Open Source Forth Software Development Software

4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, BASIC interpreter, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

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.

Ficl is a lightweight, efficient language designed to be incorporated into other programs, including (especially) firmware based systems. Ficl includes a simple but capable object model that can wrap existing data structures. Applications: scripting,

MinForth V3.4 is a classic Forth system with command-line interface. Development resource requirements are minimal. A source text editor and a C compiler are sufficient. By design no toolchain is required to adapt or rebuild MinForth. A complete rebuild takes only few seconds. Current sources are for Windows and Linux (32-bit or 64-bit). MinForth primitive definitions are written in mixed Forth and C language and are transpiled to pure C code. Main but not exclusive application for the transpiler is to build the MinForth V3.4 high-level Forth compiler. MinForth V3.4 is widely conformant to the Forth-2012 draft standard and passes the usual test suites.

FTH provides running stand alone Forth scripts like Ruby etc. and using Forth as an extension language to your application.

Compiler for a Forth-like language to make small binaries that use system calls instead of the C library

Forth compiler for the Compiled Virtual Machine

Calforth is a variant of the forth computer language. It will run as a forth interperter, as well as strictly compile an executable. Version 1.3 includes support for the 8051 processor and includes a processor emulator as well.

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.

This project provides a compiler that compiles ML into code suitable for execution on small targets, including embedded ones. The compiler generates both C and Forth.

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

Tools to incrementally build customised Forth Virtual Machines for embedded applications. Token compiler converts token description into C code templates. PC console application includes FVM, it is used to compile and debug bytecodes for target FVM.

Fifth is a exciting project to develop a new programming language that has all the capabilityits of C to develop low-level drivers, but uses a postfix syntax and has many high-level features from LISP and ML.

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.

Forth compiler written in MPL, Minimal Programming Language

A Portable Forth. It is aimed to be interpreted, or compiled to various architectures and VMs.

This is a simulator for the SMIS research MRI consoles. It executes compiled pulse sequences, and emulates the MR3040/50, MR3031, and RF cards. If you have an SMIS scanner, you will find this a useful pulse sequence development aid.

An English, German, Japanese, Portuguese, Russian, Chinese, Hindi & Bengali desktop OS loading from miniCD or USB key with applications and personal config files on floppy or USB key.

Wisp is a small Scheme-like language designed to be easily used in various structured data processing tools. The accent is on simplicity, automatical generatibility, and efficiency. (Currently on long hiatus. Gauche has similar goals and is maturer.)

apForth is Another Portable Forth implementation started as pForth fork.

Buggy C language implementation of my BIF 6809 variant of fig-FORTH. May be interesting to programmers with C background who want to understand the high-level version of the low-level of FORTH. Those requiring a functioning FORTH should look elsewhere. (The releases are usually out of date. Best to browse the code repository and download the latest snapshot.) There is now a basic how-to to get you started in the [wiki]. (The OSDN mirror at http://sourceforge.jp/projects/bif-c/ is becoming inaccessible.)

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