I'd like to automate our auto-formatter with pyink and type checking (say, via mypy) at the very least. To close this issue, let's document using this pre-commit rule in the contributing guide.

what's your opinion on ruff instead of pyink ? Also please check https://github.com/alxmrs/xarray-sql/pull/91

[alxmrs]

I am happy with either! When I started this project, I was more familiar with pyink than ruff, but these days I primarily use the former.

Is this closed by #91? I see that usage is also documented in https://github.com/alxmrs/xarray-sql/blob/main/CONTRIBUTING.md

[alxmrs]

That's right. Closed by #91. Thanks Charles.
