Las Brinkhoff hat seinem emacs Forth beigebracht. Klar, Linux-Welt...

Features in progress:
Recognises definitions and moves by balanced expressions.
Interact with a Forth session: enter commands, load files, evalutate expressions.
Display stack comment when moving the cursor over a word.
Edit block files.
Tab completion.
Query a running Forth about words, search order, etc.

Hab es nicht ausprobiert, aber klingt interessant.
