Open Source Forth System Software for Windows

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."

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.

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.

16 bit Forth for PC. No OS required.

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.

The OS561 operating system based around FORTH/Java. The OS is to run on a VHDL chip OpenHardware design called the Minon, but could become available for other platforms. The unique point of the design is a revolutionary data compression technology.

OS for embedded and mobile devices based on tiny byte-code interpreter and FORTH language compiler (into platform-independent byte-code). In other word its smallest programming language realization works on any type computer with any OS
