Error:invalid utf8 input detected.
by Guillermo Polito June 24, 2010

June 24, 2010

Hi there! We are using Pharo to teach OOP in UTN university, Argentina. Some times students have the error Invalid utf8 input detected when loading an image or doing a file out of a category. I think it happens mostly (or always, i'm not sure) in the OneClicImage, when running on windows. Is it a known issue? Thanks!

Traits versus packages
by Johan Fabry April 30, 2010

April 30, 2010

Hi all, quick question. Preamble: If I have a trait TAMStructuralZoom defined in the package AspectMaps (for example), and I want to apply it to the class FAMIXNamespace, defined in the package Famix-Core (for example), this implies that I need to change the class definition of FAMIXNamespace like this: FAMIXScopingEntity subclass: #FAMIXNamespace uses: TAMStructuralZoom instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Famix-Core' Question: this change is now part of the Famix-Core package, right? Is it possible for this change to be part of the AspectMaps package? I want this for the obvious modularity & source code management advantages. -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

Pharo developers you can subscribe to Pharo-Users too ; )
by Mariano Martinez Peck April 27, 2010

April 27, 2010

Hi everybody. We have two mailing list as you may know: one for pharo developers or people very interested in Pharo and its internal details. This mailing list is pharo-project(a)lists.gforge.inria.fr It is high traffic and there are a lot of people that cannot follow. Then we have the Pharo-User mailing list for those that just want to use Pharo and don't care about their internals. This mailing list has less traffic. This mailing list is pharo-users(a)lists.gforge.inria.fr The problem is that there is people that are subscribed to pharo-project(a)lists.gforge.inria.fr but not to pharo-users. In this last mailing list, usually new comers ask questions. It would be great that all the people that is already subscribed to pharo-project(a)lists.gforge.inria.frand have time to follow that mailing list, to subscribe also to Pharo-Users. Sometimes I am obligued to tell new comers "ask in pharo-project(a)lists.gforge.inria.fr as not all the people is subscribed there" ... and thus, the Pharo-Users becomes useless. Thanks Mariano

Re: [Pharo-users] [Pharo-project] RB AST serialization
by Johan Fabry April 27, 2010

April 27, 2010

(To pharo-users as I am not on pharo-project, and I think neither is Daniel) Yes we have been considering various strategies to get it as compact as possible and considering cputime/memory trade-offs (and making it possible to select compression strategies). But want to get it to work first. These undocumented nodes are the next hurdle: we need some info on RBPragmaNode, RBArrayNode, RBLiteralArrayNode so that Daniel can write the serializer for them.

[ANN] Pharocasts: SandstoneDb (with subtitles !)
by laurent laffont April 26, 2010

April 26, 2010

Hi, I've just uploaded a new screencast which introduces SandstoneDb (and also HelpSystem). http://pharocasts.blogspot.com/2010/04/sandstonedb-simple-activerecord-styl… Note this is my first one with subtitles. There's a link so you can download it and translate it (some people have asked for that). I've used SubtitleEditor (http://home.gna.org/subtitleeditor/) but I don't really like it. Do you know a better software on Linux ? The video is accelerated, it's more dynamic IMHO ( to do this in avidemux, just go in video menu, framerate, and put a higher framerate). <http://pharocasts.blogspot.com/2010/04/sandstonedb-simple-activerecord-styl…> Cheers, Laurent Laffont

Implementing a "prototype" in Pharo
by Miso April 24, 2010

April 24, 2010

Hi, I'm trying to creating a concept similar to "prototype" (like prototype-oriented programming) in Pharo. What I want is an object's methodDictionary to be stored in itself. So when I send a message to an instance, Pharo should look in the instance's dictionary (as opposed to class' dictionary) and call method stored there. Closest thing I managed to do was create an anonymous class (subclass on my custom class) for each instance and return instance of this class, and store the anonymous class in the instance so I can work with it. Is there any other way to do it, without modifying compiler/VM or writing custom compiler? If not, please give some pointers where to look for some information about "core" of Pharo. Thanks Michael -- View this message in context: http://forum.world.st/Implementing-a-prototype-in-Pharo-tp2063374p2063374.h… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

How To Bind To External Libraries in Pharo ?
by Bill Rodgers April 22, 2010

April 22, 2010

Hi Experts, How can I connect to libraries of the type that I would "include" in a C program? Must I re-compile Pharo to include them or is there some other way to do this at run-time? I'm looking at some Gnome libraries (GTK+, Gstreamer) which I would like to use from Pharo. Thanks, Bill

You are the envy of a lot of people, you are being paid to program in something that you really like and enjoy. This is an excellent opportunity so take advantage of it and don't miss it. Please, work hard and deliver something, but never forget to have fun, learn and enjoy. For all the students which were not accepted, don't worry. If your project and proposal is good you will find another opportunity sooner than you expect. For us, this was an excellent opportunity to gather information about really interesting projects and, what's more, to know lots of great students with a passion for Smalltalk. With no doubt, we will keep in touch with all of you and we will eagerly wait your application for next years.

