Pan/0.14.2 (This is not a psychotic episode. It's a cleansing moment of clarity.) |
(Note I am using:
cvs -q -d \
":ext:anoncvs@savannah.gnu.org:/cvsroot/gnustep"\
update -dP -D 20041203 gnustep/dev-libs/StepTalk)
I tried the following example code from ESUG2003 slides:
| object method source engine |
object := STScriptObject scriptObject.
engine := STEngine engineForLanguageWithName:'Smalltalk'.
source := 'sayHi Transcript show: \'Hi.\'. ^self'.
method := engine methodFromSource:source
forReceiver:object
inEnvironment:Environment.
object addMethod:method.
object sayHi.
with stexec and I receive the error:
"stexec: Uncaught exception STInterpreterGenericException,
reason: No execution environment set"
I can get the method to execute 'manually' by using
"executeMethod:forReceiver:withArguments:inEnvironment:".
Why can't I get it to work as written?
Thanks,
Matt
