Despite two plugins already on wordpress.org I decided to write my own from scratch. The result is a minimalistic but powerful plugin with only ~250 lines of PHP.
<ul>
<li>Supports every possible Prism configuration.</li>
<li>Adds TinyMCE dropdown lost for <code><code class="language-xxx"> and <pre class="language-xxx"></code> for bash, css, js, markup, php, scss. (I can make a filter if you want to add more.)</li>
<li>Does not load prism on every page, only when needed.</li>
<li>Supports automatic detection of prism HTML.</li>
<li>Supports displaying code from custom fields with <code>[prism]</code> shortcode.</li>
<li>Developers may use the <code>prism</code> handle to enqueue the pre-registered script and style.</li>
<li>Has admin editor button for quick shortcode template snippet.</li>
<li>Has no options page by design.</li>

Easily highlight your code on WordPress with WP PrismJS.
Simply download & activate the plugin and a new icon on your TinyMCE editor will appear. Click on it and you will be able to enter your indented code; choose the language; specifying the maximum height of the code window and the filename.
