clangd VS LanguageClient-neovim

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.

i know the language client neovim has such a function (:help languageclient_textdocument_codelens after compiling its helptags). AFAIK you can get that running in Vim 8, but not sure.

On NeoVim, the built-in LSP client works without modification. On Vim, you will need LanguageClient-neovim.

I'm using LanguageClient-neovim. Here's the relevant portions of my init.vim:

I just saw a nice post in /u/medwatt about using vim for VHDL/Verilog and thought I'd contribute a little! * Syntax and error highlight: https://github.com/autozimu/LanguageClient-neovim * Column align: https://github.com/junegunn/vim-easy-align * Remove annoying whitespaces: https://github.com/ntpeters/vim-better-whitespace * Partial (fuzzy) filename search: https://github.com/junegunn/fzf.vim * Outline all declarations inside a file: ⠀https://github.com/preservim/tagbar * Treat indentations as vim-objects (useful for languages that don't use { }): https://github.com/michaeljsmith/vim-indent-object There is also mouse support in vim for those who want it. Try typing :set mouse=a. Very useful for resizing windows. I also highly recommend you get good at using folds (https://vim.fandom.com/wiki/Folding). It makes it a LOT easier to navigate files. You can save your fold config per-file with :mkview and load it later with :loadview. If I come up with more hints - I'll mention them in the comments!

I've been using LanguageClient and solargraph gem with plain Vim 8 for a long time already. Still, having a bit better experience at Ruby coding with Emacs and its lsp-mode & company & inf-ruby combo.

Might migrate to Neovim's native LSP support at some point, however I find vim-lsp more feature complete out of the box. I used to use LanguageClient-neovim, however, I missed proper support for signature help.

YCM is a client. The client is a plugin for Vim or Neovim, even the "built-in" client in Neovim is just a Lua plugin that is included with the editor, it's not really built-in. Examples of other clients:LanguageClient-neovim, vim-lsp, ale.

LanguageClient-neovim just merged some support for semantic tokens and the plan, as I read the PR/issues, is to next implement some default mappings from the semantic tokens to highlight groups.

The best LSP client is the one that works for you. When it comes to neovim, there is a generous variety of LSP clients to choose from. The notables ones being vim-lsc and vim-lsp written in vimscript, LanguageClient-neovim written in rust, YouCompleteMe is written in python and in my experience is the hardest to install, coc.nvim written in typescript and, of course, the neovim's built-in one. I would recommend going with coc.nvim, as it is the best LSP client right now, though it provides much more features than a standard lsp client does and for some people it is a disadvantage and for the others it's not. Also you have to install node.js on your system for coc.nvim to work. I myself use neovim built-in one for a few reasons: it's not in stable yet, but when the neovim 0.5 version comes out, it is gonna be the standard client. Another reason is it's extremely lightweight and customizable. There were already several discussions on the subreddit about the clients you can check out.
