I support the goal of this PR but I think it's not likely that it will be merged. It's doing too many things at once. My recommendation would be to create the most basic ruff setup with ruff.toml in an initial PR, then follow it up with new PRs adding the rules and applying fixes.

[ulgens]

I'd recommend adding an action for pre-commit hooks, instead of a ruff-only config.

@mikemanger Would you mind rebasing this branch over #185 ?

Superseded by the collection of following PRs:

• Introducing black formatting #185
• Switch to ruff #189
• Enrich ruff config #190
