Rainbow

Rainbow is a code syntax highlighting library written in Javascript.

It was designed to be lightweight (1.4kb), easy to use, and extendable.

It is completely themable via CSS.

Quick Start

  1. Include some markup for code you want to be highlighted:

    <pre><code data-language="python">def openFile(path):
        file = open(path, "r")
        content = file.read()
        file.close()
        return content</code></pre>
  2. Include a CSS theme file in the <head>:

    <link href="/assets/css/theme.css" rel="stylesheet" type="text/css">
  3. Include rainbow.js and whatever languages you want before the closing </body>:

    <script src="/assets/js/rainbow.min.js"></script>
    <script src="/assets/js/language/generic.js"></script>
    <script src="/assets/js/language/python.js"></script>

Extending Rainbow

If you have a language specific pattern that you want highlighted, but it does not exist in the language syntax rules you can add a rule on your page.

Let's say for example you want to reference PHP's apc functions. You can include the php language then in the markup on your page add:

<script>
    Rainbow.extend('php', [
        {
            'matches': {
                1: 'support.function'
            },
            'pattern': /\b(apc_(store|fetch|add|inc))(?=\()/g
        }
    ]);
</script>
