Overview

Can take in a string and an object and use the object for formatting string interpolations using tokens of form: attribute_name. This templating class does not understand nested structures, so input should be a flat object/hash in the form of key-value pairs. A benefit of using Objectable for resolution is that it can understand almost any type of object: Hash, Struct, OpenStruct, custom objects, etc. For more information see underlying libraries:
