I am using YUIC, and it’s working fine.
I am wondering if it could replace

var a = new Array()
with
var a = []

as suggested by JSLint

Thanks,

Thomas P

Hi,
Would it be possible to add 1 more option? I’m thinking about some kind of automatic naming of the output.
the standard one is: -o filename.ext
I’d love to find: -oo filename-min.ext or anything like that.
It would help a lot to set some automatic tasks in windows registry, or any IDE…
Thanks anyway for your work
Ben

WebKit (Safari 3) introduces some support for media queries. For example this works:
@media all and (min-width:0){html{color:red}}
while omitting the space after “and” like that:
@media all and(min-width:0){html{color:red}}
doesn’t.
YUICompressor removes it. I wonder if you consider this as a bug only for the WebKit developers or something to adjust YUICompressor to.

@Jesse
I’m seeing the same problem, where \r and \n are being interpreted out and giving me a line break. Any insight as to what specifically was causing this? I’m seeing this on the 2.2.4 build.

Sorry for an informal way of submitting a feature request – is there a bug track for the compressor? I haven’t found an appropriate category on Sourceforge YUI project. Would it possible to shorten “true” to “!0″ and “false” to “!1″ (without quotes)? It works in all browsers that I’ve got, but you probably test against more.

This is why the option --preserve-strings (which makes the compressor leave string literals intact) was introduced in version 2.2.3.

Hm, I am wondering if it this change:

+ Remove line terminator after escape in string literals.

in the latest 2.2.5 release should be changed to inserting a escaped newline character, instead of just removing the newline. Because right now you’re changing the behavior of a script (shortening string literals – what if a script checks for a specific string length?), that’s IMO something a compressor should never do.

It was something on my classpath that was causing the problem. I changed my ant task around a bit and it works flawlessly now. Sorry about the bogus report.

Sorry, I did some further testing and discovered that it's somehow related to my environment. I did some experimenting and found that 2.2.4 works perfectly for me if I run it from the command line 'java -jar yuixxxxx'. If I run it as an ant task, however, this input '(?:)((\n|\r|.)*?)(?:)' results in a line break in the generated file. It's very odd that the 2.1 version does work for me from the ant script.

@Jesse

With version 2.2.4, the following:

var s = “xxx\nyyy”;

is compressed to:

var s=”xxx\nyyy”

I don’t see any problem with line-breaks. With version of Java are you using? Are you redirecting the standard output, or are you using the -o option?

Thanks
