DESCRIPTION

This module provides hash or hash reference based methods.

SYNOPSIS

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

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

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

SUBROUTINES/METHODS

method expand_gettext_named

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

my $expander_object = $self->expand_gettext_named;

e.g.

$self->expand_gettext_name->modifier_code(
    sub {
        my ( $value, $attribute ) = @_;
        if ( $attribute eq 'numf' ) {
            # 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 grammar rule
            # e.g. needed for East-European languages
            # write grammar rules only on msgstr/msgstr_plural[n]
            # and not on msgid
            ...
        }
        ...
        return $value;
    },
);

method locn

The method accepts hash or hash reference parameters.

Translate only

print $loc->locn(
    text => 'Hello World!',
);

print $loc->locn(
    {
        text => 'Hello World!',
    },
);

Expand named placeholders

print $loc->locn(
    text    => 'Hello {name}!',
    replace => { name => 'Steffen' },
);

Plural

print $loc->locn(
    plural => {
        singular => 'one file read',
        plural   => 'a lot of files read',
        count    => $file_count, # number to select the right plural form
    },
);

Plural and expand named placeholders

print $loc->locn(
    plural => {
        singular => '{count:num} file read',
        plural   => '{count:num} files read',
        count    => $file_count,
    },
    replace => {
        count => $file_count,
    },
);

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

That is a attribute. If there is such an attribute like :numf 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.

For better automatic translation use the reserved attribute :num and tag all numeric placeholders.

You are allowed to set multiple attributes like {count :num :numf} The resulting attribute string is then num :numf.

Context

print $loc->locn(
    context => 'time',
    text    => 'to',
);

print $loc->locn(
    context => 'destination',
    text    => 'to',
);

Context and expand named placeholders

print $loc->locn(
    context => 'destination',
    text    => 'from {town_from} to {town_to}',
    replace => {
        town_from => 'Chemnitz',
        town_to   => 'Erlangen',
    },
);

Context and plural

print $loc->locn(
    context => 'maskulin',
    plural  => {
        singular => 'Dear friend',
        plural   => 'Dear friends',
        count    => $friends,
    },
);

Context, plural and expand named placeholders

print $loc->locn(
    context => 'maskulin',
    plural  => {
        singular => 'Mr. {name} has {count:num} book.',
        plural   => 'Mr. {name} has {count:num} books.',
        count    => $book_count,
    },
    replace => {
        name  => $name,
        count => $book_count,
    },
);

method Nlocn to mark the translation for extraction only

The method name is N prefixed so it results in Nlocn.

The extractor looks for locn(... and has no problem with $loc->Nlocn(....

This is the idea of the N-Methods.

my %hash     = $loc->Nlocn( ... );
my $hash_ref = $loc->Nlocn( { ... } );
