+\r
+Is anyone else interested in Gmail-like "mute" support in notmuch.el?\r
+If so, I can think about polishing the below off and adding it to\r
+notmuch.\r
+\r
+I've managed to implement Gmail's "mute" in notmuch as follows in my\r
+notmuch-post-new:\r
+\r
+----------------------------------------------------------------------\r
+# Unmute all threads with new messages sent to me.\r
+notmuch search --output=threads tag:new AND tag:me | \\r
+ xargs --no-run-if-empty notmuch tag -muted --\r
+\r
+# Remove all muted threads from the inbox and mark every message in them\r
+# muted. Ideally this would be atomic with the above.\r
+notmuch search --output=threads tag:muted | \\r
+ xargs --no-run-if-empty notmuch tag -inbox +muted --\r
+----------------------------------------------------------------------\r
+\r
+Then in .emacs:\r
+\r
+----------------------------------------------------------------------\r
+(defcustom my-notmuch-mute-tags '("+muted" "-inbox")\r
+ "List of tag changes to apply to a message or a thread when it is muted.\r
+\r
+Tags starting with \"+\" (or not starting with either \"+\" or\r
+\"-\") in the list will be added, and tags starting with \"-\"\r
+will be removed from the message or thread being archived.\r
+\r
+For example, if you wanted to remove an \"inbox\" tag and add an\r
+\"archived\" tag, you would set:\r
+ (\"-inbox\" \"+archived\")"\r
+ :type '(repeat string)\r
+ :group 'notmuch-search\r
+ :group 'notmuch-show)\r
+\r
+;; TODO: consider defadvice?\r
+(defun my-notmuch-search-mute-thread (&optional unarchive beg end)\r
+ "Mute the currently selected thread or region.\r
+\r
+Mute each message in the currently selected thread by applying the\r
+tag changes in `my-notmuch-mute-tags' to each (remove the \"inbox\"\r
+tag by default). If a prefix argument is given, the messages will\r
+be \"unarchived\" (i.e. the tag changes in `my-notmuch-mute-tags'\r
+will be reversed).\r
+\r
+This function advances the next thread when finished."\r
+ (interactive (cons current-prefix-arg (notmuch-search-interactive-region)))\r
+ (let ((notmuch-archive-tags my-notmuch-mute-tags))\r
+ (notmuch-search-archive-thread unarchive beg end)))\r
+\r
+(defun my-notmuch-show-mute-thread-then-next ()\r
+ (interactive)\r
+ "Mute all messages in the current buffer, then show next thread from search."\r
+ (let ((notmuch-archive-tags my-notmuch-mute-tags))\r
+ (notmuch-show-archive-thread-then-next)))\r
+\r
+(define-key notmuch-search-mode-map "m" 'my-notmuch-search-mute-thread)\r
+(define-key notmuch-show-mode-map "m" 'my-notmuch-show-mute-thread-then-next)\r
+----------------------------------------------------------------------\r
