Module:Lua banner

This module implements the {{Lua}} template.

Usage from wikitext

This module cannot be used directly from wikitext, but only through the {{Lua}} template. Please see the template page for documentation.

Usage from Lua modules

To use this module from other Lua modules, first load the module:

local mLuaBanner = require('Module:Lua banner')

You can then generate a side box using the _main function:

mLuaBanner._main(args)

The args variable should be a table containing the arguments to pass to the module. To see the different arguments that can be specified and how they affect the module output, please refer to the {{Lua}} template documentation.

Tracking category

• Category:Lua templates with errors (0)
