Puppet users - Apr 2012 - querying hiera data without providing host/scope

Hello there,

I need to access the following hiera data in a script:
$ hiera -c /etc/puppet/hiera.yaml tomcats environment=development 
line=intra3
["tc7_test1", "tc7_test8"]
or
$ hiera -c /etc/puppet/hiera.yaml apache_port environment=development 
line=intra3 name=tc7_test1
81

The example on https://github.com/puppetlabs/hiera uses facts of a specific 
hosts.
I don''t want to specify and load each YAML file for each host, because
the
hosts are already defined for a specific line and stage environment:
$ hiera -c /etc/puppet/hiera.yaml hosts environment=development line=intra3
["serverA.domain.tld", "serverB.domain.tld"]

But I can''t get the hiera.lookup to work without providing a scope with
the
facts of a specific host.

I know that I could just call hiera and parse the output, but I thought I 
better ask before doing that.
Maybe I''m even using environment and stage specific hiera data the
wrong
way.

Here is my current hiera config:

$ cat /etc/puppet/hiera.yaml
:hierarchy:
    - %{environment}/%{line}/%{name}
    - %{environment}/%{line}
    - %{environment}
:backends:
    - yaml
:yaml:
    :datadir:
''/etc/puppet/environments/%{environment}/hieradata''
:puppet:
    :datasource: data
$ hiera -c /etc/puppet/hiera.yaml apache_port environment=development 
line=intra3
80
$ hiera -c /etc/puppet/hiera.yaml apache_port environment=development 
line=intra3 name=tc7_test1
81
$ hiera -c /etc/puppet/hiera.yaml apache_port environment=development 
line=intra3 name=tc7_test8
80
$ cat /etc/puppet/environments/development/hieradata/development.yaml
---
# default values for this stage
apache_port: ''80''

$ cat /etc/puppet/environments/development/hieradata/development/intra3.yaml
---
# line specific values
hosts:  - ''serverA.domain.tld''
        - ''serverB.domain.tld''
tomcats:  - ''tc7_test1''
          - ''tc7_test8''

$ cat 
/etc/puppet/environments/development/hieradata/development/intra3/tc7_test1.yaml
---
# tc7_test1 specific values
apache_port: 81


Thanks in advance!

In this case the scope is just a hash so the cli command:

$ hiera -c /etc/puppet/hiera.yaml hosts environment=development line=intra3

translates to:

hiera.lookup("hosts", nil, {"environment" =>
"development", "line" => "intra3"})
