Nixvim is great. I got it configured with a flake and add it to all my machines. Nix lang is really suitable to composing neovim config.

Yup, I have a giant flake that configures all of my home linux and macos machines. Every machine gets more or less the same home-manager configuration applied, nixvim is split into its own flake.

I've been using the "old school" approach of just leveraging neovim + huge list of `vimPlugins` in my Nix config, makes you about the myriad of package managers for vim/neovim.

Replacing it with nixvim is on my forever growing todo list.
