WP Markdown Syntax Sugar works in conjunction with plugins such as wp-markdown and wp-highlight.js. Markdown is fantastic markup for easily writing blogs, and highlight.js 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 wp-markdown-syntax-highlight plugin.
The usage is extremely simple. Just add a shebang as the first line of your code example with the language you are using.
#!ruby class Foo < Bar def hello puts "Hello World!" end end
The shebang is removed, and the code is outputted as:
<pre><code class="language-ruby">class Foo < Bar def hello puts "Hello World!" end end</code></pre>
Now the code block is properly formatted for highlight.js to do its magic, and the code snippet will be properly highlighted.
