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

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

Fwd: Moose installation issue
by Laval Jannik 27 Aug '10

Hi, Nicolas Paez tried to load Moose in a PharoCore. But SmalltalkImporter depends on RB. I think we should load RB in loadDefault.

Bug with DistrubutionMaps?
by Mariano Martinez Peck 26 Aug '10

26 Aug '10

Hi. I am having a funny bug (I think). For a reason I don't know, some properties (the ones that I think do not have any ocurrences), show a class name instead of the selector. Look and the attached picture. My example is something like DistributionMap class >> anExample ^ (self onContainers: (self listOfCorePackagesNamesWithoutTests collect: [ :each | (PackageInfo named: each) ]) elements: #classes properties: [:element | element propertyInstancesStatesAndAmount ] ) render open. and Class >> propertyInstancesStatesAndAmount propertyInstancesStatesAndAmount | usedInstanceCount unusedInstanceCount | usedInstanceCount := 0. unusedInstanceCount := 0. self isAbstractClass ifTrue: [ (UnusedObjectDiscoverer current primitiveGetUsedBit: self) ifTrue: [ ^ #abstractUsedClass ] ifFalse: [ ^ #abstractNotUsedClass]. ]. self instanceCount = 0 ifTrue: [ ^ #noInstances]. self allInstancesDo: [:inst | (UnusedObjectDiscoverer current primitiveGetUsedBit: inst) ifTrue: [ usedInstanceCount := usedInstanceCount + 1 ] ifFalse: [ unusedInstanceCount := unusedInstanceCount +1 ] ]. (unusedInstanceCount = 0) ifTrue: [ ^ #hasInstancesButNotUsed]. (usedInstanceCount between: 1 and: 10) ifTrue: [^ #usedInstancesBetween1And10]. (usedInstanceCount between: 11 and: 100) ifTrue: [^ #usedInstancesBetween11And100]. (usedInstanceCount between: 101 and: 1000) ifTrue: [^ #usedInstancesBetween101And1000]. (usedInstanceCount between: 1001 and: 10000) ifTrue: [^ #usedInstancesBetween1001And1000]. (usedInstanceCount between: 10001 and: 100000) ifTrue: [^ #usedInstancesBetween10001And100000]. (usedInstanceCount between: 100001 and: 1000000) ifTrue: [^ #usedInstancesBetween100001And1000000]. The last 3 properties: #usedInstancesBetween1001And1000, #usedInstancesBetween10001And100000, #usedInstancesBetween100001And1000000 I guess they have no ocurrences, but, in the reference place in the DM, it shows a class name instead of theor own name, lilke the rest. I tried to track down the issue, but I didn't find anything. Thanks for any help. Mariano

reporting system for pharo
by Cyrille Delaunay 25 Aug '10

25 Aug '10

Hello, In order to provide a reporting system for pharo, I implemented some tools over arki, build some concerns, work on way to save reports. There still work to do, but you can already test it and give me feedback if you want :): Download the package 'MooseComputedConcerns' at: www.squeaksource.com/MooseDemoReport. A message will tell you to resolve depencies by first loading 'System-Benchmarks'. As the concern about benchmarks is not finished you can choose to 'proceed' (the benchmarkConcern will just not been working). Otherwise you can load 'System-Benchmarks' from the same repository (allow 'block argument assignement' in the settings before). Then you will be able, in the moose panel, to right click on a model and open a arki reporter. You can then play a bit with the browser. pay attencion : load the last version of 'Refactoring-core' to be able to use the LintRules-Concern --------------------

Hi Alexander, I updated my image today with the last version of Mondrian (541). I had previously (523). The problem I noticed immediately is a terrible slowdown presenting popup views... They are used a lot in Torch for presenting diffs!! Could you please find the problem? Regards, Veronica
