Hello,

The NixOS community has been great in helping me with my first steps in this distro. So I’ll ask again few neovim-related issues I couldn’t figure out after 3 days of search.

First, let me tell you that I’m trying to import a working neovim setup from another distro. Then let’s see how I’ve configured neovim. I have this in my home.nix file:

programs.neovim = {
  enable = true;
  withPython3 = true;
  extraPython3Packages = (ps: with ps; [
    pynvim
    unidecode
    black
    isort
  ]);
  plugins = with pkgs.vimPlugins; [
    { plugin = *plugin_name*;
    type = "lua";
    config = builtins.readFile *config_file_path*;
    }
    ...
    ];
};

(my init.lua file is in the $HOME/.config/nvim folder)

With that most of my plugins work. Most because few are troublesome. Let’s focus on three of them:

  1. I have pkgs.vimPlugins.nvim-comment installed but neovim reports that the command CommentToggle is not an editor command

  2. I have pkgs.vimPlugins.nvim-treesitter installed but the command TSInstall markdown returns “could not create parser dir '/nix/store/…/nvim-treesitter/parser ': Vim:E739: read-only file system '”

  3. I have pkgs.vimPlugins.mason-nvim and pkgs.vimPlugins.mason-lspconfig-nvim installed but runngin checkhealth mason returns few warnings:

  • mason.nvim is not the latest version (I use the unstable channel)
  • pip: not available spawn: python3 failed with exit code 1 and signal 0. /run/current-system/sw/bin/python3: No module named pip (note that python3_host_prog and python3_host_prog pip are marked “OK”)

Thanks again for your assistance.

    Not sure about 1, but 2 and 3 both have the same answer. Both TSInstall and Mason are just trying to install other software packages on your system, and you’re on NixOS, so of course they can’t do that. You don’t install your software, you declare it. Add the Treesitter parsers you need right next to your plugins (there is a sub collection under the vimPlugins collection just for Treesitter parsers), and put whatever Mason would be installing into your user packages instead.

    That said, I agree with the other commenter. Even though the community has done a lot of work on rich config options for Neovim, they’re just too far away from the normal way of doing things in the Neovim world, and plenty of plugins are written in ways that assume it’s configured in “normal” ways. Plus configuring Neovim is already kinda like assembling your own car from parts in any case, so it’s honestly better to just use nix to install Lazyvim or whatever flavor of choice and let it handle the plugin management/config. And believe me, I really tried to do it all in Nix, I wanted to do it that way. But it’s just not worth the headache at this point

      Thanks for this feedback, it helps me feel a little bit less stupid :) With everything setup in NixOS documentation for neovim in appearance I thought really dumb to not be able to have it worked.

      Using the approach proposed by @flashgnash (i.e. using lazy.vim) let me install neovim and all my plugins.

      It’s also a nightmare if you want your config to work with both nix and non nix platforms. If I’m using my config on windows or at work, I’m not going to have nix and home manager to interpret the nix version of my vim config. On my systems with home manager, I’d like be able to install my nvim config as part of home manager rebuild. If I have home manager pull my configs git repo, it causes lazy to freak out whenever I try to update my plugins. It’d be nice to have some sort of integration with lazy that exists with cargo and similar tools but it doesn’t look like anyone’s been working on it.
