notmuch/TODO

Fix the things that are causing the most pain to new users
----------------------------------------------------------
1. A new import is tagging all messages as "inbox" -- total pain

2. Allow an easy way to get tags from directory names (if the user has them)

3. Allow an easy way to remove excess tags, (date-based search)

4. Make emacs fast for big search results (see "lazy searching" below)

5. Fix Xapian defect #250 so tagging is fast.

Emacs interface (notmuch.el)
----------------------------
Make the keybindings help ('?') display the summary of each command's
documentation, not the function name.

Add a global keybinding table for notmuch, and then view-specific
tables that add to it.

Add a command to archive all threads in a search view.

Lazy searching: call "notmuch search" with --first and --max to fill
just a screenful of results, and then fill in more as ther user pages
through the buffer.

Add a '|' binding from the search view.

Add a binding to run a search from notmuch-show-mode.

When a thread has been entirely read, start out by closing all
messages except those that matched the search terms.

Add support for choosing from one of the user's configured email
addresses for the From line.

Make 'notmuch-show-pipe-message have a private history.

Add support for a delete keybinding that adds a "deleted" tag to the
current message/thread and make searches not return deleted messages
by default, (unless the user asks explicitly for deleted messags in
the search query).

Add support to "mute" a thread (add a "muted" tag and then don't
display threads in searches by default where any message of the thread
has the "muted" tag).

Portability
-----------
Fix configure script to test each compiler warning we want to use.

Implement strndup locally (or call talloc_strndup instead).

Implement getline locally, (look at gnulib).

Completion
----------
Fix bash completion to complete multiple search options (both --first
and *then* --max-threads), and also complete value for --sort=
(oldest-first or newest-first).

notmuch command-line tool
-------------------------
Teach "notmuch search" to return many different kinds of results. Some
ideas:

	notmuch search --for threads	# Default if no --for is given
	notmuch search --for messages
	notmuch search --for tags
	notmuch search --for addresses
	notmuch search --for terms

Add a "--format" option to "notmuch search", (something printf-like
for selecting what gets printed).

Add a "--count-only" (or so?) option to "notmuch search" for returning
the count of search results.

Give "notmuch restore" some progress indicator. Until we get the
Xapian bugs fixed that are making this operation slow, we really need
to let the user know that things are still moving.

Add a "-f <filename>" option to select an alternate configuration
file.

Fix notmuch.c to call add_timestamp/get_timestamp with path names
relative to the database path. (Otherwise, moving the database to a
new directory will result in notmuch creating new timestamp documents
and leaving stale ones behind.)

Ensure that "notmuch new" is sane if its first, giant indexing session
gets interrupted, (that is, ensure that any results indexed so far are
flushed).

Fix notmuch.c to use a DIR prefix for directory timestamps, (the idea
being that it can then add other non-directory timestamps such as for
noting how far back in the past mail has been indexed, and whether it
needs to re-tag messages based on a theoretical "auto-tags"
configuration file).

Make "notmuch new" notice when a mail directory has gone more than a
month without receiving new mail and use that to trigger the printing
of the note that the user might want to mark the directory read-only.

Also make "notmuch new" optionally able to just mark those month-old
directories read-only on its own. (Could conflict with low-volume
lists such as announce lists if they are setup to deliver to their own
maildirs.)

notmuch library
---------------
Add support for files that are moved or deleted (which obviously need
to be handled differently).

Actually compile and install a libnotmuch shared library.

Fix to use the *last* Message-ID header if multiple such headers are
encountered, (I noticed this is one thing that kept me from seeing the
same message-ID values as sup).

Add support for the user to specify custom headers to be indexed.

Add support for configuring "virtual tags" which are a tuple of
(tag-name, search-specification). The database is responsible for
ensuring that the virtual tag is always consistent.

General
-------
Audit everything for dealing with out-of-memory (and drop xutil.c).

Write a test suite.

Achieve 100% test coverage with the test suite.

Investigate why the notmuch database is slightly larger than the sup
database for the same corpus of email.
