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()
