RABL

RABL (Ruby API Builder Language) is a Rails and Padrino ruby templating system for generating JSON, XML, MessagePack, PList and BSON. When using the ActiveRecord 'to_json' method, I find myself wanting a more expressive and powerful solution for generating APIs. This is especially true when the JSON representation is complex or doesn't match the exact schema defined within the database. General ruby templating with json, bson, xml, plist and msgpack support.
