</ul>
It supports all Prism features, namely:
<ul>
<li>Syntax highlighting (30+ languages)</li>
<li>Custom themes (6 official themes)</li>
<li>Plugins (7 official plugins: <a href="http://prismjs.com/plugins/line-highlight" rel="nofollow ugc">Line Highlight</a>, <a href="http://prismjs.com/plugins/line-numbers" rel="nofollow ugc">Line Numbers</a>, <a href="http://prismjs.com/plugins/show-invisibles" rel="nofollow ugc">Show Invisibles</a>, <a href="http://prismjs.com/plugins/autolinker" rel="nofollow ugc">Autolinker</a>, <a href="http://prismjs.com/plugins/wpd" rel="nofollow ugc">WebPlatform Docs</a>, <a href="http://prismjs.com/plugins/file-highlight" rel="nofollow ugc">File Highlight</a>, <a href="http://prismjs.com/plugins/show-language" rel="nofollow ugc">Show Language</a>)</li>

<li>your_plugin_directory/wp-prism-syntax-highlighter/css/</li>
<li>your_plugin_directory/wp-prism-syntax-highlighter/js/ 
Do NOT replace the original prism.css and prism.js, you will lose all your changes as they get overwritten when updating the plugin!</li>

Why another Prism plugin? 
If you searched the plugin directory, you certainly noticed that there are several Prism plugins for WordPress. Well, none of them satisfied me: one plugin had no code editor, the other didn’t escape HTML tags, another didn’t have the options I needed… so I made a new one to suit my needs.

WP Prism Syntax Highlighter

A lightweight and convenient plugin to integrate Prism Syntax Highlighter into WordPress.

Dan D

Codeblocks Extended with PrismJS was born of a personal need for a lightweight code highlighter, with special functionality. 
Many of the other PrismJS based plugins in the repository were either outdated, or were lacking features that I was looking for.
Features:
<ul>
<li>Integrates the latest PrismJS build, with the most common langauges used.</li>
<li>Integrates the PrismJS line-numbers plugin, to automatically number lines of code.</li>
<li>Integrates the PrismJS line-highlight plugin to allow you to highlight specific lines of code.</li>
<li>Integrates ClipboardJS + custom jQuery to add a “Copy to Clipboard” button to each code block.</li>
<li>Custom Text Editor button to wrap selected text with the most commmon <code><pre></code> and <code><code></code> classes, and replacing special characters with their HTML safe equivalents.</li>
<li>Custom Visual Editor / TinyMCE dropdown button, with the most common languages to wrap selected text.</li>
<li>Since this works via wrapping <code><pre></code> and <code><code></code> tags with classes, you can use all custom class settings that PrismJS offers.</li>
<li>No shortcodes to mess with, so you don’t have to worry about losing whitespace between editor modes.</li>
<li>No settings page needed: Just activate it and go!</li>
</ul>
For a full list of languages supported and more information on this plugin’s use, please check out the FAQ.
Note: This does NOT auto-detect the language. Most plugins that do so brute force the languages or require file extensions, resulting in a much heavier plugin. The decision was made to keep this as light-weight as possible.
Note 2: This is designed to work with the Classic Editor. It does not currently work in Gutenberg blocks.
