Introduction of Argtable3

Argtable3 is an open source ANSI C library that parses GNU-style command-line options. It simplifies command-line parsing by defining a declarative-style API that you can use to specify what your command-line syntax looks like. Argtable3 will automatically generate consistent error handling logic and textual descriptions of the command line syntax, which are essential but tedious to implement for a robust CLI program.

Quick Start

Argtable3 is a single-file ANSI-C library. All you have to do is adding argtable3.c to your projects, and including argtable3.h in your source code.

If you have modified Argtable3 and want to quickly verify whether the modifications break any existing code or not, you can run the following commands in the project root directory to build both examples and unit tests and run unit tests:

  • If you use GCC (Linux, MinGW, Cygwin), type:

    $ make
    

    To cleanup, type:

    make cleanall
    
  • If you use Microsoft Visual C++ compiler, type:

    $ nmake /f Makefile.nmake
    

    To cleanup, type:

    nmake /f Makefile.nmake cleanall
    

If you want to use CMake to generate Visual Studio 2017 x64 solution file, type:

$ mkdir build
$ cd build
$ cmake -G "Visual Studio 15 2017 Win64" ..

To cleanup, just remove the build directory.

Documentation and Examples

To learn how to use the Argtable3 API, you can see the documentation on the web site, or examples in the examples folder.

To build the examples, open the console window of your favorite development environments, go to the examples folder, and use the included Makefiles to build the examples.

  • If you use GCC (Linux, MinGW, Cygwin), type:

    $ make
    

    To cleanup, type:

    make cleanall
    
  • If you use Microsoft Visual C++ compiler, type:

    $ nmake /f Makefile.nmake
    

    To cleanup, type:

    nmake /f Makefile.nmake cleanall
    

Unit Tests

Argtable3 is a BSD-licensed open source library, so you can modify the library anyway you want. However, before committing your code to your own repository or the Argtable3 official repository, please make sure your changes can pass the unit tests included in the distribution.

To build and run the unit tests, open the console window of your favorite development environments, go to the tests folder, and use the included Makefiles to build and run the unit tests.

  • If you use GCC (Linux, MinGW, Cygwin), type:

    $ make
    

    To cleanup, type:

    make cleanall
    
  • If you use Microsoft Visual C++ compiler, type:

    $ nmake /f Makefile.nmake
    

    To cleanup, type:

    nmake /f Makefile.nmake cleanall

Argtable 2.x uses getopt from GNU, which is LGPL licensed. In order to switch to BSD, we replaced GNU getopt with NetBSD getopt. We really appreciate this high quality library that lays the foundation of Argtable 3.x and here is its copyright notice:
