 | This is the module sandbox page for Module:Icon (diff). See also the companion subpage for test cases (run). |
 | 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. |
 | This Lua module is used on approximately 608,000 pages, or roughly 1% of all pages. To avoid major disruption and server load, any changes should be tested in the module's /sandboxor/testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
This module displays an icon depending on the code it is given. It implements Template:Icon.
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:
local 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.
