Hi Thierry, Esteban, i forgot to thnk you for your advices. I tried Metalinks but it cannot intercept messages receptions. I used Ghost, i have been able to do it with virus-proxies and it works well. Le 2016-04-26 15:07, Esteban Lorenzano a écrit :
it is not what MetaLinks are for? I think is easier than Ghost nowadays... but not sure :)
look at
ReflectivityControlTest>>testBeforeSend
seems to be installing an interception "before send", who is what you are asking for.
Esteban
ps: but I might be wrong... Marcus can explain better :)

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 ? The easiest would be to use proxy or ghost objects, which catches all message sends to a proxy of the real object and let you decide what to do with them. A recent announcement on Ghosts for Pharo 5 was done, maybe starting with that could be an idea.

For old timers: wasn't Actalk done that way ?

Thanks,
