---------- Forwarded message ---------- From: LoÃ¯c Lagadec <loic.lagadec(a)univ-brest.fr> Subject: [Esug-list] CFP IWST'2012 DearÂ colleagues & Friends, We apologize for multiple reception of this announcement. The International Workshop on Smalltalk Technologies, is a European Smalltalk User Group (ESUG) Conference joint event, that focuses on research activities - namely academic creative work undertaken on smalltalk use, and more generally on object technologies. IWST was launched in 2009, in Brest, during the 17th ESUG Conference. The second edition took place in Barcelona, and the third edition was held in 2011 at the heart of historic Edinburgh. Next edition will be in Gent, Begium this summer (28th of august). ESUG gathers groups of professionals and hobbyists who share an interest in the Smalltalk programming languages and related technologies. The goal of the workshop is to create a forum around advances or experience in Smalltalk. IWST contributes to triggering discussions and exchanges of ideas. As always, we make a point to have a very constructive paper review process that aims to provide in-depth comments and suggestions to all of them (no one-liners!) This makes it ideal to disseminate new research directions, and is a good venue for early stage PhD students to receive feedback on their work. In addition, we intent to invite best papers to a journal special issue as we did last year. Looking forward to your submissions, and to meeting you in Gent! Best regards, LoÃ¯c Lagadec & Alain Plantec Co-chairs of IWST International Workshop on Smalltalk Technologies 2012 August 28th, 2012 Gent, Belgium. ESUG 2012 Smalltalk joint event Important dates Submission deadline: June 15, 2012 Notification deadline: July 15, 2012 All accepted papers will be published in ACM DL, and the authors of the best papers will be invited to submit an extended version to a journal special issue (To Be Confirmed). 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. Participants are invited to submit research articles. We will not enforce any length restriction. However we expect papers of two kinds: Short position papers describing emerging ideas. Long research papers with deeper description of experiments and of research results. 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 Links home page: http://www.esug.org/wiki/pier/Conferences/2012/International-Workshop---IWS… submission: http://www.easychair.org/conferences/?conf=iwst2012 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.

yes, you are right, we should improve Morphic, and Gaucho should be released soon! Regarding cleaning up PluggableTextMorph, i think a better solution would be to rewrite it, i've coded NewTextMorph once (a minimal version). Instead of trying to fix an complicated Morph.

Hi Stef, Thanks. The Formule 1 still had a room (others didn't). What's the place to meet on wednesday evening for a beer & talk? I'll arrive 21.00 or so. Stephan

Hi, Hmm. I'm a bit late to make a hotel reservation. Most hotels seem to be booked out. Anyone know an alternative? I'm arriving by train on wednesday. Couch would do. Stephan Eggermont

PluggableTextMorph and friends are a mess, i've tried to clean it up once and found it to be really hard. I will be showing the support for text in Shapes ( the UI framework used by Gaucho), which lays out text using Pango, and renderers it using Athens (with a Cairo backend). Simple and yet powerful, thanks to Pango.

[Pharo-project] SystemNavigationTest>>setUp looks quite strange to me
by StÃ©phane Ducasse May 21, 2012

May 21, 2012

Hi guillermo I saw that you modified setUp super setUp. oldMonticelloAnnouncer := SystemAnnouncer privateAnnouncer. SystemAnnouncer instVarNamed: 'privateAnnouncer' put: nil. navigator := self createSystemNavigationToTest. classFactory := self createClassFactory. Now I would like to understand why? Especially because privateAnnouncer should not be used and touched. SystemAnnouncer privateAnnouncer returns an announcer that should only be used by internal (not tools). BTW the teardown looks wrong to me. Stef

Hi everybody We really want to build a "vitrine" showroom of Pharo and we would you to participate. We want to build a web page with all these successes and show them to the world. :) We would like to get from you a three slides document: slide one: a sexy picture and a teaser / who you are. slide two: what is it how cool is it. slide three: what cool pharo techno you used or developed. If you have two successes then do two set of slides. So can you please send us these three slides. We would like to present them during the Pharo conf and after put them on the web. Stef and marcus.

[Pharo-project] WTF? why this can happen?
by Esteban Lorenzano May 21, 2012

May 21, 2012

Hi, "expanded" is a Set with just one element. executing (somewhere inside pier): expanded removeAll: expanded copy throws NotFound digging a bit, I found that the #scanFor: message answers 5 and real position of object in array is 1 (array size is 5, btw). in: scanFor: anObject "Scan the key array for the first slot containing either a nil (indicating an empty slot) or an element that matches anObject. Answer the index of that slot or raise an error if no slot is found. This method will be overridden in various subclasses that have different interpretations for matching elements." | index start | index := start := anObject hash \\ array size + 1. [ | element | ((element := array at: index) == nil or: [ element enclosedSetElement = anObject ]) ifTrue: [ ^index ]. (index := index \\ array size + 1) = start ] whileFalse. self errorNoFreeSpace this line: index := start := anObject hash \\ array size + 1. is answering 5... so method ends on first ifTrue: but... what the hell???????? any idea? thanks, Esteban

[Pharo-project] Browsing long methods
by Guillermo Polito May 21, 2012

May 21, 2012

Browsing a long method (lets say, of ~270KB of sourcecode) just hangs the image. Interrupting doesn't even give me control over my image again. It does no open a debugger, but info is printed in stdout, so I assume that my UIProcess died, but the event fetcher is still alive... One of the processes that get interrupted prints: SmallIdentityDictionary(SmallDictionary)>>at:ifAbsent: MorphExtension>>valueOfProperty:ifAbsent: MorphExtension>>valueOfProperty: ScrollBar(Morph)>>valueOfProperty: ScrollBar(Morph)>>theme ScrollBar>>normalThumbFillStyle ScrollBar>>adoptGradientColor: ScrollBar>>sliderColor: ScrollBar>>adoptPaneColor: PluggableMultiColumnListMorph(Morph)>>adoptPaneColor: in Block: [:m | m adoptPaneColor: paneColor] So I just changed #adoptPaneColor: in ScrollBar to do nothing, and I am able to interrupt again. So it makes me think here it is where the UIProcess gets killed... Now, for the browser stuff, it seems that TextComposer>>#composeAllLines never finishes. I'm still investigating, but any clue is helpful :). Guille
