# six-degrees

Implementation of [Six Degrees](http://www.puzzlenode.com/puzzles/14-six-degrees-of-separation) using Neo4J.

## Ruby and Bundler

This project is written in Ruby and uses Bundler.

Prefix any commands with `bundle exec`.

Pry is also supported, including a `.pryrc` file so that everything is loaded up startup of Pry.

## Neo4J

Neo4J is assumed to be running on the standard port.

There are Rake tasks provided to install and control the Neo4J process, but I haven't gotten them working.

Success has been had with neo4j installed using Homebrew, and started thusly:

    brew install neo4j

    neo4j start

Using this method, you can use the [local Neo4J console](http://localhost::7474/) to inspect the dataset and try writing queries.

The project uses `Neo4J::ActiveNode` to implement an ActiveRecord-like pattern for the two model objects, and they

set up all relationships.

## Rake tasks

The functionality is exposed through Rake tasks.

    rake sixd:clear           # Clear out the database (get rid of data from previous runs)

    rake sixd:load            # Load complex_input.txt into the Neo4J database

    rake sixd:connections     # Print the connections for each User
