require 'hiera_puppet'
module Puppet::Parser::Functions
newfunction(:hiera, :type => :rvalue, :arity => -2, :doc => "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. This option can only be used with the 3x future parser or
from 4.0.0.
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>
") do |*args|
key, default, override = HieraPuppet.parse_args(args)
HieraPuppet.lookup(key, default, self, override, :priority)
end
