Fenced Code Extension for Python Markdown
=========================================

This extension adds Fenced Code Blocks to Python-Markdown.

>>> import markdown
 >>> text = '''
 ... A paragraph before a fenced code block:
 ... 
 ... ~~~
 ... Fenced code block
 ... ~~~
 ... '''
 >>> html = markdown.markdown(text, extensions=['fenced_code'])
 >>> html
 u'A paragraph before a fenced code block:\\n<pre><code>Fenced code block\\n</code></pre>'

Works with safe_mode also (we check this because we are using the HtmlStash):

>>> markdown.markdown(text, extensions=['fenced_code'], safe_mode='replace')
 u'A paragraph before a fenced code block:\\n<pre><code>Fenced code block\\n</code></pre>'
 
Include tilde's in a code block and wrap with blank lines:

>>> text = '''
 ... ~~~~~~~~
 ... 
 ... ~~~~
 ... 
 ... ~~~~~~~~'''
 >>> markdown.markdown(text, extensions=['fenced_code'])
 u'<pre><code>\\n~~~~\\n\\n</code></pre>'

Multiple blocks and language tags:

>>> text = '''
 ... ~~~~{.python}
 ... block one
 ... ~~~~
 ... 
 ... ~~~~.html
 ... block two
 ... ~~~~'''
 >>> markdown.markdown(text, extensions=['fenced_code'])
 u'<pre><code class="python">block one\\n</code></pre>\\n\\n<pre><code class="html">&lt;p&gt;block two&lt;/p&gt;\\n</code></pre>'
