Hi, For an overview on presence/absence of class comments in Moose/Squeak see SqueakSource/PackageExplorer. In order to fix absent class comments I'd need a minimal understanding of the design. A certain book called "object-oriented reengineering patterns" tells me - among other advices - to "skim the documentation". Can you give me a hint what to read on the architecture of MOOSE ? cu Pascal ----- Original Nachricht ---- Von: Stéphane Ducasse <stephane.ducasse(a)univ-savoie.fr> An: Related to the development of Moose and other related tools <moose-dev(a)iam.unibe.ch> Datum: 23.06.2008 11:08 Betreff: [Moose-dev] Re: who can help > Thanks pascal. > Amy be we should create an account for you. > making a list of the class that lack comments and fixing them would be > good. > Sorting also some tests: sometimes we have one class with one test > would be good to. > and help porting.... > Stef > > > On Jun 23, 2008, at 12:12 AM, pascal.vollmer(a)nexgo.de wrote: > > > Hi, > > > > I am prepared to do jobs in the area of: qa, documentation, test, > > statistical methods.

importing from an MSE file does not work
by Richard Wettel 25 Jul '08

25 Jul '08

Hi, I stumble (again) into the same problem. When importing from an MSE file, I get a MNU exception for #accessedByList on the FAMIXNamespace UNKNOWN_NAMESPACE. Is this something you are aware of? I run on top of the latest MooseDevelopment (loaded Moose Config). Thanks, Ricky

MooseModel copy/deepCopy?
by Hani Abdeen 20 Jul '08

20 Jul '08

Hi, How can I have a duplication of a mooseModel (for example the model that represents Mondrian namespace)? exactly like if I imported agin the namespace Mondrian: there is no entity in the duplication that has pointers to entities in the original model. For example, the accesses of a method 'mtd1' into the duplication should not point to classes into the original model. bests, hani

How to only import in a MooseModel the selected packages in the MooseBrowser?
by Romain PEIRS 17 Jul '08

17 Jul '08

Hi, I would know if there is a mean to only import in a MooseModel the selected packages in the MooseBrowser? For example, when I import the bundle Moose in Moose Browser, I would only have in the MooseModel the packages of the bundle. I hope it was clear. Romain

About a model of changes on top of famix
by Stéphane Ducasse 17 Jul '08

17 Jul '08

let us imagine that we would like to see what would happen if we would move a class A from package P1 to P2, without changing the source code and may be been able to undo the change Solution A: We could copy the complete model, modify it. (and keep somewhere an history) Solution B: We could change the model and keep an history of the changes (move A P1 P2). Solution C: I could cache in each model a timestamp similar to what frederic pluquet did and know at which version modification we are. then for a given changes I could get the model by getting entity at the same level or lower. Any thoughts on that. I have the impression that solution B is easier. stef

Re: famix and fame

A word about addTo* methods and slots vs links Fame offers two implementations for properties. If you use links instead of slots, you do not need addTo* methods because the collection returned by a getter is "hot". As far I know the current code generation uses slots, whereas the hand-written code of FM3 uses links. So what is the difference? In short: slots implement the "end" of each property, where as links model the "association" established by the property. For a large project, as eg Moose, I personally suggest to use links instead of slots! Why? Links are less code (not *slot method) Links are less memory (not wrapper objects at 1-end) Links are hot (add and remove on returned collection) Links are more debuggable (no wrapper in the way) @Toon ... this is your call to arms, what are the advantages of slots? :) But first a general issue, why slots or links at all? To automatically update the opposite of an association. A half-only established association is one of the worst bugs in a data-model, it is, to say so, the blink dog of software engineering. Half of the time it works, half of the time not. Hence we decided to make associations a first-level citizen in Fame. Considering Library and Book as an example of a multivalued, ie ( 1 : n ) property, an implementation using slots looks like this Library >> initialize books := FMManySlot new on: self; oppInstVar: #library; youself Library >> books <MSEProperty: #books type: Book opposite: #library> <multivalued> ^books values Library >> books: allBooks books set: allBooks Libary >> booksSlot ^books Library >> addToBooks: aBook aBook libary: self Library >> removeFromBooks: aBook aBook library: nil Book >> initialize library := OneSlot new owner: self; oppInstVar: #books; yourself. Book >> library <MSEProperty: #library type: Library opposite: #books> ^library value Book >> library: newLibrary library set: newLibrary Book >> librarySlot ^library And code to add / remove a book to / from a library like aLibrary addToBooks: newBook aLibrary removeFromBooks: aBook And an implementation using links looks like this Library >> initialize books := FMMultivalueLink on: self opposite: #library Library >> books <MSEProperty: #books type: Book opposite: #library> <multivalued> ^books Library >> books: allBooks books value: allBooks Book >> initialize library := nil Book >> library <MSEProperty: #library type: Library opposite: #books> ^library Book >> library: newLibrary library := FMMultivalueLink on: self update: #books from: self library to newLibrary And code to add / remove a book to / from a library like aLibrary books add: newBook aLibrary books remove: aBook Please note, this is not a violation of the Law of Demeter, since accessing the elements of a container class (ie collection) does not account as "talking" in the sense of the law's "never talk to strangers". As you can see, using links there is no special need for those notorious add / remove methods. cheers, AA > Hi, > > Today, Toon and me worked on Fame and FAMIX in Squeak.
