Do we want to switch to ruff-format? I think it deserves some discussion.

I am all for it. When doing that in xvec I was just curious but the ruff extension in VS Code is so good that I actually noticed a difference compared to black. And it is one less tool to deal with.

I am also all for it after realizing how simple the switch was, but also agree that we might want a broader discussion and approval. Shall we open an actual issue for this (and keep this PR open), or have more of a discussion in here?

[martinfleis]

I think it is fine to have it here.

[martinfleis]

Giving a formal approval to show my support.

[knaaptime]

interesting, hadnt seen xvec. We started doing something like that when geosnap started, but it became clear quickly that a long-form geodataframe was far better in our case (since vectors often have different geoms in different time slices...) anyway, another tangent :)

fine with the switch. I use the ruff extension in vscode locally

[gegen07]

Looks good to me! Simplifying the environment is always a good enhancement.

@knaaptime Can you hit approve to make it more "formal?" 🤵‍♂️

[jGaboardi]

Nows this PR has 3 approvals. @gegen07 @knaaptime @martinfleis Shall we wait another week or so to see if anyone else has opinions? I am perfectly fine taking even longer to make sure we aren't being too hasty.

[martinfleis]

There's no rush. I'd wait for the next dev call next week.

[jGaboardi]

The dev team in attendance at the 2023-12-7 meeting voted in favor of this implementation. Shall we go ahead and merge now or would it be better to wait longer?
