Module:Portal
මෙම Lua module පිටු 8,470,000 පමණ pages, or roughly 5464% of all භාවිතා වන නිසා. To avoid major disruption and server load, any changes should be tested in the මෙම මොඩියුලයට අදාළ /sandbox හෝ /testcases උපපිටු. The tested changes can be added to this page in a single edit. එම වෙනස්කම් සිදුකිරීමට ප්රථම අදාළ සාකච්ඡා පිටුවේ ඒ පිළිබඳව සංවාදයක් ගොඩනැගීමට කාරුණික වන්න. Transclusion count updated automatically (ප්රලේඛනය වෙතට යොමුවන්න). |
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |

This module has two functions, portal
and image
. The portal
produces a box with links to a portal or to multiple portals, and is used by the {{portal}} template. It is most often used in the "See also" section of an article. The image
function produces the name of the image used by the specified portal.
Portal function
[සංස්කරණය]The portal function produces a box of portal links. සැකිල්ල:Portal/doc
Image function
[සංස්කරණය]The image function produces the name of the image used by the specified portal.
Usage
[සංස්කරණය]{{#invoke:Portal|image|portal}}
Example
[සංස්කරණය]{{#invoke:Portal|image|Art}}
→ Ballerina-icon.jpg
Image dupes function
[සංස්කරණය]The image dupes function returns a list of all images that are being used by more than one portal (aliases are not included). This can be helpful in identifying image entries that should be changed to use aliases.
Usage
[සංස්කරණය]{{#invoke:Portal|imageDupes}}
Display all function
[සංස්කරණය]The display all function returns a box containing all portals that have images. This is used for maintenance, and should not be displayed in articles, because a) there are around 1500 portals with images, and displaying 1500 images on one page takes up a lot of server resources, and b) the module has no way to know the correct capitalisation of a portal name, so some links to portals will be broken. This function can be seen at Template:Portal/doc/all.
Usage
[සංස්කරණය]{{#invoke:Portal|displayAll}}
--[==[ This module is a Lua implementation of the old {{Portal}} template. As of February 2019 it is used on nearly 7,900,000 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.
