<p>Out of the box, <a href="https://wordpress.org/extend/plugins/wp-syntax/" rel="ugc">WP-Syntax</a><br />
colors code using the default <a href="http://qbnz.com/highlighter/" rel="nofollow ugc">GeSHi</a> colors.<br />
Per the authors advice in the ‘Advanced Customization’ section of<br />
<a href="https://wordpress.org/extend/plugins/wp-syntax/other_notes/" rel="ugc">Other Notes</a>,<br />
you can configure GeSHi yourself by handling the <code>wp_syntax_init_geshi</code><br />
hook and configuring it programmatically.</p>
<p>Since I wanted to do just that, I decided to publish a generic plugin<br />
for folks who wanted to configure GeSHi following this approach.</p>
<h3>Release Notes</h3>
<p><strong>1.2</strong> : Set keyword expansion in the plugin file. Uses Wp-Syntax 0.9, which depends on GeSHi 1.0.7.22.</p>
<p><strong>1.1</strong> : Fixed grammatical errors in the readme.txt. Uses Wp-Syntax 0.9, which depends on GeSHi 1.0.7.22.</p>
<p><strong>1.0</strong> : First public release. Uses Wp-Syntax 0.9, which depends on GeSHi 1.0.7.22.</p>

<p>Integrates the <a href="https://github.com/LeaVerou/prism" rel="nofollow ugc">Prism Syntax Highlighting Library</a> in WordPress.</p>
<p>It is called <em>detached</em>, since the code examples are not stuffed into the rich text editor, together with all the<br />
other texts and content, but they are added separately as custom fields and just referenced via short tags (like footnotes).</p>
<p>Check <em>Other Notes</em> for usage documentation.</p>
<p>The official development repository is <a href="https://github.com/apfelbox/Prism-Detached" rel="nofollow ugc">hosted on Github</a>.</p>
<h3>Usage</h3>
<p>The basic procedure is:</p>
<ol>
<li>Create a custom field and paste the code into it.</li>
<li>Insert the <code>[prism ...]</code> shorttag in your code, where you want the code block to appear.</li>
</ol>
<h4>Shorttag</h4>
<pre><code>[prism key=".." language=".." line=".." line_offset=".." post=".."]
</code></pre>
<ul>
<li><code>key</code>: the name of the custom field, which contains the code (<strong>required</strong>)</li>
<li><code>language</code>: the language to highlight</li>
<li><code>line</code>: highlighted lines (for syntax, check the <a href="http://prismjs.com/plugins/line-highlight/" rel="nofollow ugc">offical docs</a>)</li>
<li><code>line_offset</code>: the offset, with which the line numbering should start</li>
<li><code>post</code>:  if you want to include a code piece of another post, you can explicitly specify the post id here</li>
</ul>
<h4>Cached Assets loader</h4>
<p>The plugin includes (from v1.3 on) a cached assets loader, so that all needed assets are concatenated into<br />
one js and one css file to minimize the HTTP requests.<br />
To make use of the cached assets loader, just create a directory <code>/cache/</code> inside your plugin directory and make it writable for PHP.</p>
<h4>Supported languages</h4>
<p>Only the ones from the official PrismJS repository</p>
<ul>
<li>bash (Bash Unix Shell)</li>
<li>c</li>
<li>clike</li>
<li>coffeescript</li>
<li>cpp (C++)</li>
<li>css</li>
<li>groovy</li>
<li>java</li>
<li>javascript</li>
<li>markup (like: xHTML, MathML, SVG, LaTeX, RSS, XML, OWL, etc.)</li>
<li>php</li>
<li>python</li>
<li>scss (Sassy CSS)</li>
<li>sql</li>
</ul>
