Funge

See it's entry on gopherpedia:

Befunge in gopherpedia

So, befunge exist - more or less - in two flavors:

befunge93: with a limited playfield (80x25), less intstructions and a simple stack

befunge98: having an endless playfield, 1 to n dimensions, fingerprints (extension of instructions), stacks of stacks

In the last years I wrote my own implementation of an funge-machine in Common Lisp:

funge

It passes als Mycology[1] tests and some fingerprints are implemented.

A bit more interesting is my befunge-IDE:

toadstool

It allows to edit and watch code running in 1 to n dimensional funges.

Watching funge code is like having a transparent clock.

(btw, you'll also need my OOP approach to use ncurses, cl-tui)

tui - a common lisp framework for OOP style ncurses

The code is unfortunately bitrotten and just partly documented, as I haven't touched it in the last ~5 years. But any suggestions are very welcome.
