Puppet users - Apr 2010 - Evaluate the value of a variable's value

Hi,

Is it possible for puppet to do the equivalent to this in bash:
andrew@comet:~$ a=1
andrew@comet:~$ x="a"
andrew@comet:~$ eval echo \$$x
1

Or this perl:
#!/usr/bin/perl
$a=1;
$x="a";
print $$x;
(Output would be 1)

Or would I need to write a function to do this?

Thanks,
Andrew

It''s possible with inline_template():

dan.carley@jim ~ $ puppet
$a = 1
$x = "a"
notice("Bad:", inline_template("<%= x %>"))
notice("Good:", inline_template("<%= $x %>"))
^D
notice: Scope(Class[main]): Bad: a
notice: Scope(Class[main]): Good: 1

That is exactly what I was looking for. Works great, thanks!
