Ruby Roy is a bridge to the offical Roy compiler.
Roy.compile File.read("script.roy")
gem install roy-lang
This library includes a copy of the Roy source code, updated as each offical version of Roy is released.
The json library is also required but is not explicitly stated as a
gem dependency. If you're on Ruby 1.8 you'll need to install the
json or json_pure gem. On Ruby 1.9, json is included in the
standard library.
The ExecJS library is used to automatically choose the best JavaScript engine for your platform. Check out its README for a complete list of supported engines.
