may be done on any system that has the Nix package manager or the appropriate

extended library. This function will take <code class="literal">modules</code> and <code class="literal">extraSpecialArgs</code> as
arguments, and return the following schema as a result.</p><pre><code class="programlisting nix">{
options = &quot;The options that were available to configure&quot;;
config = &quot;The outputted configuration&quot;;
pkgs = &quot;The package set used to evaluate the module&quot;;
neovim = &quot;The built neovim package&quot;;

it with others. The next two chapters will detail specific usage of such a setup

If you are new to NixOS, I encourage you to look into Flakes and see if they fit
your use case. Alternatively, look into the aforementioned projects for more
convenient dependency management mechanisms.</p></div>

servers through the Nix module system. By default the LSP packages for relevant
language modules will be pulled into the closure. If this is not desirable, you
may provide <span class="strong"><strong>a custom LSP package</strong></span> (e.g., a Bash script that calls a command)
or <span class="strong"><strong>a list of strings</strong></span> to be interpreted as the command to launch the language
server. By using a list of strings, you can use this to skip automatic
installation of a language server, and instead use the one found in your <code class="literal">$PATH</code>
during runtime, for example:</p><pre><code class="programlisting nix">vim.languages.java = {
lsp = {
enable = true;
# This expects &#x27;jdt-language-server&#x27; to be in your PATH or in

Nix, sometimes doing things in Lua is simply the “superior” option. In such a
case you might want to configure your Neovim instance using Lua, and nothing but
Lua. It is also possible to mix Lua and Nix configurations.</p><p>Pure Lua or hybrid Lua/Nix configurations can be achieved in two different ways.
<span class="emphasis"><em>Purely</em></span>, by modifying Neovim’s runtime directory or <span class="emphasis"><em>impurely</em></span> by placing Lua
configuration in a directory found in <code class="literal">$HOME</code>. For your convenience, this
section will document both methods as they can be used.</p><div class="section"> <div class="titlepage"> <div> <div> <h2 id="sec-pure-nvf-runtime" class="title" style="clear: both">Pure Runtime Directory </h2> </div> </div></div><p>As of 0.6, nvf allows you to modify Neovim’s runtime path to suit your needs.
One of the ways the new runtime option is to add a configuration <span class="strong"><strong>located
relative to your <code class="literal">flake.nix</code></strong></span>, which must be version controlled in pure flakes
manner.</p><pre><code class="programlisting nix">{
# Let us assume we are in the repository root, i.e., the same directory as the
# flake.nix. For the sake of the argument, we will assume that the Neovim lua
# configuration is in a nvim/ directory relative to flake.nix.
vim = {
additionalRuntimePaths = [
# This will be added to Neovim&#x27;s runtime paths. Conceptually, this behaves
# very similarly to ~/.config/nvim but you may not place a top-level
# init.lua to be able to require it directly.
./nvim
];
};
}
</code></pre><p>This will add the <code class="literal">nvim</code> directory, or rather, the <span class="emphasis"><em>store path</em></span> that will be
realised after your flake gets copied to the Nix store, to Neovim’s runtime
directory. You may now create a <code class="literal">lua/myconfig</code> directory within this nvim
directory, and call it with <a class="xref" href="options.html#opt-vim.luaConfigRC" ><code class="option">vim.luaConfigRC</code></a>.</p><pre><code class="programlisting nix">{pkgs, ...}: {
vim = {
additionalRuntimePaths = [

</div><div class="section"> <div class="titlepage"> <div> <div> <h2 id="sec-impure-absolute-dir" class="title" style="clear: both">Impure Absolute Directory </h2> </div> </div></div><p>As of <a class="link" href="https://github.com/neovim/neovim/pull/22128" target="_top">Neovim 0.9</a>, <code class="varname">$NVIM_APPNAME</code> is a variable expected by Neovim to
decide on the configuration directory. nvf sets this variable as <code class="literal">&quot;nvf&quot;</code>,
meaning <code class="literal">~/.config/nvf</code> will be regarded as <span class="emphasis"><em>the</em></span> configuration directory by
Neovim, similar to how <code class="literal">~/.config/nvim</code> behaves in regular installations. This
allows some degree of Lua configuration, backed by our low-level wrapper
<a class="link" href="https://github.com/Gerg-L/mnw" target="_top">mnw</a>. Creating a <code class="literal">lua/</code> directory located in
<code class="literal">$NVIM_APPNAME</code> (“nvf” by default) and placing your configuration in, e.g.,
<code class="literal">~/.config/nvf/lua/myconfig</code> will allow you to <code class="literal">require</code> it as a part of the Lua
module system through nvf’s module system.</p><p>Let’s assume your <code class="literal">~/.config/nvf/lua/myconfig/init.lua</code> consists of the
following:</p><pre><code class="programlisting lua">-- init.lua

