Hi Phil,

Ok I missed the details so I've just refreshed my mind.

yes the latest repository is this one: ��http://www.smalltalkhub.com/#!/~CAR/Ghost/
I've just tried in Pharo 3.0 and it works now (yes oups I forgot that it was for Pharo 2.0 ;-)).
Ghost is really small so I've just fixed it

Thanks a lot!
��

Try it: ConfigurationOfGhost load��
Tests are green for me.

I loaded the configuration:

Gofer it
smalltalkhubUser: 'CAR' project: 'Ghost';
package: 'ConfigurationOfGhost';
load.
(#ConfigurationOfGhost asClass project version: #stable) load.

Tests are all green.


No I did not push the config in the right place to have it in the ConfigurationBrowser.

I've put it in the Metarepo for 3.0

You can find infos+examples on how to achieve Method wrapper in Mariano's PhD (p116) using Proxies for Methods.

https://tel.archives-ouvertes.fr/tel-00764991/document��

I didn't had that one, thanks!��

and also look at the test case method named #testSimpleForwardingForMethodUsingBecome

Yes, seen that.

Cheers,

Much appreciated! Ghost is quite nice and useful. Could do with some more class comments as there is none. I'll try to put in some as I use it.

The language you are thinking of is most probably PHANtom:��http://pleiad.cl/phantom But (as author of the language) I think it is overkill to use it for just a memoization cache. Idem for AspectS (I don���t know if it works on Pharo though). Right now, I would use MethodWrappers instead, and when Reflectivity is working use that.

Hi

There is AspectS package at old squeaksource site. I not know is it working in Pharo.
And there was presentation at Esug few years ago about another implementation of aspects in Pharo ( i not remember project name)

That I do have a lot of places like this and do not want these data littering the code.

Aspects would solve this but we do not have that.

Also I need the mechanism to be removable.

So, I read something about MethodWrapper, ghost, slots... Can't one use any of these things to do this memoization cleanly?
