by David LeBlanc 26 Nov '98

26 Nov '98

Hi; I see a changes and an image file - neither compressed in the "2.3" dir. Not to be terminally obtuse, but do I just download those to my squeak dir or what? Thanks, Dave LeBlanc

Re: So, how do you stop execution

> So, how does one stop execution? FWIW, I'm on a mac. Thanks! Not really sure what you mean by "stop execution" (of what?) but you might try the Cmd-. (period) combination to interrupt Squeak at what it's doing at the moment.

FWIW, I'm on a mac. Thanks! Hi Bruce, You should be able to stop execution by pressing CMD-. (command & period). I forgot which is the command key on a Mac, but it should be the Apple key. Can anyone back me up on this one?

Wow! This is excellent! Is the Flash code derived from the freeware flash plugin for Netscape? It's been quite a week! Macromedia even released an official beta flash plugin for Linux too! :) > > I think that are the biggest changes in 2.3 beta [Dan - did I miss > anything important?!] > > Cheers, > Andreas > -- > Linear algebra is your friend - Trigonometry is your enemy. > +===== Andreas Raab ============= (raab(a)isg.cs.uni-magdeburg.de) =====+ > I Department of Simulation and Graphics Phone: +49 391 671 8065 I > I University of Magdeburg, Germany Fax: +49 391 671 1164 I > +=============< http://isgwww.cs.uni-magdeburg.de/~raab >=============+

Re: Squeak 2.3 beta available

2.3beta for Intel/Linux, Sparc/{Solaris,SunOS}, Alpha/DU4.0 are at: ftp://alix.inria.fr/pub/squeak/unix/2.3beta/ The image/changes files are not there, simply due to lack of space. I'll clear out some old stuff to make room for these files when 2.3proper arrives. For now, image/changes are at: ftp://st.cs.uiuc.edu/Smalltalk/Squeak/2.3/Squeak2.3beta.{changes,image} I've not tested these VMs, beyond launching the vanilla 2.3 image and totally failing to puzzle in the slightest any of the local sheep. In particular, I've not tried to use the new dynamic primitive stuff. Let me know if there are any problems. Enjoy. Ian

That's much better... to be honest, if any one of us 'non-Disney' porters and VM geeks deserves the 'his awesomness' appelation, it would be Ian Piumarta. The amount of work he did to write all the X stuff, I wouldn't use as a punishment detail! Doing the AcornLinux and then Itsy port was easy because of the work he did, and then the NetWinder port was mostly the hard work (for Craig) of getting it to talk to our net, get the files in the right place, choose the right config stuff and persuade a very-beta system to actually do what it is supposed to do. tim -- Always try to be modest.

Re: Squeak for embedded systems (remote debugging and image building)

The repackaging problem is the one that interests me the most. I have loosely fashioned my own approach with a nice ponderous title "Smaller than Thou talk." -- i.e. Sttt or St3 -- to keep the goal clear in my mind and add a little sense of competitiveness to the challenge. I have gotten a slightly "shrunk" PWS to work, and now starting to build a headless version, using Dan Ingalls's prior work in this direction. It seems somewhat distressing to me that the PWS works by executing Smalltalk expressions from the Squeaki-Wiki pages, as that means that I could not shrink the compiler out and be able to support it in its current fashion. For other apps., even compiler may be shrunken out also. Perhaps we should take attendance of those who are working on these lines, and if there is enough interest set up appropriate communication mechanisms (like a Swiki somewhere).

squeak2.2 buglet in SequenceableCollection
by Douglas McPherson 25 Nov '98

25 Nov '98

I think I have come across a small possible bug in 2.2. 1) In SequenceableCollection>>asStringWithCr. The cascade of cr in the false block below is incorrect since the elements of the sequenceableCollection won't, in general, understand 'cr'. 'From Squeak 2.2 of Sept 23, 1998 on 24 November 1998 at 9:07:59 am'! !SequenceableCollection methodsFor: 'converting'! asStringWithCr "Convert to a string with returns between items. Elements are usually strings. Useful for labels for PopUpMenus." | labelStream | labelStream _ WriteStream on: (String new: 200). self do: [:each | (each isKindOf: String) ifTrue: [labelStream nextPutAll: each; cr] ifFalse: [each printOn: labelStream; cr]]. self size > 0 ifTrue: [labelStream skip: -1]. ^ labelStream contents! ! A possible simple solution: !SequenceableCollection methodsFor: 'converting' stamp: 'djm 11/20/1998 05:44'! asStringWithCr "Convert to a string with returns between items. Elements are usually strings. Useful for labels for PopUpMenus." | labelStream | labelStream _ WriteStream on: (String new: 200). self do: [:each | (each isKindOf: String) ifTrue: [labelStream nextPutAll: each; cr] ifFalse: [each printOn: labelStream. labelStream cr]]. self size > 0 ifTrue: [labelStream skip: -1]. ^ labelStream contents! !

Squeak MIDI and Mac Serial Ports
by Mark Guzdial 25 Nov '98

25 Nov '98

Does anyone know how to make Squeak let go of a Mac serial port after it uses it (say, for a MIDI interface)? On my G3 Powerbook, I have one lone serial port. After using it for MIDI-ing, I wanted to backup my PalmPilot, but it insisted that Squeak still had the serial port -- despite moving back to internal synthesizer, and despite quitting Squeak. I could backup after restart. It's not a huge deal (I don't backup that often :-), but if there's an easy solution (a Mac-centric thingie? A Squeak expression to evaluate?), I'd appreciate it. Thanks!
