Subject Re: [SCXML] Actionscript SCXML engine
Date Sun, 30 Jan 2011 18:42:49 GMT
Hello Gavin!
It sounds like very ambitious goal. Go for it.

I don't know ActionScript but I should have syntax derived from
JavaScript (ECMAScript). There is already JS SCXML engine at
http://commons.apache.org/sandbox/gsoc/2010/scxml-js/ so you use it
like base or at least for inspiration.

God bless you!
Libor
