Hi Nicolas, Thanks - indeed, iterating over Moose class methods with ... methods select: [:m | m kind = 'constructor'] finds all the constructors pretty easily (parentType to find createe). Then it's the incomingInvocations' sender parentType to find the creators. Cheers! On Fri, Mar 30, 2018 at 3:15 AM, Nicolas Anquetil <nicolas.anquetil(a)inria.fr

Here's a script that I ran on an MSE generated from Java code at https://github.com/bethrobson/Head-First-Design-Patterns to show the <<creates>> relationships in the AbstractFactory example. I had some trouble with RTMondrian and custom composite shapes. I wasn't able to set the colors of the individual elements in the RTCompositeShape that I passed for the nodes. I tried working around it with @RTLabeled, but it prints an "X" where the Character cr is in the string (rather than wrapping). Finally it kind of works with border/fill/textColor: on the RTMondrian shape, but it's not what I expected. ============================ "blocks for readability" findCreators := [ :class | | findConstructors creators | findConstructors := [ :cclass | cclass methods select: [ :m | m kind = 'constructor'] ]. creators := Set new. (findConstructors value: class) do: [ :method | method incomingInvocations do: [ :ii | creators add: ii sender parentType ] ]. creators. ]. newLine := Character cr asString. camelWrap := [ :class | rex := '([a-z])([A-Z])' asRegex. rex copy: class name translatingMatchesUsing: [ :each | (each at:1) asString, newLine, (each at:2) asString ] ]. classes := MooseModel root allModels first allClasses select: [ :c | c mooseName beginsWith: 'headfirst::designpatterns::factory::pizzaaf']. thinArrow := RTDecoratedLine new head: (RTFilledNarrowArrow asHead); attachPoint: (RTBorderAttachPoint new); width: 2. "inheritanceArrow := RTDecoratedLine new head: (RTEmptyNarrowArrow asHead); attachPoint: (RTBorderAttachPoint new); width: 2." myClassShape := RTCompositeShape new add: (RTBox new); add: (RTLabel new text:camelWrap); allOfSameSizeWithPadding. b := RTMondrian new. b shape shape: myClassShape; borderColor: Color black; fillColor: Color paleYellow; textColor: Color black. b nodes: classes. b shape shape: thinArrow; color: Color veryLightGray. b edges moveBehind; connectFromAll: findCreators. "b shape shape: inheritanceArrow; color: Color green; withShorterDistanceAttachPoint. b edges connectToAll: #directSuperclasses." b layout dominanceTree verticalGap: 80; horizontalGap: 5. b build. b view @ RTZoomableView. ^ b ======================================= Adding inheritance to the tree is commented out, but it makes for a mess when laying out both creation and dependency. I had wanted to use RTUMLClassBuilder to show the <<creates>> relations, but finally I gave up since it appears to have inheritance only hard-coded in the edges. I remember someone saying it should/would be re-done with RTEdgeBuilder, so I'm looking forward to that. Another suggestion for RTUMLClassBuilder would be a message forMooseClasses (at least with Java in Moose, maybe forMooseJavaClasses?) message that has these values: forMooseClasses self classname: #name. self instanceVariables: #attributes. self methodsNames: #methods. self superclass: #superclass. self methodselector: #signature. self attributeselector: #name It yields something like this which is nice: Hope this feedback is useful.
