Exposing python functions to the command line.

Project description

pyopt version 0.71 - http://code.google.com/p/pyopt/

A python 3 module for command-line options with a pythonic, decorator-centric
syntax.

The following example auto-generates help with docstrings, type casting for
arguments and enforcing argument count:

import pyopt
import random

expose = pyopt.Exposer()

@expose.args
def roll_dice(number_of_faces:int, repetitions:int):
'''
Roll the dice to see if you are lucky or for general D&D pleasure.
number_of_faces - the max value of the die.
repititions - the amount of times to throw the dice.
'''
for i in range(repetitions):
print(random.randint(1, number_of_faces))


expose.run()

There are 3 modes of operation:
1. expose.args - A decorator for positional arguments.
2. expose.kwargs - A decorator for keyword arguments.
3. expose.mixed - A decorator for keyword and positional arguments.

Currently known compromises that are open to discussion, e-mail me:
1. This module was specifically designed with python 3 in mind, certain
features
can be converted to python 2.x, but the awesome ones can't.
2. Keyword command-line functions require every argument to start with a
different letter to avoid collisions.
3. Annotations aren't mandatory, I don't know if this is the right way to
go,
it's an explicity vs convenience issue.
4. Booleans can't default to false. I couldn't think of a use case for this
so tell me if you did.

License: whatever, I don't mind. Google Code made me choose so I went with
the "New BSD". If somebody has a better idea, e-mail, comment or whatnot.
Hearing from whoever uses this code would be nice, but you really shouldn't
feel obliged.
