=head1 NAME

Locale::gettext - message handling functions

=head1 SYNOPSIS

use Locale::gettext;
    use POSIX;     # Needed for setlocale()

setlocale(LC_MESSAGES, "");

# OO interface
    my $d = Locale::gettext->domain("my_program");

print $d->get("Welcome to my program"), "\n";
            # (printed in the local language)

# Direct access to C functions
    textdomain("my_program");

print gettext("Welcome to my program"), "\n";
            # (printed in the local language)

=head1 DESCRIPTION

The gettext module permits access from perl to the gettext() family of
functions for retrieving message strings from databases constructed
to internationalize software.

=item $d = Locale::gettext->domain(DOMAIN)

=item $d = Locale::gettext->domain_raw(DOMAIN)

Creates a new object for retrieving strings in the domain B<DOMAIN>
and returns it. C<domain> requests that strings be returned as
Perl strings (possibly with wide characters) if possible while
C<domain_raw> requests that octet strings directly from functions
like C<dgettext()>.

}

=item $d->get(MSGID)

Calls C<dgettext()> to return the translated string for the given
B<MSGID>.

=cut

sub get {
	my ($self, $msgid) = @_;
	$self->_convert(dgettext($self->{domain}, $msgid));
}

=item $d->cget(MSGID, CATEGORY)

Calls C<dcgettext()> to return the translated string for the given
B<MSGID> in the given B<CATEGORY>.

=cut

sub cget {
	my ($self, $msgid, $category) = @_;
	$self->_convert(dcgettext($self->{domain}, $msgid, $category));
}

=item $d->nget(MSGID, MSGID_PLURAL, N)

Calls C<dngettext()> to return the translated string for the given
B<MSGID> or B<MSGID_PLURAL> depending on B<N>.

=cut

sub nget {
	my ($self, $msgid, $msgid_plural, $n) = @_;
	$self->_convert(dngettext($self->{domain}, $msgid, $msgid_plural, $n));
}

=item $d->ncget(MSGID, MSGID_PLURAL, N, CATEGORY)

Calls C<dngettext()> to return the translated string for the given
B<MSGID> or B<MSGID_PLURAL> depending on B<N> in the given
B<CATEGORY>.

	$self->_convert(dcngettext($self->{domain}, $msgid, $msgid_plural, $n, $category));
}

=item $d->dir([NEWDIR])

If B<NEWDIR> is given, calls C<bindtextdomain> to set the
name of the directory where messages for the domain
represented by C<$d> are found. Returns the (possibly changed)
current directory name.

=cut

sub dir {

}

=item $d->codeset([NEWCODE])

For instances created with C<Locale::gettext-E<gt>domain_raw>, manuiplates
the character set of the returned strings.
If B<NEWCODE> is given, calls C<bind_textdomain_codeset> to set the
character encoding in which messages for the domain
represented by C<$d> are returned. Returns the (possibly changed)
current encoding name.

=cut

=back

gettext(), dgettext(), and dcgettext() attempt to retrieve a string
matching their C<msgid> parameter within the context of the current
locale. dcgettext() takes the message's category and the text domain
as parameters while dgettext() defaults to the LC_MESSAGES category
and gettext() defaults to LC_MESSAGES and uses the current text domain.
If the string is not found in the database, then C<msgid> is returned.

ngettext(), dngettext(), and dcngettext() function similarily but
implement differentiation of messages between singular and plural.
See the documentation for the corresponding C functions for details.

textdomain() sets the current text domain and returns the previously
active domain.

I<bindtextdomain(domain, dirname)> instructs the retrieval functions to look
for the databases belonging to domain C<domain> in the directory
C<dirname>

I<bind_textdomain_codeset(domain, codeset)> instructs the retrieval
functions to translate the returned messages to the character encoding
given by B<codeset> if the encoding of the message catalog is known.

=head1 NOTES

Not all platforms provide all of the functions. Functions that are
not available in the underlying C library will not be available in
Perl either.

Perl programs should use the object interface. In addition to being
able to return native Perl wide character strings,
C<bind_textdomain_codeset> will be emulated if the C library does
not provide it.
