Overview

Generates HTML from Markdown.

It's particularly useful in conjunction with the Template post processor to generate a description from other selectors.

YAML usage example:

selectors:
 description:
   selector: section
   post_process:
     - name: template
       string: |
         # %s

         Price: %s
       methods:
         - self
         - price
     - name: markdown_to_html

Would e.g. return:

Section

Price: 12.34
