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>

Prism Syntax Highlighter for WordPress

Not working

Most lightweight, yet most configurable and advanced PrismJS WordPress integration plugin. Custom fields display (detached) supported.

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Many of the other PrismJS based plugins in the repository were either outdated, or were lacking features that I was looking for.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.
