A SYNTAX HIGHLIGHTER EXTENSION FOR DECK.JS

from: http://niftybits.wordpress.com/2012/01/09/a-syntax-highlighter-extension-for-deck-js/

So for the past few hours, have been playing with Deck.js . I like the idea of a web based presentation format rather than a blob like powerpoint. At the same time, I’m a bit circumspect too – given the state of the tools. At least for my use, there’s really no burning need that powerpoint can’t solve (though I get the shivers everytime I have to do a presentation). All the web based/HTML5 seem raw at the moment on some much needed features (slide notes, slide prints, scaling issues etc).

Anyway, after a few minutes on Google and StackOverflow, decided to give Deck.js a spin. Deck.js is really nice and you should take a tour if you haven’t done so. So finally, after giving the online presentation and the introduction a try, downloaded the latest to give it a more thorough spin. As usual, one of the first things was embedding code snippets and I thought it would be nice to
