NAME
Mail::Box::Search::Grep - select messages within a mail box like grep does
INHERITANCE
Mail::Box::Search::Grep
is a Mail::Box::Search
is a Mail::Reporter
SYNOPSIS
use Mail::Box::Manager;
my $mgr = Mail::Box::Manager->new;
my $folder = $mgr->open('Inbox');
my $filter = Mail::Box::Search::Grep->new
( label => 'selected'
, in => 'BODY', match => qr/abc?d*e/
);
my @msgs = $filter->search($folder);
my $filter = Mail::Box::Search::Grep->new
( field => 'To'
, match => $my_email
);
if($filter->search($message)) {...}
DESCRIPTION
Try to find some text strings in the header and footer of messages. Various ways to limit the search to
certain header fields, the whole header, only the body, the whole message, but even binary multiparts,
are provided for.
The name grep is derived from the UNIX tool grep, which means: "Get Regular Expression and Print".
Although you can search using regular expressions (the Perl way of them), you do not have to print those
as result.

deleted => BOOLEAN
deliver => undef|CODE|'DELETE'|LABEL|'PRINT'|REF-ARRAY
Store the details about where the match was found. The search may take much longer when this
feature is enabled.
When an ARRAY is specified it will contain a list of references to hashes. Each hash contains the
information of one match. A match in a header line will result in a line with fields "message",
"part", and "field", where the field is a Mail::Message::Field object. When the match is in the
body the hash will contain a "message", "part", "linenr", and "line".
In case of a CODE reference, that routine is called for each match. The first argument is this
search object and the second a reference to same hash as would be stored in the array.
The "PRINT" will call printMatchedHead() or printMatchedBody() when any matching header resp body
line was found. The output is minimized by not reprinting the message info on multiple matches in
the same message.
"DELETE" will flag the message to be deleted in case of a match. When a multipart's part is
matched, the whole message will be flagged for deletion.
field => undef|STRING|REGEX|CODE
Not valid in combination with "in" set to "BODY". The STRING is one full field name (case-
insensitive). Use a REGEX to select more than one header line to be scanned. CODE is a routine
which is called for each field in the header. The CODE is called with the header as first, and
the field as second argument. If the CODE returns true, the message is selected.
in => 'HEAD'|'BODY'|'MESSAGE'
label => STRING
limit => NUMBER
log => LEVEL
logical => 'REPLACE'|'AND'|'OR'|'NOT'|'AND NOT'|'OR NOT'
match => STRING|REGEX|CODE
The pattern to be search for can be a REGular EXpression, or a STRING. In both cases, the match
succeeds if it is found anywhere within the selected fields.
With a CODE reference, that function will be called each field or body-line. When the result is
true, the details are delivered. The call formats are
$code->($head, $field); # for HEAD searches
$code->($body, $linenr, $line); # for BODY searches
The $head resp $body are one message's head resp. body object. The $field is a header line which
matches. The $line and $linenr tell the matching line in the body.
Be warned that when you search in "MESSAGE" the code must accept both formats.

DIAGNOSTICS
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.
