NAME

       Mail::Mbox::MessageParser::MetaInfo - A cache for folder metadata

DESCRIPTION

       This module implements a cache for meta-information for mbox folders. The information includes such items such as the file position, the
       line number, and the byte offset of the start of each email.

   METHODS AND FUNCTIONS
       SETUP_CACHE(...)
	     SETUP_CACHE( { 'file_name' => <cache file name> } );

	     <cache file name> - the file name of the cache

	   Call this function once to set up the cache before creating any parsers. You must provide the location to the cache file. There is no
	   default value.

	   Returns an error string or 1 if there is no error.

       CLEAR_CACHE();
	   Use this function to clear the cache and delete the cache file.  Normally you should not need to clear the cache--the module will
	   automatically update the cache when the mailbox changes. Call this function after SETUP_CACHE.

       WRITE_CACHE();
	   Use this function to force the module to write the in-memory cache information to the cache file. Normally you do not need to do
	   this--the module will automatically write the information when the program exits.

       $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. file_name is the filename of the mailbox. This will be used as the cache key, so
	   it's important that it fully defines the path to the mailbox. The file_handle argument is the opened file handle to the mailbox. Both
	   arguments are required.

	   Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the error.

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.
