Hello,

i am not new to Pharo nor to the list but this is the first time i speak here, so : hi =)

��

I started a phd a few month ago (with Alain Plantec) on context oriented programming and dynamic programs adaptation. I am using Pharo for my experiments and i would like to intercept messages sent to an object just before they get to their receiver. To be more specific, when #msg is sent to an object o, i want to be able to intercept it just before it is actually executed with the following objects at my disposal : the receiver (o), the message or selector, the sender. My objective by doing that is to (try to) change the lookup for a given method, and to be able to choose in which class the lookup will start.

��

I have been looking a bit and it does not seem to be a "simple" way to do that in Pharo. Is that even possible and if so, any advice on where i should look ?

��

Thanks,

Steven.
