I was on your construct branch :-) But the issue persists after upgrading to 1.7.0: (new file, no build) > Since the user reported a specific merlin version, I think...

:-) There are a still few things I want to change before considering reviewing and merging that PR.

> @voodoos does #5649 fix this? No, #5649 allows mode-dependent flags when building foreign stubs only, not ocaml flags.

@mshinwell @snowleopard: I was able to build the flambda-backend with this reimplementation of mode-specific foreign stubs The rebased "special-dune" which has a lot less patches than before is here: https://github.com/voodoos/dune/commits/special_dune...

This PR is now ready for review: only the docs update is missing. A lot of the code addition goes into the `Mode.MultiDict` data-structure that is a bit heavy but...

I probably won't...

Thanks for your precise report. We indeed dropped support for the `-package` flag and thus the `merlin-use` feature when moving to external configuration reader. The recommended way to indicate packages...

One of the reasons for using external configuration readers was to make the core of Merlin free of its ocamlfind dependency and this feature also depended on it. However I...

The last release of Merlin introduce a new editor-side "merlin use" commands by @def. Can you confirm if these answer to your use cases ? > Merlin used to support...

I am surprised because Menhir is not at all a dependency of Merlin when building in release mode: the MenhirLib that is used when we don't regenerate the parser is...
