lightAHK
This (fun) project uses Prism.js to make a really lightweight syntax highlighting solution for AutoHotkey. This Syntax highlighting javascript lacks autohotkey keywords and simply relies on regex to highlight code. Any valid AHK code will thus highlight correctly. See demo
Note - Highlighting may encounter issues due to its total reliance on regex.
Prism also has full AutoHotkey syntax highlighting. Get it at their download page. This highlighting script for AutoHotkey weighs upto 14 times less than that distributed with Prism. It is recommended to use this highlighting script only when you're sure the code is correct. Small chunks of code usually don't have typos or hidden issues and thus perfect for usage with this script.
The whole highlight package = 850 + 4111 + 1525 = 6.4kb
Using
Include these 3 files in the <head> tag.
<head>
<script src="components/prism-core.min.js"></script>
<script src="components/prism-ahk.min.js"></script>
<link href="themes/prism-github.min.css" rel="stylesheet" />
</head>
Then use language-autohotkey class in code tag for highlighting.
<pre><code class="language-autohotkey">
;Ahk code starts
#SingleInstance Force
msgbox Starting
msgbox % "Loading Databases"
</code></pre>
More themes and docs
Please get more themes from Prism's website. As this project uses Prism.js and is nothing on its own, Prismjs.com is the best resource for more information. If you need more help, open an issue.
