=head1 NAME

Mail::Box::Manager - manage a set of folders

=head1 INHERITANCE

Mail::Box::Manager
   is a Mail::Reporter

Mail::Box::Manager is extended by
   Mail::Box::Manage::User

=head1 SYNOPSIS

use Mail::Box::Manager;
 my $mgr     = new Mail::Box::Manager;

# Create folder objects.
 my $folder   = $mgr->open(folder => $ENV{MAIL});
 my $message1 = $folder->message(0);
 $mgr->copyMessage('Draft', $message);

my @messages = $folder->message(0,3);
 $mgr->moveMessage('Outbox', @messages, create => 1 );
 $mgr->close($folder);

# Create thread-detectors (see Mail::Box::Thread::Manager)
 my $t       = $mgr->threads($inbox, $outbox);

my $threads = $mgr->threads(folder => $folder);
 foreach my $thread ($threads->all)
 {   $thread->print;
 }

$mgr->registerType(mbox => 'Mail::Box::MyType');

=head1 DESCRIPTION

The manager keeps track on a set of open folders and a set of message-thread
supporting objects.  You are not obliged to use this object (you can
directly create a L<Mail::Box::Mbox|Mail::Box::Mbox> if you prefer), but you will create
more portable and safer code if you do use it.

-Option             --Defined in     --Default
  autodetect                            undef
  default_folder_type                   'mbox'
  folder_types                          <all standard types>

  trace                Mail::Reporter   'WARNINGS'

=over 2

=item autodetect => TYPE|ARRAY-OF-TYPES

Select only a subset of the folder types which are implemented by MailBox
to be detected automatically.  This may improve the auto-detection of
folder types.  Normally, all folder types will be tried when a folder's
name is incorrect, but this option limits the types which are checked
and therefore may respond faster.

=item default_folder_type => NAME|CLASS

Specifies the default folder type for newly created folders.  If this
option is not specified, the most recently registered type is used (see
L<registerType()|Mail::Box::Manager/"Attributes"> and the L<new(folder_types)|Mail::Box::Manager/"METHODS"> option.

=item folder_types => NEW-TYPE | ARRAY-OF-NEW-TYPES

Add one or more new folder types to the list of known types.  The order is
important: when you open a file without specifying its type, the
manager will start trying the last added list of types, in order.

Each TYPE is specified as an array which contains name, class, and
defaults for options which overrule the usual defaults.  You may specify
folder-specific defaults as OPTIONS.  They override the settings of
the manager.

=item folderdir => DIRECTORY

The default directory, or directories, where folders are
located. The C<Mail::Box::Manager> can autodetect the existing folder-types.
There may be different kinds of folders opened at the same time, and
messages can be moved between those types, although that may result in
a loss of information depending on the folder types.

=item folderdirs => [DIRECTORIES]

=item log => LEVEL

=item trace => LEVEL

=back

=head2 Attributes

=over 4

=item $obj-E<gt>B<defaultFolderType>()

Returns the default folder type, some class name.

=item $obj-E<gt>B<folderTypes>()

Returns the list of currently defined folder types.

example:

print join("\n", $manager->folderTypes), "\n";

=item $obj-E<gt>B<folderdir>()

In list context, this returns all folderdirs specified.  In SCALAR
context only the first.

=item $obj-E<gt>B<registerType>($type, $class, %options)

With C<registerType> you can register one $type of folders.  The $class
is compiled automatically, so you do not need to C<use> them in your own
modules.  The $type is just an arbitrary name.

The added types are prepended to the list of known types, so they are
checked first when a folder is opened in autodetect mode.

example:

$manager->registerType(mbox => 'Mail::Box::Mbox',
     save_on_exit => 0, folderdir => '/tmp');

=back

=head2 Manage open folders

=over 4

=item $obj-E<gt>B<close>($folder, %options)

C<close> removes the specified folder from the list of open folders.
Indirectly it will update the files on disk if needed (depends on
the L<Mail::Box::new(save_on_exit)|Mail::Box/"Constructors"> flag for each folder). %options are
passed to L<Mail::Box::close()|Mail::Box/"The folder"> of the folder.

