Module:Template link general
Appearance
This module is rated as ready for general use. It has reached a mature form and is thought to be bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
Implements {{Template link general}} and other templates in its family.
Basic usage
{{#invoke:Template link general|main}}
This module is used by {{Template link general}} and related templates to display links to templates. It is similar to {{Template link}} but with additional formatting options and the ability to include parameters in the display. See Template:Template link general § Parameters for the full list, which can be enabled by passing any value to them (such as "on", "yes", etc).
