This module has two functions,portal
andimage
.Theportal
produces a box with links to aportalor to multiple portals, and is used by the {{portal}} template. It is most often used in the "See also" section of an article. Theimage
function produces the name of the image used by the specified portal.
Portal function
[édit sumber]The portal function produces a box of portal links.
Cara make
[édit sumber]This template is used to link an article to its relatedportal.
- Optional parameters
{{Portal|name|image|size|boxsize|break=yes}}
Lokasi
[édit sumber]This template is meant to be placed at the bottom of the article in the "See also" section.
Image function
[édit sumber]The image function produces the name of the image used by the specified portal.
Usage
[édit sumber]{{#invoke:Portal|image|portal}}
Example
[édit sumber]{{#invoke:Portal|image|Art}}
→ Ballerina-icon.jpg
Image dupes function
[édit sumber]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
[édit sumber]{{#invoke:Portal|imageDupes}}
Display all function
[édit sumber]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 atTemplate:Portal/doc/all.
Usage
[édit sumber]{{#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.
