Puppet DSL String concatenation

Question

is there a string concatenation operator in the Puppet DSL? It appears that there is currently no such thing. But how do i achieve the objective of string concatenation in puppet? How do I create a string composed of multiple string values?

Answer 1

Method 1: One way is Keyword variable interpolation:

$value = "${one}${two}"

Source: http://docs.puppetlabs.com/puppet/4.3/reference/lang_variables.html#interpolation

Note that although it might work without the curly braces, you should always use them.

Method 2: Another option is using Puppets sprintf() function, which functions identically to the ruby function behind it. 

An example:

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

It is verified to work perfectly with puppet. This approach can also help you concatenate the output of functions.
