From c9f906f80325a12a6509633d87472bd3cbaf0364 Mon Sep 17 00:00:00 2001 From: Yanis Guenane Date: Mon, 15 Sep 2014 14:16:52 -0400 Subject: (MODULES-1329) Allow member function to look for array Currently, the member function allows one to only find if a variable is part of an array. Sometimes it is useful to find if an array is part of a bigger array for validation purpose. --- lib/puppet/parser/functions/member.rb | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) (limited to 'lib/puppet/parser/functions') diff --git a/lib/puppet/parser/functions/member.rb b/lib/puppet/parser/functions/member.rb index 11a1d24..bb19a86 100644 --- a/lib/puppet/parser/functions/member.rb +++ b/lib/puppet/parser/functions/member.rb @@ -8,6 +8,7 @@ module Puppet::Parser::Functions newfunction(:member, :type => :rvalue, :doc => <<-EOS This function determines if a variable is a member of an array. +The variable can either be a string or an array. *Examples:* @@ -15,9 +16,17 @@ This function determines if a variable is a member of an array.
