Better Datapacks

The mod widens the scope of what a datapack can express. Its execute command gains a raycast subcommand, and a calculate command performs math operations on numbers and stores the results anywhere a datapack can reach. Recipes gain new types: an empty type removes a recipe without writing an error to the log, a potion type creates potion recipes, and NBT-aware shaped, shapeless and smithing recipes are available.

Advancements can use a block-broken trigger, and events can be defined in an events folder in a datapack, following the same pattern as advancements. Negative tags let a datapack remove a single entry from an existing tag without rewriting the whole tag. The author describes the aim as improving on the datapack system while staying close to vanilla behavior.
