Template:Template parameter usage

See the monthly error report for this template.

Template documentation[view] [edit] [history] [purge]

The Template Parameters tool is available for viewing template parameter usage in articles. It works with TemplateData to show the frequency of parameter name usage in a template's mainspace transclusions, along with whether or not each parameter is listed in that template's TemplateData code as a supported parameter. For a required parameter, it can display a list of pages where the template is missing that parameter. The tool also shows commonly used values for each parameter. Each report is updated monthly and does not reflect changes made to articles or to the TemplateData code after the report's generation.

Usage

Example:

• {{Infobox lighthouse}}/documentation: Template:Infobox lighthouse § TemplateData → "Click here to see a monthly parameter usage report ..." → [1].

Parameters

{{Template parameter usage
| 1 = <!-- template:name, default=pagename -->
| lc = <!-- yes/no -->
| label = <!-- keywords like "for", or free labeltext -->
}}

All parameters are optional, and have a default

By default, the template links for the template page:

{{Template parameter usage}} → See the monthly error report for this template. [for this page]

One can enter a template name:

{{Template parameter usage|Infobox film}} → See the monthly error report for this template.

Optional:

• |lc=yes for lowercase "click": See the monthly error report for this template.
• Entering |1=Template:Infobox film is accepted (namespace is removed). Editor friendly, using a positional parameter.

When |1= is used, "this template" text changes: → See the monthly error report for this template.

• |label= sets the visible text; it does not change the target link:

|label= default → See the monthly error report for this template.

|label=none → See the monthly error report for this template.

|label=for → See the monthly error report for this template.

|label=FooBar → See the monthly error report for this template.

• |based=yes adds the text "based on this TemplateData" to the end of the template (or "based on its TemplateData" if |1= is also used).

The template is included in transclusions of {{TemplateData header}}.

Error reports

By default, it links a report for the template-page being viewed. To link a report for a different template-page, pass it as the first parameter:

{{Template parameter usage|Example}} makes a link to the error report for Template:Example:

→ See the monthly error report for this template.

The first character can be made lowercase to follow on at the end of a sentence:

Blah, {{Template parameter usage|lc=yes}} → Blah, See the monthly error report for this template.
