# Title: Simple Code Blocks for Jekyll
# Author: Brandon Mathis http://brandonmathis.com
# Description: Write codeblocks with semantic HTML5 <figure> and <figcaption> elements and optional syntax highlighting — all with a simple, intuitive interface.
#
# Syntax:
# {% codeblock [title] [url] [link text] %}
# code snippet
# {% endcodeblock %}
#
# For syntax highlighting, put a file extension somewhere in the title. examples:
# {% codeblock file.sh %}
# code snippet
# {% endcodeblock %}
#
# {% codeblock Time to be Awesome! (awesome.rb) %}
# code snippet
# {% endcodeblock %}
#
# Example:
#
# {% codeblock Got pain? painreleif.sh http://site.com/painreleief.sh Download it! %}
# $ rm -rf ~/PAIN
# {% endcodeblock %}
#
# Output:
#
# <figure role=code>
# <figcaption><span>Got pain? painrelief.sh</span> <a href="http://site.com/painrelief.sh">Download it!</a>
# <div class="highlight"><pre><code class="sh">
# -- nicely escaped highlighted code --
# </code></pre></div>
# </figure>
#
# Example 2 (no syntax highlighting):
#
# {% codeblock %}
# <sarcasm>Ooooh, sarcasm... How original!</sarcasm>
# {% endcodeblock %}
#
# <figure role=code>
# <pre><code><sarcasm> Ooooh, sarcasm... How original!</sarcasm></code></pre>
# </figure>
