Arrays from templates

[pablo]

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
