Module:WorkshopsData

--- --- Module for compiling workshops (or production buildings as they are called --- in-game) information from wiki data sources. Restructures the flat data --- tables that are produced from CsvUtils to make them more conducive to Lua --- methods that need to display the information.

--- The standard way of using this module is a call like the following: --- --- iconFilename = WorkshopsData.getWorkshopIcon(workshopName) --- --- This will return a string corresponding to the filename of the icon of the --- workshop, including the .png extension. It is preferable to call getter --- methods with the name of the workshop rather than retrieving the entire --- record for the workshop, so that your code stays protected from variations --- in this module. The getter methods are all called with the plain-language --- name of the workshop, as spelled in the game. --- --- * longDescription = WorkshopsData.getWorkshopDescription(workshopName) --- * constructionCategory = WorkshopsData.getWorkshopCategory(workshopName) --- * sizeX, sizeY = WorkshopsData.getWorkshopSize(workshopName) --- * requiredGoodID, stackSize = WorkshopsData.getWorkshopRequiredGood(workshopName, requirementIndex) --- * timeSeconds = WorkshopsData.getWorkshopConstructionTime(workshopName) --- * cityScore = WorkshopsData.getWorkshopCityScore(workshopName) --- * isMovable = WorkshopsData.isWorkshopMovable(workshopName) --- * isInitiallyEssential = WorkshopsData.isWorkshopInitiallyEssential(workshopName) --- * storageCap = WorkshopsData.getWorkshopStorage(workshopName) --- * workplaces = WorkshopsData.getWorkshopNumberOfWorkplaces(workshopName) --- * recipe = WorkshopsData.getWorkshopRecipe(workshopName, recipeIndex) --- * iconFilename = WorkshopsData.getWorkshopIcon(workshopName) --- --- And the following getter methods are all called with the workshop's ID. --- You will have an ID instead of a display name when dealing with other game --- data like, recipes, goods, etc. --- --- * name = WorkshopsData.getWorkshopNameByID(workshopID) --- * iconFilename = WorkshopsData.getWorkshopIconByID(workshopID) --- --- The list of workshops that can produce a particular recipe ID can be --- retrieved with the following method --- --- workshopNamesTable = WorkshopsData.getWorkshopNamesWithRecipeID(recipeID) --- --- There are methods to retrieve the lists of required goods, workplaces, and --- recipes, but it is advised to instead use the getter methods --- getWorkshopRequiredGood, getWorkshopNumberOfWorkplaces, and --- getWorkshopRecipe with an index desired, which is good for loops. If you --- must get the tables, there are two "getAll" methods: --- --- * requiredGoodsTable = WorkshopsData.getAllWorkshopRequiredGoods(workshopName) --- * workplacesTable = WorkshopsData.getAllWorkshopWorkplaces(workshopName) --- * recipesTable = WorkshopsData.getAllWorkshopRecipes(workshopName) --- --- As a last resort, or if you need to transform the data structure, you can --- call the method getAllDataForWorkshop(displayName) or --- getAllDataForWorkshopByID(workshopID). This returns a whole record from the --- data table corresponding to the requested display name. --- --- The data table for workshops has the following structure: --- --- workshopsTable = { --- 	["workshop1_ID"] = { --- 		["id"] = "workshop1_ID", --- 		["displayName"] = "Plain Language Name", --- 		["description"] = "A long string with some HTML entities too.", --- 		["category"] = "Construction toolbar category", --- 		["sizeX"] = 9, size in tiles --- 		["sizeY"] = 9, size in tiles --- 		["requiredGoods"] = { ---				[1] = { ["stackSize"] = 99, ["goodID"] = "good1_ID" }, --- 			[2] = { ["stackSize"] = 99, ["goodID"] = "good2_ID" }, --- 			[3] = { ... } or missing if fewer --- 		}, --- 		["constructionTime"] = 99, number of seconds --- 		["cityScore"] = 99, points? --- 		["movable"] = true or false, if it can be moved at any cost --- 		["initiallyEssential"] = true or false, if a new-game-starting blueprint --- 		["storage"] = 99, capacity --- 		["workplaces"] = { --- 			[1] = "Any", --- 			[2] = "Any", --- 			[3] = "Any", --- 			[4] = ... representing the number of workplaces, or missing if fewer --- 		}, --- 		["recipes"] = { --- 			[1] = "recipe1_ID", --- 			[2] = "recipe2_ID", --- 			[3] = "recipe3_ID", --- 			[4] = ... or missing if fewer --- 		} --- 	}, --- 	["workshop2_ID"] = { --- 		... --- 	}, ---		["workshop3_ID"] = { --- 		... --- 	}, --- 	... --- } --- --- @module WorkshopsData local WorkshopsData = {}
