Re: Properly including clojure-contrib
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")) On Thu, Jun 16, 2011 at 5:37 PM, octopusgrabbus wrote: > I don't know what I'm doing wrong.

Re: Properly including clojure-contrib
Hi cmn, A few things: 1. The warnings you see are because the clojure.contrib.string namespace defines several functions that have the same name as core functions (repeat, reverse, etc.). The recommended way to pull in namespaces like that is to do (:require [clojure.contrib.string :as str]), and then the functions can be used via (str/repeat ...), (str/reverse ...), etc. 2. As of 1.2, "split" is incorporated into clojure.string, so no need to grab clojure.contrib.string just for that function. clojure.string also defines functions with the same name as core functions, so it should be pulled in via (:require [clojure.string :as str]), and split can then be used via (str/split ...). 3. That EOF error is because process-file needs one more closing paren. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

I don't know what I'm doing wrong.

Re: Properly including clojure-contrib
Hi cmn, I think if you add clojure.contrib.string to your use or simply add (:use clojure.contrib.string). I think that should fix it.
