Error: {{Module rating}} must be placed in the Module namespace.

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.

local mHatnote = require('Module:Hatnote')

You can then use the functions as documented below.

Hatnote

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:

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:

Format link

mHatnote._formatLink{link = link, display = display, italicizePage = true, italicizeSection = true}

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 italicizePage is true then the section portion of the link is italicized.

Examples
mHatnote._formatLink{link = 'Lion'} → [[Lion]] → Lion
mHatnote._formatLink{link = 'Lion#Etymology'} → [[Lion#Etymology|Lion §&nbsp;Etymology]] → Lion § Etymology
mHatnote._formatLink{link = 'Category:Lions'} → [[:Category:Lions]] → Category:Lions
mHatnote._formatLink{link = 'Lion#Etymology', display = 'Etymology of lion'} → [[Lion#Etymology|Etymology of lion]] → Etymology of lion
mHatnote._formatLink{link = 'Quo warranto#Philippines', italicizePage = true} → [[Quo warranto#Philippines|<i>Quo warranto</i> §&nbsp;Philippines]] → Quo warranto § Philippines
mHatnote._formatLink{link = 'Cybercrime Prevention Act of 2012#Disini v. Secretary of Justice', italicizeSection = true} → [[Cybercrime Prevention Act of 2012#Disini v. Secretary of Justice|Cybercrime Prevention Act of 2012 §&nbsp;<i>Disini v. Secretary of Justice</i>]] → Cybercrime Prevention Act of 2012 § Disini v. Secretary of Justice

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]]'}.

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")

Make wikitext error

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 (0). To suppress categorization, pass false as third parameter of the function (addTrackingCategory).

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).

Examples

For an example of how this module is used in other Lua modules, see Module:Main
