Hi Jake, Thank you for your help and you have done a good job. I am not very familiar with ECMAScript, it seems that ECMAScript is some kind of JavaScript. I do not think ActionScript is a superset of ECMAScript. ActionScript is a kind a Flex/Flash script languare, we usually use it to develop some kind of Flash application, a ball or a small guy move in the screen something. And it is a Object-Oriented language, just like JAVA and we can use it to parse XML document very convenient.
In Flash/Flex application, we usually write much state or transition relative code to control an object in the canvas, if we hava an ActionScript SCXML engine, i think it will improve our Flash/Flex develop progress. And i search this topic in Google and find some relative requests from developers, so i have this idea and post it here to expect more advises :-) 在 2011年1月30日 下午12:28，Jacob Beard <jbea...@cs.mcgill.ca>写道： > Hi Gavin, > > I've developed scxml-js, a SCXML-to-ECMAScript compiler as a part of > last year's Google Summer of Code.
