This Lua module is used on १०,००,०००+ pages, or roughly 1283% of all 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 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

[सम्पादयतु]

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

[सम्पादयतु]

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

local mHatnote = require('Module:Hatnote')

You can then use the functions as documented below.

Hatnote

[सम्पादयतु]

mHatnote._hatnote(s, options)

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

mHatnote._hatnote('This is a hatnote.')

Produces: <div class="hatnote">This is a hatnote.</div>

Displays as:

This is a hatnote.

Example 2

mHatnote._hatnote('This is a hatnote.', {extraclasses = 'boilerplate seealso', selfref = true})

Produces: <div class="hatnote boilerplate seealso selfref">This is a hatnote.</div>

Displayed as:

This is a hatnote.

Format link

[सम्पादयतु]

mHatnote._formatLink(link, display)

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.

Examples: mHatnote._formatLink('Lion') → [[Lion]] → Lion; mHatnote._formatLink('Lion#Etymology') → [[Lion#Etymology|Lion § Etymology]] → Lion § Etymology; mHatnote._formatLink('Category:Lions') → [[:Category:Lions]] → Category:Lions; mHatnote._formatLink('Lion#Etymology', 'Etymology of lion') → [[Lion#Etymology|Etymology of lion]] → Etymology of lion

Format pages

[सम्पादयतु]

mHatnote.formatPages(...)

Formats a list of pages using the _formatLink function, and returns the result as an array. For example, the code mHatnote.formatPages('Lion', 'Category:Lions', 'Lion#Etymology') would produce an array like {'[[Lion]]', '[[:Category:Lions]]', '[[Lion#Etymology|Lion § Etymology]]'}.

Format page tables

[सम्पादयतु]

mHatnote.formatPageTables(...)

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 mHatnote.formatPages({'Lion', 'the Lion article'}, {'Category:Lions'}, {'Lion#Etymology', 'the etymology of lion'}) would produce an array like {'[[Lion|the Lion article]]', '[[:Category:Lions]]', '[[Lion#Etymology|the etymology of lion]]'}.

Find namespace id

[सम्पादयतु]

mHatnote.findNamespaceId(link, removeColon)

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: mHatnote.findNamespaceId('Lion') → 0; mHatnote.findNamespaceId('Category:Lions') → 14; mHatnote.findNamespaceId(':Category:Lions') → 14; mHatnote.findNamespaceId(':Category:Lions', false) → 0 (the namespace is detected as ":Category", rather than "Category")

Make wikitext error

[सम्पादयतु]

mHatnote.makeWikitextError(msg, helpLink, addTrackingCategory)

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; however, if addTrackingCategory is not false after being passed through Module:Yesno, then the category is suppressed. This means that the category can be suppressed with addTrackingCategory values including "no", "n", 0, "false", and false.

Examples:

mHatnote.makeWikitextError('an error has occurred') → Error: an error has occurred.

mHatnote.makeWikitextError('an error has occurred', 'Template:Example#Errors') → Error: an error has occurred (help).
