Feature: Add YUI-style optimisations for compressed CSS output

[ghost]

Just to name a few optimisations that the YUI compressor handles but SASS doesn't:

• Removing the leading zero from floating-point numbers (0.5em -> .5em)
• Removing the units from 0 (0px -> 0)
• Removing spaces in the middle of font lists ("Font 1", "Font 2" -> "Font 1","Font 2")

...does that really provide an enormous speed boost to the loading time ?

I'd be interested in this. Every little bit helps, though a linter seems a bit out of scope. https://csslint.net/

In hindsight, having a linter does seem a bit out of scope, although things like removing units from values can reduce file size by quite a bit if you have a lot of definitions. Stuff like condensing border definitions into one rule is kind of out of the scope of SASS.

Don't get me wrong, I still very much want that kind of compression and minification, along with linting. In fact, I have been trying to handle this with Grunt or Rake tasks lately, so I'm glad this discussion is happening now (yes, I use and am aware of the compressed style of output). What we're talking about is pushing Sass beyond compression into linting. Maybe it could fit into the goals of Sass, I dunno. I think the discussion would have to be with a wider audience.

Maybe it could be an option in Compass? + @chriseppstein

Linting could also be something that could be a part of a GUI app like Codekit. Thoughts @bdkjones?

CodeKit already offers the compressed option for Sass output.

Is there a good Sass lint tool available?

Ooh now that's a good question.

[kevinSuttle]

I really thought there'd be more traction and opinions on this.

A quick search didn't yield much other than the following:

+1 on remove leading zero.

The other optimizations look good as well. :)

@Undeterminant It looks like the font list compression is already present in master. If I've misunderstood, please add another example and I'll take a look.

This bug was reported 2 months ago, so, it may have silently been fixed with a code update. Either way, if it's in master, you can just accept it as implemented.

Any updates re: Sass/SCSS linting?
