monticello
by Stephen Pair 07 Jan '03

07 Jan '03

After giving monticello a quick test drive, it does seem like VersionNumber would be a nice fit. It would allow you to have the option of branching the development of a package. Right now it seems that monticello forces you into reconciling differences. It would also fit nicely into your repository file naming conventions. It was nice to see that when I had 2 images connected to the same repository and I tried to commit 2 different versions of the same package that Monticello detected that situation (when I committed in the second image) and forced me to update before it would allow me to commit changes. Then, when updating, it showed me the differences in the versions of the packages. It would be great to use VersionNumber to allow branching, but still give a warning message and confirm whether or not the user would like to a) update from the repository (as Monticello does now and avoid a branch) or b) commit a branch version of the package. In my experience there is a real need for branching support. It typically happens following a major release where you need to issue minor updates while simultaneously moving the product forward for the next major feature release. - Stephen

TrueType based TextStyle
by Yoshiki.Ohshima＠acm.org 14 Dec '02

14 Dec '02

Hello, I'm guessing there is something similar to this, but this is a change set that allows you to use TrueType based glyphs as a font for a normal TextStyle. You don't have to install any additional plugins, and the "default" glyph (MS Sans Comic) in the vanilla 3.2 image can be used once you file this in. One glitch is that when you rotate the TextMorph with a TT style, it loses the nice Anti-Aliased edge. I think it must be a matter of selecting right combination rule, but not quite sure which one and where is the place to fix. The following is the comment from the preamble. Enjoy, -- Yoshiki "Change Set: TrueTypeTextStyle Date: 29 November 2002 Author: Yoshiki Ohshima This change set will allow you to use TrueType based outline glyphs as a TextStyle. Once you load this change set, you will see 'ComicSansMS' style in the 'Change font' halo menu. You can add new styles by calling TTCFont>>newTextStyleFromTTFile:. I don't know where those TT fonts are located on Mac, but it should work if you specify the correct path. You definitely will want to try symbol.ttf:-) This change set was first written for the multilingualized Squeak and .TTC (TrueType Collection) file. The name of the class and the category name are reminiscent of it."

[ALPHA] Merchandise
by Marcus Denker 13 Dec '02

13 Dec '02

Hi! I've set up an account at cafepress.com http://www.cafeshops.com/squeakev Cafepress is a nice service that allows to set up a small shop for typical mechandising stuff (Mugs, T-shirts, Mouse-pads, stickers...). (see http://www.cafepress.com/cp/info/products/index.aspx) The nice thing is that it a) costs nothing to set up and b) they do all the work. The prices in the squeak-ev shop are a little higher than base price (.50 - $2), all profits go to Squeak Germany e.V. There are only 4 products set up because this needs to be testet first. Anyone in the US care to do alpha-testing? They have a 30-day-money-back garantee. Marcus -- Marcus Denker marcus(a)ira.uka.de -- Squeak! http://squeakland.org

[BUG] SeesColor Tile gone?
by Bert Freudenberg 11 Dec '02

11 Dec '02

I can't find the seesColor:/isOverColor: tile anymore. But the code is still there. Where did it go? Funny enough, the viewer for the car in the "Building with Squeak" project in the prebuilt Squeak3.3a-4981 image has a "test" category open still showing that tile. But in a newly opened viewer it's gone. -- Bert

