Sebastian Spaeth 8866a89e3c python: Remove Messages().__len__
Messages.__len__() exhausted the iterator and list() inherently calls
len(), so we could not invoke list(msgs) without getting errors. Fix
this by implementing __nonzero__ but removing __len__ on Messages.

Use Query.count_messages() or len(list(msgs)) if you need to know the
number.

.. currentmodule:: notmuch
Welcome to :mod:`notmuch`'s documentation
===========================================
The :mod:`notmuch` module provides an interface to the `notmuch <http://notmuchmail.org>`_ functionality, directly interfacing to a shared notmuch library.
Within :mod:`notmuch`, the classes :class:`Database`, :class:`Query` provide most of the core functionality, returning :class:`Threads`, :class:`Messages` and :class:`Tags`.
.. moduleauthor:: Sebastian Spaeth <Sebastian@SSpaeth.de>
:License: This module is covered under the GNU GPL v3 (or later).
This page contains the main API overview of notmuch |release|.
Notmuch can be imported as::
import notmuch
or::
from notmuch import Query,Database
More information on specific topics can be found on the following pages:

.. automodule:: notmuch
:todo: Document nmlib,STATUS
:class:`notmuch.Database` -- The underlying notmuch database
---------------------------------------------------------------------
.. autoclass:: notmuch.Database([path=None[, create=False[, mode=MODE.READ_ONLY]]])
.. automethod:: create
.. automethod:: open(path, status=MODE.READ_ONLY)
.. automethod:: get_path

.. automethod:: add_message
.. automethod:: remove_message
.. automethod:: find_message
.. automethod:: get_all_tags
.. automethod:: create_query
.. note:: :meth:`create_query` was broken in release
0.1 and is fixed since 0.1.1.
.. attribute:: Database.MODE
Defines constants that are used as the mode in which to open a database.
MODE.READ_ONLY
Open the database in read-only mode
MODE.READ_WRITE
Open the database in read-write mode
.. autoattribute:: db_p
:class:`notmuch.Query` -- A search query
-------------------------------------------------
.. autoclass:: notmuch.Query
.. automethod:: create
.. attribute:: Query.SORT
Defines constants that are used as the mode in which to open a database.
SORT.OLDEST_FIRST
Sort by message date, oldest first.
SORT.NEWEST_FIRST
Sort by message date, newest first.
SORT.MESSAGE_ID
Sort by email message ID.
SORT.UNSORTED
Do not apply a special sort order (returns results in document id
order).
.. automethod:: set_sort
.. attribute:: sort
Instance attribute :attr:`sort` contains the sort order (see
:attr:`Query.SORT`) if explicitely specified via
:meth:`set_sort`. By default it is set to `None`.
.. automethod:: search_threads
.. automethod:: search_messages
.. automethod:: count_messages
:class:`Messages` -- A bunch of messages
----------------------------------------
.. autoclass:: Messages
.. automethod:: collect_tags
.. method:: __len__()
.. note:: :meth:`__len__` was removed in version 0.6 as it exhausted
the iterator and broke list(Messages()). Use the
:meth:`Query.count_messages` function or use
`len(list(msgs))`.
:class:`Message` -- A single message
----------------------------------------
.. autoclass:: Message
.. automethod:: get_message_id
.. automethod:: get_thread_id
.. automethod:: get_replies
.. automethod:: get_filename
.. automethod:: get_filenames
.. attribute:: FLAG
FLAG.MATCH
This flag is automatically set by a
Query.search_threads on those messages that match the
query. This allows us to distinguish matches from the rest
of the messages in that thread.
