Anything else we might add? / implicit indexing beyond the list

June 06, 2005, 04:57:27 PM

Code Select Expand
> (set 'q '(a b))
(a b)
> (q 1)
b
> (q 2)
b

but from last call I expect "nil" or something similar.

Does I wrong?

I want a list where last few elements will be optional (all together).

Can I know (through one operator) is such element presents in list and (if present) got its value?

Thanks.

Anything else we might add? / return list from a function

June 04, 2005, 05:47:07 PM

Hello!

I'm new to lisp and newLisp - sorry if that's quite stupid ;)

Can I return a list from a function as element-by-element, without collecting it to the temporary variable? And is it have a sense?

To enumerate network interfaces I wrote such thing:

Code Select Expand
# analog to: /sbin/ifconfig|awk '/^[[:alpha:]]/{print $1}'
(define (if-list)
  (set 'iflist (list))
  (dolist (str (exec "/sbin/ifconfig"))
    (if (find "^[[:alpha:]][[:alnum:]]+" str 0)
      (set 'iflist (append iflist (list $0)))))
  iflist)

Can I somehow remove "iflist" from code?

Possible there is a better way for such tasks?
