The benefits of this solution are that we have a control over the decorator and we can pass some custom *args, **kwargs to the decorated functions.

• New python file in actions/ folder
• Create function with an appropriate name (ex. action_onclick)
• Decorate the function with register_action decorator
• Export the function in the __all__ method in actions/__init__.py file

After that the function will be avaliable at the register in the main.py file.

$ python main.py
[<function action_example1 at 0x000001CC3F88D310>, <function action_example2 at 0x000001CC3F88D3A0>]

Measure-Command { python .\main.py }
