Puppet's Search function

[Robb Wagoner]

Hello all,
I have read through the sparse documentation on the Search (intentionally capitalized to differentiate from the verb) function as well as searched the group list (and mail archives) with little success to finding an answer. It is my understanding that I want to use the Search function to achieve my goal.

I would like to know:
a) is my understanding about the purpose of this function incorrect?
b) the recommended way to accomplish making variables defined in classes available to other classes, dynamically (see below as an example).

Using a contrived example, I have a series of classes with site-specific settings & variables:

site::office
site::datacenter
etc.

In each of these classes I have some site-specific variables defined that I want to be able to reference in other classes.

manifests/site.pp:
$site_name = "office"

site/manifests/office.pp:
class site::office inherits site::common {
  $dns1 = "1.2.3.4"
  $dns2 = "2.3.4.5"
  $search = "$site_name.local"
}

bind/manifests/dns.pp:
class dns::client inherits dns::common {
  search "site::$site_name"

  file { "/etc/resolv.conf" :
    content => "search $search\n nameserver $dns1\nnameserver $dns2\n"
  }

}

I get error that the variables, $search, $dns1, et cetera are unknown.

Thank you and regards,
Robb

Your understanding is incorrect. I came up against this lack of
documentation the other day so went looking to see what the code did; it
turns out that it adds nested classes and defines from other classes
into the local class but not variables. You'll find the relevant code
in parser.rb and scope.rb.

would be nice if you could add this documentation to the wiki,
because... eh it's a wiki!

thanks and cheers

Bruce,
Thank you for the explanation. I will review the parser.rb and
scope.rb to familiarize myself with the code.

The functions reference page is autogenerated. What is the source, if I
am to update it?

Log a ticket in Redmine with your updates.

Thanks

the code.

However for more extended example it might be nice to create wiki page.
But if it's just a few lines, I think James is fine with code patches.

OK, having already registered on the wiki, I just tried to register on
redmine and it's returning an error.

I'll submit a patch but it sounds like it might be a good idea to change
the template for the function references page to include a link to
/track/wiki/Function_Usage_Examples#functionname . I'd happily populate
that page and then bug people to correct my mistakes and fill in the
gaps. If nobody can suggest a better name, I'll take some time to day
to create that page in the hope that the links will appear later.
