Hi, there. I have just started playing with Racket and would like some help
with using streams/generators (I am not particularly versed in programming in a
functional style and am attempting to learn :-))
So I have a function called (new-name) that creates a random name, like "Bob
Brown" or "Jill Xi". It looks something like
(define (new-name ethnicity sex)
; return a string like "First LAST" based on ethnicity and sex)
This is all good and dandy and works well. What I would like to do now is
something like
(define name-gen
(infinite-generator
(yield (new-name ethnicity sex)))) ; won't work...
(get-some-names (name-gen "anglo" "male") 10) ; not sure about this...
Which would, from a generated list or stream, return ten names. I can do this
using something like
(for/list ([i 10])
(new-name "anglo" "male"))
but that seems to miss out on the goodness of streams/generators.
Any help/tips appreciated.
TIA, .. mark.
