Registry Dump

Dump all IDs of known registry entries into JSON files.

/dump registry

A specific registry can also be specified, by default all registries are exported.

/dump registry minecraft:item

The JSON files are created under dump within your minecraft directory and take the following shape:

dump/[registry key]/[namespace].json

For example

dump/banner_pattern/minecraft.json
dump/item/brazier.json
dump/worldgen/biome/minecraft.json
dump/worldgen/biome/environmental.json

The content of these files is a simple JSON array containing all keys withing that registry/namespace combo.
