Direct messaging using Slack

by Alexandre Bergel

Hi! In case you are not aware of it, a great number of the Pharo, Moose, and Roassal community members are on Slack. Slack is a very cool messaging platform. If you want to chat with developers and get instantaneous help on a topic, then Slack simply rocks.

Stuck at lookup implementation in "Building ObjVlisp" tutorial

by Edouard Delbar

Hello everyone, I'm new on this mailing list, this is my first mail :-) I'm a student from University of Lille (France). I'm studying this tutorial (I'm using Pharo 4 but it seems not to be a problem):Â http://sdmeta.gforge.inria.fr/Teaching/ObjVLisp/ObjV.pillar.pdf. I'm working with the "ObjVLispSkeleton-StephaneDucasse.1" image loaded from this repository: MCSmalltalkhubRepository owner: 'StephaneDucasse' project: 'ObjVLispSkeleton' user: '' password: '' I'm stuck at "Method Lookup" p11. First, it seems that unit tests "testNilWhenErrorInLookup" and "testRaisesErrorSendWhenErrorInLookup" are not provided, thus I'm not sure that I'm working with the right image (everything was fine until p11 though). Then, the "lookup: selector" is not provided neither. While there is another method named "lookup: selector from: anObjObject", I can't figure out what I'm supposed to do with the second parameter. Here is what I would do: lookup: selector "look for the method named <selector> starting in the receiver.Â The lookup is done for a message sent to <anObjObject>. self is an objClass" ^ self objMethodDict at: selector ifAbsent: [ self objSuperclassId ifNotNil: [ self objSuperclass lookup: selector ] ] Could someone tell me if this implementation is correct? If it's correct, what do you think the second parameter is for?Â Moreover, do you think I'm working with the right image? Thanks. - Edouard