Socket>>accept
by Daniel Birkinshaw April 20, 2010

April 20, 2010

Hi, I'm trying to implement a simple server. What I want the code to do is as follows: * Create a socket and listen on a port * Wait for an incoming connection * When a connection is received, fork a process to deal with it and go back to waiting for connections. I believe the following code should accomplish this (I have omitted the loop and the fork because I want to get it working for a single connection before I start with multiple connections!): server := Socket new. server listenOn: 1234. client := server accept. However when I run this I get Socket(Object)>>primitiveFailed. Examining the stack trace reveals the source to be this method: Socket>>primAcceptFrom:receiveBufferSize:sendBufSize:semaIndex: <primitive: 'primitiveSocketAccept' module: 'SocketPlugin'> ^self primitiveFailed When I take a look in /usr/local/lib/squeak/3.11.3-2135 there are lots of plugins, but no SocketPlugin. Swazoo seems to work fine without it and all of the tests in the NetworkTests package pass.

Dynamic Languages Symposium 2010 October 18, 2010 Co-located with SPLASH (OOPSLA) 2010 In cooperation with ACM SIGPLAN John Ascuaga's Nugget, Reno/Tahoe, Nevada, USA http://www.dynamic-languages-symposium.org/dls-10/ ***** Call for papers ***** The 6th Dynamic Languages Symposium (DLS) at the conference formerly known as OOPSLA is a forum for discussion of dynamic languages, their implementation and application. While mature dynamic languages including Smalltalk, Lisp, Scheme, Self, Prolog, and APL continue to grow and inspire new converts, a new generation of dynamic scripting languages such as Python, Ruby, PHP, Tcl, and JavaScript are successful in a wide range of applications. DLS provides a place for researchers and practitioners to come together and share their knowledge, experience, and ideas for future research and development. DLS 2010 invites high quality papers reporting original research, innovative contributions or experience related to dynamic languages, their implementation and application. Accepted Papers will be published in the ACM Digital Library. Areas of interest include but are not limited to: * Innovative language features and implementation techniques * Development and platform support, tools * Interesting applications * Domain-oriented programming * Very late binding, dynamic composition, and runtime adaptation * Reflection and meta-programming * Software evolution * Language symbiosis and multi-paradigm languages * Dynamic optimization * Hardware support * Experience reports and case studies * Educational approaches and perspectives * Object-oriented, aspect-oriented, and context-oriented programming === Submissions and proceedings === We invite original contributions that neither have been published previously nor are under review by other refereed events or publications. Research papers should describe work that advances the current state of the art. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Accepted papers will be published in the ACM Digital Library. Papers are to be submitted electronically at http://www.easychair.org/conferences?conf=dls2010 in PDF format. Submissions must not exceed 12 pages and need to use the ACM format, templates for which can be found at http://www.acm.org/sigs/pubs/proceed/template.html. === Important dates === Submission of papers: June 1, 2010 (hard deadline) Author notification: July 15, 2010 Final versions due: August 13, 2010 DLS 2010: October 18, 2010 SPLASH/OOPSLA 2010: October 17-21, 2010 === Program chair === William Clinger, Northeastern University, Boston, Massachusetts, USA === Program committee === Robby Findler (Northwestern University) Jeffrey S.

