[Pharo-project] Pharo 1.4 & CogVM
by recursive68＠gmail.com April 19, 2012

April 19, 2012

Hi, I've just downloaded the latest Pharo 1.4 image and separate CogVM from the pharo download page. When I use the File Browser and attempt to select/enter a directory containing many files the image freezes up and I can't get it to respond. The interrupt "CMD-." does work and brings up: UnixStore(DiskStore) directoryAt: aPath ifAbsent: absentBlock nodesDo: aBlock | encodedPathString index entry pathString | index := 1. pathString := self stringFromPath: aPath. encodedPathString := Primitives encode: pathString. entry := Primitives lookupEntryIn: encodedPathString index: index. entry = #badDirectoryPath ifTrue: [ ^ absentBlock value ]. [ entry isNil ] whileFalse: [ entry at: 1 put: (Primitives decode: entry first). aBlock value: entry. index := index + 1. entry := Primitives lookupEntryIn: encodedPathString index: index ]. ^ self Presumably it's a bug ? This is on OSX 10.7.3. Thanks

[Pharo-project] Problem with Traits, Ring, RPcakage and Obsoletes
by Mariano Martinez Peck April 18, 2012

April 18, 2012

Hi guys. I am running some tests with Fuel. In such test I create classes and traits. The problem is that I get a: "MessageNotUnderstood: receiver of "isProvided" is nil" Everything starts (it seems) when I do #addToComposition: and I receive a MethodRecategorized event and RPackage calls #systemMethodRecategorizedActionFrom: There, the problem is with -> method isProvidedByATrait the class of the method is 'AnObsoleteClassForTestToBeDeleted1' And the error finally arrives to #providedLocatedMethod where it does "each method isProvided" the problem is that "each" is a RGMethodDefinition with everything in nil except 'name' and 'annotations'. I attach PharoDebug.log. Any help is really appreaciated. Thanks, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] gamedev.net post asking about Smalltalk
by askoh April 18, 2012

April 18, 2012

Some is interested in using Smalltalk for prototyping of games. http://www.gamedev.net/topic/623380-game-programming-in-smalltalk/ I think we should respond very constructively on gamedev.net to entice gamers to try Smalltalk. Programmers are coming to appreciate dynamic languages and we can capitalize on that.

[Pharo-project] Debugger code edits lost?
by Schwab,Wilhelm K April 18, 2012

April 18, 2012

Please do not ask me how to reproduce this... :) Actually, I *think* it might be triggered by certain types of syntax errors. Bottom line is that the sometime I do a fair bit of coding in the debugger, only to find that the fruits of my labor went to oblivion and beyond. Gone - no trace of it. It has happened enough that that I believe there are legs to it. Has anyone else seen it?

[Pharo-project] Good news / bad news
by Schwab,Wilhelm K April 18, 2012

April 18, 2012

The attached represents success (I think/hope<g>) with getting GSL to fit a Gaussian plus a line to some data. I hope to use this to measure widths of peaks in FFTs of specific signals. The bad news is that I can't get Alien callbacks to work. Actually, the callbacks seem to work just fine, but I get "invalid number of arguments" and other errors as the function that calls the callbacks is either finishing up, close to that, or returns. FWIW, that call is made via FFI. The nature of the problem is not clear, and I lack the vm skill to reasonably think I could debug it. Using C functions to define the residuals and jacobians works perfectly, so I am on the (presumptuous) edge of thinking that my code is not the problem. Any ideas? Bill

We will fix those... we tried to get the tests to be run by jenkins on windows for 1.4, but then decided to postpone it this week. (It's nearly working... but not completely. And then making the tests green is another story...) Marcus -- Marcus Denker -- http://marcusdenker.de
