About Matrix API access

Hi I'm wondering why | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 at: 1 at: 1 put: 11. matrix23 at: 1 at: 2 put: 12. matrix23 at: 1 at: 3 put: 13. matrix23 at: 2 at: 1 put: 21. matrix23 at: 2 at: 2 put: 22. matrix23 at: 2 at: 3 put: 23. is not equivalent to | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 atColumn: 1 atRow: 1 put: 11. matrix23 atColumn: 1 atRow: 2 put: 12. matrix23 atColumn: 1 atRow: 3 put: 13. matrix23 atColumn: 2 atRow: 1 put: 21. matrix23 atColumn: 2 atRow: 2 put: 22. ^ matrix23 atColumn: 2 atRow: 3 put: 23 I always thought that math notation was x,y (row,colum) How is it done in other languages? I checked the implementation so I know but why this choice in the API.

Proposal for LiteralArray class
by Ben Coman Feb. 17, 2015

Feb. 17, 2015

Looking into Image locking problems [1] caused by a recursive array such as this... literalArray := #( 1 2 3 ). literalArray at: 3 put: literalArray. I find that "literalArray printString" locks the image due to Array>>printOn: use of the recursive #shouldBePrintedAsLiteral method. Now its implementation is identical to #isLiteral and indeed "literalArray isLiteral" also locks the Image. So comparing implementors of #isLiteral... Object>>isLiteral ^false Boolean>>isLiteral ^true Character>>isLiteral ^true Integer>>isLiteral ^true String>>isLiteral ^true UndefinedObject>>isLiteral ^true ByteArray>>isLiteral ^self class == ByteArray Float>>isLiteral ^self isFinite "^(self - self) = 0.0" ScaledDecimal>>isLiteral ^denominator = 1 or: [(10 raisedTo: scale)\\denominator = 0] Array>>isLiteral ^self class == Array and: [self allSatisfy: [:each | each isLiteral]] ...I find most are very basic (might even say deterministic), with the recursion of Array>>isLiteral seeming an annomaly. Also, the big IF condition in Array>>printOn: smells like a design decision being made at runtime (Valloud AMCOS p12). Array>>printOn: aStream self shouldBePrintedAsLiteral ifTrue: [self printAsLiteralFormOn: aStream. ^ self]. self isSelfEvaluating ifTrue: [self printAsSelfEvaluatingFormOn: aStream. ^ self]. super printOn: aStream Flipping between two printString formats seems like selecting between two class types. Indeed, if we had a LiteralArray class, there would be no need for its printOn: to recursively search to determine its form, thus allowing #printStringLimitedTo: to do its thing to protect against infinite recursion. Also, instead of a recursive Array>>isLiteral we'd have something like LiteralArray>>isLiteral ^true Array>>isLiteral ^false which seems to align much better with the pattern of the other #isLiteral implementors. I notice there is both RBArrayNode and RBLiteralArrayNode. So what are the wider concerns that might apply? (In particular, I'm not sure how the #isSelfEvaluating (which is also recursive) fits into the big picture) cheers -ben [1] https://www.mail-archive.com/pharo-dev@lists.pharo.org/msg25156.html

GT / Debugger Inspector Duplication
by Sean P. DeNigris Feb. 17, 2015

Feb. 17, 2015

Right now, for the Debugger one must describe an object-specific inspector using EyeInspector, and then again with GT for the Playground. Can these tools be unified and build themselvs using the same declarative code? ----- Cheers, Sean -- View this message in context: http://forum.world.st/GT-Debugger-Inspector-Duplication-tp4806064.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

What is a Behavior, are Traits behavior too?
by Nicolai Hess Feb. 16, 2015

Feb. 16, 2015

I thought, Behaviors define the "behavior" of objects, therefore: Integer is a behavior, because it defines the behavior of "integer objects" Integer class is a behavior because it defines the behavior of the object "Integer". 5 isBehavior -> false. Integer isBehavior -> true. Integer class isBehavior -> true. What about Traits? Traits are "behavioral(?)", but they don't define the behavior alone, only the composition of Traits in an actual class defines the behavior of an Object. TClass isBehavior -> false. So far so good. Smalltalk globals allBehaviors includes:TClass -> true ! No suprise, because #allBehaviors explicitly collect all classes and traits. But the question is, what do we want to call a "Behavior"? All Classes and MetaClasses (-> Behavior allSubclasses) All Classes and Traits All Classes and Traits and MetaClasses and ClassTraits All Classes and MetaClasses and some Traits? (this of course, is related to http://forum.world.st/RBEnvironments-allClasses-Traits-Meta-tp4796370.html) In squeak Traits are behavior too. nicolai
