Forth

Wow, it's been a long time since I wrote a blog post. Sorry about the delay in finishing my Haskell state monad series; it's coming, I promise.

The reason for this post is that I stumbled upon a very cool free (and well-documented) interpreter for the Forth language written in x86 assembly language. That implementation, by Richard Jones, can be ( Read more... )

Here's another Forth I like: SOD32 at http://www.xs4all.nl/~lennartb/forth.html. Tasteful design, short, instructive. It uses a simulated processor instead of x86.

BTW were you at the last CRACL? I got there 30-40 minutes late and didn't find anyone.

Cool link, thanks.

No, I wasn't at the CRACL meeting. I keep meaning to come, but something keeps coming up.

I think it would be neat to have an emulator for the stack computers (Forth on a chip). Have you read Koopman's book?

I dipped into it last night. Someone actually made an fpga implementation of the SOD32 10 years ago, or rather some 16-bit variation on it -- I ran across that while searching for the link above.

I'll try to make it to the next meeting -- on time, this time. Haven't been to any of the recent ones.

check out Factor, factorcode.org

Did you know factor programming language. Factor is modern and *practical* forth and more additions. factor language has many powerfull features. http://factorcode.org

I do know Factor, though not all that well. It has some features I like and some I don't, but I agree that it's way more usable than raw Forth.

could you elaborate on the misfeatures? I really enjoy hearing about things that should have been done differently in programming languages.

Re: Did you know Factor mvanier June 28 2011, 03:33:16 UTC

To some extent, misfeatures are in the eye of the beholder. Anyway, I don't have time to discuss this right now, but maybe sometime in the future. Thanks for reading!

In case anyone is interested, here's a great article about Forth from a non-zealot point of view:
