我们正在积极地研究Google的[V8 JavaScript引擎](http://code.google.com/p/v8/),以将其应用到Qt中。由于法律方面的原因,之前我们不得不把工作放在幕后进行,但现在是回归的时候了:
[http://qt.gitorious.org/qt/qt-script-ng](http://qt.gitorious.org/qt/qt-script-ng)
目前这是一个完整的Qt克隆。你可以在[QtScript wiki](http://developer.qt.nokia.com/wiki/Category:Developing_Qt::Qt_Script)上找到更多关于此项目的信息。我们还为JavaScript/Qt开发创建了[邮件列表](http://lists.qt.nokia.com/mailman/listinfo/qt-script),和一个FreeNode上的IRC频道,#qt-script。如果你对Qt的JavaScript(在QML, QtWebkit或者自定义程序的嵌入)的集成(的未来)有兴趣,欢迎参与!
基于V8的后端的状态是,我们仍有一部分QtScript的API未实现,以及自动测试失败([QTBUG-17640](http://bugreports.qt.nokia.com/browse/QTBUG-17640")),但QtScript和QML的一些例子和演示程序已经可以运行。除了与当前的Qt在行为上兼容之外,我们还需要确保在V8支持的Qt成为可选解决方案之前,C++/JS层不存在任何性能缺口。如笔者在[前面发表的文章](http://labs.qt.nokia.com.cn/2011/02/10/resolving-qtscripts-legacy-apis/) ([英文原文](http://labs.qt.nokia.com/2011/01/20/resolving-qtscripts-legacy-apis/")) 中提到的,我们同时着眼于修剪目前臃肿的API,以便切换(到V8)更可行。
