Kdly Data (pronounced "cuddly data") is a little library that allows all .json files in resource or data packs to be replaced with .kdl files instead, following the specification for JSON-in-KDL 3.0.1.
Kdly Data currently does not support using KDL for .mcmeta files - this will require some complex changes to the odd system used for loading metadata. I may look into it in the future.
.kdl files used in place of .json will respect data pack priority, and filtering out the .json version of a resource will filter out the respective .kdl version too.
