GTDummyExamples class d: anInteger <gtExample> <label: 'Dummy #d:, depends #c:'> <description: 'should raise an exception as the argument is not anInteger'> <depends: #c:> <raises: Literal constant expected -> MessageNotUnderstood> ^ 1 + anInteger The old Parser complains about the class name "MessageNotUnderstood" used as a pragma argument without being a string or symbol Opal does not complain Is Opals behavior intended ? >From squeaks bugtracker : http://bugs.squeak.org/view.php?id=7770 Cascading message sends to super. Compiler refuses to compile super initialize; setListProperties It looks like Opal would compile this to super initialize. super setListProperties. Intended ? Do we want to keep it? NBNativeCodeGen parseOptions: optionsArray uses association symbol -> block instead of block -> block for caseOf arguments. The old parser does not accept this.

Re: [Pharo-dev] [Pharo-users] World lastKeystroke and openInWorld: aPasteUpMorph
by Nicolai Hess Feb. 20, 2016

Feb. 20, 2016

2015-06-11 10:58 GMT+02:00 Markus Schlager <m.slg(a)gmx.de>: > issues opened > I added a fix for the broken lastkeystroke,but this will only work for the ActiveWorld/PasteUpMorph, not for any other PasteUpMorph. With the split of PasteUpMorph in PasteUpMorph and WorldMorph, and the change of keystroke handling (KMDispatcher), there is more to do to make this fully work again - but I don't want to reintroduce the old keyevent handling just to make this work again. I would like to remove all the keystroke handling from PasteUpMorph/WorldMorph and use only KMDispatcher. Maybe there is another(new) way to make this "lastKeystroke"-demo? You can open a transcript and enable the KMLog (KMLog setDebug. Transcript open) It will log all(!) keyevents and print the matching keymapping actions. Or something like this: |m| m := Morph new. m openInWorld. m takeKeyboardFocus. m on:($r ctrl) do:[ m color:Color red]. m on:($g ctrl) do:[ m color:Color green]. m on:($b ctrl) do:[ m color:Color blue]. This will open a morph that changes its color on ctrl+r/g/b So, maybe we can remove the whole "lastKeystroke" handling and make demos/examples like the above one? > > Markus > >

missing cairo library in CI
by Peter UhnÃ¡k Feb. 14, 2016

Feb. 14, 2016

Hi all, not sure if this is best directed at pharo or CI mailing list... I've created a new job in pharo-contribution and my Pharo project uses Cairo library... however when CI ran the tests it failed on "Cannot locate cairo library. Please check if it installed on your system" ( https://ci.inria.fr/pharo-contribution/job/DynaCASE/2/PHARO=40,VERSION=deve… ) is it something I need to enable or disable somewhere? I'm pretty sure Athens also uses Cairo ( https://ci.inria.fr/pharo-contribution/job/Athens/) and it works just fine. Any pointers appreciated, Peter

[Pharo-project] [ANN] Pomodoro for Pharo 2.0
by Torsten Bergmann Feb. 5, 2016

Feb. 5, 2016

Hi, I followed the recent discussion and initial code about "Pomodoro" and since (until now) I used a timer written in Java I thought it would be a good idea to replace it with a Smalltalk one ;) I grabbed the HOPomodoro code from Phil and since it was marked as "experiment" I thought it would be good to write a new clean implementation with tests for Pharo 2.0. Thanks Phil - hope you are not angry that I hijacked the idea ... Attached is a screenshot of the tool. Install ======= Go to the Config browser in Pharo 2.0 ("Tools" -> "Config Browser") and load "Pomodoro" from the "Verified" tab. A new timer should appear and you can just click on "Start" to run the timer. When it finished it turns red, beeps and informs the user. How to use ========== You can open a new pomodoro (defaults 25 minutes) from the world menu ("Tools" -> "Pomodoro"). Customize ========= You can customize the pomodoro using Smalltalk. Here are a few examples: "open a new 25 minute one" Pomodoro new open "Opens a new timer with one minute total time" Pomodoro timerFor: 1 minute "Provide an action when pomodoro is finished" Pomodoro timerFor: 5 seconds whenFinishedDo: [ self inform: 'Pomodoro finished'] Code ==== The project comes with 15 tests. Code lives on project "Pomodoro" on SmalltalkHub. So far I added Phil and Sean as contributors since they discussed this topic already and may provide new ideas. If one wants to contribute feel free to do so. Thanks T.

