Open Source Forth Software Development Software

Mecrisp - A family of optimising native code Forth implementations for MSP430, ARM Cortex M, RISC-V RV32IM(C), MIPS M4K and FPGAs.

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.

Thinking Forth captures the philosophy of the language to show users how to write more readable, better maintainable applications. This project makes the book available in electronic form (LaTeX and PDF).

ANS Forth for Win32 and Linux/x86 (used to compile the following SF projects: acWEB, acFTP, acFreeProxy, acSMTP, Forth-Script)

Win32Forth is ANS compatible, Forth language application development system with many tools; Interactive console, integrated extensible debugger, a GUI file editor, hypertext rendering, hyperlinked source files. VIEW <word-name> to explore the many files

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.

colorForth is, in Chuck Moore's own words: "A dialect of Forth that uses color to replace punctuation. Includes its own operating system. Produces extremely compact programs. Instant compile from pre-parsed source."

Tachyon was originally developed for the Parallax Propeller 8-core MCU because I need to do more and faster, and within the the limited memory, in order to produce firmware for my commercial embedded hardware products. When the much vaunted successor, the P2 was introduced, then Tachyon was upgraded and also built into the P2 ROM as TAQOZ. Source code can be sent or pasted from the PC terminal at high speed (921,600 default) without any terminal delays and compiled into RAM ready for backup into SD or Flash. TAQOZ RELOADED, the full version of Tachyon for the P2 can be booted from SD cards or Flash and has all the tools needed to develop and test code interactively on the target MCU. Please browse the wiki pages for howtos and information on all matters regarding Tachyon/TAQOZ and the P1 and P2. There's even a Tachyon layer that runs on Mecrisp on the RP2040 too and now the ESP32-C3 as TachyonESP which uses the Arduino IDE to build the kernel.

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

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

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.

THE SOURCES HAS BEEN MOVED TO GITHUB https://github.com/josefpavlik/picoforth PicoForth is Forth compiler for PIC12 and PIC16 families. It is written in gForth and requires gpUtils. Produces hex file ready to be programmed into the device.

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.

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.

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

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

Forth interpreter done for .NET. Just a way to learn Forth, CIL and more C#.

Rainbow Forth is an implementation of the colorForth dialect of the Forth programming language designed to run under Linux or Windows.

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.

WMForth : Forth compiler written in C for Pocket PC with ARM processor running Windows Mobile, compiled with Embedded Visual C++ 4.0.

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.
