clangd VS ccls

I know one way to do this, but hoping there's something simpler or more general. clangd (C++ LSP server) is over-aggressive about adding "helpful" #includes during completion. The way to turn that off is to pass -header-insertion=never on its cmd line.

Install the clangd language server using your system package manager, e.g. sudo apt-get install clangd

> As a side note, I despise things like imports and aliases. I'd prefer that when I do jump to a function, I can read it without having to check if anything is imported or not.

One idea might be to use an LSP (Language Server Protocol) interface. It could describe the fully qualified symbol for you when you, say, select the abbreviated symbol or press a keyboard shortcut. I've been working on a moderately large C program with Emacs and clangd[1] recently and have been amazed at how 'immersive' it feels, and that's from someone who's used to the comfort of a Lisp REPL!

FWIW, recent clangd also has this feature: "unused" as of 14, "missing" as of 16, works better in snapshots.

You need to install CMake (and use it to build your project - which you should do in any case) and clangd.

First we would need the Clangd extension as well as the LSP itself You can download the extension from #here The extension provides its own Clangd LSP but in case of issues with that we would like to download and setup the clangd package from the official site for both Windows and Linux I daily drive Linux on my laptop, thus this guide works well for linux users, Windows users can use programs like Cygwin to replicate the process

Few days ago I found a bug while using clangd LSP with neovim, and submitted a bug report to clangd: https://github.com/clangd/clangd/issues/1640

Come to the light side: VSCodium with clangd

If you use the clangd LSP: https://github.com/clangd/clangd/issues

Overall I think it’s pretty good. Though I’ve found a nasty clangd bug might push me back to YCM. Though. I don’t recall this being a issue in my previous vim setup.

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.
