Guest post by The F-Script project has announced the availability of F-Script 2.0, a set of open source tools for dynamic introspection and scripting of Cocoa objects on Mac OS X. The package provides Mac OS X developers and power users with graphical tools for exploration and interactive manipulation of objects. It also provides programmatic tools for scripting, in the form of a Smalltalk dialect directly hosted on top of the Objective-C runtime. This new version of F-Script introduces major new features including system-wide scripting, dynamic Cocoa class creation, 64-bit support and automatic garbage collection.
