Here's a quick way to add syntax highlighting to code blocks in the monastery:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/hi
+ghlight.js/11.7.0/styles/base16/one-light.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.7.
+0/highlight.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.7.
+0/languages/perl.min.js"></script>
<script>
window.addEventListener( "DOMContentLoaded", ( event ) => {
  hljs.configure( {
    cssSelector: '.codeblock .codetext font',
    languages:   new Array( 'perl', 'html', 'css', 'xml', 'json', 'yam
+l', 'diff' ),
  } );
  hljs.highlightAll();

  /* If you use the free nodelet for only Javascript/CSS,
   * and not as a display area, then you can uncomment
   * the next line of Javascript.
   */
  // document.getElementById( 'Free_Nodelet' ).display.style = 'none';
} );
</script>
<style>
.codeblock .codetext font {
  white-space: pre;
  display: block;
  padding: 0.5rem;
  margin: 0.5rem 1rem 0.5rem 0;
  border: 1px solid #ccc;
  border-radius: 0.125rem;
}
</style>

You may want to double-check the CSS selector used because I think this may differ based on other settings you've chosen.

Also, you may wish to choose a different colour scheme. highlight.js (the syntax highlighter used) comes with a huge variety of colour schemes. Scroll down to the bottom of this page to find URLs for other options. (And previews are here.)

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
