=head1 NAME

Locale::TextDomain::OO::Plugin::Expand::BabelFish::Loc - Additional BabelFish methods, prefixed with loc_b

$Id: $

$HeadURL: $

=head1 VERSION

1.025

=head1 DESCRIPTION

This module provides translation with BabelFish writing.

Use this plugin for multiple plurals in one phrase
otherwise use
L<Locale::TextDomain::OO::Plugin::Expand::Gettext::Loc|Locale::TextDomain::OO::Plugin::Expand::Gettext::Loc>
because that writing is much easier to read for a translation office.
Gettext writing has no or constructs and less cryptic chars inside.
The translation office needs no programmer experience.

=head1 SYNOPSIS

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

Optional type formatting or grammar stuff see
L<Locale::Utils::PlaceholderBabelFish|Locale::Utils::PlaceholderBabelFish>
for possible methods.

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

=head1 SUBROUTINES/METHODS

=head2 method expand_babel_fish_loc

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

    my $expander_object = $self->expand_babel_fish_loc;

e.g.

    $self->expand_babel_fish_loc->plural_code(
        $loc->plural_code,
    );

    $self->expand_babel_fish_loc->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;
        },
    );

=head2 translation methods

How to build the method name?

Use loc_b and append this with "p".

 .------------------------------------------------------------------------.
 | Snippet | Description                                                  |
 |---------+--------------------------------------------------------------|
 | p       | Context is the first parameter.                              |
 '------------------------------------------------------------------------'

=head3 method loc_b

Translate only

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

=head3 method loc_bp

Context

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

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

=head2 Methods to mark the translation for extraction only

How to build the method name?

Use Nloc_b and append this with "p".

 .------------------------------------------------------------------------.
 | Snippet | Description                                                  |
 |---------+--------------------------------------------------------------|
 | p       | Context is the first parameter.                              |
 '------------------------------------------------------------------------'

=head3 methods Nloc_b, Nloc_bp

The extractor looks for C<loc_b('...>
and has no problem with C<< $loc->Nloc_b('... >>.

This is the idea of the N-Methods.

    $loc->Nloc_b('...');
    $loc->Nloc_bp('...', '...');
