Could repoze.what 1 be (easily) modified to track its predicate decorators?
For example, suppose:
def predicate(value):
def decorate(func):
attrs = getattr(func, 'predicates', [])
attrs.append(value)
setattr(func, 'predicates', attrs)
return func
return decorate
@predicate('something')
@predicate('another')
def bar(test):
print 'Test: ', test
print bar.predicates
If the Predicate base class had something like that in .__init__, could it be
used to deterministically build the list of predicates that were being applied
to an action?
I apologize for asking this before examining the code in question, but you
might be able to answer in 3 seconds what might take me a day to find. Also,
brainstorming is fun. :-)
