Update: Have you heard of SyntaxHighlighter? It’s pretty cool. I like that it adds little controls for popping the code out into a new window in plain text and that it has line numbers. However, I think that these days I prefer CodeColorer. Anyway, I still have this deployed in some places, and I figure SyntaxHighlighter lovers might find it handy. In case I want to come back to in in the future, I’ve created a project on GitHub, Lazy Brush Loader for SyntaxHighlighter to manage it, so check that out if you’re interested.
Please let me know if this helped you or if you find any problems with it. Thanks!
N.B. You can only pass the brush. No other arguments.
Just include the stylesheets and the core JavaScript files.
<link rel="stylesheet" type="text/css" href="/js/SyntaxHighlighter/styles/shCore.css" />
<link rel="stylesheet" type="text/css" href="/js/SyntaxHighlighter/styles/shThemeDefault.css" />
<script type="text/javascript" src="/js/SyntaxHighlighter/src/shCore.js"></script>
<link rel="stylesheet" type="text/css" href="/js/SyntaxHighlighter/styles/shThemeDefault.css" />
<script type="text/javascript" src="/js/SyntaxHighlighter/src/shCore.js"></script>
Then include this script:
/* Add document.getElementsByClassName to IE */
if (!document.getElementsByClassName) {
document.getElementsByClassName = function(className) {
var all_elms = document.getElementsByTagName('*');
