Module:Hatnote/doc

This is a meta-module that provides various functions for making hatnotes. It implements the {{hatnote}} template, for use in disambiguation hatnotes at the top of pages, and the {{rellink}} template, for use in making links to related articles directly under section headings. It also implements the {{format hatnote link}} template, which is used to format a wikilink for use in hatnotes.

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, Template:Rellink and Template:Format hatnote link for documentation.

Use from other Lua modules

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

mHatnote._hatnote(s)

Formats the string s as a hatnote. This encloses s in the tags <div class="dablink">...</div>. The CSS of the dablink class is defined in MediaWiki:Common.css.

Example

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

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

Displays as:

This is a hatnote.

Rellink

mHatnote._rellink(s, extraclasses)

Formats the string s as a "related articles" link. This encloses s in the tags <div class="rellink">...</div>. The CSS of the dablink class is defined in MediaWiki:Common.css. Extra classes can be added as the string extraclasses.

Example 1

mHatnote._rellink('This is a related article link.')

Produces: <div class="rellink">This is a related article link.</div>

Displays as:

This is a related article link.

Example 2

mHatnote._rellink('This is a related article link.', 'boilerplate seealso')

Produces: <div class="rellink boilerplate seealso">This is a related article link.</div>

Displayed as:

This is a related article link.

Format link

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

Find namespace id

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")

Format pages

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

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]]'}.
