clojure通过关键字按字母顺序对地图值进行排序

Question

How would I sort

{
 {:name "d" :id 2}
 {:name "f" :id 3}
 {:name "a" :id 1}
 {:name "z" :id 9}
}

Alphabetically by name? Like this:

{
 {:name "a" :id 1}
 {:name "d" :id 2}
 {:name "f" :id 3}
 {:name "z" :id 9}
}

Answer 1

When in doubt, be sure to look at the Clojure CheatSheet .

In this case just use sort-by

(def data
  [{:name "d" :id 2}
   {:name "f" :id 3}
   {:name "a" :id 1}
   {:name "z" :id 9}])

(sort-by :name data) => 
  ({:name "a", :id 1}
   {:name "d", :id 2}
   {:name "f", :id 3}
   {:name "z", :id 9})

Note that I had to fix your data to use square brackets [...]
