wiki/Crafting-Guide-Data-Format-V2.md

Version 2 of the Crafting Guide file format is a very simple command-based language which is very similar to YAML. There are commands for entering all various kinds of data needed to describe a mod, its items, and the recipes for those items. Most commands are optional, and can be entered in any order. Anywhere this isn't true will be called out below.

Example

schema: 2
name: Applied Energistics 2
version: rv1-stable-1

    recipe:
        input: Iron Ingot
        pattern: ... .0. ...
        quantity: 3

    recipe:
        input: Tin Ingot
        pattern: ... .0. ...

        tools: Nether Quartz Cutting Knife

Commands

• schema: <version> (required)

  The data schema used by the file. The current version is: 2.

• name: <mod name> (required)

  The name of the mod described in the file. This should be the full name of the mod as referred to in its own documentation; only use abbreviations if they are as commonly used as the full name itself (e.g., "IC2").

• version: <mod version> (required)

  The version of the mod being described by the file. This should use whatever version scheme is used by the mod itself, and should match whatever is shown in the in-game "Mods" screen.

• item: <item name>

  Starts and item declaration. The item name should be the item's actual in-game name. Spelling, punctuation (if any), and spaces are relevant. Extended UTF-8 characters are permitted.

  This command should be used once for each item in the mod. You should avoid using it to declare any items from vanilla Minecraft, or from other mods as these will already be added by other files.

  After an item declaration, the following commands may be used to describe it: gatherable, recipe.

• gatherable: [yes|no]

  Indicates whether an item may be gathered in-game without crafting (e.g., Iron Ore can be gathered, but Iron Ingots cannot). If an item is gatherable, then it will never be crafted, even if it has recipes listed (e.g., Diamonds will never be crafted, even though they could be made from Diamond Blocks).

• recipe:

  Starts a recipe declaration. This should be repeated once for each unique way of making the given item. Due to limitations with the crafting algorithm, the following rules should be followed when entering recipes:

  1. Do not enter multiple recipes for alternate ingredients. For example, sticks can be made from
     any combination of any kind of planks (e.g., Oak Wood Planks, Spruce Planks). When entering a recipe for such an item, simply choose a variant of the ingredients and enter a single recipe using that variant (e.g., only use Oak Wood Planks).
  2. Break cycles using gatherable.
