Projects / Gforth


Gforth is a fast and portable implementation of the ANS Forth language. It works nicely with the Emacs editor, offers some nice features such as input completion and history and a powerful locals facility, and it even has (the beginnings of) a manual. Gforth employs traditional implementation techniques: its inner innerpreter is indirect or direct threaded. Gforth runs under Unix, Win95, OS/2, and DOS and should not be hard to port to other systems supported by GCC.

        I've been using Gforth for 6 years, as development base for interactive assemblers for ADSP-218x and ADSP-BF503, and on top of these an RTOS with token-threaded virtual machine for RTC-communicating alarm systems, described in an EuroForth2004 article ( Thanks Anton and Bernd!
