Is it possible to get type checking for ocamllex .mll files?

[anentropic]

When working on a .mll file I don't get any of the between-lines type hints (Code Lens?) that I get when editing a regular .ml file

Would be really handy if that was possible

It would indeed be handy. But this plugin is completely dependent on merlin to provide this functionality, so there's not much we can do. We can ping @let-def so that he perhaps can keep this issue in the back of his mind meanwhile.

I have a POC implementation of ocamllex support in this branch https://github.com/ocaml/merlin/tree/lex-n-yacc
I would like to add menhir/yacc support at some point in the future... But I have no idea when I will have the time.

oh that's great news 🎉

I only need ocamllex... :)
