Re: [Pharo-project] Customizing the Caret of a PluggableTextMorph
by Fernando Olivero July 20, 2012

July 20, 2012

Hi Sean, you can take a look at Athens-PangoCairo (in squeaksource). Using NativeBoost, i'm using the Pango layout library [1], and the Pango-Cairo binding [2], to avoid laying out text using the outdated (and messy) stuff in the image. Check out the classes: ParagraphDescription & AthensPangoCairoParagraph. I'm using them as the basis for the TextShape,LabelShape, and EditableTextShape in Shapes / Gaucho ( using TextEditor, SingleLineEditor ). Maybe somebody can do the same for Morphic? use Pango to layout the text, and code a new TextMorph on top of it?

[Pharo-project] Spec Enhancement Request
by Goubier Thierry July 20, 2012

July 20, 2012

Hi, could Spec gives access to drag and drop on morphs ? I'm trying to get TreeModel to do things by drag and drop, and I haven't found another way than subclassing it.

Hi! There is some work being done on inferring type (http://concretetypeinference.blogspot.com) What is the theoretical background of this work? What is the algorithm used to infer the types?

[Pharo-project] Pharo 1.4 "Summer" released!
by Esteban Lorenzano July 19, 2012

July 19, 2012

We are proud to announce the summer release of Pharo 1.4! You can find information about Pharo at: http://www.pharo-project.org About this release. We integrated 30 fixes (the rounded number is completely casual) and integrated some tools that users feedback showed as necessary, specially the inclusion of OmniBrowser as part of the core for 1.4. As a result of all this changes and fixes, the stability of this version is a lot better and we are really happy with it. Structural changes to the image: - Backport configurations browser from 2.0. This will easy the loading of packages for everybody, specially newcomers. - Integrated ProfStef. Again, useful for newcomers. - Integrated Spotlight. Easy to find classes and methods. - Integrated OmniBrowser. Nautilus will wait to 2.0 to be core, but it is still loadable. - Integrated Keymapping. This is in fact a sub-product of the inclusion of Spotlight, but the framework is powerful and it deserves its inclusion too :) - Updated Zinc to latest version. Complete list of bugs fixed: - 5665: bug on new ecompletion/ocompletion, http://code.google.com/p/pharo/issues/detail?id=5665 - 5773: Have access to the original event in PLuggableButtonMorph, http://code.google.com/p/pharo/issues/detail?id=5773 - 5584: File Browser not recognizing cs and st if filename has more than one point, http://code.google.com/p/pharo/issues/detail?id=5584 - 5667: Renaming a file just deletes it due to missing #fileNameFromFormattedItem:, http://code.google.com/p/pharo/issues/detail?id=5667 - 5445: Broken command-line arguments in 1.4, http://code.google.com/p/pharo/issues/detail?id=5445 - 5679: Removing a trait does not remove trait methods from class, http://code.google.com/p/pharo/issues/detail?id=5679 - 5722: Be able to remove traits from class definition, http://code.google.com/p/pharo/issues/detail?id=5722 - 5858: DateAndTime >>#hash, http://code.google.com/p/pharo/issues/detail?id=5858 - 5833: More robust allSuperclassesIncluding:, http://code.google.com/p/pharo/issues/detail?id=5833 - 5966: DropListMorph do not pop the list when the text field is clicked, http://code.google.com/p/pharo/issues/detail?id=5966 - 5627: "MessageNotUnderstood: receiver of "displayWorld" is nil" on clicking the red Menu-Halo., http://code.google.com/p/pharo/issues/detail?id=5627 - 5742: BallonMorph shows flyover help using an extra line, http://code.google.com/p/pharo/issues/detail?id=5742 - 6150: During snapshot: Send cr after Transcript message for 1.4, http://code.google.com/p/pharo/issues/detail?id=6150 - 6147: Code completion in all tools for 1.4, http://code.google.com/p/pharo/issues/detail?id=6147 - 6189: [BUG]: Port to Pharo 1.4 - stdin hangs until EOF, http://code.google.com/p/pharo/issues/detail?id=6189 - 6143: MIME decoding and Unicode not working, http://code.google.com/p/pharo/issues/detail?id=6143 - 6188: [BUG]: (1.4) Put back the correct order in #asert:equals:, http://code.google.com/p/pharo/issues/detail?id=6188 - 6187: [Bug]: (1.4) Mouse down events are being processed twice, http://code.google.com/p/pharo/issues/detail?id=6187 - 6117: SimplifiedChineseEnvironment should implement leadingChar, http://code.google.com/p/pharo/issues/detail?id=6117 - 6082: Missed translated selector for the dialog title in the ColorChooserMorph, http://code.google.com/p/pharo/issues/detail?id=6082 - 6231: FileList revert, http://code.google.com/p/pharo/issues/detail?id=6231 - 6303: [BUG]: Completion DNU in Inspector/Object Explorer for 1.4, http://code.google.com/p/pharo/issues/detail?id=6303 - 6305: StartupPreferences "run once" broken, http://code.google.com/p/pharo/issues/detail?id=6305 - 6324: For Pharo 1.4 disable StartupPreferences only for Windows, http://code.google.com/p/pharo/issues/detail?id=6324 - 6313: failing test: MorphicTests.Event.EventHandlerTest.testKeyStrokeFromMorph, http://code.google.com/p/pharo/issues/detail?id=6313 - 6352: StartupPreferences loads non-st files in 1.4, http://code.google.com/p/pharo/issues/detail?id=6352, , - 6373: Add #version to OSPlatform, http://code.google.com/p/pharo/issues/detail?id=6373 - 6366: [Bug]: In 1.4, Finder UI DNU guessTypeByName:, http://code.google.com/p/pharo/issues/detail?id=6366 - 6343: move Windows on screen should take in account the task bar, http://code.google.com/p/pharo/issues/detail?id=6343 - 6386: [BUG]: [1.4]: New ProcessSpecificVariables & Running Processes, http://code.google.com/p/pharo/issues/detail?id=6386 Not bad, isn't?

