Puppet users - Jun 2011 - is ruby code allowed in puppet manifest?

Hi,
I''m trying to get the following to work:

class cluster {

  $cluster_name = hostname.slice(0..-2)
.
.
} # class

hoping that if I have a server called appfarmserver1 (obtained from facter,
can I use a fact like this!?), cluster_name will get set to appfarmserver .
. .

puppet --parseonly init.pp says:
err: Could not parse for environment production: Syntax error at
''.'';
expected ''}''

Is there some way to get this to work?  Is there a better, more puppetty way
to do what I want to do, i.e. based on the hostname from fatcer, set the
variable cluster_name for use in a template.

Thanks so much,
Guy Matz

The most "puppety" way to do it is to create a custom fact that will
return this for you, instead of doing it in the manifest.

You could do it in the manifest using an inline ERB template, but it''s
rather hacky.

I definitely recommend going the custom fact route instead.

You have the choice of either a Puppet DSL manifest or a Ruby DSL manifest.
You cannot mix the two within a single file.
