[ann] moose 6.0
by Tudor Girba 15 Aug '16

15 Aug '16

Hello everyone, We are happy to announce version 6.0 of the Moose Suite, the platform for software and data analysis built in Pharo: http://moosetechnology.org/#install Description --- The key highlights are: - It is based on Pharo 5.0 including the latest version of the Glamorous Toolkit. - It includes the SmaCC parsing framework together with parsers and abstract syntax trees for Java, JavaScript and Swift. - Roassal2 comes with several enhancements. - Famix features a new and generic query API engine. - Moose Finder and GTInspector come with more custom presentations and visualizations. - SmaCC comes with a dedicated debugger. - The debuggers for Glamour, PetitParser and Announcements received a new update. - DeepTraverser is an order of magnitude faster. Extra highlights: - Roassal2 is documented in a brand new book: http://agilevisualization.com - jdt2famix is a new open-source importer for Java: https://github.com/girba/jdt2famix Installation --- The Moose Suite 6.0 comes for each platform as a separate bundle: - For Mac: http://moosetechnology.org/res/download/moose_suite_6_0-mac.zip - For Windows: http://moosetechnology.org/res/download/moose_suite_6_0-win.zip - For Linux: http://moosetechnology.org/res/download/moose_suite_6_0-linux.zip The Moose Suite 6.0 can also be loaded in a Pharo 5.0 image either from the Configuration Browser, or by executing the following script: Metacello new smalltalkhubUser: 'Moose' project: 'Moose'; configuration: 'Moose'; version: #stable; load. Enjoy, The Moose team

Re: Problems with mondorian

Hi Tudor, there are two types of problems in the jdt2famix-import.problems file. My project uses Lombok to generate getter, setters and builders and so on (which is quite commmon for java projects). Because of that, some methods can't be found. Consider the following classes: ---------------------------------------- import lombok.Builder; @Builder public class Address { private String postalCode; } ---------------------------------------- import lombok.AccessLevel; import lombok.NoArgsConstructor; @NoArgsConstructor(access = AccessLevel.PRIVATE) public class AddressBuilder extends Address.AddressBuilder { public static AddressBuilder anAddressBuilder() { return new AddressBuilder(); } public Address.AddressBuilder withDefaultValues() { return this.postalCode("23456"); } } ----------------------------------------- I get the following error: unresolved method declaration - withDefaultValues - c:\data\moose\...\AddressBuilder.java - line 12 This error message and its line number (line number 12 is the method header "Address.AddressBuilder withDefaultValues ...") are misleading because at first I thought that the hole method is missing. But it only means that in this method an unresolved method is used. Furthermore I wonder if it were possible to support lombok? The cause of the next problem is that we have multiple smaller applications (e.g. backoffice and frontend) which are separate applications but share a common db. Some of these services have classes with the same class and packagename (e.g. an annotation WebController). This lead to the following error message: unresolved annotation type declaration - WebController - c:\data\moose\....\WebController.java - line 12 I had to start the debugger to find the issue. I found it because AnnotationTypeDeclaration.parent.problems = "Pb(323) The type WebController is already defined" If the package names are different the problems disappears. Then I only get the the lombok errors. As a solution I will create unique base package names for my projecfs (which makes sense anyway). Note that you could the following example to you README of jdt2famix to show how to download the dependencies for gradle projects: task copyDependencies(type: Copy) { from configurations.compile from configurations.testCompile into 'dependencies' } Best regards Meinert -----Original Message----- From: Tudor Girba [mailto:tudor@tudorgirba.com] Sent: Thursday, August 11, 2016 10:41 PM To: Moose-related development Subject: [Moose-dev] Re: Problems with mondorian Hi, Great.

