taking into account pool variable
by Stéphane Ducasse 13 Dec '11

13 Dec '11

Hi apparently the smalltalk importer does not take into account the Pool variables (class variables of a SharedPool subclass and with declared usage in I have to investigate that. Now this is not as simple as for class variables. We have a sharedPool MyPool classVar: Editor LAN.Node poolDictionary: MyPool foo Editor I could either change the class import to check whether the class uses a sharedPool and add their class variables and when I encounter a pool variable usage I have to prefix it with the classPool. Would make sense. I will add an example in the LAN and see if I do not break that many tests. Stef

verveinej and maven
by Tudor Girba 12 Dec '11

12 Dec '11

Hi Nicolas, Do you know if it would be possible to get VerveineJ to work with a pre-existing Maven configuration? I know that Eclipse can (I think through a plugin) recognize the Maven configurations and generate/adapt project properties and dependencies based on this. Would it maybe possible to do the same on the VerveineJ side? Cheers, Doru -- www.tudorgirba.com "The coherence of a trip is given by the clearness of the goal."

reworking the petit browser
by Tudor Girba 12 Dec '11

12 Dec '11

Hi, I just wanted to let you know that I started to rework the PetitParser browser. There are several things that have changed: - it is modular, currently being formed of 3 distinct browsers. To give them a try (I also attached a couple of screenshots): PPAllParsersBrowser open. PPParserBrowser openOn: PPArithmeticParser. PPParserInspector openOn: PPArithmeticParser new. - it only relies on the Glamour mechanisms without state in the implementation code. This was more of a validation that the engine is expressive enough - it has a slightly different layout - the Mondrian map can be used as a navigation, so clicking on a node will focus the browser on that production. - it uses a tree widget for the debugger so we can scale for large debugging traces What is still to do: - install the associated instance variable for each newly created production. - introduce parser renaming refactoring. This would entail triggering both a method and an instance var rename. - add the possibility to remove a production. This would entail removing a method and the corresponding instance var. - make the morph graph view interactive. - add a new grammar class. - integrate tests for each production. This would involve being able to browse tests associated to a production, run, add and remove them. If these would work, we would have a true IDE and for most parts we would not need the Smalltalk editor for building parsers. But, I could use some help on the todos left, especially on the refactorings. Cheers, Doru -- www.tudorgirba.com "Presenting is storytelling."

FAMIXFunction>>packageScope is missing
by Alexandre Bergel 11 Dec '11

11 Dec '11

Hi! We are importing C++ code in Moose and are bumping into problem when using Chef. packageScope is missing on FAMIXFunction. We could have something like: FAMIXFunction>>packageScope ^ self declatedType ifNotNil: [ self declatedType packageScope ] ifNil: [ nil ] Any better idea?

Exception Handling in the Moose Distribution Image
by Mircea Filip Lungu 11 Dec '11

11 Dec '11

Hi guys, This is a bug report I got from one of my students and replicated by myself: In the Moose 4.6 image downloaded from moosetechnology.org, if I execute the following code | c | c := Collection new. c add: 1. the image seems to freeze, although what I would expect is that SubclassResponsibility exception to be raised. This has been observed on Windows and Mac. Do you know about this? Thanks, M. -- Dr. Mircea Lungu Researcher Software Composition Group University of Bern

Fwd: [Pharo-project] Keymapping & OB conflict (was Re: Chasing Browsers)
by Stéphane Ducasse 11 Dec '11

So guys will you maintain petitparser? or Moose will stay in 1.3?

experience with large images?
by jannik.laval 11 Dec '11

11 Dec '11

Hi Alex, With the team at Bordeaux, we are working on an implementation to query histories (the tool is named VPraxis). I implement a importer for Smalltalk. For now, I can load histories for a package, for a metacello configuration, from a repository. A first part is build in Pharo (building snapshots from Monticello), and a second part in build with our java software and build the history file. We can export xml, sql or swipl, which allows us to build prolog queries. Here (http://code.google.com/p/harmony/wiki/VPraxis) is a tutorial for the java VPraxis. For Smalltalk, I am working on it. I generated the current Mondrian history in a swipl format, available here: http://dl.dropbox.com/u/7739334/MondrianHistorySwipl.zip An important point is that we do not into account the multiple branches (it is a current work :) ). So, when there are multiple branches, for now, we check were is the merge and we "ignore the multiple branches". Now, for your question, we create a script: http://dl.dropbox.com/u/7739334/mondrianScript.txt Using swi-prolog (http://www.swi-prolog.org/) , you can call, in this script, the method moreN(L, 10). For the package Mondrian-Layout, it returns: L = [id_MOAbstractGraphLayout, id_MOCircleLayout, id_MOSugiyamaLayout]. Which are the three classes that have changed more that 10 times. For now, I am working on packaging all the things together. But if you have some other requests, do not hesitate to ask me :) Cheers, Jannik On Nov 24, 2011, at 14:05 , Alexandre Bergel wrote: > Having a reification in Moose of 100 versions of Mondrian for example :-) > > Just answering the question 'Which classes and methods of Mondrian have changed more than 10 times since the day Mondrian was born?' cannot be easily done without a lot of memory > > Alexandre > > > On 24 Nov 2011, at 03:27, Francois Stephany wrote: > >> I'm wondering: how big is a dataset > 500MB ?

EyeSee
by Alexandre Bergel 11 Dec '11

11 Dec '11

Hi! I am currently working on a few introductory slides for EyeSee. What ESDiagramTest is for? It is apparently not used and no test methods is defined. I also fixed a couple of methods: - Collection>>openPlot for example was not working. I added an example in ESExample. - #openPlotWith: is cool, but why the two curves are black? Why not having one black and one red? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

keymapping
by Tudor Girba 11 Dec '11

11 Dec '11

Hi Guille, We recently added Keymapping to the Moose distribution (actually part of Glamour), but it seems that it breaks the image in subtle ways: - Ctrl+v and Cmd+v lead to different behaviour - pasting a piece of code leaves the cursor at the beginning of the pasted text Do you happen to have time to look into these?
