module Puppet::Parser::Functions
  newfunction(:reject, :type => :rvalue, :doc => <<-EOS) do |args|

    if (args.size != 2)
      raise Puppet::ParseError,
        "reject(): Wrong number of arguments given #{args.size} for 2"
    end

    ary = args[0]
    pattern = Regexp.new(args[1])

    ary.reject { |e| e =~ pattern }
  end
