Module:Subject bar
Appearance
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 implements the {{Subject bar}} template. Please don't use this module from an article or from another wiki page. You should use the {{Subject bar}} template instead. To use the module from another Lua module, read on.
For test cases, see {{Subject bar/testcases}}.
Use from another Lua module
[සංස්කරණය]Load the module like this:
local subjectBar = require('Module:Subject bar')._main
Then you can use the subjectBar
function like this:
local myBar = subjectBar{
portal = 'Portal 1',
portal2 = 'Portal 2',
-- ...
commons = true,
commons-search = 'Commons search string',
wikt = true,
wikt-search = 'Wiktionary search string'
-- ...
}
Please see Template:Subject bar/doc for a full list of possible parameters.
