| <h1>Typography Class</h1> |
| |
| <p>The Typography Class provides functions that help you format text.</p> |
| |
| |
| <h2>Initializing the Class</h2> |
| |
| <p>Like most other classes in CodeIgniter, the Typography class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p> |
| |
| <code>$this->load->library('typography');</code> |
| <p>Once loaded, the Typography library object will be available using: <dfn>$this->typography</dfn></p> |
| |
| |
| <h2>auto_typography()</h2> |
| |
| <p>Formats text so that it is semantically and typographically correct HTML. Takes a string as input and returns it with |
| the following formatting:</p> |
| |
| <ul> |
| <li>Surrounds paragraphs within <p></p> (looks for double line breaks to identify paragraphs).</li> |
| <li>Single line breaks are converted to <br />, except those that appear within <pre> tags.</li> |
| <li>Block level elements, like <div> tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li> |
| <li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li> |
| <li>Apostrophes are converted to curly apostrophe entities.</li> |
| <li>Double dashes (either like -- this or like--this) are converted to em—dashes.</li> |
| <li>Three consecutive periods either preceding or following a word are converted to ellipsis…</li> |
| <li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li> |
| </ul> |
| |
| <p>Usage example:</p> |
| |
| <code>$string = $this->typography->auto_typography($string);</code> |
| |
| <h3>Parameters</h3> |
| |
| <p>There is one optional parameters that determines whether the parser should reduce more then two consecutive line breaks down to two. Use boolean <kbd>TRUE</kbd> or <kbd>FALSE</kbd>. |
| |
| <p>By default the parser does not reduce line breaks. In other words, if no parameters are submitted, it is the same as doing this:</p> |
| |
| <code>$string = $this->typography->auto_typography($string, <kbd>FALSE</kbd>);</code> |
| |
| |
| <p class="important"><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>format_characters()</h2> |
| |
| <p>This function is similar to the <dfn>auto_typography</dfn> function above, except that it only does character conversion:</p> |
| |
| <ul> |
| <li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li> |
| <li>Apostrophes are converted to curly apostrophe entities.</li> |
| <li>Double dashes (either like -- this or like--this) are converted to em—dashes.</li> |
| <li>Three consecutive periods either preceding or following a word are converted to ellipsis…</li> |
| <li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li> |
| </ul> |
| |
| <p>Usage example:</p> |
| |
| <code>$string = $this->typography->format_characters($string);</code> |
| |
| |
| <h2>nl2br_except_pre()</h2> |
| |
| <p>Converts newlines to <br /> tags unless they appear within <pre> tags. |
| This function is identical to the native PHP <dfn>nl2br()</dfn> function, except that it ignores <pre> tags.</p> |
| |
| <p>Usage example:</p> |
| |
| <code>$string = $this->typography->nl2br_except_pre($string);</code> |
| |
| <h2>protect_braced_quotes</h2> |
| |
| <p>When using the Typography library in conjunction with the Template Parser library it can often be desirable to protect single |
| and double quotes within curly braces. To enable this, set the <kbd>protect_braced_quotes</kbd> class property to <samp>TRUE</samp>. |
| |
| <p>Usage example:</p> |
| |
| <code>$this->load->library('typography');<br /> |
| $this->typography->protect_braced_quotes = TRUE; |
| </code> |
