Set different line-length for .py and for .ipynb

[arogozhnikov]

Hi ruff team, I'd like to set much longer line-length for notebooks (than regular python files), but can't find the right way to do it.

There is a way to switch off max line-width rule in linter, but I want to use formatter on notebooks (with larger line-length).

hi @arogozhnikov

I don't think there's a way to configure this today unless your notebooks and regular python files are stored in different directories. If your notebooks are in a different directory, you can then create a ruff.toml in that directory, set extend = <root_config.toml>, and override format.line-length.

unfortunately they aren't - notebooks have some associated scripts in the same folder.

Formatting for notebooks looks very helpful, but for now I have to switch it off :/

I would like to be able to do this as well (in our case, to use a shorter line length in Jupyter notebooks). It seems like a fairly obvious feature, since the user environment is so different between .py and .ipynb.

Thanks!
