Beginners question: How do you work with Moose?
by Meinert Schwartau 12 Jul '16

12 Jul '16

Hi, I'm new to Moose and Pharo and have some problems to get started. So how do you work with the moose panel? For instance, I want to get all packages for all classes of the argouml showcase. I do this like this: 1. Select "All classes" 2. Look in the Meta-Panel which methods are available 3. Enter "self allPackages" in evaluator and execute "Do it and Go" 4. => The result shows 0 The same for allModelPackages. I wonder what's the difference between allPackages and allModelPackages and why both return a result of zero. I would expect to get of all the packages the classes are in. If I do the same for the methods: 1. Select "All classes" 2. Look in the Meta-Panel which methods are available 3. Enter "self allMethods" in evaluator and execute "Do it and Go" 4. => The result shows 23k methods 5. Now I wanted to look at meta panel which methods are available but I don't see any method related except averageNumberOfInvocations and so on. The reason seems to be that the result is of type FAMIXMethodGroup. How to get from the group to the model for the methods so that I can access the parameter list of the methods and so on? So how do you know which methods you can call, do you use the meta panel as well? Why do some methods return an empty result (like allPackages) even though they seem to be valid and should return a result? How to get to the content of a group? Is there a more efficient way to work with moose or is this the way you work with it? How do you investigate these problems if you get some unreasonable return result? Best regards Meinert

Petit Parser Parsing with Spur - Memory Insufficient
by Blondeau Vincent 09 Jul '16

09 Jul '16

Hi, I am currently parsing some git log file with PetitParser. There is 56 log files with 10 more than 1 Mo and a max of 70 Mo. I wrote the parser and all the files parse successfully under a prespur Moose version (Moose #1553). I wanted to migrate to a new Moose image 6.0 (with Spur), the code loads, succeed to parse some small files but I encounter quickly a Memory Insufficient Error... I suspect some bugs either in the Petit Parser parsing process, the string representation, or the memory management. Had someone get the same issue?

VM Crash?
by Jan Kurš 08 Jul '16

08 Jul '16

Hi, I am running the latest moose, with VM from May 4th on Linux and I consistently experience (over a period of several weeks) occasional crashes. My rough observation is that this happens when working with visualization. Do I do something wrong, or are there some issues? The crash dump is attached. Cheers, Jan

semantics of famix reference
by Usman Bhatti 08 Jul '16

08 Jul '16

Hi, While loading one of my existing models, I remarked that the semantics of FAMIXReference have been changed: earlier it was an association between two containers and hence much more permissive. Now it is an association between a method (from side) and a type (to side). Although I agree that the semantics are clearer, sometimes we have the need to represent an association/dependency between two entities. It happens because we are reading from a abstracted source of information (e.g. a description of the model from a modelling tool) that does not have the code-level details. So it will be good to have a more generic dependency. Hence, the question: 1. Does it make sense to add a generic dependency (between two containers? sourced entities?)? 2. Should it be named FAMIXDependency as the word dependency can have different meanings to different people (all dependencies of an entity may be its "computed" dependencies from the dependencies of its children or aggregate of all types of dependencies e.g. accesses, invocations, etc.). So, we need to be careful about the naming. With moose-chef, I would have to tell which entities have this dependency for correct computation of the dependencies but with MooseQuery, we should not have this problem because this information is inferred from the meta-model, right? regards.

Documentation about Fame?
by Alexandre Bergel 08 Jul '16

08 Jul '16

hi Is there at least a bit of documentation about Fame? I am trying to meta-describes some C elements, but it is very difficult. All these are very mysterious: FMNullMultivalueLink, FMMultivalueLink FMMultiMultivalueLink <multivalued> <derived> I feel Fame is very powerful, but very hard to understand.

Famix sourceAnchors
by Stephan Eggermont 07 Jul '16

07 Jul '16

What am I supposed to put as filename in sourceAnchors? I now put the full path there, but that doesn't work and makes things non-portable. In ObjectStudio each method can be in a different file, and they are actually on different drives, e.g. c:\Entwicklung\MSE\FAMIXClass.cls and o:\devtools\sunit\SUnit\SUnit\TestCase.cls. If I remove the drive name, I can no longer find the sources, as there is only one root. If I keep the drive name, I can only use Windows (and it doesn't work because there is no root on Windows) Of course I can work around this by moving all sources into one directory Stephan

Roassal different attachpoints each end of line
by Ben Coman 06 Jul '16

06 Jul '16

How feasible is it to get different attachpoints at each end of an edge? This seems not possible at the moment since RTAbstractLine only has a single 'attachPoint' ivar. Specifically I am wanting from-end==>centre and to-end==>nearestEdge. cheers -ben
