Kevin and Rowland,

Attached is the latest version of PyCrust. If you look in the Demos folder
you will see an application called PyCrustMinimus.py which is a bare minimum
application using PyCrust. It should be pretty easy to figure out from this
example how to integrate PyCrust into PythonCard. Do you guys want to do the
integration or do you want me to do it?

The files that should be copied into the PythonCard folder are the
following:

pseudo.py
PyCrustEditor.py
PyCrustInterp.py
PyCrustShell.py
PyCrustVersion.py

My thought on how to do the loading would be something like trying 'from
PyCrust.PyCrustShell import Shell' and if that failed then 'from
PyCrustShell import Shell'. That way PythonCard would load the Shell from
the users PyCrust package if they had PyCrust installed or directly from the
current directory (proto) if they did not have PyCrust.

Then we need to decide how we want to expose PythonCard to the shell. Here
are two possible ways: add an object to the sys module's namespace or add an
object to the interpreter's local dictionary. In PyCrust.py I do:

def main():
    import sys
    application = App(0)
    sys.application = application
    application.MainLoop()

Then inside the shell you can do:

>>> import sys
>>> sys.application.whatever
>>> sys.application.whatever.something
>>> sys.application.whatever.someaction()

This is nice in that the user can drill down through whatever the
application knows about. The other approach would look something like the
following wherever the Shell object first gets created:

self.shell = Shell(editorParent=self)
self.shell.interp.locals['whatever'] = whatever

The result of this is that inside the shell the user can type dir() and
'whatever' will be listed, without having to import the sys module. They can
then do:

>>> whatever.something
>>> whatever.someaction()

So it kind of depends on what we'd like to expose and how much we want to
"pollute" the local namespace by loading it up with stuff.

Let me know what you guys think and what I can do to help.

Subject: send me your latest files

Let's try and get pycrust integrated today.

What are the minimum files necessary? These would be the ones I would add to
the proto directory in the release distributions so someone doesn't have to
set their PYTHONPATH to use PyCrust and PythonCard.

Complete file list if someone wants to have PyCrust in its own directory and
set the PYTHONPATH.

Can you do an example screenshot for PyCrust as well as a text dump showing
off trying stuff out while running the Proof or another sample? This part
can be done once we have the integration done.

We want to remember position and size of the Message Watcher, PyCrust,
Properties editor, etc. We could either do that by saving the info whenever
a move or resize event happens or try and do it during the application
close, but I'm not sure about the hook for the latter.