last opened window does not go away
by Andrei Chis Jan. 6, 2016

Jan. 6, 2016

Hi, In the latest Pharo image there is a rogue instance of GLMSystemWindow. If I do in the console the following code I get one instance: /pharo Pharo.image eval "GLMSystemWindow allInstances" an Array(a GLMSystemWindow(58720256)) There are actually two windows, but one is RubFindReplaceDialogWindow and it should have no link with the glamour window. ./pharo Pharo.image eval "SystemWindow allSubInstances" an OrderedCollection(a RubFindReplaceDialogWindow(534511616) a GLMSystemWindow(58720256)) If I create another window that contains a morph that can take the focus then the glamour window disappears and the new window stays: ./pharo Pharo.image eval "(PluggableTextMorph on: ' ' text: nil accept: nil) openInWindow close. Smalltalk garbageCollect. SystemWindow allSubInstances" an OrderedCollection(a SystemWindow(234094592) an EditorFindReplaceDialogWindow(130547712)) Any idea if the find-replace service from rubric/textmorph holds one somehow to the last opened window or if there is another global cache that does it? Cheers, Andrei

EyeInspector with subclasses of ProtoObject
by Esteban A. Maringolo Jan. 3, 2016

Jan. 3, 2016

I'm dealing with the MessageArchiver of GLORP which is a subclass of ProtoObject and handles the "transparent" creation of expressions vÃa a DNU resolution. The problem I'm facing is that the EyeInspector expects the value in its value holder to respond to #basicSize, and because MessageArchiver inherits from ProtoObject it doesn't understand it. The problem is here: EyeInspector>>#variableFieldsToShow "Answers the indexes of the variable fields of the object to show. Shorten the list for very long collection (cf limit1 and limit2)" |bSize| bSize := self objectVariableSize. ^ bSize <= (self limit1 + self limit2) ifTrue: [1 to: bSize] ifFalse: [(1 to: self limit1) , (bSize - self limit2 + 1 to: bSize)]. If I implement #basicSize in MessageArchiver things go bananas. If I doesn't, and because #objectVariableSize is sent to MessageAchiver "proxy", bSize ends up with an instance of the MessageArchiver instead of an integer. I implemented #inspectorClass in MessageArchiver class to return EyeBasicInspector, but it is the same. Question: Is it documented what I should define/override in my classes to support EyeInspector? Regards, Esteban A. Maringolo pd: Stack trace =========== UndefinedObject(Object)>>error: MessageArchiver>>mustBeBoolean EyeBasicInspector(EyeInspector)>>variableFieldsToShow EyeBasicInspector(EyeInspector)>>addVariableFields: EyeBasicInspector(EyeInspector)>>generateElements EyeBasicInspector(EyeInspector)>>updateList EyeBasicInspector(EyeInspector)>>objectChanged [ self objectChanged ] in EyeBasicInspector(EyeAbstractInspector)>>initializePresenter in Block: [ self objectChanged ] BlockClosure>>cull: BlockClosure>>cull:cull: BlockClosure>>cull:cull:cull: BlockClosure>>cull:cull:cull:cull:

[ANN] Multiple Desktop support for Pharo 5
by Torsten Bergmann Dec. 21, 2015

Dec. 21, 2015

Julien Delplanque provided this week a goodie to switch between "desktops" - but his initial solution was more or less hiding windows and not really switching between real Pharo worlds/desktops. I gave him some tips what could be done on the pharo-user list. Havent heard from him afterwards. Now I was able to spend a few hours on this topic myself and implemented a full multiple desktop solution myself. This works in Pharo 5 only (currently) and requires latest VM (at least on Windows) from files.pharo.org to get the keyboard shortcuts right. To try: Gofer new smalltalkhubUser: 'TorstenBergmann' project: 'DesktopManager'; configuration; loadDevelopment. The goodie has some nice features like keyboard navigation, world menu integration and even a custom spotter with preview of the desktops. Quick start: =========== - evaluate the above expression in a Pharo 5 image - check the world menu "Desktop" - you can press CTRL + D and then CTRL + A (= Desktop Add) to add a new desktop - you can press CTRL + D and then CTRL + D (= Desktop Desktop) to open the overview - you can press CTRL + D and then CTRL + P (= Desktop Previous) to navigate to the previous desktop - you can press CTRL + D and then CTRL + N (= Desktop Next) to navigate to the next desktop The code is hopefully a good example on how to build a custom spotter, shortcuts, inspector extensions, ... Additionally all this is described in a new article including screenshots and a guide on how to use this new goodie: https://medium.com/@astares/multiple-desktops-for-pharo-5cbc46f3179f Actually the article took more time to write than coding but I hope it helps explaining Pharo and why it is a power tool. Project is on http://www.smalltalkhub.com/#!/~TorstenBergmann/DesktopManager Article and code is still subject to change. Have fun T.
