<h1>Typography Helper</h1>

<p>The Typography Helper file contains functions that help your format text in semantically relevant ways.</p>


<h2>Loading this Helper</h2>

<p>This helper is loaded using the following code:</p>
<code>$this->load->helper('typography');</code>

<p>The following functions are available:</p>


<h2>auto_typography()</h2>

<p>Formats text so that it is semantically and typographically correct HTML.  Takes a string as input and returns it with
the following formatting:</p>

<ul>
<li>Surrounds paragraphs within &lt;p&gt;&lt;/p&gt; (looks for double line breaks to identify paragraphs).</li>
<li>Single line breaks are converted to &lt;br /&gt;, except those that appear within &lt;pre&gt; tags.</li>
<li>Block level elements, like &lt;div&gt; tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>
<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
<li>Apostrophes are converted to curly apostrophy entities.</li>
<li>Double dashes (either like -- this or like--this) are converted to em&#8212;dashes.</li>
<li>Three consecutive periods either preceding or following a word are converted to ellipsis&#8230;</li>
<li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
</ul>

<p>Usage example:</p>

<code>$string = auto_typography($string);</code>

<p><strong>Note:</strong> Typographic formatting can be processor intensive, particularly if you have a lot of content being formatted.
If you choose to use this function you may want to consider
<a href="../general/caching.html">caching</a> your pages.</p>


<h2>nl2br_except_pre()</h2>

<p>Converts newlines to &lt;br /&gt; tags unless they appear within &lt;pre&gt; tags.
This function is identical to the native PHP <dfn>nl2br()</dfn> function, except that it ignores &lt;pre&gt; tags.</p>

<p>Usage example:</p>

<code>$string = nl2br_except_pre($string);</code>
