JFYI, we should be able to generate from Menhir grammar list of sentences to cover tricky cases (for instance all automaton transitions involved in a conflict).

It is not only open, it is all top-level definitions. The problem has to do with how merlin selects the environment when the definition under the cursor is not parseable....

I had the same problem using dune 3.4.1 in a project using `(lang dune 2.7)` with non-ppx preprocessors (using this specification: https://dune.readthedocs.io/en/stable/concepts.html?highlight=per_module#per-module-preprocessing-specification)

No. My filter is a simple CPP-like text processor that removes some chunks of code (based on OCaml version).

It seems that even correct code is generating overlapping locations, both with Merlin and OCaml parsers: ```oaml let () = (Foo.Bar.());; ``` ``` [ structure_item (test.ml[1,0+0]..[1,0+21]) Pstr_value Nonrec [ pattern...

Does ppxlib reject this?

So in the short term it is probably better to add this case to ppxlib.

Hi Darius, sorry for the late answer. Indeed, there is a mismatch, usually just at the node at the junction between Lwd and DOM. The commented line is meant to...

And thanks, I am glad that you like Lwd! I am really busy for now but I would like to give it some love in the next two years.

The history is not clean as it contains a previous implementation that just used an option (discussed in #11450). I can rewrite it if needed.
