pyopt

pyopt version 0.84

A 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

expose = pyopt.Exposer()

@expose.args
def regular_function(arg1:str, arg2:int):
    '''Your help - the docstring'''
    # bla, etc, foobar spam...
    print(repr(arg1), repr(arg2))

if __name__ == "__main__":
    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 True. 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.
