Issue #5236 has been updated by Ken Barber.
Status changed from Accepted to Closed
Actually this does work:
hostclass :foo, :arguments => {"myparam" => nil} do
notice [scope.lookupvar("myparam")]
end
node "default" do
create_resource :class, :foo, :myparam => "foo"
end
Which is functionally the same as:
class foo ($myparam) {
notice($myparam)
}
node "default" {
class { "foo": myparam => "foo" }
}
I've updated the Wiki to reflect this:
<http://projects.puppetlabs.com/projects/puppet/wiki/Ruby_Dsl>
And added another sample to my rubydsl-examples site:
<https://github.com/bobsh/puppet-rubydsl-examples/blob/master/classes/classes2.rb>
I'm going to close this ticket, as it seems like it was primarily a
documentation issue.

Bug #5236: Ruby DSL cannot declare parameterized classes
https://projects.puppetlabs.com/issues/5236
Author: Dan Bode
Status: Closed
Priority: High
Assignee:
Category: API
Target version:
Affected Puppet version:
Keywords: internal dsl hostclass
parameterized_classes
Branch:
it should be possible to declare parameterized classes using the ruby dsl:
/tmp/notify.rb
<pre>
hostclass 'foo', 'bar' do
notify 'foop', :message => 'foobar'
end
node 'default' do
hostclass 'foo', :bar => 'test'
end
</pre>
trying to apply the above manifest, results in the error below.
