What's the simplest language to implement?
Forth compiler in 159 lines of Lisp and C
- lbForth: A self-hosting metacompiled Forth
-
Forth on the XMOS CPU?
Probably what I would do is write a minimal forth interpreter in C, and then use that and a few core words to bootstrap the rest of the system. It is a bit more complex than that, but here is the software which does it.https://github.com/larsbrinkhoff/lbForth
