interp target
in [TCL]
|
From: Bernhard van Woerden on 14 Jun 2010 11:46 I'd like to create a command alias and later do some introspection; firstly I'd like to know if the command is an alias and if so what the target is but $ proc foo {} {} $ interp alias {} bar {} foo but $ interp target {} $bar <empty list> as per the documentation for TCL 8.5 Does anyone have an alternative way to find the target ? Thanks Bernhard

You have a syntax error or three. This command works as expected. Jeff

This command works as expected. Actually, I see your confusion (though $bar is still wrong). 'target' returns "", which is the target interpreter path, and thus the right response. You want [interp alias {} bar]. Jeff