[Pharo-project] [ANN] The Jejak Trace framework
by Goubier Thierry July 19, 2012

July 19, 2012

I announce the first availability of the Jejak trace framework at http://ss3.gemstone.com/ss/Jejak.html During the VALMADEO project (a PRIR/RÃ©gion Bretagne funded project directed by C. Dezan, <dezan(a)univ-brest.fr>), we needed a tool to study in detail how some algorithms (error correcting codes) could work without errors, but with degraded performance. Execution and compilation would report no errors, but the performance of the error correcting coding and decoding would be several dB below the target. The error correcting code was looping hundreds of times over each block of data, making step by step debugging unusable. Profiling, message tallies were too coarse to tell us anything. We needed a different tool. The answer was this trace tool : a framework for injecting probes into methods, and record their execution. It can record an execution to the smallest detail (all calls, all values, all assignments), that over a long sequence (hundreds or thousands of calls), and let one navigate freely through the recorded trace along with the traced source code. It is capable of tracing system, startup or display methods, without interruption or blocking the overall image, allowing for very fine non-intrusive system analysis. It has been used for debugging turbo codes implementations, algorithm understanding on turbo codes, and memory behaviour analysis for embedded systems design space exploration. It requires The Opal compiler and is integrated with OmniBrowser, and is tested in a Pharo 1.4 image. Instructions for loading are : Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOmniBrowser'; load. (ConfigurationOfOmniBrowser project version: #stable) load: #( 'Dev' 'Dev Tests'). Gofer new url: 'http://smalltalkhub.com/mc/MarcusDenker/Opal/main'; package:'ConfigurationOfOpalCompiler'; load. (Smalltalk at: #ConfigurationOfOpalCompiler) load. Gofer new repository: 'http://ss3.gemstone.com/ss/Jejak'; load There is a lot left to be done (better event logging, out of image logging, performance issues), but, as it is, it can be used for tracing almost any code in the image, even ones which may lock-up the image when halted (beware : bugs in the tracer may still lock or crash the image). It is also a very pedagogic way of seeing a full execution through a set of methods.
