# Mail::Box::Manage::User - phpMan

## NAME
    [Mail::Box::Manage::User] - manage the folders of a user

## INHERITANCE
     [Mail::Box::Manage::User]
       is a [Mail::Box::Manager]
       is a [Mail::Reporter]

     [Mail::Box::Manage::User] is extended by
       [Mail::Server::IMAP4::User]

## SYNOPSIS
     use [Mail::Box::Manage::User];
     use [User::Identity];

     my $id      = [User::Identity]->new(...);
     my $user    = [Mail::Box::Manage::User]->new
       ( identity  => $id
       , folderdir => "$ENV{HOME}/Mail"
       , inbox     => $ENV{MAIL}
       );

     my $inbox   = $user->open($user->inbox);
     my $top     = $user->topfolder;

## DESCRIPTION
    Where the [Mail::Box::Manager] takes care of some set of open folder, this
    extension will add knowledge about some related person. At the same
    time, it will try to cache some information about that person's folder
    files.

        autodetect => TYPE|ARRAY-OF-TYPES
        collection_type => CLASS
          Subfolders grouped together.

        default_folder_type => NAME|CLASS
        delimiter => STRING
          The separator used in folder names. This doesn't need to be the
          same as your directory system is using.

        folder_types => NEW-TYPE | ARRAY-OF-NEW-TYPES
        folderdir => DIRECTORY

        identity => OBJECT
          The main difference between the [Mail::Box::Manager] and this class,
          is the concept of some person (or virtual person) who's files are
          being administered by this object. The OBJECT is an
          [User::Identity].

          The smallest identity that will do: "my $id =
          [User::Identity]->new('myname')"

        inbox => NAME
          The name of the user's inbox.

  Attributes
    Extends "Attributes" in [Mail::Box::Manager].

    $obj->identity()
        Returns a [User::Identity] object.

    $obj->inbox( [$name] )
        (Set and) get the $name of the mailbox which is considered the
        folder for incoming mail. In many protocols, this folder is handled
        separately. For instance in IMAP this is the only case-insensitive
        folder name.

  Manage existing folders
    Extends "Manage existing folders" in [Mail::Box::Manager].

  Manage folders
    $obj->create($name, %options)
        Creates a new folder with the specified name. An folder's
        administrative structure ([Mail::Box::Identity]) is returned, but the
        folder is not opened.

        In the accidental case that the folder already exists, a warning
        will be issued, and an empty list/undef returned.

        The %options are passed to [Mail::Box::create]() of your default
        folder type, except for the options intended for this method itself.

         -Option       --Default
          create_real    <true>
          create_supers  <false>
          deleted        <false>
          id_options     []

        create_real => BOOLEAN
          When this option is false, the pysical folder will not be created,
          but only the administration is updated.

        create_supers => BOOLEAN
          When you create a folder where upper hierarchy level are missing,
          they will be created as well.

        deleted => BOOLEAN
          The folder starts as deleted.

        id_options => ARRAY
          Values passed to the instantiated [Mail::Box::Identity]. That object
          is very picky about the initiation values it accepts.

    $obj->delete($name)
        Remove all signs from the folder on the file-system. Messages still
        in the folder will be removed. This method returns a true value when
        the folder has been removed or not found, so "false" means failure.

        It is also possible to delete a folder using "$folder->delete",
        which will call this method here. OPTIONS, which are used for some
        other folder types, will be ignored here: the user's index contains
        the required details.

         -Option   --Defined in        --Default
          recursive  [Mail::Box::Manager]  <folder's default>

        recursive => BOOLEAN

        example: how to delete a folder

         print "no xyz (anymore)\n" if $user->delete('xyz');

    $obj->folder($name)
        Returns the folder description, a [Mail::Box::Identity].

    $obj->folderCollection($name)
        Returns a pair: the folder collection ([Mail::Box::Collection]) and
        the base name of $name.

    $obj->rename($oldname, $newname, %options)
        Rename the folder with name $oldname to $newname. Both names are
        full pathnames.

         -Option       --Default
          create_supers  <false>

        create_supers => BOOLEAN
          When you rename a folder to a place where upper hierarchy levels
          are missing, they will get be defined, but with the deleted flag
          set.

    $obj->topfolder()
        Returns the top folder of the user's mailbox storage.

## DIAGNOSTICS
    Error: Cannot create $name: higher levels missing
        Unless you set create(create_supers), all higher level folders must
        exist before this new one can be created.

    Error: Cannot rename $name to $new: higher levels missing
        Unless you set create(create_supers), all higher level folders must
        exist before this new one can be created.

    Error: Folder $name is already open.
        You cannot ask the manager for a folder which is already open. In
        some older releases (before MailBox 2.049), this was permitted, but
        then behaviour changed, because many nasty side-effects are to be
        expected. For instance, an [Mail::Box::update]() on one folder handle
        would influence the second, probably unexpectedly.

    Error: Folder $name is not a [Mail::Box]; cannot add a message.
        The folder where the message should be appended to is an object
        which is not a folder type which extends [Mail::Box]. Probably, it is
        not a folder at all.

    Warning: Folder does not exist, failed opening $type folder $name.
        The folder does not exist and creating is not permitted (see
        open(create)) or did not succeed. When you do not have sufficient
        access rights to the folder (for instance wrong password for POP3),
        this warning will be produced as well.

        The manager tried to open a folder of the specified type. It may
        help to explicitly state the type of your folder with the "type"
        option. There will probably be another warning or error message
        which is related to this report and provides more details about its
        cause. You may also have a look at new(autodetect) and
        new(folder_types).

    Warning: Folder type $type is unknown, using autodetect.
        The specified folder type (see open(type), possibly derived from the
        folder name when specified as url) is not known to the manager. This
        may mean that you forgot to require the [Mail::Box] extension which
        implements this folder type, but probably it is a typo. Usually, the
        manager is able to figure-out which type to use by itself.

    Error: Illegal folder URL '$url'.
        The folder name was specified as URL, but not according to the
        syntax. See decodeFolderURL() for an description of the syntax.

    Error: No foldername specified to open.
        "open()" needs a folder name as first argument (before the list of
        options), or with the "folder" option within the list. If no name
        was found, the MAIL environment variable is checked. When even that
        does not result in a usable folder, then this error is produced. The
        error may be caused by an accidental odd-length option list.

    Error: Package $package does not implement $method.
        Fatal error: the specific package (or one of its superclasses) does
        not implement this method where it should. This message means that
        some other related classes do implement this method however the
        class at hand does not. Probably you should investigate this and
        probably inform the author of the package.

    Error: Unable to remove folder $dir
    Error: Use appendMessage() to add messages which are not in a folder.
        You do not need to copy this message into the folder, because you do
        not share the message between folders.

    Warning: Use moveMessage() or copyMessage() to move between open
    folders.
        The message is already part of a folder, and now it should be
        appended to a different folder. You need to decide between copy or
        move, which both will clone the message (not the body, because they
        are immutable).

    Warning: Will never create a folder $name without having write access.
        You have set open(create), but only want to read the folder. Create
        is only useful for folders which have write or append access modes
        (see [Mail::Box::new](access)).
