<p><strong>LumiCode</strong> 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/</p>
<h3>Key Features</h3>
<ul>
<li><strong>40+ languages</strong> auto-detected – PHP, JavaScript, TypeScript, Python, Go, Rust, SQL, YAML, Bash, and more</li>
<li><strong>13 bundled themes</strong> – Atom One, Dracula, GitHub, Monokai, Night Owl, Nord, Solarized, VS 2015, Xcode, and more, powered by highlight.js 11.11.1</li>
<li><strong>Dark & Light mode</strong> – toggle from the admin topbar. Applies to both admin UI and frontend code boxes</li>
<li><strong>Copy to Clipboard</strong> – one-click copy button on every code block</li>
<li><strong>Line numbers</strong> – perfectly aligned, synced to font size and line height</li>
<li><strong>Collapse / Expand</strong> – long code blocks auto-collapse after a configurable number of lines</li>
<li><strong>Filename / language badge</strong> – shows in the titlebar of every code box</li>
<li><strong>TinyMCE integration</strong> – Insert Code Block button in the Classic Editor toolbar, with language detection and all options</li>
<li><strong>Gutenberg block</strong> – native block editor support</li>
<li><strong>Code Scanner</strong> – scans your entire site for bare <code><pre></code> blocks and lets you apply LumiCode with one click, or dismiss</li>
<li><strong>Auto-detect</strong> – wraps any existing <code><pre></code> blocks automatically on the frontend without touching your content</li>
</ul>
<h3>How It Works</h3>
<p>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.</p>
<p>No page builders required. Works with any theme.</p>
<h3>Shortcode Usage</h3>
<pre><code>[lumicode lang="javascript"]
const greeting = "Hello, world!";
console.log(greeting);
[/lumicode]
</code></pre>
<p><strong>All shortcode attributes:</strong><br />
* <code>lang</code> – language identifier (e.g. <code>php</code>, <code>python</code>, <code>typescript</code>)<br />
* <code>title</code> – filename shown in titlebar (e.g. <code>config.js</code>)<br />
* <code>highlight</code> – lines to accent (e.g. <code>1,3-5</code>)<br />
* <code>collapse</code> – force collapse (<code>true</code>/<code>false</code>)<br />
* <code>collapse-after</code> – collapse after N lines (overrides global setting)</p>
<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>
