model vs interactionModel in rubric

by Andrei Chis

Hi, RubScrolledTextModel fails sometimes if the model does not have an interaction model set. For example in a few places there is a check that verifies if the model understands a message and then the message is send to the interaction model. evaluate: aStream andDo: aBlock .... (self model respondsTo: #doItReceiver) "check on the model" ifTrue: [ rcvr := self model doItReceiver. ctxt := self model doItContext] And then doItReceiver is implemented like: doItReceiver ^ interactionModel ifNotNil: [ :im | im doItReceiver ] "message send to the interaction model" Also in some cases a condition is checked on the model and then the actual result is obtained from the interaction model: (self model systemNavigation allImplementorsOf: aSelector) isEmpty ifTrue: [ self internalCallToBrowse: aSelector ] ifFalse: [ self model interactionModel systemNavigation browseAllImplementorsOf: aSelector ] I'll say these are bugs. Also should a RubScrolledTextModel always have an interaction model? Cheers, Andrei

Debian 8 Jessie ia32-libs is not available

by Ben Coman

Installation instructions [1] for Debian 8 Jessie 64-bits currently says... sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install ia32-libs sudo apt-get install libx11-6:386 sudo apt-get install libgl1-mesa-glx:i386 sudo apt-get install libfontconfig1:i386 sudo apt-get install libssl1.0.0:i386 However I get an error... ia32-libs is not available The top answer at [2] describes why... The ia32-libs package was a hack to get 32-bit packages installed on a 64-bit installation. Since Ubuntu version 11.10 (Oneiric), Multi Arch has been added. One of the objectives for it is removing the ia32-libs package. [1] http://pharo.org/gnu-linux-installation [2] http://askubuntu.com/questions/107230/what-happened-to-the-ia32-libs-package and indeed, after removing that line, the following worked for me... sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libx11-6:i386 sudo apt-get install libgl1-mesa-glx:i386 sudo apt-get install libfontconfig1:i386 sudo apt-get install libssl1.0.0:i386 Could this perhaps be updated on the web site. btw, note that libx11-6:386 is missing an "i" I've logged https://pharo.fogbugz.com/default.asp?17198 cheers -ben

context menu keyboard key

by Peter Uhnak

Hi, is there a way to open context menu without using mouse/right click? Keyboards generally have a special key for this, but Pharo doesn't seem to even recognize the keypress. To anyone familiar with this, can this be fixed in image? Or digging into VM is needed? Thanks, -- Peter

Very interesting idea, bug bankruptcy. We certainly suffer from it where I work. As for the bug, I'd just like to thank Nicolai for taking the time to investigate it and work out a fix. -- View this message in context: http://forum.world.st/issue-12231-DisplayScreen-hostWindowTitle-not-working… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

What everybody should understand is that context switch is difficult and cost a lot of energy. So making clear what is the next step for an action is really important. It helps people to follow.

Not a good message to send > out. You are right, its not ideal. On the flip side, from the issue history it appears that Nicolai took the time to dig into the problem, understand it and provide a fix. So your report was not ignored. Closing the bug unfixed would also waste that effort of Nicolai's, but since he is the one who donated his time on your behalf, I believe he is entitled to make that call to moderate "bug bankruptcy" per [1]. Thats how open source works. Now it would be *real*nice* if we had a bug bounty system where you could prioritize bugs important to you, but in the meantime, if the issue had no progress for two years, its an important question to ask how likely is it to progress further on its own. We can't do everything and a bug backlog consumes resources to manage. So while Fogbugz is good as a tracker and a historian, its useful to socialise issues on the mail list from time to time to help prioritise them. Anyway, it seem Nicolai's mail had the desired effect of bumping it on an action list. [1] http://www.joelonsoftware.com/items/2012/07/09.html cheers -ben
