Debugging SASS in Chrome

In Firefox, viewing the original SASS line number directly has been possible using Firebug and FireSass. Similar, or even better functionality has very recently arrived in the stable release of Chrome. I just tried this out and it works wonderfully. See here for instructions:

How to make Chrome understand the SASS/SCSS in your rails app

Don’t worry about the Rails stuff, these instructions work just as well for stand-alone SASS. If you’re using Compass like me, you need to set sass_options = {:debug_info => true} in the config.rb file of your project.

If you look at your css files after doing the above, you’ll see they are quite a mess. From a comment by Paul Irish in the above post I learnt better stuff is on its way thanks to the upcoming SASS 3.3, and Source Map support in Chrome:

Debugging SASS with Source Maps

Exciting times!
