We, the team of Qt developers at Nokia and INdT, would like to add a

API to JavaScriptCore as well, to allow application developers to

embed the JavaScriptCore engine into their applications.
We want to give developers the ability to introspect the
environment, inject
custom classes and call functions using a C++ API that uses Qt types
and has a
Qt-ish feel to it. Current releases of Qt come with such an API as
part of the
QtScript module, which however is based on an in-house developed
interpreter.
I think this sounds like a wonderful project, but it seems to be so
heavily tied to the various Qt infrastructure. Consequently, I wonder
if the general utility of this work will warrant being housed in the
WebKit repository.
A few similar projects exist externally (or are seeking approval to be
added) such as the explosive GObject-based interface, the ever-
shifting COM-ish interface, and an external project seeking to create
a simple API to use with WebKit.
I wish there were sufficient dynamic features in C++ to make it
possible to write code as simple and elegant as those in the Qt
example you linked. However, until I port my application to Qt I'm
afraid the various additional dependencies make it somewhat unlikely
that I would ever make use of it.
I do wish there was a C++ library that would make it easier to write
JS<->C++ code. Having to write the various C 'thunks' to move
parameters in and out of JavaScript is boring and maintenance-intensive.
This is (of course) not a problem limited to JavaScriptCore; every
extension language I can think of has similar issues.
