[https://neovim.io/ Neovim]<ref>Neovim Team, "Home - Neovim", Neovim Official Website, Last updated March 2025, Accessed June 2025. https://neovim.io/</ref> is a highly extensible and open source text editor that aims to improve upon and modernize the popular [[Vim]]<ref>NixOS Wiki Community, "Vim", NixOS Wiki, Last edited 24 February 2025, Accessed June 2025. https://wiki.nixos.org/wiki/Vim</ref> 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.


== Installation ==
<!--T:2-->
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.


=== With Home Manager ===
== Installation == <!--T:3-->


[[Home Manager]] has a module for Neovim, which can be enabled via
==== Shell ====


<syntaxhighlight lang="nix">
To temporarily use Neovim in a shell environment without modifying your system configuration, you can run:
programs.neovim = {
{{code|lang=bash|line=no|1=$ nix-shell -p neovim}}
  enable = true;
This makes the Neovim editor available in your current shell. You can then launch Neovim by typing <code>neovim</code>.
  extraConfig = ''
    set number relativenumber
  '';
};
</syntaxhighlight>


More information about the module can be found here: [https://nix-community.github.io/home-manager/options.xhtml#opt-programs.neovim.enable Home Manager Manual].
==== System setup ====


=== System-wide ===
To install Neovim system-wide, making it available to all users, add the following to your configuration:
{{code|lang=nix|line=no|1=# Example for /etc/nixos/configuration.nix
environment.systemPackages = [
  pkgs.neovim
];


If you do not use Home Manager, you can use the following code in your NixOS configuration:
# User-specific installation (in ~/.config/nixpkgs/home.nix)
home.packages = [
  pkgs.neovim
];}}
After rebuilding your system with <code>nixos-rebuild switch</code> or <code>home-manager switch</code>, Neovim will be installed and accessible.


<syntaxhighlight lang="nix">
programs.neovim = {
  enable = true;
  defaultEditor = true;
};
</syntaxhighlight>


You can also manually add Neovim to your packages. This should only be used if the two version above do not work for you.
== Configuration == <!--T:7-->


<syntaxhighlight lang="nix">
==== Basic ==== <!--T:8-->
environment.systemPackages = [ pkgs.neovim ];
</syntaxhighlight>


== Configuration ==
</translate>
 
{{code|lang=nix|line=no|1=<translate>
Neovim shares most of its configuration with Vim. See the [[Vim|Vim page]] for more details on the use of both.
<!--T:39-->
 
# Global Configuration
=== With Home Manager ===
</translate>
 
The Home Manager module does not expose many configuration options. Therefore, the easiest way to get started is to use the [https://nix-community.github.io/home-manager/options.html#opt-programs.neovim.extraConfig extraConfig] option.
You can copy your old config or directly load your default Neovim config via:
 
<syntaxhighlight lang="nix">
programs.neovim.extraConfig = lib.fileContents ../path/to/your/init.vim;
</syntaxhighlight>
 
To use Neovim as your default editor, you can set the <code>EDITOR</code> [https://search.nixos.org/options?show=environment.variables&type=packages&query=environment.variables environmental variable] to "nvim" by adding the following to your NixOS configuration:
 
<syntaxhighlight lang="nix">
environment.variables.EDITOR = "nvim";
</syntaxhighlight>
 
The Home Manager module does also expose options to automatically add <code>vi</code> and <code>vim</code> aliases.
To use them, add the following to your Home Manager configuration:
 
<syntaxhighlight lang="nix">
programs.neovim = {
programs.neovim = {
  viAlias = true;
  enable = true;
  vimAlias = true;
  defaultEditor = true;
};
};
</syntaxhighlight>


==== Installing Plugins ====
<translate>
<!--T:40-->
# Home Configuration
</translate>
programs.neovim = {
  enable = true;
  extraConfig = ''
    set number relativenumber
  '';
};}}
<translate>


Plugins can be installed using the <code>programs.neovim.plugins</code> option.
==== Advanced ==== <!--T:10-->
You can add only the plugin, or the plugin with its corresponding config:


<syntaxhighlight lang="nix">
</translate>
programs.neovim.plugins = [
{{code|lang=nix|line=no|1=<translate>
  pkgs.vimPlugins.nvim-tree-lua
<!--T:41-->
  {
# Global Configuration
    plugin = pkgs.vimPlugins.vim-startify;
</translate>
    config = "let g:startify_change_to_vcs_root = 0";
  }
];
</syntaxhighlight>
 
If you only add the plugin, you can add the configuration as described above.
 
