Recipe format

The recipe format, as currently used in mineflayer.

{ // dictionary of ID -> recipes for that ID
	"<result ID>": [ // list of recipes
		{ // one recipe to get an item with ID <result ID>
			"type": "<result ID>"
			"metadata": "<result damage>",
			"count": "<result amount>",
			"inShape": [ // the crafting grid, list of rows
				[ // one row of the crafting grid
					"<A1>",
					"<A2>",
					"<A3>"
				], [
					"<B1>",
					"<B2>",
					"<B3>"
				], [
					"<C1>",
					"<C2>",
					"<C3>"
				]
			],
			"outShape": ["..."] // optional, same as inShape,
			                    // but the items that remain
			                    // in the grid after crafting
		},
		{ // another recipe for the same ID, but maybe different meta
			"type": "<result ID>"
			"metadata": "<result damage>",
			"count": "<result amount>",
			"ingredients": [ // list of ingredients
				{
					"id": "<ingredient ID>",
					"metadata": "<ingredient damage>" // optional
				}
			],
		},
		{ // another recipe for the same ID, may be for different meta
		// ...
		}
	],
}

The crafting grid looks like this:

A1 A2 A3
B1 B2 B3
C1 C2 C3

When the required grid is smaller, empty rows/cells may be omitted:

A1 A2

would be "inShape": [["A1", "A2"]],

A1
B1

would be "inShape": [["A1"], ["B1"]],

The numbers (A1 to C3) in inShape are the required item's ID, or null if empty.

result ID is duplicated for convenience.

Json schema

The json schema automatically checks whether the recipes.json respects that format.
