[Julow]

The aim of this preview is to gather feedback.

Changelog can be found here: https://github.com/ocaml-ppx/ocamlformat/blob/main/CHANGES.md

It looks like previously unformatted files are formatted (generated parser files in preprocess and sherlodoc). Is the due to the way you run the preview ?

[Julow]

I do dune build @fmt --auto-promote using dune 3.15.0 and I see these files being reformatted. Am I missing something ?

[voodoos]

Ah I see. It's an issue with Dune (or our config) that rebuilds the parser unexpectedly. Since your installed version of Menhir is not the same as the one the committed files are, there is a diff (which is unrelated to ocamlformat). We can simply ignore it for the purpose of the preview.
