Community Building [was: please name your thread]
by EuanM Dec. 7, 2015

Dec. 7, 2015

Tudor, You say that we are talking about different mails. I hope so. "We need to focus on building a great platform." "acting is the only thing that will push us further.". I agree that action is what achieves things. To make sure the correct actions are taken, in a productive and efficient way, it can be valuable to take stock and think, periodically. It is important to carry out a variety of actions, not solely coding. Too narrow a focus on keeping a small group of people coding as fast as they can is not the fastest path to the end goal. It can easily lead to improving the platform at a slower rate than other great platforms are improving - a process of relative decay. I would like to help with community building efforts. But unless the leaders of the community also help and prioritise such efforts, they are unlikely to make any difference. There is no point gaining the interest of new people unless we have mechanisms in place to make them welcome, and put them on the path to becoming valuable contributors to the community. Small communities with low levels of resource must, to succeed, do things more efficiently than large groups with lots of funding. Currently, we lack: 1) debugged beginner's training materials. 2) community processes for getting the interest of new people 3) community processes for onboarding interested new people with the lowest loss rate 4) community processes for providing positive feedback and encouragement to people taking these actions. 5) community processes for stopping bit-rot in mature libraries and facilities - including key facilities like SqueakSource, Smalltalkhub and SqueakSource3 6) community processes to help focus resources on merging libraries into a single best-of-breed best-of-breed mature libraries. We often have two competing incomplete libraries for any given problem space, e.g. Spec/Bloc, MuTalk / SMutant 7) community processes to document the community processes 8) documented processes for bringing newcomers up to speed with "the way things are done round here" We need to take these issues seriously - they affect how fast things get done around here much more than this amount of time away from decoding Pharo-core does Closing down all discussions where these issues surface does not communicate "We welcome any action that anyone would want to undertake in this direction". Quite the reverse. We need to do more than just Smalltalk the Smalltalk - we need to walk the walk.

model vs interactionModel in rubric
by Andrei Chis Dec. 6, 2015

Dec. 6, 2015

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

textColor: overrides the color attribute of the Text object
by Andrei Chis Dec. 6, 2015

Dec. 6, 2015

Hi, Consider the following two code snippet below: [1] (RubScrolledTextMorph new textColor: Smalltalk ui theme textColor; setText: (Text string: 'a b c' attributes: {TextColor green}); yourself) openInWorld. [2] (RubScrolledTextMorph new setText: (Text string: 'a b c' attributes: {TextColor green}); textColor: Smalltalk ui theme textColor; yourself) openInWorld. In the first case the color of the text is the one from the theme, while in the second the color is green. So if set after the text object, the textColor attribute overrides the actual color of the text. Is this the expected behaviour? With PluggableTextMorph the color of the text object always tool priority over the #textColor atribute of the text morph. Cheers, Andrei

Debian 8 Jessie ia32-libs is not available
by Ben Coman Dec. 6, 2015

Dec. 6, 2015

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 Dec. 6, 2015

Dec. 6, 2015

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

Dec. 6, 2015

see bug report 12231, I added a fix for the unix config. But it has to applied by someone. (I don't know where to put this else). But the issue is two years old, if no one responds, I'll just close the issue.
