README

NAME
    Email::FolderType - determine the type of a mail folder

SYNOPSIS
      use Email::FolderType qw(folder_type);

      print folder_type "~/mymbox";     # prints 'Mbox'
      print folder_type "~/a_maildir/"; # prints 'Maildir'
      print folder_type "some_mh/.";    # prints 'MH'
      print folder_type "an_archive//"; # prints 'Ezmlm'

DESCRIPTION
    Provides a utility subroutine for detecting the type of a given mail
    folder.

SUBROUTINES
  folder_type <path>
    Automatically detects what type of mail folder the path refers to and
    returns the name of that type.

    It primarily bases the type on the suffix of the path given.

      Suffix | Type
     --------+---------
      /      | Maildir
      /.     | MH
      //     | Ezmlm

    In case of no known suffix it checks for a known file structure. If that
    doesn't work out it defaults to "Mbox" although, if the "Mbox" matcher
    has been overridden or the default changed (see DEFAULT MATCHER below)
    then it will return undef.

  matchers
    Returns a list of all the matchers available to the system.

DEFAULT MATCHER
    Currently the default matcher is "Mbox" and therefore it is always
    checked last and always returns 1.

    If you really want to change this then you should override
    "Email::FolderType::Mbox::match" and/or change the variable
    $Email::FolderType::DEFAULT to be something other than 'Mbox'.

            use Email::FolderType;
            use Email::FolderType::Mbox;

            $Email::FolderType::DEFAULT = 'NewDefault';

        package Email::FolderType::Mbox;
        sub match { return (defined $_[0] && -f $_[0]) }

            package Email::FolderType::NewDefault;
            sub match { return (defined $_[0] && $_[0] =~ m!some crazy pattern!) }
            1;

REGISTERING NEW TYPES
    "Email::FolderType" briefly flirted with a rather clunky "register_type"
    method for registering new matchers but, in retrospect that wasn't a
    great idea.

    Instead, in this version we've reverted to a "Module::Pluggable" based
    system - any classes in the "Email::FolderType::" namespace will be
    interrogated to see if they have a c<match> method.

    If they do then it will be passed the folder name. If the folder matches
    then the match function should return 1. For example ...

        package Email::FolderType::GzippedMbox;

        sub match {
            my $folder = shift;
            return (-f $folder && $folder =~ /.gz$/);
        }

        1;

    These can even be defined inline ...

        #!perl -w

        use strict;
        use Email::Folder;
        use Email::LocalDelivery;

        # copy all mail from an IMAP folder
        my $folder = Email::Folder->new('imap://example.com'); # read INBOX
        for ($folder->messages) {
            Email::LocalDelivery->deliver($_->as_string, 'local_mbox');
        }

        package Email::FolderType::IMAP;

        sub match {
            my $folder = shift;
            return $folder =~ m!^imap://!;
        }

        1;

    If there is demand for a compatability shim for the old "register_type"
    method then we can implement one. Really though, this is much better in
    the long run.
