argrun

a library that wraps argparse, mapping arguments to decorated functions

functions are only called if the associated command line argument is present/non-empty

Installation:

$ pip install argrun

Usage:

from functools import reduce
import argrun 

runner = argrun.ArgumentRunner()

@runner.parse('-m', '--multiply', help='multiplies numbers', nargs='*')
def multiply(args):
    print(reduce(lambda x,y: x * y, map(int, args)))

if __name__ == '__main__':
    runner.run()
