Click decorated functions exit on --help

[unode]

Since click is designed to wrap commands, some instructions, such as --help, trigger a system exit. If a sufficiently high number of requests is made, all threads will eventually be exhausted and the bot will stop responding.

How To Reproduce

1. Decorate a function with @click.command
2. Send command --help and see the thread die with click.exceptions.Exit: 0.

Expected behavior --help should not trigger a system exit or kill the thread. In general, worker threads should not die if an exception is raised.

Operating Environment (please complete the following information):

• OS: Linux
• Python Version: 3.9
• mmpy_bot Version: 2.0 - git

Ah nice catch, I've run into this before in other projects. It's a fairly easy fix I think, we can just catch a specific exception
