[Pharo-project] [BUG]NewInspector(Object)>>doesNotUnderstand: #extent:

by roel.wuyts＠gmail.com

I opened a Pharo1.0-10418-BETAdev09.08.2 image, opened a class browser, right-clicked the title bar of the System Browser, and selected Inspect. An inspector opens (successfully), as well as a DNU that NewInsecptor does not understand the message 'extent:'. Browsing around a bit shows that it expects that SystemBrowser expects that it opens a morph and sends the 'etent:' message after opening the inspector (note that it would be better to first resize before to avoid redrawing and flickering). 23 August 2009 11:36:56 am VM: Mac OS - intel - 1058 - Squeak3.8.1 of '28 Aug 2006' [latest update: #6747] Squeak VM 4.2.1b1 Image: Pharo1.0beta [Latest update: #10418] SecurityManager state: Restricted: false FileAccess: true SocketAccess: true Working Dir /Users/rowuyts/Documents/Development/Pharo1 Trusted Dir /foobar/tooBar/forSqueak/bogus Untrusted Dir /Users/rowuyts/Library/Preferences/Squeak/Internet/My Squeak NewInspector(Object)>>doesNotUnderstand: #extent: Receiver: a NewInspector Arguments and temporary variables: aMessage: extent: 300@200 exception: MessageNotUnderstood: NewInspector>>extent: resumeValue: nil Receiver's instance variables: dependents: a DependentsArray(a PluggableSystemWindow(3989) a PluggableTreeMorp...etc... contents: '' selectedObject: a NIObjectNode roots: an OrderedCollection(a NIObjectNode) window: a PluggableSystemWindow(3989) showOnlyCurrentPath: false selectedObjectForPath: nil SystemWindow(Morph)>>inspectInMorphic: Receiver: a SystemWindow(316) Arguments and temporary variables: evt: [270@256 mouseUp 124582 nil] Receiver's instance variables: bounds: 9@44 corner: 713@515 owner: a PasteUpMorph(1622) [world] submorphs: an Array(a WindowEdgeGripMorph(3602) a WindowEdgeGripMorph(3160) a W...etc... fullBounds: 9@44 corner: 714@516 color: (Color r: 0.816 g: 0.812 b: 0.812) extension: a MorphExtension (756) [other: (layoutPolicy -> a ProportionalLayou...etc... borderWidth: 1 borderColor: Color lightGray model: an OBSystemBrowser slotName: nil open: false labelString: 'System Browser' stripes: an Array(a RectangleMorph(3370) a RectangleMorph(3816)) label: a LabelMorph(131)'System Browser' closeBox: a MultistateButtonMorph(1456) collapseBox: a MultistateButtonMorph(1402) activeOnlyOnTop: true paneMorphs: an Array(an OBGroupingMorph(1376) an OBGroupingMorph(60)) paneRects: nil collapsedFrame: nil fullFrame: 9@44 corner: 713@515 isCollapsed: false menuBox: an IconicButton(2697) mustNotClose: false labelWidgetAllowance: 98 updatablePanes: #() allowReframeHandles: true labelArea: an AlignmentMorph(556) expandBox: a MultistateButtonMorph(1563) SystemWindow(Morph)>>inspectAt:event: Receiver: a SystemWindow(316) Arguments and temporary variables: aPoint: 204@63 evt: [270@256 mouseUp 124582 nil] morphs: an Array(an AlignmentMorph(556) a SystemWindow(316)) target: a SystemWindow(316) Receiver's instance variables: bounds: 9@44 corner: 713@515 owner: a PasteUpMorph(1622) [world] submorphs: an Array(a WindowEdgeGripMorph(3602) a WindowEdgeGripMorph(3160) a W...etc... fullBounds: 9@44 corner: 714@516 color: (Color r: 0.816 g: 0.812 b: 0.812) extension: a MorphExtension (756) [other: (layoutPolicy -> a ProportionalLayou...etc... borderWidth: 1 borderColor: Color lightGray model: an OBSystemBrowser slotName: nil open: false labelString: 'System Browser' stripes: an Array(a RectangleMorph(3370) a RectangleMorph(3816)) label: a LabelMorph(131)'System Browser' closeBox: a MultistateButtonMorph(1456) collapseBox: a MultistateButtonMorph(1402) activeOnlyOnTop: true paneMorphs: an Array(an OBGroupingMorph(1376) an OBGroupingMorph(60)) paneRects: nil collapsedFrame: nil fullFrame: 9@44 corner: 713@515 isCollapsed: false menuBox: an IconicButton(2697) mustNotClose: false labelWidgetAllowance: 98 updatablePanes: #() allowReframeHandles: true labelArea: an AlignmentMorph(556) expandBox: a MultistateButtonMorph(1563) [] in ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: Receiver: a ToggleMenuItemMorph(2793)'inspect' Arguments and temporary variables: <<error during printing> Receiver's instance variables: bounds: 206@251 corner: 364@269 owner: a MenuMorph(3977) submorphs: #() fullBounds: nil color: Color black extension: a MorphExtension (832) [other: (layoutProperties -> a LayoutPropert...etc... font: a LogicalFont familyName: DejaVu Sans emphasis: nil pointSize: 10 rea...etc... emphasis: 0 contents: 'inspect' hasFocus: false isEnabled: true subMenu: nil isSelected: false target: a SystemWindow(316) selector: #inspectAt:event: arguments: {204@63} icon: Form(16x16x32) getStateSelector: nil enablementSelector: nil keyText: nil BlockClosure>>ensure: Receiver: [closure] in ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: Arguments and temporary variables: aBlock: [closure] in CursorWithMask(Cursor)>>showWhile: returnValue: nil b: nil Receiver's instance variables: outerContext: ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: startpc: 136 numArgs: 0 CursorWithMask(Cursor)>>showWhile: Receiver: ((CursorWithMask extent: 16@16 depth: 1 fromArray: #( 2r0 2r10000000000000000000000...etc...

