Template:When in sandbox
Template documentation{{When in sandbox (|return this, otherwise) return "/sandbox" (|else return this)}}
Returns "/sandbox" – or, if supplied, the first unnamed parameter ("return this" above) – 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 – or, if supplied, the second unnamed parameter ("else return this" above). It corresponds to {{When pagename is |/sandbox={{{return this|/sandbox}}} |other={{{else return this|}}}}}.
This can be useful to e.g. switch the version of a template used in its /doc[umentation] to the version in its sandbox (by replacing <templatestyles src="Mono/styles.css" />{{template_name ... on the /doc page with <templatestyles src="Mono/styles.css" />{{template_name{{\sandbox}} ...) when that documentation is transcluded on the template's sandbox page.
| The above documentation is transcluded from Template:When in sandbox/doc. (edit | history) Editors can experiment in this template's sandbox (create | mirror) and testcases (create) pages. Please add categories to the /doc subpage. Subpages of this template. |
