pass. Slowest, but most comprehensive.\n\nIt works, by running these in succession:\n\n* `v test-cleancode`\n* `v test-self`\n* `v test-fmt`\n* `v build-tools`\n* `v build-examples`\n* `v check-md -hide-warnings .`\n* `v install nedpals.args`\n\n# Details:\n\nIn the `v` repo there are many tests. The main types are:\n\n## `_test.v` tests - these are the normal V test files.\n\nAll `test_` functions in these files, will be ran automatically by\nV's test framework.\n\nNB 1: You can run test files one by one, with:\n`v file_test.v` - this will run the test_ functions in file_test.v,\nand will exit with a 0 exit code, if they all had 0 failing assertions.\n\n`v -stats file_test.v` - this will run the test_ functions, and show a\nreport about how much time it took to run each of them too.\n\nNB 2: You can also run many test files at once (in parallel, depending on\nhow many cores you have), with:\n`v test folder` - this will run *all* `_test.v` files in `folder`,\nrecursively.\n\n`v -stats test folder` - same, but will also produce timing reports\nabout how fast each test_ function in each _test.v file ran.\n\n## `v test vlib/v/tests`:\n\nThis folder contains _test.v files, testing the different features of the V\ncompiler. Each of them will be compiled, and all the features in them have\nto work (verified by assertions).\n\n## `v vlib/v/slow_tests/inout/compiler_test.v`\n\nThis is a *test runner*, that checks whether the output of running a V program,\nmatches an expected .out file. You can also check for code that does panic\nusing this test runner - just paste the start of the `panic()` output in the\ncorresponding .out file.\n\n> [!NOTE]\n> These tests, expect to find a pair of `.vv` and `.out` files, in the folder:\n> vlib/v/slow_tests/inout\n\nThe test runner will run each `.vv` file, and will check that its output, matches\nthe contents of the `.out` file with the same base name. This is particularly useful\nfor checking that errors and panics are printed.\n\n## `v vlib/v/gen/c/coutput_test.v`\n\ncoutput_test.v is a *test runner*, that checks whether the generated C source\ncode matches *all* expectations, specified in *.c.must_have files, in the\nfolder vlib/v/gen/c/testdata/ .\n\nEach `.c.must_have` file, *has* to have a corresponding `.vv` file.\n\nEach `.c.must_have` file, consists of multiple lines. Each of these\nlines, *should* be present *at least once* in the output, when the .vv\nfile is compiled with `-o -` .\n\n## REPL tests\n\nThe test runner for these is `vlib/v/slow_tests/repl/repl_test.v`.\n\nThe test cases for the V REPL, are stored in .repl files, in the folder\n`vlib/v/slow_tests/repl/`. Each .repl file in this folder, contains several\nlines of input to the V repl, followed by a single line of `===output===`,\nand then the output lines, that the repl would normally show for the input\nlines.\n\nIf you change the compiler or the REPL source, and you have breaks in those\n.repl files, you can replace the current output in them, by running several\ntimes `VAUTOFIX=1 ./vlib/v/slow_tests/repl/repl_test.v`, until all the\nfiles are fixed and the test pass.\n\n## `v vlib/v/slow_tests/run_project_folders_test.v`\n\nThis *test runner*, checks whether whole project folders, can be compiled, and run.\n\n> [!NOTE]\n> Each project in these folders, should finish with an exit code of 0,\n> and it should output `OK` as its last stdout line.\n\n## `v vlib/v/tests/known_errors/known_errors_test.v`\n\nThis *test runner*, checks whether a known program, that was expected to compile,\nbut did NOT, due to a buggy checker, parser or cgen, continues to fail.\nThe negative programs are collected in the `vlib/v/tests/known_errors/testdata/` folder.\nEach of them should FAIL to compile, due to a known/confirmed compiler bug/limitation.\n\nThe intended use of this, is for providing samples, that currently do NOT compile,\nbut that a future compiler improvement WILL be able to compile, and to\ntrack, whether they were not fixed incidentally, due to an unrelated\nchange/improvement. For example, code that triggers generating invalid C code can go here,\nand later when a bug is fixed, can be moved to a proper _test.v or .vv/.out pair, outside of\nthe `vlib/v/tests/known_errors/testdata/` folder.