NAME
Mail::Server::IMAP4::List - folder related IMAP4 answers

SYNOPSIS
 my $imap = Mail::Server::IMAP4::List->new
   ( folders   => $folders   # Mail::Box::Identity
   , inbox     => $inbox     # Mail::Box
   , delimiter => '#'
   );

 my $imap = Mail::Server::IMAP4::List->new(user => $user);
 print $imap->list(...);        # for LIST command

DESCRIPTION

METHODS

  Constructors

Mail::Server::IMAP4::List->new($user)
    Create a (temporary) object to handle the LIST requests for a certain user, based upon a set of folders. The data is kept by Mail::Box::Identity and Mail::Box::Collection objects, which mean that the folders will not be opened to answer these questions.

     -Option   --Default
      delimeter  '/'
      folders    <from user>
      inbox      <from user>
      user       <undef>

    delimeter => STRING|CODE
        Either the constant delimiter, or a code reference which will get passed a folder name and should return the delimiter string used in that name. If that folder name is empty, the default delimiter must be reported. See delimiter() for an example.

    folders => OBJECT
        You need to specify either a set of folders explicitly or via the user. Some Mail::Box::Identity OBJECT is needed.

    inbox => BOOLEAN
        For now, only used to see whether there is an inbox, so a truth value will do. This may change in the future. By default, the flag is set if "$user-"inbox> is defined.

    user => OBJECT
        A Mail::Box::Manage::User OBJECT, representing the user who's folders must get reported.

  Attributes

$obj->delimiter( [$foldername] )
    Returns the delimiter string. The foldername is only required when a CODE reference was specified at initiation.

    example: setting-up an IMAP4 delimeter

     sub delim($)
     {   my $path = shift;
         my ($delim, $root)
           = $path =~ m/^(#news\.)/ ? ('.', $1)
           = $path =~ m!^/!         ? ('/', '/')
           :                          ('/', '');

         wantarray ? ($delim, $root) : $delim;
     }

     my $list = Mail::Server::IMAP4::List->new(delimiter => \&delim, ...);
     print $list->delimiter('abc/xyz');      # returns a / (slash) and ''
     print $list->delimiter('#news.feed');   # returns a . (dot)   and $news.
     print $list->delimiter('');             # returns default delimiter

$obj->folders()
    Returns the Mail::Box::Identity of the toplevel folder.

$obj->inbox()
    Returns the Mail::Box or filename of the INBOX.

$obj->user()
    Returns the Mail::Box::Manage::User object, if defined.

  IMAP Commands

$obj->list($base, $pattern)
    IMAP's LIST command. The request must be partially decoded, the answer will need to be encoded.

    example: using IMAP list

     my $imap  = Mail::Server::IMAP4::List->new(delimiter => \&delim, ...);
     local $"  = ';';

     my @lines = $imap->list('', '');  # returns the default delimiter
     print ">@{$lines[0]}<";           #  >(\Noselect);/;<

     my @lines = $imap->list('#news',''); # specific delimiter
     print ">@{$lines[0]}<";           #  >(\Noselect);.;<

     my @lines = $imap->list('top/x/', '%');
     print ">@$_<," foreach @lines;    #  >();/;/tmp/x/y<,>(\Marked);/;/tmp/x/z<
