Re: /. mentions squeak
by Kevin Fisher 20 Nov '98

:) As a regular of Slashdot.org, I've been tempted to submit a story about Squeak and how wonderful it is...looks like someone beat me to it! Still...Slashdot will likely generate a lot of attention to the Squeak cause...heck, it'll probably overload the Swikis (the so-called Slashdot effect). Judging by the responses to the story, it looks like there are a lot of people who are very well informed about Squeak as it is (as well as the usual clueless trollers, but that's the internet for you :). Anyway, if the Swiki's seem overloaded....well, you've just experience the Slashdot effect. (For those who don't know: see http://slashdot.org) Another suggestion: Slashdot has a 'sister' web page called Freshmeat, which has more-or-less become 'the' place to announce new software for the UNIX/Linux community (see http://freshmeat.net). Is it in the interest of Squeak to have new releases submitted there? Again it would probably generate a lot of interest in Squeak... just a thought, anyway.

ummm... morphic errors
by Ryan Davis 20 Nov '98

"Sorry, for the moment you cannot tear off a new anonymous script for any instance of a uniclass other than the flagship instance. If this makes no sense to you, you surely got here in error" That is one of the better dialogs I've seen in a long time. :) So, anyone care to tell me what I did?

For those of you with RealAudio access, here's the URL to the CNET program which talks a bit about Squeak; the good stuff begins about 20 minutes in... http://www.news.com/Radio/Rams/1998/11/19/pm.ram?st.cn.News.radio.ne -- tim

Tentative 2.3 release schedule
by Dan Ingalls 20 Nov '98

20 Nov '98

Folks - I'm out of town for the weekend. It looks like Monday or Tuesday, we'll have most of the ingredients in the bowl, and I'll put out a beta release. There is so much new stuff that I doubt it will be cooked through in time for Thanksgiving. Therefore, I'm anticipating an official release more like a week from Monday or Tuesday. Just thought you would want to know. - Dan, for The Squeak Team

morphic scripting
by Ryan Davis 19 Nov '98

19 Nov '98

I am learning morphic with the intent of using it to teach my SO's son how to program. He REALLY wants to program games, but he doesn't have a clue about it at all, and I thought using morphic in an OO-logo fashion would be a very nice start... I'm not familiar w/ morphic at all, so I was happy to see that there is finally some documentation for beginners out there. Very cool. But I have some further questions.... (some of these may be obvious to those more experienced w/ morphic... I'd be happy to collect the results and put them on someone's swiki) 1) I wrote a method called touches: which is based on some of the logic in moveTowards: in order to have a test for collisions (which has obvious value to a 9 year old programmer-wannabe). I am now able to create a cat and mouse simulation where the cat can catch the mouse and make it attack (the mouse turns red when touched, the cat makes a noise when it touches). But the mouse code would be better if he could detect if ANY cat is touching him... Can it? checkBleeding | blood normal | blood _ (Color r: 1.0 g: 0 b: 0). normal _ (Color r: 0 g: 0 b: 1.0). (self touches: (self class refPlayer61)) " <--- here is the problem" ifTrue: [ self setColor: blood ] ifFalse: [ self setColor: normal ]! ! 2) I don't understand the model too well... From the debug menu, I learn that the mouse is an instance of StarMorph. But when I edit one of his methods it is an instance of a subclass of Player... Is this an analog to View and Controller? 3) Is there a registry of known players in a given morph? (possibly a shorter version of #1). 4) I assume that the costumes are akin to sprites? That way I could have several different costumes for a spaceship or car and have it rotate through them??? How? 5) Is there some clean way to get all my changes saved to a text file? I found the save morph, but they are at least partial binary files... 6) Any way to automatically clean or not generate these: !Player5 methodsFor: 'anonymous scripts'! xxxScript7 ^ self! ! 7) I can name a player in the debug menu, can I have something rename the class?

RE: Interfaces ala Java for Squeak
by Blanchard, Tod 19 Nov '98

I believe a better/more useful mechanism than interfaces would be something akin to ObjectiveC's Categories and Protocals.

Interfaces ala Java for Squeak
by GTE/staypufd 19 Nov '98

19 Nov '98

Hello all, I was wondering if anyone would like to see Squeak extended with something kind of like "Interfaces" in Java. I was thinking that this would be a nice way of documenting and inforcing at class acceptance time that a particular interface was fully implemented in terms of the methods being defined or inherited by a class. The idea is to extend the class definition right after the poolDictionary: section with something like supportedInterfaces: and when you did an accept, the methods defined on that interface would be auto-inserted with some 'self halt' code in the bodies of each one and maybe a call to super if the super classes supported the same interface. What do you all think? Sam Griffith Jr. staypufed(a)aol.com