\n\n## Test building of actual V programs (examples, tools, V itself)\n\n* `v build-tools`\n* `v build-examples`\n* `v build-vbinaries`\n\n## Formatting tests\n\nIn `vlib/v/fmt/` there are:\n\n* `v vlib/v/fmt/fmt_test.v`\n\nThis checks `.out` tests.\n\n* `v vlib/v/fmt/fmt_keep_test.v`\n\nThis verifies that all `_keep.vv` files in the `vlib/v/fmt/tests/` folder,\nwould be unchanged by `v fmt -w`, i.e. that the v source code formatter,\ngenerates a stable source output, that does not change, once it is already\nformatted once.\n\n* `v vlib/v/fmt/fmt_vlib_test.v`\n\nThis checks that all V source files are formatted, and prints a summary.\nThis is not required.\n\n* `v test-cleancode`\n\nCheck that most .v files, are invariant of `v fmt` runs.\n\n* `v test-fmt`\n\nThis tests that all .v files in the current folder are already formatted.\nIt is useful for adding to CI jobs, to guarantee, that future contributions\nwill keep the existing source nice and clean.\n\n## Markdown/documentation checks:\n\n* `v check-md -hide-warnings .`\n\nEnsure that all .md files in the project are formatted properly,\nand that the V code block examples in them can be compiled/formatted too.\n\nNote: if that command finds formatting errors, they can be fixed with:\n`VAUTOFIX=1 ./v check-md file.md` or with `v check-md -fix file.md`.\n\n## `v test-self`\n\nRun `vlib` module tests, *including* the compiler tests.\n\n## `v vlib/v/compiler_errors_test.v`\n\nThis runs tests for:\n\n* `vlib/v/scanner/tests/*.vv`\n* `vlib/v/checker/tests/*.vv`\n* `vlib/v/parser/tests/*.vv`\n\n> [!NOTE]\n> There are special folders, that compiler_errors_test.v will try to\n> run/compile with specific options:\n\nvlib/v/checker/tests/globals_run/ - `-enable-globals run`;\nresults stored in `.run.out` files, matching the .vv ones.\n\nNB 2: in case you need to modify many .out files, run *twice* in a row:\n`VAUTOFIX=1 ./v vlib/v/compiler_errors_test.v`\nThis will fail the first time, but it will record the new output for each\n.vv file, and store it into the corresponding .out file. The second run\nshould be now successful, and so you can inspect the difference, and\ncommit the new .out files with minimum manual effort.\n\nNB 3: To run only some of the tests, use:\n`VTEST_ONLY=mismatch ./v vlib/v/compiler_errors_test.v`\nThis will check only the .vv files, whose paths match the given filter.\n\nNB 4: To run tests, but without printing status lines for all the successfull\nones, use:\n`VTEST_HIDE_OK=1 ./v test vlib/math/`\nThis will print only the total stats, and the failing tests, but otherwise\nit will be silent. It is useful, when you have hundreds or thousands of\nindividual `_test.v` files, and you want to avoid scrolling.\n\nNB 5: To show only *the currently running test*, use:\n`./v -progress test vlib/math/`\nIn this mode, the output lines will be limited, no matter how many `_test.v`\nfiles there are. The output will contain the total stats and the output of\nthe failing tests too.\n\n## `.github/workflows/ci.yml`\n\nThis is a Github Actions configuration file, that runs various CI\ntests in the main V repository, for example:\n\n* `v vet vlib/v` - run a style checker.\n* `v test-self` (run self tests) in various compilation modes.\n\n> [!NOTE]\nThe VDOC test vdoc_file_test.v now also supports VAUTOFIX, which is\nuseful, if you change anything inside cmd/tools/vdoc,\nor inside the modules that it depends on (like markdown).