Macintosh command line script?
by Howard Stearns 31 May '08

31 May '08

How do I pass in the name of a script to run when starting squeak from a Macintosh command shell? I thought it was: <vm> <imagename> <scriptname> otherArg1 otherArg2 etc But that doesn't seem to be working on Mac: Smalltalk getSystemAttribute: 2 => '' although lower or higher integers work as expected, and 2 works as expected on Windows and Linux. For <vm>, I mean something that reaches inside the Mac .app, like squeak.app/Contents/MacOS/VM In my case: Smalltalk getSystemAttribute: 1006 => 'Mac Carbon 3.8.12b5 6-Jun-06 >BA037700-B8B0-4089-B25E-338707613B8A<' and Smalltalk getSystemAttribute: 1001 => 'Mac OS' -Howard

Revising Squeak 7175 (3.10.1)
by Jerome Peace 31 May '08

Revising Squeak 7175 (3.10.1) Hi Ken, Hi Edgar, Hi Klaus, First appreciation. It is very good to see fixes to 3.10 come out and to see a project run to schedule. Second appreciation in the form of critism. I just downloaded the revised 3.10.1. The first thing it tells me is that it is broken and that I should click for an update and save the image. Everybody who down loads squeak must do this. Does something about this sound wrong to you? A revision to fix mistakes should not need user interaction to fix mistakes made to the revision in the last step. First, you wonder why the releasers just did not do those two steps before the release. Second, if you look into the problem you will see that updating to 7175 from the update stream avoids the mistake entirely. The phantom catagory is not there. The downside of doing it this way is that the changes file is not condensed. So why not add a changeset with postscript to do only that? Then release the result? Yours in service and curiosity, --Jerome Peace

Squeak 3.10.1 is a release meant to correct a handful of problems found in 3.10 soon after it was released. This was a quick release completed in just over two weeks and includes 16 updates addressing issues related to Date and Time, Morphic, Fonts, Tests, Streams and Collections, and improving the Welcome window. This release includes 2252 tests of which all but one now pass. The release along with related files can be found at http://ftp.squeak.org/3.10/ I want to give special thanks to Edgar J De Cleene, Keith Hodges, Jerome Peace, Nicolas Cellier, Andreas Raab, Dave Lewis, Yoshiki Ohshima, and Randal Schwartz.

How to control start-up memory on Windows XP
by itsme213 30 May '08

30 May '08

I'd like to have my VM always start up with (say) 200MB memory. I've tried: squeak.exe -memory: 200 myImage.image but it still shows up with 56M memory usage (in windows task manager). Am I doing something wrong? Mis-interpreting what I see? Thanks ... Sophie

[Packages] Packages Team and List rejuvenated!
by Keith Hodges 30 May '08

30 May '08

Dear All, now that we have Installer, LPF, SqueakMap, Universes, DS, MC2, and Sake/Packages we have never had so many different solutions for packaging and loading our stuff. The packages list has been dormant for a long time now, so I am aiming to give it a fresh start. We shall begin by supporting the http://www.squeaksource.com/Packages repository, and see how we get on. Commits will be automatically posted to the list from squeaksource (thanks matthew). Informal bug reports on any of the above items will also be welcome, though of course mantis is the preferred place for formal bug reporting. So.... What exactly are we aiming to achieve? GOALS ====== The first goal is to use Sake/Packages to create a definitive model of all squeak packages, which versions load into which images in what order, for both stable and unstable releases. So far we have separate packages with definitions for: PackagesSqueak310 PackagesSqueak39 PackagesSqueak38 PackagesSqueak37 PackagesSqueakMap (auto generated from SqueakMap itself) Other projects, croquet, sophie, etoys, and pharo are most welcome to have their own package in this repo, or elsewhere if preferred. General unstable/latest package definitions are placed higher in the class heirarchy, with more specific "this definitely works" definitions in leafier subclasses. To install sake/packges Installer install: 'Packages'. or Installer install: 'PackagesAllVersions'. Do subscribe to the packages(a)lists.squeakfoundation.org to give feedback on what does and does not work correctly. If you are a Universes user and have noticed any problems with Universes, then we can absorb that knowledge into the model, and poke universes maintainers to pick up the new data. many thanks in advance Keith p.s. if you are on the pacakges list and this new flurry of activity makes you nervous please feel free to complain. p.p.s. emails sent to the list by non-subscribers should get through eventually, if you just want to report a problem but not discuss it further.

