An interpreter for the algoritmic language Scheme, a dialect of LISP
developed at MIT. Siod is a C implementation that covers a large part
of the standard and can be run with a small amount of memory.
It is the ideal tool to learn the language or for experimenting with
functional languages.
You are a student/teacher and want to run SCHEME on your powerUP (TM)
board ? Now you can do it... 8-)
I just did this port (original source and 68k version:
dev/lang/siod.lha) mainly for fun, but it actually does
make some sense, too. For example, if you like to calc the
Ackermann() function you'd better use the PPC... ;-)
Get Abelson/Sussmanns "Structure and Interpretation of Computer Programs"
and learn implementing lists, streams, stacks, register machines, ...
An example for the power of Scheme ?
Here's a short merge sort (taken from the samples directory):
(define (merge-list x y)
(cond ((null? x) y)
((null? y) x)
(else (if (test (car x) (car y))
(cons (car x) (merge-list (cdr x) y))
(cons (car y) (merge-list x (cdr y)))))))
(define (merge-sort x)
(if (null? x)
nil
(do ((ptr1 x (cdr ptr1))
(ptr2 (cdr x) (cdr ptr2)))
((or (null? ptr2)
(not (test (car x) (car ptr2))))
(set-cdr! ptr1 nil)
(merge-list x (merge-sort ptr2))))))
Call "start.bat" from inside this directory to start the
interpreter and set up its initial environment.
Enjoy playing around with it.
