iirc there are some issues with the Apache license in GPLv2. GPLv3 however is fine with the Apache license.
As for dropping JSMin... I never really liked Crockford anyways, nor JSMin... so I don't really have any problem. I also don't like the idea of maintaining what's essentially a local fork from the upstream, so if this is a performance improvement and eliminates the need to fork something to get it to do what we want... perfect. Personally I always had a preference towards YUI's minifier. I haven't quite jumped onto closure just yet... in the early days I wasn't sure about trusting it to not introduce edge cases into code (since it basically does some rewriting of code above what other minifiers do and I wasn't sure about it's implementation. ~Daniel Friesen (Dantman, Nadir-Seen-Fire) [http://daniel.friesen.name] On 11-01-20 06:57 PM, Michael Dale wrote: > As mentioned in the bug, it would be nice to have configurable support > for the closure-compiler as well ;) ( I assume Apache licence is > compatible? ) > > Has anyone done any tests to see if there are any compatibility issues > with SIMPLE_OPTIMIZATIONS with a google closure minification hook? > > --michael > > On 01/20/2011 04:13 PM, Trevor Parscal wrote: >> For those of you who didn't see bug 26791, our use of JSMin has been >> found to conflict with our GPL license.
