View source for Template:Is redirect/doc

{{Documentation subpage}}
{{High-use}}
{{Lua|Module:Pagetype}}
Returns <code>yes</code> when {{para|1|''somepagename''}} is a redirect, and a &lt;blank space> when ''not'' a redirect.

For illustration purposes, in this documentation redirect pages are in italics: ''[[Mainpage]]'' &rarr; [[Main_Page]]

:Expect 'yes': <code><nowiki>{{Is redirect|Autism spectrum}}</nowiki></code> &rarr; {{Is redirect|Autism spectrum}}
:Expect '&lt;blank>' (no): <code><nowiki>{{Is redirect|Autism}}</nowiki></code> &rarr; {{Is redirect|Autism}}

==Talkpage handling==
By default, a check specifying a talk page is performed on the corresponding ''subject page'' (it's associated page in mainspace, or in Template space, etc.).
;To check the talkpage itself, both use {{para|talk|yes}} and the talk page name.
:<code><nowiki>{{Is redirect|Talk:Autism spectrum|talk=yes}}</nowiki></code> &rarr; {{Is redirect|1=Talk:Autism spectrum|talk=yes}}

Background. By default, when entering a {{mono|Talkpage}} to check (like {{code|1=Talk:Autism spectrum}}), ''the check is performed on the subject page''. This stems from the [[:Module:Pagetype|module used]]. For example:
:Page to check: {{code|Talk:Autism spectrum}}: <code><nowiki>{{Is redirect|Talk:Autism spectrum}}</nowiki></code>
:Current pages status: ''{{no redirect|Autism spectrum}}'' is a ''redirect'', {{no redirect|1=Talk:Autism spectrum}} is {{strong|not}} a redirect (it has content).
:{{tlx|Is redirect}} returns:
::<code><nowiki>{{Is redirect|Autism spectrum}}</nowiki></code> &rarr; {{Is redirect|1=Autism spectrum}} {{aye}}
::<code><nowiki>{{Is redirect|Talk:Autism spectrum}}</nowiki></code> &rarr; {{Is redirect|1=Talk:Autism spectrum}} {{Question mark}} ''(unexpected for the talkpage itself)''
::Applying {{code|Talk:Autism}}:
::<code><nowiki>{{Is redirect|Talk:Autism spectrum|talk=yes}}</nowiki></code> &rarr; {{Is redirect|1=Talk:Autism spectrum|talk=yes}} {{aye}}
::Applying the subject page {{code|Autism}}:
::<code><nowiki>{{Is redirect|Autism spectrum|talk=yes}}</nowiki></code> &rarr; {{Is redirect|1=Autism spectrum|talk=yes}} {{aye}} ''({{para|talk|yes}} for a subject page name checks the subject page, not the associated talk page)''

== Usage ==

* {{no redirect|Main_Page}} (expect neg): <code><nowiki>{{is redirect|Main_Page}}</nowiki></code> &rarr; {{is redirect|Main_Page}}
* ''{{no redirect|Mainpage}}'' (expect yes): <code><nowiki>{{is redirect|Mainpage}}</nowiki></code> &rarr; {{is redirect|Mainpage}}

Can be used as:
:<code><nowiki>{{#if:{{Is redirect|somepagename}} |value when yes |value when no}}</nowiki></code>