An index of official packages can be found in on [https://search.nixos.org/packages?from=0&size=50&sort=relevance&type=packages&query=vimPlugins search.nixos.org].
In addition to the official packages, there are several user maintained repositories, such as [https://github.com/m15a/flake-awesome-neovim-plugins vim-extra-plugins] or [https://github.com/NixNeovim/NixNeovimPlugins NixNeovimPlugins]. Plugins which are
not available in any of these repositories may be integrated using the <code>vimUtils.buildVimPlugin</code> function from Nixpkgs:
 
<syntaxhighlight lang="nix">
pkgs.vimUtils.buildVimPlugin {
  pname = "whatever";
  version = "whatever";
  src = builtins.fetchGit {
    url = "https://github.com/example/whatever.git";
    ref = "whatever";
  };
  buildScript = ":";
}
</syntaxhighlight>
 
=== System-wide ===
 
The NixOS module does not have an <code>extraConfig</code> option as the Home Manager module does.
Instead, you can use the <code>programs.neovim.configure</code> option as described [https://search.nixos.org/options?show=programs.neovim.configure&type=packages&query=neovim here].
 
The following example configures RC commands and enables the plugin <code>ctrlp</code> to support fuzzy file search (see [https://github.com/ctrlpvim/ctrlp.vim homepage] on how to use it)
 
<syntaxhighlight lang="nix">
programs.neovim = {
programs.neovim = {
   enable = true;
   enable = true;
  defaultEditor = true;
  viAlias = true;
  vimAlias = true;
   configure = {
   configure = {
     customRC = ''
     customRC = ''
Line 122: Line 101:
   };
   };
};
};
</syntaxhighlight>


To set Neovim as your default editor:
<translate>
<!--T:42-->
# Home Configuration
# You have to add the line below to set it as the default editor:
</translate>
environment.variables.EDITOR = "nvim";}}

==== Package Variations ==== <!--T:15-->


<syntaxhighlight lang="nix">
Have a look at the [https://github.com/nix-community/neovim-nightly-overlay Neovim Nightly Overlay]<ref>Nix Community, "neovim-nightly-overlay", GitHub, Last updated June 2025, Accessed June 2025. https://github.com/nix-community/neovim-nightly-overlay</ref> to install the most recent current nightly version of Neovim.
programs.neovim = {
You can run the master version via the following command:
  defaultEditor = true;
{{code|lang=bash|line=no|1=$ nix run "github:nix-community/neovim-nightly-overlay"}}
};
 
</syntaxhighlight>
==== Plugin Management ==== <!--T:21-->
 
</translate>
{{code|lang=nix|line=no|1=plugins = [
<translate>
  <!--T:49-->
# Example Plugin: nvim-tree-lua
</translate>
  pkgs.vimPlugins.nvim-tree-lua

</translate>
  {
    plugin = pkgs.vimPlugins.vim-startify;
    config = "let g:startify_change_to_vcs_root = 0";
  }


Further, the NixOS module does also expose options to automatically add <code>vi</code> and <code>vim</code> aliases.
<translate>
To use them, add the following to your NixOS configuration:
  <!--T:51-->
# Example Plugin: nvim-colorizer-lua with Lua config
  # Due to how the runtimepath for Lua modules is processed, your configuration may require
  # packadd! plugin-name to require a module. A home-manager example:

  {
    plugin = pkgs.vimPlugins.nvim-colorizer-lua;
    config = ''
      packadd! nvim-colorizer.lua
      lua << END
        require 'colorizer'.setup {
          '*';<translate> <!--T:52--> -- Highlight all files, but customize some others.</translate>
          '!vim';<translate> <!--T:53--> -- Exclude vim from highlighting.</translate>
        }
      END
    '';
  }


