The clojure.contrib.string namespace contains many function names which are
already defined clojure.core. So, by :use-ing clojure.contrib.string, you
will be replacing the core functions with the string functions. Rarely do
you really want to do this. It is generally best to :require instead of
:use.
so something like:
(ns test-csv
(:gen-class)
(:import (java.io BufferedReader FileReader StringReader))
(:use clojure-csv.core)
(:require [clojure.contrib.string :as string]))
(defn process-file [file-name]
(with-open [br (BufferedReader. (FileReader. file-name))]
(println (string/split (line-seq br)",")))
(defn -main [& args]
(process-file "resultset.csv"))
