GC catcher
by Bruno Luca 01 Jun '06

01 Jun '06

Hello, i was looking at various method and classes but i didn't find anything interesting about this question. Is there a way to catch GC when deleting an object? Something like a method calling before deleting it... Byte. -- www.lethalman.net - Thoughts about computer technologies

Ajax + squeak = collaborative desktops ?
by Samir Saidani 01 Jun '06

01 Jun '06

Hi there ! Since I discovered this website (www.netvibes.com), I found that the technology used (ajax) is really interesting : we are using this website as a shared virtual desktop and it's amazingly efficient. It opens a new dimension for collaborative works as it was the case for wikis. (just use it and you will see ! Moreover I realized the importance of RSS feed throught this kind of site). Does someone know if such a techno is available for squeak (maybe seaside ?). I'm especially interested in the "post-it" feature we are using intensively. With netvibes, you have just to drag and drop a post-it on the desk and write on it, all is saved on the fly (no more "save" button as it is the case for wikis). I find this simple feature really cool ! Thanks ! Samir

[Squeak3.9b-7033 bug] 'SMSqueakMap bootStrap' doit fails with primitive failure
by Ken G. Brown 01 Jun '06

01 Jun '06

This still occurs in Squeak3.9b-7033. Refer to: <http://bugs.impara.de/view.php?id=3706> Installed ftp://ftp.squeak.org/3.9Beta/Squeak3.9b-7033.zip [^] running on VM Squeak 3.8.12beta4U.app on Mac G5 with OS X 10.4.6. Open a workspace, then execute 'SMSqueakMap bootStrap' After some time "Upgrading SqueakMap", get a primitive failed error. This is with no sm or package-cache folders present when Squeak starts up. Also occurs after first attempt when the two directories are already created. This failure also happens when first trying to Open SqueakMap and it requires an upgrade to a later version of SqueakMap to match the server. Therefore Cannot use SqueakMap at all. Is anyone else seeing this? Ken G. Brown

Squeak 3.9 image
by Lethalman 01 Jun '06

01 Jun '06

Hello, can i ask what happened to Shout in class browser and other tools? I can see only pretty print which i think is not as amazing as shout is in 3.8 (even if it's really Shout what i'm talking about). Is there a possibility to have Shout in 3.9, or whatever needs to be installed to get a syntax highlighting working? Bye.

Please distribute widely ESUG is proud to announce the Summertalk 2006 http://www.esug.org/promotionactions/summertalk2006/ Stef and Serge Stinckwich (on the behalf of ESUG) Here is a description This program is here to help students work on open-source Smalltalk projects. The European Smalltalk User Group (http://www.esug.org/) will fund 5 students during the summer. Each of student supporting organization or student will receive 1500 euros. Each student will work under the guidance of a mentor accredited by ESUG. The money will be distributed in 3 steps: start, middle and end of the project. The selection process done by ESUG will take into account whether the student will be supervised, if there is an infrastructure to help him as well as a the relevance of the topic for the community and the trust in the mentor. The code developed during this program has to be released under the MIT Licence. When and Process Running from from June 15th, 2006 through September 15th, 2005. By 10 of June ESUG should have received project proposals following the template: Name of the student : Mentor : Description of the work : Benefits for the community : Send an email to the ESUG board : stephane.ducasse(a)free.fr and Serge.Stinckwich(a)info.unicaen.fr with [SummerTalk-Proposal] Students: - If you are a student, just apply for the program by sending an email to the ESUG Board : stephane.ducasse(a)free.fr and Serge.Stinckwich(a)info.unicaen.fr with [SummerTalk-Student] and contact the mentor of the project. Sponsoring: - If you are a company and would like to help sponsor this event, send an email to the ESUG Board : stephane.ducasse(a)free.fr and Serge.Stinckwich(a)info.unicaen.fr with [SummerTalk-Sponsor] Go Smalltalk http://www.esug.org/

Namespaces code for 3.9
by goran＠krampe.se 01 Jun '06

01 Jun '06

Hi people! All those interested in namespaces might want to know that I made my code work in 3.9: http://map.squeak.org/packagebyname/namespaces It needs people playing, reading, testing etc. It is very simple to use, test it by installing from SM and start playing like this: 1. Create Foo::One, Foo::Two, Bar::Two, Zoo::Three. Note the slightly different class template. These namespaces are totally independent of the class category. Print these: Namespace spaces Foo == (Smalltalk at: #Foo) (Foo at: #One) == Foo::One 2. Add a method in Zoo::Three that accesses "One". It should work fine and not ask any questions. It should accept and render as only "One" even though the fully qualified name is "Foo::One". So as long as you have short names (without the prefix) that are still unique in your image you should not need to write or read the prefix. 3. Then create a method in Zoo::Three that mentions "Two" - you should get a question about which one you mean and it should auto expand to the fully qualified (=prefixed) name. Also, if you type "Two" in a workspace - you should get a question. 4. Add a method in Foo::One that references "Two". It should not ask, because the default policy is that references to "local" names (names existing in the same namespace as the class you are writing methods in) resolve to the local name, even if there are other "Two"s in the image. But this is just a tools thing - we could even have a Preference about this. 5. Also PLEASE READ class comments of Namespace and LookupContext! All tools should hopefully work fine with this code and if you don't use Namespaces this code should NOT affect you (but if it does in some way that is probably a bug) and the only problems I am aware of (off the top of my head) are: - Empty Namespaces are not currently removed automatically. You need to do it manually (as the class comment describes). - Browsing code is a bit slower because the browser needs to parse the code to "render" it with short names. If we use Shout more and more this could be included in Shout which I think is quite fast. - The versions browser (versions of methods) and probably a few other like a changes list etc - typically the tools showing code that is not compiled - do not do the rendering bit and thus always shows fully qualified names. - A few things should be turned into Preferences I guess. Like if the class template should be just like before, if short local names resolve without questions etc. I am writing a meticulous description of this code and will publish that as an article later on - but typically not until late june. But IMHO the code is easy (and relatively small) to understand. I have written about it in the past, like here for example: http://swiki.krampe.se/gohu/32 regards, Göran

Setting Up a Server to Handle Squeak Projects
by Dan Shafer 01 Jun '06

01 Jun '06

OK, I downloaded the Squeak plug-in and I seem to be able to access .pr files stored on other sites. But how do I deploy a Squeak project as a plugin? I think the questions I need answered are: 1. What does the server (Apache) need to know in order to serve Squeak projects as files? Anything? 2. Will detection of the plugin be semi-automatic? I.e., if a user without the plugin tries to download a Squeak project, will he get an error, an ugly binary dump or something meaningful? 3. Anything else I need to know about deployment? Thanks. Dan
