Puppet users - Feb 2013 - Hiera question -- accessing a hash from an erb template

Hi All,

Simple question (hopefully). Say I have this:

common.yaml:

foo:
   bar: 10GB

... and in the manifest:

$config = hiera(''foo'')

file { ''/etc/foo.conf'':
   content => template(''module/foo.erb'')
}

... and in foo.erb:

file_size: <%= @config[''bar''] %>

For some reason, the output in /etc/foo.conf will be ''10GB'' on
its own
line, instead of ''file_size: 10GB''. Almost as if there is a
funny character
in there?

Any ideas?

Thanks.
Gonzalo

Maybe there''s a funny character in there.  Seriously.

Especially if you have a mixture of Windows and Unix, you might 
accidentally end up with carriage return characters (ASCII 0x0D) in some of 
your text files on the Unix side.  Different Unix editors, viewers, and 
utilities may handle that situation differently.

Examine both your template and your data file for unexpected characters.  
Many Unix text editors have modes in which they will display such 
characters to you (and thus allow you to edit them out).  To just see 
whether there are any, you could try listing the files via ''cat 
--show-nonprinting''

Thanks John for replying. Odd stuff but just before this line, I had
another <%= ... %> block and replacing %> with -%> on the previous
block
seems to have done the trick.
