Thanks Lukas for the explanation. Every day I learn something new :)
Now I was wondering if we can change the onPrimitiveError: to something
like this:
onPrimitiveError: aString
| context |
(String
streamContents:
[:s |
s nextPutAll: '***System error handling failed***'.
s cr; nextPutAll: aString.
context := thisContext sender sender.
200 timesRepeat: [context == nil ifFalse: [s cr; print: (context
:= context sender)]].
s cr; nextPutAll: '-------------------------------'.
s cr; nextPutAll: 'Type CR to enter an emergency evaluator.'.
s cr; nextPutAll: 'Type any other character to restart.'])
displayAt: 10 @ 0.
[Sensor keyboardPressed] whileFalse.
Sensor keyboard = Character cr ifTrue: [Transcripter
emergencyEvaluator].
World install "init hands and redisplay"
I just changed to 200 timesRepeat instead of 20 so that to have the full
stack, or at least, more than 20 lines and also the point of displayAt:
10 @ 0. because in my case I couldn't see the first letters of the
windows.
If you are ok, I can put a slice in the inbox and create the issue.
Thanks
