[seed] New project around the kernel
by Nicolas Paez 31 Aug '10

31 Aug '10

Hi, I am working in the RMoD team (INRIA) in a project called /Seed/. One of the tasks of the project is to identify those mandatory classes that should be part of Pharo kernel. Currently, Pharo kernel has some "unhappy dependecies". We are using /Moose + Glamour/ to create a tool (a browser) that help up with this task. The idea is to start by loading in our browser the classes used in the /SpecialObjectsArray/ and then iterate to add dependencies incrementally. This way we will be able to detect smells and "blacklist" methods we don't want to be part of our kernel. During this days we will have a working version of our browser to start the analysis. If you want to take a look, search for Seed on SqueackSource. We will be sharing our findings in the Pharo mailing list. Regards, NicoPaez.

JNIPort
by Cyrille Delaunay 31 Aug '10

31 Aug '10

Hello, If soemone is interested in JNIPort, I just published a small example using it. It is not doing yet what I was expecting :), but it already set up correctly a Pharo 1.1 image to run the example (loading Alien, JNIPort, making a link to the JAVAVM for mac). In this example I try to generate a mse file with infusion, by directly invoking the main method of Java2Mse (instead of invoking OSProcess to execute the script). All seems to work fine (except that the mse file is not generated, I still have to find why). To load it, this should work (for a pharo 1.1 image): Gofer new url: 'www.squeaksource.com/DelaunayTmpStuffs'; package: 'JNIPortExample'; load. There is a class comment and an example in the class side ('cyrilleOwnExample').

Problem with the class category importer?
by Alexandre Bergel 31 Aug '10

31 Aug '10

Hi! I just grabbed the hudson image, and imported Mondrian in it. It is said that Mondrian is composed of 53 packages! It should be about a dozen. When I click on "All model packages", I see many repeated item. I imported Mondrian using the class category importer. A screenshot attached Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

FAMOOSr program is online
by Mircea Lungu 30 Aug '10

30 Aug '10

Hi Moosers! You can now check out the FAMOOSr program online at http://www.moosetechnology.org/events/famoosr2010 As soon as we will have all the final versions of all the papers we will upload them and then let you know. For those of you that won't be able to attend, we advise you to have a look at the papers, and send questions that could fuel the discussions. Even if you will not be there, your name and questions will be heard. On the other hand, if you plan to attend ICSM then consider also attending FAMOOSr. There is no extra registration fee for it. However, we still invite you to go to the ICSM registration page and update the list of events you will attend. Best regards, Mircea & Simon. Organizers. -- Mircea Lungu Researcher Software Composition Group University of Bern http://lungu.org/mircea

Some strange things when export as png
by Laval Jannik 28 Aug '10

28 Aug '10

Hi, I tried to export as png in Mondrian Renderer. The first time, I changed the name in the open popup. The image did not create. The second time, I do not change it, the image was created but, it is strange (see in attachment). Texts are not taken into account. I am not sure it comes from Mondrian itself. I am using the Cog VM. So can anyone try to export and to give feedback ? Thank you. --- Jannik Laval

Re: [Lsehub-staff] Moose installation issue
by Simon Denier 27 Aug '10

27 Aug '10

Hi Nico As you noticed, Moose is not (yet) made to load in a Pharo Core image. The full suite can only be loaded in a Pharo normal image. Now it would be cool to have a special 'Core' configuration which could be loaded into a PharoCore for analysis. I know that Jannik worked on that a bit. Especially since we now have good tools (dsm, blueprints) to take a look into that :) So one dependency which we cant escape is the refactoring browser, because of the Smalltalk importer. BTW, if you plan to use Moose regularly, the best is to subscribe to the mailing list: https://www.iam.unibe.ch/mailman/listinfo/moose-dev On 27 août 2010, at 11:13, Nicolás Paez wrote: > Hi, to workaround this issue, I started the setup again, loading first the RB package and after that Moose, that was enough to prevent the warning and everything went ok. > > > Saludos! > Nico. > blog: nicopaez.wordpress.com > > > On Fri, Aug 27, 2010 at 10:16 AM, Nicolas Paez <nicopaez(a)gmail.com> wrote: > Hi, > > Summary > > > Pharo image: PharoCore-1.1-11411 > VM: Squeak4.1.1.exe > Moose: Loaded using Gofer script available in SqueakSource. > Issue: it fails when trying to general a Smalltalk model > > Details > > This morning I have started by taking a clean PharoCore-1.1 image and launching the installation of Moose using the following command: > > Gofer new > squeaksource: 'Moose'; > package: 'ConfigurationOfMoose'; > load. > (Smalltalk at: #ConfigurationOfMoose) perform: #loadDefault > > After some minutes the installation started I got the following warning message.

Ramblings about FamixInvocation#to, #receiver, #candidates
by Simon Denier 27 Aug '10

27 Aug '10

I am reviewing the code relating to invocations in Famix. I noticed the following. FamixInvocation>>to ^ self receiver Receiver can be a variable or a class, but can also be nil. This seemed a reasonable default at one time, because we do not necessarily now which method we are invoking (but again, we may not have a clear receiver to refer too). However, with respect to other associations, consider: FamixReference: from -> aMethod to -> aClass FamixInheritance: form -> aClass to -> aClass FamixAccess: from -> aMethod to -> aVariable FamixInvocation: from -> aMethod to -> aVariable or a Class ??? (FamixExtension: from -> aPackage to -> aClass (well, this one is just future work :) ) It seems much more intuitive to have: FamixInvocation: from -> aMethod to -> aMethod Now of course, how do we refine that when we may have multiple candidates? What would be a reasonable default? FamixInvocation>>to ^ self candidates ifNotEmpty: [ self candidates any ] FamixInvocation>>to ^ self isASureInvocation ifTrue: [ self candidates first ] (sure invocation does not imply one candidate, so it may still break or be inconsistent) FamixInvocation>>to ^ self candidates size = 1 ifTrue: [ self candidates first ] or: FamixInvocation>>to ^ self candidates Actually, this one has my preference even if slightly different, because with the other choices we make hypothesis which are not clear. FamixInvocation: from -> aMethod to -> a collection of Methods (candidates) -- Simon
