Delete property value

[amateo]

Hi,

I'm deploying a custom type to configure nagios contacts with augeas.

If I'm understanding well, according to http://augeasproviders.com/documentation/development.html if I want to be to remove a property I should use the :rm_node option in the accesor.

In my type I have the property defined as:

newproperty(:service_notification_options) do
    desc 'Nagios configuration file parameter.'
    validate do |value|
      if !value.match?(/^([wucrfsn](,[wucrfsn])*)?$/) then
        raise ArgumentError, "service_notification_options must be a comma separated list of 'w', 'u', 'c', 'r', 'f', 's', 'n' (#{value} provided)"
      end
    end
  end
end

and in the provider I get:

attr_aug_accessor(:service_notification_options,
                    :label => 'service_notification_options',
                    :type => :string,
                    :rm_node => true,
                   )

but with this code I have tried to remove the service_notification_options of a contact, but I can't. The contact in my file is:

define contact {
name fulanito
contact_name fulanito
can_submit_commands 1
email [email protected]
retain_nonstatus_information 1
service_notification_options w
}

I have tried not using the service_notification_options in the puppet resource and passing an empty value, like:

um_nagios_contact {'fulanito':
  target                       => '/tmp/contacts.cfg',
  contact_name                 => 'fulanito',
  email                        => '[email protected]',
  can_submit_commands          => 1,
  retain_nonstatus_information => 1,
  service_notification_options => '',
}

or

um_nagios_contact {'fulanito':
  target                       => '/tmp/contacts.cfg',
  contact_name                 => 'fulanito',
  email                        => '[email protected]',
  can_submit_commands          => 1,
  retain_nonstatus_information => 1,
  service_notification_options => undef,
}

How is the correct way to handle property removal? Or do I have to code myself the writer for the property?

Two options have been considered to fix this:

• keep the value as a string and add an rm_value option: Add rm_value option #19
• use an array value and add a split_by option: Add array split_by option #20

[amateo]

I think they are not exclusive. #20 is only valid when options could be provided as an array (you could use some of them separated by ,) which is not always possible. There are properties that are atomic.
