# 4clojure.com has been discontinued

Another site may take over the domain name at some point, but for now 4clojure.com is down on purpose. [More details on the forum](https://groups.google.com/g/clojure/c/ZWmDEzvn-Js).

# 4Clojure

An interactive problem website for learning Clojure:

[https://www.4clojure.com](https://www.4clojure.com).

## Contributing

Anyone interested in contributing should check out

the [Issues](https://github.com/4clojure/4clojure/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](https://github.com/technomancy/leiningen).

* Download and install [mongodb](http://www.mongodb.org/).

* The project uses

[clojail](https://github.com/flatland/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`

* To run the tests: `lein test`
