CSSStyleSheet.toString()

[NV]

Ability to serialize CSSStyleSheet object into CSS string.

CSSOM.parse("body {color: black}").toString()
-> "body {color: black}"

It might need a few options, such as indent or propertiesSeparator. Not sure about it yet.

Ah, bummer...

Even without indentation, it should be feasible. I believe my usecase (parse/modify/serialize) is common enough to justify having this.

At the moment I can't even inspect it:

var p = CSSOM.parse("body {color: black}")
console.dir(p)

...I get

I can't reproduce TypeError: Array.prototype.toString is not generic in Chrome 9.0.587.0 dev, Safari 5.0.2 (6533.18.5) and Firefox 4.0b6. What browser do you use?

[frank06]

Ah, sorry. Using it in node.js (weird, should behave like Chrome - but i don't know which V8 versions they're running).

[NV]

I see. I'll get reed of __proto__ so it will be fixed soon. It might be a node.js REPL's bug, though.

[frank06]

When you fix it, would this output the serialized CSS tree – or just 'don't break'?

By the way, I got the is not generic bug calling the library in a program, not the REPL.

CSSStyleSheet.toString has been landed. Try it on demo page.

Node.js bug should be fixed as well. 0eb3d4e. No idea what was causing it.

Wow, excellent, thanks! I'll let you know how it goes.
