Thanks for your fix.
I'll test it and integrate it quickly.

I discover some small issues on this tool, especially when I try to apply it on the jQuery library.

At first, the variable name generation fails on a 2-digits generation.

For example, it starts at "be" instead of "ba" and go out of usable character range (attempt to use variables like "b€" or "b{").

This can be quickly fix on the line 535 of Jsxs.php file:

( $c < 36 ? chr($c + 97) : chr($c + 65) )

by using this code:

( $c < 36 ? chr($c + 87) : chr($c + 29) )

You see that it is just a incorrect range usage, nothing else...

Also, the second bug is really more complicate.

The compatibility option break some code (especially the jQuery library) by adding a semi-colon where it should not.

I have found it on some declarations like "{code}(),", that turns to "{code};(),".

Hopefully, this option can be deactivated and everything works fine without.

NOTE: on jQuery 1.5.2, look for the string:

return d}(),e="then done fail isResolved

You will see than after transformation it becomes:

return d};(),e="then done fail isResolved

... oups

Thanks for this nice tool.

Well, it's not that hard if you use lookbehind assertions and/or conditional subpatterns. I just learned about your project, so if you could point me how I can help (is it hosted on GitHub?), I'd gladly try to fix that.

Cheers.

There is a bug for the "do-while" statement with the compatibility option. This append because it's very hard to detect difference between "do-while" and only "while". I'll try to fix it in the next release.

Thanks you for debugging :)

Hey, Xorax.
d'oh. I really missed a semicolon there (and in some parts of the code). Now, there are semicolons and I just tested again.

Now, for some reason, it's adding a semicolon to a do{} block; so the interpreter is now asking for a while statement.

note: i just removed this semicolon and the compressed script is working perfectly. And, regardless of this little problem, this is now the official compressor of my JavaScript project, since it did the best job with compression. Thanks. ;)

@Evandro Myller
After testing, I think it's missing semicolumn before break in your code (yes, in javascript standard, it's not required if there is end of line after it)

@Kyle Simpson
There are many differences. Soon I'll write a table comparaison between JSXS and the other tools.
