وحدة:Main
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 used 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(options, ...)
The parameters following options are a list of link/display tables, used to generate the links. The first value in each table is the link, and is required. The second value in each table is the display value, and is optional. 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 options table can be used to configure the function's output. At current, the only option available is "selfref", which is used when the output is a self-reference to Wikipedia. to set this option, use
. (See the {{selfref}} template for more details on self-references.)
{selfref = true}
- Example 1
mMain._main(nil, {'A'})
Produces:
<div class="hatnote relarticle mainarticle">Main article: [[A]]</div>
Displays as:
- Example 2
mMain._main(nil, {'المعرفة:تصنيف'}, {'مساعدة:تصنيف'}, {'تصنيف:تصنيفات المعرفة'})
Produces:
<div class="hatnote relarticle mainarticle">Main pages: [[المعرفة:تصنيف]], [[مساعدة:تصنيف]] and [[:تصنيف:تصنيفات المعرفة]]</div>
Displays as:
- Example 3
mMain._main(nil, {'A', 'the letter "A"'}, {'B', 'the letter "B"'}, {'C', 'the letter "C"'})
Produces:
<div 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({selfref = true}, {'Wikipedia:Verifiability#Burden'})
Produces:
<div class="hatnote relarticle mainarticle selfref">Main article: [[Wikipedia:Verifiability#Burden|Wikipedia:Verifiability § Burden]]</div>
Displays as:
- Example 5 (if used in the category namespace)
mMain._main(nil, {'A'})
Produces:
<div class="hatnote relarticle mainarticle">المقالة الرئيسية لهذا [[المعرفة:تصنيف|التصنيف]] هي [[A]]</div>

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