After a lot of trial and error here's what I came up with. It may not be
elegant, but it works. It will pull in all hosts that match on the
${environment} in this case "test", so it pulled in test-search001,
test-search002, test-search003 & test-search004.
#Custom function searchparse
module Puppet::Parser::Functions
newfunction(:searchparse, :type => :rvalue) do |args|
oldarray = args[0]
newarray = Array.new
pos = 0
oldarray.each do |value|
newarray.push(value['name'])
pos = pos + 1
end
return newarray
end
end

$f = {

}
$hostlist = foreman($f)
$hostlist2 = $hostlist['results']
$hostlist3 = searchparse($hostlist2)
