Does it matter? I don't think we bothered to implement the last ANSI standard fully. :-) On Nov 13, 2007, at 5:43 AM, stéphane ducasse wrote: > who wants to sponsor me? > I'm sorry but I do not have 1200 USD to be able to participate. > > Stef > > On 13 nov. 07, at 10:50, Bruce Badger wrote: > >> Fellow Smalltalkers, >> >> (this is a one-off to every Smalltalk list I can think of.

Oddly bound variables in compiled methods...
by Alejandro Fernandez 14 Nov '07

14 Nov '07

Hi, after a while trying to chase down a bug, I found out that a method that was apparently referring to an instance variable, was bound to a different one. Let me clarify: I had a Person class with variables name and email. I had a setter method for name that correctly tried to assign (underscore assignment, in case that makes a difference) to the instance variable name. However, after the method executed, named remained nil, and the method argument had been assigned to email. I modified the setter (simply adding a space), saved it, and it started working well. Is that a common problem? How do I avoid it? I am using squeak 3.9 with a seaside-ready image sq3.9-7067web07.08.1.zip I got somewhere.

ANSI Smalltalk
by Bruce Badger 13 Nov '07

13 Nov '07

Fellow Smalltalkers, (this is a one-off to every Smalltalk list I can think of. Sorry for the Spam-esqe nature of this) Work is under way to get the Smalltalk ANSI standardization process restarted. This is intended to be an on-going process which delivers a new version of the standard every 18 months to 2 years. The participation of all Smalltalkers is invited. The ANSI standard should be driven by the people who use Smalltalk as well as people who develop Smalltalk environments. Work on the standard will all happen through a mailing list: http://lists.openskills.org/cgi-bin/mailman/listinfo/ansi-smalltalk The list archive is open and anyone may join the list. The only up front requirement being that you give your full name when signing up so everyone knows who is who. While anyone can get involved in discussion and informal votes, only people who are registered with the ANSI project may formally vote. Registration in this context means joining INCITS (the organization which coordinates IT ANSI standards work), and that costs $1,200 USD. Already we have the Smalltalk vendor companies getting involved. We also need people representing the user community. If you work in a company that uses Smalltalk please raise this ANSI work at your next team meeting and see if you can have someone (or more than one) from your project join the ANSI Smalltalk mailing list. Perhaps your company could fund the $1,200 to have someone be a voting member of the committee too. If you wish to discuss the ANSI project please either join the mailing list or post a message to comp.lang.smalltalk. The news group is the cross-dialect discussion forum for Smalltalk and the ANSI standard is most certainly cross-dialect.

how to make it apparent that a TextMorph's text (or substring thereof) has been selected?
by Alexandre Rousseau 13 Nov '07

13 Nov '07

Hi I am working with a descendant of TextMorph. The following code does what I want except for one thing: make it apparent that there is a selection, i.e., no selection highlight is visible. mouseEnter: evt self takeKeyboardFocus. self editor selectAll. Can someone point me in the right direction? Thanks in advance Alex == Alexandre Rousseau E: alexr(a)mailsnare.net NinerPaint: http://www.ninerpaint.com flickr: http://www.flickr.com/photos/80052761@N00/

comeToFront
by Jerome Peace 13 Nov '07

comeToFront Hi Trygve and Karl, This would be a good issue to make a mantis report. It's clearly something that needs to be tracked. I've looked at the system window internals. I bet that some serious study will need to be made before a stable repair can be made. So a mantis report would be a good place to collect analysis and repair attempts. It would also be good to have a user story. What would be a simple description of the way it should behave? Hth, Yours in curiosity and service, --Jerome Peace *** >Trygve Reenskaug trygver at ifi.uio.no >Mon Nov 12 17:34:57 UTC 2007 > > >Thanks Karl.
