LanguageClient-neovim VS nvim-lspconfig

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.

I suggest looking for blog posts about this, you're gunnuh wanna pick out a plugin manager and stuff. It's kind of like a package manager for neovim. You can install everything manually but usually you manually install a plugin manager and it gives you commands to manage the rest of your plugins.

These two plugins are the bare minimum in my view.

Treesitter gives you much better syntax highlighting based on a parser for a given language.

https://github.com/neovim/nvim-lspconfig

This plugin helps you connect to a given language LSP quickly with sensible defaults. You more or less pick your language from here and copy paste a snippet, and then install the relevant LSP:

For Python you'll want pylsp. For JavaScript it will depend on what frontend framework you're using, I probably can't help you there.

pylsp itself takes some plugins and you'll probably want them. https://github.com/python-lsp/python-lsp-server

Best of luck! Happy hacking.

Adding language support it neovim isn't very difficult once you're setup. I use nvim-lspconfig[1] and just about any language you could need is documented[2]. But like others have mentioned there are batteries included distributions of neovim if that's your cup of tea.

If we can't find the basic usage in the documentation we can go to nvim-lspconfig's github repository. In there we look for a folder called server_configurations, this contains configuration files for a bunch of language servers.

https://github.com/hrsh7th/nvim-cmp This is an autocompletion engine https://github.com/nvim-treesitter/nvim-treesitter This allows NeoVim to install parsing scripts so NeoVim can do things like code highlighting. https://github.com/williamboman/mason.nvim Not strictly necessary, but allows you to access a repo of LSP, install them, and configure them for without you actively messing about in config files. https://github.com/neovim/nvim-lspconfig Also not strictly necessary, but vastly simplifies LSP setup. https://github.com/williamboman/mason-lspconfig.nvim This lets the above two plugins talk to each other more easily.

This specific issue talks about fixing clangd for that error: https://github.com/neovim/nvim-lspconfig/issues/2184. The issue is ongoing for ccls AFAIK but for clangd, this has been discussed and fixed in the past already.

I am trying to set up the pbkit language server for protobuf files. Since it is not part of the nvim-lspconfig repo's server configurations, I have to figure the way out myself. It doesn't seem to be too difficult, as I can start from the bufls configuration there. The following is what I have at the moment:

I have configured neovim with lspconfig and mason. Added the suggested configuration of the lsp config(https://github.com/neovim/nvim-lspconfig) to ~/.config/nvim/after/plugin/lsp.lua Then I installed via mason the following language servers:

Personally, i think nvim-lint is the best alternative currently, specially so because it has no dependencies on external binaries. This guide assumes you already have your LSP set up with nvim-lspconfig (or an alternative like lsp-zero). You should also have an way to install the linters you are gonna need, i highly recommend Mason with mason-lspconfig.

Basically neovim can act as a client to a variety of different language servers (https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...) which give neovim IDE capabilities. This can be done in original Vim also but requires external plugins which can be a pain to compile and install. Neovim has it built in.

I'm struggling to get [sqlls](https://github.com/joe-re/sql-language-server) with [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) to use Postgres syntax.
