BalloonEngine initialize. DataStream initialize. DeflateStream initialize. FastInflateStream initialize. ZipConstants initialize. ZipWriteStream initialize. PNGReadWriter initialize seems to solve it. -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] GUIs with Pharo / how to learn smalltalk
by Daniel Lyons March 25, 2011

March 25, 2011

Hi, I have two questions, a technical one and a more general one. In broad strokes, what are people doing for GUIs? My guess would be using Morphic, but googling around you find more abuse than use, it looks like, and very little live links to up-to-date documentation. It makes me wonder: is there something other than Morphic which is being used? Or is everyone doing web apps? Or is there some other GUI toolkit I haven't found yet, and that's where all the action is? Whenever I see a neat Morphic window or something, I feel a bit like there's a party going on somewhere and I didn't get an invitation. Like the first rule of Morphic club is you don't talk about Morphic club. The general question I have is basically, am I the problem? Is it that the documentation isn't where I expect to find it, or in the form I'm used to seeing, or that it isn't relevant somehow in the Smalltalk universe? Or is it all really intuitive except for me? :) I could accept that, I suppose, but how did you Smalltalk wizards become wizards? Did you just dive in and start reading the code in your own image? Was there some master Smalltalk wizard that you knew who showed you how to do these things? I'm currently reading Smalltalk Best Practice Patterns and it's one of the best programming books I've ever read. I see that there is a great deal of mastery of programming going around in Smalltalk circles, but I don't see the books that take you past beginner towards master, other than SBPP. So what's the trick going on here? How did you guys become excellent? I hope none of this comes across as negative; I think surely it's that I'm missing something. Thanks, â Daniel Lyons

[Pharo-project] What is the future of GUI in Pharo?
by nullPointer March 25, 2011

March 25, 2011

Many new things is happens this days on Pharo, and I donÂ´t understand the status of all. What is the future of GUI in Pharo? what changes will happen? which is the roadmap? Now I see SimpleMorphic. Pharo will work with it? Pharo will works with another way of draw/render the morphs? We will reduce the number of morph classes and hierarchy? The Morphic UI designer will be incorporated in dev image? Thanks for your answers. -- View this message in context: http://forum.world.st/What-is-the-future-of-GUI-in-Pharo-tp3400855p3400855.… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] [ANN] Self-learning PocketCube Solver
by HwaJong Oh March 25, 2011

March 25, 2011

Hi, I am working on PocketCube solver (project wiki page here: http://appdal.com/groups/36442/wiki/80aad/PocketCube_Solver_with_Pharo.html ) My latest version of this can generate classes that can recognize pattern of PocketCube. If there is a PocketCubePattern subclass that matches current PocketCube it gets used to solve it. If there is not, a new pattern subclass gets created on the fly, and continues to solve the PocketCube. Watch the demo video below. http://www.screencast.com/users/BaseballTeam/folders/Jing/media/d7db8f85-f8… Best Regards -- View this message in context: http://forum.world.st/ANN-Self-learning-PocketCube-Solver-tp3404815p3404815… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] positionalMesssge breaks literal array parsing
by Eliot Miranda March 25, 2011

March 25, 2011

Hi All, the following won't parse because of support for positional messages (whatever they are; I'll come to that later). #(word()) should be equal to { #word. #() } but because of the type == #leftParenthesis clause in the below it causes a syntax error: Scanner methods for multi-character scans xLetter "Form a word or keyword." | type | buffer reset. [(type := self typeTableAt: hereChar) == #xLetter or: [type == #xDigit or: [type == #xUnderscore and:[self allowUnderscoreSelectors]]]] whileTrue: ["open code step for speed" buffer nextPut: hereChar. hereChar := aheadChar. aheadChar := source atEnd ifTrue: [30 asCharacter "doit"] ifFalse: [source next]]. tokenType := (type == #colon or: [type == #xColon and: [aheadChar ~~ $=]]) ifTrue: [buffer nextPut: self step. "Allow any number of embedded colons in literal symbols" [(self typeTableAt: hereChar) == #xColon] whileTrue: [buffer nextPut: self step]. #keyword] ifFalse: [type == #leftParenthesis ifTrue: [buffer nextPut: self step; nextPut: $). #positionalMessage] ifFalse:[#word]]. token := buffer contents e.g. evaluate any of the following: #(word()) Compiler evaluate: '#(word())' Scanner new scanTokens: '#(word())' What is this support for? Is it for those funky ffi calls in the OpenGL code? Can it not be hoisted out of the scanner and into the parser proper? [and optimistically anyone have a fix already?] best, Eliot

[Pharo-project] custom code on squeaksource
by Camillo Bruni March 24, 2011

March 24, 2011

We are currently working on first-class slots and layouts in pharo. This required some changes in how the class definitions are printed: ============================================= Object subclass: #Layout layout: ObjectLayout slots: { #host => Slot. #compactClassIndex => Slot. } classSlots: {} globals: '' category: #'Slot-Layout' ============================================= I adapted the MCClassDefinition >> definitionString to output our new class definitions. However squeaksource is not too happy with this and rewrites it completely using the default definition. Local mcz files contain the new definition, mcz files loaded form squeaksources still the old definition. Is there a way to still use squeaksources with our custom classes? thanks v(^_^)v camillo