this</p><pre><code class="programlisting nix">{
# The attribute name &quot;myconfig-dir&quot; here is arbitrary. It is required to be
# a *named* attribute by the DAG system, but the name is entirely up to you.
vim.luaConfigRC.myconfig-dir = &#x27;&#x27;
require(&quot;myconfig&quot;)
-- Any additional Lua
&#x27;&#x27;;
}
</code></pre><p>After you load your custom configuration, you may use an <code class="literal">init.lua</code> located in
your custom configuration directory to configure Neovim exactly as you would
without a wrapper like nvf. If you want to place your <code class="literal">require</code> call in a
specific position (i.e., before or after options you set in nvf) the
<a class="link" href="https://notashelf.github.io/nvf/index.xhtml#ch-using-dags" target="_top">DAG system</a> will let you place your configuration in a location of your
choosing.</p>

as possible without leaving any question marks in your head.</p><p>This section is directed mainly towards those who wish to contribute code into
the project. If you instead wish to report a bug, or discuss a potential new
feature implementation (which you do not wish to implement yourself) first look
among the already <a class="link" href="https://github.com/notashelf/nvf/issues" target="_top">open issues</a> and if no matching issue exists you may open a

someOtherValue = mkOption {
type = lib.types.bool;
default = true;

faster option that should be preferred if the plugin consists of pure Lua or
Vimscript code. In which case there is no building required, and we can easily
handle the copying of plugin files. Alternative method, which is required when
plugins try to build their own libraries (e.g., in Rust or C) that need to be
built with Nix to function correctly.</p><div class="section"> <div class="titlepage"> <div> <div> <h2 id="sec-npins-for-plugins" class="title" style="clear: both">With npins </h2> </div> </div></div><p>npins is the standard method of adding new plugins to <span class="strong"><strong>nvf</strong></span>. You simply need
the repository URL for the plugin, and can add it as a source to be built
automatically with one command. To add a new Neovim plugin, use <code class="literal">npins</code>. For
example:</p><pre><code class="programlisting bash">nix-shell -p npins # or nix shell nixpkgs#npins if using flakes
</code></pre><p>Then run:</p><pre><code class="programlisting bash">npins add --name &lt;plugin name&gt; github &lt;owner&gt; &lt;repo&gt; -b &lt;branch&gt;

correctly. For example <a class="link" href="https://github.com/Saghen/blink.cmp" target="_top">blink.cmp</a> requires its own fuzzy matcher library, built
with Rust, to be installed or else defaults to a much slower Lua implementation.
In the Blink documentation, you are advised to build with <code class="literal">cargo</code> but that is
not ideal since we are leveraging the power of Nix. In this case the ideal
solution is to write a derivation for the plugin.</p><p>We use <code class="literal">buildRustPackage</code> to build the library from the repository root, and
copy everything in the <code class="literal">postInstall</code> phase.</p><pre><code class="programlisting nix">postInstall = &#x27;&#x27;

mkdir -p &quot;$out/target&quot;
mv &quot;$out/lib&quot; &quot;$out/target/release&quot;
&#x27;&#x27;;
</code></pre><p>In a similar fashion, you may utilize <code class="literal">stdenv.mkDerivation</code> and other Nixpkgs
builders to build your library from source, and copy the relevant files and Lua
plugin files in the <code class="literal">postInstall</code> phase. Do note, however, that you still need
to fetch the plugin sources somehow. npins is, once again, the recommended
option to fetch the plugin sources. Refer to the previous section on how to use
npins to add a new plugin.</p><p>Plugins built from source must go into the <code class="literal">flake/pkgs/by-name</code> overlay. It will
automatically create flake outputs for individual packages. Lastly, you must add
your package to the plugin builder (<code class="literal">pluginBuilders</code>) function manually in
<code class="literal">modules/wrapper/build/config.nix</code>. Once done, you may refer to your plugin as a
