Semantic markdown blocks

Elements such as <aside>, <section>, and <article> cannot be expressed in markdown unless you create a block of HTML content. Unfortunately, this means child markdown is not converted to HTML. For example:

markdown input

<aside>
See also:

* [link one](#one)
* [link two](#two)
* [link three](#three)
</aside>

renders the HTML exactly as shown.

The following processContent hook function translates ${ tag } … ${ /tag }, where tag can be aside, section, or article.

publican.config.processContent.add( data => {
  data.content = data.content
    .replace(/{\s*(\/{0,1}aside|section|article)\s*\}/gi, '<$1>')
    .replace(/<p><(aside|section|article)><\/p>/gi, '<$1>')
    .replace(/\n<(.+?)><(aside|section|article)>\s/gi, '\n<$2><$1>')
    .replace(/\n<\/(aside|section|article)><\/(.+?)>\n/gi, '</$2></$1>\n');
}

Converting <aside> tags to use { and } brackets in the example above now outputs:

HTML output

<aside>
<p>See also:</p>

<ul>
  <li><a href="#one">link one</a></li>
  <li><a href="#two">link two</a></li>
  <li><a href="#three">link three</a></li>
<ul>
</aside>
