From 52f751fb7442d7fd79e2a7dae5858f23e28e4438 Mon Sep 17 00:00:00 2001 From: Dmitry Kurochkin Date: Thu, 26 May 2011 02:10:16 +0400 Subject: [PATCH] Simplify message and headers visibility code in notmuch-show view. Before the change, headers and message visibility functions took extra care to correctly set `buffer-invisibility-spec'. This was needed because headers overlay `invisible' property had only headers' invisibility spec. So visibility of headers was determined only by the headers invisibility spec. The patch sets headers overlay `invisible' property a list with both the headers and the message invisibility spec. This makes headers invisible if either of them is added to the `buffer-invisibility-spec' and allows to simplify the code. --- emacs/notmuch-show.el | 18 +++++------------- 1 file changed, 5 insertions(+), 13 deletions(-) diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el index a49bbd3d..0d9b52a7 100644 --- a/emacs/notmuch-show.el +++ b/emacs/notmuch-show.el @@ -753,8 +753,9 @@ current buffer, if possible." ;; message.
