Null Object Pattern
by Sean P. DeNigris Jan. 27, 2014

Jan. 27, 2014

I'm missing something here... I tried implementing: MyNullClass>>#ifNil: nilBlock ifNotNil: notNilBlock nilBlock value. But the notNilBlock is evaluated. I'm assuming it's being inlined. Is that right? How do I workaround? I also tried subclassing UndefinedObject, with the same result. Any ideas? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Null-Object-Pattern-tp4738574.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

browsing comment versions
by Nicolai Hess Jan. 26, 2014

Jan. 26, 2014

Hi, someone interested in browsing older versions of class comments again? The ClassCommentVersionBrowser is gone, but I can add it to the NewVersionBrowser. Just some additional changes to class ChangeSet and NewVersionBrowser are needed. What do you think? nicolai

About doing things late (1 month before release)
by Marcus Denker Jan. 26, 2014

Jan. 26, 2014

Hi, We *really* need to take care. >From what I see, people under-estimate just how much everything has consequencesâ¦ *every*thing that we do will need multiple iterations. Please make sure to take that into account when pushing for something to be added to Pharo3 instead of waiting for Pharo4. Marcus
