We currently allow the cursor to be positioned on the "End of search results" line after the last thread in a search buffer. When refreshing on this line, there's no thread ID to be used as the target. Previously, a refresh from this case would result in a nil thread target, but we were also using nil to indicate that the target thread had been found. This caused the position to be lost during refresh, (the cursor would move from the last line in the buffer to the first). We fix this by using a magic string of "found" rather than nil to clearly indicate whether the target thread has actually been found.

|
|
; 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
|
|
;
|
|

Reading the thread sequentially is well-supported by pressing

\\[notmuch-show-advance-and-archive]. 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).

removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread without

scrolling through with \\[notmuch-show-advance-and-archive]).

tag). The '\\[notmuch-search-operate-all]' key can be used to add or remove a tag from all
