Template:Citation/make link/doc

This is a documentation subpage for Template:Citation/make link.
It contains usage information, categories and other content that is not part of the original template page.

This template is used on 1,500,000+ pages.
To avoid large-scale disruption and unnecessary server load, any changes should first be tested in this template's /sandbox or /testcases subpage, or in your own user space.

This template is a "subroutine" of {{Citation/core}} used for conditionally making links for the chapter= and title= fields in a citation.

It is invoked as:

{{Citation/make link

| 1 = <value of IncludedWorkURL= or URL= or PMC= parameters>

| 2 = <value of IncludedWorkTitle= or Title= parameters>

}}

It uses the following algorithm:

If the first parameter is empty, it returns the second parameter as plain text.
If the first parameter is a URL, it returns the second parameter wrapped inside an external link to the first.

This "subroutine" is designed for {{Citation/core}} and makes assumptions that may not be valid elsewhere.

Examples:

"{{Citation/make link||BBC News front page}}" produces "BBC News front page".
"{{Citation/make link|http://news.bbc.co.uk/|BBC News front page}}" produces "BBC News front page".
