Re: [Pharo-project] Traits composition question

Is it really necessary that you provides 'self shouldBeImplemented' as method body? > Is there a way to tell to not override the method automatically, if it > provided in base class? No that I know. But this goes against the idea of Traits. A class that uses a trait is rigorously equivalent to having the class implements the methods defined in the trait. As a consequence, if you trait defines a method 'foo self shouldBeImplemented' and your class C uses the trait, then 'C new foo' will execute 'self shouldBeImplemented', independently whether #foo was implemented or not in superclasses of C.

Re: [Pharo-project] Broken "Recover Lost Changes"

by Adrian Lienhard

Hi John, Having looked at your image I think the changes recovery works correctly. The last snapshot was taken at 22nd Oct, 10:06. That is the point in time from which you have lost changes. The image was later restarted on Oct 23, 3:15. After this, more changes were done. I guess at at this point you loaded code or tried to recover code from the changeset. So I assume that the code you lost is between Oct 22 10:06 and Oct 23 3:15. The changes that were done in this period can be recovered as follows: in the Tools menu open "recover lost changes...", then select the top item in the list (Snapshot 22 Oct). What you get is a pretty long list of changes, but you only need a few of them. The first bunch of changes are from the refactoring browser that you had presumably installed at this time. Skip over these changes. Then your changes appear. You can select them up to the item "----STARTUP----an Array(23 October 2009 3:15:57 pm...". Btw, the last thing you did before the image crashed was "someclass become: onotherclass". Apparently the system didn't like that ;) One thing that is suboptimal in the current changes system is that items like preamble: Trait method do it: someMethod ...appear in the changes file. These do-its do not need to be applied when recovering changes. We should probably filter them out from the changes list.

I think a good criterium is whether the functionality is used in Pharo today. Does anybody use rotating morphs? I don't think so.

jannik you ask the right question And this is ugly. Now we could think about possible usecases. If we build a image processing system: we need it but in that case we can copy it.

Re: [Pharo-project] Traits composition question

by Andrew P. Black

>>> >>> For traits, requirements were programmatically inferred instead of >>> using #explicitRequirement. >> In the original traits implementation, inference of requirements was necessarily incomplete. For example, if a method says self add: x or self class new: n we would infer a requirement of add: n the instance side and new: on the class side. However, if the method said self copyEmpty add: x we would not infer a requirement of add: In these cases we included a method definition add: anObject self explicitRequirement to tell the tools that add: was a required method. We used this very rarely, since most of the time the inference of required methods worked very well. Andrew
