Hi all,
So it's time for me to stop lurking and do some stuff. However, although I
am an experienced Smalltalk programmer (VisualAge Smalltalk continuously
since 1995), I am a complete newb when it comes to Pharo and Squeak, it's
hard to find my way around, and it's going to take me some time to get up to
speed.
I'm working on a small improvement to the testing framework, using ideas
that I have found to be very useful in my daily job over the past 15 years.
Note that I am doing this from scratch, so that I don't accidentally steal
anything that I've done in my work, but I know how it all works in
VisualAge, so I feel sure that I'll eventually be able to find the
corresponding classes and methods in Pharo.
What I would like are a few hints, clues and nudges in the right direction
for scenarios and questions that I will describe in this thread. What I
*don't* want are full-blown solutions, because then I won't learn anything.
I hope that some kind souls will be able to give me a little help in the
beginning that will eventually bring me up to speed and let me be
productive.
So to start with, one scenario and one question:
1) I want to find or write a method on Process that will print a stack trace
onto a supplied Stream. Ideally I'd like to be able to decide the start and
stop depth of the trace, so for example if I know that the top 4 stack
frames will always be uninteresting, I would want to be able to write
something like this:
Processor activeProcess printStackFrom: 5 to: 15 on: aStream.
2) What *exactly* is "thisContext"? It appears to be a reserved word in
Pharo, just like the familiar "self", "super", "true", "false", "nil" that
are always reserved in Smalltalk. I'd also like to get an idea of what it's
good for, and if anyone can describe it in terms of something that is in
VisualAge, that would be nice too :-)
BTW, if this is not the appropriate place for a thread like this, then
please tell me where I should put it (politely, of course :-p)

Cheers,
Peter
