What is STk?

STk is a free R4RS Scheme interpreter which can access the Tk graphical package. Concretely, it can be seen as the standard Tk package where Tcl has been replaced by a Scheme interpreter. STk embeds also an efficient CLOS like object oriented system, called STklos, which provides:

  • multiple inheritance,
  • generic functions,
  • multi-methods,
  • a MOP (Meta Object Protocol)

STklos MOP is based on the Tiny Clos model from the Xerox Open Implementation group.

Distribution

STk is distributed in source form for Unix and Windows platforms. Distribution in binary form for some common architectures is also available.

Latest version of STk is numbered 4.0.0
