Which Smalltalk to use for production ?
by Squeak Smalltalk 25 Oct '04

25 Oct '04

Hi, I like Squeak. Is there anyone on the list that use squeak in a "real" product ? Or should I use VW or dolphin for our new development ? Best Regards W.

Translation: notes and enhancements
by azazel 25 Oct '04

25 Oct '04

Hello squeakers! I'm in the process of translating squeak messages to italian and i would like to share my impressions about translations tools and facilities: - first of all, thanks guys! The english only language was really a showstopper for the adoption of squeak as a tool in children's schools. Now a friend of mine want to try it out in her classroom :-) if italian language is available so that's why i'm translating it only now. - second the Language Tool does a great job, even if i would appreciate a more keyboard friendly navigation of the ui, but really i've still to find how to let the focus ignore mouse pointer position, but without success. Also, the PluggableList "resets" their scrolling if I, for example, translate a sentence that's in the middle of the catalog. I also tried to edit the saved file with the great emacs, but without success due to the fact that the stream that really contanins some undred of strings contains also some control characters ( i've still to check what's the marshalling tecnique used) - I know how to translate but not how to packetize my product and publish it on SqueakMap, so it would be helpful for translators to have an help section that explains how to do that thing. If you will answer that question here I will try to add it to the tools and send my changes to the authors. - I have spent also some hours trying to add a new feature to the tool but unfortunately without success, but let me explain. It will take some time to translate all the strings in the image ( the counter says that it knows about 850 string for now, and I've translated one undred of them) so it would be nice to have the ability to translate first the most used things like supplies, world menu, ecc....With that in mind, i've tried to add ad a functionality which use case is: - the user press a button or a key combination activating the facility; - the hand changes the shape to note that activation; - the user which has the windows he needs to translate opened, clicks on the windows ui; - if the morph under the hand is a StringMorph, intercept the event and open up the translation FillInTheBlank with string's text in the query; - save the translation upon confirmation; I've spent most of the hours on two things: trying to undersand all the translation code and look for examples of "hand events hooking" examples. For the first thing i've clearead my troubles, for the second thing i've still to find anything useful, Am I thinking it the wrong way? Have a good day Alberto -- Alberto Berti <alberto(a)metapensiero.it>

Class comments!?
by goran.krampe＠bluefish.se 25 Oct '04

25 Oct '04

Hi all! Please tell me something went hideously wrong when all the Multilingual classes went in? I mean - a quick look shows that only Locale has a class comment! So that is about 80 (!!) classes without class comments. I mean, sure, some of these can have short comments - but is it just me getting ANNOYED when there is NO COMMENT AT ALL?! IMHO this is NOT the way to increase quality. Don't get me wrong - I love this stuff getting in and I love and appreciate the work behind it. I still think that classes without class comments AREN'T COMPLETE and that if we never bother to set the standard higher it will NEVER get better. And sure, I also have uncommented classes in my packages - but they aren't in Basic. regards, Göran

3.7Full, class side initialization and IRCe
by Frank Caggiano 25 Oct '04

25 Oct '04

IRCe uses class side initialization to set up its directory structure. Because its class side initializations aren't done when someone loads a image with IRCe already installed (as with 3.7Full) a walkback occurs on IRCe startup. The current version on SqueakMap (10.2) addresses this problem. Basically it checks for the correct directory structure each time it starts up and creates it if it is missing. (Probably a good thing to do in any case.) If there is no way to get the fixed version into 3.7Full what would be the best way to warn new users and advise them to get the latest version from SqueakMap? regards -------------- Frank Caggiano frank at crystal-objects dot com http://www.crystal-objects.com The best educaion for the best is the best education for all.

Tabbed text morphs
by Brian Tabone 25 Oct '04

25 Oct '04

A nice feature to have for data entry forms is tabbing between entry fields. I did some cursory searching for tabbing support from text morph to text morph, but haven't found anything. My thoughts are to subclass the TextMorph class and add an overridden keyStroke method that would trap a tab key entry and lookup the next TextMorph in the display list and set the focus to that TextMorph. Before I go through the trouble and possibly duplicate someones efforts, I wanted to know if anyone might know of a way to do this. Perhaps I'm missing something in Morphic that supports this sort of thing. -Thanks, Brian T

Odd... Squeak born at OOPSLA BOF?
by Andreas Raab 25 Oct '04

25 Oct '04

Or so it claims at: http://www.oopsla.org/2004/ShowEvent.do?id=flash_bof "Birds-of-a-Feathers, or better BoFs have been a long standing tradition at OOPSLA. Quite a number of new products and ideas have been born, nurtured and raised at BoFs (e.g. Eclipse, Squeak). So this year we are going to put BoFs more in the spotlight! Meet the FlashBoF." But anyway, do we have plans for a BOF? Cheers, - Andreas

critical GOODS client bug fixes
by Avi Bryant 24 Oct '04

24 Oct '04

The problem below has been fixed, and a new version (78) is up on SM. I strongly recommend people upgrade to this - as well as fixing the decoding of negative small ints (would you believe this has never worked properly until now, and nobody noticed? Scary...), it catches a couple of edge cases where, after the right combination of conflicts and rollbacks, some changes were getting missed during commit.

OOPSLA sidetrip to Lee Valley store?
by Tim Rowledge 24 Oct '04

24 Oct '04

I know that a few other likely OOPSLA attendees are woodworkers and it struck me that a side trip to the Lee Valley <tools and other woodworker's objects of lust> store might be fun. It's a few miles from the con. so sharing a ride would be smart. tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Use GOTOs only to implement a fundamental structure.
