Puppet users - Apr 2009 - Treating floats as strings

I think I''m running into situations where my variables are being used
as
floats instead of strings.

For example, if my puppet_node_classifier prints this:
---
parameters:
  version: 0.10

and my command is this:

command => "/bin/rpm -hiv
http://server/package-$version.x86_64.rpm"

I think it will attempt to install version 0.1 of my package instead of
version 0.10. Is there a way to force the variable to be treated as a string
instead of a float in this type of situation?

Did you try double-quoting the number as in:

Excellent idea, thanks!

I was using perl''s YAML module to just dump a hash:

print Dump( {
    parameters=> \%parameters
} );

Now I''m just producing the output myself:

print "---\nparameters:\n";
foreach my $key (sort keys %parameters) {
        if (defined $parameters{$key}) {
                print "  $key: \"$parameters{$key}\"\n";
        }
}

I''m not quite sure how to tell YAML module to treat everything as a
string
(stringify didn''t seem to cut the mustard), but this workaround does
the
trick.
