Why removing the if __name__ == '__main__' statements?
It is not a Python 2 compliance; see Python 3 documentation here

[mochaaP]

It's not removed, it's wrapped into a run function so we can use it in the script entrypoint later.

[elicn]

Oh, I see.. I must have missed that.

[elicn]

@mochaaP, what's with that .gitignore? It is full of redundant auto-generated stuff. Can you reduce it to the absolute necessary?

[mochaaP]

I don't think that's a particularly big issue?

[mochaaP]

The gitignore is just https://github.com/github/gitignore/blob/main/Python.gitignore with a few extra additions (poetry local config, ruff cache and pyright config).

[elicn]

We strive to keep the code clean as much as possible.
Please remove all redundant auto-generated additions.

[mochaaP]

Reduced to minimum while keeping the required for Poetry.

[mochaaP]

@xwings Ready for merge :)

[elicn]

.gitignore is still full of auto-generated stuff, but whatever.

[mochaaP]

Rebase & more cleanups.
