Greetings,
Sorry for the dubious title :o). I was wandering if there is a standard
(or reliable) python module that implements the following feature:
http://code.activestate.com/recipes/198078/
>>>Recipe 198078: Wrapping method calls (meta-class example)
>>>
>>>A metaclass is used to wrap all (or just some) methods for logging
purposes. The underlying mechanism can be used as well to check pre/post
conditions, attribute access,... The basic point is, that the actual
class must not be changed in any way to achive the desired effect.
I had to adapt the code to some of my needs, but now it's almost
working, by simply defining a metaclass for any of my class, I get the
class methods calls logged with the instance that called the method, the
method name, the call line in the file, the parameter **value** passed
to the method and the returned value.
It just saved me from hours of ipython interactive debugging with the
old print way, and to beauty of it: I don't have to write any
"self._log('Please log me')" line.
As it is so useful, I bet there is a module that is doing this in a more
reliable way that I did. Anyone has heard of it ?
Jean-Michel
