Additional classes for argparse

Project description

Python argparse.ArgumentParser subclass(es)

Quick example of argparser declaration from dictionary:

import sys
from argparse.extra import DictArgumentParser

def run_testarg_processing(args, argv):
    print 'testarg argument used'

ARGUMENTS = {'--use-something':{'dest':'use_something',
                 #sub:testarg will create subparser 'testarg'
                 #depth of subargs is unlimited
                 'description':'Test arg subcommand',
                 'help':'Test help'

DEFAULTS_ONLY = ['func',]
def get_argparser(argsdict=ARGUMENTS):
    #always create get_argparser function for your cli apps
    #this will enable easy integration of subsequent applications
    #with your argparser
    return DictArgumentParser(argsdict, DEFAULTS_ONLY)

def main(args=sys.argv):
    args, argv = get_argparser().parse_known_args(args[1:])
    args.func(args, argv)

if __name__ == '__main__':
