[Pharo-project] In Latest OB I cannot add a class variable
by Mariano Martinez Peck Oct. 3, 2010

Oct. 3, 2010

Hi Lukas. I am using latest OB + RB in PharoDev 1.1 and I have a problem trying to add a class variable. To reprpoduce 1) take any class, for example TestCase. 2) Go to the class side 3) add a class side variable. For example: TestCase class instanceVariableNames: 'history something' 4) The problem is in InteractiveAddClassChange >> definingSuperclass ^ Smalltalk globals at: self superclassName since self superclassName answers nil, because AddClassChange class >> superclassName className isNil ifTrue: [ self fillOutDefinition ]. ^ superclassName className prints -> #'Unknown Class' I attach PharoDebug.log also. Cheers Mariano

[Pharo-project] [ANN] Dynamic Stockholm 2010!
by GÃ¶ran Krampe Oct. 2, 2010

Oct. 2, 2010

Hi fellow Squeakers/Pharooners! On the 19th of october there is a free event in Stockholm that I think will be really good! Unfortunately I can not attend myself. Cincom (Julian Fitzell, Tim Matthews), DevoTeam Quaint (BjÃ¶rn EiderbÃ¤ck) and TPG Objektfabriken (GÃ¶ran Krampe) joined forces and invite you to an evening full of presentations and informal exchange around dynamic languages. Topics will comprise âDynamic languages on mobile platformsâ (Mikael Kindborg, MoSync), âWeb development with Seasideâ (Julian Fitzell, Cincom) as well as a series of mini presentations highlighting cool aspects of each language â the entire agenda will be published shortly. To ensure your seat at this free-of-charge event, please sign up here: http://dynamicstockholm2010.eventbrite.com Of course, there is a distinct Smalltalk-aroma around this event - and we almost named it Smalltalk Stockholm 2010 - but since the content ended up in such an interesting mix of dynamic languages we renamed it. Hope at least some of you might be able to attend! And I guess we will try to tape the presentations. regards, GÃ¶ran
