ਮੌਡਿਊਲ:ਫਾਟਕ

--[==[ 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.ਫਾਟਕ, which generates a table of ਫਾਟਕs, and p.image, which -- produces the image name for an individual ਫਾਟਕ.

-- The ਫਾਟਕ image data is kept in submodules of Module:ਫਾਟਕl/images, listed below: -- Module:ਫਾਟਕ/images/a - for ਫਾਟਕ names beginning with "A". -- Module:ਫਾਟਕ/images/b - for ਫਾਟਕ names beginning with "B". -- Module:ਫਾਟਕ/images/c - for ਫਾਟਕ names beginning with "C". -- Module:ਫਾਟਕ/images/d - for ਫਾਟਕ names beginning with "D". -- Module:ਫਾਟਕ/images/e - for ਫਾਟਕ names beginning with "E". -- Module:ਫਾਟਕ/images/f - for ਫਾਟਕ names beginning with "F". -- Module:ਫਾਟਕ/images/g - for ਫਾਟਕ names beginning with "G". -- Module:ਫਾਟਕ/images/h - for ਫਾਟਕ names beginning with "H". -- Module:ਫਾਟਕ/images/i - for ਫਾਟਕ names beginning with "I". -- Module:ਫਾਟਕ/images/j - for ਫਾਟਕ names beginning with "J". -- Module:ਫਾਟਕ/images/k - for ਫਾਟਕ names beginning with "K". -- Module:ਫਾਟਕ/images/l - for ਫਾਟਕ names beginning with "L". -- Module:ਫਾਟਕ/images/m - for ਫਾਟਕ names beginning with "M". -- Module:ਫਾਟਕ/images/n - for ਫਾਟਕ names beginning with "N". -- Module:ਫਾਟਕ/images/o - for ਫਾਟਕ names beginning with "O". -- Module:ਫਾਟਕ/images/p - for ਫਾਟਕ names beginning with "P". -- Module:ਫਾਟਕ/images/q - for ਫਾਟਕ names beginning with "Q". -- Module:ਫਾਟਕ/images/r - for ਫਾਟਕ names beginning with "R". -- Module:ਫਾਟਕ/images/s - for ਫਾਟਕ names beginning with "S". -- Module:ਫਾਟਕ/images/t - for ਫਾਟਕ names beginning with "T". -- Module:ਫਾਟਕ/images/u - for ਫਾਟਕ names beginning with "U". -- Module:ਫਾਟਕ/images/v - for ਫਾਟਕ names beginning with "V". -- Module:ਫਾਟਕ/images/w - for ਫਾਟਕ names beginning with "W". -- Module:ਫਾਟਕ/images/x - for ਫਾਟਕ names beginning with "X". -- Module:ਫਾਟਕ/images/y - for ਫਾਟਕ names beginning with "Y". -- Module:ਫਾਟਕ/images/z - for ਫਾਟਕ names beginning with "Z". -- Module:ਫਾਟਕ/images/other - for ਫਾਟਕ names beginning with any other letters. This includes numbers, -- letters with diacritics, and letters in non-Latin alphabets. -- Module:ਫਾਟਕ/images/aliases - for adding aliases for existing ਫਾਟਕ names. Use this page for variations -- in spelling and diacritics, etc., no matter what letter the ਫਾਟਕ 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:ਫਾਟਕ/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. ]==]
