Neovim is a highly extensible and open source text editor that aims to improve upon and modernize the popular Vim editor. It's designed to be a drop-in replacement for Vim, maintaining compatibility with most Vim plugins and configurations while offering additional features and improvements. Neovim focuses on extensibility, usability, and performance.

It introduces a powerful plugin architecture that allows for asynchronous plugin execution, which can significantly improve performance for certain operations. It also includes a built-in terminal emulator, allowing users to run shell commands directly within the editor. The project emphasizes code quality and maintainability, with a clean, well-documented codebase that makes it easier for developers to contribute.

インストール

nix-shellを使う

To temporarily use Neovim in a shell environment without modifying your system configuration, you can run:

$ nix-shell -p neovim

This makes the Neovim editor available in your current shell. You can then launch Neovim by typing nvim.

System setup

To install Neovim system-wide, making it available to all users, add the following to your configuration:

<span lang="en" dir="ltr" class="mw-content-ltr"># Example for /etc/nixos/configuration.nix</span>
environment.systemPackages = [
  pkgs.neovim
];

<span lang="en" dir="ltr" class="mw-content-ltr"># User-specific installation (in ~/.config/nixpkgs/home.nix)</span>
home.packages = [
  pkgs.neovim
];

After rebuilding your system with nixos-rebuild switch or home-manager switch, Neovim will be installed and accessible.

Plugin Management

  }

  <div lang="en" dir="ltr" class="mw-content-ltr">

Frameworks

If you prefer not to configure your system manually, NixOS offers several predefined configurations and community-supported options. Here are a few of them:

• LazyVim
• AstroNvim
• NVChad

LazyVim, by default, will prevent loading plugins that are not managed by LazyVim. This includes all plugins installed via Nix. If you want to install plugins with both Nix and LazyVim, add the following to your LazyVim setup:

require("lazy").setup(lazyPackages, {
   performance = {
     reset_packpath = false, -- so that plugins outside of lazy can be loaded
   },
 })
 vim.cmd([[ packloadall]] ) -- load plugins outside of lazy

Source

FHS wrapper

You can create a custom neovim FHS wrapper

{
  buildFHSEnv,
  writeShellScript,
  neovim,
}:
buildFHSEnv {
  name = "nvim-fhs";
  targetPkgs = pkgs: [ neovim ];

  runScript = writeShellScript "nvim-fhs.sh" ''
    exec ${neovim}/bin/nvim "$@"
  '';
}

This FHS wrapper example is based on a contribution to nixpkgs. For an extended configuration that includes setting up mason.nvim with a similar FHS environment, see this NixOS/nixpkgs issue comment.
