[Glamour] default selection in ListPresentation

by Cyrille Delaunay

Hello, Is there a way to set a default selection to a list presentation? so that when I open the browser, the morphic list has already a value selected. I tried that: |tmpBrowser| tmpBrowser := GLMTabulator new. tmpBrowser row: #list. tmpBrowser transmit to: #list; andShow: [:a | a list display: [:input | input]; selection: #a; yourself ]. tmpBrowser openOn: #( b c d v a d f r). but the list still open with nothing selected

[ann] gtspotter: a moldable interface for spotting objects

by Tudor Girba

Hi, Alex Syrel, Andrei Chis and I are happy to announce a new addition to the Glamorous Toolkit: GTSpotter, a novel interface for spotting objects. GTSpotter has two goals: - Provide a uniform yet moldable interface that can work on any object, and - Handle searching through arbitrary levels of object nesting. We think this will have a significant impact on the development workflow in Pharo. Here is a couple of screenshots: [image: Inline image 2] [image: Inline image 1] [image: Inline image 3] A trailer is available here: https://www.youtube.com/watch?v=PhSmjR3NOlU A detailed description is available here: http://www.humane-assessment.com/blog/introducing-gtspotter It works already in Pharo 3.0 and can be played with by following the instructions from: http://gt.moosetechnology.org Please let us know what you think. Enjoy, The Glamorous Team

A quick analyzis of the usage of instance variables in Moose

by Guillaume Larcheveque

Hi Moose users, as you may know, at Synectique we experiment lots of issues about memory usage. That's why i had a look at the number of unused instance variables in one of our system loaded with a big model from one of our main customer. Total instance variables: 26.852.653 Used instance variables: 17.393.938 Empty collections: 5.023.508 Recoverable instance variables: 14.482.223 The recoverable instance variables are those with nil or an empty collection (or MultiValueLink) As you can see, we can save a lot of memory :-) Here is my (dirty) code to get that: countUsedInstanceVariableInForSubInstances: aClass | usedInstNbr instNbr emptyCollNbr | usedInstNbr := 0. instNbr := 0. emptyCollNbr := 0. aClass allSubInstancesDo: [ :anEntity | instNbr := instNbr + anEntity class allInstVarNames size. anEntity class allInstVarNames doWithIndex: [ :e :i | (anEntity instVarAt: i) ifNotNil: [ :content | ([ content isEmpty. emptyCollNbr := emptyCollNbr + 1. false ] on: MessageNotUnderstood do: [ false ]) ifFalse: [ usedInstNbr := usedInstNbr + 1 ] ] ] ]. ^ {('Used instance variables' -> usedInstNbr). ('empty collections' -> emptyCollNbr). ('Recoverable instance variables' -> (instNbr - (usedInstNbr - emptyCollNbr))). ('Total instance variables' -> instNbr)} -- *Guillaume Larcheveque*

Design Challenge: metrics missing value...

by stepharong

Hi dear great OO designers Here is a little challenges for your brainy souls :) In Moose when we compute metrics it may happen than a tool (often external to pharo) does not compute a metrics and when we request it in moose we check and often we return a not so good -1. I'm trying to brainstorm on a solution - first may be the simplest way is to not invoke a metrics when it is not computed. But it means that we should know it and that we should have a registration mechanism. After all this is probably the best solution. - Second we were thinking to use exception but when we have multiple entities missing one metrics.... I have serious doubts. - Second I was thinking about having the following behavior testCollect | uarray collected | uarray := UniformOrderedCollection new. uarray add: 10. uarray add: 20. uarray add: (MissingValue discarding). collected := uarray collect: [ :each | each ]. self assert: collected size equals: 2. testDo | res uarray | uarray := UniformOrderedCollection new. uarray add: 10. uarray add: 20. uarray add: (MissingValue discarding). uarray add: 40. res := 0. uarray do: [ :each | res := res + each ]. self assert: res equals: 70. testCollectDefaulting | uarray collected | uarray := UniformOrderedCollection new. uarray add: 10. uarray add: 20. uarray add: (MissingValue default: 33). collected := uarray collect: [ :each | each ]. self assert: collected size equals: 3. self assert: collected third equals: 33 I basically started to implement do: aBlock "Refer to the comment in Collection|do:." 1 to: self size do: [:index | (self at: index) toDo: aBlock on: self] collect: aBlock "Evaluate aBlock with each of the receiver's elements as the argument. Collect the resulting values into a collection like the receiver. Answer the new collection." | newCollection | newCollection := self species new. self do: [ :each | each toCollect: aBlock on: newCollection ]. ^ newCollection and DiscardingValue >> toCollect: aBlock on: aCollection "discard computation" ^ self Object >> toCollect: aBlock on: aCollection ^ aCollection add: (aBlock value: self) So I imagine that you see the design and I wanted to get your point of view. -- Using Opera a kind of bad mail client but far better than thunderbird

Using Moose outside of source assessment context?

by Udo Schneider

All, I’m dabbling with the idea of using Moose in a totally different questions. However I do have some questions about using it in my context. Would this ML be the right place to ask those questions? CU, Udo

MooseAbstractGroup>>allModelMethods // isStub

by Nicolas Anquetil

any reason why: MooseAbstractGroup>>allModelMethods ... self allMethods reject: [ :each | each parentTypeIsStub ] why not: ... self allMethods reject: [ :each | each isStub ] 1- if a method is a stub, by definition we may not know what its class is 2- even if we know, if the parent class is a stub, then the method itself should be a stub so why this indirection? nicolas -- Nicolas Anquetil -- MCF (HDR) Project-Team RMod

removing the mooseName caching mechanism

by Tudor Girba

Hi, A while ago we put in place a caching mechanism for mooseName. While this has an impact on performance, it makes it a pain to play with the model in any sort of dynamic fashion. It also makes debugging very difficult especially during the development of new importers. Furthermore, it also has issues with assumptions about creating global caches at the model level which are not correct: FAMIXNamedEntities are not uniquely named in the whole model, they are uniquely named within their own type, and for that we already have a cache in the groups. For example, "model allClasses” will give us a group that will also have a cache by the mooseName of classes. This is a heads up that I want to remove this feature. Of course, we can still discuss about it. Cheers, Doru -- www.tudorgirba.com www.feenk.com "What we can governs what we wish."

About parentPackage

by Blondeau Vincent

Hello, Still in the context of Moose re-architecting, we detected that parentSelector is defined at FAMIXNamedEntity level but is only used for Smalltalk model at FamixMethod and FamixClass. As parentSelector is a container, it should not be defined at a too high level. We suggest to move down this property to this both subclasses. Has someone something against it?

Famix entities packaging

by Blondeau Vincent

Hello, In the context of Moose re-architecting, FAMIXCore package should contain only FAMIXCore classes, i.e., only classes common to all languages. We detected some misplaced classes: - FAMIXTypeAlias should belong to the C package like FAMIXModule which is already in. - FAMIXAnnotation*should belong to the Java package. Do you think that these classes have to stay in the core package? Or can we move them? BTW, we also added an opposite to the FAMIXException>> exceptionClass in FAMIXClass.
