NAME

I18N::Handle - A common i18n handler for web frameworks and applications.

***THIS MODULE IS STILL IN DEVELOPMENT***

DESCRIPTION

I18N::Handle is a common handler for web frameworks and applications.

You can use App::I18N to generate po/mo files, then use this module

to handle these languages.

SYNOPSIS

Ideas are welcome. just drop me a line.

option import takes the same arguments as Locale::Maketext::Lexicon takes. it's language => [ format => source ].

use I18N::Handle;
my $hl = I18N::Handle->new( 
            import => {
                    en => [ Gettext => 'po/en.po' ],
                    fr => [ Gettext => 'po/fr.po' ],
                    jp => [ Gettext => 'po/jp.po' ],
            })->accept( qw(en fr) )->speak( 'en' );

Or a simple way to import gettext po files: This will transform the args to the args that import option takes:

use I18N::Handle;
my $hl = I18N::Handle->new( 
            Gettext => {
                    en => 'po/en.po',
                    fr => 'po/fr.po',
                    jp => [ 'po/jp.po' , 'po2/jp.po' ],
            })->accept( qw(en fr) )->speak( 'en' );


print _('Hello world');

$hl->speak( 'fr' );
$hl->speak( 'jp' );
$hl->speaking;  # return 'jp'

my @langs = $hl->can_speak();  # return 'en', 'fr', 'jp'

USE CASES

Handling po files

$hl = I18N::Handle->new( 
        po => 'path/to/po',
        style => 'gettext'          # use gettext style format (default)
            )->speak( 'en' );

print _('Hello world');

Handling locale

If you need to bind the locale directory structure like this:

po/en/LC_MESSAGES/app.po
po/en/LC_MESSAGES/app.mo
po/zh_tw/LC_MESSAGES/app.po
po/zh_tw/LC_MESSAGES/app.mo

You can just pass the locale option:

$hl = I18N::Handle->new(
        locale => 'path/to/locale'
        )->speak( 'en_US' );

Singleton

If you need a singleton I18N::Handle, this is a helper function to return the singleton object:

$hl = I18N::Handle->singleton( locale => 'path/to/locale' );

In your applications, might be like this:

sub get_i18n {
    my $class = shift;
    return I18N::Handle->singleton( ... options ... )
}

Connect to a remote i18n server

not implemented yet

Connect to a translation server:

$handle = I18N::Handle->new( 
        server => 'translate.me' )->speak( 'en_US' );

Binding with database

not implemented yet

Connect to a database:

$handle = I18N::Handle->new(
        dsn => 'DBI:mysql:database=$database;host=$hostname;port=$port;'
        );

Binding with Google translation service

not implemented yet

Connect to google translation:

$handle = I18N::Handle->new( google => "" );

OPTIONS

format => { language => source , ... }

Format could be Gettext | Msgcat | Slurp | Tie.

use I18N::Handle;
my $hl = I18N::Handle->new( 
            Gettext => {
                    en => 'po/en.po',
                    fr => 'po/fr.po',
                    jp => [ 'po/jp.po' , 'po2/jp.po' ],
            });
$hl->speak( 'en' );
po => 'path' | [ path1 , path2 ]

Suppose you have these files:

po/en.po
po/zh_TW.po

When using:

I18N::Handle->new( po => 'po' );

will be found. can you can get these langauges:

[ en , zh-tw ]
locale => 'path' | [ path1 , path2 ]
import => Arguments to Locale::Maketext::Lexicon

OPTIONAL OPTIONS

style => style ... (Optional)

The style could be gettext.

loc => global loc function name (Optional)

The default loc function name is _.
