[Pythonmac-SIG] py-appscript changes to filtering?

[Nicholas Riley]

Hi,

I ran into a bug with py-appscript 0.17.2 (handling apps that had quit
while you still had a reference to them) and updated to the current
trunk.  This fixed this problem but broke some of my other code.  This
code:

        systemEvents = app(id='com.apple.systemEvents')
        frontName = systemEvents.processes[its.frontmost][1].name()

which worked fine with 0.17.2 doesn't work any more.  I get:

  File "/Library/Python/2.3/site-packages/appscript-0.18.0-py2.3-macosx-10.4-ppc.egg/appscript/reference.py", line 457, in __getitem__
    return Reference(self.AS_appdata, self.AS_aemreference.byfilter(
  File "/Library/Python/2.3/site-packages/appscript-0.18.0-py2.3-macosx-10.4-ppc.egg/aem/types/objectspecifiers/specifier.py", line 385, in byfilter
    return ElementsByFilter(self.AEM_want, self, expression)
  File "/Library/Python/2.3/site-packages/appscript-0.18.0-py2.3-macosx-10.4-ppc.egg/aem/types/objectspecifiers/specifier.py", line 425, in __init__
    raise TypeError, 'Not a test specifier: %r' % key
TypeError: Not a test specifier: its.property('pisf')

It works if I use [its.frontmost == True], but that's kind of ugly.
Is this intentional?

Thanks,
