[Pharo-project] sprint image preparation
by Camillo Bruni May 2, 2013

May 2, 2013

Could we upload a new version of the latest image with all the DateAndTime delays removed? I think that would be nice for the sprint tomorrow. I can do it later this evening, unless some special care is needed for that?

[Pharo-project] NewListModel and AlainTreeModel
by Benjamin May 2, 2013

May 2, 2013

Hello :) I am glad to announce that I have spent some time on Spec, and introduce to new models :) 1) NewListModel This is the spec model for the new implementation of the list. It adds some cool features like a header, a real lazy display implementation, a better mechanism for drag and dropping and few more :) The spec model almost cover everything, and is backward compatible with ListComposableModel :) It means you can switch by just changing the instantiateModels method. Soon I will officially migrate to the NewListModel as default, but right now both exists. 2) AlainTreeModel This is the spec model for MorphTreeMorph (the name is a tribute to Alain Plantec ^^). Every one (should) know that MorphTreeMorph is *a lot* more powerful and flexible that PluggableTreeMorph, so I encourage every one to use it :) Once again, the api is the same, so AlainTreeModel is fully compatible with TreeModel. And once again, I will turn it into the default TreeModel soon, but I give you a bit of time to chase bugs :) If you want to try the new models, I will be glad to collect your feedbacks, to help you as much as I can, and to fix the remaining bugs :) Ben

[Pharo-project] sprint relocation
by Camillo Bruni May 2, 2013

May 2, 2013

I am thinking if it makes sense to relocate the sprint to my place... Internet was down every 10mins today and they have problems with the connection here at the lab since a week. Without network we're pretty much dead for a sprint. We've been watching movies at our place with around 20 people, that works. I have a big table (for 10 people or so) a table in my room and 2 more tables. so we might manage to get 2.

[Pharo-project] How i can retrieve the global by its name?
by Igor Stasenko May 2, 2013

May 2, 2013

Hi, all do not think that i am drunk or vent crazy, asking such silly question, which at best should be asked only by beginner :) I know the answer: Smalltalk at: #SomeName or Smalltalk globals at: #SomeName what stroke me, just now, that both answers is wrong! It should be: #SomeName asGlobal (or suggest more appropriate/precise method name for a symbol) optionally, we could also have one, with handling absent case: #SomeName asGlobalIfAbsent: [] same , but only if present: #SomeName asGlobalIfPresent: [:global | ] Currently, there is 941 references to 'Smalltalk' global in my pharo image. If we introduce this convenience method, it will shrink this number considerably, not saying that code will be more elegant and concise compare: (Smalltalk globals at: #Foo) doSomething and #Foo asGlobal doSomething P.S. What really strikes me is why we don't have such method from very beginning, and instead refer to 'Smalltalk' all over the places. Some things are so deeply indoctrinated in our minds, that we don't even think that it can be different. -- Best regards, Igor Stasenko.

[Pharo-project] Printing TraitCompositions (was Re: How i can retrieve the global by its name?)

(We > always do, and that gives us problems later ) That reminds me: I found a bug when aliasing binary selectors in Traits. Until today Squeak's Associations printed without whitespace around the ->, so in a trait like Object subclass: MyObject uses: TMyTrait @ {#* -> #+} the Browser would print the TraitComposition as "TMyTrait @ {#*->#+}". (This isn't valid Smalltalk: it's the Symbol #*-> followed by garbage.} I'm not sure what the situation is in Pharo (I'm not in a position to check it right now), but it's worth a look. frank > On Thu, May 2, 2013 at 6:33 PM, Chris Cunningham <cunningham.cb(a)gmail.com> > wrote: >> >> On Thu, May 2, 2013 at 9:29 AM, Esteban Lorenzano <estebanlm(a)gmail.com> >> wrote: >>> >>> >>> #bindedClass >>> #bindedClassOn: anEnvironment >>> >>> looks clearer to me. >>> >>> Esteban >> >> maybe: >> #boundClass >> #boundClassOn: anEnvironment >> >
