Yeah, I’m certainly open to improving the upstream defaults. Feel free to open issues with concrete suggestions, so we can discuss them in a more focused manner.

This morning I did a bit of a re-org of the font-lock defaults in neocaml, prompted by the discussion here. I haven’t addressed the specific issues we’ve been discussing, but I did notice that I actually hadn’t done some changes I thought I had already done… :sweat_smile:

In a nutshell:

  • Moved type from level 3 to level 2 and number from level 2 to level 3
  • Split escape-sequence out of string into its own feature at level 3
  • Split property (record fields) and label (labeled arguments) out of variable into their own features at level 4

New layout:

Level Features
1 comment, definition
2 keyword, string, type
3 attribute, builtin, constant, escape-sequence, number
4 operator, bracket, delimiter, variable, property, label, function

Now the defaults are actually aligned with the official Emacs suggestions, and the features are more granular and more aligned with what an OCaml programmer might want to font-lock differently.

FYI - Release v0.4.0 · bbatsov/neocaml · GitHub

You’ll need to update your Tree-sitter grammars due to some upstream (breaking) changes in the TS OCaml grammar.
