NAME
Mail::Thread::Chronological - rearrange Mail::Thread::Containers into a Chronological structure
SYNOPSIS
use Mail::Thread;
use Mail::Thread::Chronological;
my $threader = Mail::Thread->new( @messages );
my $lurker = Mail::Thread::Chronological->new;
$threader->thread;
for my $thread ($threader->rootset) {
for my $row ( $lurker->arrange( $thread ) ) {
my $container = grep { ref $_ } @$row;
print join('', map { ref $_ ? '*' : $_ } @$row),
" ", $container->messageid, "\n";
}
}DESCRIPTION
Given a Mail::Thread::Container, Mail::Thread::Chronological transforms the tree structure into a 2-dimensional array representing the history of a given thread in time.
The output is similar to that of the Lurker mail archiving system, with a couple of small exceptions:
- Characters used
-
The grid is populated with the characters ' ' (space), '-', '+', '|', '{', or Mail::Thread::Container objects. Lurker uses [a-g], and differentiates T-junctions from corners for you, this module assumes you will do that for yourself.
The characters mean:
- Vertical stream crossing is permitted
-
In the original lurker crossing a path vertically is not allowed, this results in a lot of horizontal space being used.
METHODS
new
your common or garden constructor
arrange
Returns an array of arrays representing the thread tree.
extract_time( $container )
Extracts the time from a Mail::Thread::Container, returned as epoch seconds used to decide the order of adding messages to the rows.
