How do you concatenate strings in a Puppet .pp file?

Question

Here is my naive approach:

# puppet/init.pp
$x = \'hello \' + 
     \'goodbye\'

This does not work. How does one concatenate strings i

Answer 1

Another option not mentioned in other answers is using Puppet's sprintf() function, which functions identically to the Ruby function behind it. An example:

$x = sprintf('hello user %s', 'CoolUser')

Verified to work perfectly with puppet. As mentioned by chutz, this approach can also help you concatenate the output of functions.
