Pharo 3.0 on Raspberry Pi - Yes/No
by Sven Van Caekenberghe Jan. 26, 2014

Jan. 26, 2014

Hi, Here is another step forward in getting Pharo 3.0 to run on a Raspberry Pi. Yes: pi@raspberrypi ~/Pharo-3.0 $ ../PharoRPi/PharoS -vm-display-null -vm-sound-null Pharo.image eval 'SystemVersion current' Pharo3.0 of 18 March 2013 update 30710 pi@raspberrypi ~/Pharo-3.0 $ ../PharoRPi/PharoS -vm-display-null -vm-sound-null Pharo.image eval 'ZTimestamp now' 2014-01-20T18:21:50Z No errors. No: When doing something more complex, like: pi@raspberrypi ~/Pharo-3.0 $ ../PharoRPi/PharoS -vm-display-null -vm-sound-null Pharo.image eval --no-quit 'ZnServer startDefaultOn: 1701' a ZnManagingMultiThreadedServer(running 1701) The HTTP Server does respond normally to one request and then seems to hang. When running with a UI, the image comes up, draws everything but remains unresponsive otherwise. No PharoDebug.log output. Events ? Multi-processing ? How ? Use Jean-Baptiste's VM from here: https://ci.inria.fr/pharo-contribution/view/RaspberryPi/job/RaspberryPi-Com… Take a stock 3.0 image and apply Pavel's unloadNB.st script (see the thread with subject unload all). So, we're getting closer... If anyone is interested, I could make some kind of all in one download. Sven

Bad naming: users
by Stephan Eggermont Jan. 25, 2014

Jan. 25, 2014

I tried loading Deltawerken in Pharo 3.0 and noticed it is now impossible to load code where a class side method is defined named users. DEUser class>>users ^self subclassResponsibility Stephan

12259: FileSystem memory reads writesusing a binary stream by default
by Max Leske Jan. 25, 2014

Jan. 25, 2014

Damien, Marcus this change breaks a lot of things in FileSystem-Git. I donât disagree with the idea that reading characters should be default (one could argue about itâ¦) but your change makes it IMPOSSIBLE to read bytes because unprintable characters are discarded! So if my ByteArray is a NULL terminated string, for instance, I can not check for the NULL termination anymore. Cheers, Max

fun with update:
by Pharo4Stef Jan. 25, 2014

Jan. 25, 2014

During my analysis of update: methods (I started to extract conditional leaves : simple refactoring no change) and I found the following We are lucky because this is SimpleHierarchicalListMorph and I prefer not to think about ComplexHierarchicalListâ¦ update: aSymbol aSymbol == getSelectionSelector ifTrue: [self selection: self getCurrentSelectionItem. ^self]. aSymbol == getListSelector ifTrue: [self list: self getList. ^self]. ((aSymbol isKindOf: Array) and: [aSymbol size > 1 and: [aSymbol first == getListSelector and: [ aSymbol second == #openPath]]]) "allow directed path opening where multiple trees exist" ifTrue: [^(scroller submorphs at: 1 ifAbsent: [^self]) openPath: (aSymbol allButFirst: 2)]. ((aSymbol isKindOf: Array) and: [aSymbol size > 1 and: [aSymbol first == getListSelector and: [ aSymbol second == #openItemPath]]]) "allow directed path opening where multiple trees exist" ifTrue: [^(scroller submorphs at: 1 ifAbsent: [^self]) openItemPath: (aSymbol allButFirst: 2)]. ((aSymbol isKindOf: Array) and: [aSymbol notEmpty and: [aSymbol first == #openPath]]) ifTrue: [^(scroller submorphs at: 1 ifAbsent: [^self]) openPath: aSymbol allButFirst]. ((aSymbol isKindOf: Array) and: [aSymbol size = 2 and: [aSymbol first = getListSelector and: [ aSymbol second == #expandRoots]]]) ifTrue: [^self expandRoots]. ((aSymbol isKindOf: Array) and: [aSymbol notEmpty and: [aSymbol first = getListSelector and: [ aSymbol second == #expandAll]]]) ifTrue: [^self expandAll]

HandMorph ShowEvents
by Sean DeNigris Jan. 25, 2014

Jan. 25, 2014

Is there a reason that the HandMorph class>>showEvents: feature draws directly on the screen instead of opening a Morph? Am I missing a use case, or would it be okay to turn this into a proper Morph?

more code reviews :)
by Pharo4Stef Jan. 25, 2014

Jan. 25, 2014

Hi marcus I agree with you. Sometimes I look at the code and I cannot help deciding if I would integrate it or not. :) For example the opal or compiler parser changes. Marcus may be we should just go slower. It takes times to have energy to have a look at a change. I would like that we take more time to do code review. May be in the future we should change the way we work: integrate only changes that have got more than two ok? I do not know, what I know is that I want to read the code of the changes I push because I want to slowly learn just by reading (without understanding much) the parts of the system I do not know. This is a gigantic task but I do not see how else we can do to learn. Stef

TraitComposition equality
by Martin Dias Jan. 25, 2014

Jan. 25, 2014

Hi, I want to determine if a trait composition is different than other, for example: newClass traitComposition = oldClass traitComposition But I didn't find an implementation. I imagine the simple implementation that checks that all of its components are equal recursively. The components are instances of either Trait, TraitAlias or TraitExclusion, and it should be simple to define = on each of them. Do experts on traits agree? I can open an issue and propose a slice. This arose when looking into issue 12157, where the problem is that ClassModifiedClassDefinition is always announced because the trait composition *may* have changed. This way, ClassModifiedClassDefinition is announced even when it was a class creation. We could also workaround the lack of trait composition equality by comparing their 'asString's... Bests, MartÃn

Font chooser broken (12704)
by Nicolai Hess Jan. 25, 2014

Jan. 25, 2014

Sean, can you look at my latest submission for 12704. There were some types in your slice := instead of = or each value: aBlock instead of aBlock value:each And an error with Announcements for FontChooser that were sent to the PluggableListMorph too. nicolai