[SM] SMCard subCategories
by Bijan Parsia 09 Dec '02

09 Dec '02

One thing I really like about SqueakMap is that it brings things to me. No need to go out and find the right web page or archive: SM brings it home to my image. Yay! Even better, it makes me want to pound on things, extend them, fix them, play with them, even write documentation. All to the good. For example, I loaded up MinneStore and it seemed to work ok, in some places, and not as ok in some others. Some things were just a bit disobvious, though with a bit of explaining, they would be clear. Some things needed a UnitTest or 4. Etc. I started doing a few of these things but then realized that I had No Good Place To Put Them. I could, of course, do the old go out and find the right web page, contact someone, send [BUG]s and [FIX]s and set up a Swiki page...ugh. No! I'm feeling lazy. I want *SqueakMap* to do this for me. SqueakMap is *magic*...it can fix *anything*. But my first impluse...to create Yet Another Package, seemed wrong. I don't want SM cluttered up with twelve dozen tiny packages, often with just 5 lines of code. I like the clean glowing lines of SM goodness. But I also want everything in SqueakMap. Basically, if each SMCard was itself also a SMCategory (or sufficiently like one) with a certain set of subCategories (e.g., Tests, FIXs, BUGs, Enchancments, Documenation, Request/Comments/Tips) then there'd be a natural organization of these bits and pieces and a clear association of them with the "parent" package. Seems to me to fit in with the use of SqueakMap for the Harvesting process...except that every package maintatiner gets to be their own Harvester. (E.g., there could be ways to indicate that a particular fix has been incorporated.) There are a couple of ways of implementing this, though it seems fairly straightforward, but I wanted to see what people thought first. Cheers, Bijan Parsia.

[ANN] CategoricalSMLoader on SqueakMap
by Bijan Parsia 09 Dec '02

09 Dec '02

Boy, it's amazing what you forget about #changed: and #update: and pluggibility. Anyhoo, a new version of the CategoricalSMLoader is now on SqueakMap. Yes, I admit it, I caved. Oh well. Enjoy. I just figured out that my install button in the fancy version is, well, much dumber than it should be. Consider this more an experiment in alternative not-quite-so-minimal SM UI designs. Cheers, Bijan Parsia.

[IMPORTANT] 3.3 is dead!
by goran.hultgren＠bluefish.se 07 Dec '02

07 Dec '02

Hi all! I just read a posting that implied that some people are not aware that 3.3alpha has been abandoned. Anyway, it HAS. So now you know. :-) 3.4alpha is where we are moving forward as we speak. But perhaps this should be stated on the www.squeak.org website too? And perhaps on Minnow somewhere? regards, Göran

Re: A big teacher wish

Stephane Ducasse <ducasse(a)iam.unibe.ch> wrote: all this is something that I really appreciated in VW7.0 and I think that it would save a lot of energy to teachers and to newbies. I would loved to rename classVariables as sharedVariables (what they are in fact). This way we could say instanceVariables, class instance variable and shared variables. "shared variables" sounds like the things you find in PoolDictionaries. It's a very poor name because it fails to reveal what's the most salient thing about these variables: each class variable is owned by some specific class and is visible within that class and its descendants. "class variables" are things that belong to classes. "instance variables" are things that belong to instances. It doesn't get much clearer than that. "class instance variables" are admittedly confusing, BUT they are also extremely rare. In the whole of Squeak 2.8 there were just four of them, in MorphicModel and Player. In 3.2 one of those class instance variables has gone away. There are now 13 classes with a total of 16 class instance variables: CardPlayer variableDocks ExternalStructure compiledSpec Interpolateable value InterpreterPlugin timeStamp MorphicModel prototype ObjectMemory timeStamp PhonemeSet arpabet Player scripts slotInfo Player157 cardPlayer111 unscriptedPLayer1 unscriptedPlayer2 Player176 player157 TestResource current UnscriptedPlayer ephemeralPlayerRef VRMLClassNode nodeSpec There are 1770 classes containing 5566 instance variables and 1288 class variables, so class instance variables are just 0.23% of the total number of variables, and more than that, are concentrated in a handful of classes that newbies are unlikely to be concerned with (at least until they are no longer newbies). It seems to me that teachers and newbies would save more time and energy by simply ignoring class instance variables completely than they would by changing the name of a core concept to be LESS meaningful and LESS helpful.

ThingLab Won't Filein
by Mark4Flies＠aol.com 05 Dec '02

05 Dec '02

I posted this message on September 28: "I am trying to use the ThingLab but I cannot get past installing it. I downloaded ThingLab v2 today. I am running Squeak 3.2.7 beta 6 (Carbon) updated to 4956 under Mac OS X 10.2.1 on an iMac. I open a new MVC project and file in the Predefs.cs without any trouble at all. As soon as I try to file in the other part, I get the message: < You may not create any more undefined objects - use nil. >" No one offered any ideas. I have confirmed the same problem under Windows 2000. If you know some thing about this software, please let me know if you have any suggestions. MUCH appreciated! -Mark
