Cross-platform (GUI) Programming Systems
Universal source handling system. Initially it was 'Newholon' welcoming the wide GUI and Web world. HolonU is programmed in Tcl since there are no comparable multi-platform Forth systems.
Forth interactive cross-compiler for Tcl/Tk. With HolonT you can write Tcl programs in postfix notation.
My universal source handling system streamlined. Its command set is optimal, I don't know what could be removed or added. HolonS is delightfully efficient.
A Forth system that uses Tcl/Tk as its native language. This system is independent of Holon. TclForth is available at https://github.com/wejgaard/tclforth.
