Reacting to multi-selection changes in ListModel
by Yuriy Tymchuk Nov. 16, 2016

Nov. 16, 2016

Hi, maybe someone can help me out with this. Iâm working with ListModel that supports multiple selection and has autoDeselect turned off. Now Iâve tried to use #whenSelectionChanged: but it doesnât give any data, #whenMultiSelectionChanged: is not triggered at all, #whenSelectedItemChanged: works as for single selection list. Iâd be very thankful for any help. Uko

GTInspector table hides columns
by Peter UhnÃ¡k Oct. 30, 2016

Oct. 30, 2016

Hi, apparently inspector is happy to hide columns if they don't fit. Why is there no vertical scrollbar? â Also (I know I brought up this in the past, but the problem still remains), why does "Description" takes up so much space even though there's no data at all? Why not cap it at the width of the heading? Thanks, Peter

moving to Rubric in Glamour
by Andrei Chis Oct. 3, 2016

Oct. 3, 2016

Hi, I moved Glamour to Rubric, deprecated those presentations that use PluggableTextMorph and moved almost all usages of presentations that rely on PluggableTextMorph. These changes are still only in the Moose branch to see if there are any ugly bugs. The changes to the glamour API are the following: - deprecated #smalltalkCode, #pharoPlayground and #rubricText - added #pharoScript If you use #smalltalkCode replace it with either #pharoMethod or #pharoScript If you use #rubricTest replace those usages with #text If you use #pharoPlayground replace those usages with #pharoScript (we changed this as the glamour playground is not the same at the GTPlayground and this was causing some confusion) For this I also renamed GLMPharoPlaygroundPresentation to GLMPharoScriptPresentation and GLMMorphicPharoPlaygroundRenderer to GLMMorphicPharoScriptRenderer. If you are using the latest moose let me know if you run into any problems or have questions. Cheers, Andrei

Another just arrived, so I thought I'd share it again. In another half year I guess I'll get another, so if anyone doesn't want me to post again then, let me know. More background info... ABC is Australia's government sponsored national TV broadcaster (yay, no commercials!). They produced a web site to help kids literacy. It was fantastic for my kids, although my 8 year old got bored with it later on, so it seems more suited for younger ages. The 4 week free trial is advertised "No credit card required." An annual subscription is AU$80. http://readingeggs.com.au/taf/?utm_source=Aprimo&utm_medium=Email&utm_campa… cheers -ben

Interrupting process which hangs on recursion
by Denis Kudriashov Sept. 19, 2016

Sept. 19, 2016

We had discussion on reasons why cmd+. is not always working. I made simple test which shows that VM is not issue. Following code normally stops after 20 seconds: hanging := [1 seconds wait. 1 recursionTest] newProcess. hanging priority: Processor activePriority + 10. interruptor := [ 20 seconds wait. hanging suspend] newProcess. interruptor priority: Processor activePriority + 11. hanging resume. interruptor resume. Recursion method: Integer>>recursionTest self recursionTest Hanging process produces 7 million contexts on my machine: c := hanging suspendedContext. count := 1. [ c notNil ] whileTrue: [ c := c sender. count := count + 1 ]. count Â«7395279" But if you try to debug it by "hanging debug" you will see how it is slow. It's caused by printing stack to file. Interesting that logging is performed before opening debugger. So every time we press cmd+. we are waiting logging to see debugger. We need to change this logic. Best regards, Denis

by Thibault ARLOING Sept. 17, 2016

Sept. 17, 2016

Hello, I'm happy to announce the latest release of Pillar. This release has been possible because of the hard work of Damien Cassou, Cyril Ferlicot, Yann Dubois, Thibault Arloing and Lukas Komarek. What did it bring and what are the largest changes ? * Huge cleaning of code and Dependencies * Many bug fixes * Huge refactoring of internal parts * Extract phase management into an external project (LightPhaser) * Transformers and Phases are all Pipes Remove Compilation cycle * Remove template handling from Pillar * Remove generation of pillarpostExport.sh * Pillar now exports files to JSON format * Command for pillar archetypes "./pillar archetype book", book can be replaced by other archetype names (see Pillar documentation) * Possibility to load an archetype with a Makefile to compile pillar files Features * Check phase to check syntax * EPub exporter for e-books (use pillar archetypes for this) * Semantic links to Youtube and Wikipedia * Citations for LaTeX * Structures (see Pillar documentation) * Footnotes for HTML, Markdown, LaTeX and AsciiDoc * Improvement of parsing configuration failure message Major changes * Metadata field in configuration to separate data from configuration properties * Support files in configuration does no longer exists * "disableTransformers" property is now named "disabledPhases" * AsciiDoc file extension is now ".asciidoc" * Pillar now manages one input file, not a collection of input files anymore * Parameter inputFiles is now replaced by inputFile The documentation of Pillar will be update as soon as possible to fit those changes. Cheers, Thibault

