This package is now deprecated, please install this VS Code extension as a replacement. The alternative VS Code extension can provide far better support for data pack JSONs. (I created both extensions, btw.)

If you're a programmer who's interested in the schemas, I'd suggest you take a look at this.

Installation

npm i datapack-json

Custom Properties

There are two custom properties for string schema: parser and params, which should be used to validate the content of the string.

List of Parsers

Command Parser

A parser used to validate commands.

Parameters

• leadingSlash: (boolean | null) Whether the command should start with slash (/). The string won't be validated if the value doesn't start with slash and the parameter is set to true.

Entity Parser

A parser used to validate entities.

Parameters

• amount: (single | multiple) The acceptable amount of entities.
• type: (entities | players) The type of the entities.
• isScoreHolder: (boolean) Optional, defaults to false. Whether this entity is a score holder.

Identity Parser

A parser used to validate namespaced IDs.

Parameters

• registry: (string) Optional. The registry of this namespaced ID. Can be one of:
  • $advancements: All available advancements.
  • $functions: All available functions.
  • $loot_tables: All available loot tables.
  • $predicates: All available predicates.
  • $recipes: All available recipes.
  • $storages: All available recipes.
  • $tags/blocks: All available block tags.
  • $tags/entity_types: All available entity type tags.
  • $tags/fluids: All available fluid tags.
  • $tags/functions: All available function tags.
  • $tags/items: All available item tags.
  • $objectives: All available scoreboard objectives.
  • $teams: All available teams.
  • Other strings should be treated as the name of a built-in registry which can be found in the registry.json file generated by the data generator.
• values: (object) Optional. All possible IDs that can be put in this string.
• allowTag: (boolean) Optional, defaults to false. If set to true, an ID starting with # under the corresponding registry should be accepted.
• allowUnknownValue: (boolean) Optional, defaults to false. If set to true, IDs that don't exist in neither registry nor values won't be reported as errors.

NbtPath Parser

A parser used to validate NBT paths.

Nbt Parser

A parser used to validate NBT tags.

Parameters

• type: (NbtNodeTypeName | NbtNodeTypeName[]) The type of this NBT tag.
• category: (minecraft:block | minecraft:entity | minecraft:item) The type of this NBT.
• id: (string) Optional. An ID in the specific category.
• isPredicate: (boolean) Optional, defaults to false. Whether this NBT is in a predicate or not.

Objective Parser

A parser used to validate scoreboard objectives.

TranslateKey Parser

A parser used to validate translation keys in resource packs.

Vector Parser

A parser used to validate number vectors.

Parameters

• dimension: (number) The dimension of the vector.
• allowLocal: (boolean) Optional, defaults to true. Whether local coordinates are acceptable.
• allowRelative: (boolean) Optional, defaults to true. Whether relative coordinates are acceptable.

File Struture

• src: Stores all JSON Schemas.
  • shared: Stores all common JSON Schemas.
  • tags: Stores JSON Schemas for tags.
  • advancement.json: JSON Schema for advancements.
  • loot_table.json: JSON Schema for loot tables.
  • pack.mcmeta.json: JSON Schema for pack.mcmeta.
  • predicate.json: JSON Schema for predicates.
  • recipe.json: JSON Schema for recipes.
• utils: Stores useful tools.
  • convert.js: Convert registries.json generated by Minecraft data generator to shared files.
