Re: help extracting number from string

[Joe Bogner]

This is probably better:

: (extract format (split (mapcar format (chop "35fabc79")) NIL))
-> (35 79)

 Having said that I seem to have got close by accident...i.e. I was
 going to try and bend this...but it found a single integer as it was :)

 : (pick '((Ch) (and (= Ch (uppc Ch)) Ch)) (chop 'ab33Cd))
 -> "3"

 I'd like this to detect 33 but see that chop precludes this.

 Any help much appreciated.

OK, how about this this?

: (mapcar format (extract pack (split (mapcar format (chop "35fabc79"))
NIL)))
-> (35 79)

: (mapcar format (extract pack (split (mapcar format (chop "35f79")) NIL)))
-> (35 79)

If i understood it correctly he wants to get all groups of number. "35f79"
-> (35  79)

[Joe Bogner]

how about

: (extract format (chop 'ab33Cd))
-> (3 3)

or

: (format (pack (extract format (chop 'ab33Cd
-> 33

I am just telling you pick can not help you here.
In this case just write a coroutine. You can handle different reading modes
(numbers vs strings) in there easily.

help extracting number from string

[dean]

I've seen num? and chop but think I need something in the middle to turn a
character to a number.

Having said that I seem to have got close by accident...i.e. I was going to
try and bend this...but it found a single integer as it was :)

: (pick '((Ch) (and (= Ch (uppc Ch)) Ch)) (chop 'ab33Cd))
-> "3"

I'd like this to detect 33 but see that chop precludes this.

Any help much appreciated.
