[Pharo-project] Multiselect in method pane
by Norbert Hartl March 28, 2013

March 28, 2013

What is the rationale for having the method pane as multi-select list? I don't think it is of greater use when editing code. I could imagine that some refactoring tasks could be easier having multi-select lists. Anyway, if I try to rename a method without using the refactoring engine I just change the selector, save and delete the method with the old selector. In pharo 2.0 when you rename a method and then click on the old selector both methods are selected and shortcut invocation for deleting deletes both. Which is quite annoying. In my opinion there is no reason for two methods being selected. If you agree I'll happily enter a bug. Norbert

[Pharo-project] Looking for a Seaside 3.1 Configuration for Pharo 2.0
by StÃ©phane Ducasse March 28, 2013

March 28, 2013

Hi guys we would like to use seaside to validate the VM and also make sure that Seaside31. works perfectly in Pharo2.0. I saw that some of you have a working configuration. Where can we find it because we would like to publish it in the MetaRepoForPharo20. Stef

[Pharo-project] Nautilus: Class Side vs. Instance Side
by Mircea Filip Lungu March 28, 2013

March 28, 2013

Hi people, I've installed Pharo 2.0 to give it a try. All good until now! Looking at Nautilus I see that where there used to be two buttons for switching between class-side and instance-side methods, now there is a checkbox. As I was slowly trying to get used to it... it occurred to me that I would have liked even more if I would not have to switch at all. In fact it would be so much nicer to see everything about a class at once. One solution might be splitting the protocols panel in two for instance and class side. Just my 2C.

Where can we find it because we would like to publish it in the >MetaRepoForPharo20. We have it working, but it does not have the Seaside Panel (& browser). At last Esug Seaside sprint I started redoing them in Spec, but never managed to spend more time on them. They are in the Seaside31 repository on squeaksource: Seaside-Pharo-Tools-Spec (might need renaming to Pharo20). Stephan

[Pharo-project] strange problem in CompiledMethod>>=
by Tudor Girba March 28, 2013

March 28, 2013

Hi, One of the Moose test runs a visualization that manipulates CompiledMethods, and it runs into an error when trying to find an entry inside a dictionary that has compiled methods as keys. In the end, I managed to isolate the problem that can be reproduced by: 1. Download the moose image: https://ci.inria.fr/moose/job/moose-latest-dev-4.8/lastSuccessfulBuild/arti… 2. Execute: (MooseIncomingQueryResult>>#selectDependencies:) = (MooseOutgoingInvocationQueryResult>>#selectDependencies:). It seems it is a Pharo problem, or something related to these particular methods. Would anyone be interested in looking into this?
