在 Clojure 中将字符串向量转换为哈希映射

Question

我有以下数据结构：

["a 1" "b 2" "c 3"]

如何将其转换为哈希映射？

我想要以下数据结构：

{:a 1 :b 2 :c 3}

Answer 1

使用clojure.string/split and then use keyword和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}

Answer 2

(into {}
      (map #(clojure.edn/read-string (str "[:" % "]")))
      ["a 1" "b 2" "c 3"])
;; => {:a 1, :b 2, :c 3}

Answer 3

还有一个:)

(->> ["a 1" "b 2" "c 3"]
     (clojure.pprint/cl-format nil "{~{:~a ~}}")
     clojure.edn/read-string)

;;=> {:a 1, :b 2, :c 3}

Answer 4

(def x ["a 1" "b 2" "c 3"])

(clojure.edn/read-string (str "{:" (clojure.string/join " :" x) "}"))
;;=> {:a 1, :b 2, :c 3}
