State of the Art

This site is in a very early stage of development, so there is not a lot of polish yet. Anyone interested in contributing should check out the Issues page for ideas on what to work on.

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 java.security.AllPermission; };
  

  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:

    mongod
  

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

    ./load-data.sh
  

• Run lein ring server and the browser should open for you.

    lein ring server
