[Pharo-project] deleteAllHalos
by stephane ducasse Feb. 9, 2011

Feb. 9, 2011

PasteUpMorph>>abandonAllHalos self flag: #arNote. "Remove the method" ^self deleteAllHalos PasteUpMorph>>deleteAllHalos self halt. self haloMorphs do: [:each | (each target isKindOf: SelectionMorph) ifTrue: [each target delete]]. self hands do: [:each | each removeHalo] it looks to me that this is totally useless :). self haloMorphs always returns #() now even when I completely comment the method deleteAllHalos destroying a morph or a selectionMorph destroy all the halos and the selected morph. Does anybody has experience with that? stef

It was a bit sad. But this was good that we the other young bold and ignorant succeeded to bring the spirit of the Kernel Cleaning Project into young brave souls :) Stef

[Pharo-project] Primitive calls in one package
by Laval Jannik Feb. 9, 2011

Feb. 9, 2011

Hi, What is your opinion about having all primitive calls in one package ? It would be easier to maintain and to find them. Another question: why all existing primitive in VM have not a method in the image ? Cheers, --- Jannik Laval
