simple argument parser like as python-fire

Project description

a simple tiny wrapper of argument parser

  • There are already pairs of optional keywords and default values and types in function signature, and docstring as a description. just use it!
  • no more verbose code for command line options :)

write sample.py

# sample.py

def main(pos1, pos2, kw1=1, kw2=2):
    """
    dostring as a help string
    :param pos1:
    :param pos2:
    :param kw1:
    :param kw2:
    :return:
    """
    pass


if __name__ == '__main__':
    import autoarg
    autoarg.run(main)

just run

$ python sample.py -h

$ python sample.py --help
usage: sample.py [-h] [--kw2 KW2] [--kw1 KW1] pos1 pos2

    dostring as a help string
    :param pos1:
    :param pos2:
    :param kw1:
    :param kw2:
    :return:


positional arguments:
  pos1
  pos2

optional arguments:
  -h, --help  show this help message and exit
  --kw2 KW2   kw2 : default = 2
  --kw1 KW1   kw1 : default = 1

if you need complex one, consider python-fire
