小马将过河
正如站点介绍Clojure(Script)'s missing piece
使用示例
(require '[com.rpl.specter :refer :all])
;;; 1.1 clojure
(map inc [1 2 3 4])
(into #{} (map inc #{1 2 3 4}))
;;; 1.2 specter
(transform ALL inc #{1 2 3 4} )
(transform ALL inc '(1 2 3 4))
;;; 2 方便的操作嵌套数据结构
;;; 2.1 Clojure
(defn apply-fn-to-map [f m]
(into {}
(for [[k v] m]
[k (f v)]) ))
(apply-fn-to-map inc {:a 1 :b 2})
(map #(apply-fn-to-map inc %) [{:a 1 :b 1} {:c 1 :d 1}])
;;; 2.2 Specter
(transform [MAP-VALS] inc {:a 1 :b 2})
(transform [ALL MAP-VALS] inc [{:a 1 :b 1} {:c 1 :d 1}] )
(transform [ALL MAP-VALS even?] inc [{:a 1 :b 2} {:c 3 :d 4}] )
(transform [MAP-VALS MAP-VALS] inc {:a {:aa 1} :b {:ba -1 :bb 2}}) => {:a {:aa 2}, :b {:ba 0, :bb 3}}
;;; 工作原理
[{:a 1 :b 2} {:c 3 :d 4}]
;;; ALL
{:a 1 :b 2}
{:c 3 :d 4}
;;; MAP-VAL
1
2
3
4
;;; even?
2

;;; inc

;;; 重建
;;; reverse even?

5
;;; reverse MAP-VAL
{:a 1 :b 3}
{:c 3 :d 5}
;;; reverse ALL
[{:a 1 :b 3} {:c 3 :d 5}]
;;; 业务使用
