Hi!

Version 2 of "UF", a traditional Forth for Uxn has been released:

    http://www.call-with-current-continuation.org/uf/uf.html

Several minor bugs have been fixed and some small improvements
been made.

(This announcement is mostly intended to emphasize that
UF is actively maintained, so further releases will not be mentioned
here in the future)


cheers,
felix

Awesome! I am working on learning uf almost every day. Forth, uxn, and 
this sort of asm programming are relatively new to me, but I am actively 
very interested in this project

I love the improvements! The kernel is some of the nicest uxntal code
I've ever seen.

I love that the snarf word is now exposed in WORDS. I was wondering if
you had an idea about how multi-line pastes should be handled? Right
now it pastes an unknown character, which breaks evaluation a bit.

UF2 is wonderful <3

Hi all -- trying to read a large file with  4000 dup 1000 fileread 
and it's alright, but 4000 dup 2000 fileread causes a stack underflow. 
Any idea why?

Hm... I can't reproduce this. Why "4000", actually? It will read 2000
bytes at address 4000 which may overwrite parts of the forth code.
Is this really what you attempted?

Multiline snarf/yank is not supported yet, but will be added in the next version.

Sure, I just want to spam this list with useless news.

Consider it done.

It's not useless news.

I was just think that I should mention this so anyone else also
learning uxntal could see this, but:

When you do #0000 STH2, you could as well do LIT2r 0000, to push that
literal directly to the return stack. UF2 has 2 instances where lits
could be written directly in their stack.

It's a neat little optimization to know.

Clever indeed - thanks for the tip!
