How to repeat string n times in idiomatic clojure way?

Question

In Ruby, \"str\" * 3 will give you \"strstrstr\". In Clojure, the closest I can think of is (map (fn [n] \"str\") (range 3)) Is there a more idioma

Answer 1

You could also use the repeat function from clojure.contrib.string. If you add this to your namespace using require such as

(ns myns.core (:require [clojure.contrib.string :as str]))

then

(str/repeat 3 "hello")

will give you

"hellohellohello"
