Forth-ish

Nov 03, 2025

A spin-off of the Toronto Lisp Users’ Group is a discord for investigating the beginnings of some Forth-like implementations in other languages.

We’ve begun with a simple, incomplete implementation in Python which is less than 60 lines of Python code. simple.py

Building on that, there are simple implementations of

a word dictionary that mimics the RAM layout of earlier Forths, fram.py
forth-like variables, fvars.py
to come: simple implementation of a forth-like compiler that creates threaded code.

In addition to the sample implementation code, we’ve begun

creating documentation meant to help understand the internals, in course/*
experimentation with outré avenues of discovery, eg. bolting ASON Altscript atoms into forth-ish, writing a portable, meta-language, very-higher-level version of the code which emits code in existing languages (i.e. VHLL -> Python), working, but, not as yet released on github
several snapshot video vignettes organized as a playlist

Anyone and everyone is invited to join the discord, kibbitz, ask questions and show off implementations in other languages.
