I have the following data structure:
["a 1" "b 2" "c 3"]
How can I transform that into a hash-map?
I want the following data structure:
{:a 1 :b 2 :c 3}

1Please add the code you have tried and how it failed (e.g. errors, stacktraces, logs, ...) so we can improve on it.cfrick– cfrick2021-12-02 10:15:17 +00:00Commented Dec 2, 2021 at 10:15

1@cfrick Thanks for you suggestion. I did not have any meaningful code or errors to show. As I'm brand new to Clojure, my attempts were futile and would not add any meaningful value to the question—It would only have cluttered up the question with unnecessary verbiage. I opted for succinctness, for ease of reading and to respect peoples' time.leifericf– leifericf2021-12-02 11:37:00 +00:00Commented Dec 2, 2021 at 11:37

Use clojure.string/split and then use keyword and Integer/parseInt:
(->> ["a 1" "b 2" "c 3"]
(map #(clojure.string/split % #" "))
(map (fn [[k v]] [(keyword k) (Integer/parseInt v)]))
(into {}))
=> {:a 1, :b 2, :c 3}

and one more :)
(->> ["a 1" "b 2" "c 3"]
(clojure.pprint/cl-format nil "{~{:~a ~}}")
clojure.edn/read-string)
;;=> {:a 1, :b 2, :c 3}
Comments
(into {}
(map #(clojure.edn/read-string (str "[:" % "]")))
["a 1" "b 2" "c 3"])
;; => {:a 1, :b 2, :c 3}
Comments
(def x ["a 1" "b 2" "c 3"])
(clojure.edn/read-string (str "{:" (clojure.string/join " :" x) "}"))
;;=> {:a 1, :b 2, :c 3}
