|This Lua module is used in system messages, and on approximately 18,400,000 pages, or roughly 33% 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 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 module causes an error if any nil global is read or if any global is written to, with the exception of arg. To use, add
require('Module:No globals') to the top of the module using it. The arg variable is excluded because it is necessary for Scribunto's require function to work properly. (See the Scribunto source code here.)
- Module:Log globals – adds all nil global reads/writes to the Lua log
