[Puppet Users] DRY duplicated manifest code

[Matt Zagrabelny]

Greetings Puppet Users,

I have a chuck of code I'd like to centralize - you know DRY.

I've looked into a custom function, but I'm uncertain how to get at
the the puppet resources inside of ruby.

Here is the verbatim copy of the chuck in a puppet manifest:

if defined(Service['apache2']) {
    $services_to_notify = [
        Service['apache2'],
    ]
}
else {
    $services_to_notify = []
}

and here is some hand-wavy pseudocode:

function return_service_array_if_defined($service) {
    if defined(Service[$service]) {
        return [
            Service[$service],
        ]
    }
    else {
        return []
    }
}

Any suggestions or ideas for implementation?

Thanks!
