Failing tests of MooseModelTest
by Juraj Kubelka 04 Apr '13

04 Apr '13

Hi, I have just found, there are two failing tests in MooseModelTest which have not been discovered by Jenkins. I can reproduce it in the newest Jeninks' build moose-latest-dev-4.8 and also in older too. Do you have the same issue? Methods are #testAsMSEString and #testExport. Problem is in initialization in method: === FMRepositoryVisitor>>run nb := 0. UIManager default displayProgress: 'Writing ', printer stream localName at: Sensor cursorPoint from: 1 to: self roots size during: [ :bar | progBar := bar. self basicRun] === There is "from: 1" and "to: self roots size". "self roots size" returns 1. And then in method Job>>progress ^ (currentValue - min) / (max - min) counts "(max - min)" as "(1 - 1)" = 0 and raises ZeroDivide. Easy fix is to set "from: 0". I would do it, but I hesitate because Jenkins does not introduce this error. Any idea? Cheers, Jura

hasClassScope derived?
by Anne Etien 04 Apr '13

04 Apr '13

Hi, Shouldn't the hasClassScope property of FAMIXMethod be declared as <derived>? It is computed from privateState just as isConstructor or declaredExceptions which are derived. Same question for timeStamp. Thanks in advance. Anne

roassal repository url
by Tudor Girba 04 Apr '13

04 Apr '13

Hi Alex, In the Moose image, the url of Roassal appears as: http://smalltalkhub.com/mc/ObjectProfile/Roassal/main Ideally, it should appear as: http://www.smalltalkhub.com/mc/ObjectProfile/Roassal/main Could you modify it?

Should I port method MOViewRenderer>>getRenderedForm?
by Juraj Kubelka 04 Apr '13

04 Apr '13

Hi, Should I port method MOViewRenderer>>getRenderedForm (and corresponding class MOMorphPainterVisitor)? Out of Mondrian it is used just once in DistributionMapExampleTest>>testSample where it can be easily changed by calling "viewRenderer open delete". Thanks, Jura

cycle detection with moose
by Tudor Girba 03 Apr '13

03 Apr '13

Hi, I wrote up a little blog post describing how we can use the cycle detection that resides silently in the Moose image. Perhaps it can be useful for people: http://www.humane-assessment.com/blog/demystifying--cycle-detection-with-mo… Cheers, Doru -- www.tudorgirba.com "From an abstract enough point of view, any two things are similar."

Call for papers for Dyla'13: 7th Workshop on Dynamic Languages and Applications @ECOOP
by Damien Cassou 03 Apr '13

03 Apr '13

Call for Papers =========================================================== Dyla'13, 7th Workshop on Dynamic Languages and Applications Colocated with ECOOP, ECMFA and ECSA In-cooperation with SIGPLAN and SIGSOFT 1–5 July, Montpellier, France http://rmod.lille.inria.fr/web/pier/Events/Dyla13 !! Important dates - Submission deadline: *April 19th* - Notification: mid-May - Workshop: July 1st - Ecoop early registration: mid-May !! Abstract The advent of Java and C# has been a major breakthrough in the adoption of some important object-oriented language characteristics. This breakthrough turned academic features like interfaces, garbage collection, and meta-programming into technologies generally accepted by industry. Nevertheless, the massive adoption of these languages now also gives rise to a growing awareness of their limitations. A number of reactions from industry testify this: invokedynamic bytecode instruction has been included in latest Java virtual machine release; the dynamic language runtime (DLR) is gaining popularity; C# adopted dynamic as a valid static type. Gartner prognoses further growth (http://blogs.gartner.com/mark_driver/2008/12/10) of dynamic languages. Researchers and practitioners struggle with static type systems, overly complex abstract grammars, simplistic concurrency mechanisms, limited reflection capabilities, and the absence of higher-order language constructs such as delegation, closures and continuations. Dynamic languages such as Ruby, Python, JavaScript and Lua are a step forward in addressing these problems while getting more and more popular. Making these languages mainstream requires practitioners to look back and pick mechanisms up in existing dynamic languages such as Lisp, Scheme, Smalltalk and Self. Practitioners also need to further explore discover new dynamic approaches in the context of new challenging fields such as pervasive computing. The goal of this workshop is to act as a forum where practitioners can discuss new advances in the design, implementation and application of dynamically typed languages that, sometimes radically, diverge from the statically typed class-based mainstream. Another objective is to discuss new as well as older "forgotten" languages and features in this context. Topics of interest include, but are not limited to: - programming language extensions - programming environment extensions - executing environments - static and dynamic analyses - optional type-checking - meta-object protocols - reserve engineering - domain-specific languages/tooling - testing environments - live programming !! Targeted audience The expected audience of this workshop is practitioners and researchers sharing the same interest in dynamically typed languages. Lua, Python, Ruby, Scheme and Smalltalk are gaining a significant popularity both in industry and academia. Nevertheless, each community has the tendency to only look at what it produces. Broadening the scope of each community is the goal of the workshop. To achieve this goal we will form a PC with leading persons from all languages mentioned above, fostering participation from all targeted communities. !! Workshop Format and Submission Information The workshop will have a demo-oriented style. The idea is to allow participants to demonstrate new and interesting features and discuss what they feel is relevant for the dynamic-language community. To participate to the workshop, you can either - submit (before __April 19th 2013__) an article (ACM Tighter Alternate style http://www.acm.org/sigs/publications/proceedings-templates) describing your presentation and/or tool. Articles whose length ranges from 2 to 15 pages will be carefully reviewed by a program committee including but not limited to the organizers. Each accepted paper will be presented for 20 to 30 minutes and be published to the ACM Digital Library (at the option of each author) and the workshop's web site. The submission website is http://www.easychair.org/conferences/?conf=dyla2013. - or give a 10-minute lightning demo of your work. A dedicated session will be allocated for this, provided there is ample time available. A session on pair programming is also planned. People will then get a chance to share their technologies by interacting with other participants. !!

statically typed language
by Nicolas Anquetil 02 Apr '13

02 Apr '13

Famix can be seen as a statically typed language. For example Invocation is an association between two behaviouralEntities (if I recall correctly). The question that bugs me is why (or how) die-hard smalltalkers [ :-) ] ended-up making that choice? nicolas
