Module:Lua banner

Module documentation[view] [edit] [history] [purge]

This module implements the {{Lua}} template.

Usage

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

From other 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 above 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.
