The Lean Mean C++ Option Parser handles the program arguments (argc, argv). It supports the short and long option formats of getopt(), getopt_long() and getopt_long_only() but has a more convenient interface. It is a freestanding, header-only library with no dependencies, not even libc or STL. It comes with a usage message formatter that supports column alignment and line wrapping, making it ideal for localized messages with different lengths.
Features
- Header-only library. Just #include "optionparser.h" and you're set.
- Freestanding. There are no dependencies whatsoever, not even the C or C++ standard library.
- Usage message formatter that supports column alignment and line wrapping.
- Unlike getopt() and derivatives it doesn't force you to loop through options sequentially. Instead you can access options directly like this:
- if ( options[QUIET] ) ... //Test for presence of a switch in the argument vector:
- if ( options[FOO].last()->type() == DISABLE ) ... // --enable-foo/--disable-foo: last one used wins
- int verbosity = options[VERBOSE].count(); // -v verbose, -vv more verbose
- for (Option* opt = options[FILE]; opt; opt = opt->next()) // go through all --file=<fname> arguments