Thanks for all the replies - this is great! >> Got it. In Squeak, this was the mechanism I used to keep objects from different domains separate, > it did not. I meant conceptually and visually - the metaphor (seemed to me) of stepping into another room in a house filled with objects, so I could put all my financial stuff "in my home office" and my reference books "in the study." >> Is there a similar (or better) mechanism for this in Pharo? > Classes? <snip> > I think that you misunderstand projects and also the purpose of classes and instances. > May be you should read some of the books available on my web page like the art of object-oriented programming. Please understand that I am grateful beyond words that people I don't know ( yet :) ) have created, and are maintaining and improving software and reference materials that are transforming my understanding of what's possible with computers. And... I'm good with OOP (and I read every book about OOP and Smalltalk I could get my hands on, including a few of yours, and enjoyed them all). What I'm not grokking is: my understanding of Squeak (which I applied to Pharo) from all of Alan Kay's work is that it's moving closer toward an "application-less" virtual world, where all objects can communicate with all others - instead of Microsoft Money holding my financial data hostage in a proprietary data file, and Apple holding my notes in Mail.app data files, *I* hold all these objects (and the system itself), all written in Smalltalk, so I have complete control over my computer world. Now... what I am curious about (and haven't found a book to address), is what (if any) are the strategies one uses to conceptually make sense of a virtual world of possibly thousands of (normally, mostly) unrelated objects. For example, 9 out of 10 times, I probably don't care that I have journal entries alive in my image when I'm processing receipts, but the one time I want to cross-reference the journal for keywords for certain purchases, I want access to them. And all I've seen in reference books is how to develop "an application" in Squeak/Pharo i.e. code that does one conceptual thing e.g. moves a turtle, rolls a die, creates a laser game - which were all totally great, and also did not give me any insight to this particular question. Maybe it's something really obvious to a long-time Smalltalker that no one's bothered to write down?! Thanks again. Sean

Re: [Pharo-users] Projects
by DeNigris Sean April 6, 2010

April 6, 2010

> Pharo does not support Projects. Got it. In Squeak, this was the mechanism I used to keep objects from different domains separate, but the amazing Smalltalk beauty of it was that the objects could talk and act across the boundary. I was building a utopian digital world without the artificial boundaries of "applications." Is there a similar (or better) mechanism for this in Pharo? For example: If I was using an image for all my personal computing, and I wanted to manage both my personal accounting and my journal; in Squeak, I would create a MyMoney project and a MyJournal project. How would you handle this goal in Pharo? My objective is to have every domain object in my life be able to communicate with every other object, without having one huge, unmanageable pile. Maybe keep the objects in repositories stored in class instance variables in top-level project-like objects? Like have a MyMoney class contain all the money-related objects, and a MyJournal class keep all the journal stuff... Is any of this making sense? Thanks! Sean

Projects/Project Windows
by DeNigris Sean April 6, 2010

April 6, 2010

How do you create Projects in Pharo? In Squeak, you can select "new morphic project" from the world menu. I found out how to do the same thing programmatically: > Project newMorphicOn: nil. The SystemWindow appears - great, no problem; except... I can't figure out how to enter the project. When I click on it (which would enter it in Squeak), nothing happens. I tried a bunch of other stuff, but couldn't make it happen. Thanks! Sean p.s. more generally, is there a way to get removed Squeak world menu options through the GUI? Or do you have to perform the actions programmatically?

by Humble Origins April 3, 2010

April 3, 2010

Hi, I am a newbie and this is my first Smalltalk learning effort. I have downloaded Pharo-1.0-10508-rc2 and it is working fine so far. I just want the system to display all the Shared Tabs. So, when I click Configuration -> show shared tabs menu option I get this error: ======================================================================= MessageNotUnderstood: Project>>currentToggleFlapsSuppressed Project(Object)>>doesNotUnderstand: #currentToggleFlapsSuppressed [] in ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: BlockClosure>>ensure: CursorWithMask(Cursor)>>showWhile: ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: ToggleMenuItemMorph(MenuItemMorph)>>mouseUp: ToggleMenuItemMorph(MenuItemMorph)>>handleMouseUp: MouseButtonEvent>>sentTo: ToggleMenuItemMorph(Morph)>>handleEvent: MorphicEventDispatcher>>dispatchDefault:with: MorphicEventDispatcher>>dispatchEvent:with: ToggleMenuItemMorph(Morph)>>processEvent:using: MorphicEventDispatcher>>dispatchDefault:with: MorphicEventDispatcher>>dispatchEvent:with: MenuMorph(Morph)>>processEvent:using: MenuMorph(Morph)>>processEvent: MenuMorph>>handleFocusEvent: [] in HandMorph>>sendFocusEvent:to:clear: [] in PasteUpMorph>>becomeActiveDuring: BlockClosure>>on:do: ======================================================================= How do I get around this issue to have Pharo display the Shared Tabs? Any help is really appreciated. Thanks.

by Daniel Galdames G. April 3, 2010

April 3, 2010

Hi, i was trying to use FFI plugin on a 64 bits linux, but when I try the test, or FFI-Examples, the vm crash with a segmentation fault. I was able to use FFI with a i686 vm, calling 32 bits libraries. Is there any way to make a 64 bits vm to call 64 bits libraries? or it isn't supported yet? Thanks. Daniel Galdames G.
