Is it possible to enable type completion in Typerex for external modules? In particular I am trying to use js_of_ocaml.
I can see local identifiers in code completion, so it is definitely enabled, but when I type (for example) Dom_html. I don't get a list of the module's contents.
Version 1 of TypeRex does not provide completion on files with syntax extensions, unless you play some tricks with camlp4.
Version 2 of TypeRex will work better, as it will based on a relaxed syntax of OCaml, and usually most standard syntax extensions are compatible with this relaxed syntax.
Version 2 is not yet released, but you can still try it in the branch typerex2 of the repository.
