python-command-line.md

1. Create a setup.py:

  #!/usr/bin/env python

  from distutils.core import setup

  setup(
      name='My Thing',
      version='1.0',
      description='Does these things',
      scripts=['scripts/thing'],
  )

2. Create the file ./scripts/thing and add:

  #!/usr/bin/env python
  import argparse
  
  if __name__ == "__main__":
      parser = argparse.ArgumentParser(description='Thing helper')
      parser.add_argument('command', type=str, choices=['install'])
      args = parser.parse_args()

      if args.command == 'install':
        # do something.  
        
      # add additional choices and handle here for positional arguments

3. Install with pip editable -e .
4. Now call anywhere with thing install
