Google building new OS with Dart
by askoh Aug. 24, 2016

Aug. 24, 2016

It became news a few days ago. It is called Fuchsia and is meant to run on all devices from IoT on up. The interesting thing is that Dart will be the main language. The developers promise to make Fuchsia run on Raspberry Pi 3 shortly. Since Dart is pretty close to Smalltalk, how can Smalltalk be the GUI for Fuchsia? How can it take advantage of Dart VM? Is this an opportunity for Smalltalk to make an impact? Let's brainstorm. All the best, Aik-Siong Koh -- View this message in context: http://forum.world.st/Google-building-new-OS-with-Dart-tp4911649.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Keyboard work flow?
by epeld Aug. 23, 2016

Aug. 23, 2016

Hello! Is it possible to get by using ONLY the keyboard in the standard development components? Here are some workflows that I frequently use and would like to perform without mouse if possible: 1. Use Spotter to browse a class 2. Define a new method. That is, allow me to immediately focus the source code editor so I can start typing a new method or 1. Use Spotter to browse the implementation of a method 2. Edit its source code and accept 3. Now recategorize or rename or create new class etc etc. (the problem here is that the source code editor will shadow all the shortcuts I normally have in the browser, e.g CMD-M CMD-M would normally recategorize the method, but now this brings up the implementors list instead. Thanks! -- View this message in context: http://forum.world.st/Keyboard-work-flow-tp4912091.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Spec > TreeModel: Updating the tree selection after a deletion
by Offray Vladimir Luna CÃ¡rdenas Aug. 23, 2016

Aug. 23, 2016

Hi, I have a Spec TreeModel to represent the GUI of a grafoscopio notebook. The message that deletes nodes is something like this: ============ GrafoscopioNotebook>>removeNode | nodeToDelete | nodeToDelete := tree selectedItem content. nodeToDelete parent removeNode: nodeToDelete. tree selectedItem: tree selectedItem parentNode. tree needRebuild: true. tree roots: tree roots. self buildWithSpecLayout: self class defaultSpec. ============= And its working fine in the sense that it deletes the selected node, but after the deletion the contents of the old node are showed no matter if I change the node selection on the tree. I would like to manage selections in a smart way, so if I add a new node to the notebook, the new node gets the selection. If I delete a notebook node, the previous node gets selected or the parent if no more siblings are encountered and so on. There is some simple example to look for, about managing and updating selections in a TreeModel interface? Thanks, Offray

Pharo 5 and image resizing
by phil＠highoctane.be Aug. 23, 2016

Aug. 23, 2016

I am going to start a new project using Pharo. Two choices for me: * use the trusty Pharo 3 stack that I have * embark on Pharo 5 w/ new Seaside etc I need PetitParser and such things and saw a new Moose release based on Pharo 5, so maybe I should start there. I've a concern with the image resizing in Pharo 5, as when I'll be loading several (tons of) packages, MCZs will be piling up and if clearing that cache isn't going to reduce the size of the image, I am not really keen on dragging these around. This will just get worse over the course of the development. Any news on that front? Phil

Re: [Pharo-users] Pillar question: PRCitationTransformer
by Yann Dubois Aug. 22, 2016

Aug. 22, 2016

Hi stef, You can not have a citation annotation on a writer because the annotation is transformed before to a PRCitation object. So you need to overwrite visitCitation. PRCitationTransformer is called in the phase mechanism. He is added in the transform pipeline. PRCitationTransformer will be rename to PRCitationAnnotationTransformer because this class change the citation annotations and not the citations. Le 22 aoÃ»t 2016 07:36, "stepharo" <stepharo(a)free.fr> a Ã©crit : Hi I'm trying to extend Pillar to get new $publications:...$ structure and it looks like Pillar is getting more and more complex. And the comments do not really help because they are short and written for someone already understanding it. :( To try to understand I tried to ! Youpi ${cite:ref=Duca18rmod}$ !! Others but I get {"content":"!Youpi\n\n\n\n!!Others"} ./pillar export --to=pillar Example.pillar May be I cannot export to pillar a citation. I have no idea. I tried to add PRPillarWriter >> visitCitationAnnotation: aCitation "We invoke visitAnnotation: to make sure that the rest of the document is visited." self halt. super visitCitationAnnotation: aCitation Did not stop! So I put an halt into PRVisitor >> visitCitationAnnotation: aCitationAnnotation self halt. self createNewCitationWith: aCitationAnnotation. self replace: (OrderedCollection with: tmpCitation) . super visitCitationAnnotation: aCitationAnnotation and it stopped. I tried to understand who is calling PRCitationTransformer No luck. I'm sure that there is a magic registration mechanism but I failed to find it. Looking at tests (BTW Tests are not documentation or class comments, there are tests). It looks like I need a configuration. (self actualClass executeOn: (PRCompilationContext withDocument: anInput withConfiguration: aConfig)) input And then I fall on executeOn: implementors..... LLPhase and PRNodeTransformer. and I have no idea how a Phase relates to a visitor. To bad, after all the efforts on Pillar it looks like getting too complex. So do not think that we can decently ask students to work on improving Pillar anymore because they will just get lost and disgusted from Pharo. :( Sad news isn't. I hope that I will not have to switch back to LaTeX or markdown (shit). Stef

Aug. 21, 2016

Hello, I have a bunch of packages into a group browse scoped. If I create a new class inside of one of the packages the, the full browse updates correctly to show the new class, but the browse scoped don't, I had to close it and scope again to see the new class, is this the correct behavior? I am using Pharo 5 in a windows 10 O.S. Regards, Vitor

Hi I published a new version of the webportal (a packaged version of the mooc) with the help of thibault. Now I'm about to test that all the videos have indeed the correct subtitles. If you want to give me a hand or simply have a look http://rmod-pharo-mooc.lille.inria.fr/MOOC/WebPortal/co/pharo.html Once everything will be verified we will push it to the mooc web page and announce it.

by Peter Uhnak Aug. 20, 2016

Aug. 20, 2016

Hi, is there any editor extension for Pillar that would show me the result version side by side with what I am typing, as I am typing it? (Also it has to be desktop editor, nothing online). Thanks, Peter
