Module:Icon/sandbox
 | This is the module sandbox page for Module:Icon (diff). See also the companion subpage for test cases (run). |
 | This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
 | 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 642,000 pages, or roughly 1% of all pages. 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. 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.
Usage
From wikitext
From wikitext this module should be used via Template:Icon in most cases. Please see the template page for documentation. In cases where lots of icons cause the page to exceed the post-expand include size limit, {{#invoke:Icon||icon name}} may be used instead of {{Icon|icon name}}.
From Lua
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.
Data
The icon data is stored at Module:Icon/data. See the instructions there for how to add and remove icons.
