doing stupid things (image will become unusable)
by Nicolai Hess June 1, 2016

June 1, 2016

Object := nil you can evaluate that piece of code, but afterwards .... Opal checks for assignments to read only variables (method arguments for example) and signals an error if you try to modify those vars. But it does not check globals. Should all Globals (OCLiteralVariable with isGlobalVar == true) be read only ? or can we distinguish global vars and class bindings?

Some GT tool for this?
by Mariano Martinez Peck April 21, 2016

April 21, 2016

How many times have you tried to search a string as a comment of a commit in all the history? Myself: many many times. I know we need much better tools for that, store the history in a another way, provide a nicer API, etc etc. And I know there were topics about that. However, I would deeply appreciate a very short term solution for ease that. The model side is as simple as this: | packageName ancestry anscestors substring | packageName := 'MyPackageXX'. substring := 'whatever I want to search'. ancestry := (MCWorkingCopy allManagers detect: [:each | each packageName = packageName] ) ancestry. anscestors := ancestry withBreadthFirstAncestors select: [:each | each isKindOf: MCVersionInfo]. anscestors select: [ :each | each message includesSubstring: substring ] Do you think it's worth a simple UI tool? Custom inspector of MCAncestry? Cheers, -- Mariano http://marianopeck.wordpress.com

SessionManager (aka new startup / shutdown list manager) needs testers
by Christophe Demarey March 25, 2016

March 25, 2016

Hi, Guillermo, Pablo and I started to work on a new implementation for the image startup / shutdown list. The old implementation misses domain objects, polluted the SmalltalkImage class and introduced crazy dependencies to other packages. So, what is Session Manager? a replacement of the Session class (is now WorkingSession) a rewrite of startup / shutdown list with domain objects SessionManager: can create new sessions and manage categories. Also provide a facade to register new session handlers. Session manager provide sthe list of handlers by order of priority (categories order and categories priority) either for the startup or the shutdown, WorkingSession: unique object for the current smalltalk session (I.e. between a startup and a shutdown). On each image startup the current session is invalidated and a new session is created. Define how errors should be handled. Run the startup / shutdown process. SessionCategory: we defined some well known categories for startup / shutdown: system, network, GUI, tools and there is room to add user specific categories, It help to run the handler at the right time without caring about the whole order. and SessionHandlers: handleSession for a specific class or any other object. the shutdown list is now simply the startup list reversed we also refactored error handling at startup by using the UIManager and StartupUIManager. It allowed to remove ugly checks like #isInteractive, isHeadless in error handling methods and centralize that in UIManager. You can find an image with the new SessionManager in action here: https://ci.inria.fr/pharo-contribution/job/SessionManager/ As it is a critical piece of code, could you play / test it a bit before we integrate this new mechanism in the Pharo image? Regards, Christophe ps: Pharo tests pass ps2: There is still some code to clean / remove from the old startup management system.

Rubric mutability issue in RubTextComposer binary search
by Aliaksei Syrel March 5, 2016

March 5, 2016

Hi, seems like there is a rather rare bug in Rubric. I opened an issue with explanation: https://pharo.fogbugz.com/f/cases/15153/Rubric-mutability-issue-in-RubTextC… Would be nice to fix it until release. It was caught in Spotter - as it heavily uses multithreading. Any suggestions are welcome if it is known :) Cheers, Alex

Differences Compiler vs. OpalCompiler (or parser)
by Nicolai Hess Feb. 24, 2016

Feb. 24, 2016

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.

fixing our tools
by Nicolai Hess Jan. 27, 2016

please take a look at this errors: (I don't want to open 20 bug entries, and I think those issues are related to two changes for Suggestions menu and one problem on rubric (the current menu builder does not work for all tools where rubric is used) So, maybe there are only 2 or 3 "real" issues. Help appreciate, especially for the rubric issue. Every time I tried to fix one tool, there is at least one other tool with a broken menu. Open Nautilus on a method: (Morph>>#drawOn:) browse without any other interaction, right click on the code pane -> a menu appears with embedded "why you see this menu/debug" debug menu caused by empty selection interval as soon as you select once one method entry, the right click menu works again.
