Mail::Mbox::MessageParser::Perl - A Perl-based mbox folder reader
SYNOPSIS
#!/usr/bin/perl
use Mail::Mbox::MessageParser;
my $filename = 'mail/saved-mail';
my $filehandle = new FileHandle($filename);
my $folder_reader =
new Mail::Mbox::MessageParser( {
'file_name' => $filename,
'file_handle' => $filehandle,
} );
die $folder_reader unless ref $folder_reader;
# Any newlines or such before the start of the first email
my $prologue = $folder_reader->prologue;
print $prologue;
# This is the main loop. It's executed once for each email
while(!$folder_reader->end_of_file());
{
my $email = $folder_reader->read_next_email();
print $email;
}
DESCRIPTION
This module implements a Perl-based mbox folder reader. Users must not instantiate this class directly--use Mail::Mbox::MessageParser
instead. The base MessageParser module will automatically manage the use of faster implementations if they can be used.
METHODS AND FUNCTIONS
The following methods and functions are specific to the Mail::Mbox::MessageParser::Perl package. For additional inherited ones, see the
Mail::Mbox::MessageParser documentation.
$ref = new( { 'file_name' => <mailbox file name>, 'file_handle' => <mailbox file handle> });
<file_name> - The full filename of the mailbox
<file_handle> - An opened file handle for the mailbox
The constructor for the class takes two parameters. The optional file_name parameter is the filename of the mailbox. The required
file_handle argument is the opened file handle to the mailbox.
Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the error.
