Module:Recipe

Documentation for this module may be created at Module:Recipe/doc

-------------------------------------------------------------------------------
-- This module renders the {{Recipe}} template with a nice wikitable.
-- https://hoodedhorse.com/wiki/Against_the_Storm/Template:Recipe.
--
-- The template #invokes Recipe.render(frame), with provided parameters.
-- The template requires at least one of its three parameters, or it will
-- return an error.
--
-- The first parameter `product` specifies that you want a table rendered to 
-- show all recipes that result in the specified product. Make sure it is 
-- spelled correctly, as it appears in the game.
--
-- The second parameter `building` species that you want a table rendered to 
-- show all recipes that are produced in the specified building. Again, make
-- sure it is spelled and puncutated (apostrophes) correctly.
--
-- The third, parameter `ingredient` species that you want a table rendered to
-- show all the recipes that take that ingredient to produce, whether 
-- specifically (like Wood for Planks) or as an option among many. This 
-- parameter is intended to be used by itself, without a product or building
-- named.
-- 
-- The data for the recipes is retrieved from Module:RecipeData, which hides the 
-- variations in the original data from this module that extracts only what's
-- needed to display one or more wikitables on a wiki page. Using the data, this
-- module creates an HTML table.
-- 
-- The table will have exactly one row if both the product and building are 
-- specified. If either is missing, then expect a table with multiple rows.
-- If an ingredient is specified, then the table will likely be very long.
