ccls VS emacs-ccls

Then it would just have a dependency on Clang, and you couldn't use Emacs at all (since you can't use Clang).

AFAIK, the only alternative to the clangd language server is ccls: https://github.com/MaskRay/ccls

The base config adds about 15 lines (I have extra settings adding another 15 lines), then each language server adds a few lines per augroup. Example config for ccls.

Try ccls instead, it has setup instructions for many LSP clients in the wiki: https://github.com/MaskRay/ccls

vim-lsp and ccls, supertab for auto-completion

these days a good lsp plugin will get you 90% of what you need for most languages and codebases. once youve got that set up its just a matter of picking lsp servers. i use ccls for c/c++. if you set it up and its not giving you hints for godot classes you probably have to point ccls at the proper godot-cpp subdirs using a .ccls file in your project root.

I installed ccls using snap for ubuntu.

C++/C language server: ccls

ccls: https://github.com/MaskRay/ccls/issues/798

ccls with lsp-mode and dap-mode and is what will fill most of those needs.

I haven't written any decent elisp code for ~3 years now and admittedly I have forgotten the little elisp knowledge I used to have. Upgrading doom-emacs has been a challenge for me as I'd be difficult to deal with possible breakage. (Also, sorry to admit that but I have also shifted some editor usage to neovim.) I am not able to properly maintain https://github.com/MaskRay/emacs-ccls anymore. There has been a few client-side issues I would probably never know how to address.

I've broken into emacs backtrace with kill -USR2 and I've dumped the lsp io log, and what I can tell is that there's no communication between ccls and emacs when the hang happens. This isn't a case of ccls flooding emacs. The backtrace shows that its hanging on this line of ccls-mode: https://github.com/MaskRay/emacs-ccls/blob/master/ccls-semantic-highlight.el#L304 Specifically its hanging inside that call to find-buffer-visiting in some tramp internals. What I'm wondering is, is ccls-mode misusing this call? Or is something broken in tramp?
