Re: [squeak-dev] The Inbox: Sound-hjh.16.mcz

P.S. I do not consider this fix to be a great idea (yet). The reasons why I have posted this 1) I would like to draw the attention to the class SampledSound (away from 'String', I do not like the idea of putting more things there) 2) I would just like to find out if there are some easy possibilities that we can make the sound library interface a bit more user friendly ('a small sound access DSL) --Hannes On Wed, 28 Apr 2010 15:24:24.473 0000, commits(a)source.squeak.org <commits(a)source.squeak.org> wrote: > A new version of Sound was added to project The Inbox: > http://source.squeak.org/inbox/Sound-hjh.16.mcz > > ==================== Summary ==================== > > Name: Sound-hjh.16 > Author: hjh > Time: 28 April 2010, 3:22:50.121 pm > UUID: 5859af18-61f2-4d48-83c9-f8703d57aeb3 > Ancestors: Sound-nice.15 > > playSoundNamed: aString > > does not play anything if there is no sound with the name 'aString'.

Refactoring Browser and Rewrite Engine for Squeak
by Chris Cunnington 26 Mar '11

26 Mar '11

I just changed the Squeak Wiki <http://wiki.squeak.org/squeak/227> entry about the RefactoringBrowser to what you see below. If what I've said is wrong, please say how. Also, the username/password for changing the Squeak Wiki is squeak/viewpoints. Anybody can contribute or update. Chris The RefactoringBrowser is now a series of menues in the OmniBrowser. You get the OmniBrowser in your system by executing this code in a Workspace. "Omnibrowser" (Installer wiresong project: 'ob') install: 'OmniBrowser'; install: 'OB-Morphic'; install: 'OB-Standard'; install: 'OB-Shout'; install: 'OB-SUnitIntegration'. "Refactoring engine and OB integration" (Installer ss project: 'rb') install: 'AST'; install: 'Refactoring-Core'; install: 'Refactoring-Spelling'; project: 'Regex'; install: 'VB-Regex'. (Installer wiresong project: 'ob') install: 'OB-Refactory'; install: 'OB-Regex'. Once you've done that, when you reach for a browser, it will ask you which of three browsers you want: Packaging, Omni, or regular. You can change from one to the other by clicking on a menu on the top rim of an open browser.

Browser whitewash
by Eliot Miranda 02 Mar '11

02 Mar '11

Hi All, while all these cool new browsers are great I get on well with the standard browser and my multi-window hack around it. But the multi-window hack shows up one major weakness with the default Browser, and that is it's use of list indices (systemCategoryListIndex classListIndex messageCategoryListIndex messageListIndex). These should just be systemCategoryName, className, messageProtocol (categories are in System-Organization; classes have protocols) messageSelector. If this happened the indices the browser has into the system would never become obsolete as does happen for example when one adds a class to a category, invalidating any classListIndex values into the same category, or systemCategoryListIndexes as happens often when the SystemOrganization changes on loading a package. So if anyone is looking for a small useful project, someone who probably has RB chops, how about reimplementing Browser so that it is essentially unchanged except for the indexes being ripped out, buried and stomped on? If someone did this I'd get round to using menu pragmas throughout and integrating the RB into the base Browser. cheers Eliot

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)
