<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

manner.</p><pre><code class="programlisting nix">{

outdated (or, more likely, broken) it is possible to build the plugins from
source using a tool, such as <a class="link" href="https://github.com/andir/npins" target="_top">npins</a>. You may also use your <span class="emphasis"><em>flake inputs</em></span> as
sources.</p><p>Example using plugin inputs:</p><pre><code class="programlisting nix">{

};
};
# Make sure that &#x27;inputs&#x27; is properly propagated into Nvf, for example, through
# specialArgs.
outputs = { ... };
}
</code></pre><p>In the case, you may use the input directly for the plugin’s source attribute in
<code class="literal">buildVimPlugin</code>.</p><pre><code class="programlisting nix"># Make sure that &#x27;inputs&#x27; is properly propagated! It will be missing otherwise

setup = &quot;require(&#x27;aerial&#x27;).setup {}&quot;;
};
};
}
</code></pre><p>Alternatively, if you do not want to keep track of the source using flake inputs

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 nvf’s 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.

you are new to Git and GitHub, do have a look at GitHub’s
<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 we’ll gently nudge you in the correct
direction if there are any mistakes.</p>

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

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
# Note: try to be careful about the ordering of `mkOption` arguments.
# General rule of thumb is to order from least to most likely to change.
# This is, for most cases, type &lt; default &lt; description.
# Example, if present, would be between default and description
someOtherValue = mkOption {
type = lib.types.bool;
default = true;
description = &quot;Some other description&quot;;
};
};
}
</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];
