Puppet users - Nov 2012 - how to query yaml file with hiera function.

Hi guys,

i have a hiera.yaml config file like this:

---
:hierarchy:
    - %{env}/%{tmp_module_name}
    - %{env}/%{tmp_module_name}.common
:backends:
    - yaml
:yaml:
    :datadir: ''/etc/puppet/hieradata''


I also have a test/some_module.yaml file like this:

---
db:
    root            : pass
    port            : ''3306''


I am also using the hiera function from a template like this

class.pp
$::class::var=''db''

template.erb
 <%= scope.function_hiera([var]) %>

and that returns  as expected the ''db'' hash...

however , I would like to query the yaml file directly from the hiera 
function with something like:

scope.function_hiera([var:root]), so to have access directly to the 
root:pass pair. but that doesnt seem to work.

I''ve tried several possibilities, eg: ([var:''root'']),
([$var::''root'']),
([$::class::var:root]), ([var:[''root'']]) without success,


Now i know that something like <%=
scope.function_hiera([var])[''root'']
would work!

The problem with this approach is that the next level in the hierarchy 
would never be reached since the ''db'' key will always be
located in the
first level... but what if I would like to use something like this:


First search level:


---
db:
    root            : pass
    port            : ''3999''




Second search level


---
db:
    root            : pass
    port            : ''3999''
    path           : ''foo''


then the path:foo pair would never be located...

Btw, are there any plans to fix this soon:

thanks in advance,

Try this: <%= scope.function_hiera([var[''root'']]) %>

here is my func:

<%= scope.function_hiera([cluster[''port'']]) %>

yaml file:

---
cluster:
    root            : pass
    port            : ''9938''



thanks in advance..
