This repository is unmaintained. Go [here](https://github.com/bfgroup/Lyra) for a fork that is somewhat maintained. !!\n\n-----------------------------\n\n\nA simple to use, composable, command line parser for C++ 11 and beyond.\n\nClara is a single-header library.\n\nTo use, just `#include \"clara.hpp\"`\n\nA parser for a single option can be created like this:\n\n```c++\nint width = 0;\n// ...\nusing namespace clara;\nauto cli\n = Opt( width, \"width\" )\n [\"-w\"][\"--width\"]\n (\"How wide should it be?\");\n```\n\nYou can use this parser directly like this:\n\n```c++\nauto result = cli.parse( Args( argc, argv ) );\nif( !result ) {\n std::cerr << \"Error in command line: \" << result.errorMessage() << std::endl;\n exit(1);\n}\n\n// Everything was ok, width will have a value if supplied on command line\n```\n\nNote that exceptions are not used for error handling.\n\nYou can combine parsers by composing with `|`, like this:\n\n```c++\nint width = 0;\nstd::string name;\nbool doIt = false;\nstd::string command;\nauto cli\n = Opt( width, \"width\" )\n [\"-w\"][\"--width\"]\n (\"How wide should it be?\")\n | Opt( name, \"name\" )\n [\"-n\"][\"--name\"]\n (\"By what name should I be known\")\n | Opt( doIt )\n [\"-d\"][\"--doit\"]\n (\"Do the thing\" )\n | Arg( command, \"command\" )\n (\"which command to run\");\n```\n\n`Opt`s specify options that start with a short dash (`-`) or long dash (`--`).\nOn Windows forward slashes are also accepted (and automatically interpretted as a short dash).\nOptions can be argument taking (such as `-w 42`), in which case the `Opt` takes a second argument - a hint,\nor they are pure flags (such as `-d`), in which case the `Opt` has only one argument - which must be a boolean.\nThe option names are provided in one or more sets of square brackets, and a description string can\nbe provided in parentheses. The first argument to an `Opt` is any variable, local, global member, of any type\nthat can be converted from a string using `std::ostream`.\n\n`Arg`s specify arguments that are not tied to options, and so have no square bracket names. They otherwise work just like `Opt`s.\n\nA, console optimised, usage string can be obtained by inserting the parser into a stream.\nThe usage string is built from the information supplied and is formatted for the console width.\n\nAs a convenience, the standard help options (`-h`, `--help` and `-?`) can be specified using the `Help` parser,\nwhich just takes a boolean to bind to.\n\nFor more usage please see the unit tests or look at how it is used in the Catch code-base (catch-lib.net).\nFuller documentation will be coming soon.\n\nSome of the key features:\n\n- A single header file with no external dependencies (except the std library).\n- Define your interface once to get parsing, type conversions and usage strings with no redundancy.\n- Composable. Each `Opt` or `Arg` is an independent parser. Combine these to produce a composite parser - this can be done in stages across multiple function calls - or even projects.\n- Bind parsers directly to variables that will receive the results of the parse - no intermediate dictionaries to worry about.\n- Or can also bind parsers to lambdas for more custom handling.\n- Deduces types from bound variables or lambdas and performs type conversions (via `ostream <<`), with error handling, behind the scenes.\n- Bind parsers to vectors for args that can have multiple values.\n- Uses Result types for error propagation, rather than exceptions (doesn't yet build with exceptions disabled, but that will be coming later)\n- Models POSIX standards for short and long opt behaviour.\n\n## Roadmap\n\nTo see which direction Clara is going in, please see [the roadmap](Roadmap.md)\n\n## Old version\n\nIf you used the earlier, v0.x, version of Clara please note that this is a complete rewrite which assumes C++11 and has\na different interface (composability was a big step forward). Conversion between v0.x and v1.x is a fairly simple and mechanical task, but is a bit of manual\nwork - so don't take this version until you're ready (and, of course, able to use C++11).\n\nI hope you'll find the new interface an improvement - and this will be built on to offer new features moving forwards.\nI don't expect to maintain v0.x any further, but it remains on a branch.