Argsrun

Simple tool for creating pluggable commands and sub-commands.

Usage example:

# in setup.py of your project specify argsrun entry point in console scripts
# and provided commands as follows:

setup(name="MyProj",
      # ...
      entry_points={
        'console_scripts': [
            'myproj = argsrun:main',  # argsrun will handle main command
        ],
        'myproj': [                   # ...and lookup for this subcommands
            'main = myproj:main',
            'run = myproj.module:run',
        ],
      })

In case you have several packages/projects and you want them to share same entry point, you can easily do it like follows:

# my-frontend-app/setup.py

setup(name="MySite Frontend",
      entry_points={
        'console_scripts': [
            'mysite = argsrun:main',
        ],
        'mysite': [
            'serve-frontend = frontend:serve',
        ]
      })

# my-backend-app/setup.py

setup(name="MySite Admin backend",
      entry_points={
        'console_scripts': [
            'mysite = argsrun:main',
        ],
        'mysite': [
            'serve-admin = backend:serve',
        ]
      })

 # In my-frontend-app/frontend/__init__.py

 import argsrun

 def handler(options):
     # Run frontend app
     pass

 def parser_setup(ap):
     ap.add_argument('--port', help="Port to bind to")

 main = argsrun.Entry(handler, parser_setup)
