The package is typed but there is no py.typed file

[hatal175]

You went through the trouble of typing your package - adding a py.typed file to it will help type analysis.

Hey and thanks for the hint. I actually didn't know about the py.typed marker and thought that MyPy would pick up type hints automatically. So it is enough to create an empty py.typed file and include it in package_data in setup.py?

I think so

A py.typed marker is added in commit be7b3a9. However, this won't work at the moment. 😞 PEP561 mentions:

This PEP does not support distributing typing information as part of module-only distributions or single-file modules within namespace packages.

The single-file module should be refactored into a package and indicate that the package supports typing as described above.

So, as long as this project is a single-module project, no py.typed marker will be installed and thus, MyPy won't detect the typing support. I plan to restructure the project anyway to support Windows, so I can merge this change later...

Thanks for the response! Up to you whether to keep the issue open or not.
