Module:BuildingLink

--- -- This module renders the template. -- https://hoodedhorse.com/wiki/Against_the_Storm/Template:Building_link -- -- The template #invokes BuildingLink.renderLink(frame), below. -- -- The template requires an argument, the name of the building to which to link. -- Optionally, the template accepts a second argument to render an icon next to -- the link. The building is passed to Module:WorkshopsData, which is used to -- identify the wiki page to link to. -- -- Using the data returned, this module creates an icon and the name of the -- building, and wraps both in a link to the building's wiki page. If no icon -- size is specified, only the name of the building will be rendered by the -- template. -- -- The icons are sized consistently by using existing wiki templates, , --, etc. The sizes of the icons are not stored or known by this module. -- @module BuildingLink local BuildingLink = {}

--- -- Dependencies -- local WorkshopsData = require("Module:WorkshopsData")

--- -- Main rendering function -- -- Renders an icon the name of a building linked to a wiki page corresponding -- to the provided building. -- -- Uses MediaWiki markup to display the name of a wiki page and an icon that has -- been uploaded to the wiki. Both must be known by Module:BuildingData, or the -- template's behavior may be different than expected. -- @param frame the template's calling context, with parameters -- @return wiki markup function BuildingLink.renderLink(frame) -- Extract the template parameters. local argBuildingName = frame.args.building local argIconsize = frame.args.iconsize -- Validate that there's a name to use if not argBuildingName or "" == argBuildingName then return "The Building Link template requires the a name of a building." end
