I have a nested map which looks something like this:
{"a" {:points 2} "b" {:points 7} "c" {:points 1} "d" {:points 3}}
And I would like to turn it into a sequence of a maps in order to sort (with sort-by) and print it afterwards.
({:name "a" :points 2}
{:name "b" :points 7}
{:name "c" :points 1}
{:name "d" :points 3})
From the documentation I figured that I will need something like postwalk but I can't wrap my head around it.
(sort-by :name
(map #(conj {:name (key %)}
(val %))
{"a" {:points 2}
"b" {:points 7}
"c" {:points 1}
"d" {:points 3}}))
-> ({:points 2, :name "a"}
{:points 7, :name "b"}
{:points 1, :name "c"}
{:points 3, :name "d"})
If your goal is to print it in sorted order, why not simply put it into a sorted map? (into (sorted-map) m).
I'd suggest something like:
(sort-by :name
(for [[n m] my-map]
(into m {:name n})))
This makes use of a few handy techniques:
