Overview

LibaryEvalContext constructs an instance of an anonymous class that library files will be instance_exec’d against.

The anonymous class ensures that ‘Inspec.resource(1)` will return an anonymouse class that is suitable as the parent class of an inspec resource. The class returned will have the resource registry used by all dsl methods bound to the resource registry passed into the #create constructor.
