Generic: hardcoded `help` and `version` options.\n2. Optional: user defined.\n3. Mandatory: user defined.\n\nThe following diagram shows the arguments handling logic:\n\n![](doc/diagram/ArgsHandling-ActivityDiagram.png)\n\n## Usage\n\nThis project contains a simple example of how to use the library that covers the basic cases of options/arguments usage.\n\nExample source code: [test/component_test/main.cpp](test/component_test/main.cpp)\n\n### How to build example\n\n```\n$ mkdir build \u0026\u0026 cd build\n$ cmake -Dprog-arg-manager_BUILD_TESTS=on ..\n$ make\n```\n\nExecutable binary `prog-arg-manager-ctest` is here:\n```\n$ cd build/test/component_test\n```\n\n### How to run example\n\nRun example without all mandatory options or with \"-h [ --help ]\", help text should be shown:\n```\n$ ./prog-arg-manager-ctest -h\nAllowed options:\n\nGeneric:\n  -h [ --help ]          display this help text and exit\n  -v [ --version ]       display version information and exit\n\nOptional:\n  --num arg              to test numeric arguments\n  -r [ --read ]          read flag to test boolean\n  -w [ --write ]         write flag to test boolean\n  -d [ --delete ]        delete flag to test boolean\n\nMandatory (last option name can be omitted):\n  -p [ --path ] arg      path to test string\n  -f [ --files ] arg     files to test vector\u003cstring\u003e\n```\n\nRun example with \"-v [ --version ]\" to show version:\n```\n$ ./prog-arg-manager-ctest -v\n1.0.0\n```\n\nRun example with all mandatory options:\n```\n$ ./prog-arg-manager-ctest --num 789 -rw -p /path/to/my/dir file1.txt file2.txt file3.txt\nnum:   789\nread:  1\nwrite: 1\ndel:   0\npath:  /path/to/my/dir\nfiles: \n       file1.txt\n       file2.txt\n       file3.txt\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnkh-lab%2Fprog-arg-manager","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnkh-lab%2Fprog-arg-manager","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnkh-lab%2Fprog-arg-manager/lists"}
