Perl modules for working with language codes, language groups and language scripts. Currently, there are 3 modules in this package:
- ISO::639::3 - conversion between ISO language codes
- ISO::639::5 - language groups and families according to ISO 639-5
- ISO::15924 - language scripts and their connection to languages
A Perl modulino for retrieving and converting language codes from ISO 639.
The module provides simple functions for retrieving language names and codes from the ISO-639 standards. The main purpose is to convert between different variants of codes and to get the English names of languages from codes. The module contains basic functions. There is no object-oriented interface. All functions can be exported.
use ISO::639::3 qw/:all/;
print convert_iso639( 'iso639-1', 'fra' );
print convert_iso639( 'iso639-3', 'de' );
print convert_iso639( 'name', 'fa' );
print get_iso639_1( 'deu' );
print get_iso639_3( 'de' );
print get_language_name( 'de' );
print get_language_name( 'eng' );
print get_macro_language( 'yue' );
The module can be run as a script:
perl ISO/639_3.pm [OPTIONS] LANGCODE*
This converts all language codes given as LANGCODE to corresponding language names. OPTIONS can be set to convert
between different variants of language codes or to convert from language names to codes. The same functionality is also available via the script iso639 that is provided as executable in this package.
OPTIONS:
-2: convert to two-letter code (ISO 639-1)
-3: convert to three-letter code (ISO 639-3)
-m: convert to three-letter code but return the macro-language if available (ISO 639-3)
-n: don't print a final new line
$converted = convert_iso639( $type, $id ):
Convert the language code or language name given in $id. The $type specifies the output type that is generated. Possible types are "iso639-1" (two-letter code), "iso639-3" (three-letter-code), "macro" (three-letter code of the corresponding macro language) or "name" (language name). Default is to return the language name. Regional codes are stripped from the input language ID.
$iso639_1 = get_iso639_1( $id )
Return the ISO 639-1 code for a given language or three-letter code. Returns the same code if it is a ISO 639-1 code or 'xx' if it is not recognized.
$iso639_3 = get_iso639_3( $id )
Return the ISO 639-3 code for a given language or any ISO 639 code. Returns 'xxx' if the code is not recognized.
$macro_language = get_macro_language( $id )
Return the ISO 639-3 code of the macro language for a given language or any ISO 639 code. Returns 'xxx' if the code is not recognized.
$language = get_language_name( $id )
Return the name of the language that corresponds to the given language code (any ISO639 code)
The language codes are taken from SIL International https://iso639-3.sil.org. Please, check the terms of use listed at https://iso639-3.sil.org/code_tables/download_tables. The current version uses the UTF-8 tables distributed in "iso-639-3_Code_Tables_20200130.zip" from that website. This module adds some non-standard codes that are not specified in the original tables to be compatible with some ad-hoc solutions in some resources and
This module provides the definitions of language groups according to ISO 639-5. It allows to retrieve the languages inside of a group and the parent in the language tree for any given language supported by the standard.
use ISO::639::5 qw/:all/;
print join(' ',language_group('gmw'));
print join(' ',language_group('gem'));
print join(' ',language_group_children('gem'));
print language_parent('afr');
print language_parent('gmw');
The package provides the tool langgroup that can be used to retrieve languages in a given language group or group languages according to language groups. Look at the man-page of the tool for more information.
This module provides language scripts and territories
use ISO::15924 qw/:all/;
$script = script_of_string('То је моја мачка.', 'srp');
$script = script_of_string('你是我妈妈。');
%scripts = script_of_string('То је моја мачка. Ti si moja majka.');
$region = &default_territory('por')
$script = &default_script('tur')
The package provides the tool langscript that can be used to detect the script for a given string based on Unicode script patterns. A language can be given to narrow down the search. Look at the man-pages for more information.
