be enough. In that case, you can write custom lua config using either
<code class="literal">config.vim.lazy.plugins.*.setupOpts</code> <code class="literal">config.vim.extraPlugins.*.setup</code> or
<code class="literal">config.vim.luaConfigRC</code>.</p><p>The first option uses an extended version of <code class="literal">lz.n</code>s PluginSpec. <code class="literal">setupModule</code>
and <code class="literal">setupOpt</code> can be used if the plugin uses a <code class="literal">require(&#x27;module&#x27;).setup(...)</code>
pattern. Otherwise, the <code class="literal">before</code> and <code class="literal">after</code> hooks should do what you need.</p><pre><code class="programlisting nix">{
config.vim.lazy.plugins = {
aerial.nvim = {
# ^^^^^^^^^ this name should match the package.pname or package.name
package = aerial-nvim;
setupModule = &quot;aerial&quot;;
setupOpts = {option_name = false;};
after = &quot;print(&#x27;aerial loaded&#x27;)&quot;;
};
};
}
</code></pre><p>The second option uses an attribute set, which maps DAG section names to a
custom type, which has the fields <code class="literal">package</code>, <code class="literal">after</code>, <code class="literal">setup</code>. They allow you to
set the package of the plugin, the sections its setup code should be after (note
that the <code class="literal">extraPlugins</code> option has its own DAG scope), and the its setup code
respectively. For example:</p><pre><code class="programlisting nix">config.vim.extraPlugins = with pkgs.vimPlugins; {
aerial = {
package = aerial-nvim;
setup = &quot;require(&#x27;aerial&#x27;).setup {}&quot;;
};
harpoon = {
package = harpoon;
setup = &quot;require(&#x27;harpoon&#x27;).setup {}&quot;;
after = [&quot;aerial&quot;]; # place harpoon configuration after aerial
};
}
</code></pre><p>The third option also uses an attribute set, but this one is resolved as a DAG
directly. The attribute names denote the section names, and the values lua code.
For example:</p><pre><code class="programlisting nix">{
# this will create an &quot;aquarium&quot; section in your init.lua with the contents of your custom config
# which will be *appended* to the rest of your configuration, inside your init.vim

We
would like for any contributor to be able to propagate their changes, or add new
features to the project with minimum possible friction. As such, below are the
guides and guidelines written to streamline the contribution process and to
ensure that your valuable input integrates into nvfs development as seamlessly
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
<a class="link" href="https://github.com/notashelf/nvf/issues/new" target="_top">new issue</a> and describe your problem/request.</p><p>While creating an issue, please try to include as much information as you can,
ideally also include relevant context in which an issue occurs or a feature
should be implemented. If you wish to make a contribution, but feel stuck -
please do not be afraid to submit a pull request, we will help you get it in.</p><div class="section"> <div class="titlepage"> <div> <div> <h1 id="sec-contrib-getting-started" class="title" style="clear: both">Getting Started </h1> </div> </div></div><p>You, naturally, would like to start by forking the repository to get started. If
you are new to Git and GitHub, do have a look at GitHubs
<a class="link" href="https://help.github.com/articles/fork-a-repo/" target="_top">Fork a repo guide</a> for
instructions on how you can do this. Once you have a fork of <span class="strong"><strong>nvf</strong></span>, you should
create a separate branch based on the most recent <code class="literal">main</code> branch. Give your
branch a reasonably descriptive name (e.g. <code class="literal">feature/debugger</code> or
<code class="literal">fix/pesky-bug</code>) and you are ready to work on your changes</p><p>Implement your changes and commit them to the newly created branch and when you
are happy with the result, and positive that it fulfills our
<a class="link" href="index.xhtml#sec-guidelines" title="Guidelines" >Contributing Guidelines</a>, push the branch to GitHub and
<a class="link" href="https://help.github.com/articles/creating-a-pull-request" target="_top">create a pull request</a>.
The default pull request template available on the <span class="strong"><strong>nvf</strong></span> repository will guide
you through the rest of the process, and well gently nudge you in the correct
direction if there are any mistakes.</p>

it will be merged without too much trouble. Some of the guidelines will be
strictly enforced, others will remain as gentle nudges towards the correct
direction. As we have no automated system enforcing those guidelines, please try
to double check your changes before making your pull request in order to avoid
“faulty” code slipping by.</p><p>If you are uncertain how these rules affect the change you would like to make

albeit with exceptions.</p><p>::: {.note} As of <span class="strong"><strong>v0.5</strong></span>, <span class="strong"><strong>nvf</strong></span> is itself documented using full markdown in

that is introduced in an earlier commit. In particular, you will be asked to
amend any commit that introduces syntax errors or similar problems even if they
are fixed in a later commit.</p><p>The commit messages should follow the
<a class="link" href="https://chris.beams.io/posts/git-commit/#seven-rule" target="_top">seven rules</a>, except for
“Capitalize the subject line”. We also ask you to include the affected code
component or module in the first line. A commit message ideally, but not
necessarily, follow the given template from home-managers own documentation</p><pre><code class="programlisting"> {component}: {description}
{long description}

affects, <code class="literal">{description}</code> is a very brief description of your change, and

if there is no clear component, or your change affects many components, then the

minor fix in spelling or a formatting change does not warrant long description,
however, a module addition or removal does as you would like to provide the
relevant context, i.e. the reasoning behind it, for your commit.</p><p>Finally, when adding a new module, say <code class="literal">modules/foo.nix</code>, we use the fixed
commit format <code class="literal">foo: add module</code>. You can, of course, still include a long
description if you wish.</p><p>In case of nested modules, i.e <code class="literal">modules/languages/java.nix</code> you are recommended

certain changes are done at the users discretion based on how the original code

example:</p><pre><code class="programlisting nix"># parent modules should always be unfolded

module = {
value = mkEnableOption &quot;some description&quot; // { default = true; }; # merges can be done inline where possible
# same as parent modules, unfold submodules
subModule = {
# this is an option that contains more than one nested value
someOtherValue = mkOption {
type = lib.types.bool;
description = &quot;Some other description&quot;;
default = true;
};
};
}
</code></pre><p>If you move a line down after the merge operator, Alejandra will automatically
unfold the whole merged attrset for you, which we <span class="strong"><strong>do not</strong></span> want.</p><pre><code class="programlisting nix">module = {
key = mkEnableOption &quot;some description&quot; // {
default = true; # we want this to be inline
}; # ...
}
</code></pre><p>For lists, it is mostly up to your own discretion how you want to format them,
but please try to unfold lists if they contain multiple items and especially if
they are to include comments.</p><pre><code class="programlisting nix"># this is ok
acceptableList = [
item1 # comment
item2
item3 # some other comment
item4
];
# this is not ok
listToBeAvoided = [item1 item2 /* comment */ item3 item4];
