New page

{{used in system}}
{{Module rating|beta}}
== Main function ==
The 'main' function of this module accepts the name of a single page. It determines if the page is a redirect; if so it looks up the page, extracts the target, and returns the target name as text. Its usage is <nowiki>{{#invoke:redirect|main|redirect-page-name}}</nowiki>.

The template normally neither takes nor gives square brackets, so to show the result as a link use <nowiki>[[{{#invoke:redirect|main|redirect-page-name}}]]</nowiki>. An error is produced if the redirect does not exist, but for versatility no error is given if the file is not a redirect (returns the original text) or if the file name is blank (returns blank).

However, if the parameter ''bracket'' is given a nonblank value, brackets will be passed on if present.

===Examples===
''See [[Module:Redirect/testcases]]''

<nowiki>{{#invoke:redirect|main|SW:AFC}}</nowiki>

produces

{{#invoke:redirect|main|SW:AFC}}

<nowiki>{{#invoke:redirect|main|[[SW:AFD]]|bracket=yes}}</nowiki>

produces

{{#invoke:redirect|main|[[SW:AFD]]|bracket=yes}}

If the target isnt a redirect:

<nowiki>{{#invoke:redirect|main|Stiles.casa Wiki:Articles for deletion|}}</nowiki>

produces

{{#invoke:redirect|main|Stiles.casa Wiki:Articles for deletion|}}

== Block function ==
The 'block' function replaces redirects with the actual names of articles in text entered either directly (using the ''text='' parameter) or by specifying the name of an index page in the first unlabelled parameter. Because checking for redirects is [[SW:expensive]], it only checks a limited number of links, so a feature is given to start only after reaching a link with a particular name. There is also a feature to limit replacements to piped links (<nowiki>[[A|B]]</nowiki> or unpiped links, or to make a piped link when an unpiped link is changed. This allows it to be used to make limited substitutions in articles without disrupting the text.

=== parameters ===
* ''1 ='' provides the name of the page containing the multiple redirects to process. Ignored if ''text'' is specified.
* ''text ='' (or unnamed first parameter) provides a text on which to do substitutions
* ''2 ='' (or unnamed second parameter) specifies the name of a wikilink (given in its original form, perhaps a redirect) at which to begin substitutions.
* ''pipe =''
:* If omitted, all links are processed: <nowiki>[[A]] -> [[X]], [[A|B]] -> [[X|B]]</nowiki>
:* If ''no'', unpiped links are processed: <nowiki>[[A]] -> [[X]], [[A|B]] -> [[A|B]]</nowiki>
:* If ''yes'', piped links are processed: <nowiki>[[A]] -> [[A]], [[A|B]] -> [[X|B]]</nowiki>
:* If ''make'', all links are processed, pipes are added on rename if absent: <nowiki>[[A]] -> [[A|X]], [[A|B]] -> [[X|B]]</nowiki>. Note that ''make'' is the setting most practical for article text to be subsequently screened for duplicate wikilinks.
* ''nowiki ='' (set to 'no' if some processing of the output is desired; usually you don't want this)
