Pacer is a JRuby library that enables very expressive graph traversals.

Please look at my Introducing Pacer post for a detailed introduction and explanation of how Pacer is at once similar to and quite different from Gremlin , the project that inspired it.

Until I write some documentation, you may find it helpful to refer to the following specs files as well:

• base_spec.rb
• route_operations_spec.rb
• paths_route_spec.rb
• vertices_route_spec.rb
