How to use

Head over to the releases page and grab the minified version of the Rego syntax definition file (rego.min.js or rego.es.min.js). Include it in your HTML file, and use the language-rego class for the <code> block you want to highlight:

<!DOCTYPE html>
<html>
<head>
  <title>Highlight.js Rego Demo</title>
  <link rel="stylesheet" href="path/to/theme.css">
  <script type="text/javascript" src="path/to/highlight.min.js"></script>
  <script type="text/javascript" src="path/to/rego.min.js"></script>
  <script type="text/javascript">hljs.highlightAll();</script>
</head>

<body>
  <pre><code class="language-rego">
# METADATA
# description: Your Rego policy here!
package policy

default allow := false

allow if {
    # ..conditions..
}
  </code></pre>
</body>

</html>
