Yeoman + Compass Sprites

Setup

generator-webapp has support for compass out of the box. However, in order to use one of my favorite features of it — sprites and the image_url helper — you have to make some adjustments to the Gruntfile.

Let's assume you use a SASS stylesheet like this one:

@import "design/*.png"

jQuery.fn.selectTimeZone = function() {
 var $el = $(this[0]); // our element
 var offsetFromGMT = String(- new Date('1/1/2009').getTimezoneOffset() / 60); // using 1/1/2009 so we know DST isn't tripping us up
 if (offsetFromGMT[0] != '-') {
  offsetFromGMT = '+' + offsetFromGMT; // if it's not negative, prepend a +
 }
 if (offsetFromGMT.length < 3) {
  offsetFromGMT = offsetFromGMT.substr(0, 1) + '0' + offsetFromGMT.substr(1); // add a leading zero if we need it
 }
 var regEx = new RegExp(offsetFromGMT); // create a RegExp object with our pattern
