python cli scripts for humans

Project description

Easy python cli scripts for people that just want get things done.

Captain was lovingly crafted for First Opinion.


A valid captain cli script needs two things:

  1. a shebang on the first line

    #!/usr/bin/env python
  2. a main function

    def main(foo, bar):
        return 0

That’s it! Whatever arguments you define in the main function will be options on the command line.

def main(foo, bar):
    return 0

can be called on the command line:

$ pyc path/to/ --foo=1 --bar=2


A typical standard python cli script:

import argparse

if __name__ == u'__main__':
    parser = argparse.ArgumentParser(description='fancy script description')
    parser.add_argument("--foo", action='store_true')
    parser.add_argument("--bar", default=0, type=int)
    parser.add_argument("args", nargs='*')
    args = parser.parse_args()

would become:

#!/usr/bin/env python

def main(foo=False, bar=0, *args):
    '''fancy script description'''
    return 0

You can get a list of all available scripts in a directory by running captain with no arguments:

$ captain


Use pip:

$ pip install captain
