Module:SpecializationLink

--- -- This module renders the template. -- https://hoodedhorse.com/wiki/Against_the_Storm/Template:Specialization_link -- -- This template #invokes SpecializationLink.renderLink(frame), below. -- -- The template requires an argument, the name of the specialization to which to -- link. Optionally, the template accepts a second argument to change the size -- of the icon that accompanies the text hyperlink. -- -- Using the arguments, this module creates an icon and the name of the -- specialization, and wraps both in a link to the specialization'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 SpecializationLink local SpecializationLink = {}
