git clone https://github.com/actionshrimp/lsp-dune-test-repo
cd lsp-dune-test-repo
opam switch create . --empty
opam switch set-invariant ocaml-base-compiler.4.12.1
opam install ocaml-lsp-server dune
opam exec -- dune build
At this point ocaml-lsp doesn't seem to like symbols in vendor/inner-a/src/inner_a_main.ml. Inside vendor/inner-a/src/inner_a_lib.ml I get this error message:
No config found for file "inner_a_lib.ml" in "src". Try calling `dune build`.
However, the Inner_a reference from src/lib.ml functions correctly.
If you rename vendor/inner-a/dune-workspace to dune-workspace.bak, restart the LSP process, and run dune build again, everything seems to function as expected.
Add another dune-workspace at the repo root.
