NAME

Mail::Message::TransferEnc::QuotedPrint - handle quoted-printable message bodies

CLASS HIERARCHY

Mail::Message::TransferEnc::QuotedPrint
is a Mail::Message::TransferEnc
is a Mail::Reporter

SYNOPSIS

my Mail::Message $msg = ...;
my $decoded = $msg->decoded;
my $encoded = $msg->encode(transfer => 'quoted-printable');

DESCRIPTION

Encode and decode message bodies for quoted-printable transfer encoding. The Quoted-Printable encoding is intended to represent data that largely consists of bytes that correspond to printable characters in the ASCII character set. Non-printable characters (as defined by english americans) are represented by a triplet consisting of the character "=" followed by two hexadecimal digits.

METHOD INDEX

Methods prefixed with an abbreviation are described in Mail::Reporter (MR), Mail::Message::TransferEnc (MMT).

The general methods for Mail::Message::TransferEnc::QuotedPrint objects:

MMT check BODY [, OPTIONS]           MMT name
MMT create TYPE, OPTIONS                 new OPTIONS
    decode BODY                       MR report [LEVEL]
    encode                            MR reportAll [LEVEL]
 MR errors                            MR trace [LEVEL]
 MR log [LEVEL [,STRINGS]]            MR warnings

The extra methods for extension writers:

 MR AUTOLOAD                          MR inGlobalDestruction
 MR DESTROY                           MR logPriority LEVEL
MMT addTransferEncoder TYPE, CLASS    MR logSettings

METHODS

new OPTIONS

OPTION            DESCRIBED IN          DEFAULT
log               Mail::Reporter        'WARNINGS'
trace             Mail::Reporter        'WARNINGS'

decode BODY

Decoding is tricky, and not without loss of information. Lines will stay seperate lines, although they might have been joined before the encoding split them up. Characters which are not printable will be replaced by their octal value, and carriage returns ('=0D') at end of line are removed.

encode

Encoding is to quoted-printable is a careful process: All characters outside the normal printing range, and including '=' are encoded. They are translated into a '=' followed by a two digit hex of the ascii value of the character. The same treatment is for white-spaces at the end of a line.

The lines which are constructed which must be 76 characters max, not broken on encoded characters.
