Whither newLISP? / Re: In-place parameter substitution
April 13, 2012, 11:49:26 PM
Quote from: "Kazimir Majorinc"How about this one for beginning:



(define-macro (my-inc p0)(set p0 (+ (eval p0) 1)))

The above fails with the following error when called through my sum function above:

ERR: symbol expected in function set : p0



What I'm interested is having a function/macro/fexpr that can modify its arguments in-place, exactly like what inc does: i.e., it works even with literal numbers. Is this possible or do built-ins like inc and dec can only be implemented by the underlaying newLISP C implementation?

Let me clarify my question:



Is it possible to create my version of inc, my-inc?


Code Select

(define (sum (x 0)) (my-inc 0 x))
(sum 1) ;=> 1
(sum 2) ;=> 3
sum ;=> (lambda ((x 0)) (my-inc 3 x))

My gut instinct tells me in order to have a self-modifying code like the above, my-inc must have a reference to the enclosing lambda list. How do I go about creating my-inc ? Is this possible?

Hi, is it possible to create a user-defined function much like what inc does: in-place parameter substitution, or is this only available for built-in functions?



Where do newLISPers hangout? Is there a #newlisp IRC channel somewhere?

newLISP in the real world / Integer comparison bug

Loving the language so far.


Code Select

(= 9223372036854775807 9223372036854775808)

The above returns true. Shouldn't it be nil instead? Where can I submit bug reports? Do we have an bug tracker?
