模組:Lang/doc

This module exists primarily to provide correct html markup for non-English language text where that text is used in the English Wikipedia. It has a secondary purpose of providing correct visual rendering for this non-English text. The module consolidates processing for {{lang}} and the many {{lang-??}} templates into a single source and uses a clearly defined data set extracted from international standards.

The data set is specified in Module:Language/name/data and its included data modules:

language code-and-name data

Module:Language/data/iana languages – from IANA language-subtag-registry file

Module:Language/data/ISO 639-3 – from sil.org UTF-8 Complete Code Tables Set

Module:Language/data/wp languages – sourcing for the data in this module is unknown

language script data

Module:Language/data/iana scripts – from IANA language-subtag-registry file

language region data

Module:Language/data/iana regions – from IANA language-subtag-registry file

language variant data

Module:Language/data/iana variants – from IANA language-subtag-registry file

suppressed-script data

Module:Language/data/iana suppressed scripts – from IANA language-subtag-registry file

The data set also includes supplementary data modules:

override and other non-standard data

Module:Lang/data – For example, when IANA disagrees with ISO 639-3 or when the standard language name is cumbersome or contains information not suitable for use in article space, the override table can hold that language information

Module:Lang/ISO 639 synonyms – maps three character ISO 639-2, -2T, -3 codes to two character ISO 639-1 codes – from Codes for the Representation of Names of Languages

The module does not require the myriad {{ISO 639 name ??}} templates, {{Language with name}}, {{Language with name and transliteration}}, and {{transl}}. It provides error checking and reporting to ensure that the html rendered is correct for browsers and screen readers.

Articles that have errors are placed in:

Category:lang and lang-xx template errors (mainspace only)

Maintenance categories:

Category:Lang and lang-xx code promoted to ISO 639-1
