Atpruby

Ruby wrap for working with Jeff Sackmann's tennis_atp database. You can set it up in Postgres by cloning this fork and running bash setup/PostgreSQL/convert_postgres.sh. More instructions for doing that are here.

Once you've done that, use this gem to write ruby scripts to query the DB.

Add this line to your application's Gemfile:

gem 'atpruby'

And then execute:

$ bundle

Or install it yourself as:

$ gem install atpruby
