Module:Anchor/sandbox
 | This is the module sandbox page for Module:Anchor (diff). See also the companion subpage for test cases (run). |
 | This Lua module is used in system messages, and on approximately 84,000 pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption, 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 rated as ready for general use. It has reached a mature state, is considered relatively stable and bug-free, and may be used wherever appropriate. It can be mentioned on help pages and other Wikipedia resources as an option for new users. To minimise server load and avoid disruptive output, improvements should be developed through sandbox testing rather than repeated trial-and-error editing. |
 | This module depends on the following other modules: |
This module implements {{anchor}}. Please see the Template:Anchor/doc page for documentation.
