<h1 class="page-title">Menu Modules</h1>
<h2 id="menu-modules">Menu Modules</h2>
<p>From initial connection to the screens and mods your users interact with, the entire experience is made up of menu entries — And all menu entries found within <a href="/enigma-bbs/configuration/menu-hjson.html">menu.hjson</a> are backed by <em>Menu Modules</em>. For basic menus, a standard handler is implemented requiring no code. However, if you would like to create a menu that has custom handling, you will very likely be inheriting from from <code class="language-plaintext highlighter-rouge">MenuModule</code>. More on this below.</p>
<blockquote>
<p><img class="emoji" title=":information_source:" alt=":information_source:" src="https://github.githubassets.com/images/icons/emoji/unicode/2139.png" height="20" width="20"> Remember that ENiGMA does not impose any stucture to your system! The “flow” of all <code class="language-plaintext highlighter-rouge">menu.hjson</code> entries is up to you!</p>
</blockquote>
<blockquote>
<p><img class="emoji" title=":bulb:" alt=":bulb:" src="https://github.githubassets.com/images/icons/emoji/unicode/1f4a1.png" height="20" width="20"> If the <code class="language-plaintext highlighter-rouge">module</code> entry is not present in a <code class="language-plaintext highlighter-rouge">menu.hjson</code> entry, the system automatically uses <a href="/core/standard_menu.js">standard_menu.js</a>.</p>
</blockquote>
<h2 id="creating-a-new-module">Creating a New Module</h2>
<p>At the highest level, to create a new custom menu or mod, inherit from <code class="language-plaintext highlighter-rouge">MenuModule</code> and expose it via the <code class="language-plaintext highlighter-rouge">getModule</code> exported method:</p>
<div class="language-javascript highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c1">// my_fancy_module.js</span>
<span class="nx">exports</span><span class="p">.</span><span class="nx">getModule</span> <span class="o">=</span> <span class="kd">class</span> <span class="nx">MyFancyModule</span> <span class="kd">extends</span> <span class="nx">MenuModule</span> <span class="p">{</span>

<span class="p">}</span>
<span class="p">};</span>
</code></pre></div></div>
<p>Next, override the appropriate methods to add some functionality! Below is an example fragment overriding just <code class="language-plaintext highlighter-rouge">initSequence()</code>:</p>
<div class="language-javascript highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nx">initSequence</span><span class="p">()</span> <span class="p">{</span>

<span class="p">};</span>
</code></pre></div></div>
<h3 id="per-mod-databases">Per-Mod Databases</h3>
<p>Custom mods often need their own data persistence. This can be acheived with <code class="language-plaintext highlighter-rouge">getModDatabsePath()</code> and your <code class="language-plaintext highlighter-rouge">ModuleInfo</code>s <code class="language-plaintext highlighter-rouge">packageName</code>.</p>
<p><strong>Example</strong>:</p>
<div class="language-javascript highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nb">self</span><span class="p">.</span><span class="nx">database</span> <span class="o">=</span> <span class="nx">getTransactionDatabase</span><span class="p">(</span>

<span class="p">);</span>
</code></pre></div></div>
<p>Given the <code class="language-plaintext highlighter-rouge">packageName</code> above, a database will be created at the following location:</p>
<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nv">$enigma</span><span class="nt">-bbs</span>/db/mods/com.myname.foo.super-dope-mod.sqlite3
</code></pre></div></div>
<h3 id="menu-methods">Menu Methods</h3>
<p>Form handler methods specified by <code class="language-plaintext highlighter-rouge">@method:someName</code> in your <code class="language-plaintext highlighter-rouge">menu.hjson</code> entries map to those found in your modules <code class="language-plaintext highlighter-rouge">menuMethods</code> object. That is, <code class="language-plaintext highlighter-rouge">this.menuMethods</code> and have the following signature <code class="language-plaintext highlighter-rouge">(formData, extraArgs, cb)</code>. For example, consider the following <code class="language-plaintext highlighter-rouge">menu.hjson</code> fragment:</p>
<pre><code class="language-hjson">actionKeys: [
{
keys: [ "a", "shift + a" ]
action: @method:toggleAvailable

]
</code></pre>
<p>We can handle this in our module as such:</p>
