Extending a defined type

[Angel L. Mateo]

Hi,

I would like to add to existing nagios_* types the possibility to
define custom variables
(https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/3/en/customobjectvars.html).

I have found a few tickets like
https://tickets.puppetlabs.com/browse/PUP-1067 or
https://tickets.puppetlabs.com/browse/PUP-1075 but it seems there are
blocked.

So I'm thinking the possibility to create my own types extending them.
Is there any documentation about extending types. All documentation I
have found is about creating a completely new type, but I haven't found
any about inheriting an existing one.

You can fairly easily extend a resource or type by wrapping it in a new one of your own making.  The concept is similar to inheritance in object oriented languages, but the mechanism is a little less sleek.

I'm picking a resource with a small list of attributes to keep the example simple, but you can do this with anything.

define my_notify (
  $name     => $title,
  $message  => undef,
  $withpath => undef,
  $my_notify_special,
){
  # do custom things here
  notify { $title:
    name     => $name,
    message  => $message,
    withpath => $withpath,
  }
  # do more custom things here, maybe with $my_notify_special
}

I'm not sure I can do what we want with a define. I want to add a
property to the nagios_* types so I can define custom variables in
nagios objects. Since the actual nagios object is handle with puppet
types, I think the define is not appropriate for this.
