  385. <p>Like most other classes in CodeIgniter, the Typography class is
  386. initialized in your controller using the <code class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></code> method:</p>
  387. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;typography&#39;</span><span class="p">);</span>
  388. </pre></div>
  389. </div>
  390. <p>Once loaded, the Typography library object will be available using:</p>
  391. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">typography</span>

  404. <dd><p>When using the Typography library in conjunction with the <a class="reference internal" href="parser.html"><span class="doc">Template Parser library</span></a>
  405. it can often be desirable to protect single and double quotes within curly braces.
  406. To enable this, set the <code class="docutils literal"><span class="pre">protect_braced_quotes</span></code> class property to TRUE.</p>
  407. <p>Usage example:</p>
  408. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;typography&#39;</span><span class="p">);</span>

  434. <p>Formats text so that it is semantically and typographically correct HTML.
  435. Takes a string as input and returns it with the following formatting:</p>
  436. <blockquote>
  437. <div><ul class="simple">
  438. <li>Surrounds paragraphs within &lt;p&gt;&lt;/p&gt; (looks for double line breaks to identify paragraphs).</li>
  439. <li>Single line breaks are converted to &lt;br /&gt;, except those that appear within &lt;pre&gt; tags.</li>
  440. <li>Block level elements, like &lt;div&gt; tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>
  441. <li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
  442. <li>Apostrophes are converted to curly apostrophe entities.</li>
  443. <li>Double dashes (either like – this or like–this) are converted to em—dashes.</li>
  444. <li>Three consecutive periods either preceding or following a word are converted to ellipsis (…).</li>
  445. <li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
  446. </ul>
  447. </div></blockquote>
  448. <p>Usage example:</p>
  449. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">typography</span><span class="o">-&gt;</span><span class="na">auto_typography</span><span class="p">(</span><span class="nv">$string</span><span class="p">);</span>
  450. </pre></div>
  451. </div>
  452. <p>There is one optional parameter that determines whether the parser should reduce more than two consecutive line breaks down to two.
  453. Pass boolean TRUE to enable reducing line breaks:</p>
  454. <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">typography</span><span class="o">-&gt;</span><span class="na">auto_typography</span><span class="p">(</span><span class="nv">$string</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
