DESCRIPTION

This module provides an additional getext methods for static domain and category handling.

SYNOPSIS

my $loc = Locale::Text::TextDomain::OO->new(
    plugins => [ qw (
        Expand::Gettext
        ...
    )],
    ...
);

Optional type formatting or grammer stuff see Locale::Utils::PlaceholderNamed for possible methods.

$loc->expand_gettext->modifier_code($code_ref);

SUBROUTINES/METHODS

method expand_gettext

Returns the Locale::Utils::PlaceholderNamed object to be able to set some options.

my $expander_object = $self->expand_gettext;

e.g.

$self->expand_gettext->modifier_code(
    sub {
        my ( $value, $attribute ) = @_;
        if ( $attribute eq 'num' ) {
            # modify that numeric $value
            # e.g. change 1234.56 to 1.234,56 or 1,234.56
            ...
        }
        elsif ( $attribute eq 'accusative' ) {
            # modify the string with that grammer rule
            # e.g. needed for East-European languages
            # write grammer rules only on msgstr/msgstr_plural[n]
            # and not on msgid
            ...
        }
        ...
        return $value;
    },
);

translation methods

How to build the method name?

Use __ and append this with "n", "p" and/or "x" in alphabetic order.

|---------+--------------------------------------------------------------|
| __      | Special marked for extraction.                               |
| n       | Using plural forms.                                          |
| p       | Context is the first parameter.                              |
| x       | Last parameters as hash/hash_ref are for named placeholders. |
'------------------------------------------------------------------------'

method __

Translate only

print $loc->__(
    'Hello World!',
);

method __x

Expand named placeholders

print $loc->__x(
    'Hello {name}!',
    # hash or hash_ref
    name => 'Steffen',
);

method __n

Plural

print $loc->__n(
    'one file read',       # Singular
    'a lot of files read', # Plural
    $file_count,           # number to select the right plural form
);

method __nx

Plural and expand named placeholders

print $loc->__nx(
    '{count:num} file read',
    '{count:num} files read',
    $file_count,
    # hash or hash_ref
    count => $file_count,
);

What is the meaning of {count:num} or alternative {count :num}?

That is a attribute. If there is such an attribute like :num and the modifier_code is set, the placeholder value will be modified before replacement.

Think about the attribute names. Too technical names are able to destroy the translation process by translation office stuff.

method __p

Context

print $loc->__p (
    'time', # Context
    'to',
);

print $loc->__p (
    'destination', # Context
    'to',
);

method __px

Context and expand named placeholders

print $loc->__px (
    'destination',
    'from {town_from} to {town_to}',
    # hash or hash_ref
    town_from => 'Chemnitz',
    town_to   => 'Erlangen',
);

method __np

Context and plural

print $loc->__np (
    'maskulin',
    'Dear friend',
    'Dear friends',
    $friends,
);

method __npx

Context, plural and expand named placeholders

print $loc->__npx(
    'maskulin',
    'Mr. {name} has {count:num} book.',
    'Mr. {name} has {count:num} books.',
    $book_count,
    # hash or hash_ref
    name  => $name,
    count => $book_count,
);

Methods to mark the translation for extraction only

How to build the method name?

Use N__ and append this with "n", "p" and/or "x" in alphabetic order.

| __      | Special marked for extraction.                               |

| p       | Context is the first parameter.                              |
| x       | Last parameters as hash/hash_ref are for named placeholders. |

methods N, Nx, Nn, Nnx, Np, Npx, Nnp, Nnpx

The extractor looks for __('... and has no problem with $loc->N__('....

This is the idea of the N-Methods.

$loc->N__('...');
$loc->N__x('...', ...);
...
