update and remove HtmlBuilder
Baris 1:
--[==[ This module is a Lua implementation of the old {{Portal}} template. As of August 2013 it is used on nearly 5,000,000 articles.
-- This module implements {{Portal}}
-- Please take care when updating it! It outputs two functions: p.portal, which generates a list of portals, and p.image, which
-- produces the image name for an individual portal.
 
-- The portal image data is kept in submodules of [[Module:Portal/images]], listed below:
-- [[Module:Portal/images/a]] - for portal names beginning with "A".
-- [[Module:Portal/images/b]] - for portal names beginning with "B".
-- [[Module:Portal/images/c]] - for portal names beginning with "C".
-- [[Module:Portal/images/d]] - for portal names beginning with "D".
-- [[Module:Portal/images/e]] - for portal names beginning with "E".
-- [[Module:Portal/images/f]] - for portal names beginning with "F".
-- [[Module:Portal/images/g]] - for portal names beginning with "G".
-- [[Module:Portal/images/h]] - for portal names beginning with "H".
-- [[Module:Portal/images/i]] - for portal names beginning with "I".
-- [[Module:Portal/images/j]] - for portal names beginning with "J".
-- [[Module:Portal/images/k]] - for portal names beginning with "K".
-- [[Module:Portal/images/l]] - for portal names beginning with "L".
-- [[Module:Portal/images/m]] - for portal names beginning with "M".
-- [[Module:Portal/images/n]] - for portal names beginning with "N".
-- [[Module:Portal/images/o]] - for portal names beginning with "O".
-- [[Module:Portal/images/p]] - for portal names beginning with "P".
-- [[Module:Portal/images/q]] - for portal names beginning with "Q".
-- [[Module:Portal/images/r]] - for portal names beginning with "R".
-- [[Module:Portal/images/s]] - for portal names beginning with "S".
-- [[Module:Portal/images/t]] - for portal names beginning with "T".
-- [[Module:Portal/images/u]] - for portal names beginning with "U".
-- [[Module:Portal/images/v]] - for portal names beginning with "V".
-- [[Module:Portal/images/w]] - for portal names beginning with "W".
-- [[Module:Portal/images/x]] - for portal names beginning with "X".
-- [[Module:Portal/images/y]] - for portal names beginning with "Y".
-- [[Module:Portal/images/z]] - for portal names beginning with "Z".
-- [[Module:Portal/images/other]] - for portal names beginning with any other letters. This includes numbers,
-- letters with diacritics, and letters in non-Latin alphabets.
-- [[Module:Portal/images/aliases]] - for adding aliases for existing portal names. Use this page for variations
-- in spelling and diacritics, etc., no matter what letter the portal begins with.
--
-- The images data pages are separated by the first letter to reduce server load when images are added, changed, or removed.
-- Previously all the images were on one data page at [[Module:Portal/images]], but this had the disadvantage that all
-- 5,000,000 pages using this module needed to be refreshed every time an image was added or removed.
