I thought about implementing name search in the class DNU, but constants would not benefit from syntax coloring/completion then. Can we import Pool Dictionaries in the Playground? Thibault

Merging refactoring changes
by Peter UhnÃ¡k April 16, 2016

April 16, 2016

Is it possible to merge changesets? For example when I am creating a new class and adding a new instance variable, I would like to see it as one change set, not two. Similarly if I am overriding a method twice, it would be good to see only what actually gets applied. For example ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ " Sandbox removeFromSystem. " (model := RBNamespace new) name: 'ChangeSet'. r1 := RBAddClassRefactoring model: model addClass: #Sandbox superclass: Object subclasses: #() category: #Sandbox. r1 primitiveExecute. r2 := RBAddInstanceVariableRefactoring model: model variable: 'attr' class: #Sandbox. r2 primitiveExecute. r3 := RBAddMethodRefactoring model: model addMethod: 'attr' toClass: #Sandbox inProtocols: 'accessing'. r3 transform. r4 := RBAddMethodRefactoring model: model addMethod: 'attr ^ attr' toClass: #Sandbox inProtocols: 'accessing'. r4 transform. (ChangesBrowser changes: model changes changes) open. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I will get four changes â But the second (top right) could be merged into the first one, and the third one (bottom left) is superfluous. So ideally I would like to have â Is it possible to merge it in such a way? Thanks, Peter

RBRefactoring docs

Hi, is there any documentation for RBRefactoring? Since there are not even class comments the only thing I found is judging from tests. Thanks, Peter

Constants and the Playground
by Thibault Raffaillac April 15, 2016

April 15, 2016

Hi, My work on OpenGL ES is almost done, and I am now trying to play with it in the Playground. However, since constants are stored in a pool dictionary you have to create a class importing it to encapsulate your OpenGL calls, so cannot just write snippets in Playground. This is very annoying for prototyping, so is there a good common design pattern to be able to use constants there ? Cheers, Thibault

Setting the pharo window title from command line
by kmo April 15, 2016

April 15, 2016

I want to change the title of the pharo window to "My Example Application' but the -title command line option does not seem to allow spaces in the title string. I have tried single quotes and double quotes but I always get an error if I try to set the title to more than a singe word. I have been reduced to using hyphens: pharo -title My-Example-Application myimage.image I am using Pharo 4 on Linux. Am I missing something? How do I get spaces in the title string? The problem is made worse by the fact that DisplayScreen>>hostWindowTitle does not work on Linux (in pharo 4 or with 5 and Spur) I also seem to remember that there was also a very useful -geometry command line option once - but this seems to have disappeared. DisplayScreen>>hostWindowSize doesn't work on Linux either. -- View this message in context: http://forum.world.st/Setting-the-pharo-window-title-from-command-line-tp48… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[ANN] SpecGenerator: easy CRUD applications with Spec
by Stephan Eggermont April 14, 2016

April 14, 2016

Sometimes you just want to quickly create an application for data entry, without spending too much time constructing forms and lists. Wouldn't it be great if you could build something while talking to a client, and directly show the results? SpecGenerator helps you with this. It needs the SelectEntity widget that you can get by loading Ancestry from the catalog, and can be found on smalltalkhub in StephanEggermont/SpecGenerator https://vimeo.com/162589115 Stephan

[Bug - Pharo 5.0] Remove a class but not remove for RPackage
by Yann Dubois April 14, 2016

April 14, 2016

Hello, When I delete a class, a window pop to inform me that some methods use this class. So I remove the methods because they are not usefull without my class to removed. But when I close the window, the methods stay on the Browser, so I remove this methods on the Browser. Then, I remove an other class and "BOOM" an error appears, the key which represents my class is not present in the SystemDictionnary (it's normal), but I can find the key in the RPackage metaclasses.

Reminder: CFP - IWST 2016 - International Workshop on Smalltalk Technologies
by jannik laval April 14, 2016

April 14, 2016

[Please accept our apologies if you receive multiple copies of this call] [Please send to interested colleagues / mailing-lists] ************************************************************************************************************ CALL FOR PAPERS IWST16 â International Workshop on Smalltalk Technologies Prague, Czech Republic; August 23th, 2016 http://www.esug.org/wiki/pier/Conferences/2016/International-Workshop-IWST_… ************************************************************************************************************ ------------------- Goals and scopes ------------------- The goals of the workshop is to create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas. The topics of your paper can be on all aspect of Smalltalk, theoretical as well as practical. Participants are invited to submit research articles or industrial papers. This year we want to open two different tracks: one research track and one industrial track with less scientific constraints. We expect papers of three kinds: - Short position papers describing emerging ideas - Long research papers with deeper description of experiments and of research results. - Industrial papers with presentation of real and innovative Smalltalk applications; this kind of paper should enlighten why Smalltalk is really appropriate for your application. *We will not enforce any length restriction.* -------------------- Important Dates -------------------- Submission deadline: *May 15th, 2016* Notification deadline: June 20th, 2016 Camera-ready : July 13th, 2016 Workshop : August 23th, 2016 *All accepted papers will be published in ACM DL (To be confirmed)* *Best papers would be extended in an International Journal* ------------------- Topics ------------------- We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk related topics such as: -Aspect-oriented programming, -Design patterns, -Experience reports, -Frameworks, -Implementation, new dialects or languages implemented in Smalltalk, -Interaction with other languages, -Meta-programming and Meta-modeling, -Tools ------------------- Best Paper Award ------------------- To encourage the submission of high-quality papers, the IWST organizing committee is very proud to announce a Best Paper Award for this edition of IWST. We thank the Lam Research Corporation for its financial contribution which makes it possible for prizes for the three best papers: 1000 USD for first place, 600 USD for second place and 400 USD for third place. The ranking will be decided by the program committee during the review process. The awards will be given during the ESUG conference social event. The Best Paper Award will take place only with a minimum of six submissions. Notice also that to be illegible, a paper must be presented at the workshop by one of the author and that the presenting author must be registered at the ESUG conference. ------------------- Publication ------------------- Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. This site also contains links to useful informations on how to write effective submissions. ------------------- Submission ------------------- All submissions must be sent via easychair: https://easychair.org/conferences/?conf=iwst20160 ------------------- Program chairs ------------------- Anne Etien (UniversitÃ© de Lille 1, France) Jannik Laval (UniversitÃ© Lyon 2 LumiÃ¨re, France) -- ~~Jannik Laval~~ Enseignant-chercheur Responsable PÃ©dagogique Licence Coordonnateur de Projet en SystÃ¨me d'Information IUT LumiÃ¨re, UniversitÃ© Lyon LumiÃ¨re laboratoire DISP http://www.jannik-laval.eu http://www.phratch.com http://www.approchealpes.info
