Safari plugin problem
by Randy Heiland 02 Nov '05

02 Nov '05

I'm just trying to figure out why the Squeak plugin isn't working in my Safari browser (OSX 10.x). From this page: http://www.squeakland.org/plugin/installers/mac-x-std.html the 'table of supported browsers' link is currently dead. I've downloaded it onto my Mac and I can run Squeak standalone fine. If anyone has a clue about getting the plugin working from Safari, I'd appreciate the help. thanks, Randy

Alternate realities, anyone?
by Joshua Fein 02 Nov '05

02 Nov '05

ALTERNATE reality Doing this right would be extremely technical, in terms of abilities required to implement. I myself do not yet possess that ability, and in truth have only a limited desire to discuss the pro & cons of the idea. Successful implementation would involve re-thinking what happens when a class gets re-defined, a very complex, system-level task. "Categories" would have to be viewed as more fundamental units, perhaps. Another tier, "Alternates" above "Category" might resolve the problem. Have to think about this more. Having it mesh with the current "world" "project" scheme would be a plus, only that is so complicated! ALTERNATE worldS --->right now the categories are only place-holders, 'comments' they do not have any effect on the system itself. --->right now, when a class with an existing name is reentered under a new category, it is removed, and it's unique methods added to the class entered under the new category. --->I was proposing that a change be made so that: --->Classes may have the same names but be in different categories. depending on what 'world' or 'project' ('alternate' flagged world) you are in, the class being referred to may be in one category or another. ---> only complex when 'active' i.e. there are two worlds which use the same class name but defined under different categories. Otherwise the Squeak environment would look just like it does now. ---> idea similar to versioning but applicable to the application environment. start with this example: You have a class SlideShowMorph under the classification SlideAuditor. You have another, differently defined SlideShowMorph under the classification SlideShow. When smalltalk reads the second classification, SlideShow, it creates a 'project' or 'world' for which that definition of SlideShowMorph is valid (and ... a) an entry "SlideShow" in another level above 'category' ('Alternates'... unless 'Universe' behavior could be modified?) or b) maybe as another kind of category? ("SlideShow" the 'Alternate' flagged category) or c) a special flag on the the class itself? (the 'Alternate' flagged SlideShowMorph) or d) All of the above? At the 'top' level, only the minimal set (In this case, all classes in the current version of smalltalk, since none of them conflict) , of the non-conflicting classes are accessible. to access the conflicting classes, one has to be in one 'world' or another. (i.e. the "SlideAuditor" world if SlideShowMorph was included as part of the minimal set) ALTERNATE programming environments, ALTERNATE careers... The bottom line may be that smalltalk as it is defined in Squeak simply is not flexible enough to allow this sort of construct, that one would end up with a system that is a mere bastardization of itself, like the "objective" C environment I am currently trying to use on the Mac... which is still successful, because in Xcode/macland, it's still the only game in town (If ya wanna be a programmer, that is). the taxi drivers grumble, but hey,no mac programmers are complaining. So it COULD be done... IN A FUTURE LETTER: Why the taxi-drivers grumble, how to make squeak more consistent with itself. __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
