Argument-parsing helpers for C/Unix

Question

I know of the following:

• The venerable getopt(3)
• The extended getopt_long
• glibc\'s argp parser for Unix-style argum

Answer 1

I have been developing and using libparamset that is a command-line parameter parsing library written in plain C. It provides:

• Cross-platform functionality (Linux, OS X, Windows).
• Configurable parser where each parameter can act differently (powerful and flexible feature).
• Auto-generated messages for typos, unknown parameters or invalid parameters.
• Extra functionality to design command-line user interface.
• Good documentation.
