This Lua module is used on approximately 220,000 pages. 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. Consider discussing changes on the talk page before implementing them.

This module depends on the following other modules: Module:Hatnote (sandbox) Module:Format link (sandbox) Module:Yesno (sandbox) Module:TableTools (sandbox) Module:Arguments (sandbox)

This module produces hatnote saying "The main article for this category is x." It implements the {{Category main article}} template.

This module should usually be used via the {{Category main article}} template. However, it can also be used from #invoke with the syntax {{#invoke:Category main article|catMain|parameters}}. Please see the {{Category main article}} template documentation for available parameters.

Load the module:

local mCatMain = require('Module:Category main article')

You can then use the _catMain function like this:

mCatMain._catMain(options, ...)

options is an optional table that can be used to configure the function's output. There are two available options, "article" and "selfref".

• article - if this is set to false, "no", "n", "false", or 0, the module outputs "The main page" rather than "The main article". Use the code {article = false}.
• selfref - this is used when the output is a self-reference to Wikipedia. To set this option, use {selfref = true}. (See the {{selfref}} template for more details on self-references.)

The remaining arguments are page names to be turned into link(s) following the text "The main article for this category is". If no page names are specified, the current page name (minus the namespace name) is used for the first link.

Example 1

mCatMain._catMain(nil, 'Foo')

Produces:

<div class="hatnote relarticle mainarticle">The main article for this [[Help:Categories|category]] is '''[[Foo]]'''.</div>

Displays as:

Example 2

mCatMain._catMain(nil, 'Foo', 'Bar', 'Baz')

Produces:

<div class="hatnote relarticle mainarticle">The main articles for this [[Help:Categories|category]] are '''[[Foo]]''', '''[[Bar]]''' and '''[[Baz]]'''.</div>

Displays as:

Example 3

mCatMain._catMain({article = false}, 'Foo')

Produces:

<div class="hatnote relarticle mainarticle">The main page for this [[Help:Categories|category]] is '''[[Foo]]'''.</div>

Displays as:

This module uses Module:Hatnote to format the hatnote text.

This module has five lines that must be translated when exported to wikis in other languages.
