NAME

Mail::Mbox::MessageParser::Grep - A GNU grep-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,

      'enable_grep' => 1,

    } );

  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 GNU grep-based mbox folder reader. It can only be used when GNU grep is installed on the system. Users must not instantiate this class directly---use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage the use of grep and non-grep implementations.

METHODS AND FUNCTIONS

The following methods and functions are specific to the Mail::Mbox::MessageParser::Grep 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 file_name parameter is the filename of the mailbox. The 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.
