An interactive problem website for learning Clojure:


Anyone interested in contributing should check out the Issues page for ideas on what to work on.

Join us in #4clojure on freenode for help or discussion.

Setup instructions for running locally

  • Download and install leiningen.
  • Download and install mongodb.
  • The project uses clojail, which requires a security policy setup in your home directory (because Clojure's eval is unsafe if used improperly). Set up a file called .java.policy in your home directory. The contents should look vaguely like this:

    grant { permission; };

    but see the readme of that project for more details.

  • cd to the 4clojure project directory and run lein deps.

  • Start up your mongodb, if you don't have autostart:

  • For the first time use, you will need to load the problem data. Run the script

  • Run lein ring server

  • To run the tests: lein test
