Question

I’m new to Clojure and I’m wanting to use Clojure core.match:
https://github.com/clojure/core.match

I’ve setup my project with TextMate using the following bundle: https://github.com/swannodette/textmate-clojure

My project.clj is as follows:

(defproject Prototype "0.0.1-SNAPSHOT"
  :description "Prototype ARS Implementation"
  :dependencies [[clojure "1.3.0"] [org.clojure/core.match "0.2.0-alpha6"]])

In terminal, I executed:

cake deps

Which downloaded the correct version of Clojure and the Clojure.core.match jar files.
Now I’m editing my ‘src/Prototype/core.clj’ and I’m wanting to use the match functionality.

I’ve tried using both the provided code on the GitHub page:

;; when using HEAD
(use '[clojure.core.match :only [match]])

;; when using the latest released alpha
(use '[clojure.core.match.core :only [match]])

This is my current code:

(ns Prototype.core
  (use '[clojure.core.match.core :only [match]]))

(println
  (let [x [1 2]]
    (match [x]
      [[1 2]] "It worked!"
      :else "It failed!")))

When I load the file into the cake repl; I get the following error:

lib names inside prefix lists must not contain periods

Any ideas?
Cheers.

(ns Prototype.core
  (:use [clojure.core.match.core :only [match]]))

(println
  (let [x [1 2]]
    (match [x]
      [[1 2]] "It worked!"
      :else "It failed!")))

There’s no need to quote in the ns form.

(I’ve assumed clojure.core.match.core was the correct namespace. If it doesn’t work use clojure.core.match instead.)
