Module:InstitutionsData

--- --- Module for compiling service-buildings 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: --- --- sizeX, sizeY = InstitutionsData.getInstitutionSize(institutionName) --- --- This will return the 2 x 2 size of the institution. It is preferable to --- call the getter methods with the name of the institution rather than --- retrieving the entire data record for the institution. This way your code --- stays protected from variations in this module. These getter methods are --- called with the plain-language display name of the institution, as spelled --- in the game, including punctuation. --- --- * longDescription = InstitutionsData.getInstitutionDescription(institutionName) --- * constructionCategory = InstitutionsData.getInstitutionCategory(institutionName) --- * sizeX, sizeY = InstitutionsData.getInstitutionSize(institutionName) --- * requiredGoodID, stackSize = InstitutionsData.getInstitutionRequiredGood(institutionName, requirementIndex) --- * timeSeconds = InstitutionsData.getInstitutionConstructionTime(institutionName) --- * cityScore = InstitutionsData.getInstitutionCityScore(institutionName) --- * isMovable = InstitutionsData.isInstitutionMovable(institutionName) --- * isInitiallyEssential = InstitutionsData.isInstitutionInitiallyEssential(institutionName) --- * workplaces = InstitutionsData.getInstitutionNumberOfWorkplaces(institutionName) --- * recipe = InstitutionsData.getInstitutionRecipe(institutionName, recipeIndex) --- * iconFilename = InstitutionsData.getInstitutionIcon(institutionName) --- --- And the following getter methods are all called with the institution's ID. --- You will have an ID instead of a display name when dealing with other data --- like recipes, species, etc. --- --- * name = InstitutionsData.getInstitutionNameByID(institutionID) --- * iconFilename = InstitutionsData.getInstitutionIconByID(institutionID) --- --- There are methods to retrieve the lists of required goods, workplaces, and --- recipes, but it is advised to instead use the getter methods --- getInstitutionRequiredGood, getInstitutionNumberOfWorkplaces, and --- getInstitutionRecipe with an index desired, which is good for loops. If --- you must get the tables, there are three "getAll" methods: --- --- * requiredGoodsTable = InstitutionsData.getAllInstitutionRequiredGoods(institutionName) --- * workplacesTable = InstitutionsData.getAllInstitutionWorkplaces(institutionName) --- * recipesTable = InstitutionsData.getAllInstitutionRecipes(institutionName) --- --- As a last resort, or if you need to transform the data structure, you can --- call the method getAllDataForInstitution(institutionName) or --- getAllDataForInstitutionByID(institutionID). These return a whole record --- from the data table corresponding to the required display name or ID. --- --- The data table for institutions has the following structure: --- --- institutionsTable = { --- 	["institution1_ID"] = { --- 		["id"] = "institution1_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 --- 		["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 --- 		} --- 	}, --- 	["institution2_ID"] = { --- 		... --- 	}, --- 	["institution3_ID"] = { --- 		... --- 	}, --- 	... --- } --- --- @module InstitutionsData local InstitutionsData = {}
