Hi Alexandre, when I read first this chapter about Roassal and edges I had no good understanding of Pharo. And connecting numbers in the way it is done in the examples confused me. For instance: I did not had in mind, that numbers are objects, and a formula like i // 3 is just a simple way to get a function that relates one object to another one. After attending the Pharo course by FUN, I can understand the examples. But I guess that without understanding Pharo and the way developments are typically done in Pharo, the text is complex to understand not only for me. I had probably needed a text, that explains also Pharo syntax and principles. I have no simple solution to this. I like to do documentation, but I find it much harder than software development. As people are so different and have such a different background. So it took me quite an effort to get my first edges to be drawn (Thanks for helping :-) ). But after I succeeded, it worked reliable. So I was happy :-) To give a more concrete feedback and proposes for improvement of the documentation is on my lists of things to do ...

So sometimes it works, sometimes not for me. Maybe I missed some documentation or good explanation on it :-) Best regards, Rainer -----Original-Nachricht----- Von: "Meinert Schwartau" <m.schwartau(a)gmail.com> An: moose-dev(a)list.inf.unibe.ch Datum: 08/10/16 09:04 Betreff: [Moose-dev] Problems with mondorian Hi,   I want to display the dependencies between my classes. I wonder why the following code does not work, it displays the classes in a circle but not the edges between them. I'm using Moose 6 und Pharo 5 (downloaded yesterday) and evaluated the following code in the moose panel in the evaluator:   |view| view := RTMondrian new. view nodes: ArrayedCollection withAllSubclasses. view edges: (ArrayedCollection withAllSubclasses)  from: [ :cls | cls yourself ]  to: [ :cls | cls referencedClasses ]. view circleLayout. view   Then I tried to display the dependencies between my own classes (parsed by jdt2famix) but got an exception. After clicking on All classes in the moose panel I entered the following code in the evaluator: |view allClasses| view := RTMondrian new. allClasses := self allClasses.  view nodes: allClasses. view edges: allClasses  from: [ :cls | cls yourself ]  to: [ :cls | cls providerTypes]. view circleLayout. view   If I execute the code above, I get an "MessageNotUnderstood: reveiver of "atScope:" is nil" exception. If I remove the "view edges: allClasses  from: [ :cls | cls yourself ]  to: [ :cls | cls providerTypes]." statement I don't get an exception, the RTMondorian view opens, but no classes are displayed as dots in the view.   Any suggestions?   Best regards Meinert _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev
