Re: Idiomatic way to reference a bundled data file from Clojure source?
The idiomatic way may be to include the file(s) in the classpath and there is already a `resource` function in clojure.java.io that can load it from the classpath: $ lein new foo $ cd foo $ mkdir resources $ catresources/test.txt hello world foo bar ^D $ # edit src/foo/core.clj as follows (ns foo.core (:require [clojure.java.io :as jio])) (println (slurp (jio/resource test.txt))) $ lein deps $ lein repl user= (require 'foo.core) hello world foo bar user= Regards, Shantanu On Jun 29, 5:02 am, stu stuart.hungerf...@gmail.com wrote: On Jun 29, 12:17 pm, Stephen C.

Idiomatic way to reference a bundled data file from Clojure source?
Hi, I'd like to bundle a collection of (JSON) datafiles with a Clojure project source tree so that Clojure functions can reliably find and open those datafiles. What's the idiomatic way of going about this? In the past with other languages I've used tricks like Ruby's .dirname(__FILE__)/... construct but this kind of approach doesn't seem a good fit for Clojure or for the JVM facilities it provides. Can anyone point to a Clojure project that does this well? Thanks, Stu -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Idiomatic way to reference a bundled data file from Clojure source?
Hey, I don't have a good example, but the right way to do is with resources which are basically just files that live on the classpath: * Put the files in a folder on your classpath. If your using leiningen, the resources/ directory does this by default. * Get a URL to the file with clojure.java.io/resource. If your file is root/resources/my-project/my-resource.txt, you'd use (resource my-project/my-resource.txt). * Read the contents of the file by passing the resource URL to clojure.java.io/reader or one of its friends. When you jar up your app the resource files will be included in the jar and just work. Hope this helps.

Re: Idiomatic way to reference a bundled data file from Clojure source?
I'd like to bundle a collection of (JSON) datafiles with a Clojure project source tree so that Clojure functions can reliably find and open those datafiles. What's the idiomatic way of going about this? One idiomatic way to do this in Clojure is: - store the files within a directory named resources at the top level of your project folder, - arrange for that folder to be in your classpath at runtime, - obtain a reference to the files at runtime using .getResource with a relative path. If you use lieningen, the resources folder will be in your class path automatically and the files/directories it contains will be copied to the top level of your jar file if you make one. Here's an example: (defn resource [path] (when path (- (Thread/currentThread) .getContextClassLoader (.getResource path (require '[clojure.java.io :as io]) (slurp (io/file (resource js/boo.js))) I did this in a leiningen project called scratch. It returned the contents of the file scratch/resources/js/boo.js because scratch/resources was on the classpath.
