Markdown Shortcode

Damn simple [markdown]#via shortcode[/markdown] for wordpress.
This plugin uses parsedown and highlight.js. Zero configuration.

Write this into the editor:

[markdown]  
#h1

h2

text  
____source code (two ore more underscores will be replaced by empty spaces)  
____source code (two ore more underscores will be replaced by empty spaces)  

    `javascript
source code
    `
[/markdown]

and the shortcode content will be parsed with parsedown. Syntax highlighting will appear for the source codes.

This plugin is available at github, too.
