Re: [Pharo-project] [NativeBoost] Allow hierarchy of objects in function definition

The InterpreterProxy has #includesBehavior:ThatOf: method, which can be used to test if given class has some specific ancestor in its inheritance chain. The main reason why i did not implemented the code that way is performance. It is not that hard to implement this kind of test (see attached) =========== Btw, we have a problem: - NativeBoost-Core in my 3.0 image shows that last version of it is EstebanLorenzano.116 there is not such package in NB repository. It is in Pharo30 repository.. but when i open it, it shows that it has ancestor NativeBoost-Core-cb.117 Name: NativeBoost-Core-EstebanLorenzano.118 Author: EstebanLorenzano Time: 23 April 2013, 5:52:38.099 pm UUID: d256a011-ce1f-4959-b5ed-37de2c7f3b84 Ancestors: NativeBoost-Core-cb.117 which is not there. Now i cannot merge with code which is in project repository. We should discuss, how we manage updates for NB.. because searching packages located in multiple repositories is tedious and counterproductive. -- Best regards, Igor Stasenko.

It is even more true since the beginning of Pharo 3.0. I see so many things integrated, bugs quickly fixed.

[Pharo-project] Pharo: an AMAZING community

by Sean P. DeNigris

I sometimes take for granted how extraordinary our community is. This morning, it sunk in a bit how magical it truly is... I brought up two issues I was having (not even bugs)... in the middle of the night... on a Saturday... And like the Smalltalk fairy had come and snuck a solution under my pillow while I dreamt, Sven and Benjamin added enhancements which solved my dilemma! Thank you both :) And thank you to everyone that's contributed over these years to make Pharo and its community so special :) ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-an-AMAZING-community-tp4685837.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
