Argue

Argue is a command line parser, intended to make writing command line applications easy and painless. It uses built-in Python types (lists, dictionaries, etc) to define options, which makes configuration clear and concise. Additionally it contains possibility to handle subcommands (e.g. git commit or svn obliterate).

Quick example

That's an example of an option definition: ::

import sys import argue

@argue.command(usage='%name [-n] MESSAGE') def main(message, nonewline=('n', False, 'no newline')): 'Simple echo program' sys.stdout.write(message) if not nonewline: sys.stdout.write(' ')

if name == 'main': main()

Running this program will print the help::

echo.py [-n] MESSAGE

Simple echo program

options:

-n --nonewline no newline -h --help show help

I think this mostly describes what's going on, except that I'd like to mention one interesting feature - if you are using long name for option, you can use only partial name, for example ./echo.py --nonew a is valid command line. This is also true for subcommands: read about that and everything else you'd like to know in documentation_.