[Pharo-project] VMMakerTool >>DoesNotUnderstand ModalFolderSelector

by jean baptiste arnaud

Hi, I would like use VMMaker on Pharo. I resolve all dependency for the VMMaker Package : -FFI,(ScriptLoader loadFFI.) -Speech find in "Unstable Squeak" package from squeaksource -Finally i install VMMaker from squeaksource VMMaker seems work correctly but not this UI. When load the VMMakerTool, i have a error does not understand ModalFolderSelector. -- Arnaud Jean Baptiste

[Pharo-project] Offscreen drawing...

by Lawson English

Is there a way to render into an offscreen buffer where the actual host hardware's address is specified? I realize that at the level of implementing the hooks for the VM, this must be possible, but is it [easily] possible to redirect the memory space that Squeak renders to at runtime, rather than during creation of the VM? I'm trying to understand how one might use the shared memory space of Second LIfe's media plugin to be the drawing region of a regular Squeak Smalltalk workspace/drawing window. Being able to have fully active Smalltalk-on-a-prim in SL would rock, especially if you could have a choice of whether to work directly with the in-world rendering or with the normal Squeak window's rendering. The plugin can live in a separate process and communicate higher level events via sockets and share memory for rendering so its not necessary to have a fully standalone plugin. From the SL side, you could conceivably have a regular Squeak development environment with the added ability to use a specified hardware buffer instead/in addition to the regular Squeak window. Sorta like what seaside sorta does, but without the overhead of rendering via html. Lawson

Re: [Pharo-project] Line end convention in MultiByteFileStream

by Schwab,Wilhelm K

That is an interesting idea. I am not opposed to it, but it would not be my first choice because the additional traces require decompression to view them, and because a potentially memory starved system has to compress them to write them to disk. That said, it it makes people happy enough to adopt the change when concatenation would be refused[*], then I'm all for it. [*] I think I "heard" Stef say "send the code and it's in the core." So, I think the simpler "just keep adding to the file" option will be adopted.

