An interactive problem website for learning Haskell 'by doing': http://www.4haskell.com. It's not ready yet but hopefully will be soon.

The project is a fork of 4Clojure.

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

• Download and install leiningen.

• Download and install mongodb.

• 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
  

• Evaluation is done with mueval-cloud service you need to point 4haskell to the mueval-cloud-master endpoint with field :eval-endpoint in resources/config.clj

• Run lein ring server

• To run the tests: lein test
