Hi,
I just wanted to know how to handle functions parameters in newLisp, in particular those ones (I only saw optionnal parameters in the docs):
- rest parameters;
- keyword parameters;
Thanks.
&rest and &optional like CL could used like (args) in newlisp like (define (foo a b) (args)) but you have to build around it al ittle yourself..
You can implement named parameters this way:
(local (len width height)
(bind (args) true)
(println "len: " len " width:" width " height:" height)
))
(foo (width (+ 15 5)) (height 30) (len 10))
; this prints
len: 10 width:20 height:30
Arguments are evaluated and assigned to the local variables.
Very elegant solution.
Thanks for all your replies,
Do you think such a markup langage //http://www.nongnu.org/skribilo/ can be implemented in newLisp? In fact, that's what I want to do as a first project (with less features), but maybe I'm too pretentious/ambitious.
I often ask for named parameters too :-) (//http://www.alh.net/newlisp/phpbb/viewtopic.php?t=2180) There are many ways of implementing it - I just usually forget them when I need them...
skribilo looks interesting - but a substantial project too.

(local (len width height)
(bind (args) true)
(println "len: " len " width:" width " height:" height)
))
(foo (width (+ 15 5)) (height 30) (len 10))
; this prints
len: 10 width:20 height:30

Lutz, could you add this to "Code Patterns" section 4. Local variables?
