Powerful and advanced command line interface building library

Project Description

# RedCLAP - Command Line Arguments Parser (Redesigned)

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.


## Features of CLAP:

* 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.log` and `--log ./file.log` are both correct),
* support for option aliases (short/long names),
* support for typed arguments (`str`, `int`, `float` built-in and other arbitrary types via callbacks),
* built-in type checking of option arguments,
* support for multiple arguments for options (e.g. `--point 0 0`),
* checking for missing arguments with options which require them,
* checking for conflicting options (eg. `--quiet` must not come with option `--verbose`),
* support for options that MUST be passed to the program,
* support for options *required by* other options (e.g. `--key` requires `--value`),
* support for options *wanted by* other options (e.g. `--which` wants `--this` or `--that` or both),
* good set of exceptions with detailed error messages,
* ability to load interface from JSON descriptions,
* automatic generation of help screens (for `your-tool help` command) with per-mode, per-option, and per-operand descriptions,
usage examples, and more

CLAP is not the most easy to use command line arguments parser for Python, but I am quite confident that it is one
of the most powerful (if not *the* most powerful) framework for writing command line interfaces.
With excellent support for modes, options, and operands, automatic input verification, and help screen generation you
get a big return on your investment.
