Fabio, Good comments.
I guess this means that we should work toward a user selectable
autocompletion. We can build upon what we have now of course as an
initial cut, and we can experiment with spawning a CPython interpreter
to run the same code introspection package. Is that how everyone else
reads it?
Parthoum, if you would prefer look into how we might spawn a CPython
interpreter and run the same introspection code we are using now (which
is in the jythonlib.jar), I could actually move into trying the new
project wizard. Can you let the group know if you'd like to attempt
that effort as soon as you can, so that we can adjust our planning
accordingly.
Parthoum, I am looking at your thesis features list, and I would like
to help you get as much of tht done as possible; I notice that
autocomplet is on it as well, so maybe it's a good plan for you to get
involved in that way. By the way, we still need to code autocompletion
for an opening round brace "(", I can look at that, in the
PyCompletionProcessor code. The introspector I based this on _should_
handle that case; I will find out why it's not :-)
