:mod:`mhlib` --- Access to MH mailboxes
=======================================

.. module:: mhlib
   :synopsis: Manipulate MH mailboxes from Python.
   :deprecated:

.. deprecated:: 2.6
    The :mod:`mhlib` module has been removed in Python 3. Use the
    :mod:`mailbox` instead.

.. sectionauthor:: Skip Montanaro <skip@pobox.com>

The :mod:`mhlib` module provides a Python interface to MH folders and their
contents.

The module contains three basic classes, :class:`MH`, which represents a
particular collection of folders, :class:`Folder`, which represents a single
folder, and :class:`Message`, which represents a single message.

.. class:: MH([path[, profile]])

:class:`MH` represents a collection of MH folders.

.. class:: Folder(mh, name)

The :class:`Folder` class represents a single folder and its messages.

.. class:: Message(folder, number[, name])

:class:`Message` objects represent individual messages in a folder.  The Message
   class is derived from :class:`mimetools.Message`.

.. _mh-objects:

MH Objects

:class:`MH` instances have the following methods:

.. method:: MH.error(format[, ...])

Print an error message -- can be overridden.

.. method:: MH.getprofile(key)

Return a profile entry (``None`` if not set).

.. method:: MH.getpath()

Return the mailbox pathname.

.. method:: MH.getcontext()

Return the current folder name.

.. method:: MH.setcontext(name)

Set the current folder name.

.. method:: MH.listfolders()

Return a list of top-level folders.

.. method:: MH.listallfolders()

Return a list of all folders.

.. method:: MH.listsubfolders(name)

Return a list of direct subfolders of the given folder.

.. method:: MH.listallsubfolders(name)

Return a list of all subfolders of the given folder.

.. method:: MH.makefolder(name)

Create a new folder.

.. method:: MH.deletefolder(name)

Delete a folder -- must have no subfolders.

.. method:: MH.openfolder(name)

Return a new open folder object.

.. _mh-folder-objects:

Folder Objects
--------------

:class:`Folder` instances represent open folders and have the following methods:

.. method:: Folder.error(format[, ...])

Print an error message -- can be overridden.

.. method:: Folder.getfullname()

Return the folder's full pathname.

.. method:: Folder.getsequencesfilename()

Return the full pathname of the folder's sequences file.

.. method:: Folder.getmessagefilename(n)

Return the full pathname of message *n* of the folder.

.. method:: Folder.listmessages()

Return a list of messages in the folder (as numbers).

.. method:: Folder.getcurrent()

Return the current message number.

.. method:: Folder.setcurrent(n)

Set the current message number to *n*.

.. method:: Folder.parsesequence(seq)

Parse msgs syntax into list of messages.

.. method:: Folder.getlast()

Get last message, or ``0`` if no messages are in the folder.

.. method:: Folder.setlast(n)

Set last message (internal use only).

.. method:: Folder.getsequences()

Return dictionary of sequences in folder.  The sequence names are used  as keys,
   and the values are the lists of message numbers in the sequences.

.. method:: Folder.putsequences(dict)

Return dictionary of sequences in folder name: list.

.. method:: Folder.removemessages(list)

Remove messages in list from folder.

.. method:: Folder.refilemessages(list, tofolder)

Move messages in list to other folder.

.. method:: Folder.movemessage(n, tofolder, ton)

Move one message to a given destination in another folder.

.. method:: Folder.copymessage(n, tofolder, ton)

Copy one message to a given destination in another folder.

.. _mh-message-objects:

Message Objects
---------------

The :class:`Message` class adds one method to those of
:class:`mimetools.Message`:

.. method:: Message.openmessage(n)

Return a new open message object (costs a file descriptor).
