caipyrinha

Abstraction layer over argparse.

Caipyrinha added 2 methods to argparse.ArgumentParser, callback and parse_wc. Also a Caipyrinha instance is callable and is equal to use parse_wc method.

Example of use:

.. code-block:: python

# ex.py

import caipyrinha

parser = caipyrinha.Caipyrinha(prog="Your Program")
parser.add_argument("--version", action='version', version="%(prog)s 0.1")

@parser.callback(exit=0, exclusive="group1")
def first(flags, returns):
    '''Execute this option and exit'''
    print "bye bye"

@parser.callback(action="store")
def second(flags, returns):
    '''set his own return value with his parameter'''
    return flags.second

@parser.callback("--third", exclusive="group1")
def no_used_name(flags, returns):
    '''you cant use this argument with first'''
    print returns.second

import sys
parser(sys.argv[1:])
