Module:Navbar

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

This module depends on the following other modules: Module: Ordinal Module: Yesno

This module is used to store functions for templates that generate a navigation bar:

• Template:Navbox Lumatone
• Template:Navbox fractional-octave

Template:Navbar also uses this module, even though it only generates View/Talk/Edit links.

To include this module in other modules, use local navbar = require("Module:Navbar")._navbar.

• Module:Navbox
