TextAttributes in OBDefinitions

[Newbies] TextAttributes in OBDefinitions

Hi Matthew, Hi Robert.

for step 3. try
self doOnlyOnce: [ self halt ] .

which can be primed by evaluating
“nil rearmOneShot”

That allows you to get the debugger you want and then
have the method  behave normally.

Hello,

thanks for the advices. I found out that the TextAttributes work  
perfectly well for OBDefinitions. The reason why I did not see a  
change when I added "TextAttribute bold" was the code font I used  
(Monaco). This font has no bold style so nothing happened. That simple.

You can also use

self haltOnce.

And to enable it: self setHaltOnce (does not have to be the same  
object).
In older squeak versions it is: self toggleHaltOnce.
