JSON files

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

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.

-- Contains utilities for working with in-game item recipes.

-- todo: material sorting. based on alphabetical sorting? maybe at .json generation step, convert materials to an array?

local p = {} --p stands for package
local getArgs = require('Module:Arguments').getArgs
local itemModule = require('Module:Item')
local yesNo = require('Module:Yesno')

-- An array of recipe groups.
-- Recipes are grouped by `method`.
-- Note that the order matters for perfomance - the recipe lookup happens from top to bottom.
local recipe_groups = {
	{ method = "autolathe", 	recipes = mw.loadJsonData("Module:Item recipe/recipes by lathe/autolathe.json") },
	{ method = "protolathe", 	recipes = mw.loadJsonData("Module:Item recipe/recipes by lathe/protolathe.json") },
}

-- A table mapping overriding some recipes' products.
-- Keys are the recipe products, values are the new products for these recipes.
-- It's advised to use item IDs for values, as they offer much more perfomance.
-- 
-- Used for recipes which use separate items for produced items,
-- which are the same or almost the same as regular variants.
-- This lets the system know the proper items to display. 
local recipes_products_overrides = mw.loadJsonData("Module:Item recipe/product overrides.json")

-- A table containing item recipes, identified by recipe IDs.
-- local recipes_by_recipe_id =

-- A table containing item recipe categories, identified by recipe category IDs.
-- local recipy_categories_by_recipe_category_id = mw.loadJsonData("Module:Item recipe/recipy categories by recipe category id.json")
