Open Source Forth Software

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

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

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).

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.

FlashForth is a standalone Forth system for the Microchip PIC 18, 24, 30, 33 and the Atmel Atmega series of microcontrollers. A Forth system with interpreter, compiler, assembler and multitasker is provided.

Unofficial user documentation for the Mecrisp-Stellaris Forth programming language on ARM Cortex-M microprocessors. Includes a index, search function, projects, pictures and Youtube video links. This Documentation is designed for Forth Beginners.

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

Snd is a sound editor.

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

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."

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

acSMTP is a SMTP/POP3/IMAP mail server for Win32. May serve MX hosts and in-LAN mail. Black/white lists for IPs/Emails, RBL spam blocks, DNS Email validation, optional DBMS backend for lists and rules, custom user authorization, AntiVirus API.

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.

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.)

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.

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.

As a console terminal, TermFF, with its extensions, connected to a Forth system device can be used as a software development environment.

pFFh is a programming language that allows you to launch applications on embedded systems safely, quickly and comfortably. pFFh runs on the target system, combining operation as a command interpreter and code compiler. We can say that pFFh behaves like an operating system on the board under development. All pFFh needs is a serial or USB-serial channel to communicate, and through it, receive and process console commands, either from a keyboard or from files sent from a desktop computer. At present, pFFh is implemented for the PIC18FxxQ4x/Q7x family of microcontrollers. The code has been run and tested on the PIC18F16Q40, PIC18F16Q41, PIC18F57Q43 and PC18F56Q71 "Curiosity Nano” boards.

acFTP is an OpenSource replacement for Microsoft FTP server and other proprietary FTP servers for Windows. Unlike MS FTP, acFTP supports extended FTP commands set, including APPE and REST for resuming broken uploads and downloads.

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

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.

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.
