Why doesn’t someone port gForth or some subset of it to iOS ? I realize there is a “sort of” forth-like application called retro but it is a very poor version and to tell the truth, I can’t make it do much of anything useful. Worst of all, it does’t really execute statements on the fly the way it is advertised to do. Obviously it is possible to write interpreters under iOS nowadays since there are many versions of python, not to mention J, out there for the taking.
A good forth needs to either have a specialized keyboard with some extra keys and some stack viewing functionality. I even tried carrying around a raspberry pi for my iPad so I could run forth, but that still doesn’t make up for the necessity of having to switch between numeric, character and special symbol keyboards all the time.
