require 'hiera/puppet_function' # Performs a standard priority lookup and returns the most specific value for a given key. # The returned value can be data of any type (strings, arrays, or hashes). # # The function can be called in one of three ways: # 1. Using 1 to 3 arguments where the arguments are: # 'key' [String] Required # The key to lookup. # 'default` [Any] Optional # A value to return when there's no match for `key`. Optional # `override` [Any] Optional # An argument in the third position, providing a data source # to consult for matching values, even if it would not ordinarily be # part of the matched hierarchy. If Hiera doesn't find a matching key # in the named override data source, it will continue to search through the # rest of the hierarchy. # # 2. Using a 'key' and an optional 'override' parameter like in #1 but with a block to # provide the default value. The block is called with one parameter (the key) and # should return the value. # # 3. Like #1 but with all arguments passed in an array. # # More thorough examples of `hiera` are available at: # <http://docs.puppetlabs.com/hiera/1/puppet.html#hiera-lookup-functions> Puppet::Functions.create_function(:hiera, Hiera::PuppetFunction) do init_dispatch end
