I could, but you ask all the right questions, so I can just answer those.

Yes.

It is the case, so "no". I read that last sentence as "can you use Python
to assemble existing components [written in e.g. C++]". While that is _a
part_ of the capability we're talking about, we are also talking about the
ability to have Python components act invisibly to the rest of Mozilla as
full-fledged XPCOM components (much like existing C++ components currently).
This is not unlike what one can do in PythonCOM currently in the Windows
world.

The former.

Correct.

That too. Both of those (really the same feature) require considerable
changes to the parser and to the DOM model, as documented in e.g.
http://www.mozilla.org/scriptable/agnostic.html. Again, that is part of our
long-term plan.

In the long term, yes -- but not in the short term. In the short term
you'll have to use some JS in XUL files, although it will be able to
reference and call and manipulate components written in Python outside of
the XUL.

I'll look into it, thanks for the pointer.

We're still working out how to proceed with respect to working with folks
outside of the company. I expect much of the discussion will take place on
existing Mozilla newsgroups.

Sorry, I'm unable to give a best guess at this point with any meat behind
it, especially when it involves integration with the main Mozilla tree, over
which we have no control.
While it's not a direct answer to your question, we are collecting email
addresses of those who want to be notified when Komodo is ready
(http://www.activestate.com/Products/Komodo.html).
I hope the above is helpful.

PS: Wouldn't it make sense to trim the main Zope mailing list from this
thread? I see it as being Mozilla-centric, not Zope-centric.

Would you please expand on the "make XPCOM components" task. By
this are you adding new components, written in Python, that will be
accessible through the XPCOM interface? Would these components be
constructed in Python from components interfaces that are accessible
through the XPCOM interface? If this isn't the case then is does this
simply mean that Python can be used to assemble chrome using existing
XPCOM components.
Are you doing this by wrapping the the interface to the XPCOM Type
Library or will you be parsing the XPIDL files directly. (Another
interesting approach is the way the ORBit-Python project reads CORBA
IDL files at run time and links directly to an ORBit ORB.)

By this do you mean that in the following XUL the value of "oncommand"
cannot be python code?
or are you talking about not being able to embed Python instead of
javascript as in the following:
function doCMD(el) {
v = el.getAttribute("value")
if (v == "New") alert('New clicked')
elsif (v == "Open") alert('Open clicked')
else alert('Close clicked')
}
...
Instead of using XUL to write the definition from the
first example or the definition in the second example will
it be possible to write the equivolent of the XUL completely in
Python? That is, will the planned interface make it possible to build
an XPCOM component based application, such as the Mozilla browser,
entirely in Python.
An interface between the Glade IDE and Mozilla has recently been
checked into Sourceforge. The documentation on MozGlade is weak.
The freshmeat announcment
http://freshmeat.net/appindex/2000/05/16/958529719.html hints at the
goal. The project looks like it might intersect with the goals of the
Komono IDE project.
Will there be a mailing list for the project? What is your best guess
on when the "make XPCOM components" capability will be available for
testing from the Mozilla CVS?
