Ascetic command runner. The most ease way to power your python app with custom management commands
Ascetic Command Runner
Not all of our projects are using either django or another God framework. So, once we start our hobby project, would be great to put into the game some commands. For example, maybe we need for our hobby project simple command test which loads custom TestRunner, etc In this case this package maybe handy for you!
Simply run in your bash:
pip install acmdrunner
In your django like manage.py command loader, you need to trigger following:
import os from acmdrunner import Loader ... make all your preparations, initialize project settings, etc ... Loader.load_from_directory(os.path.dirname(__file__)) Loader.load_from_package('rit.app')
Loader will search recursively in passed folder for folders with name management. And try to load from folders found file acr_commands.py
An example of the file acr_commands.py:
from acmdrunner.dispatcher import CommandDispatcher command_dispatcher = CommandDispatcher() def execute(*args): pass command_dispatcher.register_command('test', execute)
register_command registers specific command and handler for this command. Your commands should implement execute method. Better to inherit from BaseCommand. But as it is ascetic, you can simply pass class with execute method implemented. That’s all!
To run command, please trigger following call:
from your_package_place import command_dispatcher command_dispatcher.execute_command(command_name, *args, **kwargs)
Real usage example
If you want to load all commands from specific namespace, you can implement following:
packages_to_traverse = ('rit.app', 'rit.core') for package in packages_to_traverse: Loader.load_from_package(package) Loader.load_from_directory(os.path.dirname(os.getcwd()))
