This module is used to retrieve and manage Wiktionary's various writing systems and the information associated with them. See Wiktionary:Scripts for more information.

The information itself is stored in Module:scripts/data. The data module should not be used directly by any other module, the data should only be accessed through the functions provided by Module:scripts.

For functions that allow templates to use this module, see Module:scripts/templates.

Finding and retrieving scripts

The module exports a number of functions that are used to find scripts.

export.makeObject

function export.makeObject(code, data)

This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.

export.getByCode

function export.getByCode(code, paramForError, disallowNil)

This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.

export.getByCanonicalName

function export.getByCanonicalName(name)

Script objects

A Script object is returned from one of the functions above. It is a Lua representation of a script and the data associated with it. It has a number of methods that can be called on it, using the : syntax. For example:

local m_scripts = require("Module:scripts")
local sc = m_scripts.getByCode("Latn")
local name = sc:getCanonicalName()
-- "name" will now be "Latin"
