Scalafix test failing on Windows due to CRLF line endings?

[Piyush-t24]

Hi! I'm exploring the Feral repo.

While running the tests on Windows, I noticed one scalafix rewrite test failing (RuleSuite / V0_3_0Rewrites.scala). After digging a bit, it seems related to line endings: the repo currently doesn’t have a .gitattributes file, and with core.autocrlf=true Git checks files out as CRLF on Windows. Since scalafix rewrite tests compare snapshots, the mix of CRLF input and LF output can introduce extra blank lines in the obtained result.

I also noticed that several Typelevel repos don’t have a .gitattributes file, so contributors working on Windows might run into similar issues.

Do you think adding a .gitattributes (e.g. enforcing LF for Scala/sbt sources) would be a good approach for cross-platform compatibility, or is there another recommended way to handle this?
