Module:Portal-inline

This module is subject to page protection. It is a highly visible module in use by a very large number of pages, and/or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

This Lua module is used on approximately 210,000 pages.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

This module depends on the following other modules:

Module:Portal (sandbox)

This module implements Template:Portal-inline. This module accepts one unnamed parameter which is the portal to link to and several named parameters:

size— optional; Specify |size=tiny to show a 16×16 image instead of the usual size.
text— optional; Specify |text=(name) for a different associated name to appear.
short— optional; Specify |short=anything to remove portal from the output.
redlinks— optional; Specify |redlinks=yes to show the portal if it is redlinked.
