Module:Disambiguation

Template:Module rating 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}} →
• {{#invoke:Disambiguation|isDisambiguationPage|Black swan (disambiguation)}} → yes

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

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

Usage within Lua modules

Import this module, e.g with <syntaxhighlight lang="lua"> local mDisambiguation = require('Module:Disambiguation') </syntaxhighlight> 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: <syntaxhighlight lang="lua"> local isDab = mDisambiguation.isDisambiguation(content) -- returns true or false </syntaxhighlight>

(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: <syntaxhighlight lang="lua"> local isDab = mDisambiguation._isDisambiguationPage(pageName) -- returns true or false </syntaxhighlight>

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