VERSION

SYNOPSIS
  use Email::MIME::ContentType;

  # Content-Type: text/plain; charset="us-ascii"; format=flowed
  my $ct = 'text/plain; charset="us-ascii"; format=flowed';
  my $data = parse_content_type($ct);

  $data = {
    type       => "text",
    subtype    => "plain",
    attributes => {
      charset => "us-ascii",
      format  => "flowed"
    }
  };

  # Content-Type: application/x-stuff;
  #  title*0*=us-ascii'en'This%20is%20even%20more%20;
  #  title*1*=%2A%2A%2Afun%2A%2A%2A%20;
  #  title*2="isn't it!"
  my $ct = q(application/x-stuff;
   title*0*=us-ascii'en'This%20is%20even%20more%20;
   title*1*=%2A%2A%2Afun%2A%2A%2A%20;
   title*2="isn't it!");
  my $data = parse_content_type($ct);

  $data = {
    type       => "application",
    subtype    => "x-stuff",
    attributes => {
      title => "This is even more ***fun*** isn't it!"
    }
  };

  # Content-Disposition: attachment; filename=genome.jpeg;
  #   modification-date="Wed, 12 Feb 1997 16:29:51 -0500"
  my $cd = q(attachment; filename=genome.jpeg;
    modification-date="Wed, 12 Feb 1997 16:29:51 -0500");
  my $data = parse_content_disposition($cd);

  $data = {
    type       => "attachment",
    attributes => {
      filename            => "genome.jpeg",
      "modification-date" => "Wed, 12 Feb 1997 16:29:51 -0500"

FUNCTIONS

  parse_content_type
This routine is exported by default.

This routine parses email content type headers according to section 5.1 of RFC 2045 and also RFC 2231 (Character Set and Parameter Continuations). It returns a hash as above, with entries for the "type", the "subtype", and a hash of "attributes".

For backward compatibility with a really unfortunate misunderstanding of RFC 2045 by the early implementors of this module, "discrete" and "composite" are also present in the returned hashref, with the values of "type" and "subtype" respectively.

  parse_content_disposition
This routine is exported by default.

This routine parses email Content-Disposition headers according to RFC 2183 and RFC 2231. It returns a hash as above, with entries for the "type", and a hash of "attributes".

WARNINGS
This is not a valid content-type header, according to both RFC 1521 and RFC 2045:

  Content-Type: type/subtype;

If a semicolon appears, a parameter must. "parse_content_type" will carp if it encounters a header of this type, but you can suppress this by setting $Email::MIME::ContentType::STRICT_PARAMS to a false value. Please consider localizing this assignment!

Same applies for "parse_content_disposition".
