Template:Ifnoteq then show/doc

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

This template tests whether the first unnamed parameter is equal to the second unnamed parameter and returns the third unnamed parameter if it does. Otherwise it returns the first unnamed parameter.

This is useful when the first parameter is a {{#invoke: }} of a Lua module that returns a value for which a specific exception is required. Because it uses the {{#invoke: }} just once, it simplifies the coding of infoboxes, for example.

Usage

An infobox field may return the country (P17) for an article about a city. We may wish to use the abbreviation "USA" in place of "United States".
