Name

Class::Usul::L10N - Localize text strings

Synopsis

use Class::Usul::L10N;

my $l10n = Class::Usul::L10N->new( {
   localedir => 'path_to_message_catalogs',
   log       => Log::Handler->new, } );

$local_text = $l10n->localize( 'message_to_localize', {
   domains => [ 'message_file', 'another_message_file' ],
   locale  => 'de_DE',
   params  => { name => 'value', }, } );

Description

Localize text strings by looking them up in a GNU Gettext PO message catalog

Configuration and Environment

A POSIX locale id has the form

<language>_<country>.<charset>@<key>=<value>;...

If the use_country attribute is set to true in the constructor call then the language and country are used from locale. By default use_country is false and only the language from the locale attribute is used

Defines the following attributes;

l10n_attributes

Hash ref passed to the File::Gettext constructor

_domains

Names of the mo/po files to search for

_source_name

Either po for Portable Object (the default) or mo for the Machine Object

_use_country

See above

localedir

Base directory to search for mo/po files

lock

Optional IPC::SRLock object passed to File::Gettext

log

Optional logging object

tempdir

Directory to use for temporary files

Subroutines/Methods

BUILDARGS

Monkey with the constructors signature

BUILD

Finish initializing the object

get_po_header

$po_header_hash_ref = $l10n->get_po_header( { locale => 'de' } );

Returns a hash ref containing the keys and values of the PO header record

invalidate_cache

$l10n->invalidate_cache;

Causes a reload of the domain files the next time a message is localized

localize

$local_text = $l10n->localize( $key, $args );

Localizes the message. The message catalog is loaded from a GNU Gettext portable object file. Returns the $key if the message is not in the catalog (and $args->{no_default} is not true). Language is selected by the $args->{locale} attribute. Expands positional parameters of the form [_<n>] if $args->{params} is an array ref of values to substitute. Otherwise expands named attributes of the form {attr_name} using the $args hash for substitution values. If $args->{quote_bind_values} is true the placeholder values are displayed wrapped in quotes, The attribute $args->{count} is passed to the portable object files plural function which is used to select either the singular or plural form of the translation. If $args->{context} is supplied it is prepended to the $key before the lookup in the catalog takes place

Diagnostics

Asserts that the locale attribute is set
