Module:ISO 639 name/doc

This module is used by {{ISO 639 name}}.

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

Module:Language/data/ISO 639 override – code to name mapping where the name is different from the name in the ISO 639 standard

Module:Language/data/iana languages – from IANA language-subtag-registry file; this data used only for ISO 639-1 language codes / names listed there

Module:Language/data/ISO 639-2 – from Codes for the Representation of Names of Languages

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

Module:Language/data/ISO 639-5 – from Codes for the Representation of Names of Languages Part 5

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

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

Errors are tracked in:

Category:ISO 639 name template errors (27)

iso_639_code_exists

Returns true when <code> 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_code_exists|<code>}}

Examples:

without required <code>:

{{#invoke:ISO 639 name|iso_639_code_exists}} →

with valid <code>:

{{#invoke:ISO 639 name|iso_639_code_exists|nav}} → true

with invalid <code>:

{{#invoke:ISO 639 name|iso_639_code_exists|xx}} →

iso_639_code_to_name

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

Optional parameters:

|hide-err=yes: suppresses error messages

|link=yes: creates link to en.wiki article about the language

|label=<label text> – requires |link=yes; label for the language-name link: [[<language name> language|<label text>]]

Examples:

without required <code>:

{{#invoke:ISO 639 name|iso_639_code_to_name}} →

with valid <code>:

{{#invoke:ISO 639 name|iso_639_code_to_name|nav}} → Navajo

with invalid <code>:

{{#invoke:ISO 639 name|iso_639_code_to_name|xx}} →

with invalid <code> (IETF language tag):

{{#invoke:ISO 639 name|iso_639_code_to_name|nv-Latn}} → Navajo

with invalid <code>, error message suppressed:

{{#invoke:ISO 639 name|iso_639_code_to_name|nv-Latn|hide-err=yes}} → Navajo

{{#invoke:ISO 639 name|iso_639_code_to_name|nav|link=yes}} → Navajo

linked with alternate spelling:

{{#invoke:ISO 639 name|iso_639_code_to_name|nav|link=yes|label=Navaho}} → Navaho

iso_639_code_1_to_name

Same as iso_639_code_to_name except that <code> must be an ISO 639-1 code; search is constrained to Module:Language/data/ISO 639 override and Module:Language/data/iana languages.

Example:

with valid <code>:

{{#invoke:ISO 639 name|iso_639_code_1_to_name|nv}} → Navajo

with invalid <code>:

{{#invoke:ISO 639 name|iso_639_code_1_to_name|xx}} →

iso_639_code_2_to_name

Same as iso_639_code_to_name except that <code> must be an ISO 639-2 code; search is constrained to Module:Language/data/ISO 639 override and Module:Language/data/ISO 639-2.

Example:

with valid <code>:

{{#invoke:ISO 639 name|iso_639_code_2_to_name|apa}} → Apache languages

with invalid <code>:

{{#invoke:ISO 639 name|iso_639_code_2_to_name|xxx}} →

iso_639_code_3_to_name

Same as iso_639_code_to_name except that <code> must be an ISO 639-3 code; search is constrained to Module:Language/data/ISO 639 override and Module:Language/data/ISO 639-3.

Example:

with valid <code>:

{{#invoke:ISO 639 name|iso_639_code_3_to_name|nav}} → Navaho

with invalid <code>:

{{#invoke:ISO 639 name|iso_639_code_3_to_name|xxx}} →

iso_639_code_5_to_name

Same as iso_639_code_to_name except that <code> must be an ISO 639-5 code; search is constrained to Module:Language/data/ISO 639 override and Module:Language/data/ISO 639-5.

Example:

with valid <code>:

{{#invoke:ISO 639 name|iso_639_code_5_to_name|apa}} → Apache languages

with invalid <code>:

{{#invoke:ISO 639 name|iso_639_code_5_to_name|xxx}} →

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
