This Lua module is used in system messages, and on approximately 18,200,000 pages, or roughly 74261% 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 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.)
