RE: [ANN] UI Enahncements released

This error seems not to be caused by your changes but by something in the Omnibrowser panes. I have before fixed this error in the old browser but it seems Omnibrowser has some other widget than the regular browser... I observed the error on a older version of Damiens 3.10 dev images and I'll see if I can track it down:-) Karl <http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-September/date.…> <http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-September/autho…> > Could you be more specific.

Sport 3 000
by Bruce Badger 07 Sep '07

07 Sep '07

The current version of Sport for VW is now 3 000 and it is available from the Cincom public Store. This version has been released primarily to clearly indicate the most recent of the main-line of the Sport implementation in VW. For those of you who have been following the main line of the VW implementation version 3 000 makes no API or behaviour changes. Janko and I are currently discussing how to merge in his work which has taken place over the last several months and which is a branch from quite an old version. All the best, Bruce -- Make the most of your skills - with OpenSkills http://www.openskills.org/

[Help] How can I fileout to an internal stream?
by Jerome Peace 07 Sep '07

07 Sep '07

How can I fileout to an internal stream? Ok. Ive run into a problem in 3dot10. When writing out text in a Sans Vera font it reads back in Accuny. That is, save the text morph and read it back. Now Id like to write a test for this w/o actually having to write a file to disk. All I need is to put an object into a stream encoded as if for saving and then read it back decoded from the same stream. Whats the best way to do that? Ive chased methods till my eyes hurt and would like help, hopefully from someone who already knows the answer. Yours in curiosity and service, --Jerome Peace ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC

Sport 2.031 with image startup/shutdown support
by Janko Mivšek 07 Sep '07

07 Sep '07

Dear Smaltalkers, I published a new Sport portability library which has now a portable support for image startup and shutdown tasks. This is useful for any cleanup you want to o before image is quit and for any work after image is started. For instance, a Swazoo web server will restart all its websites automatically after image start with help of those Sport startup methods. See class SpEnvironment, class methods in 'image startup/shutdown' Usage example: - SpEnvironment addImageStartupTask: [anObject restart] for: anObject - SpEnvironment addImageShutdownTask: [anObject stop] for: anObject You can find it on SqueakSource and Cincom public repository for VW. Best regards Janko -- Janko Mivšek AIDA/Web Smalltalk Web Application Server http://www.aidaweb.si

DeltaStreams moving forward
by Göran Krampe 06 Sep '07

06 Sep '07

Hi folks! A quick report from the DeltaStreams project. I and Matthew Fulmer have been cranking out code in a decent speed actually and stuff is starting to work for real. We are currently implementing DSDelta, DSChange (with 24 subclasses, each representing a particular kind of change) and DSSystemEditorApplier which is the visitor that actually can apply (make the actual changes) a DSDelta to the image. A DSDelta currently listens to SystemChangeNotifier just like ChangeSet does and captures all (I think) possible kinds of changes in an OrderedCollection. Each change instance can answer with its antiChange and a DSDelta can produce its own antiDelta by responding to asAntiDelta. DSDelta implements #revert basically as "self asAntiDelta apply" and the actual "apply" is done using a simple double dispatch visiting scheme. The current code uses SystemEditor from Colin Putney - we have made several bug fixes to it and I think our current test failures seems to be rooted in SystemEditor. Currently we have 81 tests, 66 passes with 11 failures, these include a bunch of revert-tests. Matthew just recently started thinking about implementing a tool UI on top - a la change sorter and we are targeting ToolBuilder - if anyone has views on that we are all ears. Our prime targets for this project are 3.7-3.10 + Croquet. Serialization formats, DSDelta normalization, DSDelta analysis (conflict detection, analysis on how/if it can be applied properly to the image etc) and transport (streams) have not been started yet. regards, Göran

Thesis - Implementing the Smalltalk Collection Hierarchy usings traits
by claudio acciaresi 06 Sep '07

06 Sep '07

Hello, we (Nicolas Butarelli and Claudio Acciaresi ) are from Buenos Aires , Argentina , were going to implement a new (we are not going to refactor the hierarchy, we are going to implement the hierarchy from scratch) Smalltalk Collection ((our idea is to be complaint with the ANSI Smalltalk Collection protocol) Hierarchy using Traits. We would like to know if someone can tell us, how to set up a Trait browser, because we have been trying to use different version, but none of them work fine. Does anyone know the exact package and squeak version, that we need to use a Trait browser? Any opinion on this idea will also be useful, if you have comments, please tell us. Thanks a lot.

Yes, you 're right, actually that is what we are doing now, but it would be very useful for us to be able to use the traits browsers.

You don't need a Traits-aware browser to use traits. The can be used and modified just fine from a normal browser.
