Registerer

Implement maintainable and easy to use registry patterns in your project.

TLDR

Write this:

import registerer

command_handler_registry = registerer.Registerer()


@command_handler_registry.register()
def info(args):
    return "how can i help you?"


@command_handler_registry.register()
def play(args):
    return "let me play a song for you"


command = "info"
args = {}
assert command_handler_registry[command](args) == "how can i help you?"

Instead of this, which violates the Open-Closed Principle (OCP):

def info(args):
    return "how can i help you?"


def play(args):
    return "let me play a song for you"


def command_handler(command, args):
    if command == "info":
        return info(args)
    if command == "play":
        return play(args)


command = "play"
args = {}
assert command_handler(command, args) == "let me play a song for you"
