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 link to. --- 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 = {}
