[Pharo-project] Issue 3015: When a test is restarted in the debugger, #tearDown and #setUp and not send
by Hernan Wilkinson Aug. 28, 2013

Aug. 28, 2013

Hi, I added a new issue (that I think it could be see as an improvement, not an issue) that is related to debugging a test case written with SUnit. The problem is that when you restart a test in the debugger (either by pressing the restart button or compiling the method again) the changes made by the test to the objects initialized in the #setUp are not rollbacked. This change sends the messages #tearDown and #setUp to the test when restarting it, therefore letting the test in the same state as when it was run in the first place. I uploaded the solution to this issue (or improvement) to pharo inbox under SLICE-Issue-3015-RestartingATestFromTheDebuggerSendsTearDownAndSetUp-HernanWilkinson.2 I hope you like it!

[Pharo-project] Spec DropLists
by Sean P. DeNigris April 16, 2013

April 16, 2013

Issue 6551: [ENH Spec]: Spec-ify DropListModel http://code.google.com/p/pharo/issues/detail?id=6551 Currently: self instantiateModels: #(dropList #DropListModel). item1 := DropListItem named: 'Red morph' do: self redMorphBlock. item2 := DropListItem named: 'Blue morph' do: self blueMorphBlock. item3 := DropListItem named: 'Green morph' do: self greenMorphBlock. dropList items: {item1. item2. item3}. I'd prefer if DropLists were uniform with the rest of Spec, namely: I'd have my domain class MyColor>>description ^ nameOfColor dropList items: {myRedColor. myBlueColor. myGreenColor}; displayBlock: [ :e | e description, ' morph' ]; whenSelectionChanged: [ :e | self showMorphFor: e ]. I'd prefer not to even know that DropListItem exists, and have the model take care of it for me. Something like: DropListModel>>items: aList "Populate the drop list with a list of objects" | items | items := aList collect: [ :e | DropListItem named: e printString do: [ ] ]. listHolder contents: items. Incidentally, #whenSelectionChanged: exists for DropListModels, but is broken. When an item is chosen from the drop list, the announcement received by this block has both new and old contents set to nil: Issue 6550: [BUG Spec]: DropListModel>>whenSelectionChanged: http://code.google.com/p/pharo/issues/detail?id=6550 Cheers, Sean -- View this message in context: http://forum.world.st/Spec-DropLists-tp4643694.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] HMI (was: One more project proposal for GSoC)
by Dennis Schetinin March 30, 2013

March 30, 2013

So, here is the proposal: Name: Khubbatov Rustem Difficulty Level: Intermediate Description A framework for building Human-Machine Interfaces with Pharo back-end providing model, and presentation front-end in Amber. Technical Details A concrete task that should be implemented with this project is a prototype of UI for network management system or SCADA. Server-side (Pharo) will simulate network components and their data, and provide relevant events for client (Amber). The latter will present network items, their state and associated information, and provide UI to control them. An important part of this system is a communication layer between Amber and Pharo. Benefits for the Student The student will gain experience in building client-server applications with advanced UI and providing two-way communication between client and server. Benefits for the Community An ability to create highly interactive web-based applications is a must-have feature for any modern development system. Amber is a bleeding edge in this area in Smalltalk world. A good communication layer between Amber and (for example) Pharo is a very appealing decision for building complex client-server systems.

[Pharo-project] IMPORTANT: Issue 6351: FileReference>>deleteAll follows symlinks in 1.4
by Sean P. DeNigris March 12, 2013

March 12, 2013

This is a fun one to find out about by accident... Hey, what happened to my temporary variable names? Oh, they're decompiled because my image folder was deleted while deleting my home folder because the folder being deleted contained a symlink to it. Thank god for backups... and that it was deleting alphabetically, so mostly rarely-changed config files were deleted (i think/hope)... Pharo1.4 Latest update: #14448 '/path/to/dir' asFileReference deleteAll. * If the link is valid, it follows it and keeps deleting * If not, it claims the link file doesn't exist. http://code.google.com/p/pharo/issues/detail?id=6351 -- View this message in context: http://forum.world.st/IMPORTANT-Issue-6351-FileReference-deleteAll-follows-… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Smalllint for Traits
by aizcorbe Feb. 19, 2013

Feb. 19, 2013

Hi all, as part of a thesis I have been working on, I extended Smalllint to let it check Traits and Traits specific errors. The enviroment objects and the refactoring scope browsers now handles and list classes and traits (before they just handled classes). The new refactoring scope selection is available at "refactoring scope>selection all behaviors" menu option. The smalllint framework have been extended and is available at "refactor>code critics extended". These are some of the changes: smalllint rules can now check traits and traits methods. a new rule presentation schema is available, which lets to spot the place where the error is actually located and also add extra information to the rule result (but is more difficult to define the rules in this way). For extra information about the changes and how can they be used you can refer to: http://dc.uba.ar/inv/tesis/licenciatura/2012/aizcorbe.pdf (refer to chapter 4 if you want to bypass all the conceptual background ) there was also added some rules to check Traits specific errors. The Smalllint for Traits extension is available for pharo 1.3 and is located in: http://www.squeaksource.com/TesisTraitLint the packages are organized as follows: OBLintTraitExtension.1.3 (the smalltalk environment extension to add Traits handling capabilities). TraitLint.1.3 (the Smalllint extension itself and the Traits rules implementation). TraitLintTest.1.3 (the unit tests for the Smalllint extension and the rules implementation, it is not mandatory). I hope you find this useful. cheers -- View this message in context: http://forum.world.st/Smalllint-for-Traits-tp4662559.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Hi Mark, Should have read the man page for open instead of a web page. I had already tried the second version. Still crashes though, with the same error, on 10.6.8 (can try it on newer and older versions too, after finding a working version) Mariano: CogVM-sandard also has the illegal instruction Stephan
