Template:Hatnote/doc

Template page

Description and use[edit source]

This template produces a hatnote:

It is placed at the top of the article or section that is the primary topic of a redirect, and links to other topics that are ambiguous with the name of that redirect. This template is used instead of the generic {{for}} in order to reduce reader confusion.

An example would be when a user searches for the emperor Achilleus. However, the search term "Achilleus" redirects to the page titled Achilles (as in the mythical hero) because it is considered more likely the user were searching for the very well known hero than a relatively obscure emperor. Now, at the top of this Achilles page you will (among other things) find the following hatnote:

"Achilleus" redirects here. For the Roman emperor with this name, see Achilleus (Roman usurper).

That text is this template in action.

Parameters[edit source]

Template:Expand-section A |text= option adds text to the end; note that this should only be used when truly necessary, when the other hatnote templates listed below don't suffice.

Template:Hatnote templates


Template:Never substitute

This template produces formatted text, following the guideline for a Wikipedia hatnote:

{{Hatnote|Example hatnote text.}}

Broadly speaking, a hatnote should answer a reader's question (maybe preemptively): Am I on the right page?

Template:TOC limit

Function[edit source]

This template is primarily used to add a correctly formatted hatnote to a page. Often, but not always, this is a disambiguation link at the top of article pages. It places an HTML div- / div block around the text entered as its only argument, which provides standardized formatting (contents are indented and italicized in most displays); it also isolates the contained code to make sure that it is interpreted correctly.

This template is also used as the "meta-template" for additional specialized disambiguation link templates; see Category:Hatnote templates for a list.

The template does not automatically create links of any kind. Links and other desired formatting must be explicitly added, using normal Wikipedia markup.

Usage[edit source]

Basic usage
{{hatnote|text}}
All parameters
{{hatnote|text|extraclasses=extra classes|selfref=yes|category=no}}

Parameters[edit source]

This template accepts the following parameters:

  • 1 – the hatnote text (required)
  • extraclasses – any extra CSS classes to be added, for example, the {{see also}} template adds the classes "|extraclasses=boilerplate seealso".
  • selfref – If set to "yes", "y", "true" or "1", adds the CSS class "selfref". This is used to denote self-references to Wikipedia. See Template:Selfref for more information.
  • category – If set to "no", "n", "false", or "0", suppresses the error tracking category (Category:Hatnote templates with errors). This has an effect only if the leftmost parameter (the hatnote text) is omitted.

Example[edit source]

  • {{hatnote|Example hatnote text}}

Errors[edit source]

If no hatnote text is supplied, the template will output the following message:

  • Error: no text specified (help).

If you see this error message, it is for one of four reasons:

  1. No parameters were specified (the template code was {{hatnote}}). Please use {{hatnote|text}} instead.
  2. Some parameters were specified, but the hatnote text wasn't included. For example, the template text {{hatnote|extraclasses=seealso}} will produce this error. Please use (for example) {{hatnote|text|extraclasses=seealso}} instead.
  3. The hatnote text was specified, but that text contains an equals sign ("="). The equals sign has a special meaning in template code, and because of this it cannot be used in template parameters that do not specify a parameter name. For example, the template code {{hatnote|2+2=4}} will produce this error. To work around this, you can specify the parameter name explicitly by using 1= before the hatnote text, like this: {{hatnote|1=2+2=4}}.
  4. You tried to access Module:Hatnote directly by using {{#invoke:hatnote|hatnote|text}}. Use of #invoke in this way has been disabled for performance reasons. Please use {{hatnote|text}} instead.

If you see this error message and are unsure of what to do, please post a message on Template talk:Hatnote, and someone should be able to help you.

Pages that contain this error message are tracked in Category:Hatnote templates with errors.

Technical details[edit source]

The HTML code produced by this template looks like this:

  • <div role="note" class="hatnote navigation-not-searchable">hatnote text</div>

The code is produced by Module:Hatnote.
