Hiera YAML Array

This is a fork of hiera YAML backend with support for array variable interpolations.

Array interpolations

If bar is a variable defined as an array in puppet and you have the following variable interpolation in the YAML file:

foo: '%{bar}'

The result sill be the same as:

foo:
  - bar[0]
  - bar[1]
  - ...

On original hiera backend the array variable is just casted to a string.

To trigger this array expansion behavior the string where the interpolation is in should contain just one variable and nothing more.

gem install hiera-yaml-array

Same as the Yaml backend, but use the key yaml_array instead of yaml.
