Hi all --
My old adult Squeak has gone! My niece has been fooling around with it. I'd like to have my flap with all the standard adult smalltalk tools in it. Even my World menu looks different. Any ideas?
TIA.

if you have a latest image, the world menu should have "flap..." as a selection. In that selection you can turn on and off flaps.
Don't let kids play with Squeak! This is an adult software!

We also have your "robot factory" installed, Stephane. :-)) Last night I taught her looping, and she learned about variables, too. We had great fun!
Cheers,

Do not say it too loud! We should not have fun we are serious programmers. Real programmers like complex languages.

We installed your robot software and have been reading your book. She is going to go to the 5th grade, but I already taught her about varibales. We even refactored code!
Now, on a serious note - the Squeak environment is very complexx. We installed something (was it Smallland), and now I can't revert to the default evironment (the one that has the Tools flap).
How do I get it back? Sould I install a new image?
TIA
Stef,
I'm doing the Bots Inc thing with my son and we have a problem on the debugging section. When we code
self halt.
That brings up the debugger and then continues. It doesn't halt!
Done inside the 4 timesRepeat loop, it brings up four debuggers, all useless because the program keeps going and terminated before you can do anything with it.
Anyone have any ideas?

Hi Blake
I could be well off base here - I'm a beginner too!
Bert told me... "doOnlyOnce:" is essential for not getting a gazillion of debuggers. Read its comment to learn how to rearm it.
Here's how Bert suggested it be used with 'halt'.
self doOnlyOnce: [self halt].
As for why the system keeps running I can only suggest that its by design. Squeak is different to other languages because its actually an environment, and a remarkable environment with 'late binding' such that objects (classes and instances) can be dynamically changed during runtime. So you can debug - actually change code - without stopping the system.
Of course you may WANT to stop the system because defective code could be dangerous - but that would be different to what should be default behaviour for a debugger in the context of Squeak. To actually stop your code you'd have to send it a message that it can handle I guess :) You'd need a 'freeze' method.

self halt. is usually OK by itself (certainly for the beginning bots inc stuff). doOnlyOnce is particularly useful for debugging GUI event code that would otherwise keep firing (or really for debugging in a loop).
As for why the system keeps running I can only suggest that its by design. Squeak is different to other languages because its actually an environment, and a remarkable environment with 'late binding' such that objects (classes and instances) can be dynamically changed during runtime.

That's true enough, but the stack you are debugging shouldn't continue.
Unfortunately, I can't think what might be wrong. I've gone through Bots Inc without hitting this one.

I haven't had a chance to try this out but if it doesn't work...reinstall?
I downloaded the ReadyPC image from the SCGSmallWiki site and I am able to repeat the problem.
I think it is something wrong with the Bot Workspace. I am able to repeat your bug if I click the Do It or Do It All buttons in the Bot Workspace.
The good news is you can workaround the problem (by not using the buttons). Instead, press Alt+D or (Command+D on Mac) to invoke the do it command. This is what I normally do and explains why I didn't notice the problem when working through the book.
The Bot Workspace was added for the book. I bet the buttons worked at one point and a code change broke them. Went unnoticed because a lot of Squeakers already use the right-click context menus or the keyboard shortcuts.
I'm running windows. Can someone test on Mac and/or Linux?
