This page is not an actual Scribunto module. It exists to provide editors a place to create experimental modules.

Naming your modules

To keep things tidy, please use the following format to name your experimental modules:

Module:Sandbox/Your username/Module name

Cleaning up unused modules

Experimental modules may be deleted by admins upon request or after a long period of inactivity.

List of modules in this area

For a list of the experimental modules under Module:Sandbox, see Special:PrefixIndex/Module:Sandbox/.

local p = {}
local getArgs

function p.main(frame)

		getArgs = require('Module:Arguments').getArgs
	end
	local args = getArgs(frame)
	return p._main(args)
end
function p._main(n, d)
	return args.view
