Installation

Add this line to your application's Gemfile:

gem 'blockgraph'

And then execute:

$ bundle

Or install it yourself as:

Usage

TODO: Write usage instructions here

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Testing

When you run rspec, you need to run neo4j test server(http://localhost:7475) in advance. Others are the same as normal rspec.
