I announce my presentation at Sunday, 5. June 2011, 18h, Hacklab "mama" , Preradoviceva 18, Zagreb. with topic The program that calculates the tangent on the graph of the function in Newlisp as example of " code is data " approach in Lisp. Very elementary, classical Lisp example with few Newlisp spe...

John Shutt is author of Kernel, experimental Lisp dialect that attempts to combine fexprs with lexical scope.

Great! If you're in Croatia, you'll probably visit Zagreb, and I'll be glad to drink some beer with colleague. If you'll have free evening and will, we might arrange some (your) lecture or presentation of your work on NL or anything related to computers in Hacklab and then go to some beer ... I'm lo...

Without using contexts, demonstrated by johu, if you want pass by reference , you should really pass the reference of the structure (not the structure itself), and make your function dereference it: (set 'x '(0 1 2 (3 4))) (define (destruct lst) (setf ( (eval lst) 3 0 0) 1)) ; eval is dereference (p...

It works for local variables

> (let((x 1))(setf x 7)(* 2 x))

> (local(x)(setf x 8)(+ x 1))

What exactly do you dislike?

In Common Lisp? Something like that: (defmacro until (test &body body) (let ((start-tag (gensym "START")) (end-tag (gensym "END"))) `(progn (setf $idx 0) (tagbody ,start-tag (when ,test (go ,end-tag)) (progn ,@body) (incf $idx) (go ,start-tag) ,end-tag)))) (until(= (setf x (random 10)) 0) (format t ...

Currently: > (setf) ERR: missing argument in function setf It would be consistent with existing possibility of (setf x 1 y 2 ...) and analogous to (let()...) and (expand '(x y) '()) to allow (setf) as legal. I didn't seen implementation of setf , but I guess that it might result in very small size a...

(eval (setf code '(when (< counter 40) (inc counter) (println counter) (eval code)))) or even better, "crawler-tractor" (set 'f (lambda() (if (< counter2 50) (begin (println "Hi for the " (inc counter2) ". time. ") (push (last f) f -1) (if (> (length f) 3) (pop f 1)))))) (f) This last is particular...

I'm enjoying it!
But I have a feeling that my wife will put the veto in few minutes.

Intelligence agency informed me that kosh implemented one lcm : https://gist.github.com/897015

Additionally, if you insist on minimal syntax, you can play with fexprs (macros). (setf [print.supressed] true [println.supressed] true) ; ---- (load "http://instprog.com/Instprog.default-library.lsp") ; only println= used (setf [print.supressed] nil [println.supressed] nil) ; ---- (define-macro (fl...

Yes it is even better.
I have 1900x1200.

I like the concept, It seems very practical.
This is how it looks on my computer.
Perhaps you can pack upper part even denser.

Yes, it was that.
If it was turned off because of efficiency issues, OK, since it is really minor issue.

I see two possibilities for small design improvement, worth only if implementation is simple and there is little loss of speed. First - extending constant so it works on local bindings as well. It is less probable that one need it, however, it is not completely impossible (especially because local b...

(eval (extend '(map append) (map quote '(("one" "two")("for" "you")))))
(map (fn(x)(apply append x)) (transpose '(("one" "two")("for" "you"))))

It appears that Newlisp doesn't have least common multiple , right? If not, I propose the addition (with name lcm ), at least because of symmetry: its "pair", gcd is already here - alone. Btw, support for real numbers is impressive: beta, gamma, erf, Fourier's transformation. How these functions fou...

I remember that Ted once proposed it, but I do not remember if it was implemented on any way.

Currently, user defined eval is limited on explicit occurences: (setf original-eval eval) (constant 'eval (lambda(x)(inc eval-counter) (print eval-counter ": " x "=>") (println (original-eval x)))) (eval '((lambda(x)(+ x 2)) 3)); works OK ; main program (setf f (lambda(x)(+ x 2))) (f 4) ; used origi...

Hi, Michael. Yes, I prefer serifs, although I admit that sans serifs are more readable on screen, but if I need that I use Arial. I also like Art Nouveau fonts. What are your favourite fonts? I abandoned vehement photo because I've read somewhere that readers are less likely to return to site if the...
