[Puppet Users] variable name containing variable name
Hello, i''m new to puppet (and ruby).
I have a problem when using a variable name containing a variable name
and containing a reserved variable name :
I have a class :
class kernel-Linux-binary {
$test = $operatingsystem ? {
Fedora => "/usr/bin/test",
default => undef
}
}
and i want to call "test" and replace Linux by $kernel to have a
generic
call.
If i write $kernel-$kernel-binary::test, puppet try to call
Linux-Linux-binary::test
What is the good solution ?

Hash: SHA1
perhaps calling ${kernel-$kernel-binary::test} would solve your problem

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 so you try to evaluate a valid binary for "test" what about setting "path => " within the exec you have in /home/puppet/manifests/services/mail.pp aroune line 22 ? if you set all paths where the test-binary may be on all you systems and just use "test" (not "/usr/bin/test") within the onlyif parameter it should work. doesn''t it?

I think there is examples where it should be good to have generic code. For example, i can do : include "operatingsystem-$operatingsystem" and it''s very useful. -- | Christophe GUILLOUX - Service AMI - Bureau A017 | | Centre de Recherche INRIA Rennes - Bretagne Atlantique | | Campus de Beaulieu | | 35042 Rennes cedex, France | | PHONE : +33 (0) 29984 74 10 | FAX : +33 (0) 29984 71 71 | | WWW : http://www.inria.fr | JABBER : christophe.guilloux@irisa.fr |

[Puppet Users] Re: variable name containing variable name
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1> include "operatingsystem-$operatingsystem"that one should work out of the box - if this generates an error it should look like "operatingsystem-${operatingsystem}" Yet, I am not quite sure when puppet needs those parentheses and when it doesn''t - but I never stumbled upon a case where puppet threw an error complaining about them beeing used. I guess it has something to do with strings - if you use a variable within a string those parentheses are necessary. In my classes I use lots of such calls - using variables in names for files, packages, services and so on - just to be sure nothing is declared twice and to reuse those declarations.
