This is a documentation subpage for Template:Terminate sentence
It may contain usage information, categories and other content that is not part of the original template page.

This template is used on approximately 10,100,000 pages, or roughly 3694% of all pages.
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. Consider discussing changes on the talk page before implementing them.

Usage

This {{WPBannerMeta}} subtemplate decides what kind of page and mode of use the template is being on. It performs two checks:

Is the page name the |BANNER_NAME=, or is the page a subpage of that page?
Is |category=yes, |category= (blank), |category=¬ or |category=banana (anything not explicity negative)?

And then combines them together either with logical operator "and" (default) or another logical operator, e.g. "or"; this can be specified in the first unnamed parameter.

Logical operator: and (default behaviour)

This is used by the main template and some hooks. It will return "yes" only if it is on the template page and is not being used as an example (e.g. on its documentation page). In this case the banner will appear in its 'demo' version with all options demonstrated.

Logical operation "and" (default)
		Yes
		Is the current page BANNER_NAME or a subpage?
Is category blank or anything apart from "no"?	Yes	yes
Is category blank or anything apart from "no"?	No

Logical operator: and not

This is used by some hooks. It will return "yes" only if it is not on the template page and is not being used as an example. This is suitable for non-visual output such as categories.

Logical operation "and not"
		Yes	No
		Is the current page BANNER_NAME or a subpage?
Is category blank or anything apart from "no"?	Yes		yes
Is category blank or anything apart from "no"?	No
