Modul:Hatnote
This Lua module is used in MediaWiki:Wantedpages-summary. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption, 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. Please discuss changes on the talk page before implementing them. |
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |

Lua error in Modul:TNT at line 159: Missing JsonConfig extension; Cannot load https://commons.wikimedia.org/wiki/Data:I18n/Uses TemplateStyles.tab. This is a meta-module that provides various functions for making hatnotes. It implements the {{hatnote}} template, for use in hatnotes at the top of pages, and the {{format link}} template, which is used to format a wikilink for use in hatnotes. It also contains a number of helper functions for use in other Lua hatnote modules.
Use from wikitext
The functions in this module cannot be used directly from #invoke, and must be used through templates instead. Please see Template:Hatnote and Template:Format link for documentation.
Use from other Lua modules
To load this module from another Lua module, use the following code.
<syntaxhighlight lang="lua"> local mHatnote = require('Module:Hatnote') </syntaxhighlight>
You can then use the functions as documented below.
Hatnote
<syntaxhighlight lang="lua"> mHatnote._hatnote(s, options) </syntaxhighlight>
Formats the string s as a hatnote. This encloses s in the tags <div class="hatnote">...</div>
. Options are provided in the options table. Options include:
- options.extraclasses - a string of extra classes to provide
- options.selfref - if this is not nil or false, adds the class "selfref", used to denote self-references to Wikipedia (see Template:Selfref))
The CSS of the hatnote class is defined in MediaWiki:Common.css.
- Example 1
<syntaxhighlight lang="lua"> mHatnote._hatnote('This is a hatnote.') </syntaxhighlight>
Produces:
<div class="hatnote">This is a hatnote.</div>
Displays as:
- Example 2
<syntaxhighlight lang="lua"> mHatnote._hatnote('This is a hatnote.', {extraclasses = 'boilerplate seealso', selfref = true}) </syntaxhighlight>
Produces:
<div class="hatnote boilerplate seealso selfref">This is a hatnote.</div>
Displayed as:
Format link
<syntaxhighlight lang="lua"> mHatnote._formatLink{link = link, display = display, italicizePage = true, italicizeSection = true} </syntaxhighlight>
Formats link as a wikilink for display in hatnote templates, 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 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.
- Examples
- <syntaxhighlight lang="lua" inline>mHatnote._formatLink{link = 'Lion'}</syntaxhighlight> → [[Lion]] → Lion
- <syntaxhighlight lang="lua" inline>mHatnote._formatLink{link = 'Lion#Etymology'}</syntaxhighlight> → [[Lion#Etymology|Lion § Etymology]] → Lion § Etymology
- <syntaxhighlight lang="lua" inline>mHatnote._formatLink{link = 'Category:Lions'}</syntaxhighlight> → [[:Category:Lions]] → Category:Lions
- <syntaxhighlight lang="lua" inline>mHatnote._formatLink{link = 'Lion#Etymology', display = 'Etymology of lion'}</syntaxhighlight> → [[Lion#Etymology|Etymology of lion]] → Etymology of lion
- <syntaxhighlight lang="lua" inline>mHatnote._formatLink{link = 'Quo warranto#Philippines', italicizePage = true}</syntaxhighlight> → [[Quo warranto#Philippines|<i>Quo warranto</i> § Philippines]] → Quo warranto § Philippines
- <syntaxhighlight lang="lua" inline>mHatnote._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 § <i>Disini v. Secretary of Justice</i>]] → Cybercrime Prevention Act of 2012 § Disini v. Secretary of Justice
Format pages
<syntaxhighlight lang="lua"> mHatnote.formatPages(...) </syntaxhighlight>
Formats a list of pages using the _formatLink function, and returns the result as an array. For example, the code <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.formatPages('Lion', 'Category:Lions', 'Lion#Etymology')</syntaxhighlight> would produce an array like <syntaxhighlight lang="lua" class="" id="" style="" inline="1">{'Lion', 'Category:Lions', 'Lion § Etymology'}</syntaxhighlight>.
Format page tables
<syntaxhighlight lang="lua"> mHatnote.formatPageTables(...) </syntaxhighlight>
Takes a list of page/display tables, formats them with the _formatLink function, and returns the result as an array. Each item in the list must be a table. The first value in the table is the link, and is required. The second value in the table is the display value, and is optional. For example, the code <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.formatPages({'Lion', 'the Lion article'}, {'Category:Lions'}, {'Lion#Etymology', 'the etymology of lion'})</syntaxhighlight> would produce an array like <syntaxhighlight lang="lua" class="" id="" style="" inline="1">{'the Lion article', 'Category:Lions', 'the etymology of lion'}</syntaxhighlight>.
Find namespace id
<syntaxhighlight lang="lua"> mHatnote.findNamespaceId(link, removeColon) </syntaxhighlight>
Finds the namespace id of the string link, which should be a valid page name, with or without the section name. This function will not work if the page name is enclosed with square brackets. When trying to parse the namespace name, colons are removed from the start of the link by default. This is helpful if users have specified colons when they are not strictly necessary. If you do not need to check for initial colons, set removeColon to false.
- Examples
- <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.findNamespaceId('Lion')</syntaxhighlight> → 0
- <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.findNamespaceId('Category:Lions')</syntaxhighlight> → 14
- <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.findNamespaceId(':Category:Lions')</syntaxhighlight> → 14
- <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.findNamespaceId(':Category:Lions', false)</syntaxhighlight> → 0 (the namespace is detected as ":Category", rather than "Category")
Make wikitext error
<syntaxhighlight lang="lua"> mHatnote.makeWikitextError(msg, helpLink, addTrackingCategory) </syntaxhighlight>
Formats the string msg as a red wikitext error message, with optional link to a help page helpLink. Normally this function also adds Category:Hatnote templates with errors (0). To suppress categorization, pass false
as third parameter of the function (addTrackingCategory
).
Examples:
- <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.makeWikitextError('an error has occurred')</syntaxhighlight> → Error: an error has occurred.
- <syntaxhighlight lang="lua" class="" id="" style="" inline="1">mHatnote.makeWikitextError('an error has occurred', 'Template:Example#Errors')</syntaxhighlight> → Error: an error has occurred (help).
