From 389ddf0f123259b3a2cad24be2b356dd5219c49b Mon Sep 17 00:00:00 2001 From: Dmitry Kurochkin Date: Sun, 5 Feb 2012 11:13:45 +0400 Subject: [PATCH] emacs: make "+" and "-" tagging operations in notmuch-show more flexible Before the change, "+" and "-" tagging operations in notmuch-show view accepted only a single tag. The patch makes them use the recently added `notmuch-read-tag-changes' function, which allows to enter multiple tags with "+" and "-" prefixes. So after the change, "+" and "-" bindings in notmuch-show view allow to both add and remove multiple tags. The only difference between "+" and "-" is the minibuffer initial input ("+" and "-" respectively). --- emacs/notmuch-show.el | 73 +++++++++++++++---------------------------- 1 file changed, 26 insertions(+), 47 deletions(-) diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el index 7469e2eb..48a2a60f 100644 --- a/emacs/notmuch-show.el +++ b/emacs/notmuch-show.el @@ -38,9 +38,10 @@ (declare-function notmuch-call-notmuch-process "notmuch" (&rest args)) (declare-function notmuch-fontify-headers "notmuch" nil) -(declare-function notmuch-select-tag-with-completion "notmuch" (prompt &rest search-terms)) +(declare-function notmuch-read-tag-changes "notmuch" (&optional initial-input &rest search-terms)) (declare-function notmuch-search-next-thread "notmuch" nil) (declare-function notmuch-search-show-thread "notmuch" nil) +(declare-function notmuch-update-tags "notmuch" (current-tags tag-changes)) (defcustom notmuch-message-headers '("Subject" "To" "Cc" "Date") "Headers that should be shown in a message, in this order. @@ -1282,7 +1283,7 @@ Some useful entries are: (defun notmuch-show-mark-read () "Mark the current message as read." - (notmuch-show-remove-tag "unread")) + (notmuch-show-tag-message "-unread")) ;; Functions for getting attributes of several messages in the current ;; thread. @@ -1495,51 +1496,32 @@ than only the current message."
