KJSEmbed and QtScript

KJSEmbed and QtScript aim to offer very similar functionality to
applications. This presentation will discuss the similarities and
differences between the two. I hope to illustrate the similarities in
the approach of KJSEmbed for Qt 4 with that used by QtScript whilst
highlighting the areas where the libraries differ. I will also compare
the performance of the libraries when performing common tasks (for
example the start-up speed of the interpreters and the run-time speed
when executing scripts).

The Qt 4 version of KJSEmbed uses a heavily template based
implementation developed by Ian Geiser. QtScript is similar, but uses
the Qt meta-type infrastructure and some moc enhancements to achieve
the same goal. Both libraries provide simple to use facilities for
access the properties, slots and children of QObjects with almost
identical APIs.

In this presentation I hope to provide enough information for the KDE
development community to make an informed choice about which framework
will better suit the requirement of pervasive scripting in KDE 4.
