<p>Notes on <code class="language-plaintext highlighter-rouge">publicHostname</code> and <code class="language-plaintext highlighter-rouge">publicPort</code>:
The Gopher protocol serves content that contains host/domain and port even when referencing it’s own documents. Due to this, these members must be set to your publicly addressable Gopher server!</p>
<h2 id="gophermaps">Gophermap’s</h2>
<p><a href="https://en.wikipedia.org/wiki/Gopher_(protocol)#Source_code_of_a_menu">Gophermap’s</a> are how to build menus for your Gopher Hole. Each map is a simple text file named <code class="language-plaintext highlighter-rouge">gophermap</code> (all lowercase, no extension) with DOS style CRLF endings.</p>
<p>Within any directory nested within your <code class="language-plaintext highlighter-rouge">staticRoot</code> may live a <code class="language-plaintext highlighter-rouge">gophermap</code>. A template may be found in the <code class="language-plaintext highlighter-rouge">enigma-bbsmisc</code> directory.</p>
<p>ENiGMA will pre-process <code class="language-plaintext highlighter-rouge">gophermap</code> files replacing in following variables:</p>
<ul>
<li>
<code class="language-plaintext highlighter-rouge">{publicHostname}</code>: The public hostname from your config.</li>
<li>
<code class="language-plaintext highlighter-rouge">{publicPort}</code>: The public port from your config.</li>

<h3 id="example-gophermap">Example Gophermap</h3>
<p>An example <code class="language-plaintext highlighter-rouge">gophermap</code> living in <code class="language-plaintext highlighter-rouge">enigma-bbs/gopher</code>:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>iWelcome to a Gopher server! {publicHostname} {publicPort}
1Public Message Area /msgarea {publicHostname} {publicPort}
.
</code></pre></div></div>
<h3 id="example">Example</h3>
<p>Let’s suppose you are serving Gopher for your BBS at <code class="language-plaintext highlighter-rouge">myfancybbs.com</code>. Your ENiGMA½ system is listening on the default Gopher <code class="language-plaintext highlighter-rouge">port</code> of 8070 but you’re behind a firewall and want port 70 exposed to the public. Lastly, you want to expose some fsxNet areas:</p>
<pre><code class="language-hjson">contentServers: {
gopher: {
enabled: true
publicHostname: myfancybbs.com
publicPort: 70
// Expose some public message conferences/areas
messageConferences: {
fsxnet: { // fsxNet's conf tag
// Areas of fsxNet we want to expose:
"fsx_gen", "fsx_bbs"
}
}
}
}
</code></pre>
