=pod =head1 NAME Locale::Codes::LangVar - standard codes for language variation identification =head1 SYNOPSIS use Locale::Codes::LangVar; $lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic' $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langvar_codes(); @names = all_langvar_names(); =head1 DESCRIPTION The C<Locale::Codes::LangVar> module provides access to standard codes used for identifying language variations, such as those as defined in the IANA language registry. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language registry codes will be used. =head1 SUPPORTED CODE SETS There are several different code sets you can use for identifying language variations. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lvar = code2langvar('arevela','alpha'); $lvar = code2langvar('arevela',LOCALE_LANGVAR_ALPHA); The codesets currently supported are: =over 4 =item B<alpha> This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian. This code set is identified with the symbol C<LOCALE_LANGVAR_ALPHA>. This is the default code set. =back =head1 ROUTINES =over 4 =item B<code2langvar ( CODE [,CODESET] [,'retired'])> =item B<langvar2code ( NAME [,CODESET] [,'retired'])> =item B<langvar_code2code ( CODE ,CODESET ,CODESET2 )> =item B<all_langvar_codes ( [CODESET] [,'retired'])> =item B<all_langvar_names ( [CODESET] [,'retired'])> =item B<Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )> =item B<Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )> =item B<Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )> =item B<Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )> =item B<Locale::Codes::LangVar::delete_langvar_alias ( NAME )> =item B<Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] )> =item B<Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] )> =item B<Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] )> These routines are all documented in the Locale::Codes::API man page. =back =head1 SEE ALSO =over 4 =item B<Locale::Codes> The Locale-Codes distribution. =item B<Locale::Codes::API> The list of functions supported by this module. =item B<http://www.iana.org/assignments/language-subtag-registry> The IANA language subtag registry. =back =head1 AUTHOR See Locale::Codes for full author history.
