Command Line Argument Processor in C

CLAP (C) Command Line Argument Processor

A lightweight argument processor for C in a header only format. The full implementation is included by default, since most programs only parse arguments in main.

To use simply:

#include "clap.h"

If you want to exclude the implementation, you should define the macro:

#define CLAP_NO_IMPLEMENTATION

An example can be found in clap_example.c and clap_example_two.c. To run, simply compile with any standard C compiler, then run. For example:

$ cc -o clap_example clap_example.c
$ ./clap_example --dimensions 1280x720 -f png
Outputting image with dimensions: 1280x720
And format: png

$ cc -o clap_example_two clap_example_two.c
$ ./clap_example_two file.txt -lpc
Reading from:  file.txt
Outputting to: STD_OUT
