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.

Advanced reduce logical condition according to operator precedence and priority

while ( (a = (b || true)) || (b != (a > 3) && b < 4)) { ... }

to :

while ( (a = b || true) || b != a > 3 && b < 4) { ... }
