Open Source Forth 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.

Snd is a sound editor.

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, 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.

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. Feedback and bug reports are welcome per - Usenet forum https://groups.google.com/forum/#!forum/comp.lang.forth - email to minforth@gmx.net

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

A forth interpreter written in Ansi C, (found on the usenet_jan_94 cd) and is public domain. I have (mostly) ported it to OSX, and that's the version of the source posted here. It has bugs, so anyone willing to assist will be greatly appreciated. Originally by Allan Pratt. See https://github.com/pahihu/cforthu

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.

Yes, finally. The author decide to schedule some of his busy time to release the "Chinese Language Formula"- Step By Step. It will take a while, but eventually Chinese Language Processing is no longer a problem.

A 21 Century Boot system for the Tandy Color Computer series of 1980's computers. The aim is to create a unified, scriptable boot system for both new and old storage devices * THIS PROJECT HAS BEEN MOVED TO: https://code.google.com/p/legsforth/

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.

DruidBSD is a FreeBSD micro-distribution that supports CD/DVD, USB, and HD booting into a Live BSD Distribution.

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.

FurionMUCK is a modern MUD server based on TinyMUCK and Fuzzball extensions. It uses a MySQL driven backend storage engine for improved reliability, functionality, scalability and stablity.

Moved to http://www.fuzzball.org Everything here has been frozen for historical purposes. Fuzzball Muck is a networked multi-user MUD chat server. It is user-extensible, and newer versions (6.x) support advanced features such as GUI dialogs, through close client-server cooperation with Trebuchet or other clients that support MCP-GUI.

MAP is a software that allows to create and play text adventures. Text adventure or "interactive fiction" is software simulating environments in which players use text commands to control characters and influence the environment. They were among the first computer games. MAP includes tools to create the adventure and a runner that allows to play it. Source is available and open so both the runner and tools can be modified to fit the needs or style for each adventure/creator.
