VS Code Intellisense not working #112

Open mozark24 opened 7 years ago

mozark24 commented 7 years ago

Following the "Setup guide" (if one can call it that) as closely as possible and I cannot get the intellisense to correctly work on VS Code. I get "Loading" hovering the mouse over words. Really think the install procedures could use some cleaning up... Any suggestions?

Try set ocaml.merlinPath to a full path. I guess your merlin not exists in your $PATH.

mozark24 commented 7 years ago

I double checked my path (both in Cygwin, and in VSCode) At the top of my $PATH:
/home/User/.opam/4.05.0+mingw32c/bin In VSCode settings overwriting default:
"ocaml.merlinPath": "G:/OCaml/home/User/.opam/4.05.0+mingw32c/bin/ocamlmerlin"

I also tried substituting \\ for / to no avail. Can you post yours as example?

Your config is correct.

My OS is macOS. I'll check it in windows VM later. If you'd like to get it work in a hurry, and you know typescript. You can debug ocaml extension to figure out what's wrong.

Copy. Thank you for your assistance and assurance. I do not know typescript and I'm about ready to head to bed for the night. Will check-in later.

This is likely a bug on Windows OS of merlin 3.0.2.0, I've tested ocaml 4.05.0+mingw64c + merlin 3.0.2.0. It doesn't work, too. If you execute ocamlmerlin in cygwin's terminal, it will stuck the terminal.

I've tested ocaml 4.04.2+mingw64c + merlin 2.5.5. It works properly. For now, you can switch to 4.04.2 on Windows OS to use vscode-ocaml.

I'm also having some issues after switching to OCaml 4.05.0+mingw64c. This message appears in the dev console a lot:

Everything was working great with OCaml 4.02.3.
