A simple library to handle command line of an application with support for subcommands, as well as, automatic help text extraction from doc strings.

• python 2.7 / 3.4
• Linux / Windows

• Decorator as well as subclass based command addition.
• Custom help text formatter which improves upon the rather lousy default formatter.
• Automatic help text extraction from doc strings.
• Autocomplete support (Linux only).

A simple case of just the main command (without any subcommands):

from redcmd.api import maincmd, execute_commandline

@maincmd
def main(a, b):
        '''Add two numbers.
        a:  first number
        b:  second number

        This is where extra help text goes.
        It can be more than one line.'''

        try:
                print('sum: %d'%(int(a) + int(b)))
        except ValueError:
                print('bad integer')
                raise CommandError()

execute_commandline()