The folder's messages will also be withdrawn from the known message threads.
You may also close the folder directly. The manager will be informed
about this event and take appropriate actions.

-Option       --Default
  close_by_self  <false>

=over 2

=item close_by_self => BOOLEAN

Used internally to avoid confusion about how the close was started.  Do
not change this.

=back

example:

my $inbox = $mgr->open('inbox');
 $mgr->close($inbox);
 $inbox->close;        # alternative

=item $obj-E<gt>B<closeAllFolders>(, %options)

C<closeAllFolders> calls close() for each folder managed by
this object.  It is called just before the program stops (before global
cleanup).

=item $obj-E<gt>B<isOpenFolder>($folder)

Returns true if the $folder is currently open.

example:

print "Yes\n" if $mgr->isOpenFolder('Inbox');

=item $obj-E<gt>B<open>( [$foldername], %options )

Open a folder which name is specified as first parameter or with
the option flag C<folder>.  The folder type is autodetected unless
the C<type> is specified.

C<open> carries options for the manager which are described here, but
may also have additional options for the folder type.  For a
description of the folder options, see the options to the constructor
L<Mail::Box::new()|Mail::Box/"Constructors"> for each type of mail box.

-Option      --Default
  authenticate  'AUTO'
  create        <false>
  folder        $ENV{MAIL}
  folderdir     '.'
  type          <first, usually C<mbox>>

=over 2

=item authenticate => TYPE|ARRAY-OF-TYPES|'AUTO'

The TYPE of authentication to be used, or a list of TYPES which the
client prefers.  The server may provide preferences as well, and that
order will be kept.  This option is only supported by a small subset of
folder types, especially by POP and IMAP.

=item create => BOOLEAN

Create the folder if it does not exist. By default, this is not done.
The C<type> option specifies which type of folder is created.

=item folder => NAME|URL

Which folder to open, specified by NAME or special URL.
The URL format is composed as

type://username:password@hostname:port/foldername

Like real URLs, all fields are optional and have smart defaults, as long
as the string starts with a known folder type.  Far
from all folder types support all these options, but at least they are
always split-out.  Be warned that special characters in the password should
be properly url-encoded.

When you specify anything which does not match the URL format, it is
passed directly to the C<new> method of the folder which is opened.

=item folderdir => DIRECTORY

The directory where the folders are usually stored.

=item type => FOLDERTYPENAME|FOLDERTYPE

Specify the type of the folder.  If you do not specify this option while
opening a folder for reading, the manager checks all registered folder
types in order for the ability to open the folder. If you open a new
folder for writing, then the default will be the most recently registered
type. (If you add more than one type at once, the first of the list is
used.)

Currently, the types are C<mbox>, C<mh>, C<maildir>, C<pop3>, C<pop3s>,
C<imap4>, and C<imap4s>.  You may also use names C<pop>, C<pops>, C<imap>,
and C<imaps>.

=back

example: opening folders via the manager

my $jack  = $manager->open(folder => '=jack',
    type => 'mbox');

my $rcvd  = $manager->open('myMail',
    type => 'Mail::Box::Mbox', access => 'rw');

my $inbox = $manager->open('Inbox')
    or die "Cannot open Inbox.\n";

my $pop   = 'pop3://myself:secret@pop3.server.com:120/x';
 my $send  = $manager->open($url);

my $send  = $manager->open(folder => '/x',
   type => 'pop3', username => 'myself', password => 'secret'
   server_name => 'pop3.server.com', server_port => '120');

=item $obj-E<gt>B<openFolders>()

Returns a list of all open folders.

=back

=head2 Manage existing folders

=over 4

=item $obj-E<gt>B<delete>($foldername, %options)

Remove the named folder.  The %options are the same as those for L<open()|Mail::Box::Manager/"Manage open folders">.

The deletion of a folder can take some time.  Dependent on the type of
folder, the folder must be read first.  For some folder-types this will
be fast.

-Option   --Default
  recursive  <folder's default>

=over 2

=item recursive => BOOLEAN

Some folder can only be recursively deleted, other have more flexibility.