\nAfter such changes, just run this command *2 times*, and commit the\nresulting changes in `cmd/tools/vdoc/testdata` as well:\n`VAUTOFIX=1 ./v cmd/tools/vdoc/vdoc_file_test.v`\n" }, { "path": "bench/README.md", "content": "### Vectors\n\n```bash\nBenchmark 1: ./boids_test/bin/Release/net7.0/linux-x64/publish/boids_test\nTime (mean ± σ): 262.2 ms ± 5.7 ms [User: 231.6 ms, System: 14.1 ms]\nRange (min … max): 255.4 ms … 275.3 ms 11 runs\n\nBenchmark 2: ./vinted_report_generator/main\nTime (mean ± σ): 208.3 ms ± 1.9 ms [User: 205.4 ms, System: 1.6 ms]\nRange (min … max): 204.9 ms … 210.6 ms 14 runs\n\nSummary\n./vinted_report_generator/main ran\n1.26 ± 0.03 times faster than ./boids_test/bin/Release/net7.0/linux-x64/publish/boids_test\n```\n" }, { "path": "bench/bench_closure.v", "content": "module main\n\nimport time\nimport sync\nimport os\nimport runtime\nimport v.util.version\n\n// Define closure type alias\ntype ClosureFN = fn () int\n\n// Test closures with different capture sizes\nfn create_closure_small() ClosureFN {\n\ta := 0\n\treturn fn [a] () int {\n\t\treturn a\n\t}\n}\n\nfn create_closure_medium() ClosureFN {\n\ta, b, c, d := 1, 2, 3, 4\n\treturn fn [a, b, c, d] () int {\n\t\treturn a + b -

Only Linux/macOS for now, requires `-use-coroutines` and\n `coroutines.sleep()` instead of `time.sleep()`. They work with IO and net, but not with GC\n for now.\n- `spawn` now spawns system threads, `go` spawns coroutines.\n- Static type methods: `Foo.new()` to replace factory functions like `new_foo()`.\n- Smartcasting with complex conditions:\n `if sum_type is Foo && !sum_type.is_info && get_name(sum_type.info.name) == 'foo' `.\n- Functions can now return fixed size arrays.\n- Enum values now can have attributes.\n- Generic functions as function parameters are now supported: `fn f[T](x T, i int, f_ Fn[T]) T { `.\n- Anonymous structs can no longer have attributes.\n- A new `[spawn_stack: 131072]` function attribute for controlling the max size of the stack\n of the spawned threads.\n- Channel pop now works with an `or` block: `ch := <-self.item or { return none }`\n- `it` has been renamed to `index` in array inits.\n- String interpolation simplified to just '${name}', enforced by vfmt,\n and updated in the entire code base.\n- `go foo()` has been replaced with `spawn foo()` (launches an OS thread, `go` will be used for\n upcoming coroutines instead).\n- vfmt now supports `// vfmt off` and `// vfmt on` for turning off the formatting locally\n for short snippets of code.\n Useful for keeping your carefully arranged matrices intact.\n- Match branch range expressions with consts: `match x { const1...const2 {} }`\n- Hot code reloading via `[live]` is now supported in imported modules, not just the main module.\n- Syntax sugar for map inits without needing explicit casts for interfaces:\n `all.children := { \"abc\": rect, \"def\": ui.rectangle()}`.\n- `$embed_file()` fixes, including variable args support.\n- `none` fixes: no longer allowed to be used as a separate type, `dump()` support,\n not allowed inside `unsafe`.\n- Const functions: `const y = term.yellow`, then `println(y('abc'))`.\n- Builtin type names can no longer be used as identifiers.\n- Generic `typeof[T]()`, `sizeof[T]()`, `isreftype[T]()` functions.\n- Deprecated `-error-limit` in favour of the documented `-message-limit` option.\n- Maps now support aliased keys.\n- Operator overloading now works with reference types.\n- Generic struct inits with nested generic structs and generic optional types are now allowed.\n- During array creation, `len:` is required when using default values for the array.\n- Optimized one byte `[]u8` arrays creation.\n- Recursive aliasing is no longer allowed (e.g. `type Alias = map[string]Alias`).\n- Easier custom error creation: `return MyCustomErr{}` instead of `return IError(MyCustomErr)`.\n- All floats outputs now have `.0` conditionally appended to them to improve clarity.\n- Custom integer enum types: `enum Xyz as u64 {`.\n- AST transformer fixes and optimizations.\n- Stylistic improvements and bug fixes in vfmt.\n- Casting integers to enums now requires `unsafe{}`.\n- Improved error and warning messages.\n- Parallel compilation now uses `sync.Pool`.\n- `-skip-unused` fixes, soon to be made the default.\n- Anonymous structs.\n- Lots of bug fixes: 90% of all bugs ever submitted are closed.\n- New keyword/type: `nil`. Only to be used inside `unsafe`. Replaces `voidptr(0)`.\n- V can now find code in the `src/` directory.
