Module:ResourceLink

--- -- This module renders the template. -- https://hoodedhorse.com/wiki/Against_the_Storm/Template:Resource_link -- -- This template #invokes ResourceLink.renderLink(frame), below. -- -- The template requires an argument, the name of the resource to which to link. -- Optionally, the template accepts a second argument to change the size of the -- icon that accompanies the text hyperlink. The resource is passed to -- Module:GoodsData, 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 -- resource, and wraps both in a link to the resource's wiki page. If no icon -- size is specified, the icon will default to a size appropriate for display -- in-line with other text. -- -- The icons are sized consistently by using existing wiki templates, , --, etc. The sizes of icons are not stored or known by this module. -- @module ResourceLink local ResourceLink = {}

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

--- -- Main rendering function -- -- Renders an icon the name of a resource linked to a wiki page corresponding -- to the provided resource. -- -- Uses MediaWiki markup to display the name of a wiki page and an icon that has -- been uploaded to the wiki.
