Puppet users - Mar 2012 - Arrays from templates

Hi,

I am having an issue trying to use the inline_template function to 
return an array. This is what I do:

$array = inline_template ("<%=
a=[''a1'',''b2'',''c3'']; a
%>")
notify {"array: ${array}":}

And that works, showing the typical comma-less string:
notice: /Stage[main]//Notify[array: a1b2c3]/message: defined
''message''
as ''array: a1b2c3''

But when I try to access just one element of the array, it breaks:
notify {"array: ${array[1]}":}

And I get:
err: Could not retrieve catalog from remote server: Error 400 on SERVER: 
array is not an hash or array when accessing it with 1 at 
/home/pablof/puppet-tree/manifests/groups.pp:27 on node

I have been trying, and it seems like the inline_template recognizes 
external array declared this way (as arrays) but Puppet doesn''t... am I
missing something? Do I have to convert the output to some type Puppet 
understands?

Thanks!!
Pablo

inline_template can only return strings, not arrays or hashes.

You''ll need to write a parser function
