Module:Navbox

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

This module implements a metatemplate, and may be invoked by templates using its corresponding template Template:Navbox, or used directly from other modules.

Module:Navbox is a module that implements the {{Navbox}} template. Navbox templates can be made by using the template or by calling the _navbox function from another module.

On templates, you can create a navbox by using {{Navbox}}, which calls this module's wrapper function.

On modules, you can include local navbox = require("Module:Navbox")._navbox to create a navbox.

-- TODO: add an option for a dataless header row, to mirror the option of having
-- a headerless data row. Requires a change to how rows are processed: instead
-- of a table that is a one-element array (for headerless rows) or two-element
-- array (for header+data rows), it's an associative array containing entries
-- for both; the absence of one (as nil) differentiates between headerless rows
-- and dataless rows.

-- Navbox row helper function
-- Function was refactored to use table.concat(), like with the "main" function,
-- since it's being called multiple times. The other helper functions don't need
-- to be refactored (currently) because they only need to be called a fixed
-- number of times.
