# NAME

Locale::Codes::LangVar - standard codes for language variation identification

# 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();

# DESCRIPTION

The `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.

# 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('en','alpha-2');
       $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);

The codesets currently supported are:

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 `LOCALE_LANGVAR_ALPHA`.

  This is the default code set.

# ROUTINES

code2langvar ( CODE [,CODESET] )
langvar2code ( NAME [,CODESET] )
langvar_code2code ( CODE ,CODESET ,CODESET2 )
all_langvar_codes ( [CODESET] )
all_langvar_names ( [CODESET] )
Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] )
Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] )
Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME )
Locale::Codes::LangVar::delete_langvar_alias ( NAME )
