This experimental branch does not yet bring many changes in the context of LSP… this is mainly for Merlin users (baremetal). LSP is the next step. however, we would be delighted to have an experience. I think the ‘right way’ to proceed would be:
# In the context of your project, in a local switch
opam pin https://github.com/ocaml/merlin#merlin-domains
opam pin add ocaml-lsp-server.dev https://github.com/ocaml/ocaml-lsp
Keep us posted and thank you for giving it a try!
