Referring to the attached graph, what is the best way to approach the following in Roassal. Currently with Mondrian I produce a produce a custom shape using the forms builder in #mondrianShape, which is a method of my ModelRoot class. Referring to the attached graph, as an example this shows the class name "Substation" above the instance "SS1" and has a space for contained items to be displayed within it. >>mondrianShape | builder | builder := MOFormsBuilder new. builder column; center; fill; pref; grow. builder row; center; pref; fill; grow; row; center; pref; fill; grow; row; center; pref; fill; grow. builder x: 1 y: 1 add: ( MORectangleShape new text: #strippedClassName; textAlignment: #left; borderColor: Color white ) . builder x: 1 y: 2 add: ( MORectangleShape new text: #localName; textAlignment: #left ) . builder x: 1 y: 3 add: ( MORectangleShape new ) . builder x: 1 y: 3 add: ( MOChildrenShape new ) . ^builder shape In conjunction with the use of MOChildrenShape above, class ModelRoot also has method #addSubViewTo: which descends through contained classes - for example instance "primary" inside "T1" inside "SS2" inside "Figure 8..." >>addSubViewTo: aMOViewRenderer aMOViewRenderer node: self using: self mondrianShape forIt: [ self children do: [ :child | child addSubViewTo: aMOViewRenderer. ] ] My initial issues in migrating this to Roassal are: 1. Roassal appears to not provide any methods that have "using:" in them. 2. Roassal appears to not support MOFormsBuilder It may be that I am accessing to much internal methods. The code above was the result of evolutionary hacking as I was learning Mondrian. I would be happy to re-architect if someone can advise best practice for Roassal. cheers -ben

migrating to roassal - MOArrowedOrthoVerticalLineShape

by Ben Coman

I am usings the code to produce the attached image. view shape: (MOArrowedOrthoVerticalLineShape new). view edges: inheritance from: #superclass to: #yourself. How do I achieve that with Roassal? And just to document something I got working... previously to hide lines while keeping the layout I was using... view shape: (MOStraightLineShape new color: Color white). view edgesFrom: [ :xx | xx - 1 ]. and now... (view edgesFrom: [ :xx | xx - 1 ] ) do: [ :edge | edge - ROEdge ] . cheers -ben

Quest for Hierarchical Data

by Mircea Filip Lungu

Hello Moosers, As you already know, Dennis is working on the hierarchical graph data structure and its great associated visualization in Pharo :) We have been testing his code on software systems which have an inherently hierarchical structure with low level relationships propagating up along the package structure, but also thought we would try it on a different type of hierarchical data. The two contributions (the HG data structure & the visualization) are after all independent of the domain model. Do you know of any data sources that have the following two properties? 1. There exists a set of relationships between low level, leaf entities 2. The low level, leaf entities can be aggregated along containment relationships One example would be trade relationships existent between companies, can be aggregated to regions, countries, continents... If you are aware of such a data set, we'd offer a beer for the information :) Cheers! M.

MooseChef: to what package do methods belong?

by Nicolas Anquetil

Another MooseChef decision: aPackage queryOutgoingReferences returns all the FamixReferences made from aPackage. this is implemented by taking all methods (self methods) in the package and asking them what reference they make. And we have FAMIXPackage>>methods ^ self localMethods union: self extensionMethods So when asking a package what external references it makes, we get references stemming from methods that extend classes of other packages. We found this while computing a coupling metric for packages. So the solution would be easy to implement, but we are not sure what is the best solution ? - we could change FAMIXPackage>>methods (methods belong to the package that owns their class) - we could change queryOutgoingReferences (references/invocation/accesses stem from the methods in the classes in the package, not from the methods in the package) - or we could change our metric nicolas
