execution of javascript in a browser is another limiting factor.
speed, error reporting to just name two problems.
it would be easy to load most javascript into a QScript engine
previously loaded with mootools, prototype or other favorite
wrapper, coffee script or whatever then evaluate any node
or selected text as can now be done with python & execute script.
not sure how completely pyqt wraps QScript. I have been using
jsbn large integer javascript run inside QScript.
there are some things to notice, most javascript, especially
projects started over a few years ago, expect to be run in
a browser so they expect things like alert("") to work.
prime the engine with something like:
function alert(msg){
throw(Error(msg));
}
of course, an actual popup could be done as well.
sometimes they run code to determine which browser and
change their code on the fly these kinds of things would
have to be commented out or made to recognize QScript somehow.
QScript is mostly compatible but not 100%.
all problems that could be worked out if anyone cared.
QScript has/can be given access to all Qt slots & signals.
there are many more potential programmers of javascript looking
for a fun tool in Leo than there are python programmers.
http://altjs.org/ has a bunch of ports, forks and standalone engines
links.
also check out JSHint, a true fork of JSLint.
I can't recommend a test harness project, there are many, I run
tests outside using javascript to provide the answers.
