From: Carl Worth Date: Tue, 27 Apr 2010 00:59:01 +0000 (-0700) Subject: emacs: Make update of notmuch-hello leave point on the same widget. X-Git-Tag: 0.3~32 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ddce8438a086fdc79d72f5b9fae364199d33c6bd;p=notmuch.git emacs: Make update of notmuch-hello leave point on the same widget. Before refreshing, we check which widget we are currently on, (or look for the next widget), and then we watch for that same widget to go by when constructing the buffer contents. Finally, we jump to the position we saw when the widget went by. --- diff --git a/emacs/notmuch-hello.el b/emacs/notmuch-hello.el index b4423edf..f68fdb5b 100644 --- a/emacs/notmuch-hello.el +++ b/emacs/notmuch-hello.el @@ -147,7 +147,7 @@ diagonal." notmuch-search-oldest-first nil nil #'notmuch-hello-search-continuation)) -(defun notmuch-hello-insert-tags (tag-alist widest) +(defun notmuch-hello-insert-tags (tag-alist widest target) (let* ((tags-per-line (max 1 (/ (- (window-width) notmuch-hello-indent) ;; Count is 7 wide, 1 for the space @@ -157,7 +157,8 @@ diagonal."
