Qt Script For Applications 1.0 Released Today
hpj writes "Trolltech today released QSA. An ECMA based scripting extension to Qt (On which KDE is based) which allows easily adding scripting support to Qt (And in extension KDE applications). It is licensed like Qt under GPL as well as commercial licenses for Windows, Mac and X11 for those GPL is not suitable."
AFAIK, KJS is based on ECMAScript Edition 3 (implemented in JavaScript 1.5 and JScript 5.5). QSA is based on the forthcoming Edition 4, which is way different from the previous version. (Edition 4 is implemented in JScript.NET and the yet-to-be-released JavaScript 2.0).
