Hi Base,
It's useful to think of the "pattern" of loop/recur and then apply it
to your problem. I.e
(loop [-- initial bindings --]
(if --- terminating condition ---
---return result--- ; otherwise...
(do-stuff with bindings
(recur ---with new bindings---))))
A simple example first; find (gather all ints in a vector larger than
some given int...
(defn gather-ints
[x coll-ints]
(loop [s-ints (seq coll-ints) v-out []]
(if (nil? s-ints) v-out
(let [i (first s-ints)
v-out (if (> i x) (conj v-out i) v-out)]
(recur (next s-ints) v-out)))))
(gather-ints 3 [1 2 3 4 5 6])
=> [4 5 6]
Note that you can access all bindings in lexical scope, e.g x. Also
see how v-out is reused (like a variable, but its not - its just the
name rebound to a new value. We use seq of the collection which
returns either nil or a sequable to which you use next for the next
item. This is idiomatic for clojure for loop/recur.
Now for your problem;
(defn date-seq
[d1 d2]
(loop [b (-> d1 (.dayOfMonth)
(.withMinimumValue))
v-out [] ]
(if (time/before? b e)
(recur (.plusMonths b 1) (conj v-out b))
v-out)))
-Hth, Adrian.
