Module:If empty
From The Sextant of Worlds
| Ready for use | This module is rated as ready for general use. It has reached a mature form and is thought to be relatively 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. |
| Protected | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, 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. |
| File:Cascade-protection-shackle.svg | This module can only be edited by administrators because it is transcluded onto one or more cascade-protected pages. |
| File:Lua-Logo.svg | This module depends on the following other modules: |
| Warning | This Lua module is used in system messages, and on approximately 4,030,000 pages, or roughly 511421% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. 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. Please discuss changes on the talk page before implementing them. |
This module supports Template:If empty. See here for test cases.
