Overview

Renders a cleaned content node as Markdown. Expects the article-shaped markup that comes out of extraction; it is not a general-purpose HTML-to-Markdown converter.

The formatting decisions live in small hook methods (heading, link, image, ...) so TextRenderer can subclass this and strip the syntax.

def render(node)
  # Route through render_block so a root that is itself a block
  # element (a ul, a blockquote) gets its block treatment; generic
  # containers and fragments fall through to render_blocks.
  output = node.element? ? render_block(node) : render_blocks(node)
  output.gsub(/\n{3,}/, "\n\n").strip
