Module:Item recipe

Module documentation
View or edit this documentation • (about module documentation)

Uses JSON data

This module uses JSON data pages:

• Module:Item recipe/recipes by recipe IDs.json
• Module:Item recipe/recipe IDs by product IDs.json
• Module:Item recipe/recipe IDs by method and availability.json
• Module:Item recipe/order of materials.json
• Module:Item recipe/product overrides.json

Implements {{item recipe}}.

JSON files

JSON files that are updated automatically, syncing with the upstream:

• Module:Item recipe/recipes by recipe IDs.json - contains 1 to 1 mapping of recipe IDs to recipes.
• Module:Item recipe/recipe IDs by product IDs.json - contains mapping of recipe products to recipe IDs that produce these...products. Can be 1 to 1, or 1 to many.
• Module:Item recipe/recipe IDs by method and availability.json - contains a mapping of recipe production methods (e.g. Autolathe) to → availability (condition under which a recipe is available for this production method) to → recipe IDs.

Warning

Do not make changes to the above JSON files - any changes made will be erased on next update.

JSON files that are filled manually:

• Module:Item recipe/order of materials.json - a 1 to 1 mapping of recipe materials to order at which they appear in recipes. Less number = higher order. Materials that do not have an order defined here, will appear after those that do.
• Module:Item recipe/product overrides.json - a 1 to 1 mapping of recipe products to item IDs. Not all products are the same as item IDs they "represent", so sometimes a connection needs to be established explicitly.

-- Searchs for a recipe product based on item ID that a recipe should produce.
-- Not all recipes produce products that you might think they do -

--
-- For instance, a recipe for the small power cell produces `PowerCellSmallPrinted` item,
-- whereas the actual power cell item has ID `PowerCellSmall`.
--
-- So, to find the recipe for the small power cell, we first would need to define a mapping from
