CLI sub-command library

Project description

This is a tiny library to help you write CLI applications with many sub-commands.

Installation

pip install subc

Use

Create your own command subclass for your application (optional, but encouraged):

class MyCmd(subc.Command):
    pass

Then, write commands in your application which sub-class this:

class HelloWorld(MyCmd):
    name = 'hello-world'
    description = 'say hello'
    def run(self):
        print('hello world')

Finally, use your application-level subclass for creating the argument parser and running your application:

def main():
    parser = argparse.ArgumentParser(description='a cool tool')
    MyCmd.add_commands(parser)
    args = parser.parse_args()
    args.func(args)
