Looking at the Changelogs for EE 2.7.0 I see there is now:
Added Markdown plugin and field formatting option
…but I don't see any details in the documentation. Is there any information available on the new plug-in and how it works?
From the plugin file in EE 2.7:
This plugin parses text using Markdown and Smartypants. To use this plugin wrap any text in this tag pair:
{exp:markdown}
Text to be **parsed**.
{/exp:markdown}
There are two parameters you can set:
For basic syntax, EE is referring to http://daringfireball.net/projects/markdown/syntax
Also, PHP Markdown is being used, so anything you see here -- http://michelf.ca/projects/php-markdown/extra/ -- is available. Good for adding classes and ids, etc.
exp:markdown
