Module:Format link/doc

This module, migrated from origins in Module:Hatnote, provides functionality for formatting links for display, including that powering the {{format link}} template.

It can pretty-format section links with the section symbol ("§") and appropriate whitespace, it automatically escapes category and file names with the colon trick, and includes functionality for italicizing the page or section name, and for detecting and categorizing results that produce red links.

Use from wikitext

The functions in this module cannot be used directly from #invoke, and must be used through templates instead. Please see Template:Format link for documentation on usage of that template.

Use from other Lua modules

To load this module from another Lua module, use the following code:

<syntaxhighlight lang="lua"> local mFormatLink = require('Module:Format link') </syntaxhighlight>

You can then use the functions as documented below.

_formatLink

<syntaxhighlight lang="lua"> mFormatLink._formatLink{

   link = link,
   display = display,
   italicizePage = true,
   italicizeSection = true,
   categorizeMissing = 'Pages using formatted red links'

} </syntaxhighlight>

Formats link as a wikilink, with optional display value display. Categories and files are automatically escaped with the colon trick, and links to sections are automatically formatted as page § section, rather than the MediaWiki default of page#section. If manual piping is present in link, then the "manual" display value will be overridden by the display value if present.

If italicizePage is true then the page portion of the link is italicized, and if italicizeSection is true then the section portion of the link is italicized. If categorizeMissing is a string, then that value is used as a category name, and that category will be applied if the target of the link doesn't exist.

Examples

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'Foo#Bar'}</syntaxhighlight> → [[:Foo#Bar|Foo §&nbsp;Bar]] → Foo § Bar

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'Baz', display = 'Qux'}</syntaxhighlight> → [[:Baz|Qux]] → Qux

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'Foo|Bar', display = 'Baz'}</syntaxhighlight> → [[:Foo|Baz]] → Baz

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'Nonexistent page', categorizeMissing = 'Example'}</syntaxhighlight> → [[:Nonexistent page]][[Category:Example]] → Nonexistent page

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'Existing', categorizeMissing = 'Example'}</syntaxhighlight> → [[:Existing]] → Existing

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'The Lord of the Rings#Plot', italicizePage = true}</syntaxhighlight> → [[:The Lord of the Rings#Plot|''The Lord of the Rings'' §&nbsp;Plot]] → The Lord of the Rings § Plot

<syntaxhighlight lang="lua" inline>mFormatLink._formatLink{link = 'Cybercrime Prevention Act of 2012#Disini v. Secretary of Justice', italicizeSection = true}</syntaxhighlight> → [[:Cybercrime Prevention Act of 2012#Disini v. Secretary of Justice|Cybercrime Prevention Act of 2012 §&nbsp;''Disini v. Secretary of Justice'']] → Cybercrime Prevention Act of 2012 § Disini v. Secretary of Justice

formatPages

<syntaxhighlight lang="lua"> mFormatLink.formatPages(options, pages) </syntaxhighlight>

This derived function is useful for lists that format many links. It formats an array of pages using the _formatLink function, and returns the result as an array. Options in the options table are applied, and use the same names as the options for _formatLink.

Example

<syntaxhighlight lang="lua" class="" id="" style="" inline="1">mFormatLink.formatPages({categorizeMissing = 'Example'}, {'Foo#Bar', 'Nonexistent page'})</syntaxhighlight> → <syntaxhighlight lang="lua" class="" id="" style="" inline="1">{'[[:Foo#Bar|Foo § Bar]]', '[[:Nonexistent page]][[Category:Example]]'}</syntaxhighlight>
