NAME

Activator::Emailer - Send emails from anywhere within a project in the same way using role-based configuration.

SYNOPSIS

Configure defaults with Activator::Registry configuration (See CONFIGURATION), then:

  use Activator::Emailer;
  my $tt_vars = { data => 'any data your template needs',
                  other_data => $my_data,
                };
  my $mailer = Activator::Emailer->new(
     To          => 'person@test.com',
     Cc          => 'other@test.com, other2@test.com'
     Subject     => 'Test Subject',
  );
  $mailer->send( $tt_vars );

Reuse the mailer object to send another mail to someone else using a different body template, plus an attachment:

  $mailer->set_cc( '' );
  $mailer->set_to( 'someone_else@other-domain.com' );
  $mailer->set_html_body( '/path/to/html_body.tt' );
  $tt_vars = $my_alternate_data_hashref;
  $mailer->attach( Type        => 'application/pdf',
                   Path        => 'path/to/doc.pdf',
                   Filename    => 'doc.pdf',
                   Disposition => 'attachment' );
  $mailer->send( $tt_vars );

DESCRIPTION

Activator::Emailer is a simple wrapper to Mime::Lite, Template::Toolkit and Email::Send that uses your project's Activator::Registry to facilitate easy sending of multipart text/html email from any module in your project. Emailer can talk to any MTAs that Email::Send can.

Full Example

  use Activator::Emailer;
  my $tt_vars = { data => $my_data,
                  other_data => 'any data your template needs'
                };
  my $mailer = Activator::Emailer->new(
     From        => 'no-reply@test.com',
     To          => 'person@test.com',
     Cc          => 'other@test.com, other2@test.com'
     Subject     => 'Test Subject',
     html_header => '/path/to/html_header.tt',
     html_body   => '/path/to/html_body.tt',
     html_footer => '/path/to/html_footer.tt',
     email_wrap  => '/path/to/email/wrapper/template',
     mailer_type => 'Gmail',
     mailer_args => [ username => 'user@gmail.com',
                      password => '123456'
                    ],
  );
  $mailer->attach( Type        => 'application/pdf',
                   Path        => 'path/to/doc.pdf',
                   Filename    => 'invoice.pdf',
                   Disposition => 'attachment'
  $mailer->send( $tt_vars );

The next section shows how to simplify this.

CONFIGURATION

As is seen in the previous section, a lot of information is needed to send an email. Fortunately, most of the information is reusable. You can utilize Activator::Registry to simplify creation of emails:

  'Activator::Registry':
    'Activator::Emailer': 
      From: noreply@domain.com
      mailer_type: Gmail     # any of the send methods Email::Send supports
      mailer_args:           # any of the args required by your Email::Send::<TYPE>
        - username: <username>
        - password: <password>
      html_header: /fully/qualified/path/to/header/tt/template
      html_footer: relative/path/to/footer/tt/template
      html_body:   relative/path/to/body/tt/template
      email_wrap:  /path/to/email/wrapper/template
      tt_options:
        INCLUDE_PATH: /path/to/tt/templates

In the simplist case, you can now send as such:

  my $mailer = Activator::Emailer->new(
     To          => 'person@test.com',
     Subject     => 'Test Subject',
  );
  $mailer->send( { data => $my_data } );

TEMPLATES SETUP

You must create 4 template for emails to work. Each template has a variable Activator_Emailer_format available so you can do HTML or text specific template blocks. Note that it is suggested that you utilize the TT chomping close tag (-%]) to maintain format.

File 1: html_header

This is the most basic header, but you can add as much HTML as you like, including limited style and script tags:

 <html>
 <body>

File 2: html_body

Put whatever html you like in this section.

 <h1>Body</h1>
 <p>This is only an example</p>
 [% IF Activator_Emailer_format == 'text' -%]
 ========================================
 [% ELSE -%]
 <hr>
 [% END -%]

This is the most basic footer, but you can add as much HTML as you like:

 </body>
 </html>

File 4: email_wrap.tt

Copy this verbatim, trim the leading space:

  [% USE HTML.Strip -%]
  [% BLOCK html_header -%]
  [% INCLUDE html_header %]
  [% END -%]
  [% BLOCK html_footer %]
  [% INCLUDE html_footer %]
  [% END -%]
  [% BLOCK body -%]
  [% INCLUDE html_body %]
  [% END -%]
  [% IF format == 'text' -%]
  [% FILTER html_strip emit_spaces = 0 -%]
  [% INCLUDE body %]
  [% END -%]
  [% ELSE -%]
  [% INCLUDE html_header -%]
  [% INCLUDE body %]
  [% INCLUDE html_footer -%]
  [% END -%]

Note that you can put the files anywhere. See CONFIGURATION for more details.

METHODS

new( %args )

Create an Activator::Emailer object. Valid %args are described below.

  • The following are sent directly to MIME::Lite, and likewise injected directly into the mail header ( hence the capitalization )

     * From - A single email address
     * To - A single email address
     * Subject - A string
     * Cc - A string consisting of a comma separated list of email addresses
  • The following are used for sending with Email::Send:

     * mailer_type - Any valid Email::Send subclass
     * mailer_args - Any args to pass to the <mailer_type> class
  • The following are used with Template::Toolkit

     * tt_include_path - The INCLUDE_PATH for template toolkit. Useful
                         for reusing project templates within an email
  • The following are custom to Activator::Emailer:

     * html_header - A template file or string to use for the top of the
                     HTML portion of the email
     * html_footer - A template file or string to use for the bottom of
                     the HTML portion of the email
     * html_body   - A template file or string to use for the html portion.
                     of the email Also, this will be stripped of all HTML
                     tags ( using HTML::Strip ) and used for the body of
                     the text portion of the email.

send( $tt_vars )

Send the email using $tt_vars for the Template::Toolkit process method.

attach( %args )

Attach an item to this email. When send() is called, %args is just passed through to the MIME::Lite attach function.

valid_email ( $email )

Sanity check on the email address. Throws exception on failure.

setters

Each value that can be passed to new() can be modified by calling set_<VALUE>, where value is lowercased.
