The only configuration setting in the file was the line length. Do you want to use the same setting with ruff?

[MaartenGr]

Thanks for the PR! I personally like having a bit longer line length to make certain code a bit more readable (like pandas operations). Having said that, I'm okay either way. Do you have a preference having seen the code in this repo?

[afuetterer]

I prefer longer line length as well. 80 or 88 like PEP8 or black recommend/enforce are too narrow for me.

I usually prefer 100 or 120. 160 might be too long. What do you think?

If you add

[tool.ruff]
line-length = 120

the ruff format --check . step in CI would fail, because ruff would reformat 30+ files.

Its your call, but as you asked me, I suggest 120.

Great, I had a feeling I wasn't the only one who liked a bit longer line length here. Let's do 120 since 160 was a bit of a stretch and 100 is too similar to what we have now.

[MaartenGr]

Great, LGTM! Should we also re-run ruff to deal with the increased line length or perhaps in a different PR?

[afuetterer]

I took the liberty to remove target-version = "py38" as well. As it is unneeded, when requires-python = ">=3.8" is defined. This is recommended by the ruff docs.

Re-ran ruff, lint job is passing.

[MaartenGr]

@afuetterer I just merged a PR that involves simplifying and improving the zero-shot topic modeling approach. It seems that that merge just created a bunch of conflicts for you, sorry!

[afuetterer]

Will fix those soon.

[afuetterer]

Rebased, re-ran ruff format on changed files.

[MaartenGr]

@afuetterer Great, thanks for the work on this!
