Neovim and Lua

May 19, 2021

Recently I came across several posts that discuss the use of Lua for the Neovim init file, as well as the new trending packages that everyone will be using in a few months for LSP-related stuff. In fact, the very first hit was the config written by Seth Brown, that whetted my curiosity. I decided to try it on my Mac since I have Node installed on it, and it was pretty nice, except for the startup time: my Neovim is up and running within 50 ms or so (with only 16 plugins, managed by Plug) while all those new plugins require more than 200 ms to be fully initialized. This should probably be less on my Linux machine since it is faster than my Macbook. Still, it is a bit higher than I would like. That being said, here are the essential plugins that Seth Brown requires in his setup:

We talked about LSP and Vim in a recent post, but this time this all about Neovim built-in LSP client. I haven’t changed my mind since then, and I prefer to write like a zoombie, with good linters at hand (thanks to Ale) and a little help from omnicompletion from time to time. I learned (the hard way?) that it’s better to type, erase and write again, rather than copy/paste blindly.

Finally, a special mention to gitsigns, which could replace vim-gitgutter (same functionalities, with additional blaming support), and lualine.nvim as a lightweight replacement for airline.1 All of the above require Neovim 0.5+, of course. If you’re curious, there’s also this collection of awesome Neovim plugins. I’m still on Neovim 0.4.3 because this is the LTS version according to Ubuntu package manager. I don’t mind, I used to use the nightly build for several months in the past, but I found it annoying to upgrade to new Git release after every apt update. I could even use Vim 8 only, but I like how Neovim makes using a terminal alongside opened buffers so smooth. I now stand by well curated packages, with few updates. Even my terminal emulator, Kitty, is probably outdated. I’ve seen my Emacs broke so many times in the past, due to package upgrades (or simply Doom update), that I prefer to live a few updates behind rather than spend a whole day fixing my day-to-day configuration

[2021-05-26]
I now use the latest release of Kitty, to maintain compatibility between my macOS and Ubuntu setup, but also because the Ubuntu stable release was mostly oudated. However, regarding Neovim I noticed that when switching to the nightly build the startup time increase from 60 ms to more than 100 ms, WTF? Apparently, it has to do with /usr/share/nvim/runtime/syntax/synload.vim, but I didn’t investigate much, and revert to v0.4.3. As I said in other posts, I don’t really need Lua config or LSP stuff.

  1. I wish I understand why plugins are sometimes prefixed with “vim” or “nvim”, while other plugins use suffixes instead. ↩︎
