Template:Hatnote/doc
 | This is a documentation subpage for Template:Hatnote. It contains usage information, categories, and other content that is not part of the original template page. |
 | This template is used in system messages, and on approximately 660,000 pages, or roughly 10681% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |
 | This template should not be substituted. |
__EXPECTUNUSEDTEMPLATE__
 | This template uses Lua: |
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?
Function
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
- Basic usage
- {{hatnote
|text}}
- All parameters
- {{hatnote
|text |extraclasses=extra classes |selfref=yes |category=no}}
Parameters
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
- {{hatnote
|Example hatnote text}} →
Errors
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:
- No parameters were specified (the template code was
{{hatnote}}). Please use{{hatnote|text}}instead. - 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. - 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 using1=before the hatnote text, like this:{{hatnote|1=2+2=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.
