[Pharo-project] Building the iOS VM - Help
by phil＠highoctane.be March 26, 2012

March 26, 2012

I am trying to build the VM for iOS. Got the sources from the ci jenkins server (the ones that built last month, as the current one is red). /platforms has something looking like it. (iOS) But Cog is x86 and iOS is ARM7. So, I guess that I have to build a StackVM for it to work. But there is nothing about iOS in the instructions (Part1, Part2, ...) The MacOSX VM is documented but not the iOS version. As maintenance was taken over from John, how do we build from here? (I also tried from a copy out of squeak-svn to no avail). My setup: OSX Lion, latest XCode upgraded from Snow Leopard, so I do have GCC on it as well (as LLVM doesn't work). Target devices: iPad 2 3G, iPad 2 Wifi, iPhone 3GS (All with iOS 5.1). My wife is a math teacher and my point with all this is to have a working VM running Dr Geo II. I am currently having fun with Arduino and would like to bridge it with the iPad through the web (using an Ethernet Shield on the Arduino) - the whole chain running Pharo inside self build VMs. The ultimate point is to run a summer camp with kids if I can put everything together by then.

[Pharo-project] XMLParser tiny bug
by Bernat Romagosa March 26, 2012

March 26, 2012

Hi! I've found a little bug in XMLParser and fixed it, but I haven't found any issue tracker for the project, so I don't know where should I submit it. The bug occurs when the parsed page has the xml:lang property set to empty, in which case (anAttributeDictionary at: 'xml:lang') fails. So here's what I did: SAXHandler >> handleStartTag: anElementName attributes: anAttributeDictionary namespaces: aNamespaceDictionary | prefix localName namespaceUri | self elementNester startedElement: anElementName. (anAttributeDictionary includesKey: 'xml:lang') ifTrue: [ self languageEnvironment: ((anAttributeDictionary at: 'xml:lang') ifEmpty: [ Latin1Environment defaultEncodingName ]) ]. " â here " anElementName splitQualifiedNameInto: [ :prefixPart :localPart | prefix := prefixPart. localName := localPart. namespaceUri := '' ]. self usesNamespaces ifTrue: [ self scopeAllocator enterScope. self declareNamespaces: aNamespaceDictionary. namespaceUri := self scopeAllocator resolvePrefix: prefix. self validateStartTag: anElementName prefix: prefix attributes: anAttributeDictionary ]. self saxHandler startElement: anElementName prefix: prefix uri: namespaceUri localName: localName attributes: anAttributeDictionary Cheers! -- View this message in context: http://forum.world.st/XMLParser-tiny-bug-tp4506051p4506051.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] CogVM speed
by Pavel Krivanek March 26, 2012

March 26, 2012

Hi, I tried a few benchmarks from Computer Language Benchmark Game (http://shootout.alioth.debian.org/u32/which-programming-languages-are-faste…) on CogVM to compare it with VisualWorks and with the rest of the world. Of course this benchmarks are not ideal (like all benchmarks) but the result is that CogVM is in average 1.8 times slower than VisualWorks 7.8 NC. For the most successful benchmark (binary-trees) it was 13.5 times slower than C (gcc) but in general we may except CogVM to be 20-30 times slower than C for this kind of tasks. Thank you for the great work! Cheers, -- Pavel

[Pharo-project] File browser with a grid widget
by Alexis Parseghian March 26, 2012

March 26, 2012

I've always found the file browser's flat list over filenames a bit missing, and started experimenting with a grid view. The current version offers 3 columns : filename, size and modification timestamp. Sorting can be on any of them (filename by default). http://code.google.com/p/pharo/issues/detail?id=5549

[Pharo-project] IWST'2012 CFP - International Workshop on Smalltalk Technologies
by Alain Plantec March 26, 2012

March 26, 2012

Apologies for multiple receptions. ------------------------------------------------------------------------ IWST @ ESUG 2012 International Workshop on Smalltalk Technologies Pending ACM In-Cooperation August 28th, 2012 Gent, Belgium http://www.esug.org/wiki/pier/Conferences/2012/International-Workshop---IWS… ------------------------------------------------------------------------ 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 SCOPE 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 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.

[Pharo-project] GSoC proposal: Naked Objects using Magritte
by Stephan Eggermont March 26, 2012

March 26, 2012

After a discussion with Esteban, Nick challenged me to submit a proposal. An alternative would be to start from Glamour instead of from Magritte 3. Proposal: Extend Magritte 3 to create Naked Objects style interfaces Level: Intermediate Possible mentor: Stephan Eggermont Possible second mentor: Esteban Lorenzano Description "What if you never had to write a user interface again? What if you could simply expose your business objects directly to the end user? How would this affect your productivity? The way you work? The flexibility of your applications? Is this even possible? Sometimes, yes. This describes a style of application development, Naked Objects, where you write just the business objects, and a framework lets your users interact directly with these objects." (Dave Thomas) Technical Details Using Magritte we can already build (web/glamour)components representing attributes of domain objects. What should we add to enable a NO UI? - (better descriptions of) relationships between domain objects; - descriptions of actions, with and without parameters; - build a canvas where multiple domain objects can be shown; - make the domain objects identifiable with an icon and title; - add drag-and drop to initiate actions and manage relationships; - add buttons/drop down menus for actions; (and a few other things, of which I'll think when these are finished :) Benefits to the student Learn to use and extend a high quality framework. Learn and practice interaction design. Learn about hexagonal architecture. Benefits to the community The Naked Objects UI enables a very short feedback loop when prototyping a domain model. It provides a showcase for the superiority of smalltalk as a rapid development environment. It allows scaling down the engineering effort needed to create custom solutions. It fits very well with exploratory modeling. In a mixed UI style it allows focusing effort on only the critical parts of the UI.
