<h1 class="title">advanced-code.org</h1>
<p>Turns out there&#8217;s more way to do code than just BEGIN_EXAMPLE.</p>
<h1><span class="heading-number heading-number-1">1</span> Inline examples</h1>
<p>This should work:</p>
<pre class="example">
  fixed width? how does this work?   
                        ...........
                       ............
                                  .
                       .  .   .   .
                       .          ..
                       ....... .....
                           .  .
                           ....
</pre>
<p>Two ASCII blobs.</p>
<h1><span class="heading-number heading-number-1">2</span> BEGIN_SRC</h1>
<p>And this:</p>
<div class="highlight"><pre><span class="c1"># Finds all emphasis matches in a string.</span>
<span class="c1"># Supply a block that will get the marker and body as parameters.</span>
<span class="k">def</span> <span class="nf">match_all</span><span class="p">(</span><span class="n">str</span><span class="p">)</span>
