NAME

Net::IMAP::SimpleX - Addons for Net::IMAP::Simple

SYNOPSIS

use strict;
use warnings;
use Net::IMAP::SimpleX;

Net::IMAP::SimpleX uses Net::IMAP::Simple as a base so the object creation is the same as it is for the ancestor:

my $imap = Net::IMAP::SimpleX->new('imap.example.com') ||
   die "Unable to connect to IMAP: $Net::IMAP::Simple::errstr\n";

$imap->select("INBOX");

Net::IMAP::SimpleX is a collection of handy methods that are not simple, require Parse::RecDescent, or are experimental.

DESCRIPTION

This module adds some useful, yet not so simple, extensions on top of Net::IMAP::Simple.

METHODS

new

For details on the invocation, read Net::IMAP::Simple.

body_summary

Typical invocations will take this overall shape.

# get an object representation of the message body
my $summary = $imap->body_summary($message_number);

# multipart message
if ($summary->has_parts) {
    for my $subpart ($summary->parts) {
        if ($subpart->has_parts) { ... }
        # examine the message part
        my @attr = map { $subpart->$_ } qw/content_type encoding encoded_size/;
        # fetch the raw message part
        my $subpart_body = $imap->get($message_number, $subpart->part_number);
    }
} else {
    my $body = $summary->body;
    my @attr = map { $body->$_ } qw/content_type encoding encoded_size/
}

This method returns a simple object that contains a representation of the body of a message. The object is built by a Parse::RecDescent parser using the output of an IMAP fetch body command. The parser uses the formal syntax as defined by RFC3501 http://tools.ietf.org/html/rfc3501#section-9.

my $body = $summary->body;
my @attr = map { $body->$_ } qw/
    content_description
    encoded_size
    charset
    content_type
    part_number
    format
    id
    encoding
/;

For multipart messages, the object contains sub-objects for each message part, accessable via the parts() method and inspected via the has_parts() method. The type method describes the type of multipart (such as mixed or alternative). The parts method returns a list of sub parts, which themselves may have subparts, and so on.

An example of a multipart, alternative message with a text body and an html version of the body would looke something like:

if ($summary->has_parts) {
    if ($summary->type eq 'alternative') {
        my ($html) = grep { $_->content_type eq 'text/html' } $summary->parts;
    }
}

A really complex, multipart message could look something like this:

if ($summary->has_parts && $summary->type eq 'mixed') {

    for my $part ($summary->parts) {
        if ($part->has_parts && $part->type eq 'mixed') { ... }
        ...
    }

}

fetch

The fetch command returns the various parts of messages that users request. It is fairly complicated (following RFC3501 using a grammar/parser), but there are some basic patterns that it follows.

my $res  =$imap->fetch('30:32' => 'UID BODY.PEEK[HEADER.FIELDS (DATE)] FLAGS')
# $res = {
#   30 => {
#           "BODY[HEADER.FIELDS (DATE)]" => "Date: Sun, 18 Jul 2010 20:54:48 -0400\r\n\r\n",
#           "FLAGS" => ["\\Flagged", "\\Seen"],
#           "UID" => 58890,
#         },
#   31 => {
#           "BODY[HEADER.FIELDS (DATE)]" => "Date: Wed, 21 Jul 2010 09:09:04 -0400\r\n\r\n",
#           "FLAGS" => ["\\Seen"],
#           "UID" => 58891,
#         },
#   32 => {
#           "BODY[HEADER.FIELDS (DATE)]" => "Date: Sat, 24 Jul 2010 05:12:06 -0700\r\n\r\n",
#           "FLAGS" => ["\\Seen"],
#           "UID" => 58892,
#         },
# }

So-called "parenthized" lists will be returned as an array (see FLAGS) but nearly everything else will come back as strings. This includes parenthized queries. Take BODY.PEAK[HEADER.FIELDS (DATE FROM SUBJECT)]), for example. The result would come back as the RFC822 header lines (as the above Date: Sun, ... has done).

For more information about the different types of queries, see RFC3501. There's a surprising number of things that can be queried.
