Why do I get an error when I run (use 'clojure.contrib.repl-utils)?

Question

I found that I can use Chris Houser\'s repl-utils library (clojure.contrib.repl-utils/source or show) for poking into Java by reading Programming Clojure book page 20.

Answer 1

it works for me, we need more information to help you: what happend exactly when you run it? does it raise an error?

Answer 2

FOUND A SOLUTION

I asked and got some answers.

In short, - it's OK to have it require, but gives me an error to refer. As a result, I need to use as follows

user=> (require 'clojure.contrib.repl-utils)
user=> (clojure.contrib.repl-utils/expression-info '(+ 1 2))
{:class java.lang.Number, :primitive? false}
