Module:Disambiguation/doc

This Lua module is used in system messages, and on approximately 213,000 pages.
Changes to it can cause immediate changes to the Wikipedia user interface.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.

This module depends on the following other modules:

Module:Redirect (sandbox)

This module detects if a given page is a disambiguation page.

Usage

{{#invoke:Disambiguation|isDisambiguationPage|Page title}}

returns yes if the page is a disambiguation page, or nothing if the page is not a disambiguation page

Examples:

{{#invoke:Disambiguation|isDisambiguationPage|Paris}} →
{{#invoke:Disambiguation|isDisambiguationPage|New}} → yes
{{#invoke:Disambiguation|isDisambiguationPage|Black swan (disambiguation)}} → yes

You can also use magic words like {{SUBJECTPAGENAME}}:

{{#invoke:Disambiguation|isDisambiguationPage|{{SUBJECTPAGENAME}}}} →

Usage within Lua modules

Import this module, e.g with

local mDisambiguation = require('Module:Disambiguation')

Then you can use the functions isDisambiguation and _isDisambiguationPage.

If you have already have a Title object for the page to check, get the content using the title object's getContent() method, and pass that into isDisambiguation:

local isDab = mDisambiguation.isDisambiguation(content) -- returns true or false

(where content is a string, the wikitext content of page to check)

If you don't otherwise need the title, you can pass in the page name to _isDisambiguationPage:

local isDab = mDisambiguation._isDisambiguationPage(pageName) -- returns true or false

(where pageName is a string, the name of page to check)

Internal operations

Although set index articles are treated by some templates as disambiguation pages, they are actually considered a special type of list and are not treated as disambiguation pages by this module
As this module relies on detecting templates with names like "disambiguation" in the article text, it is subject to false positives by templates such as {{italic disambiguation}}. These templates should be added to the falsePositives list in the code to exclude them.
The list of disambiguation templates is maintained at Module:Disambiguation/templates.
