Data mapping

For code-to-name mapping, this module uses data from:

Module:ISO 639 name/ISO 639-1 – from IANA language-subtag-registry file; this data used only for ISO 639-1 language codes / names listed there
Module:ISO 639 name/ISO 639-2 – from Codes for the Representation of Names of Languages
Module:ISO 639 name/ISO 639-2B – from Codes for the Representation of Names of Languages
Module:ISO 639 name/ISO 639-3 – from sil.org UTF-8 Complete Code Tables Set
Module:ISO 639 name/ISO 639-5 – from Codes for the Representation of Names of Languages Part 5
Module:ISO 639 name/ISO 639 deprecated – from ISO 639-2/RA Change Notice and ISO 639-5 Change Notice includes:
- Module:ISO 639 name/ISO 639-3 (dep) – from sil.org UTF-8 Complete Code Tables Set (Retirements)
Module:ISO 639 name/ISO 639 override – code to name mapping where the name is different from the name in the ISO 639 standard

For name-to-code mapping, this module uses data from:

Module:ISO 639 name/ISO 639 name to code – names and codes extracted from the code-to-name data set above

iso_639_name_exists

Returns true when <language name> is found in one of the ISO 639-1, -2, -3, -5, or override tables; returns nil else.

Useage:

{{#invoke:ISO 639 name|iso_639_name_exists|<language name>}}

Examples:

without required <language name>:

{{#invoke:ISO 639 name|iso_639_name_exists}} →

with valid <language name>:

with invalid <language name>:

iso_639_name_to_code

Returns ISO 639 language code associated with <language name>. May return an error message with or without a language name.

This function may not be particularly useful because, except for case, <language name> must exactly match the name in the data tables.

Optional parameters:

<part> (second positional parameter) – limits return to codes from the specified <part> (1, 2, 3, 5), override table first then the appropriate data table; when not supplied, this function searches in order part 1 to part 5. The search stops when a match is found.

|hide-err=yes: suppresses error messages

Examples:

without <part>, with ISO 639-5 name:

{{#invoke:ISO 639 name|iso_639_name_to_code|North Germanic languages}} → gmq

with <part>:

{{#invoke:ISO 639 name|iso_639_name_to_code|Navajo|2}} → nav

iso_639

When given an ISO 639 language code, return the associated language name; when given a language name, returns the associated ISO 639 language code. May return an error message with or without a language code/name.

This function may not be particularly useful because, except for case, a provided <language name> must exactly match the name in the data tables.

Optional parameters:

<part> (second positional parameter) – limits return to codes/names from the specified <part> (1, 2, 3, 5), override table first then the appropriate data table; when not supplied, this function searches in order part 1 to part 5. The search stops when a match is found.

|hide-err=yes: suppresses error messages

Examples:

without <part>, with ISO 639-5 code:

{{#invoke:ISO 639 name|iso_639|gmq}} → North Germanic languages

without <part>, with ISO 639-5 name:

{{#invoke:ISO 639 name|iso_639|North Germanic languages}} → gmq

with <part> and <code>:

{{#invoke:ISO 639 name|iso_639|nav|2}} → Navajo

with <part> and <name>:

{{#invoke:ISO 639 name|iso_639|Navaho|2}} → nav
