#pod =head1 SYNOPSIS
#pod
#pod   # Prepare the message
#pod   my $body = <<'AMBUSH_READY';
#pod   Dear Santa
#pod
#pod   I have killed Bun Bun.
#pod
#pod   Yes, I know what you are thinking... but it was actually a total accident.
#pod
#pod   I was in a crowded line at a BayWatch signing, and I tripped, and stood on
#pod   his head.
#pod
#pod   I know. Oops! :/
#pod
#pod   So anyways, I am willing to sell you the body for $1 million dollars.
#pod
#pod   Be near the pinhole to the Dimension of Pain at midnight.
#pod
#pod   Alias
#pod
#pod   AMBUSH_READY
#pod
#pod   # Create and send the email in one shot
#pod   Email::Stuffer->from     ('cpan@ali.as'             )
#pod                 ->to       ('santa@northpole.org'     )

#pod =head1 DESCRIPTION
#pod
#pod B<The basics should all work, but this module is still subject to
#pod name and/or API changes>
#pod
#pod Email::Stuffer, as its name suggests, is a fairly casual module used
#pod to stuff things into an email and send them. It is a high-level module
#pod designed for ease of use when doing a very specific common task, but
#pod implemented on top of the light and tolerable Email:: modules.
#pod
#pod Email::Stuffer is typically used to build emails and send them in a single
#pod statement, as seen in the synopsis. And it is certain only for use when
#pod creating and sending emails. As such, it contains no email parsing
#pod capability, and little to no modification support.
#pod
#pod To re-iterate, this is very much a module for those "slap it together and
#pod fire it off" situations, but that still has enough grunt behind the scenes
#pod to do things properly.
#pod
#pod =head2 Default Transport
#pod
#pod Although it cannot be relied upon to work, the default behaviour is to
#pod use C<sendmail> to send mail, if you don't provide the mail send channel
#pod with either the C<transport> method, or as an argument to C<send>.
#pod
#pod (Actually, the choice of default is delegated to
#pod L<Email::Sender::Simple>, which makes its own choices.  But usually, it
#pod uses C<sendmail>.)
#pod
#pod =head2 Why use this?
#pod
#pod Why not just use L<Email::Simple> or L<Email::MIME>? After all, this just adds
#pod another layer of stuff around those. Wouldn't using them directly be better?
#pod
#pod Certainly, if you know EXACTLY what you are doing. The docs are clear enough,
#pod but you really do need to have an understanding of the structure of MIME
#pod emails. This structure is going to be different depending on whether you have
#pod text body, HTML, both, with or without an attachment etc.
#pod
#pod Then there's brevity... compare the following roughly equivalent code.
#pod
#pod First, the Email::Stuffer way.
#pod
#pod   Email::Stuffer->to('Simon Cozens<simon@somewhere.jp>')
#pod                 ->from('Santa@northpole.org')
#pod                 ->text_body("You've been good this year. No coal for you.")
#pod                 ->attach_file('choochoo.gif')
#pod                 ->send;
#pod
#pod And now doing it directly with a knowledge of what your attachment is, and
#pod what the correct MIME structure is.
#pod
#pod   use Email::MIME;
#pod   use Email::Sender::Simple;
#pod   use IO::All;
#pod
#pod   Email::Sender::Simple->try_to_send(
#pod     Email::MIME->create(
#pod       header => [
#pod           To => 'simon@somewhere.jp',
#pod           From => 'santa@northpole.org',
#pod       ],
#pod       parts => [
#pod           Email::MIME->create(
#pod             body => "You've been a good boy this year. No coal for you."
#pod           ),
#pod           Email::MIME->create(
#pod             body => io('choochoo.gif'),
#pod             attributes => {
#pod                 filename => 'choochoo.gif',
#pod                 content_type => 'image/gif',
#pod             },
#pod          ),
#pod       ],
#pod     );
#pod   );
#pod
#pod Again, if you know MIME well, and have the patience to manually code up
#pod the L<Email::MIME> structure, go do that, if you really want to.
#pod
#pod Email::Stuffer as the name suggests, solves one case and one case only:
#pod generate some stuff, and email it to somewhere, as conveniently as
#pod possible. DWIM, but do it as thinly as possible and use the solid
#pod Email:: modules underneath.
#pod
#pod =head1 COOKBOOK
#pod
#pod Here is another example (maybe plural later) of how you can use
#pod Email::Stuffer's brevity to your advantage.
#pod
#pod =head2 Custom Alerts
#pod
#pod   package SMS::Alert;
#pod   use base 'Email::Stuffer';
#pod
#pod   sub new {
#pod     shift()->SUPER::new(@_)
#pod            ->from('monitor@my.website')
#pod            # Of course, we could have pulled these from
#pod            # $MyConfig->{support_tech} or something similar.
#pod            ->to('0416181595@sms.gateway')
#pod            ->transport('SMTP', { host => '123.123.123.123' });
#pod   }
#pod
#pod Z<>
#pod
#pod   package My::Code;
#pod
#pod   unless ( $Server->restart ) {
#pod           # Notify the admin on call that a server went down and failed
#pod           # to restart.
#pod           SMS::Alert->subject("Server $Server failed to restart cleanly")
#pod                     ->send;
#pod   }
#pod
#pod =head1 METHODS
#pod
#pod As you can see from the synopsis, all methods that B<modify> the
#pod Email::Stuffer object returns the object, and thus most normal calls are
#pod chainable.
#pod
#pod However, please note that C<send>, and the group of methods that do not
#pod change the Email::Stuffer object B<do not> return the object, and thus
#pod B<are not> chainable.

