=head1 NAME

vCard::AddressBook - Read, write, and edit vCard address books

=head1 SYNOPSIS

    use vCard::AddressBook;

    # create the object
    my $address_book = vCard::AddressBook->new();

    # these methods load vCard formatted data
    $address_book->load_file('/path/file.vcf');
    $address_book->load_string($string);

    my $vcard = $address_book->add_vcard; # returns a vCard object
    $vcard->full_name('Bruce Banner, PhD');
    $vcard->family_names(['Banner']);
    $vcard->given_names(['Bruce']);
    $vcard->email_addresses([
        { type => ['work'], address => '[e-mail]' },
        { type => ['home'], address => '[e-mail]'      },
    ]);

    # $address_book->vcards() returns an arrayref of vCard objects
    foreach my $vcard (@{ $address_book->vcards() }) {
        print $vcard->full_name() . "\n";
        print $vcard->email_addresses->[0]->{address} . "\n";
    }

    # these methods output data in vCard format
    my $file   = $address_book->as_file('/path/file.vcf'); # write to a file
    my $string = $address_book->as_string();


=head1 DESCRIPTION

A vCard is a digital business card.  L and vCard::AddressBook provide an
API for parsing, editing, and creating vCards.

This module is built on top of L and L
and provides a more intuitive user interface.


=head1 ENCODING AND UTF-8

=head2 Constructor Arguments

The 'encoding_in' and 'encoding_out' constructor parameters allow you to read
and write vCard files with any encoding.  Examples of valid values are
'UTF-8', 'Latin1', and 'none'.

Both parameters default to 'UTF-8' and this should just work for the vast
majority of people.  The latest vCard RFC 6350 only allows UTF-8 as an encoding
so most people should not need to use either parameter.

=head2 MIME encodings

vCard RFC 6350 only allows UTF-8 but it still permits 8bit MIME encoding
schemes such as Quoted-Printable and Base64 which are supported by this module.

=head2 Getting and setting values on a vCard object

If you set values on a vCard object they must be decoded values.  The
only exception to this rule is if you are messing around with the
'encoding_out' constructor arg.

When you get values from a vCard object they will be decoded values.


=head1 METHODS

=cut

has encoding_in  => ( is => 'rw', default => sub {'UTF-8'} );
has encoding_out => ( is => 'rw', default => sub {'UTF-8'} );
has vcards       => ( is => 'rw', default => sub { [] } );

with 'vCard::Role::FileIO';

=head2 add_vcard()

Creates a new vCard object and adds it to the address book.  Returns a L
object.

=cut

sub add_vcard {
    my ($self) = @_;
    my $vcard = vCard->new(
        {   encoding_in  => $self->encoding_in,
            encoding_out => $self->encoding_out,
        }
    );
    push @{ $self->vcards }, $vcard;
    return $vcard;
}

=head2 load_file($filename)

Load and parse the contents of $filename.  Returns $self so the method can be
chained.

=cut

sub load_file {
    my ( $self, $filename ) = @_;

    my $file   = $self->_path($filename);
    my $string = $file->slurp( $self->_iomode_in );

    $self->load_string($string);

    return $self;
}

=head2 load_string($string)

Load and parse the contents of $string.  This method assumes that $string is
decoded (but not MIME decoded).  Returns $self so the method can be chained.

=cut

sub load_string {
    my ( $self, $string ) = @_;

    die <
ERROR: Either there is no END in this vCard or there is a problem with the line
endings.  Note that the vCard RFC requires line endings delimited by \\r\\n
regardless of your operating system.  Windows :crlf mode will strip out the \\r
so don't use that.
