mypy: error: expected '(' with 2023.8.2

[ogajduse]

I use homeassistant-stubs in the https://github.com/custom-components/feedparser repository.

I have bumped into an issue with the latest version of stubs.

 /home/runner/.cache/pre-commit/repoa5dodlk1/py_env-python3.11/lib/python3.11/site-packages/homeassistant-stubs/components/sensor/__init__.pyi:26: error: expected '('  [syntax]

The issue seems to be in stubs itself.

I have exactly the same issue.

For some reason, a method is being generated with a hyphen in the name (__mypy-replace), see https://github.com/KapJI/homeassistant-stubs/blob/main/homeassistant-stubs/components/sensor/__init__.pyi#L26

Still seeing this issue on 2023.8.3

I did a quick test and can tell the stub is generated correctly with MyPy 1.4.1
When MyPy is upgraded to 1.5.0 or 1.5.1 the extra function is generated causing the syntax error:

def __mypy-replace(

So it's definitely some regression bug in stubgen code.

Don't have time to create a bug report now at mypy.

Might be an idea for @KapJI to fix MyPy dependency to 1.4.1 for the time being so at least the stubs can be generated correctly now.
As things are completely broken atm.

Thanks for escalating it with mypy team!

Version 2023.11.2 was published which uses mypy 1.7.0. It has multiple improvements for dataclass stubs. Give it a try.
