Magma tutorial or examples
by ina tube 27 Nov '07

27 Nov '07

I recently loaded Magma into my image to play around with, following the Getting Started Guide at: http://wiki.squeak.org/squeak/2689 I looked around for some more documentation or code examples but was not able to find any. Can someone point me to sample programs that illustrate how Magma is used? Thanks, Paul PS: There may be a few errors or ommissions in the Getting Started guide. After creating the sample repository with, MagmaRepositoryController create: 'c:\myMagmaFolder' root: Dictionary new the guide explains that in single user mode, one can use the new obejct store by executing myMagmaSession := MagmaSession openLocal: 'c:\myMagmaFolder\myRepository.magma'. myMagmaSession connectAs: 'chris' I got a traceback when I tried the above. I got it working only after trying myMagmaSession := MagmaSession openLocal: 'c:\myMagmaFolder'. myMagmaSession connectAs: 'chris' Ie, the MagmaSession class>>openLocal: method takes a directory name rather than a particular '.magma' element. -- _______________________________________________ Get your free email from http://mail.doramail.com Powered by Outblaze

Regular expressions in Squeak?
by Thor Bergquist 25 Nov '07

25 Nov '07

I'm an experienced programmer, but Squeak novice. Can someone give me step-by-step instructions (for a novice) for how to find the best regex implementation for Squeak and how to install it.

Added Instance Variables and Methods are not shown in System Browser
by Warakorn Paphrawat 18 Nov '07

18 Nov '07

I developed a little Meta-Programming application, which adds methods to the MethodDictionary of a class and adds instance variables + getters/setters. However, after running this application the changes are not reflected in the System Browser. All new instance variables and new methods are not shown there. On the other side I can run a little test application, which creates a new instance of class (to which I added some methods and variables), which in turn uses some of the added methods and instance variables through getters/setters without any errors. Is there any trick to make these added methods and instance variables visible ? Again, the new methods are correctly integrated into the MethodDictionary with selectors and CompiledMethods according to "aClass inspect". Is there another way to check whether the new methods and new instance are really integrated into a new class? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

monticello package - adding instance variables to existing classes
by itsme213 18 Nov '07

18 Nov '07

I understand how Monticello deals with me adding (in my package) some methods to an existing class like Object (from other package). How does it deal with me adding an instance variable? Thanks!

Is there an update to flashmorphreader or possibly another way to support a flash file version greater than 3 (I have a few Flash version 5 files)? Best regards, Rich =============

variables declared in workspaces
by gruntfuttuck 15 Nov '07

15 Nov '07

Hi, I added this code to a workspace: oneMinBeeper := TaskScheduler new. oneMinBeeper do: [Beeper beep] every: 1 minute. oneMinBeeper start. I then deleated the the workspace thinking that it would take the oneMinBeeper object with it. Insacly one minute later I realized that's not how it works! How do I now access this object? How can I kill it. Also some general info where objects live would be useful. I notice that if I open up another workspace and inspect oneMinBeeper, that it's referred to an undefined object but it must be defined somewhare as it's still beeping.

tutorial: "doesNotUnderstand" instance variable
by Andrew n marshall 14 Nov '07

14 Nov '07

I'm trying to go through the pipsqueak tutorial, but it throws a doesNotUnderstand error when I try to initialize the exitSides instance variable the first time. The browser shows the exitSides variable (with nil value), so the VM knows its there. This is my class declaration: Object subclass: #BlankCell instanceVariableNames: 'activeSegments exitSides' classVariableNames: '' poolDictionaries: '' category: 'Laser-Game-Model' This is my init function: initializeExitSides self exitSides: Dictionary new. self exitSides at: #north put: #south. self exitSides at: #east put: #west. self exitSides at: #south put: #north. self exitSides at: #west put: #east. And a screen shot of my error stack trace is here: http://www.isi.edu/~amarshal/transfers/squeak_error.png (How do I copy it as text anyway?) Anm

BUG in XMLElement >> printXMLOn:
by Thomas Fischer 14 Nov '07

14 Nov '07

Hi list, when I do: Transcript show: (XMLDOMParser parseDocumentFrom: ( ReadStream on: '<xml>T1<E1/>T2<E2/></xml>' )) I get: ' <xml>T1T2 <E1></E1> <E2></E2></xml>' The order of child nodes is wrong: T1,T2,E1,E2 instead of T1,E1,T2,E2. I don't understand, why a XMLElement has TWO collections: contents elements instead of ONE collection for childNodes. salute Thomas -- View this message in context: http://www.nabble.com/BUG-in-XMLElement-%3E%3E-printXMLOn%3A-tf4806032.html… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

can't install Squeak on Ubuntu 7.10 -- could not find display driver vm-display-X11
by Bryan Berry 13 Nov '07

13 Nov '07

I have been trying to install Squeak on Ubuntu 7.10 w/out success I was able to install it w/ Debian packages but the sound didn't work. At the advice of my colleague Luke Gorrie I tried installing it from the VM-Source tarball http://ftp.squeak.org/3.9/unix-linux/Squeak-3.9-8.src.tar.gz I used the documentation in /unix/doc/HowToBuildFromSource.pdf I ran the configure script and got an error that it couldn't find npsqueak libraries. I then tried ../config/configure --without-npsqueak it configured but this showed up in the config.log configure:26825: result: ******** disabling vm-display-X11 I then did make and make install Predictably, I get this error when I try to open a squeak image $ squeak olenepal-demo.4.image could not find display driver vm-display-X11; either: - check that /usr/local/lib/squeak/3.9-8/vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted (core dumped) Please assist :) What's the best place to look for documentation on Squeak installation? I found some in the Squeak wiki, OLPC wiki, and a few other places but no single comprehensive resource. I will try to add notes on how to successfully install Squeak on Ubuntu 7.10 onto the OLPC Wiki once I can successfully install it myself : Help! Part of my job is to teach people how to use Squeak so our development team (the real programmers) can focus full-time on developing learning activities w/ Squeak. I need to get up to speed on Squeak quickly. Thanks -- Bryan W. Berry External Relations Manager OLE Nepal, http://nepal.ole.org
