Re: [Pharo-users] OpenGL project

by Dimitris Chloupis

yeap NBOpenGL relied on NativeBoost and our new FFI is UFFI so that means that NBOpenGL does no longer work and there are no plans to make it work at least for now. The problem is that Nativeboost was doing machine code stuff that were difficult to maintain and so it does low level stuff with NBOpenGL. UFFI however is very similar to Nativeboost, so porting OpenGL to it is certainly much easier than rewriting the whole wrapper. Obviously OpenGL being huge wont be a walk in the park , however the good news is that NBOpenGL was automating the process with auto generating wrappers. If you wish you can do the porting to UFFI and Esteban will be willing to answer questions oh how can make it work. Esteban is the man behind UFFI and our full time dev of Pharo.

Re: [Pharo-users] How to access XML tag name?

by Blondeau Vincent

Hi, The qualified name in function startElement: aQualifiedName attributes: aDictionary, will be FILMS and after FILM and after TITRE,...etc... So, you have to tell to your shouldVisit: method to accept TITRE too and get in and after you should implement characters: to get the content on the tag.

How to access XML tag name?

by stepharo

Hi Yesterday I started to hack a smart SAX handler. The idea is that I want to just specify the tags I want to visit and the SAX handler should invoke (generated) visit methods. Like that I can easily get visitors on XML domain. Here is an example of what I did. | h | h := SmartSAXHandler new visitor: (MyFilmVisitor new visitTags: #(FILM ROLE)); on: FileSystem workingDirectory / 'FILMS.XML'. h parseDocument. ^ h SmartSAXHAndler >> startElement: aQualifiedName attributes: aDictionary (visitor shouldVisit: aQualifiedName) ifTrue: [ visitor perform: (visitor createdVisitSelector: aQualifiedName) with: aQualifiedName with: aDictionary ] Object subclass: #GenericTagSAXVisitor instanceVariableNames: 'visitTag visitTags' classVariableNames: '' category: 'SmartXMLHandler' GenericTagSAXVisitor>>visitTags: aCollection "set the tags that will lead to a call to a visitTag:with: method in the visitor" visitTags := aCollection collect: [ :each | each asLowercase ]. self createVisitMethods. and in a subclass the visit* methods automatically generated Now I could not get when I have a <TITRE>Vertigo</TITRE> where I can get the Vertigo information. I redefined several methods of SAXhandler but without success. <?xml version="1.0" encoding="iso-8859-1"?> <FILMS> <FILM annee="1958"> <TITRE>Vertigo</TITRE> <GENRE>Drame</GENRE> <PAYS>USA</PAYS> <MES idref="3"/> <ROLES> <ROLE> <PRENOM>James</PRENOM> <NOM>Stewart</NOM> <INTITULE>John Ferguson</INTITULE> </ROLE> <ROLE> <PRENOM>Kim</PRENOM> <NOM>Novak</NOM> <INTITULE>Madeleine Elster</INTITULE> </ROLE> </ROLES> <RESUME>Scottie Ferguson, ancien inspecteur de police, est sujet au vertige depuis qu'il a vu mourir son collegue. Elster, son ami, le charge de surveiller sa femme, Madeleine, ayant des tendances suicidaires. Amoureux de la jeune femme Scottie ne remarque pas le piege qui se trame autour de lui et dont il va etre la victime... </RESUME> </FILM>

OpenGL project

by Thibault Raffaillac

Hi, I would like to do a bit of OpenGL in Pharo, but it does not seem to work at the moment. Tried NBOpenGL with a spur image (50560): _ fails at installation from configuration browser (need to click again on installing to get all classes) _ demo "GLTTRenderingDemo new openInWorld" fails at NBGLContextDriver with error "No suitable implementation found for initializing OpenGL context for your platform" (running on a Mac) Tried with a pre-spur image (50496): _ same weirdness at installation _ demo fails at NBGLCurveRenderer with "MessageNotUnderstood: receiver of on: is nil" Is there a working demo available out there? I have worked a lot with OpenGL ES 2.0 and could definitely provide work on the topic. Cheers, Thibault

Re: [Pharo-users] OSSubProcess and image startup

by Mariano Martinez Peck

Hi Norbert, I have never seen that issue before. Do you know if it happens only with that image (maybe a condition that happened at image save)? Or can you reproduce it with a fresh image?

How to get GLMSystemWindow from GTPlayground

by Norbert Hartl

I wanted to write a small utility snippet involving GTPlayground. I want to transfer all my playgrounds from one image to another image. Something like (GTPlayground allInstances reject: [ :each | each title = 'Playground' ]) do: [ :each | (each title asFileReference , #pg) writeStream nextPutAll: each entity content string; close ] The snippet depends on the window title. I think I've found a bug because in the menu "Change titleâ¦" does not change the title of GTPlayground but of the GLMSystemWindow it is associated with. I did not find the way to get the GLMSystemWindow from the GTPlayground in order to be able to access the title. thanks, Norbert

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 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