<syntaxhighlight lang="nix">

programs.neovim = {
  <!--T:54-->
  viAlias = true;
# Example Plugin: nvim-treesitter with Lua config
  vimAlias = true;
</translate>
};

    plugin = pkgs.vimPlugins.nvim-treesitter;
    config = ''
      packadd! nvim-treesitter
      lua <<EOF
        require'nvim-treesitter.configs'.setup {
          highlight = {
            enable = true,              <translate><!--T:55--> -- false will disable the whole extension</translate>
            disable = {},              <translate><!--T:56--> -- list of languages that will be disabled</translate>
          },
          incremental_selection = {
            enable = true,
            keymaps = {
              init_selection = "gnn",
              node_incremental = "grn",
              scope_incremental = "grc",

=== Build Neovim using Nix ===
==== Frameworks ==== <!--T:18-->


You can also compile Neovim using nix. For this, the Neovim GitHub page has more information on this:
<!--T:45-->
[https://github.com/neovim/neovim/wiki/Building-Neovim#nixos--nix Neovim Guide].
If you prefer not to configure your system manually, NixOS offers several predefined configurations and community-supported options. Here are a few of them:


The Neovim repository also contains a flake.
<!--T:19-->
You can run the master version via the following command:
* [https://www.lazyvim.org/ LazyVim]<ref>LazyVim Team, "Getting Started", LazyVim Official Website, © 2025, Accessed June 2025. https://www.lazyvim.org/</ref>


nix run "github:neovim/neovim?dir=contrib"
<!--T:46-->
* [https://astronvim.com/ AstroNvim]<ref>AstroNvim Team, "AstroNvim", AstroNvim Official Website, N/A, Accessed June 2025. https://astronvim.com/</ref>


Finally, there is a [https://github.com/nix-community/neovim-nightly-overlay Neovim Nightly Overlay].

=== Note on Lua plugins  ===
<!--T:48--> ==== FHS wrapper ====


Due to how the `runtimepath` for Lua modules is [https://github.com/nanotee/nvim-lua-guide#a-note-about-packages processed], your configuration may require <code>packadd! plugin-name</code> to require a module. A home-manager example:
You can create a custom neovim FHS wrapper
{{code|lang=nix|line=no|1=
{
  buildFHSEnv,
  writeShellScript,
  neovim,
}:
buildFHSEnv {
  name = "nvim-fhs";
  targetPkgs = pkgs: [ neovim ];


<syntaxhighlight lang="nix">
  runScript = writeShellScript "nvim-fhs.sh" ''
programs.neovim = {
    exec ${neovim}/bin/nvim "$@"
  plugins = [
   '';
    {
      plugin = pkgs.vimPlugins.nvim-colorizer-lua;
      config = ''
        packadd! nvim-colorizer.lua
        lua << END
require 'colorizer'.setup {
   '*'; -- Highlight all files, but customize some others.
  '!vim'; -- Exclude vim from highlighting.
}
}
END
}}
      '';
 
    }
<!--T:FHS_WRAPPER_SOURCE-->
  ];
This FHS wrapper example is based on a contribution to nixpkgs<ref name="nixpkgs-pr-334032">NixOS, "Feature: Custom Neovim FHS Wrapper" (Pull Request #334032), GitHub, 2025, Accessed June 2025. https://github.com/NixOS/nixpkgs/pull/334032</ref>.
}
For an extended configuration that includes setting up `mason.nvim` with a similar FHS environment, see this [https://github.com/NixOS/nixpkgs/issues/281219#issuecomment-2284713258 NixOS/nixpkgs issue comment].

== Troubleshooting == <!--T:59-->
{{expand}}
 
==== lua-language-server: Dynamically linked executable error ====
 
In your <code>~/.local/state/nvim/lsp.log</code>, you have the following error:
 
{{code|lang=text|line=no|1=[ERROR][2025-06-07 23:13:15] ...p/_transport.lua:36 "rpc" "lua-language-server" "stderr" "Could not start dynamically linked executable: /home/incogshift/.local/share/nvim/mason/packages/lua-language-server/libexec/bin/lua-language-server\nNixOS cannot run dynamically linked executables intended for generic\nlinux environments out of the box.
