Release 3.1 or 3.2?
by Dan Ingalls 02 Dec '01

02 Dec '01

Folks - I am now "clearing my desk" prefatory to finally getting Henrik's Modules out (sorry, I just got swamped a month ago). One thing that remains to be completed is to release 3.1, but as I reflect on this, I wonder if we mightn't just put 3.2 into gamma status, let people beat on it for a week, and release THAT instead. Here are some reasons: It has a bunch of cool new stuff not in 3.1 It seems pretty stable If has if anything more fixes than 3.1 right now We are (honest ;-) about to enter a real test-pilot period I don't care a lot one way or the other, but I think this would be a bit less work for me as well. How to make the decision? Well, assume I've decided to do this, and only send mail if you are strongly opposed. If no one complains in the next day or two, that's what I'll do. Thanks - Dan

MPW complained about a missing jpeglib.h I downloaded a package from the independent jpeg group's ftp http://www.ijg.org/files/jpegsrc.v6b.tar.gz This package includes a jpeglib.h. But MPW still complains about a missing jconfig.h file. This file was not in the package I downloaded. Do I need to build the jpeg library to compile this plugin? Seems like I would need CodeWarrior to build the jpeg library on a mac. Karl

[updates] 10 for 3.2a
by Dan Ingalls 02 Dec '01

02 Dec '01

Folks - Now out on the servers, some pretty interesting goodies... First, in time for the holidays, we have two classic games. Mines from David A. Smith is ready to gobble up your spare minutes and hours. And an entire game of Chess, from Andreas Raab, which he says needs a bit more programming to play a decent game. Who wants a Squeak game that needs more programming? Oh, I see ;-). There are several bug fixes, plus a whole rewrite of Morphic borders from Andreas. Lots of cool new styles are now available. Then there's a high-speed reader/writer for JPEG format from Juan Manuel Vuletich. And streaming sound support from John Maloney. Last, but not least: An entire JPEG movie morph from John Maloney and Juan Manuel Vuletich. You mean MPEG, don't you? No! Juan's JPEG plugin is so fast that you can show movies from it at 30-40 frames per second. This means we have a movie format that is open, can be written from Squeak, and is something like 20 times more compact than our old .movie format. Check them out - Dan -------------------- 4543hideTabsFix-sw -- Scott Wallace -- 24 November 2001 Fixes the bug that could drop you into an endless series of debuggers if you hit the 'hide tabs' button in a flap-based Navigator tab" 4544Morphic-Chess-ar -- Andreas Raab -- 25 November 2001 A long-term project of mine has always been to write a nice little chess program for Squeak. But since I haven't done anything on it in the last few months I'm just going to throw it at the community to see if someone is interested in doing a bit more. It's a playing ... but not well :-( So, go get it from the objects tool and improve it!" Smalltalk at: #ChessConstants put: Dictionary new. 4545Mines-das -- David A. Smith -- 25 November 2001 Ah ... one of those terribly addicting games..." 4546projEnter-sw -- Scott Wallace -- 25 November 2001 Fixes a recently-introduced bug regarding the initial state of morphic projects." 4547viewBoxFix-crl -- Craig Latta -- 5 November 2001 Initialize the fullBounds of a pasteup when its viewBox is set -- fixes a bug seen when entering a newborn project that has no submorphs in it. " 4548BorderStyles-ar -- Andreas Raab -- 26 November 2001 This change set introduces explicit border styles in Morphic. At this point they are hacked into BorderedMorph to allow the dual existance of the borderWidth/borderColor pair with the new border styles (e.g., storing a value into borderWidth/borderColor will be reflected in the borderStyle when it is used). Six new complex border styles have been added - besides 'rounded' versions of inset and raised borders (as well as their inverse variants) framed borders are supported. The new border styles are available from the object properties dialog (e.g., when you click on the 'change color' halo - which really should be renamed). In addition, each border style can either track the color from its associated morph, or it can have a fixed color. It is therefore now possible to have a morph with a gradient fill and a manually selected color with a raised (or inset, or framed) border style, thus greatly improving the results for any fancy fill styles. 4549fastJPEGReadWriter-jmv -- Juan Manuel Vuletich -- 26 November 2001 JPEGReadWriter2 uses a free JPEG library from the Independent JPEG Group to provide: 1. encoding, as well as decoding of JPEG images 2. very good performance It has many applications, including JPEG movies. Many thanks to Juan Manual for this splendid addition to the Squeak toolbox!" 4550streamingSound-jm -- John Maloney -- 26 November 2001 Adds support for the creation and playback of monophonic streaming sampled sounds. The sounds can be compressed using any of Squeak's sound codecs. Random access (i.e. moving the playback position) is supported. Compatible with StreamingMP3Sound. Note: Random access does not work perfectly with the ADPCM codec. A fix is forthcoming. For now, mulaw or gsm compression are recommended." 4551jpegMovie-jm -- John Maloney -- 26 November 2001 Exploits the new fast JPEG plugin to support a new, compressed movie format: JPEG movies. A JPEG movie file (usually ending in '.jmv') contains a header, the JPEG compressed frames of the movie, and possibly one or more sound tracks. Like a Squeak movie--and unlike an MPEG movie--JPEG movies can be created, manipulated, and edited using only Squeak. However, they are much, much smaller than Squeak movies. For example, a several minute clip from Fantasia ('Night on Bald Mountain') shrunk from about 176 to under 6 megabytes. On the other hand, JPEG movies tend to be 1.5 to 3.0 times the size of an MPEG movie at a similar quality level. The class JPEGMovieFile contains methods for converting both MPEG or Squeak movies into JPEG movies. JPEGMovieFile implements a subset of the MPEGFile protocol so that JPEG movies can be played by MPEGMoviePlayerMorph. Also included in this changeset: 1. the ability to resize the movie display (use the yellow halo) 2. improved sound/picture sync that is robust in the face of sound pauses induced by OS activities 4552borderStylesInViewer-sw -- Scott Wallace -- 26 November 2001 Makes the full range of new border styles available in viewers"

