yarg ⎇

Yet another UNIX-like argument parser for C99. 0BSD-licensed.

Why another argument parsing library? ⎇

Four reasons:

• yarg is a header-only library, meaning that you can simply copy-and-paste it into project. It is also 0BSD-licensed, meaning that you can use it in just about any program without complicated or undesirable licensing obligations.
• yarg supports short and long options, Windows-style flags /like-this and short flag styles -like -this=3, not just the UNIX-y -ab5 --like-this.
• yarg actually parses the arguments and gives you a structure that is fundamentally independent of the contents of argv.
• yarg supports mixed positional arguments with flags, e.g. --flag file_name.txt --flag2.

Despite being more featured than argument parsers like getopt or getopt_long, yarg retains a relatively small code footprint (300 LoC).
