Template:Tl/sandbox

Correct

One anonymous parameter matching a template name

Wiki code

{{Tl|RootCmd}}

Main version

{{RootCmd}}

Sandbox version

{{RootCmd}}

Using {{!}} (producing a piped link) and <nowiki> to illustrate a template call with a parameter

Wiki code

{{Tl|RootCmd{{!}}<nowiki>{{RootCmd|umount /mnt/gentoo}}</nowiki>}}

Main version

{{RootCmd|umount /mnt/gentoo}}

Sandbox version

{{RootCmd|umount /mnt/gentoo}}

↑ This is somewhat awkward, so you might want to avoid using this template to illustrate template calls containing parameters until it "natively supports" such use cases. In the meantime, the above link can be generated using [[Template:RootCmd|<nowiki>{{RootCmd|umount /mnt/gentoo}}</nowiki>]].

Incorrect

No parameter (error message)

Wiki code

{{Tl}}

Main version

{{Tl template error}}

Parameter unnamed not defined. For correct usage see Tl template's documentation on the unnamed parameter.

Sandbox version

{{Tl template error}}

Parameter unnamed not defined. For correct usage see Tl template's documentation on the unnamed parameter.

Two anonymous parameters to illustrate a template call containing a parameter (not supported)

Wiki code

{{Tl|RootCmd|umount /mnt/gentoo}}

Main version

{{RootCmd}}

Sandbox version

{{RootCmd}}

Two anonymous parameters to illustrate a template call containing multiple parameters (not supported)

Wiki code

{{Tl|RootCmd|umount /mnt/gentoo{{!}}output{{=}}umount: /mnt/gentoo: not mounted}}

Main version

{{RootCmd}}

Sandbox version

{{RootCmd}}

↑ Note that everything from "umount" to "not mounted" is a single anonymous parameter.

Three or more anonymous parameters (will probably never be supported)

Wiki code

{{Tl|RootCmd|umount /mnt/gentoo|output{{=}}umount: /mnt/gentoo: not mounted}}

Main version

{{RootCmd}}

Sandbox version

{{RootCmd}}

One anonymous parameter containing {{!}} to display a pipe character (makes a piped link instead)

Wiki code

{{Tl|RootCmd{{!}}umount /mnt/gentoo}}

Main version

umount /mnt/gentoo

Sandbox version

umount /mnt/gentoo

↑ Remember that the first anonymous parameter is assumed to be a template name that can be linked to.