=back

=head2 Move messages to folders

=over 4

=item $obj-E<gt>B<appendMessage>( [$folder|$foldername], $messages, %options )

Append one or more messages to a folder (therefore, an C<appendMessages()>
is defined as well). You may specify a $foldername or an opened folder
as the first argument. When the name is that of an open folder, it is
treated as if the folder-object was specified, and not directly access
the folder-files.  You may also specify the foldername as part of the
options list.

If a message is added to an already opened folder, it is only added to
the structure internally in the program.  The data will not be written to
disk until a write of that folder takes place.  When the name of an
unopened folder is given, the folder is opened, the messages stored on
disk, and then the folder is closed.

A message must be an instance of a L<Mail::Message|Mail::Message>.  The actual message
type does not have to match the folder type--the folder will try to
resolve the differences with minimal loss of information.  The coerced
messages (how the were actually written) are returned as list.

The %options is a list of key/values, which are added to (overriding)
the default options for the detected folder type.

example:

$mgr->appendMessage('=send', $message, folderdir => '/');
 $mgr->appendMessage($received, $inbox->messages);

my @appended = $mgr->appendMessages($inbox->messages,
    folder => 'Drafts');
 $_->label(seen => 1) foreach @appended;

=item $obj-E<gt>B<copyMessage>( [$folder|$foldername], $messages, %options )

Copy a message from one folder into another folder.  If the destination
folder is already opened, L<Mail::Box::copyTo()|Mail::Box/"The folder"> is used.  Otherwise,
L<Mail::Box::appendMessages()|Mail::Box/"The folder"> is called.

You need to specify a folder's name or folder object as the first
argument, or in the options list.  The options are the same as those
which can be specified when opening a folder.

-Option--Default
  share   <false>

=over 2

=item share => BOOLEAN

Try to share the physical storage of the messages.  The folder types
may be different, but it all depends on the actual folder where the
message is copied to.  Silently ignored when not possible to share.

=back

example:

my $drafts = $mgr->open(folder => 'Drafts');
 my $outbox = $mgr->open(folder => 'Outbox');
 $mgr->copyMessage($outbox, $drafts->message(0));

my @messages = $drafts->message(1,2);
 $mgr->copyMessage('=Trash', @messages,
    folderdir => '/tmp', create => 1);

$mgr->copyMessage($drafts->message(1),
    folder => '=Drafts' folderdir => '/tmp',
    create => 1);

=item $obj-E<gt>B<moveMessage>( [$folder|$foldername], $messages, %options )

Move a message from one folder to another.

BE WARNED that removals from a folder only take place when the folder
is closed, so the message is only flagged to be deleted in the opened
source folder.

BE WARNED that message labels may get lost when a message is moved from
one folder type to an other.  An attempt is made to translate labels,
but there are many differences in interpretation by applications.

$mgr->moveMessage($received, $inbox->message(1))

is equivalent to

$mgr->copyMessage($received, $inbox->message(1), share => 1);
 $inbox->message(1)->delete;

-Option--Default
  share   <true>

=over 2

=item share => BOOLEAN

=back

=head2 Manage message threads

=over 4

=item $obj-E<gt>B<threads>( [$folders], %options )

Create a new object which keeps track of message threads.  You can
read about the possible options in L<Mail::Box::Thread::Manager|Mail::Box::Thread::Manager>.
As %options specify one folder or an array of $folders.
It is also permitted to specify folders before the options.

example:

my $t1 = $mgr->threads(folders => [ $inbox, $send ]);
 my $t2 = $mgr->threads($inbox);
 my $t3 = $mgr->threads($inbox, $send);

=back

=head2 Internals

=over 4

=item $obj-E<gt>B<decodeFolderURL>($url)

Try to decompose a folder name which is specified as $url (see open())
into separate options.  Special characters like @-sign, colon, and slash
used in the user or password parts must be passed $url-encoded.

=item $obj-E<gt>B<toBeThreaded>($folder, $messages)

Signal to the manager that all thread managers which are using the
specified folder must be informed that new messages are
coming in.

=item $obj-E<gt>B<toBeUnthreaded>($folder, $messages)

Signal to the manager that all thread managers which are using the
specified folder must be informed that new messages are
or going out.
