I'm doing some file streaming with a lazy list and I ran into a
problem where I had to process a whole chunk at a time, so I wrote
this function. Just posting to see if I'm reinventing something or if
it might be a good addition to contrib.
(defn in-smaller-lists [the-list smaller-list-size]
(lazy-seq (let
[[fnbr the-rest] (split-at smaller-list-size the-list)]
(if (first the-rest)
(cons fnbr (in-smaller-lists the-rest smaller-list-size))
(list fnbr))
)))
Example:
user=> (in-smaller-lists (range 11) 3)
((0 1 2) (3 4 5) (6 7 8) (9 10))
I do database work and this is very useful for processing a csv n rows
at a time.
