Lint pyproject.toml according to the 'Declaring project metadata' spec

[not-my-profile]

Declaring project metadata (based on PEP 621) defines how metadata in pyproject.toml should be defined. Unless I am missing something there doesn't appear to be an existing lint plugin we could model this after, which would make this a RUF check.

This is basically the same idea as rust-lang/rust-clippy/issues/6431 but for Python/pyproject.toml/ruff instead of Rust/Cargo.toml/clippy.

Sidenote: Maybe we want to use pyproject-toml-rs for the parsing step?

(I know there's validate-pyproject but it may not be relevant at all, I haven't looked closely.)

[not-my-profile]

Oh, yes I did miss that ... it does appear to be relevant. Although our checks could probably be more in-depth.

[charliermarsh]

(I really haven't looked at that project at all, it was just the first thing that came to mind, maybe unhelpful...)

There is also taplo that is more general which is

A TOML parser, analyzer and formatter library
