[Pythius-developers] setattr and list.append()

[Adrien Di M. <Adr...@lo...>]

Hi all,

I'm pretty new in AOP, and I'm looking for all kind of AOP-related stuff
for Python. I found Pythius, and I'm trying to use the Logger aspect in
a small program.
It seems to work fine, but I had a small problem.
I would like to add some log-events when a list is modified.

Suppose I have :

#####################################
class A:
    __metaclass__ = aop.Metaclass
    _aspect = my_logger()

    def __init__(self):
        self.l = []
    ...
#####################################

What I would like to do is to check when "self.l" is changed
(self.l.append() or self.l.pop() or ...) . I tried
to add a "self.before('setattr', 'l', self.list_changed)" but it didn't
work.

How could I do what I'm trying to do ?

This may be a basic problem, but I'm a newbie with all this stuff.

Cheers,

Adrien.
