Template:Is redirect/doc

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

This template is used on approximately 28,000 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua: Module:Pagetype (sandbox)

Returns yes when |1=somepagename is a redirect, and a <blank space> when not a redirect.

For illustration purposes, in this documentation redirect pages are in italics:

Background. By default, when entering a Talkpage to check (like Talk:Autism), the check is performed on the subject page. This stems from the module used. For example:

Page to check: Talk:Autism: {{Is redirect|Talk:Autism}}

Current pages status: Autism is a redirect, Talk:Autism is not a redirect (it has content).

{{Is redirect}} returns:

{{Is redirect|Autism}} → yes Y

{{Is redirect|Talk:Autism}} → yes ? (unexpected for the talkpage itself)

Applying Talk:Autism:

{{Is redirect|Talk:Autism|talk=yes}} → Y

Applying the súbject page Autism:

{{Is redirect|Autism|talk=yes}} → yes Y (|talk=yes for a súbject page name checks the subject page, not the associated talk page)

Usage

• Main Page (expect neg): {{is redirect|Main_Page}} →
• Mainpage (expect yes): {{is redirect|Mainpage}} → yes

Can be used as:

{{#if:{{Is redirect|somepagename}} |value when yes |value when no}}
