Overview

strsub is in output filter that matches tags in data and replaces them for values in the scope. It mimics the hiera features of being able to embed %var in YAML documents. This output filter may not provide 100% compatibility to hiera but it should cover most scenarios.

Jerakia does not support method or literal interpolations, just straightforward %var and %var

::var will be lookuped up as scope
