Yes, it is feasible, but it is a burden to maintain. I am maintaining
two trees for my python projects because the API changes are
substantial. GTK enums are incompatible, so you may want to trees once
you are using them. I reccomend Trunk is gtk3, I backport some changes
to older gtk2 releases.
I have one case where the API is pretty similar and I decided to delay
the split. You can alias your imports so that most of the code thinks it
is working with GTK3.
try:
from gi.repository import GObject
from gi.repository import Gtk
from gi.repository import WebKit
except ImportError:
import pygtk
pygtk.require("2.0")
import glib as GObject
import gtk as Gtk
import webkit as WebKit
You may also need to check for cases of API change:
# Check for available API, avoid hasattr because it
# swallows keyboard and system interrupts.
method = getattr(thing, 'method_name', None)
if method is not None:
method(arg1)
