python-lsp-server VS completion-nvim

Python LSP Server works great, is easier to install and even offers some optional extensions.

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.

I came at the tail end of https://github.com/python-lsp/python-lsp-server/issues/195. The possibility of me sponsoring a fix came up, and I’m on board with it, but the other contributor never replied.

I haven't used pylint, but I find mypy with python-lsp-server extremely easy to use with nvim-lspconfig, especially on Arch linux.

Whatever you use, make sure you have syntax highlighting, completion and error checking! I'm using pylsp and shellcheck in emacs, but those or similar options should work in any IDE, replacing much of what made IDEs unique in former times.

Perhaps unrelated, from my experience, pylsp is better than pyright, see https://github.com/python-lsp/python-lsp-server/.

I am finally starting to use lsp for python development. I am using pylsp as LS.

I'm talking about this python LSP server (the command is pylsp that's why).

Another example, you can setup python-lsp-server with nvim-lspconfig (lsp server also needs to be installed globally or in virtualenv) and they have a plugin for black which you can then install in the same virtualenv and just use lsp to format the code instead of formatter.nvim.

Do you use any lsp (like pylsp or pyright)? If yes, did you setup it to use proper python / did you activate venv?

I think it can be on any lua file. Plus I checked completion.nvim is now on archived.

You don't, nvim-cmp sets up you. Jokes aside, I am using completion-nvim. Unfortunately it got abandoned just as Neovim 0.5.1 got released, which contained a breaking change. You can look into the pending PRs to see how to fix it for yourself, just use one of the fixed forks. It really sucks, but unless someone steps up an creates a new completion plugin that's what I am stuck with.

I couldn't figure out how to change this. I found some options, some of which made an entire split window appear above... that's hideous. I also found this, but that works with lua. How do I even set up these lua scripts? I don't get it. Can I get some guidance? Thanks.

I have tried to move to nvim-cmp since completion-nvim is dead, but for the life of me I cannot figure out how to make it not automatically select the first completion candidate. If I type date and hit to insert a new line, cmp takes as the "confirm selection" key (because I have mapped it that way) and expands the snippet. I only want to confirm a selection if I actually selected something from the menu. completion-nvim may be dead, but at least its author had the courtesy to write down how to use it in complete plain English sentences instead of broken English one-liners. Eventually I gave up and moved back to the old setup.

That will give you the basics, you should see linter diagnostics and auto omin completion should work. For better auto-completion and snippets you can set up one of the completion- and snippets plugins. Personally I use completion-nvim and Ultisnips. There may be better plugins out there, that's just what I happen to have installed.

I recently upgraded from Neovim 0.5.0 to 0.5.1 and LSP autocompletion stopped working. I'm using https://github.com/nvim-lua/completion-nvim but it looks like its maintenance could be much better. I'm looking for some alternative but I'm not sure what would be a good choice for LSP. Any recommendations?

I'm trying to configure completion-nvim with Neovim's LSP, but am not getting any sort of pop-up/display.
