Hi all, I thought I'd send out a reminder about the Squeak Foundation Board Elections. If you would like to vote in the upcoming Squeak Foundation Elections, you should check your email address on Squeak People. http://people.squeakfoundation.org/ . Please make sure you have access to your squeak people account, check that you included your name and that the supplied email is correct. If you need help accessing your account please let me know. You will need access to the email supplied to receive a ballot. If you have not signed up for a squeak people account and you would like to vote in the election please sign up and then encourage people you know to certify you. Only Squeak People members that have a certification of Apprentice or higher have supplied a real name and a valid email will receive a ballot to vote in the election. This is only a reminder about Squeak People. We have not set the voting schedule. Please stay informed, get involved in the upcoming election and remember to please vote. Also I'd like to express our thanks to Ken Causey for helping us get the tools we needed to better run the election this year. Thanks Ken! Happy Squeaking, Ron Teitelbaum Squeak Elections Team Member

hi i'm a non programmer who wants to learn to program because i wanna make http://twext.cc/go/twexter work php has lots of developers and we have some existing php code to start with, but maybe squeak is better? * squeak sounds simpler * maybe easier to learn * maybe easier to work with * http://wiki.laptop.org/go/WiXi#scratch i got here because i saw an article i liked: http://onsmalltalk.com/programming/smalltalk/simple-image-based-persistence… which may be a way to avoid mysql mysql looks really really hard to me.. my dream is distribute/find/modify/share twext data in some kinda flexible machine readable and very *human* readable flat file system: http://twext.cc/go/18#.twx first things first, my basic question is this: would squeak be a good way to get text twext? DEMO: http://twext.cc/twexter CODE: http://twexter.svn.sourceforge.net/viewvc/twexter/twexter-basic/ if yes, is there anyone i can pay to help me get twext with squeak? thanks!!

Hi Jakub, if I correctly understand your question the following will do what you want: test := MyTest new. myString:= ('phone1' , ':' asString) asSymbol. test perform: myString with: 'tesValue'. The above you can use in a Workspace. The essential from this is: Object perform: with: MyTest contains: MyTest>>phone1: aValue phone1 := aValue. MyTest>>phone2: aValue phone2 := aValue. HTH Frank >hello i have class with two setters >phone1: aValue >phone2: aValue > >and i want call it dynamically >aSelector is phone1 or phone2 string > >setPhohne: aSelector by: aValue > >phoneBook perform aSelector, ':' aValue > >but this is not working how can i do this when i try this iwth getters it works fine > >Transcript show: (phoneBook perform aSelector); cr.

The Weekly Squeak Summary No. 16: Nov 11, 2007 - Jan 12, 2008
by Michael Haupt 14 Jan '08

14 Jan '08

Dear Squeakers, happy new year, and welcome to the The WeeklySqueakSummary, an irregular traffic-dependent report on what's going on in the world of Squeak based on the WeeklySqueak blog. Highlights of the past weeks: The one topic that has gotten most coverage on the Weekly Squeak blog recently has been the OLPC initiative. The enormous response to the G1G1 (give one, get one) programme [1] has shown that great interest in the little green boxes is prevalent also in non-target countries of the initiative [5,8]. Intel is no longer a member of the consortium [11], and one may wonder whether the "competitive products" will stand the comparison... [12] Lively is a very interesting JavaScript-based development environment running in your browser (if you use a very recent Firefox or Safari build, that is). It looks somewhat familiar to Squeak users. Dan Ingalls has given a presentation at Stanford [13]. FInally, there's a nice collection of images showing Smalltalk running on an Alto [9], taken in 1979, when Smalltalk was still very very young. (But hey! It's a GUI! In 1979!)

Squeak 3.9 VM on amd_64
by cnantais 11 Jan '08

11 Jan '08

What's the approach for getting the 3.9 VM running on Debian on amd_64 hardware? I used the Linux 32-bit binary of the VM and tried to run it with 'squeak -headless my.image' and, while a squeak process does appear in top, but I can't access WAKom/Seaside which should be running on port 8080.

Proxy objects
by cnantais 11 Jan '08

11 Jan '08

Can someone recommend a good read on how to use proxy objects in Smalltalk? I'm trying to verify expectations about the messages that classes are receiving (as is done in rSpec, the Ruby BDD framework) and I think proxy objects may be the right pattern. Thanks, Chad -- View this message in context: http://www.nabble.com/Proxy-objects-tp14746225p14746225.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

About installing magma
by Xinyu Liu 09 Jan '08

09 Jan '08

Hi, I tried to install Magma, failed many times and finally get it installed. So I want to share my experience with all new guys to Magma. I first try to installed it form Package universal browser as described in seaside tutorial[1], persistence chapter. The image I used is downloaded from Damien Cassou's link ( sq3.9-7067-web.08.01.1). When I selected "Magma tester 1.0 r40" from "Persistence" category and install it, I always got "download error". (both in windows and linux) Then I tried to evaluate the following lines from http://wiki.squeak.org/squeak/6021 Installer squeaksource project: 'Installer'; install: 'Installer-Core'. Installer universe answer:'username' with:'admin'; answer:'password' with:'seaside'; install: 'Magma seasideHelper'; install. But I got "VM crash" fatal error. I tried all kinds of methods including download the latest 3.10 VM and image from www.squeak.org. and all got same "VM crash" error. Finally I downloaded all the necessary Magma mcz files manually from http://www.squeaksource.com/Magma/ to my package-cache folder. there is a mcm file seems as monticello configuration. Then I open monticello and try to load the mcm, but get some bug, so I opened the mcm file manually, and installed the mcz files one by one as specified in that mcm file. This method finally got Magma installed and works ok. Best regards. Yours, -Xinyu -- [1]: http://www.swa.hpi.uni-potsdam.de/seaside/tutorial

ByteString>>match: greedyness of * ??
by Ch Lamprecht 08 Jan '08

08 Jan '08

Hello, I found the following results for some expressions using #match: 'e' match: 'e'. "true" '*' match: 'e'. "true" '#' match: 'e'. "true" '*e' match: 'e'. "true" '*#' match: 'e'. "false" '**' match: 'e'. "false" '*' match: ''. "true" '**' match: ''. "false" Is this expected behavior? Looks like * is sometimes 'greedy', sometimes not. (Comparing 4 and 5) Thank you for any hints. Christoph
