This isn't perfect (global variables have to be set before hooking the
module) but it sort of works:
--------- callable.py ---------------
"""How to define a callable module"""
import sys, new
class CallableModule(new.module):
def __call__(self, *args, **kw):
self._call_(*args, **kw)
def _call_(*args, **kw):
"""A call method"""
print "Called with %r args, %r kw" % (args, kw)
self = CallableModule(__name__, __doc__)
self.__dict__.update(sys.modules[__name__].__dict__)
sys.modules[__name__] = self
----------------------------------
>>> import callable
>>> callable('test')
Called with ('test',) args, {} kw
>>> callable
<module 'callable' from 'callable.py'>