Bill, Perhaps we can address both with a 'technology' used in a lot of Linux distributions: instead of opening a lot of newer files, the (let' call it such way) current file is a regular text file (maybe following the host OS line end conventions [it is a minor concern for me as I intend to develop and test in a dual boot machine]) and the accumulated history is compressed with some of the available methods in the devel image, so we have to take care of only two files, 'normal' (thinking of present) behaviour is almost not changed and the aditional benefits for the situations you mention in addition to be able to see earlier backtraces for all developers. -- Cesar Rabak _______________________________________________ Pharo-project mailing list Pharo-project(a)lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

Re: [Pharo-project] over bloated image workaround

by Carlos Crosetti

Mariano, Ivery value those scripts! My image is small, but anyway I couldn't resist the challenge and tried so far, I got my image shrunk down from 20.7mb to 18.2mb. This is probably a candidate for extending something I may call "the Pharo equivalent to VW Runtime Packager" - I am not so familiar to Pharo to know if such a feature exist.

[Pharo-project] [ANN] Smalltalks 2009 - Third Smalltalk Conference of Argentina

by Andres Valloud

Argentina's third Smalltalk conference, Smalltalks 2009, will be held from November 19th through November 21rd at the Facultad de Ciencias Exactas y Naturales (FCEyN), Universidad de Buenos Aires (UBA). All those connected with Smalltalk, be it faculty, students, researchers, developers or entrepreneurs, are invited to participate, free of cost, as presenters and members of the audience. The organization committee will announce the registration website shortly. The conference's goal is to gather both the Argentine and International Smalltalk community to get connected sharing our work and experience with regards to Smalltalk or related topics. Smalltalks 2009 presentations will be divided between the "Industry and Development" and "Research and Education" categories. In addition, the event will host a Smalltalk programming contest. As in other editions, well known personalities from the international community will attend the conference. The "Research and Education" category is the best match for research and education work done with Smalltalk in universities and public or private entities. The "Industry and Development" category is suitable for presentations related to Smalltalk software developed by companies or individuals, both public and private. A list of suggested presentation topics, not exclusive, is below: * Development tools. * Development with prototypes. * Model driven development. * Agile practices (XP, TDD, etc). * Web application development. * Metamodeling / metaprogramming. * New frameworks or models. * Materials for education. * Embedded systems and robotics. * SOA and web services. * Experience reports, both development and research. * Commercial systems. * Automation and best testing practices. * Interoperability with other technologies. * Best design and architecture practices. Interested presenters should keep in mind the following deadline schedule. 1. You must present a summary of the proposed presentation no later than Monday, October 19th, 2009. The summary must fit on a single page, and must include a description, objective, and category of the work to be shown. The submission procedure will be announced shortly. 2. The conference's program committee will select the event's presentations from the proposals submitted according to the above procedure by Monday, October 26th. The proposals including dynamic examples as opposed to just static presentations will be given priority. 3. The conference schedule will be published in the conference's website on Wednesday, October 28th. 4. The conference's works and presentations will be published in the conference's website after the conference. Those interested in the coding contest can become familiarized with it at the smalltalks-2009-coding-contest Google group: smalltalks-2009-coding-contest(a)googlegroups.com The contest's goal is to have a good time solving a problem in Smalltalk, and win a prize while at it. We are working hard to ensure everyone can participate, and we will show examples and prototypes that can be improved by the participants. For directions to FCEyN, you can go to the computer science department's web site: http://dc.uba.ar Feel free to share this invitation with those who might be interested. If you have any questions, send us an email at fundacion (dot) smalltalk (at) gmail (dot) com See you at the conference! Smalltalks 2009 Organization Committee.
