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:

<h1>Section</h1>

<p>Price: 12.34</p>
