Overview

This plugin reformats the lookup key according to a puppet's Hiera system, so instead of looking up in /.yml we lookup :: in .yml

This is a useful plugin for people wanting to test drive Jerakia but maintain an existing hiera filesystem layout and naming convention within the source data.

# File 'lib/jerakia/lookup.rb', line 37

def scope
  @scope_object.value
end

#stop ⇒ Object

lookup function: stop Enabling stop sets @proceed to false, which will cause Jerakia not to load any more lookups in the policy if this lookup is deemed as valid. If the lookup is invalidated than Jerakia will progress to the next lookup. This is useful in conjuction with the confine plugin where we want to segregate some lookups but not worry about excluding from later lookups
