I finally did it my self.
For sure I hate Ruby.
This custom function will add values from arbitrary keys (must be arrays)
at the beginning of "hierarchy"
For my example, I have just included hiera_hook("roles") in site.pp to
achieve to behavior I described previously.
module Puppet::Parser::Functions
newfunction(:hiera_hook) do |*args|
require 'puppet/indirector/data_binding/hiera'
require 'hiera'
require 'hiera/scope'
require 'puppet'
key, default, override = HieraPuppet.parse_args(args)
value=HieraPuppet.lookup(key, default, self, override,
:priority)
hierarchy=Puppet::DataBinding::Hiera.hiera().config[:hierarchy]
value.each do |val|
if not hierarchy.include?(val)
hierarchy.insert(0,val)
end
end
end
end
