Clojure：包装集合中每个元素的惯用方式

Question

If I have a collection of a particular shape: 如果我有特定形状的集合：

["Alpha", "Beta", "Gamma"]  ;; vector of strings

and I want to transform it by wrapping each element: 我想通过包装每个元素来对其进行转换：

[{:name "Alpha"}, {:name "Beta"}, {:name "Gamma"}]

Is there a better way to express that than this rather kludgy map ? 有比这张模糊的map更好的表达方式吗？

(map #(identity {:name %}) coll)

Answer 1

If you don't like map with (fn [v] {:name v}) you can use for : 如果您不喜欢使用(fn [v] {:name v}) map ，则可以for ：

(for [v coll] {:name v})
;; => ({:name "Alpha"} {:name "Beta"} {:name "Gamma"})

Answer 2

You could simply use fn : 您可以简单地使用fn ：

(map (fn [v] {:name v}) coll)

if you want to use the anonymous function syntax you can use array-map to construct the map: 如果要使用匿名函数语法，则可以使用array-map构造映射：

(map #(array-map :name %) coll)