Finding Plugins: MPEG files not valid?
by Mark Guzdial 01 Dec '01

01 Dec '01

I'm eager to try the Movie-JPEG format, but I can't get any MPEGs converted to Movie-JPEG. The problem isn't the JPEG plugin -- I can't open any MPEGs! I know that I used to be able to, but in a completely-updated 3.2 image, running the 3.1.1 Mac VM (not OS X), every MPEG or MP3 file I try comes back as being invalid MPEG. These are files that I can successfully play in QT Movie Player and in iTunes. I've been wondering if I even have the MPEG plugin -- maybe the primitive is bombing because the module can't be found. I've tried downloading the MPEG plugin from www.squeak.org in the 3.0/mac/extra_files directory, but with the same result. Some questions: - Is there a more recent MPEG plugin somewhere? - Is the MPEG plugin built in to the Mac VM? How can I find out? I know that there's a way of getting an array of all the available plugins, but I can't find it anywhere in the image. - Are there specific MPEG versions that work or don't work? - Can anyone point me to valid MPEG files that Squeak can read that I can try this?

Squeak-ing myself...
by Giovanni Giorgi 01 Dec '01

01 Dec '01

Ciao! I am a very very Squeak-fan and I'd like to help squeak growing ;) I know well Squeak 2.x and Squeak 3.0. I am not a wizard, but I had used Smalltalk for writing simple projects (see http://daitanmarks.sf.net) and I had programmed in Smalltalk during the last 4 years in my spare time (my job is java- centric). I'd like to help squeak community in my free time. So, if you have some code or documentation to write...I would like to help you... ...can I? Give me a hint! // Giovanni JJ Giorgi http://daitanmarks.sf.net // ^. .^ http://www.squeak.org // ='= Smalltalkers do: [:it | All with: Class, (And love: it)] // Sol-Tec Soluzioni Tecnologiche S.r.L. http://www.sol-tec.it

Weather maps?
by Dan Ingalls 30 Nov '01

30 Nov '01

Folks - We now have access to network spelling correction and translation in Squeak. Something else I like to see sometimes is an animation of the last 6 weather satellite images of my area at 1/2-hour intervals. Weather.com provides this nicely, but it would be even nicer to have it in Squeak, and separate from all the ads and inaccurate forecasts. Plus it galls me that they don't cache the background image of the ground (I think) -- it should be able to ship the precipitation overlays in just a couple of seconds, but it seems to take quite a long time. Anyone know enough to put this together? TIA - Dan

RE: SUnit Testing merged with Examples for Methods

We have found it useful to organize tests into categories (unit test, integration, performance, hmm - we now have a "broken" category). We have a different TestRunner that allows you to select the categories that you want to run (and some other enhancements). It has proven useful to run all of the unit tests without running the time-consuming performance tests, or vice-versa. At the moment, this is all in VW and uses VW's pragma facilities for categorizing test methods. Add as many <category: #cat> lines as you want to a method, save and it shows up in the test runner. Assuming nobody wants to volunteer to implement a similar pragma facility; an alternative way to do this is to use the standard method category with a naming convention (SUnit-performance,...) instead of relying on a naming convention for methods. -david

How about a status description in each class: stable, experimental, deprecated, or whatever?
