Editing Module:Redirect/sandbox/doc (section)

== 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|WP:AFC}}</nowiki>

produces

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

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

produces

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

If the target isnt a redirect:

<nowiki>{{#invoke:redirect|main|Wikipedia:Articles for deletion|}}</nowiki>

produces

{{#invoke:redirect|main|Wikipedia:Articles for deletion|}}
