The manual is here: http://docs.puppetlabs.com/puppet/3/reference/. I
recommend you at least read the entire "The Puppet Language" section, and
that you at least skim the "Resource Types" and "Functions" subsections of
the "Generated References" section. As far as the code Felix proposed, it
uses a resource parameter override. You can read about that, specifically,
here:
http://docs.puppetlabs.com/puppet/3/reference/lang_resources.html#amending-attributes-with-a-collector.
And yes, resource parameter overrides are somewhat of a hack, though useful
at times. In this case, however, I think they are unnecessary. If you are
going to add a defined type to hang the behavior on anyway, then why not
just make it unconditionally define the content via a template? Then you
can achieve the same thing a bit more naturally via a definition such as
this one:
define mymodule::templated_file(
$owner = 'root',
$mode='0644',
... <no $content parameter> ...
$template) {
file { $title:
owner => $owner,
mode => $mode,
# ...
content => template($template)
}
}
