Semantic highlighting doesn't work with `coc-clangd` on `nvim`

CodePurble commented 3 years ago

Description Semantic highlighting with coc-clangd is not working. The default nvim syntax highlighting seems to be taking over. No symbols are detected by the plugin for highlighting.

To Reproduce

Install coc.nvim
Install coc-clangd
Install clangd from standard repos
- In my case, I did sudo pacman -S clang
- which clangd returns /usr/bin/clangd, which is in my PATH
Generate compile_commands.json and open a source file

Expected behavior Semantic highlighting for structs and classes

Additional context I was previously using the stock builtin LSP for nvim v0.5.0. I then switched to coc-clangd. I have used this before, and it had worked. I've also attached the coc.nvim logs for reference.

Seems like nvim-lsp is overriding coc.nvim from the logs. I can also confirm that the experience is similar with nvim v0.4.4, so I'm not sure whether nvim-lsp is the culprit.

It's a coc.vim / coc-clangd problem. clangd/coc-clangd#287

CodePurble commented 3 years ago

I see. I guess I'll have to roll back my coc.nvim for now. Have you found any other workaround?

CodePurble commented 3 years ago

Since this is a problem with coc-clangd, I'm closing this issue.
