# LSP with lazy.nvim

I was struggling a lot to set up LSP with lazy.nvim. There was the nvim-lspconfig, the nvim-cmp (for pop-up window), mason.nvim for easy install, and none-ls (previously null-ls).

I had lsp-zero in my old config, and in lazy.nvim, I tried several setups to put it in different config = function() blocks.

As I might guess, others are struggling too, the video and especially the dotfiles from Josean Martinez just solved it for me. I saw he skipped lsp-zero with lazy and I could understand how to set up.

I ended up copying his setup and just replacing it with my shortcuts and configs. Here are the most important parts which were important to me.

Add an lsp folder to lazy.lua (replace josean with your name)

1

require("lazy").setup({ { import = "josean.plugins" }, { import = "josean.plugins.lsp" } }, {

1. Add a nvim-cmp.lua for proper auto-compmlete, see dev-environment-files/.config/nvim/lua/josean/plugins/nvim-cmp.lua at main · josean-dev/dev-environment-files · GitHub
2. Copy his lsp folder and check what he is doing. notice there is no lsp-zero (not sure if that can still be used?)
   1. I enjoy that in lspconfig.lua, he configures, each language server is configured manually, as this gives a sense of control that I missed before when I just assumed it would work (but probably didn’t all the time).
   2. ensure_installed with the installed packages you want can be configured easily in mason.lua
   3. and setting for linting can be set in one place under none-ls.lua .

After I copied his configs and commented out mine, it just worked. So I could simply replace his shortcuts and configs with mine, and it just worked, and my frustration went back to joy. I have no agenda to promote his content, but just to help others who might struggle too.

Also, a nice side effect: my startup time (Neovim StartUp Times) went through the roof and starts now in 76 ms, even with 82 plugins 🙈. I hope that helps; my LSP configs I ended up with can be found in my dotfiles, too.

One thing I couldn’t figure out was the format on save; didn’t work for me in Python. I had this before that worked:

1
2
3
4
5
6
7

Show autodiagnostic popup on cursor hover_range
vim.cmd([[
" Python: auto format on save with Black
autocmd BufWritePre *.py execute ':Black'
" set virtual env -> still needed with lsp? 
let g:python3_host_prog = expand($HOME."/.venvs/nvim/bin/python3")
]])

But I was hoping to include it in the none-ls.lua in on_attach function. If anyone has a hint, it would be super appreciated.
