David,

I know it's not a problem for me anymore. I have been able to run the full tutorial. It's also faster, I can run it on my iBook/600.

Arjen.

PS It seems some applications, like a webbrowser, have been removed. Don't these work any longer or is this a licensing issue ?

Sekhar,

Is this still a problem for you with 4.1.5?

Thanks,

The web browser was available in the Demo snapshot in early 4.1 releases but with a warning that neither it nor the screen sharing feature worked on the Mac. I didn't notice that it had been dropped, but the recent focus has been on the Mac so I am not surprized. Also note that the web browser was created in 1995 and can't handle tables, backgrounds, frames and other things that are important (unfortunately, in my opinion) in most of today's pages.

The only other thing that is no longer available (I think) is the Smalltalk emulator. I have made a 4.1 snapshot derived from BareBones.snap and including Smalltalk available as (5.8MB):

http://www.merlintec.com/download/Smalltalk.snap

This isn't very convenient. It would be better to have the applications loadable separately rather than a full snapshot. Normal text modules aren't quite enough for this. The transporter also has code for binary modules, but I never tested them.

It's not really about the webbrowser. It's more a question of examples of how one could program with self. I've read somewhere that the browser used a very object-oriented instead of class-oriented way. Morphic on the other hands looks to be much more class-oriented.

It is certainly written in a different style in that everything is bundled up in a single object (an oddball called "webBrowser") in globals. This acts as a separate namespace for everything in the application (nothing in "traits" and other places).

Everything I have written has also been in this style instead of what the papers, the tutorial and most of the older Self code is like. I am not sure that it is less class-like than the rest though at least there are no copyDown slots like in Morphic.

Also, OSX is just bsd unix with a different UI so maybe the webbrowser works again?

Just a guess, but the problem was likely to have been with the networking code. As you said, the Solaris socket stuff probably compiles unchanged in OS X.

Thx I'll look at it. Does this snapshot work with 4.1.5 ?

I have just tested it and it seems to be working. The first thing I tried (inspectIt on "3+4") didn't work because object "7" doesn't understand "class". I tested it in Self 4.0 and it was already like that, so this isn't a case of bit rot...
