NAME

6       Mail::Message::Body::Construct - adds functionality to
7       Mail::Message::Body

SYNOPSIS

DESCRIPTION

11       This package adds complex functionality to the Mail::Message::Body
12       class.  This functions less often used, so many programs will not
13       compile this package.
14

METHODS

16   Constructing a body
17       $obj->attach($messages, %options)
18           Make a multipart containing this body and the specified $messages.
19           The options are passed to the constructor of the multi-part body.
20           If you need more control, create the multi-part body yourself.  At
21           least take a look at Mail::Message::Body::Multipart.
22
23           The message-parts will be coerced into a Mail::Message::Part, so
24           you may attach Mail::Internet or MIME::Entity objects if you want
25           --see Mail::Message::coerce().  A new body with attached messages
26           is returned.
27
28           example:
29
30            my $pgpkey = Mail::Message::Body::File->new(file => 'a.pgp');
31            my $msg    = Mail::Message->buildFromBody(
32               $message->decoded->attach($pgpkey));
33
34            # The last message of the $multi multiparted body becomes a coerced $entity.
35            my $entity  = MIME::Entity->new;
36            my $multi   = $msg->body->attach($entity);
37
38            # Now create a new message
39            my $msg     = Mail::Message->new(head => ..., body => $multi);
40
41       $obj->concatenate($components)
42           Concatenate a list of elements into one new body.
43
44           Specify a list of text $components.  Each component can be a
45           message (Mail::Message, the body of the message is used), a plain
46           body (Mail::Message::Body), "undef" (which will be skipped), a
47           scalar (which is split into lines), or an array of scalars (each
48           providing one line).
49
50           example:
51
52            # all arguments are Mail::Message::Body's.
53            my $sum = $body->concatenate($preamble, $body, $epilogue, "-- \n" , $sig);
54
55       $obj->foreachLine(CODE)
56           Create a new body by performing an action on each of its lines.  If
57           none of the lines change, the current body will be returned,
58           otherwise a new body is created of the same type as the current.
59
60           The CODE refers to a subroutine which is called, where $_ contains
61           body's original line.  DO NOT CHANGE $_!!!  The result of the
62           routine is taken as new line.  When the routine returns "undef",
63           the line will be skipped.
64
65           example:
66
67            my $content  = $msg->decoded;
68            my $reply    = $content->foreachLine( sub { '> '.$_ } );
69            my $rev      = $content->foreachLine( sub {reverse} );
70
71            sub filled() { length $_ > 1 ? $_ : undef }
72            my $nonempty = $content->foreachLine( \&filled );
73
74            my $wrong    = $content->foreachLine( sub {s/a/A/} );  # WRONG!!!
75            my $right    = $content->foreachLine(
76                   sub {(my $x=$_) =~ s/a/A/; $x} );
77
78       $obj->stripSignature(%options)
79           Strip the signature from the body.  The body must already be
80           decoded otherwise the wrong lines may get stripped.  Returned is
81           the stripped version body, and in list context also the signature,
82           encapsulated in its own body object.  The signature separator is
83           the first line of the returned signature body.
84
85           The signature is added by the sender to tell about him- or herself.
86           It is superfluous in some situations, for instance if you want to
87           create a reply to the person's message you do not need to include
88           that signature.
89
90           If the body had no signature, the original body object is returned,
91           and "undef" for the signature body.
92
93            -Option     --Default
94             max_lines    10
95             pattern      qr/^--\s?$/
96             result_type  <same as current>
97
98           max_lines => INTEGER|undef
99             The maximum number of lines which can be the length of a
100             signature.  Specify "undef" to remove the limit.
101
102           pattern => REGEX|STRING|CODE
103             Which pattern defines the line which indicates the separator
104             between the message and the signature.  In case of a STRING, this
105             is matched to the beginning of the line, and REGEX is a full
106             regular expression.
107
108             In case of CODE, each line (from last to front) is passed to the
109             specified subroutine as first argument.  The subroutine must
110             return TRUE when the separator is found.
111
112           result_type => CLASS
113             The type of body to be created for the stripped body (and maybe
114             also to contain the stripped signature)
115
116           example:
117
118            my $start = $message->decoded;
119            my $start = $body->decoded;
120
121            my $stripped = $start->stripSignature;
122
123            my ($stripped, $sign) = $start->stripSignature
124                (max_lines => 5, pattern => '-*-*-');
