Hi, is it possible to include the vm-sound-OSS sound plugin in the cog build on Hudson?. This is the only plugin that seems to work on linux. Thanks. Daniel Galdames G.

[Pharo-project] Message cascades: can they be always transformed into a sequence?
by Stefan Marr Dec. 13, 2011

Dec. 13, 2011

Hi: I got a little problem with message cascades, and since I already missed a few details the first time, I wonder whether I am overlooking something now again. My question is, whether it is always possible to flatten a cascade into a surrounding sequence of statements (method/block). I am introducing temporary variables for that, and am wonder whether there could be anything I am overlooking with respect to the evaluation order. Thus, are there constructs where I would change evaluation order by pulling out normal sends and put the results into temporary variables? I obviously need to make sure that if I flatten them, that I order receivers and arguments correctly. Is there anything else that could hinder flattening? (Ah, and I am happy to ignore reflection, thisContext, or exceptions.) Here two examples: ---> original: testCascadedSends | assoc | assoc := Association key: #foo value: 0. assoc value: (1 + 2); value: assoc value + 2; value: assoc value + 5. self assert: 10 equals: assoc value. testCascadedNotInSequence | assoc | assoc := Association key: #foo value: 0. assoc value: (assoc value: 1; value: 2; yourself). self assert: assoc equals: assoc value. <--- ---> transformed: testCascadedSends | assoc t* | assoc := Association key: #foo value: 0. assoc value: (1 + 2). t1 := assoc value. assoc value: t1 + 2. t2 := assoc value. assoc value: t2 + 5. self assert: 10 equals: assoc value. testCascadedNotInSequence | assoc t* | assoc := Association key: #foo value: 0. assoc value: 1. assoc value: 2. t1 := yourself. assoc value: t1. self assert: assoc equals: assoc value. <--- Thanks Stefan -- Stefan Marr Software Languages Lab Vrije Universiteit Brussel Pleinlaan 2 / B-1050 Brussels / Belgium http://soft.vub.ac.be/~smarr Phone: +32 2 629 2974 Fax: +32 2 629 3525

[Pharo-project] allSharedPools
by StÃ©phane Ducasse Dec. 13, 2011

Dec. 13, 2011

This is a pity that allSharedPools does not return an ordered unique collection. Class>>allSharedPools "Answer a Set of the pools the receiver shares, including those defined in the superclasses of the receiver." | aSet | ^self superclass == nil ifTrue: [self sharedPools copy] ifFalse: [aSet := self superclass allSharedPools. aSet addAll: self sharedPools. aSet] since sharedPools returns now an orderedCollection I doubt that the uniqueness will the guaranteed. Behavior>>allSharedPools "Answer a Set of the names of the pools (Dictionaries or SharedPool subclasses) that the receiver and the receiver's ancestors share." ^superclass allSharedPools Now on a metaclass we will climb up the inheritance chain for nothing so I would define allSharedPools as follows ClassDescription>>allSharedPools "Answer a Set of the pools the receiver shares, including those defined in the superclasses of the receiver." ^ OrderedCollection new Tell me what you think?

[Pharo-project] Cleaning up SmartRefStream use
by Marcus Denker Dec. 13, 2011

Dec. 13, 2011

Hi, We should minimize the use of SmartRefStream... so we can remove it eventually. I already did a little bit (e.g. removing BitmapStreamTests). These are the next steps: Issue 5081: Remve Morph saving to file/loading http://code.google.com/p/pharo/issues/detail?id=5081 Anyone needs this? Issue 5084: Remove textStyle FileOut http://code.google.com/p/pharo/issues/detail?id=5084 Is this used? Strange corner of the system... lots of dead code. Issue 5083: remove unused methods from SmartRefStream http://code.google.com/p/pharo/issues/detail?id=5083 Towards removing it alltogether. -- Marcus Denker -- http://marcusdenker.de

You have to accept the security exception for the self signed certificate in FF or use the -k option for curl. Error handling is not good yet, you might have to restart the server. There was indeed still an error in ZnSecureSocketStream>>#accept as I expected. So use the very latest versions.

Hi guys I would like to see how we can clean the protocols. Behavior>>sharedPools "Answer a Set of the names of the pools (Dictionaries) that the receiver shares. 9/12/96 tk sharedPools have an order now" ^ OrderedCollection new => I will update the comment (this is not a set nor with names!) => I would like to move down to classDescription such methods because all the other methods are defined there or in Class. Class>>sharedPools "Answer a Set of the pool dictionaries declared in the receiver." sharedPools == nil ifTrue: [^OrderedCollection new] ifFalse: [^sharedPools] => I will update the comment TraitBehavior>>sharedPools ^ Dictionary new oops! I would be good to have polymorphic results! I will return ^ OrderedCollection new Now I'm not sure if it makes sense (but this is probably better) that RBClass returns also a polymorphic results. I have the impression that we get an orderedCollection too. RBClass>>sharedPools ^ self allPoolDictionaryNames collect: [ :each | Smalltalk globals at: each asSymbol ifAbsent: [ Dictionary new ] ] Ring seems to miss sharedPools. Stef

[Pharo-project] Script to migrate from squeaksource to squeaksource3
by Benjamin Dec. 13, 2011

Dec. 13, 2011

Hello guys, I would like to know if there is a way to script the creation of project on ss3 and the migration from ss to ss3. Cause it's well known that I am a lazy ass, and I do not want to have to recreate each project one by one by hand :) And I am pretty sure not to be the one trying to run away from squeaksource ;) Ben

The project was coded by several different students with different coding styles and barely any Smalltalk experience.

We've made our best to get what we could to work in Pharo, but we never tried to make the code better. > > You are definitively right Bernat, this is a good example that even in Smalltalk, this is possible to write nightmare code. Do we need another example after etoys? I really would have expected that someone involved in the original etoys would have known better than to *again* let a code base degenerate to the point that it is completely unmaintainable...
