• Use PEP 621 compliant pyproject.toml
• Update README to add instructions how to generate the example reports

pandas-stubs and matplotlib-stubs are required only for type checking, not at runtime, therefore it is not necessary for users to install them. I'll leave these out or I'll add them to a dev extra dependencies group. My preference would be to leave them out as other development dependencies are not listed.

SGTM @dnicolodi I'll merge this quick and try it out though, can be done later

[andreasgerstmayr]

You're right, I overlooked this when I converted it from poetry to PEP 621.
I've created a follow-up PR #39 to fix this and also added ruff and mypy to the dev dependencies.

Still doesn't work with uv, I think the problem is my pypi auth token.
This is why I never bother with packaging
Now I have to chase down another token problem

[dnicolodi]

That's why I do all releases from CI 🙂 Trusted Publishers remove the need to care about access credentials to PyPI. I recently updated benagulp and beancount to use that.

I don't know it feels every time I have to use PyPI I have problems

Found it. Token was buried deep elsewhere.
But now it's unhappy about license-file usage, and we don't use it.
(Why does packaging universally sucks so bad?)

  Caused by: Upload failed with status code 400 Bad Request. Server says: 400 license-file introduced in metadata version 2.4, not 2.2. See https://packaging.python.org/specifications/core-metadata for more information.

Here's the problem
astral-sh/uv#9513

Somehow @dnicolodi you're mentioned on the root cause issue
pypa/setuptools#4759

Anyhow, I used the workaround.
Managed to cut a release.

[dnicolodi]

It is a setuptools bug pypa/setuptools#4759.

Very recent twine releases have a work around for it. It is however not a bad idea to have setuptools generate valid metadata: add this to pyproject.toml:

[tool.setuptools]
license-files = []

I hope they are saying good things 😄 I've been doing some work on the packaging tools recently

Thank you both! 💯
