|
|
; This is an emacs-based interface to the notmuch mail system.
|
|
;
|
|
; You will first need to have the notmuch program installed and have a
|
|
; notmuch database built in order to use this. See
|
|
; http://notmuchmail.org for details.
|
|
;
|
|
; To install this software, copy it to a directory that is on the
|
|
; `load-path' variable within emacs (a good candidate is
|
|
; /usr/local/share/emacs/site-lisp). If you are viewing this from the
|
|
; notmuch source distribution then you can simply run:
|
|
;
|
|
; sudo make install-emacs
|
|
;
|
|
; to install it.
|
|
;
|
|
; Then, to actually run it, add:
|
|
;
|
|
; (require 'notmuch)
|
|
;
|
|
; to your ~/.emacs file, and then run "M-x notmuch" from within emacs,
|
|
; or run:
|
|
;
|
|
; emacs -f notmuch
|
|
;
|
|
; Have fun, and let us know if you have any comment, questions, or
|
|
; kudos: Notmuch list <notmuch@notmuchmail.org> (subscription is not
|
|
; required, but is available from http://notmuchmail.org).

This buffer contains the results of the \"notmuch show\" command
|
|
for displaying a single thread of email from your email archives.
|
|
|
|
By default, various components of email messages, (citations,
|
|
signatures, already-read messages), are hidden. You can make
|
|
these parts visible by clicking with the mouse button or by
|
|
pressing RET after positioning the cursor on a hidden part, (for
|
|
which \\[notmuch-show-next-button] and \\[notmuch-show-previous-button] are helpful).
|
|
|
|
Reading the thread sequentially is well-supported by pressing
|
|
\\[notmuch-show-advance-marking-read-and-archiving]. This will scroll the current message (if necessary),
|
|
advance to the next message, or advance to the next thread (if
|
|
already on the last message of a thread). As each message is
|
|
scrolled away its \"unread\" tag will be removed, and as each
|
|
thread is scrolled away the \"inbox\" tag will be removed from
|
|
each message in the thread.
|
|
|
|
Other commands are available to read or manipulate the thread more
|
|
selectively, (such as '\\[notmuch-show-next-message]' and '\\[notmuch-show-previous-message]' to advance to messages without
|
|
removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread without
|
|
scrolling through with \\[notmuch-show-advance-marking-read-and-archiving]).
|
|
|
|
You can add or remove arbitary tags from the current message with
|
|
'\\[notmuch-show-add-tag]' or '\\[notmuch-show-remove-tag]'.
|
|
|
|
All currently available key bindings:

This buffer contains a list of message counts returned by a
|
|
customizable set of searches of your email archives. Each line in
|
|
the buffer shows the name of a saved search and the resulting
|
|
message count.
|
|
|
|
Pressing RET on any line opens a search window containing the
|
|
results for the saved search on that line.
|
|
|
|
Here is an example of how the search list could be
|
|
customized, (the following text would be placed in your ~/.emacs
|
|
file):
|
|
|
|
(setq notmuch-folders '((\"inbox\" . \"tag:inbox\")
|
|
(\"unread\" . \"tag:inbox AND tag:unread\")
|
|
(\"notmuch\" . \"tag:inbox AND to:notmuchmail.org\")))
|
|
|
|
Of course, you can have any number of folders, each configured
|
|
with any supported search terms (see \"notmuch help search-terms\").
