--[==[ This module is a Lua implementation of the old template. As of August 2013 it is used on nearly 5,000,000 articles.-- 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.]==]local htmlBuilder = require('Module:HtmlBuilder')local p = {}local function matchImagePage(s) -- Finds the appropriate image subpage given a lower-case -- portal name plus the first letter of that portal name. if type(s) ~= 'string' or #s < 1 then return end local firstLetter = mw.ustring.sub(s, 1, 1) local imagePage if mw.ustring.find(firstLetter, '^[a-z]') then imagePage = 'Module:Portal/images/' .. firstLetter else imagePage = 'Module:Portal/images/other' end return mw.loadData(imagePage)[s]endlocal function getAlias(s) -- Gets an alias from the image alias data page. local aliasData = mw.loadData('Module:Portal/images/aliases') for portal, aliases in pairs(aliasData) do for _, alias in ipairs(aliases) do if alias == s then return portal end end endendlocal function getImageName(s) -- Gets the image name for a given string. local default = 'Portal-puzzle.svg|link=|alt=' if type(s) ~= 'string' or #s < 1 then return default end s = mw.ustring.lower(s) return matchImagePage(s) or matchImagePage(getAlias(s)) or defaultendfunction p._portal(portals, args) -- This function builds the portal box used by the template. local root = mw.html.create('div') :attr('role', 'navigation') :attr('aria-label', 'Portals') :addClass('noprint portal plainlist') :addClass(args.left and 'tleft' or 'tright') :css('margin', args.margin or (args.left == 'yes' and '0.5em 1em 0.5em 0') or '0.5em 0 0.5em 1em') :css('border', 'solid #aaa 1px') :newline() -- If no portals have been specified, display an error and add the page to a tracking category. if not portals[1] then root:wikitext('No portals specified: please specify at least one portal') return tostring(root) end -- Start the list.
