De Cleene 2008-05-17T10:35:12 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4320 Is there an easy way in Squeak to override a method? I have created a subclass of a class, and am viewing my subclass in a hierarchy browser. I have clicked on the superclass in the browser and am browsing methods to see what I need to override. Having discovered a method that I want to override - I was hoping I could right click on that method and select Refactor|Override - but its not there (it is in Dolphin). Failing this I tried drag and drop - but that seems to just move the method (I held the Control key while dragging but I guess thats a Dolphin and a windows thing). Is there some way to easily and quickly do this without having to cut and paste? Tim Tim M 2008-05-17T01:22:22 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4315 Newbie here, working my way through Guzdial's Squeak: Object-Oriented Design with Multimedia Applications (2001). One of the exercises requires building an Array with a block of code as an element, the idea is to lookup the stored block in some way and execute it. But, how do you store a block of code in an Array? For example, I can do this: [Transcript show: 'a message'] value But I can't get this to work: myArray := #([Transcript show: 'a message']). (myArray at: 1) value The reason is that (myArray at: 1) doesn't recognize the stored object as a block. Inspecting it shows the odd symbol: #[ ?? Can someone get me back on the clue train? Thanks, David David Finlayson 2008-05-16T19:11:50 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4314 Hi folks, Several people have complained about being confused when the hands-on examples don't work as described in various images. We have attempted to address this problem by providing our own dedicated image, available from SqueakByExample.org. This image has been specially prepared by Damien Cassou, and is a slight variant of the final 3.9 squeak-dev image. (Most of) the figures and exercises have been adapted so they really should work exactly as described in the latest revision (2008-05-15). We would be happy for feedback in case any further errors are found. (Please use the discussion list mentioned on the book's web site.) Thanks to one and all for the very positive feedback so far, and your patience with errors and oversights.

I think its possibly that the helpful prompt to create a class didn't put it in the change log? does this sound correct and is it a bug? This was in the Seaside one-click install image. Tim M 2008-05-13T23:39:24 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4301 Is there an easy way to define methods when you reference them in a new method? e.g. renderContentOn: html html heading: 'ToDo-List'. html div class: 'menu'; with: self menuComponent. When I save it warns me that menuComponent isn't defined but there is no option to define a stub method for it? So I simply select that its correct. Then in the new method there is no refactor operation to implement that method (in Dolphin I can select the AutoCorrect menu and there is a define method option - is there some addin for Squeak that does this? Or does everyone rely on having a test that calls the method and so you let the debugger define it?) Tim Tim M 2008-05-13T23:35:34 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4300 Has anyone purchased the Introduction to Seaside book available at Lulu? http://www.lulu.com/content/2234565 I've already gone through most of the on-line tutorial at http://www.swa.hpi.uni-potsdam.de/seaside/tutorial/ so I was wondering what additional material the book offered. I would be willing to purchase the book, if it offered substantially more than what the on-line tutorial covers, but on my student budget ... Paul ina tube 2008-05-13T20:36:08 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4299 Hello everyone, is there some documentation/tutorial somewhere which explains how to build a standard GUI application in Squeak? Cheers, Claus Claus Kick 2008-05-13T19:23:45 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4296 Hi Guys - I'm new to Squeak (but not Smalltalk) - I've fired up Squeak images over the years and been put off by the sheer noise in the user interface - but then I discovered Damion's dev image and it looked a bit more approachable - so I'm trying to get started. I've been trying the seaside tutorial to get going, and one thing that I have noticed is that when I right click (I'm using windows) I get a menu and it has items that have suffixes like "do it (d)" "pretty print (r)". What do the items in brackets mean? I thought they were some sort of keyboard shortcut but I can't seem to work out how I invoke them - in particular I was interested in how to quickly reformat my code when pasting in examples from the tuturial?

