Take a look at toscawidgets.genericfunctions (has no dependencies with TW at all). It has a custom combiner that adds a "priority" argument to when() (and before(), around() and after()) which greatly simplifies writing rules since you don't need to make one of them more specific to resolve ambiguities. For rules having the same priority it behaves in the same way as the standard combiner. The tests, at tests/test_genericfunctions.py, might shed a light on how it's used. It's been serving me well for some time :) Alberto --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