\n" }, { "path": "Roadmap.md", "content": "# Roadmap\n\n## June 2019 Update\n\nPreviously this roadmap said, \"I'm not quite ready to throw development fully open to the community effort\". The intention had been to clarify the direction in the codebase in some key areas, as many of the PRs were taking it in different directions.\n\nUnfortunuately the time intended for working on this has not appeared and this project has languished in neglect as a result. I should have acknowledged that sooner, but as of now I (@philsquared), am opening this up fully to the community (anyone who is still interested). That means, of course, that maintainers such as @horenmar, will be able to merge PRs as they see fit (as well as make any other changes). It also means that we'd be keen to hear from anyone that wants to take the lead in maintaining and evolving the library.\n\nPersonally, I still hope to contribute further to the project, but am no longer in a position I can commit to leading it.\n\nHere are the items I had on the original roadmap, for reference. It is not a hard requirement to follow them:\n\n- Add more documentation (includes [#49](https://github.com/catchorg/Clara/issues/49))\n- Finish work on \"required\" parsers [#39](https://github.com/catchorg/Clara/issues/39), [#16](https://github.com/catchorg/Clara/issues/16) & [PR #28](https://github.com/catchorg/Clara/pull/28)\n- Finish work on removing exceptions completely (or making them \"optional\")\n- (compiler conditional) Support for `std::optional` and maybe other optional types (e.g. boost) [#4](https://github.com/catchorg/Clara/issues/4) & [PR #45](https://github.com/catchorg/Clara/pull/45) - this is mostly, if not entirely, implemented. Should be checked, and #4 closed if so.\n- Arg\\[0] support on Windows [#29](https://github.com/catchorg/Clara/issues/29)\n- config files and environment variables\n- \"hidden\" options [#29](https://github.com/catchorg/Clara/issues/29)\n- Capture general text for help output [#48]((https://github.com/catchorg/Clara/issues/48)\n- subcommands [#31](https://github.com/catchorg/Clara/issues/31) (I actually have a design mostly done for this) - but see also [PR #32](https://github.com/catchorg/Clara/pull/32)\n\n---\n\n" }, { "path": "appveyor.yml", "content": "version: \"{build}\"\n\nbranches:\n except:\n - /dev-travis.+/\n\nos:\n - Visual Studio 2017\n - Visual Studio 2015\n\nenvironment:\n matrix:\n - additional_flags: \"/permissive- /std:c++latest\"\n - additional_flags: \"\"\n\nmatrix:\n exclude:\n - os: Visual Studio 2015\n additional_flags: \"/permissive- /std:c++latest\"\n\ninit:\n - git config --global core.autocrlf input\n\ninstall:\n - ps: if (($env:CONFIGURATION) -eq \"Debug\" ) { python -m pip --disable-pip-version-check install codecov }\n - ps: if (($env:CONFIGURATION) -eq \"Debug\" ) { .\\misc\\installOpenCppCoverage.ps1 }\n\n# Win32 and x64 are CMake-compatible solution platform names.\n# This allows us to pass %PLATFORM% to CMake -A.\nplatform:\n - Win32\n - x64\n\n# build Configurations, i.e. Debug, Release, etc.\nconfiguration:\n - Debug\n - Release\n\n#Cmake will autodetect the compiler, but we set the arch\nbefore_build:\n - set CXXFLAGS=%additional_flags%\n # Indirection because appveyor doesn't handle multiline batch scripts properly\n # https://stackoverflow.com/questions/37627248/how-to-split-a-command-over-multiple-lines-in-appveyor-yml/37647169#37647169\n # https://help.appveyor.com/discussions/questions/3888-multi-line-cmd-or-powershell-warning-ignore\n - cmd: .\\misc\\appveyorBuildConfigurationScript.bat\n\n \n# build with MSBuild\nbuild:\n project: Build\\Clara.sln # path to Visual Studio solution or project\n parallel: true # enable MSBuild parallel builds\n verbosity: normal # MSBuild verbosity level {quiet|minimal|normal|detailed}\n\ntest_script:\n - set CTEST_OUTPUT_ON_FAILURE=1\n - cmd: .\\misc\\appveyorTestRunScript.bat\n" }, { "path": "codecov.yml", "content": "codecov:\n branch: master\n\ncoverage:\n ignore:\n - \"src/*\"\n - \"third_party/catch.hpp\"\n" }, { "path": "docs/release-notes.md", "content": "\n\n# 1.1.3\n\n## Improvements\n* `Args` now take arguments as `int argc, char const * const * argv`.\n * This allows the use of string literals for arguments\n\n\n# 1.1.2\n* Fix usage of `dynamic_cast` preventing Clara being used with `-fno-rtti`\n\n\n# Older versions (1.1.1 and earlier)\n\nNo release notes have been kept (Maybe some of it will be backfilled later)\n" }, { "path": "include/clara.hpp", "content": "// Copyright 2017 Two Blue Cubes Ltd.
