CLAP aims at being powerful and advanced command line interface library for Python 3 language. Having built-in support for modes, optional and obligatory options, options with arguments (with type-checking with arbitrary types) it enables programmers to create rich command line interfaces for Python 3 programs.
- support for single-level and nested modes (with per-mode and global options),
- support for grouped short options (
ls -lhR), - support for long options with or without equal-sign-connected arguments (
--log=./file.logand--log ./file.logareboth correct), - support for option aliases (short/long names),
- support for typed arguments (
str,int,floatbuilt-in and other arbitrary types via callbacks), - built-in type checking of option arguments,
- support for multiple arguments (e.g.
--point 0 0), - checking for missing arguments with options which require them,
- checking for conflicting options (eg.
--quietmust not come with option--verbose), - support for options that MUST be passed to the program,
- support for options required by other options (e.g.
--keyrequires--value), - support for options wanted by other options (e.g.
--whichwants--thisor--thator both), - good set of exceptions with detailed error messages,
- ability to load interface from JSON descriptions,
