传递参数的翻转顺序 [英] flip order of passed arguments

问题描述

是否有惯用的/内置的方式来翻转传递给Clojure中的函数的参数顺序？

Is there a idiomatic / built-in way to flip the argument order that is passed to a function in Clojure?

就像我在这里对a的定义那样辅助函数：

As I do here with the definition of a helper function:

(defn flip [f & xs]
   (apply f (reverse xs)))


(vector 1 2)       ; [1 2]
(flip vector 1 2)  ; [2 1]

推荐答案

我认为大多数时候都有意义创建稍后使用的翻转函数，因此函数的变化形式如下：

I think it makes sense most times to create a flipped function that you use later, so the variation on your function would be this:

(defn flip [f]
  (fn [& xs]
    (apply f (reverse xs))))
