Re: [Puppet Users] access exported resources in template
I don't quite know the answer, and I agree, a running shell would be useful. I'd be looking in Parser::Scope and the TemplateWrapper class, wherever it is. Those should generally cover it, with maybe Parser::Resource. You should try deeper inspection of the resources. I think 'resource.to_hash' should give you all of the resource's parameters.

Re: [Puppet Users] access exported resources in template
Well, 3 years old or not, this is still in the first page of google results haha. I'm running puppet version 2.7.9 and the result of that template is a blank comment line for every instance of the Firewall::Rule type. If I replace 'resource[:comment]' with 'resource.type' then I can confirm that the iteration is actually working, because I see comment lines like this '# Firewall::Rule'. I tried 'resources["comment"]', 'resources[:comment]', and 'resources.comment' (with this one triggering an error). I wish there was some easy way to get an interactive ruby shell running with the same environment so I could actually test this without running puppet apply every time, if I could I probably would have figured it out on my own already. If you don't know what the answer is, could you maybe point me in the general direction of how you would find out? Perhaps a relevant part of the puppet source code? And thanks for answering.

Re: [Puppet Users] access exported resources in template
Wow, talk about a blast from the past. I don't get a lot of replies to 3 year
old email. :)
What happens when you do this? It looks like it should basically work,
although I'd use 'resources' instead of 'vertices', I think. What version is
this?

Re: [Puppet Users] access exported resources in template
The resource[:property] method doesn't seem to work. I'm pretty new with
puppet and only just learned ruby, so I was hoping someone could perhaps
just point me in the right direction. Here's what I've got so far:
<% scope.compiler.catalog.vertices.each do |resource| -%>
<% if resource.type == "Firewall::Rule" -%>
# <%= resource[:comment] %>
<% end -%>
<% end -%>
where Firewall::Rule is defined something like:
define firewall::rule ($comment=$title){}
Any ideas?

[Puppet Users] access exported resources in template
Hi,
I'm trying to develop a class that autogenerates a config file based
on an .erb template.
It shall populate the config file with data exported from various hosts.
Some pseudocode to clarify my issue:
node n1 {
@@mytype {
"name":
property => "foo"
}
}
template.erb:
<% mytype.each do |bar| %>
<%= bar.name %>
<%= bar.property %>
<% end %>
My question is: How can I access and iterate through the exported
resources in the template? mytype.each will not work...
best regards
Bernhard
