Expected Behavior

It should give me the full ast so that I can print url() center center no-repeat black back

Actual Behavior

Right now, it only gives me url( black and unbalanced: 1

How can we reproduce the behavior?

Just parse this block of code

I just want to say I'm extremely impressed by your projects @shellscape, only 4 small issues have been found while running it through all the Facebook codebase, this is awesome! Thanks a ton for all your work <3

[shellscape]

Thanks very much for the kind words! That's very humbling and exciting to know!

(Obligatory comment about updating to at least Node 4.6.0. That's our minimum version supported at the moment.)

First question - is an empty url() function valid per spec? That should probably be answered at some point.

It's definitely misbehaving. I'll see what I can do. Might be after the holiday weekend and well into next week; big things going on in life at the moment.

I have no idea if it's spec compliant :p We've got two instances in our codebase

2a2e99e should fix this. the myriad of conditionals surrounding the url function was causing it, didn't anticipate zero params.
