In the effort to design "hands on" newLISP web demonstrations, here's "WebLisp.net - An Online Interpreter for the WebLisp Programming Language"
http://weblisp.net/
And for Weblisp's efforts, the requisite reddit Lisp/Scheme naysayers ;)
http://www.reddit.com/r/programming/com ... e_weblisp/
The interesting thing with the Weblisp demo, is the "canvas" tab...
Highlight the left edit area and delete. Click the "canvas" tab, scroll down and copy the code (below e.g.) over to the left edit area and click "run program".

Great.
Here is one program for Weblisp.
Code: Select all
(gfx-reset)
(define (P a b r)
(gfx-line a b r r)
(gfx-line a b r (- 100 r))
(gfx-line a b (- 100 r) r)
(gfx-line a b (- 100 r) (- 100 r)))
(define (Q r)
(P 0 0 r)
(P 0 100 r)
(P 100 0 r)
(P 100 100 r))
(define (drawy r)
(if (> r 0)
(begin (Q r)
(drawy (- r 2)))))
(drawy 50)
The result is on canvas.

great work! It's really clever.
Looks like newLISP has got some serious competition... :)

Two interesting canvases.
1.
2.
Code: Select all
(gfx-reset)
(define (P a b r)
(gfx-line a b r r)
(gfx-line a b r (- 100 r))
(gfx-line a b (- 100 r) r)
(gfx-line a b (- 100 r) (- 100 r)))
(define (Q r)
(P 0 0 r)
(P 0 5000 r)
(P 100 0 r)
(P 100 5000 r))
(define (drawy r)
(if (> r 0)
(begin (Q r)
(drawy (- r 1.01)))))
(drawy 50)
Code: Select all
(gfx-reset)
(define (P a b r)
(gfx-line a b r r)
(gfx-line a b r (- 100 r))
(gfx-line a b (- 100 r) r)
(gfx-line a b (- 100 r) (- 100 r)))
(define (Q r)
(P 0 0 r)
(P 0 5000 r)
(P 5000 0 r)
(P 5000 5000 r))
(define (drawy r)
(if (> r 0)
(begin (Q r)
(drawy (- r 1.33333)))))
(drawy 50)

Nice pictures, Kazimir! I love this algorithmic-drawing stuff - there's a lot of good stuff out there too:

xytroxon,
where is it evaluated, on your server on on my client, I missed that piece of information.

Thanx cormullion, amazing site on the link you posted (for those who didn't noticed, follow the first link in that blog. )

Everybody interested to make Art in newLISP should also go here:
http://www.newlisp.org/index.cgi?Postscript
also linked from:
http://www.newlisp.org/index.cgi?Art
The advantage of the Postscript approach is, that graphics and files created are scalable vector graphics.
On Mac OS X you are ready to go with the postscript module. On Win32 or Linux, you also have to install a postscript viewer, i.e. Ghostscript.
Here is one of the pictures similar to the stuff at the
www.azarask.in site:

and here the source:

Here is Christoph Dietze's post on his weblisp at Google Web Tools:
An Interpreter running inside the Browser using GWT
Hello,
I just put the first version of a project online. Since it heavily
relies on GWT and uses it to do some advanced stuff, I thought it is
worth to put up a post about it here.
It is an interpreter that runs completely inside the browser. The
language that it interprets is a
new LISP dialect that I created for
it, called WebLisp. It is a functional and imperative programming
language. There is also some documentation about it on the site.
If you're interested, you can find it here:
http://weblisp.net
Enjoy,
Christoph
So it is a "new LISP" and not "newLISP" :(

And for others interest,
Kazimir's weblisp post...

Although I use PostScript (and newLISP) a lot (eg
here ), I'm still fascinated by the idea of higher-level (more coordinate-free...) type of computer art, where you just sort of set a few things up and watch what unfolds. The algorithmic art procedures are short and simple - and interactive too - one day there will be a newLISP one, perhaps, but not just yet!