#pod

#pod of the line was dropped and every new line character could be changed
#pod to one space (and vice versa).  Version 0.015 (and later) does not set
#pod flowed format automatically anymore and so text body is really plain
#pod text.  If you want to use old behavior of "advanced" flowed formatting,

=head1 NAME

Email::Stuffer - A more casual approach to creating and sending Email:: emails

=head1 VERSION

version 0.018

=head1 SYNOPSIS

# Prepare the message
  my $body = <<'AMBUSH_READY';
  Dear Santa

I have killed Bun Bun.

Yes, I know what you are thinking... but it was actually a total accident.

I was in a crowded line at a BayWatch signing, and I tripped, and stood on
  his head.

I know. Oops! :/

So anyways, I am willing to sell you the body for $1 million dollars.

Be near the pinhole to the Dimension of Pain at midnight.

Alias

AMBUSH_READY

# Create and send the email in one shot
  Email::Stuffer->from     ('cpan@ali.as'             )
                ->to       ('santa@northpole.org'     )
                ->bcc      ('bunbun@sluggy.com'       )
                ->text_body($body                     )
                ->attach_file('dead_bunbun_faked.gif' )
                ->send;

=head1 DESCRIPTION

B<The basics should all work, but this module is still subject to
name and/or API changes>

Email::Stuffer, as its name suggests, is a fairly casual module used
to stuff things into an email and send them. It is a high-level module
designed for ease of use when doing a very specific common task, but
implemented on top of the light and tolerable Email:: modules.

Email::Stuffer is typically used to build emails and send them in a single
statement, as seen in the synopsis. And it is certain only for use when
creating and sending emails. As such, it contains no email parsing
capability, and little to no modification support.

To re-iterate, this is very much a module for those "slap it together and
fire it off" situations, but that still has enough grunt behind the scenes
to do things properly.

=head2 Default Transport

Although it cannot be relied upon to work, the default behaviour is to
use C<sendmail> to send mail, if you don't provide the mail send channel
with either the C<transport> method, or as an argument to C<send>.

(Actually, the choice of default is delegated to
L<Email::Sender::Simple>, which makes its own choices.  But usually, it
uses C<sendmail>.)

=head2 Why use this?

Why not just use L<Email::Simple> or L<Email::MIME>? After all, this just adds
another layer of stuff around those. Wouldn't using them directly be better?

Certainly, if you know EXACTLY what you are doing. The docs are clear enough,
but you really do need to have an understanding of the structure of MIME
emails. This structure is going to be different depending on whether you have
text body, HTML, both, with or without an attachment etc.

Then there's brevity... compare the following roughly equivalent code.

First, the Email::Stuffer way.

Email::Stuffer->to('Simon Cozens<simon@somewhere.jp>')
                ->from('Santa@northpole.org')
                ->text_body("You've been good this year. No coal for you.")
                ->attach_file('choochoo.gif')
                ->send;

And now doing it directly with a knowledge of what your attachment is, and
what the correct MIME structure is.

use Email::MIME;
  use Email::Sender::Simple;
  use IO::All;

Email::Sender::Simple->try_to_send(
    Email::MIME->create(
      header => [
          To => 'simon@somewhere.jp',
          From => 'santa@northpole.org',
      ],
      parts => [
          Email::MIME->create(
            body => "You've been a good boy this year. No coal for you."
          ),
          Email::MIME->create(
            body => io('choochoo.gif'),
            attributes => {
                filename => 'choochoo.gif',
                content_type => 'image/gif',
            },
         ),
      ],
    );
  );

Again, if you know MIME well, and have the patience to manually code up
the L<Email::MIME> structure, go do that, if you really want to.

Email::Stuffer as the name suggests, solves one case and one case only:
generate some stuff, and email it to somewhere, as conveniently as
possible. DWIM, but do it as thinly as possible and use the solid
Email:: modules underneath.

=head1 METHODS

As you can see from the synopsis, all methods that B<modify> the
Email::Stuffer object returns the object, and thus most normal calls are
chainable.

However, please note that C<send>, and the group of methods that do not
change the Email::Stuffer object B<do not> return the object, and thus
B<are not> chainable.

