Yes, it's possible. You should be able to use DCOP to communicate with the
part, to the extent that meets your needs.
Otherwise, there are a couple of other approaches, depending on how Kate is
structured. One is to write sip bindings for the Kate part and supporting
lib(s), the same as PyKDE does. That's likely to be way more than most people
want (binding a complete application and supporting libs).
Another way is to write lightweight wrappers in C++ that expose only the
objects you want to manipulate. That's usually not too difficult.
A third way (works for things like kspread and maybe other koffice apps) is to
rewrite the application's front end to make it a Python application - the
koffice apps, for example, are all kparts with a front end that loads them
(in theory - in practice the division isn't quite that clean). That would
involve wrapping a few top level objects. I don't mean rewriting the entire
app in Python, just wrapping the higher level functions, for example, load
file, create new window, find & replace - the kind of stuff that's usually in
I've looked at doing bindings for KTextEditor (I believe it's in kdelibs?),
but for some reason have always decided not too. There is some stuff in kdeui
(find an replace, KEdit, etc) that allows you to do a simple editor pretty