Creating/using MIDI ports with external device, how to start?
by John Richards 30 May '08

30 May '08

I'm trying to open a midi port to receive incoming midi commands and am completely stuck (after a week of trying everything I can think of). I've confirmed that the MIDIPlugin is loaded. I've tried on both Windows XP and MacOS. The only port I have available is this: MIDI Ports: 0: QuickTime MIDI (out) Everything I have tried to create a new one has failed in the midi open primitive. I suspect I'm just being dumb and there is an obvious incantation (hope so anyway). Thanks so much for any advice you can provide. John

Fwd: [squeak-dev] Renaming "Squeak"
by David Mitchell 30 May '08

30 May '08

Wow, this thread came alive from the archive! Note that I wasn't advocating for or against brace notation. But, if you are trying to write code that is portable across Smalltalk dialects, you avoid brace notation. On my projects, I would rather maintain: dictionary := Dictionary new at: $a put: 1; at: $b put: 2; at: $c put: 3; yourself. than { $a -> 1. $b -> 2. $c -> 3 } asDictionary As I think it would be easier to update. I use literal forms to save myself typing but when I commit code, I'd rather have the long form. In fact, I've sent #sourceString to literal arrays so I could get the long form without all the typing.

[ANN] New FunSqueak 6
by Edgar J. De Cleene 30 May '08

30 May '08

I put a new FunSqueak3.10alpha.7.image. To list of previous packages, I add: Scamper. Celeste. InstanceEncoder OSC To web team , please update the info and links. http://ftp.squeak.org/various_images/FunSqueak/FunSqueak3.10alpha.7.zip To Stephanne Rollandin, I put all prerequisites Musical Objects need, still polishing details for having a small part of you super work into the image, hope I could do for the next . RePlugin is specific for each OS, so each need download and put into the right location. Maybe could be replaced by Vassily Regex , slower but only Smalltalk ? You tell me. I put the relevant updates of 3.10.1 into and set the depth to 32. Add the WelcomeWindow of 3.10 and the history of 3.10, remove Rosario photo and SSI photo of New Worlds of Squeak project to request of Serge. Enjoy and send feedback Edgar

[ANN] Haru PDF Library binding for Squeak
by astares＠gmx.de 30 May '08

30 May '08

Hi, "HARU is a free, cross platform, open-sourced software library for generating PDF" - so why not use it from Squeak. [1] includes a first rough version of a binding for the free Haru PDF library [2]. It's not fully complete but usable to start printing. Use at your own risk and feel free to help moving it forward (MIT License). The squeaksource repo is read/write. See examples in class PDFDocument to get started. Since it uses FFI an external library for your platform is required [2]. Place it next to your SqueakVM. Happy printing Bye Torsten [1] http://www.squeaksource.com/HPDF.html [2] http://libharu.sourceforge.net -- Super-Aktion nur in der GMX Spieleflat: 10 Tage für 1 Euro. Über 180 Spiele downloaden und spiele: http://flat.games.gmx.de

If the only port you have is for output only, trying for input seems futile perhaps? ----- Original message ----- From: John Richards <ajtr(a)us.ibm.com> To: squeak-dev(a)lists.squeakfoundation.org Sent: Thu, 29 May 2008, 12:09:20 BST Subject: [squeak-dev] Creating/using MIDI ports with external device, how to start?
