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.
