Hacking at 0300

Update: I no longer (2012-08-05) use Chili; I've switched to Prism.

I like the idea of syntax coloring, so let's see if Chili works:

alert('Hello, world');

and another: <div>Hello, <em>world</em></div>

I'm trying to be as HTML5-compliant as possible, at least in the sense of using their standards rather than making up my own, so the Chili setup I'm using is:

    $.extend(ChiliBook, {
        automatic: false,
        codeLanguage: function(el){
            // use the HTML5 language class
            var recipeName = /language-(\S+)/.exec(el.className);
            return recipeName ? recipeName[1] : '';
        }
    });
    $(function(){
        $('code[class*=language-]').not($('pre code')).chili({lineNumbers: false})
                                  .otherwise().chili({lineNumbers: true});
    });

 

Sweet! The idea of the above code is to look for a class that starts with "language-" and use that as the recipe for Chili (rather than Chili's built-in way of taking the entire className). It also assumes that any code in a pre element should have line numbers, and anything else should not. It uses the cute and brilliant otherwise plugin from http://groups.google.com/group/jquery-en/browse_thread/thread/6be2a127822a108d.

Update: It looks like line numbering works only intermittently. Oh well; I won't fix it.
