For years I’ve used <a href="http://alexgorbatchev.com/SyntaxHighlighter/" rel="nofollow ugc">Alex Gorbatchev’s SyntaxHighlighter</a>. It has served me well over the years. When I moved to WordPress I tried various plugins based on the library, such <a href="https://wordpress.org/extend/plugins/syntaxhighlighter/" rel="ugc">SyntaxHighlighter Evolved</a>.
I’ve decided to start blogging using <a href="http://daringfireball.net/projects/markdown/" rel="nofollow ugc">Markdown</a>. Making this move I needed to find a way to highlight various bits of source code in an easy way. There are many nice libraries that make this a snap, such as <a href="http://code.google.com/p/google-code-prettify/" rel="nofollow ugc">google-code-prettify</a> or <a href="http://softwaremaniacs.org/soft/highlight/en/" rel="nofollow ugc">highlight.js</a>. In the end I decided to go with highlight.js, for the simple reason that it is automatic, working flawlessly with Markdown’s code syntax output.
Great, but my existing source code examples use SyntaxHighlighter’s style for code blocks (using <code><pre class="brush: ruby;" /></code>, for example). I could have converted things in a few ways:
<ul>
<li>Change the database</li>
<li>Write a JS script to convert the <code><pre /></code> structure to <code><pre><code /></pre></code></li>
<li>Write a JS script to call highlight.js’ <code>highlightBlock</code> method</li>
<li>Write a WP plugin and reformat things easily Ding Ding Ding</li>
</ul>
So there you have it. This WordPress plugin will go through and process your SyntaxHighlighter style blocks into ones that highlight.js works with out-of-the-box. It will also add the language that you have specified with the <code>brush</code> class and add it as a class on the <code><code /></code> element (<a href="http://www.w3.org/html/wg/drafts/html/master/text-level-semantics.html#the-code-element" rel="nofollow ugc">following the HTML5 recommendation</a>). Nothing is changed in the DB, so if you decide to go back to SyntaxHighlighter, you can without any issues.
<h3>GeSHi</h3>
This plugin now supports conversion of <a href="http://qbnz.com/highlighter/" rel="nofollow ugc">GeSHi</a> style code blocks! Now you can move from plugins such as <a href="https://wordpress.org/extend/plugins/wp-syntax/" rel="ugc">WP-Syntax</a> and <a href="https://wordpress.org/extend/plugins/wp-geshi-highlight" rel="ugc">WP-GeSHi-Highlight</a> to highlight.js.
GeSHi uses the syntax that is close to SyntaxHighlighter, except instead of putting the language in the <code>class</code> attribute, it uses the <code>lang</code> attribute. Similar to the SyntaxHighligher conversion, it will go through and process your GeSHi style blocks into ones that highlight.js works with out-of-the-box. It will also add the language that you have specified with the <code>lang</code> attribute and add it as a <code>class</code> on the <code><code /></code> element.

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>
