Model Transformation and Model querying
by Alexandre Bergel 29 Jun '09

29 Jun '09

Hi! Just to share what I am currently seeing while attending a conference on Model transformation. People seems to enjoy the select and collect operations for sets in OCL. For example, this is what I see on a projected slide: context CD:Class def allSuperclasses: self.parents->union(self.superclasses->collect(c | c.allSuperclasses)->flatten()) Apparently, the fact that you can combine these constructs is innovative... Maybe in the future, we should try to target ICMT and other model-like conference.

Files in Moose
by Alexandre Bergel 29 Jun '09

29 Jun '09

Dear List, Currently, there is no connection between instances of FAMIXFile/ Folder and entities that are supposed to be defined in (e.g., a .java files and a class, a .c file and an instance of CAModule). I extended FAMIXAbstractFile with definedEntities to have: FAMIXNamedEntity subclass: #FAMIXAbstractFile instanceVariableNames: 'belongsTo entities' Then I was unsure whether Fame should to be used. Should 'entities' refers to an ordered collection or a FMMultivalueLink. What will be the opposite then? sourceAnchor could be a good candidate, but I am unsure. For now, I did without Fame.

Inserting MooseEntities in a Dictionary in Pharo
by Alexandre Bergel 26 Jun '09

26 Jun '09

Dear Moosers As you may know, identity hashes attributed by the virtual machine ranges up to 4096. This may be problematic when storing objects in a dictionary. We often have to deal with high number of entities, and using dictionary is out of question for performance reason. One solution (inspired from Lukas) would be to use the ID that each MooseEntity has instead of the hash. I will try to see whether hash can be overriden in MooseEntity to return its ID instead. Will let you know. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Class extensions in PhaMoose
by Simon Denier 09 Jun '09

09 Jun '09

Just to announce that external class extensions are now correctly imported in the last version of Moose. To explain: if you import a package A which made class extensions to classes of a package external to the import (say Kernel), such extensions were not taken into account. Only class extensions made to classes of package A were taken into account before. Also got the count of failing tests down to 2 and of error test down to 1. -- Simon

PhMondrian
by stéphane ducasse 09 Jun '09

09 Jun '09

hi all I would like to know the stability of PhMondrian. Apparently Jannik got problem and had to disable caches. What is your experience with it. In particular I would also like to know whether PackageBlueprint works on sqMoose. Would be nice to rescue this nice visualization. In addition is distribution map (the real version) working on PhMoose or PhMondrian? Stef

Difference between receivingInvocations and incomingInvocations
by Alexandre Bergel 09 Jun '09

09 Jun '09

Dear List, FAMIXNamedEntity has a variables named receivingInvocations. FAMIXBehaviouralEntity, a subclass of FAMIXNamedEntity, has a variable incomingInvocations What is the difference between the two? Leftover of Famix2 ?

Re: Class Extensions
by Mircea Lungu 09 Jun '09

09 Jun '09

Hi Guys, I looked a bit in more detail at the class extensions problem. Here I bring a bit more to the discussion table. I attach a Snaut screenshot of an analysis session of Hapax + Code Foo. (seems attachment is too big for the mailinglist so here's a link: http://www.inf.unisi.ch/phd/lungu/files/ClassExtensionsInMoose.png) The panel on the right is the detail of the 91 invocations abstracted in the high-level dependency between Hapax Development and Visual Works. To the right of every method which is extended in a different package thabn Base VisualWorks you can see that package. What you will see is that althoug most of those dependencies are defined in othe packages than VisualWorks Base they still are abstracted in the relationship between Hapax and VisualWorks base. You will see that there is a dependency between hapax and Number>>pythag: which methoid is defined in Hapax itself. The reason is the following. A method, even when it is an extension (isExtension is True) belongsTo a class. And the class, logically, belongs to the namespace where it was initially defined and is, logically, packaged in the package it was initially defined in. When I compute the high-level depedencies in softwarenaut i aggregate them from methods to classes and from there up along the namespace of package hierarchy. Since the extended methods are placed in their original classes, I end up with dependencies between the wrong packages. The high-level dependencies in softwarenaut are wrong because the model can not express the existence of class extensions. I can see two solutions: - we introduce a FAMIXClassExtension as an explicit entity which is a class which has a reference to the extended class. maybe we can even introduce a new relationship which is Class Extension. - we piggyback the class extensions on top of the classes in a similar way the metaclasses are implemented. In our example, for Collection we would define a Collection class in CodeFoo, SqueakExtensions, EyeSee and ech one of these would only contain the methods that it defines. I am interested if anybody else is interested in this. And I want to hear your opinions. Cheers, Mircea.
