Fast Code Prettify

This super small Wordpress plugin ensures Google Prettify syntax for Jetpack Markdown & Fenced Code Blocks.

In a nutshell, it enables syntax highlighting of your Markdown code.

• Updates JetPack's Markdown fenced blocks HTML to unified format:

  <pre class="prettyprint"><code class="language-bash">...

  From:

  <pre><code class="bash">...

  Or:

  <pre><code>...

• Includes Google Prettify from CDNJS when needed, does so with async attribute of script tag.

• Comes with no GUI for settings, very lightweight and does its thing to syntax highlight code!

Usage notes

• JetPack fenced block Markdown is specified like this:

    ```css
    p.warning { color: red; }
    ```
  

• Defaults to bash when no language specified in fenced block. You can also use 4-spaces separated code blocks instead of backticks to highlight using default language.

• You must include the prettify CSS to your theme's style.css. It is too small to be dynamic. Also Wordpress doesn't have native way to dynamically include CSS without affecting performance.

Caveats

• I will not make default language as a setting. I don't want to deal with silly Wordpress options mechanism and I don't want to have any database impact. The plugin is simple for efficiency. (Goodbye bloatware plugins)
