Module:Main/doc
 | This Lua module is used on a very large number of pages. To avoid large-scale disruption and unnecessary server load, any changes to this module should first be tested in its /sandbox or /testcases subpages. The tested changes can then be added to this page in one single edit. Please consider discussing any changes on the talk page before implementing them. |
This module produces a link to a main article or articles. It implements the {{main}} template. Normally, it produces a link like "Main article: A". If used in the category namespace, it produces a link like "The main article for this category is A". It is possible to specify multiple articles, and in this case plural wording is used automatically. If the first link is not an article, the module uses the wording "Main page" instead of "Main article".
Usage from wikitext
This module cannot be accessed directly from #invoke. Instead, it can only be used through the {{main}} template. Please see the template page for documentation.
Usage from other Lua modules
Load the module:
local mMain = require('Module:Main')
You can then use the _main function like this:
mMain._main(args, options)
The args parameter following options are a list of page link strings; if they use custom display values, each string should be preprocessed into a single piped string (e.g. page|display value). Category or file links are automatically escaped using the colon trick. If a link includes a section name, and no display value is set, links are automatically formatted as page § section, rather than the MediaWiki default of page#section.
The optional options table can be used to configure the function's output. At present, the only option available is "selfref", which is used when the output is a self-reference to WikiDevi. to set this option, use {selfref = true}. (See the {{selfref}} template for more details on self-references.)
Example 1
mMain._main({'A'})
Produces:
<div role="note" class="hatnote relarticle mainarticle">Main article: [[A]]</div>
Displays as:
Example 2
mMain._main({'WikiDevi:Categorization', 'Help:Category', 'Category:WikiDevi categories'})
Produces:
<div role="note" class="hatnote relarticle mainarticle">Main pages: [[WikiDevi:Categorization]], [[Help:Category]] and [[:Category:WikiDevi categories]]</div>
Displays as:
Example 3
mMain._main({'A|the letter "A"', 'B|the letter "B"', 'C|the letter "C"'})
Produces:
<div role="note" class="hatnote relarticle mainarticle">Main articles: [[A|the letter "A"]], [[B|the letter "B"]] and [[C|the letter "C"]]</div>
Displays as:
Example 4
mMain._main({'WikiDevi:Verifiability#Burden'}, {selfref = true})
Produces:
<div role="note" class="hatnote relarticle mainarticle selfref">Main article: [[WikiDevi:Verifiability#Burden|WikiDevi:Verifiability § Burden]]</div>
Displays as:
Example 5 (if used in the category namespace)
mMain._main({'A'})
Produces:
<div role="note" class="hatnote relarticle mainarticle">The main article for this [[WikiDevi:Categorization|category]] is [[A]]</div>

Technical details
This module uses Module:Hatnote to format the hatnote text, Module:Hatnote list to process the list of links, and Module:Arguments to fetch the arguments from wikitext.
