LumiCode is a premium-quality syntax highlighter built for developers and technical bloggers who want beautiful, readable code on their WordPress site – without fighting the editor. Learn more and view the live demo at https://cr8vstacks.com/dev-playground/lumicode-syntax-highlighter/
<h3>Key Features</h3>
<ul>
<li>40+ languages auto-detected – PHP, JavaScript, TypeScript, Python, Go, Rust, SQL, YAML, Bash, and more</li>
<li>13 bundled themes – Atom One, Dracula, GitHub, Monokai, Night Owl, Nord, Solarized, VS 2015, Xcode, and more, powered by highlight.js 11.11.1</li>
<li>Dark & Light mode – toggle from the admin topbar. Applies to both admin UI and frontend code boxes</li>
<li>Copy to Clipboard – one-click copy button on every code block</li>
<li>Line numbers – perfectly aligned, synced to font size and line height</li>
<li>Collapse / Expand – long code blocks auto-collapse after a configurable number of lines</li>
<li>Filename / language badge – shows in the titlebar of every code box</li>
<li>TinyMCE integration – Insert Code Block button in the Classic Editor toolbar, with language detection and all options</li>
<li>Gutenberg block – native block editor support</li>
<li>Code Scanner – scans your entire site for bare <code><pre></code> blocks and lets you apply LumiCode with one click, or dismiss</li>
<li>Auto-detect – wraps any existing <code><pre></code> blocks automatically on the frontend without touching your content</li>
</ul>
<h3>How It Works</h3>
LumiCode renders code blocks server-side (shortcodes + TinyMCE insertion) and enhances them on the frontend with a lightweight JS renderer. The renderer wraps <code><pre class="lumicode-pre"></code> elements in a beautiful VS Code-style chrome (titlebar, statusbar, line numbers, copy button) and runs highlight.js for syntax coloring.
No page builders required. Works with any theme.
<h3>Shortcode Usage</h3>
<pre><code>[lumicode lang="javascript"]
const greeting = "Hello, world!";
console.log(greeting);
[/lumicode]
</code></pre>
All shortcode attributes: 
* <code>lang</code> – language identifier (e.g. <code>php</code>, <code>python</code>, <code>typescript</code>) 
* <code>title</code> – filename shown in titlebar (e.g. <code>config.js</code>) 
* <code>highlight</code> – lines to accent (e.g. <code>1,3-5</code>) 
* <code>collapse</code> – force collapse (<code>true</code>/<code>false</code>) 
* <code>collapse-after</code> – collapse after N lines (overrides global setting)
<h3>Performance</h3>
<ul>
<li>highlight.js is loaded locally (v11.11.1) for speed and privacy</li>
<li>Our CSS and JS are tiny (<15 KB combined, unminified)</li>
<li>No jQuery dependency on the frontend</li>
</ul>

The CC-Syntax-Highlight plugin supports syntax highlighting of Posts, Pages, and any public Custom Post Types. 
It uses <a href="https://highlightjs.org/" rel="nofollow ugc">highlight.js</a> or <a href="https://github.com/google/code-prettify" rel="nofollow ugc">google-code-prettify</a> libraries. 
Additionally it can use the <a href="https://clipboardjs.com/" rel="nofollow ugc">clipboard.js</a> library to add a button that copies text to the clipboard and <a href="https://github.com/wcoder/highlightjs-line-numbers.js/" rel="nofollow ugc">highlightjs-line-numbers.js</a> plugin to add line numbers. 
It is delivered with support for shortcode (default [code] – you can change it on the settings page) which automatically converts all special characters to HTML entities. 
This plugin is compatible with Multisite WordPress installations.
<h4>How does it work?</h4>
<ol>
<li>Go to the ‘Settings > Syntax Highlight’ page, select your preferred options and save them.</li>
<li>Simply add the source code to your post (or other selected public Custom Post Type) wrapped with: 
<pre><code>Your source code</code></pre> 
or if you would like to automatically convert all special characters to HTML entities, use shortcode wrapper instead (default [code] – you can change it on the settings page): 
<pre>[code]Your source code[/code]</pre></li>
</ol>
Plugin’s js scripts and css styles files only load if the source code occurs on displaying page.

CC-Syntax-Highlight

This plugin allows you very simply syntax highlight source code in your content using highlight.js or google-code-prettify libraries.
