Open Source Forth Interpreters for Mac

VolksForth is a 16bit Forth System with the goal to produce a manageable Forthsystem for computer systems with restricted system resources.

The Portable Forth Environment implements the ANSI Forth Standard, it is fully written in C, the newer version has a module concept, and it is fully multithreaded. Autoconf used. Tested in embedded environments.

A virtual machine providing a dynamic, portable assembler; JIT compilation; C bindings; and Forth semantics.

Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

Mops is a full-featured, object-oriented stand-alone programming language for Mac OS X. Its interactive development environment provides for fluid and productive programming by allowing quick testing and modification of small code segments.

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

This project originally was about a megaman clone called "Game Developer Man". Game Developer Man, the game, has long since tanked. However this project has moved on to the KRGP.

Forpost is an embeddable, interpreted stack-based(Forth-like) language which has simple, compact and effective implementation in ANSI C. Main features: heterogeneous arrays, higher-order functions, program/data equivalence.

OspreyForth is a personal project to make a customized Forth interpreter that can be used to create command-line scripts and general apps. It is currently capable of loading dynamic libraries and using external C code. In the future code that more directly attaches to the interpreter are planned so as to expand its abilities out-of-the-box.

16 bit Forth for PC. No OS required.

apForth is Another Portable Forth implementation started as pForth fork.

AVR interactive language (avrIL) is a forth like language for AVR processors.

bigFORTH is a native code Forth for x86 processors. MINOS is a portable GUI library for X11 and Win32, written in object oriented Forth, and includes the form editor Theseus.

Everything related to forth programming that has been discussed on the comp.lang.forth usenet newsgroup. The site is dedicated towards improving portability between forth implementations, providing surveys, example implementations, and library modules.

guiForth is a customized version of pForth that provides bindings to the FLTK library. The initial goal is to create a software development system for the Agenda VR3 PDA, but guiForth should be portable to any platform that has FLTK.

A Perl based interpreter for a language which is a blend of Forth and APL. The power of lang5 stems from its arrays operations in conjunction with the underlying Forth programming paradigm of bottom up programming.

A highly portable, Minimal ROM-able FORTH based on a small number of FORTH primitives.
