vscode-clangd VS ccls

Thanks for your reply, maybe I should go to vscode-clangd community to try to find out how they implement this:)

But I will say that I am mostly happy with either one of the clangd and ccls plugins. The clangd plugin is nicely packaged with a self-installer. The ccls plugin takes a little more work to set up, but it has loads more features. Both are quite good at working with a proper AST. Both build the AST by actually compiling your code with libclang (llvm's compiler core). Both work reliably for me because I am able to provide a compile_commands.json using my project builder (ninja). Nice as it is, it does not update automatically, and I'm not sure I want it to.

For C# there is https://github.com/muhammadsammy/free-omnisharp-vscode for Python there is https://github.com/Microsoft/pyright (Pylance is the proprietary counterpart) for C++ there is https://github.com/clangd/vscode-clangd

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.
