running command when lein repl starts

[Andy Smith]

Hi,

How can I get a command such as '(use 'clojure.math.numeric-tower)' to run when I start the repl with 'lein repl' ? I currently have my leiningen project setup as the following :

(defproject test "1.0.0-SNAPSHOT"
  :description "FIXME: write description"
  :dependencies [[org.clojure/clojure "1.3.0"]
                 [org.clojure/math.numeric-tower "0.0.2"]])
  :repl-options {
                 :dependencies [
                 [org.clojure/math.numeric-tower "0.0.2"]]
                 :init (clojure.core/use 'clojure.math.numeric-tower)}



and the error I get is as follows :


andy@Aspire-V3-571:~/projects/clojure/test$ lein repl

What am I doing wrong? Thanks in advance.

Is it intentional that you are using clojure 1.3.0 instead of a newer version like 1.5.1 ?

Do  "lein deps"   to download the dependencies. 

Then do lein repl

Ok valid point, but I still get the same kind of errors?

[David Powell]

Hmm, maybe you need to use this:

Hmm, no it is just a syntax thing with your project, This works:

(defproject test "1.0.0-SNAPSHOT"

  :description "FIXME: write description"

  :dependencies [[org.clojure/clojure "1.5.1"]

                 [org.clojure/math.numeric-tower "0.0.2"]]

  :repl-options {:init (use 'clojure.math.numeric-tower)}

)

You had closed the opening paren on the :dependencies line.  And :dependencies isn't allowed inside :repl-options, which was causing the org.clojure error.

yes, Ive seen that but it doesnt seem to help me greatly. Just out of curiosity how do you generally setup your repl so it already includes these kind of common libraries? I dont really want to be typing lots of 'use' commands into the repl every time i start it. Is using leiningen the wrong way to do this?

[David Powell]

I tend to work on files in emacs or an IDE, with a linked repl, rather than at a raw repl, so the file I'm working on will tend to have an ns directive that will require the appropriate namespaces, so I just eval that when I open the file.

oops, you are right but if I paste into my project.clj I get a different error when I run lein repl
