Usage 2
Example

This metamodule helps with loading of another module. That module is loaded only after one of its functions is called for the first time. This prevents it from being recorded as used on a given page if none of its functions is actually called.

Usage 1

local Loader = require('Module:Loader') -- Prefix 'Module:' is mandatory

local MyModule = Loader.load('Module:MyModule') -- Prefix 'Module:' is optional

Example

local Loader = require('Module:Loader')

local Math = Loader.load('Math')

return Math._random(10)

In this case Math is loaded when Math._random is accessed for the first time.

Usage 2

local load = require('Module:Loader').load -- Prefix 'Module:' is mandatory

local myFunction = load('Module:MyModule', 'myFunction') -- Prefix 'Module:' is optional

Example

local load = require('Module:Loader').load

local random = load('Math', '_random')

return random(10)

In this case Math is loaded when random(10) is called for the first time.
