INHERITANCEMail::Box::Search
is a Mail::Reporter
Mail::Box::Search is extended by
Mail::Box::Search::Grep
Mail::Box::Search::SpamAssassin
Mail::Server::IMAP4::Search
SYNOPSIS
use Mail::Box::Manager;
my $mgr = Mail::Box::Manager->new;
my $folder = $mgr->open('Inbox');
my $filter = Mail::Box::Search::[something]->new;
my @msgs = $filter->search($folder, ...);
if($filter->search($message)) {...}
DESCRIPTION
This "Mail::Box::Search" class is the base class for various message
scan algorithms. The selected messages can be labeled. Boolean
operations on messages are supported.
Currently implemented searches:
Mail::Box::Search::Grep
Match header or body against a regular expression in a UNIX "grep"
like fashion.
Mail::Box::Search::SpamAssassin
Try to detect spam, using Mail::SpamAssassin.
Mail::Box::Search::IMAP
Search an IMAP folder for special interface IMAP folders provide
for it. UNDER CONSTRUCTION till Mail::Transport::IMAP4 is
complete.
METHODS
Constructors
Mail::Box::Search->new(OPTIONS)
Create a filter.
Option --Defined in --Default
binaries <false>
decode <true>
delayed <true>
deleted <false>
deliver undef
in 'BODY'
label undef
limit 0
log Mail::Reporter 'WARNINGS'
logical 'REPLACE'
multiparts <true>
trace Mail::Reporter 'WARNINGS'
. binaries => BOOLEAN
Whether to include binary bodies in the search.
. decode => BOOLEAN
Decode the messages before the search takes place. Even plain
text messages can be encoded, for instance as
"quoted-printable", which may disturb the results. However,
decoding will slow-down the search.
. delayed => BOOLEAN
Include the delayed messages (which will be parsed) in the
search. If you set this to false, you may find fewer hits.
. deleted => BOOLEAN
In most cases, you will not be interested in results which are
found in messages flagged to be deleted. However, with this
option you can specify you want them to be searched too.
. deliver => undef|CODE|'DELETE'
The exact functionality of this parameter differs per search
method, so read the applicable man-page. In any case "undef"
means that details are not collected for this search, which is
the fastest search.
"DELETE" will flag the message to be flagged for deletion. You
may also specify your own CODE reference. With an reference to
an array, the information about the matches is collected as a
list of hashes, one hash per match.
. in => 'HEAD'|'BODY'|'MESSAGE'
Where to look for the match.
. label => STRING
Mark all selected messages with the specified STRING. If this
field is not specified, the message will not get a label;
search() also returns a list of selected messages.
. limit => NUMBER
Limit the search to the specified NUMBER of messages. When the
NUMBER is positive, the search starts at the first message in
the folder or thread. A negative NUMBER starts at the end of
the folder. If the limit is set to zero, there is no limit.
. log => LEVEL
. logical => 'REPLACE'|'AND'|'OR'|'NOT'|'AND NOT'|'OR NOT'
Only applicable in combination with a "label". How to handle
the existing labels. In case of "REPLACE", messages which
already are carrying the label are stripped from their
selection (unless they match again). With "AND", the message
must be selected by this search and already carry the label,
otherwise the label will not be set. Specify "OR" to have
newly selected messages added to the set of already selected
messages.
"NOT" is true for messages which do not fulfil the search. The
details output will still contain the places where the match
was found, however those messages will complementary set of
messages will be labeled and returned.
. multiparts => BOOLEAN
Are multiparts to be included in the search results? Some MUA
have problems handling details received from the search. When
this flag is turned off, the body of multiparts will be
ignored. The parts search will include the preamble and
epilogue.
. trace => LEVEL
Searching
$obj->inBody(PART, BODY)
Tests whether body contains the requesting information. See the
specific search module for its parameters.
$obj->inHead(PART, HEAD)
Tests whether header contains the requesting information. See the
specific search module for its parameters.
$obj->search(FOLDER|THREAD|MESSAGE|ARRAY-OF-MESSAGES)
Check which messages from the FOLDER (Mail::Box) match the search
parameters. The matched messages are returned as list. You can
also specify a THREAD (a Mail::Box::Thread::Node), one single
MESSAGE (a Mail::Message), or an array of messages.
Sometimes we know how only one match is needed. In this case, this
searching will stop at the first match. For instance, when "limit"
is "-1" or 1, or when the search in done in scalar context.
example:
my $grep = Mail::Box::Search::Grep->new
( match => 'My Name Is Nobody'
, deliver => 'PRINT'
);
$grep->search($folder);
my $message = $folder->message(3);
$grep->search($message);
my $thread = $message->threadStart;
$grep->search($thread);
$obj->searchPart(PART)
Search this message PART for matches.
The Results
$obj->printMatch([FILEHANDLE], HASH)
Print the information about the match (see new(deliver)) in some
understandable way. If no file handle is specified, the output
will go to the selected filehandle (see "perldoc -f select").

DIAGNOSTICS
Error: Cannot search in body.
Th search object does not implement inBody(), and can therefore not
search a message body.
Error: Cannot search in header.
Th search object does not implement inHead(), and can therefore not
search a message header.
Error: Don't know how to deliver via results in $way.
The search results cannot be delivered in the specific way, because
that is not a defined alternative.
Error: Package $package does not implement $method.
Fatal error: the specific package (or one of its superclasses) does
not implement this method where it should. This message means that
some other related classes do implement this method however the
class at hand does not. Probably you should investigate this and
probably inform the author of the package.
Error: Search in BODY, HEAD or MESSAGE not $in.
The "in" option defines only three names.
