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

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<
