Squeak download stats?
by Thomas A Petersen 27 Feb '11

27 Feb '11

Greetings, FWIW, I download beta/gamma versions about once a month to test. Those that prove stable get my influx of current work for day to day use. I download the official version and move to it if it proves stable for my uses until about the middle of the next beta cycle. I also have a couple of friends that I pass the stable specialized images on to about once a year. A couple of other people I know pull the distribution for Windows and/or Linux when I let them know there is an official upgrade. Thanks again for a great place to think and learn, tap

TextMorph behavior
by Marcus Pedersén 18 Jan '11

18 Jan '11

Hi! I have been trying class TextMorph out for making an editable textfield for my GUI. One thing I can't figure out is how to make the text "grow" horisontaly when you write instead of verticaly. I am after the behavior similar to the spotlight search text field in mac. If you write loads of text the oldest text "dissapear" (visualy) on the left hand. I have tried autoFit: false and wrapFlag: false without any desired results. Doesn't TextMorph contain this functionality from start? Do I need to subclass and write the function from scratch? Many thanks in advance! Marcus

Error "opaque URL with no scheme--shouldn't happen!" after updating trunk from 10474 to 10500
by Hans-Martin Mosner 02 Jan '11

02 Jan '11

Hello, one of the changes which brought my image from #10474 to 10500 seems to have introduced a bug in the project switching code, however, I don't know where the actual problem is. The symptom is that the error message in the subject is raised in GenericUrl>>privateInitializeFromText: which is called via several steps from MorphicProject>>startResourceLoading. Did anyone else notice this? The bug is only triggered if your project has resources, of course. Cheers, Hans-Martin

Unicode strings, benchmarks
by Janko Mivšek 01 Jan '11

01 Jan '11

Hi Squeakers, I already extended String with TwoByteString and did a "scaling" with auto conversion to wider string when a wider character is put into a string. So far so good and this already works in Aida/Web. I also did a bit better UTF8 conversion but is only 25-80% faster that existing one in UTF8TextConverter. To prepare for even better results, I made a benchmark, which measure conversion time for English, French, Slovenian, Russian and Chinese 2500 characters long text. It measure 100 conversions which accumulates to 250K characters of text. Here are results in VW, Squeak with old UTF8 converter and a new one: VW old new english 30 313 248 ByteString, pure ASCII french 32 323 251 ByteString, ISO8859-1 (Latin 1) slovenian 48 578 480 TwoByteString Latin 2 russian 112 1306 720 TwoByteString Cyrillic chinese 107 1544 3825 TwoByteString Notice an exceptional 10x VW performance comparing to Squeak, and they do all encodings in plain Smalltalk! No primitives! So how come that Squeak is so slow here? Above benchmark was done on Squeak 3.9 on Suse Linux 10.1, P3.2GHz.

Open Cobalt on Squeak 4.1 is available
by Matthew Fulmer 12 Dec '10

12 Dec '10

Hi. Open Cobalt now runs mostly as it should on Squeak 4.1. It is not a finished port, but it is definitely enough to start playing with, testing out OpenGL, packaging it up for installation into current images, or whatever. Up to date instructions are kept at http://cobalt.cs.duke.edu/pub/INSTALLING.txt Reply with any questions. Current copy of installation instructions reproduced below. ----------------------------------------------------------------- Welcome to the beta version of Cobalt ported to Squeak 4.1 To run me, you will need: - the latest cobalt-trunk.*.zip file from http://cobalt.cs.duke.edu/pub/ - the latest opencobalt-1.0alpha*.zip from http://www.cs.duke.edu/~jdougan/downloads/1.0alpha1/ - A recent VM from http://squeakvm.org - http://ftp.squeak.org/sources_files/SqueakV39.sources.gz 1. Unzip the opencobalt-1.0alpha*.zip folder somewhere 2. Unzip the cobalt-trunk.*.zip file inside the opencobalt-1.0alpha* folder. It contains 3 files: cobalt-trunk.*.image cobalt-trunk.*.changes config/cobalt-browser.conf 3. unzip SqueakV39.sources.gz and put SqueakV39.sources into the opencobalt-1.0alpha* folder 4. run cobalt-trunk.*.image using your VM 5. Do this: CProjectMorph open: CobaltModularPanel 6. Click the menu item Cobalt > Start Cobalt == About this image == This image is a trunk image from November 2009, updated to the latest code in the trunk repository, except where that conflicts with Cobalt. Feel free to make a better image based on the current, 4.1 images. Known issues are listed at http://cobalt.cs.duke.edu/pub/cobalt41todo.txt -- Matthew Fulmer (a.k.a. Tapple)

quick handling of graphics files
by Ross Boylan 01 Dec '10

01 Dec '10

I have PNG files with document scans, and would like to view them as part of an application. I will also need to scale and/or pan them. One file took over a minute to open when I selected "open graphic in window" from the file browser. (ImageReadWriter formFromFileNamed: 'myfile.png') asMorph openInHand had about the same speed. I'm looking for advice on how to speed that up, or the information that is not possible. I found a similar question on the newbie list, but no one answered it. I'm guessing that it is the initial read and translation of the file that's taking the time, since resizing the image is much faster than loading it. This is really too slow to be practical, and much slower than imagemagick's display command, which opens in under 5 seconds. The image is a 400dpi black and white scan of an 8.5x11" page; the file is 144k bytes. BTW is there any particular reason the file browser opens a SketchMorph while asMorph on the ImageReadWrite result produces an ImageMorph? The former is closer to what I want since it is resizeable and not transluscent; on the other hand, the comment in SketchMorph says they are produced by the PaintBox, which is not true in this case. Squeak 3.10.2 on Linux with 32 bit color in X. I think squeak is using 32 bit color as well, but couldn't find the setting on a quick look (not in preferences browser).

New Trunk Image: 10548
by Casey Ransberger 03 Nov '10

03 Nov '10

Grab it here: http://ftp.squeak.org/trunk/Squeak4.2-10548-alpha.zip 2805 run, 2767 passes, 9 expected failures, 28 failures, 1 errors, 0 unexpected passes Mac OS X 10.6.4 (Squeak4.2.5beta1U) The error is in WeakFinalizersTest>>#testNewFinalizationSupported, which it would seem is not too big of a deal (just means the VM doesn't support Igor's new finalization stuff yet.) Brave and noble souls will download it on various platforms, run the tests, and generally make sure the image is good. -- Casey Ransberger

Fwd: RE: Where is Seaside download???
by Andreas Raab 14 Oct '10

14 Oct '10

Folks - Anyone knowledgeable up for making a Squeak4.1 based Seaside-ready image (or perhaps two: One with 2.8 and one with 3.0) that we can host on Squeak.org? I can feel the pain in the absence of the upcoming installer and it's something I think we can host reasonably easily on Squeak.org to make things easier for new users.
