Module:GetRecipes

Documentation

This module is called by Template:GetRecipes, and is the entry point for modules in the system that displays crafting recipes. It takes the item passed to the template, and uses Module:CraftingRecipes to get every recipe related to the item. The resulting list of recipes is then passed to Module:CraftingParser, and the results from CraftingParser are returned to the template.

If the template is passed, this module creates a table using details from the following Modules:

• Module:Utils
• Module:CraftingParser
• Module:CraftingRecipes
• Module:RecipeTable
