This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



WP-Markdown-SyntaxHighlighter is intended to work with the wp-markdown and SyntaxHighlighter Evolved plugins as follows:

  • WP-Markdown can automatically use Prettify.js to format code, but if you prefer Alex Gorbatchev’s SyntaxHighlighter, this plugin will re-format the Markdown-formatted code blocks to be properly styled by SyntaxHighlighter directly or SyntaxHighlighter Evolved via plugin.
  • SyntaxHighlighter Evolved uses SyntaxHighlighter and additional extended functionality to display code blocks in an easily readable manner.

There are two methods of use:

  1. Add a #! line to your code example and specify the language (brush) only
  2. Add a #!! line to your code example and specify any/all supported parameters via a JSON object

Simple Method

To use, add a #! line as the first line of your code example with the language you are using:

class Foo < Bar
  def hello
    puts "Hello World!"

The #! is removed, and the code is reformatted as:

<pre class="brush:ruby; notranslate" title="">class One < Two
  def hello
    puts "Hello World!"

Full Method

To use, add a #!! line as the first line of your code example, with any of the supported SyntaxHighlighter parameters as a JSON object

class Foo < Bar
  def hello
    puts "Hello World!"

The #!! is removed, and the parameters are interpreted into a CSS class string as:

<pre class="brush: ruby; toolbar: true; highlight: [2,3,4]; notranslate">class Foo < Bar
  def hello
    puts "Hello World!"


  • Consider adding support to toggle ‘notranslate’


  1. Upload the wp-markdown-syntaxhighlighter folder (and its contents) to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Modify improperly formatted code blocks with your chosen #! or #!! formatting.
