This module displays an icon depending on the code it is given. It implements Template:Icon.
 | This Lua module is used on approximately 381,000 pages. To avoid large-scale disruption and unnecessary server load, any changes to it should first be tested in the module's /sandboxor/testcases subpages. The tested changes can then be added to this page in a single edit. Please consider discussing 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, 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. |
From wikitext this module should be used via Template:Icon. Please see the template page for documentation.
To use this module from another Lua module, first load it:
Module documentationlocal mIcon = require('Module:Icon')
Then you can make icons with the _main function.
mIcon._main(args)
The args variable is a table of arguments. This corresponds to the parameters accepted by Template:Icon - please see the template page for parameter documentation.
The icon data is stored at Module:Icon/data. See the instructions there for how to add and remove icons.
| The above documentationistranscluded from Module:Icon/doc. (edit | history) Editors can experiment in this module's sandbox (create | mirror) and testcases (edit | run) pages. Subpages of this module. |
