There was a problem hiding this comment.
Enforcing a column limit has various idempotency issues. Usually minor, so no need to do sth immediately, but something to keep in mind if it gets too annoying.

Would you rather suggest to reformat the code base and to not enforce the limit? I do not see how we would be able to prevent addition of longer lines in this case.

No, what you do in this PR looks good to me, just pointing out this potential downside of column-limit, but no immediate action required.

fourmoluto the Nix shellscripts/ci/run-fourmolu.shscripts, which is based on the previously used script forstylish-haskellfourmolu(and pushed a dummy commit to check that the CI rejects improperly styled code).git-blame-ignore-revsand checked that the blame interface on GitHub respects itfourmolu.Additionally, I've enabled
ImportQualifiedPostin all cabal files, alongside with the-Wprepositive-qualified-modulewarning. This extension and warning could be removed once (if?) we transition toGHC2021as the default language.
