Hi, given a vector of the form
[:key1 1 2 3 :key2 4 :key3 5 6 7] I wand to create a map collecting the items behind each keyword as a vector like this: {:key1 [1 2 3] :key2 [4] :key3 [5 6 7]} I have already written two functions which achieve this, but neither of them "feels good" and I am interested in more elegant and idiomatic solutions. (defn keycollect-partition [coll] (->> coll (partition-by keyword?) ; bundle at key (partition 2) ; kw + its arg (map (fn [[[sec] arg]] [sec (vec arg)])) ; destruct the mess (into {}))) ; make it a map (defn keycollect-reduce [coll] (apply zipmap (reduce (fn [ac x] (if (keyword? x) [(conj (first ac) x) (conj (second ac) [])] (update-in ac [1 (dec (count (first ac)))] conj x))) [[] []] coll))) Added complexity: My original vector does not yet contain keywords, but I construct them in a map regexp-matching each item and creating a keyword from the first group of the match. Any pointers or ideas appreciated. Regards, Stefan -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
