Some more questions on QSA
Message 1 in thread
Hi,
I got some more questions on QSA:
1) What is planned for 1.2.1? When is it out?
2) Is QSA based upon some other ECMAScript-Implementation or is it newly
built from ground up?
3) I compiled QSA against Qt 4.1.0 using VS2005 without Qt3 support. The
resulting DLL has 700 kByte, in release mode. Isn't that somewhat big,
considering a spidermonkey DLL is only about a third of that, but has to
implement everything by itself, while QSA certainly uses Qt (on regexes,
strings etc.)

Within a few weeks. It is a bugfix release so it contains the fixes
previous mentioned on this list and other issues. It does not contain a
new features, save for a few minor improvements.

Its was originally based on KJS which is the JavaScript implementation
running in Konqueror and Safari, but they diverged several years ago and
Trolltech is maintaining its own modified version.

Not really ;-)
QSA also provides a complete binding layer to Qt, with signals/slots,
QVariants, ObjectFactories, etc, in addition to the builtin features
that are defined in the ECMAScript standard. For the built in types we
still have to implement some code since the API's in QSA differ from
those in Qt on several places.
