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}}→Example hatnote text
Errors
If no hatnote text is supplied, the template will output the following message:
- {{{text}}}
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.
