Request feature to normalize case in Hiera interpolation tokens within hiera.yaml

Issue Type:	New Feature
Assignee:	Unassigned
Components:	Hiera & Lookup
Created:	2022/06/02 3:00 PM
Priority:	Normal
Reporter:	Taika Augustaitis

Desired Behavior: Requesting a feature to normalize case similar to the downcase function within Hiera interpolation tokens in hiera.yaml. This is needed to minimize the need to duplicate yaml files because fact values may have different case.

Actual Behavior: Currently the workarounds include creating multiple yaml files with the same contents and creating custom facts.

taika.augustaitis can you help us understand where the facts are defined, whether the fact can downcase the value so we don't have to add complexity to the hiera lookup

Re: Request feature to normalize case in Hiera interpolation tokens within hiera.yaml

Seems far better to normalize the facts values.

An open ended solution would be to make the interpolation syntax of values in hiera.yaml be able to describe arbitrary function calls (to puppet functions) thereby making it possible to transform values used in paths. This would cater to other requests as well were users need to process values in other ways. This is somewhat difficult though due to the syntax of hiera interpolations so it can be hard to find suitable operators without causing breaking changes. An alternative discussed in the past was to allow one or more function calls to be listed in the hiera.yaml under a new top level key - each entry would name a (new) variable and the returned value of the function call would be the value. Those variables would be local to hiera.yaml. For example:
