Template:\sandbox/doc
 | This is a documentation subpage for Template:\sandbox. It may contain usage information, categories and other content that is not part of the original template page. |
 | This page is not a sandbox. It should not be used for test editing. To experiment, please use the Wikipedia sandbox or your user sandbox. |
Usage
changeReturns "/sandbox" if the template detects that the page where it is transcluded is a subpage named "sandbox" (i.e. a sandbox page); otherwise it returns nothing.
This can be useful to e.g. switch the version of a template used in its documentation to the version in its sandbox (by replacing {{template name}} on the /doc page with {{template name{{\sandbox}}}}) when that documentation is transcluded on the template's sandbox page.
