Support for legacy code base - baseline

[Pixel-Minions]

Hi,

Thank for such a cool tool.
I am currently working with a huge monolithic old code base. I am planning to use a linter like ruff with only new code, so I don't have old errors appearing in thr console. It is possible to create a baseline so only the new code gets lint?

Thank you :)

I think this is a duplicate of #1149. Unfortunately, it's not something we support right now -- maybe some day. The only alternatives you would have are (1) running ruff check --add-noqa /path/to/src to automatically add suppression comments to existing violations, or (2) only enabling a subset of checks for now, and fixing all violations for that subset.

(I do empathize with this need and acknowledge that we don't have a great solution for it right now.)
