[ANN] OSUnix and OSLinuxUbuntu on new UFFI
by Torsten Bergmann Feb. 27, 2016

Feb. 27, 2016

These two projects (who were based on NativeBoost in Pharo 4) are now updated to new UFFI in Pharo 5 which means they are loadable in recent Pharo 5 image and all tests pass. So if you are working on Linux/Unix you might wan to check them out in latest Pharo 5 by loading them from Catalog browser. A BIG THANKS to Esteban for helping me in the conversion and updating the new Unified FFI (UFFI) according to the issues that were found during the conversion. More is in the pipe ... step by step it goes! Bye T.

Re: [Pharo-dev] [bloc] feature envy -> move method close to data?
by Tudor Girba Feb. 27, 2016

Feb. 27, 2016

Exactly. This is a sensible point. We need to learn a bit more from concrete implementations on top of Bloc before we decide. @Alex: Could you add a flag in the implementation? Doru p.s.

Recursion inside #doesNotUnderstand: method. Why?

Feb. 26, 2016

Hi. Does anybody know why #doesNotUnderstand: is implemented with recursion at the end? doesNotUnderstand: aMessage | exception resumeValue | (exception := MessageNotUnderstood new) message: aMessage; receiver: self. resumeValue := exception signal. * ^exception reachedDefaultHandler* * ifTrue: [aMessage sentTo: self]* ifFalse: [resumeValue]. Best regards, Denis
