Hi Yavor,
Thank you for the instructive answer.
I simply found the whole 'documentation' and the 'reference' folder in
the source folder of 'libs-steptalk'.
Also the 'Shell' folder under 'Examples': I built and installed
stshell I was missing.
So I have now all is needed to learn and practice about scripting
within GNUstep.

I don't understand this statement. StepTalk is modularized; the
Foundation module should always be installed. The method names must
match those in GNUstep Base, not some methods that exist(ed) in
Smalltalk. StepTalk is a fresh implementation from ground zero, it
does not rely on anything from Smalltalk.
When I try some other commands, e.g.:
'Hello' indexOf: $e
I receive such an error message:
stexec: Uncaught exception STInternalInconsistencyException, reason:
No method signature for selector 'indexOf:' for receiver of type
GSMutableString
That's correct and a proper error message; there is no such method.
What are you trying to do? You can get a list of the methods from the
Base API reference documentation, which is also online at gnustep.org.
$ stshell
Welcome to the StepTalk shell.

- Do we need to install a complete Smalltalk runtime to use StepTalk
within GNUstep?
You don't need anything from Smalltalk (neither the original Smalltalk
nor the GNU Smalltalk implementation) to use StepTalk, it has nothing
to do with it apart from inspiration (which is more or less true for
the Objective-C language as well).
- Is the StepTalk Framework limited with GNU runtime?
You mean the GNU Objective-C runtime? Haven't tried, but I'd be very
surprised if it is. That would be a bug worth fixing.
Cheers,
Patrick