De Cleene 2008-05-12T10:08:43 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4294 First, I ask you read http://tech.groups.yahoo.com/group/squeak/message/127265 Ralph is not with us for a time and you must face my mistakes. Any good in the release come from he and the super crow behind the scenes working so hard. All troubles and mistakes from me. How you learn to build a release ? So I could be on Squeak IRC channel at random times, probability grow 7.30 to 10.30 Argentina time (10.30 GMT or you local time). I'm very serious but do jokes and speak in Spanish with all Spanish speaking people on IRC, so you are warned. We have here in Rosario, Argentina a "bar" or "café" group named SqueakRos , all people of any countries are welcomed. All kind of subject was talked , off course the most often is Squeak. For me, Squeak is more as exchange code, is a cultural experience. So I talk about life here in Rosario, Fútbol, Formula One, Sci Fi, Movies, Music, etc in IRC. I'm here to help , but you should read the book and the swiki before. 3.10 is just released, quick fixes is on the way 3.11 is on draft but soon we start. So , is your turn to complains direct to me. And if I can't find a solution you should send a letter to the Board so they fire me. Nos encontramos en el IRC :=) Edgar Edgar J. De Cleene 2008-05-11T11:16:11 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4293 Formal part and in Ralph absentia.... This release (3.10) is the first release on the road to smaller, more compact releases of Squeak. The Packages that have been removed are: * Flash * StarSqueak * SmaCC * Speech * Movies * FixUnderscores * OB * OmniBrowser The Universes browser written by Lex Spoon has been added to this release; this makes it much easier to install packages. Many actively developed packages are easily installable using this browser. For older packages that are not yet available from the Universes browser, SqueakMap is still available in the image to install these packages. Packages can also be installed directly from code repositories such as http://www.squeaksource.com/ using the Monticello browser. For example, Keith Hodges' Installer package is available from http://www.squeaksource.com/Installer, and the Universes package is available from http://www.squeaksource.com/universes. Quality control ------------------------------- We know that this release is not yet perfect, but there are now more than 2200 automated tests that run under Mac OS X, Windows XP and SimplyMepis Linux 6.5 every time a [BUG] or [ENH] report from Mantis is made to our update stream. Mantis ------------------- From now on, bug reports and improvements are best reported by filling in a Mantis report at http://bugs.squeak.org.

De Cleene 2008-05-11T10:46:09 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4287 When I first got Squeak last night I took a quick look at it and was quite impressed--thought it had a lot of potential not only for the project I currently want to do, but I could see possibilities for quite a few others as well. So this morning I got a copy of 'Squeak by Example', skimmed over the 'hello' and 'add two plus two' sections and started in on the first simple program 'Quinto'. Yeeeeks!! Nothing--absolutely <nothing.> --- works the way the author describes it. I did get a few things to work, but I had to piddle around (click on this, click on that) to get it done.

Serge Stinckwich 2008-05-07T06:33:10 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4273 Hi, More than a few times now I have played around with squeak. I keep leaving and recently I have realized why: I find it easier to follow code with in files than with a code browser. I can scroll a file fast and even I have 10 files open I still find it easer. So my question is: what is the best way to follow and reference multiple classes in multiple packages? I know I could open more than one class browsers but that seems cumbersome. gruntfuttuck 2008-05-03T12:46:31 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4269 When writing to Transcript using Transcript show:, after certain amount is put on the Transcript, the screen gets cleaned, keeping only about 10K of text. Is there a way to increase the amount of text Transcript keeps before cleaning? Thanks Milan PS: I tried to inspect the Transcript model (TranscriptStream) and modify the readLimit and writeLimit but it did not help. Milan Zimmermann 2008-05-02T16:49:44 http://comments.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners/4268 Hi, I've been testing Squeak's ability to handle large amounts of data. This snippet: testArrayFilling | startTime endTime iArray jArray kArray | iArray := Array ofSize: 100. 1 to: 100 do: [:i | jArray := Array ofSize: 1000. 1 to: 1000 do: [:j | startTime := Time millisecondClockValue. kArray := Array ofSize: 1000. 1 to: 1000 do: [:k | kArray at: k put: Object new]. jArray at: j put: kArray. endTime := Time millisecondClockValue. Transcript cr; show: i asString , ',' , j asString , ' ' , (endTime - startTime) asFloat asString. startTime := Time millisecondClockValue]. iArray at: i put: jArray]. Transcript cr; show: 'Finished' creates about 5 million objects , then the image freezes. When I run on the same machine under Windows, it happily continues until the short of memory warning ( about 70 Million objects in my case). The VM is 3.7 in both cases, the image Damien's 3.9 development image. There seem to be a number of Unix lockup issues. Is a later (or earlier) VM likely to fix this please?

The code on page 33 for the Quinto game is returning an error message. I have the SBECell selected and "-- all --" is highlighted in the right pane, just like in the book, but it responds with the message "Unknown variable: initialize please correct or cancel: / declare temp / declare instance / cancel". So I guess it doesn't recognize "initialize" and thinks I'm trying to create a variable? According to the book it should be recognized. Here's the code: initialize super initialize. self label: ''. self borderWidth: 2. bounds := 0< at >0 corner: 16< at >16. offColor := Color paleYellow. onColor := Color paleBlue darker. self useSquareCorners. self turnOff I even downloaded the code for the book from Squeaksource and pasted it in and it does the same thing. Any help would be appreciated.
