new the-yui-compressor for js

[Animal]

Yes, but

<span style="Dr. Szell">Is It Safe?</span>

and does it decompress fast (read: fast + low cpu usage) on a normal (read: non-development) machine?

AFAIK, dean edward's packer at max js compression also results in max decompression time.

I'm gonna stick with the yuicompressor and gzip file compression on the fly. It does want i need it to and i can sill make out some of the functions for quick debugging.

agreed. i'm sticking with yuicompressor too.
tried various combinations of ShrinkSafe + Packer before, but they pale in comparison to yuicompressor.

ok, i run into problems with Dean Edwards 's Packer. Everything worked well: Layouts, dialogs, Accordion - but grid failed.

Dean Edwards' Packer mungs the semantics of the code in some situations.

Check Julien Lecomte's blog entries about the yui compressor.

It does seem like YAHOO is the best option.

[steffenk]

does mootools use Dean Edwards' Packer ? May be they only linked to it.
I think YUI-compressor works best atm. Anyway i will inform Edwards, may be he fixes something.

be careful when compressing with the latest yuicompressor-2.2.1.jar.

one new feature was added

YUI Compressor 2.2.1, 2007-09-25
--------------------------------

+ Optimize quote escaping in JavaScript string literals by using the best quote
character (' or " depending on the occurrence of this character in the string)

which for some strange reason, turned this line in ext-all-debug.js

document.write("<s"+'cript id="ie-deferred-loader" defer="defer" src="/'+'/:"></s'+"cript>");

into

document.write("<s"+"cript id="ie-deferred-loader" defer="defer" src="/"+"/:"></s"+"cript>");

which killed the minified script.

i've tried to inform the author of this. let's hope he replies soon.

Does anybody have expierience with ESC ? A friend of mine does all his javascript with this compressor, see his page

did some more testing.
this works (i.e. yui-compressor-2.2.1 doesn't mess up when minifying ext-all-debug)

document.write("<s"+"cript id='ie-deferred-loader' defer='defer' src='/"+"/:'></s"+"cript>");

but the minified version gets cleverly optimised to

document.write("<script id='ie-deferred-loader' defer='defer' src='//:'></script>");

looks like the only way to preserve the original string is to do this

document.write(["<s",'cript id="ie-deferred-loader" defer="defer" src="/','/:"></s',"cript>"].join(""));

@jack/brian, any thoughts?

scratch all that.
yuicompressor-2.2.2 is out.