=head2 new

Creates a new, empty, Email::Stuffer object.

You can pass a hashref of properties to set, including:

=over 4

=item *

from

=item *

bcc

=item *

reply_to

=item *

subject

=item *

text_body

=item *

html_body

=item *

transport

=back

The to, cc, bcc, and reply_to headers properties may be provided as array
references.  The array's contents will be used as the list of arguments to the
setter.

=head2 header_names

Returns, as a list, all of the headers currently set for the Email
For backwards compatibility, this method can also be called as B[headers].

=head2 parts

Returns, as a list, the L<Email::MIME> parts for the Email

=head2 header $header => $value

Sets a named header in the email. Multiple calls with the same $header
will overwrite previous calls $value.

=head2 to @addresses

Sets the To: header in the email

=head2 from $address

Sets the From: header in the email

=head2 reply_to $address

Sets the Reply-To: header in the email

=head2 cc @addresses

Sets the Cc: header in the email

=head2 bcc @addresses

Sets the Bcc: header in the email

=head2 subject $text

Sets the Subject: header in the email

=head2 text_body $body [, $attribute => $value, ... ]

Sets the text body of the email. Appropriate headers are set for you.
You may override MIME attributes as needed. See the C<attributes>
parameter to L<Email::MIME/create> for the headers you can set.

If C<$body> is undefined, this method will do nothing.

Prior to Email::Stuffer version 0.015 text body was marked as flowed,
which broke all pre-formated body text.  Empty space at the beggining
of the line was dropped and every new line character could be changed
to one space (and vice versa).  Version 0.015 (and later) does not set
flowed format automatically anymore and so text body is really plain
text.  If you want to use old behavior of "advanced" flowed formatting,
set flowed format manually by: C<< text_body($body, format => 'flowed') >>.

=head2 html_body $body [, $header => $value, ... ]

Sets the HTML body of the email. Appropriate headers are set for you.
You may override MIME attributes as needed. See the C<attributes>
parameter to L<Email::MIME/create> for the headers you can set.

If C<$body> is undefined, this method will do nothing.

=head2 attach $contents [, $attribute => $value, ... ]

Adds an attachment to the email. The first argument is the file contents
followed by (as for text_body and html_body) the list of headers to use.
Email::Stuffer will I<try> to guess the headers correctly, but you may wish
to provide them anyway to be sure. Encoding is Base64 by default. See
the C<attributes> parameter to L<Email::MIME/create> for the headers you
can set.

=head2 attach_file $file [, $attribute => $value, ... ]

Attachs a file that already exists on the filesystem to the email.
C<attach_file> will attempt to auto-detect the MIME type, and use the
file's current name when attaching. See the C<attributes> parameter to
L<Email::MIME/create> for the headers you can set.

=head2 transport

$stuffer->transport( $moniker, @options )

$stuffer->transport( $transport_obj )

The C<transport> method specifies the L<Email::Sender> transport that
you want to use to send the email, and any options that need to be
used to instantiate the transport.  C<$moniker> is used as the transport
name; if it starts with an equals sign (C<=>) then the text after the
sign is used as the class.  Otherwise, the text is prepended by
C<Email::Sender::Transport::>.

Alternatively, you can pass a complete transport object (which must be
an L<Email::Sender::Transport> object) and it will be used as is.

=head2 email

Creates and returns the full L<Email::MIME> object for the email.

=head2 as_string

Returns the string form of the email. Identical to (and uses behind the
scenes) Email::MIME-E<gt>as_string.

=head2 send

$stuffer->send;

$stuffer->send({ to => [ $to_1, $to_2 ], from => $sender });

Sends the email via L<Email::Sender::Simple>.
L<Envelope information|Email::Sender::Manual::QuickStart/"envelope information">
can be specified in a hash reference.

On failure, returns false.

=head2 send_or_die

$stuffer->send_or_die;

$stuffer->send_or_die({ to => [ $to_1, $to_2 ], from => $sender });

Sends the email via L<Email::Sender::Simple>.
L<Envelope information|Email::Sender::Manual::QuickStart/"envelope information">
can be specified in a hash reference.

On failure, throws an exception.

=head1 COOKBOOK

Here is another example (maybe plural later) of how you can use
Email::Stuffer's brevity to your advantage.

=head2 Custom Alerts

package SMS::Alert;
  use base 'Email::Stuffer';

sub new {
    shift()->SUPER::new(@_)
           ->from('monitor@my.website')
           # Of course, we could have pulled these from
           # $MyConfig->{support_tech} or something similar.
           ->to('0416181595@sms.gateway')
           ->transport('SMTP', { host => '123.123.123.123' });
  }

Z<>

package My::Code;

unless ( $Server->restart ) {
          # Notify the admin on call that a server went down and failed
          # to restart.
          SMS::Alert->subject("Server $Server failed to restart cleanly")
                    ->send;
  }
