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

The following worked for me.

puppet apply -e ' $y = "Hello" $z = "world" $x = "$y $z" notify { "$x": } '
notice: Hello world
notice: /Stage[main]//Notify[Hello world]/message: defined 'message' as 'Hello world'
notice: Finished catalog run in 0.04 seconds

The following works as well:

$abc = "def"

file { "/tmp/$abc":
