Re: [Pharo-project] can someone explain me this method?

Yeah, but sometimes a clever algorithm comes from a book, so to speak. Giving the variables long names, or the constants names, would not make that much difference, it would still be pretty hard to understand.

[Pharo-project] Keymapping - Class vs. Instance Targets

by Sean P. DeNigris

I've run into a lot of trouble implementing the vim bindings because morph instances don't make local copies of the class's maps, so there's no way to override class defaults in an instance. For example, for a particular instance, I can't detach a category that is attached to the class without detaching it from all instances, which I think will not work anyway because existing instances don't pick up those changes.

Dario Trussardi wrote > > Now the conflict is detected only if the method in the image belongs at > the same method category of the relative method in the package. > Hi Dario, There are two different things shown by the merge tool, changes and conflicts. Conflicts are when something [1] which is changed by the-package-you're-trying-to-merge [2] has also been changed in the image, after [2] was saved. The version history of [1] has branched, and you have to choose which branch to follow. IIUC, what you're describing is that a method's category has changed between the image [2]. This may or may not be a conflict, but should appear in the changes list on the left side of the merge tool. If you right-click on an item there, you will see options to cherry-pick what gets loaded.
