WP Markdown Syntax Sugar work in conjunction with plugins such as <a href="https://wordpress.org/extend/plugins/wp-markdown/" rel="ugc">wp-markdown</a> 
and <a href="https://wordpress.org/extend/plugins/wp-highlightjs/" rel="ugc">wp-highlight.js</a>. Markdown is fantastic markup for easily 
writing blogs, and <a href="http://softwaremaniacs.org/soft/highlight/en/" rel="nofollow ugc">highlight.js</a> is an extremely easy way to highlight 
code examples. In most cases, highlight.js automatically detects the proper language for a block of code. In certain 
cases, primarily if your code example is short, highlight.js could improperly detect the language that you are using; 
that is where this plugin comes into play. By adding one line to your code blocks, you can explicitly set the language 
that you are using, allowing highlight.js to properly format your code.
The concept is inspired by the <a href="https://github.com/spjwebster/wp-markdown-syntax-highlight" rel="nofollow ugc">wp-markdown-syntax-highlight</a> 
plugin.
The usage is extremely simple. Just add a shebang as the first line of your code example with the language you are using.
<pre><code>#!ruby
class Foo < Bar
 def hello
 puts "Hello World!"
 end
end
</code></pre>
The shebang is removed, and the code is outputted as:
<pre><code><pre><code class="language-ruby">class Foo < Bar
 def hello
 puts "Hello World!"
 end
end</code></pre>
</code></pre>
Now the code block is properly formatted for highlight.js to do its magic, and the code snippet will be properly 
highlighted.

WP-Markdown-Syntax-Sugar

WP Markdown Syntax Sugar is a simple plugin that works in conjunction with Markdown code blocks and highlight.js to properly format code.

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.
