title: Display link url in markdown
body: <p>I have a markdown file in which I use a link multiple times, for example:</p>
  
  <pre><code>This [website][an_awesome_website_link] is awesome.
  
  You will never use anything else than this [website][an_awesome_website_link].
  
  [an_awesome_website_link]: https://stackoverflow.com
  </code></pre>
  
  <p>Formatted, it looks like:</p>
  
  <blockquote>
    <p>This <a href="https://stackoverflow.com">website</a> is awesome.</p>
    
    <p>You will never use anything else than this <a href="https://stackoverflow.com">website</a>.</p>

  <p>I want to display the link url of <code>[an_awesome_website_link]</code> without having to write again the said url.</p>
  
  <p>For example, I want to have this, and write the url of stackoverflow only 1 time in my markdown file:</p>
  
  <blockquote>
    <p>This <a href="https://stackoverflow.com">website (https://stackoverflow.com)</a>.</p>
    
    <p>You will never use anything else than this <a href="https://stackoverflow.com">website</a>.</p>
    
    <p>Check out <a href="https://stackoverflow.com">https://stackoverflow.com</a> for more fun.</p>
  </blockquote>
  
  <p>Is it possible ? How ?</p>
