Change multiple inspector tabs at once
by Peter UhnÃ¡k Nov. 2, 2015

Nov. 2, 2015

Is it possible/planned to change multiple GTInspector tabs at once? For example: â I would like to click on the next item in the leftmost pane, but keep the middle and right panes opened, just update the data to reflect the newly selected item. I imagine there could be a "pin" button on each tab that would keep it open or something, but maybe that would not be easy to implement. Thanks, Peter

VM crash on Ubuntu 14.04
by Johan Fabry Nov. 2, 2015

Nov. 2, 2015

Hi all, I am having some unpleasant experiences on Ubuntu 14.04 (experimenting with Live Robot Programming on PhaROS). The VM crashes after a random amount of time (< 25 minutes), with no clear sequence of steps on how to reproduce the crash. I am using Pharo 4 (Pharo 40622 as installed by PhaROS) + Roassal which required an install of libcairo2:i386 . VM version details below. There is no printout on stdout, and the debug.log does not contain recent entries (timestamp is always some minutes before the actual crash happens). Is this a known problem? If so, how can I fix it, and if not how can I provide more debugging info? Thanks in advance! vm version: 3.9-7 #1 Thu May 15 18:29:30 CEST 2014 gcc 4.6.3 [Production ITHB VM] NBCoInterpreter NativeBoost-CogPlugin-GuillermoPolito.19 uuid: acc98e51-2fba-484 1-a965-2975997bba66 May 15 2014 NBCogit NativeBoost-CogPlugin-GuillermoPolito.19 uuid: acc98e51-2fba-4841-a965-2 975997bba66 May 15 2014 https://github.com/pharo-project/pharo-vm.git Commit: ed4a4f59208968a21d82fd2406 f75c2c4de558b2 Date: 2014-05-15 18:23:04 +0200 By: Esteban Lorenzano <estebanlm@ gmail.com> Jenkins build #14826 Linux pharo-linux 3.2.0-31-generic-pae #50-Ubuntu SMP Fri Sep 7 16:39:45 UTC 201 2 i686 i686 i386 GNU/Linux plugin path: /home/jfabry/catkin_ws/src/pharo/vm/ [default: /home/jfabry/catkin_ ws/src/pharo/vm/] ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Ring question
by Thierry Goubier Nov. 2, 2015

Nov. 2, 2015

I'm trying to look into Ring implementation. So I have a first question. Why is RGAbstractContainer and subclasses irregular? Is that on purpose? Details: RGAbstractContainer delegates adding a new element to the element being added, via aRGElement>>#addInContainer:. This element is then expected to use RGContainer>>#addTrait:/#addPackage:/#addMethod: etc... However only a subset of the RGElements implement #addInContainer:; for example, RGTrait does not implement #addInContainer: (*). (*) Ok, RGContainer>>#addTrait: calls RGContainer>>#addClass:, and RGTrait being a subclass of RGBehaviorDefinition, that works. But I'm still ?? Thierry

Multiple method deletion
by Alexandre Bergel Nov. 2, 2015

Nov. 2, 2015

Hi! When I select several methods in Nautilus, and press cmd-m-x it seems to delete more method that I have selected. It makes me lose code :-( Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
