Puppet users - Feb 2011 - returning a hash (json object) from custom function?

We have a command line utility that queries a database to get certain
facts about our hosts -- I wanted to write a custom function to obtain
all of those facts at once.  The tool outputs JSON and I wanted to
take that output and return a hash back into puppet where I could
access the facts like...

$a = host_info()

if $a[''in_maintenance''] == ''yes'' {
} ...

etc, etc.

Right now I''m getting:

can''t convert Array into String at ... Which I assume means that
puppet is expecting a string back from the custom function.

Maybe I just need to make a fact out of these instead and prefix them
with foo_in_maintenance, etc., etc., etc., but I''d really rather use
structured data.

Ok, I was mistaken.  Returning a hash works.  It would be helpful if
the ruby exceptions bubbled up to puppet reported the correct line
number from the ruby source -- if that is possible.

Could you file a bugreport[1], if there isn''t yet one? Thanks!
Then the chances are high that it will get fixed.

I''d love to, but so far no matter how many times I reset my password,
it thinks my login is invalid.
