What is StepTalk ?
StepTalk is a scripting framework for creating scriptable servers or applications. StepTalk, when combined with the dynamism that the Objective-C language provides, goes way beyond mere scripting. It is written using GNUstep.
Where to get it?
StepTalk requires GNUstep http://www.gnustep.org
You can download StepTalk from
Documentation for users and developers:
You need to have GNUstep which you can get from http://www.gnustep.org
To install StepTalk type:
> make > make install
If you do not want to build AppKit extensions, then type
> make appkit=no > make appkit=no install
If something goes wrong while build process and it is not while building in the Source directory, then try to do make and make install in that directory first. In any case of problem, do not hesitate to contact the author.
StepTalk Shell is included in Examples/Shell directory. It requires libncurses.

Sripting environment description
Scripting environment description is used to translate the method names and/or allow or deny the methods for concrete classes. Denying methods can be used to create safe scripting environment as prevention against script viruses.
It contains: - list of methods, that are available for scripting for particular class - symbolic selector (operator) to selector mapping - list of modules to be loaded - list of object finders
Standard vs. full scripting
Before each message send, selector is translated using scipting description. When standard scripting is used and there is no such selector avilable for scripting for target object, then an exception is raised. With full scripting, any message should be sent to any target object.
StepTalk is looking for its files in GNUSTEP_*_ROOT/Library/StepTalk There should be these directories: Configuration - Configuration files Environments - Directory containig environment descriptions Finders - Object finders Languages - StepTalk language bundles Modules - StepTalk modules Scripts - Directory containig StepTalk scripts
