redcmd 1.1.0

A library to manage command line interface for an application.

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

Supported platforms

• python 2.7 / 3.x

• Linux / Windows

Features

• 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.

Usage

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

from redcmd import maincmd, CommandLine, CommandLineError

@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()

cmdline = CommandLine()
try:
        cmdline.execute()
except CommandLineError as e:
        print(e)
