module Puppet::Parser::Functions
  newfunction(:reject, :type => :rvalue, :doc => <<-DOC) do |args|
    @summary
      This function searches through an array and rejects all elements that match
      the provided regular expression.

    @return
      an array containing all the elements which doesn'' match the provided regular expression

    @example **Usage**

      reject(['aaa','bbb','ccc','aaaddd'], 'aaa')

      Would return: ['bbb','ccc']

    > *Note:*
    Since Puppet 4.0.0 the same is in general done with the filter function. Here is the equivalence of the reject() function:
    ['aaa','bbb','ccc','aaaddd'].filter |$x| { $x !~ /aaa/ }
DOC

    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
end
