Mô đun:User

--[=[-- This module implements {{user}}. {{user}} is a high-use template, sometimes-- with thousands of transclusions on a page. This module optimises the-- template's performance by reducing the number of parameters called from-- wikitext, while still allowing all the features provided by-- [[Mô đun:UserLinks]]. It is about twice as fast as the version of {{user}}-- that called the {{user-multi}} template from wikitext.--]=]local mUserLinks = require('Mô đun:UserLinks')local mShared = require('Mô đun:UserLinks/shared')local yesno = require('Mô đun:Yesno')local p = {}local function validateArg(arg) -- Validates one argument.