[ann] pillar support in gtinspector
by Tudor Girba Sept. 15, 2016

Sept. 15, 2016

Hi, I updated the Pillar support in GTInspector. Some of the extensions already exist in the default Pillar #development version. If you want to play with the full support, you can load it like this: Gofer new smalltalkhubUser: 'Moose' project: 'PetitParser'; package: 'PetitAnalyzer'; package: 'PetitIndent'; package: 'PetitIslands'; smalltalkhubUser: 'Moose' project: 'GToolkit'; package: 'GT-InspectorExtensions-Pillar'; load Then you can just inspect a book folder and you get this: I did not integrate this in the main Pillar yet because this is an older implementation based on a limited island parser. As now Pillar has a full parser based on PetitParser, the next step is to move the highlighting logic to use this parser instead of the island parser. From my measurements, the speed of the two parsers is about the same, so from a user perspective there will be not much changes. It pains me that we are editing Pillar in outside tools, and now we should no longer have to do that. Of course, this is not the most ideal tool support for Pillar but I think it is a reasonable start.

SUnit improvements need review and feedback
by Denis Kudriashov Sept. 9, 2016

Sept. 9, 2016

Hi. I am working on SUnit improvements. I open issue 19015 <https://pharo.fogbugz.com/f/cases/19015/Tests-should-never-hang-and-leave-f…>. Slice is inbox which waits your review and feedback. I was trying to address three problems: *1) Tests should never hang. They should be always executed within time limit.* I give them 10 minutes for now to not change existing behaviour of tests. At next step it should be really reduced to ~100 milliseconds (?). Any TestCase could redefine time limit by method #defaultTimeLimit. Or it could be specified directly in test code by self timeLimit: 10 seconds (could be changed at any time of test execution). To implement this logic special watch dog process is running for given test suite to control execution time of tests. It is single process for full test suite. *2) When test completes all forked processes should be terminated.* If your tested code produced zombie processes SUnit will take care about destroying all such garbage. (it not means that you don't need to clean table in #tearDown but any code could be broken and running tests should not produce dirty system). *3) Any failures inside forked processes should not spawn debugger while running tests.* Only when we debug tests we need debugger on forked failed processes. During normal run SUnit should prevent such "background debuggers" and mark such tests as failed. To implement this behaviour SUnit will handle errors from forked processes by suspending them and collecting them in special collection. I introduce TestFailedByForkedProcess error to signal these kind of problems at the end of tests. This error is resumable and resume will opens debuggers of suspended failures (in fact it will resume suspended processes). So to debug background failures you will need extra Proceed action on debugger when TestFailedByForkedProcess is signalled. But in normal run such tests will be just failed by TestFailedByForkedProcess error. *Now details on how it is done:* I introduce special process specific variable CurrentExecutionEnvironment. It is not installed by default and as default value it returns DefaultExecutionEnvironment instance. This variable is inheritable. If your install concrete environment into process it will be installed to any child process. So value of variable is instance of ExecutionEnvironment subclasses and you can install it by: anYourExecutionEnvironment beActiveDuring: aBlock When block completes previous environment is restored. For default environment there is class side method: DefaultExecutionEnvironment beActiveDuring: aBlock And to reset current environment to default: DefaultExecutionEnvironment beActive. SUnit introduces TestExecutionEnvironment which implements all described behaviour for time limits and forked processes. To activate environment there is new method #runCaseManaged. And submitted slice uses it instead of simple runCase. TestCase>>runCaseManaged CurrentExecutionEnvironment runTestCase: self DefaultExecutionEnvironment will install new TestExecutionEnvironment and delegate processing to it. And if TestExecutionEnvironment is already active it will just process new test case. Now monkey has problem in checking slice (annoying timeout for loading). So I can't see real system impact. But it should not stop you from review :)) I think it is very important features for all our tests. And environment idea will lead to very interesting future. Best regards, Denis
