Puppet users - Nov 2011 - why puppet template erb convert On to true, Off to false?

Dear all,

I have a parameterized class and I have my ECN in perl as followed:

classes{''myclass''} = { "abc" => On,};

and in my template erb:

SecRuleEngine <%= abc %>

----

When I applied this to my puppet agent, I would then get:

SecRuleEngine true.

How is that On becomes true and Off becomes false?  How can I fix
this?

Thank you very much.

Do you get exactly the same thing if you quote "On" so it''s
actually a
string?

I''m not sure which part of Ruby is doing the magical translation that
you
don''t want, but you definitely shouldn''t get it if you tell
Puppet that
"On" is a string.

I actually put "On" in double quote in my ECN and I did not get the
desired output.

This is quite weird as why On/Off has been converted to true/false in
erb template.

Thank you, Nigel.

Ah, I missed that you''ve got a Perl ENC.

Can you run your ENC by hand and paste the YAML output of the node
definition like this?

e.g. /path/to/enc nodename

and you should get the YAML output.
