Whither newLISP? / Is true symbol?
June 24, 2014, 10:34:12 PM
> (symbol? 'true)

true

> (symbol? (eval 'true))

nil

> (= 'true (eval 'true))

true



Is it bug or feature? I'd expect that true is always symbol.

Whither newLISP? / Proposal: forever & doforever
September 01, 2011, 01:56:04 AM
(forever ...) := (while true ...)

(doforever(i) ...) := (begin (setf i 0)(while true (++ i) ...)).



Probably (dotimes(i 9223372036854775807)...) is good enough for doforever.

Whither newLISP? / Why do you use sym?
July 03, 2011, 05:17:19 PM
I'm trying to make review of situations where sym is useful. I use it


[*]for generation of expressions processed by programs. For example, here:

http://kazimirmajorinc.blogspot.com/2011/01/enumeration-of-lambda-expressions.html">http://kazimirmajorinc.blogspot.com/201 ... sions.html">http://kazimirmajorinc.blogspot.com/2011/01/enumeration-of-lambda-expressions.html


  • [*]for alpha-conversion, i.e. prevention of symbol clashes when calling macros. It is equivalent of use of (gensym) in other Lisp dialects in macro definition. For example, here

    http://kazimirmajorinc.blogspot.com/2009/12/symbols-as-sexprs.html">http://kazimirmajorinc.blogspot.com/200 ... exprs.html">http://kazimirmajorinc.blogspot.com/2009/12/symbols-as-sexprs.html



  • [*]for bulk definitions of functions or macros using same algorithm, for example, defining operators setq+, setq-, setq* ... such that (setq+ a b) <=> (setq a (+ a b)),  (setq- a b) <=> (setq a (- a b)) ... For example, here

  • [*]for simulation of hash tables - in some other language, I'd use B["011101"], in Newlisp I just use symbol B011101.  For example, here

    Do you have some other example of use of sym?

    So, what can you actually DO with newLISP? / K. Majorinc, Newlisp related presentation in Zagreb, Croatia
    June 01, 2011, 03:46:01 AM
    I announce my presentation at Sunday, 5. June 2011, 18h, http://hackerspaces.org/wiki/Hacklab_in_mama">Hacklab "mama", Preradoviceva 18, Zagreb.

    with topic



    [size=110]The program that calculates the tangent on the graph of the function in Newlisp as example of "code is data" approach in Lisp. [/size]



    Very elementary, classical Lisp example with few Newlisp specificities, suitable for those who want to familiarize with or rethink basic Lisp ideas.

    Whither newLISP? / (setf)
    April 21, 2011, 07:35:06 PM
    Currently:


    Code Select
    > (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 and speed improvement as well. Same for (set) and (setq).

    Whither newLISP? / Two small design issues
    March 23, 2011, 01:42:05 PM
    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 binding is dynamic as well) and it would make the feature more orthogonal. Constant already works in form (constant '<variable name>).



    Second - extending set so it can be applied on "implicit indexing". If



    (set 'X 5) = (setf X 5)



    then why not



    (set '(L 1) 5) = (setf (L 1) 5)?

    Whither newLISP? / Least common multiple?
    March 11, 2011, 12:15:21 PM
    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 found their way to Newlisp?

    Whither newLISP? / Is there anything like reader-macros in Newlisp?
    March 04, 2011, 06:10:45 AM
    I remember that Ted once proposed it, but I do not remember if it was implemented on any way.

    Whither newLISP? / Proposal: extending user defined eval on implicit evaluation
    February 16, 2011, 08:43:21 PM
    Currently, user defined eval is limited on explicit occurences:


    Code Select
    (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 original-eval, not eval

    Although this example only show need for such eval on top level, it is simplified example; redefined eval should replace all implicit calls of eval. Why not using explicit eval everywhere where it is needed? Because code would explode to something like


    Code Select
    ((eval 'setf) (eval 'f) (eval '(lambda(x)((eval '+) (eval 'x) (eval '2))))
    ((eval 'f) (eval '4)).

    Not impossible, but troublesome.

    So, what can you actually DO with newLISP? / Unbalanced Parentheses discontinued.
    February 05, 2011, 01:48:28 AM
    Starting from last week, Cormullion does not publish his "Unbalanced parentheses" site any more. I am bit sad about that, because it was certainly one of the best Newlisp sites out there; and I hope that he'll republish his materials again in some future. His http://newlisper.blogspot.com">old blog is still available.



    Any case, thanx, Cormullion.
