Module:Hatnote

The pages listed in this category are templates.

This page is part of OODA WIKI's administration and not part of the encyclopedia.

Further template category notes

This category contains pages in the template namespace. It should not be used to categorize articles or pages in other namespaces.

To add a template to this category:

• If the template has a separate documentation page (usually called "Template:template name/doc"), add
•  [[Module:Hatnote]]
• to the <includeonly> section at the bottom of that page. Otherwise, add
•  <noinclude>[[Module:Hatnote]]</noinclude>
• to the end of the template code, making sure it starts on the same line as the code's last character.

This category is an index of templates which use TemplateStyles. It is automatically populated by {{Uses TemplateStyles}}.

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. 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 OODA WIKI (see Template:Selfref))

The CSS of the hatnote class is defined in Module:Hatnote/styles.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.

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') →

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

Examples
