LanguageClient-neovim VS vim-lsp

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.

Has anybody managed or got an idea how to make SonarLint Language Server work with e.g. vim-lsp?

You need to configure a language server. For C++ it's a bit tricky, so good luck with Go. There are other plugins that provide semantic highlighting using LSP, for example https://github.com/prabirshrestha/vim-lsp (I didn't try it, but it seems good).

ALE can use LSP as well. And if you are using vim-lsp, you can use the same instance of server for both with vim-lsp-ale bridge plugin.

I feel the same way. Not a one-liner but the smallest config LSP plugin I've found is vim-lsp. It works in both Vim and Neovim.

The only major feature that Neovim still has is a built in LSP client. But I find the built in Neovim LSP client is unusably buggy, you're much better off using any of the other LSP plugins. What I use is vim-lsp, but I've tried all of the major lsp client, they are all significantly better than the built in Neovim LSP.

As for install/configuration, all you need is the latest Vim, the plugins I mentioned, and that bit in your vimrc. You can do a bit better than that if you copy the entire config with mappings from the vim-lsp GitHub page.

I have a problem with Deoplete and Vim-LSP completion (Python's Pylsp and Jedi-Language-Server). The suggestion is much less, and it also misses a lot of opportunities to suggest compared to Deoplete-Jedi, which literally defeats the former by a large margin. Is there a setting to make this duo works like deoplete with deoplete-jedi?

- add the [prabirshrestha/vim-lsp](https://github.com/prabirshrestha/vim-lsp) plugin and config to your `.vimrc` (note: `pylsp` is *not* necessary).
