This still sounds like a data validation item quite doable with types. https://puppet.com/docs/puppet/5.5/lang_data_hash.html#the-hash-data-type Hash[Enum['proto', 'dev'], String] Hash[Enum['proto', 'dev'], Variant[String, Undef]] > So even if I pass only specific ones I still have to check if there is > a corresponding value for the key, otherwise > > <%= key %> <%= value %> > > will fail. However the odd thing is that I am unable to reproduce what you are seeing with a plain undef in a very simple case. The undef is not stringified for me in puppet 5.4.0. $ cat /tmp/x.pp $x = { 'a' => undef } $c = template('/tmp/t.erb') notice($c) $ cat /tmp/t.erb a is <%= @x[0] %> $ puppet apply /tmp/x.pp Notice: Scope(Class[main]): a is Notice: Compiled catalog for cwl in environment production in 0.03 seconds Notice: Applied catalog in 0.16 seconds Possibly is_a? might help in this case if you need the erb for flexibility. Very simplistically and untested: <%= key %><%= if value.is_a? String then " = #{value}" end %> <%= key %><%= if value.is_a? Array then " = #{value.sort.join(' ')}" end %> Then if you see the undef appear in your output file you will know it exists in the yaml as one of these specific data types. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
