NAME
       Email::MIME::ContentType - Parse and build a MIME Content-Type or Content-Disposition
       Header

VERSION
       version 1.026

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"
           }
         };

         my $ct_new = build_content_type($data);
         # text/plain; 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"
           }
         };

         my $cd_new = build_content_disposition($data);
         # attachment; 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".

   build_content_type
       This routine is exported by default.

       This routine builds email Content-Type header according to RFC 2045 and RFC 2231.  It
       takes a hash as above, with entries for the "type", the "subtype", and optionally also a
       hash of "attributes".  It returns a string representing Content-Type header.  Non-ASCII
       attributes are encoded to UTF-8 according to Character Set section of RFC 2231.  Attribute
       which has more then 78 ASCII characters is split into more attributes accorrding to
       Parameter Continuations of RFC 2231.  For compatibility reasons with clients which do not
       support RFC 2231, output string contains also truncated ASCII version of any too long or
       non-ASCII attribute.  Encoding to ASCII is done via Text::Unidecode module.

   build_content_disposition
       This routine is exported by default.

       This routine builds email Content-Disposition header according to RFC 2182 and RFC 2231.
       It takes a hash as above, with entries for the "type", and optionally also a hash of
       "attributes".  It returns a string representing Content-Disposition header.  Non-ASCII or
       too long attributes are handled in the same way like in build_content_type function.

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".
