# 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 class='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 class='code'>
|
|
# <pre><code><sarcasm> Ooooh, sarcasm... How original!</sarcasm></code></pre>
|
|
# </figure>
