<div class="navigation"><a href="/glyph/book/extending/task.html">Defining Custom Tasks ←</a><a href="/glyph/book/index.html">Contents</a><a href="/glyph/book/extending/command.html">→ Defining Custom Commands</a></div>
<p>As shown in <a href="/glyph/book/extending/commands_tasks.html#cmd_tasks_arch">How Commands and Tasks work</a>, the <a href="/glyph/book/ref_commands.html#c_compile"><code>compile</code></a> command command calls specific tasks defined in the <code>generate:</code> Rake namespace to generate output files in a particular format.</p>
<p>More specifically, when a <code>--format</code> option is specified, the command looks for a task with the same name within the <code>generate:</code> namespace. This makes adding new output formats to Glyph a fairly easy task, without the need to specify custom commands or similar.</p>
<p>The following sections explain how the <code>h3rald</code> output format was created to integrate this book into the <a href="http://www.h3rald.com">H3RALD.com</a> website.</p>
<div class="section">
<h6 id="h_93">Output Configuration</h6>
<p>The first step required to add a new output format to Glyph is extending Glyph’s configuration by adding the appropriate output hash, as follows:</p>
<pre class="lazy"><span class="line-numbers"> 1 </span> :<span class="MetaTag"><span class="MetaTag">output</span><span class="MetaTag">:</span> </span>
<span class="line-numbers"> 2 </span> :<span class="MetaTag"><span class="MetaTag">h3rald</span><span class="MetaTag">:</span> </span>
<span class="line-numbers"> 3 </span> :<span class="String"><span class="Entity">multifile<span class="Entity">:</span></span> <span class="String">true</span></span>
<span class="line-numbers"> 4 </span> :<span class="MetaTag"><span class="MetaTag">extension</span><span class="MetaTag">:</span> </span><span class="String"><span class="String">'</span>.html<span class="String">'</span></span>
<span class="line-numbers"> 5 </span> :<span class="MetaTag"><span class="MetaTag">filter_target</span><span class="MetaTag">:</span> </span><span class="String"><span class="String">'</span>html<span class="String">'</span></span>
<span class="line-numbers"> 6 </span> :<span class="MetaTag"><span class="MetaTag">base</span><span class="MetaTag">:</span> </span><span class="String"><span class="String">'</span>/glyph/book/<span class="String">'</span></span>
<span class="line-numbers"> 7 </span> :<span class="MetaTag"><span class="MetaTag">macro_dirs</span><span class="MetaTag">:</span> </span>[<span class="String"><span class="String">'</span>html<span class="String">'</span></span>]
<span class="line-numbers"> 8 </span> :<span class="MetaTag"><span class="MetaTag">layout_dirs</span><span class="MetaTag">:</span> </span>[<span class="String"><span class="String">'</span>web<span class="String">'</span></span>]
<span class="line-numbers"> 9 </span> :<span class="MetaTag"><span class="MetaTag">layouts</span><span class="MetaTag">:</span> </span>
<span class="line-numbers"> 10 </span> :<span class="String"><span class="Entity">topic<span class="Entity">:</span></span> <span class="String">bookpage</span></span>
<span class="line-numbers"> 11 </span> :<span class="String"><span class="Entity">index<span class="Entity">:</span></span> <span class="String">bookindex</span></span>
</pre>
<p>In particular, the following keys are mandatory:</p>
<ul>
<li>multifile</li>
<li>extension</li>
<li>filter_target</li>
<li>base</li>
<li>macro_dirs</li>
<li>layout_dirs</li>
</ul>
</div>
<div class="section">
<h6 id="h_94">Creating a 'generate:h3rald' task</h6>
<p>The next (and final) step involves creating a custom <code>h3rald</code> task within the <code>generate:</code> namespace. This task can be placed in any <code>.rake</code> file within the <code>lib/tasks</code> directory:</p>
<pre class="lazy"><span class="line-numbers"> 1 </span> namespace <span class="Constant"><span class="Constant">:</span>generate</span> <span class="Keyword">do</span>
<span class="line-numbers"> 2 </span> desc <span class="String"><span class="String">"</span>Create output for h3rald.com integration<span class="String">"</span></span>

<p>In this case, this task does not actually renders files in a different format, it just moves the files generated by the @generate:web@ task in different subdirectories.</p>
<p>Additionally, it also generates the <a href="http://www.h3rald.com/glyph/">Glyph project page</a> from the book's introduction (note the usage of a raw custom layout macro).</p>
