Email::Simple(3)

NAME
Email::Simple - simple parsing of RFC2822 message format and headers

VERSION
version 2.203

SYNOPSIS
  use Email::Simple;
  my $email = Email::Simple->new($text);

  my $from_header = $email->header("From");
  my @received = $email->header("Received");

  $email->header_set("From", 'Simon Cozens <simon@cpan.org>');

  my $old_body = $email->body;
  $email->body_set("Hello world\nSimon");

  print $email->as_string;

...or, to create a message from scratch...

  my $email = Email::Simple->create(
      header => [
        From    => 'casey@geeknest.com',
        To      => 'drain@example.com',
        Subject => 'Message in a bottle',
      ],
      body => '...',
  );

  $email->header_set( 'X-Content-Container' => 'bottle/glass' );

  print $email->as_string;

DESCRIPTION
The Email:: namespace was begun as a reaction against the increasing complexity and bugginess of Perl's existing email modules. "Email::*" modules are meant to be simple to use and to maintain, pared to the bone, fast, minimal in their external dependencies, and correct.

METHODS

  new
  my $email = Email::Simple->new($message, \%arg);

This method parses an email from a scalar containing an RFC2822 formatted message and returns an object. $message may be a reference to a message string, in which case the string will be altered in place. This can result in significant memory savings.

If you want to create a message from scratch, you should use the "create" method.

Valid arguments are:

  header_class - the class used to create new header objects
                 The named module is not 'require'-ed by Email::Simple!

  create
  my $email = Email::Simple->create(header => [ @headers ], body => '...');

This method is a constructor that creates an Email::Simple object from a set of named parameters. The "header" parameter's value is a list reference containing a set of headers to be created. The "body" parameter's value is a scalar value holding the contents of the message body. Line endings in the body will normalized to CRLF.

If no "Date" header is specified, one will be provided for you based on the "gmtime" of the local machine. This is because the "Date" field is a required header and is a pain in the neck to create manually for every message. The "From" field is also a required header, but it is not provided for you.

  header_obj
  my $header = $email->header_obj;

This method returns the object representing the email's header. For the interface for this object, see Email::Simple::Header.

  header_obj_set
  $email->header_obj_set($new_header_obj);

This method substitutes the given new header object for the email's existing header object.

  header
  my @values = $email->header($header_name);
  my $first  = $email->header($header_name);

In list context, this returns every value for the named header. In scalar context, it returns the first value for the named header.

  header_set
    $email->header_set($field, $line1, $line2, ...);

Sets the header to contain the given data. If you pass multiple lines in, you get multiple headers, and order is retained. If no values are given to set, the header will be removed from to the message entirely.

  header_names
    my @header_names = $email->header_names;

This method returns the list of header names currently in the email object. These names can be passed to the "header" method one-at-a-time to get header values. You are guaranteed to get a set of headers that are unique. You are not guaranteed to get the headers in any order at all.

For backwards compatibility, this method can also be called as headers.

  header_pairs
  my @headers = $email->header_pairs;

This method returns a list of pairs describing the contents of the header. Every other value, starting with and including zeroth, is a header name and the value following it is the header value.

  body
Returns the body text of the mail.

  body_set
Sets the body text of the mail.

  as_string
Returns the mail as a string, reconstructing the headers.

  crlf
This method returns the type of newline used in the email. It is an accessor only.

  default_header_class
This returns the class used, by default, for header objects, and is provided for subclassing. The default default is Email::Simple::Header.

CAVEATS
Email::Simple handles only RFC2822 formatted messages. This means you cannot expect it to cope well as the only parser between you and the outside world, say for example when writing a mail filter for invocation from a .forward file (for this we recommend you use Email::Filter anyway).
