Question

In clojure, how do I read a file into a sequence where each line is one element in the sequence. So I’d like to see the definition of the function get-lines so I could do the following:

(def lines (get-lines "test.txt"))

and lines is a non-lazy sequence.

Answer 1

To convert lazy sequence to non-lazy you can use doall like so:

(use 'clojure.java.io)

(defn get-lines [fname]
  (with-open [r (reader fname)]
    (doall (line-seq r))))