Problems with mondorian
by Meinert Schwartau 12 Aug '16

12 Aug '16

Hi, I want to display the dependencies between my classes. I wonder why the following code does not work, it displays the classes in a circle but not the edges between them. I’m using Moose 6 und Pharo 5 (downloaded yesterday) and evaluated the following code in the moose panel in the evaluator: |view| view := RTMondrian new. view nodes: ArrayedCollection withAllSubclasses. view edges: (ArrayedCollection withAllSubclasses) from: [ :cls | cls yourself ] to: [ :cls | cls referencedClasses ]. view circleLayout. view Then I tried to display the dependencies between my own classes (parsed by jdt2famix) but got an exception. After clicking on All classes in the moose panel I entered the following code in the evaluator: |view allClasses| view := RTMondrian new. allClasses := self allClasses. view nodes: allClasses. view edges: allClasses from: [ :cls | cls yourself ] to: [ :cls | cls providerTypes]. view circleLayout. view If I execute the code above, I get an “MessageNotUnderstood: reveiver of “atScope:” is nil” exception. If I remove the “view edges: allClasses from: [ :cls | cls yourself ] to: [ :cls | cls providerTypes].” statement I don’t get an exception, the RTMondorian view opens, but no classes are displayed as dots in the view. Any suggestions? Best regards Meinert

Thanks. After downloading the current Moose version and using the other method you suggested it works for me :-) Thank you for providing the Java parser.

Moose best practices / workflow
by Meinert Schwartau 11 Aug '16

11 Aug '16

Hi! Currently I have three questions: I want to declare my own methods like isJunitTest, isBookingClass, isMasterdataClass, isGeneratedClass and so on to filter and visualize my classes. As far as I read it these new methods should be added to existing classes. So in my case because they belong to a class to FamixClass. But these extensions should be stored in a separate package. How do you do it? Is there an example in the web how to do this in pharo? How do you save your visualizations and queries? Using the moose panel is nice for prototyping. But in the end I would like to create a menu entry, or a new entry in the moose panel on which somebody can click and sees the result of the query I created. Any suggestions for storing my code in a git repository. It seems not to be so easy like it should be (see http://stackoverflow.com/questions/25722280/pharo-project-on-git) Best regards Meinert

configuration of famix
by Tudor Girba 10 Aug '16

10 Aug '16

Hi, I extended the excellent work of Cyril, and now all Famix related code (including tests) is in ConfigurationOfFamix. We now have 10 failures, but these were failing before as well. Now, the ConfigurationOfMoose contains only 10 packages that are related to the UI and visualization (and one for Moose-Help). I would consider creating a separate configuration for those packages, and leave in the ConfigurationOfMoose only the Moose-Help. Please take a look, and let me know if you see something broken (e.g., missing code). For reference, here is how the configuration looks like now: Cheers, Doru -- www.tudorgirba.com www.feenk.com "It's not what we do that matters most, it's how we do it."

strange errors in jenkins jobs
by Tudor Girba 07 Aug '16

07 Aug '16

Hi, Since yesterday, all Moose-related jobs are failing. These are built on top of Pharo 5.0 stable, downloaded like this: wget --quiet -O - http://get.pharo.org/50+vm | bash We did not change anything in the projects that fail, and locally on Mac, I can load any of the code without problems. The jobs are running Linux. So, I am wondering if anything else has changed in Pharo 5.0. In particular, the error is quite strange. It looks like this: [31mError: MessageNotUnderstood: receiver of "finish" is nil [0mUndefinedObject(Object)>>error: [ :err :rcvr | | errCtx errMorph | errCtx := thisContext. [ errCtx := errCtx sender. "Search the sender chain to find the morph causing the problem" [ errCtx notNil and: [ errCtx receiver isMorph not ] ] whileTrue: [ errCtx := errCtx sender ]. "If we're at the root of the context chain then we have a fatal drawing problem" errCtx ifNil: [ ^ self handleFatalDrawingError: err ]. errMorph := errCtx receiver. ... See more at: https://ci.inria.fr/moose/job/fame/1266/console Any idea of what might be wrong? Cheers, Doru -- www.tudorgirba.com www.feenk.com "We cannot reach the flow of things unless we let go."

RTLabel does not implement trachelShapeClass
by Johan Fabry 04 Aug '16

04 Aug '16

And another one. That's not cool :-/ At some point I get to RTLabel>>trachelShapeForOneLine: which does a self trachelShapeClass but that is not defined there, so it goes to RTShape where it is implemented as self subclassResponsibility. -- Does this mail seem too brief? Sorry for that, I don’t mean to be rude! Please see http://emailcharter.org . Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile
