From: Alexander Botero-Lowry Date: Tue, 24 Nov 2009 07:39:57 +0000 (-0800) Subject: Make bodies locally toggleable X-Git-Tag: 0.1~337^2~1 X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=daeda152b8cdb662100129385212175b425c33c5;ds=sidebyside Make bodies locally toggleable Having actually implemented this, I realized that my initial approach of providing a function to configure a button was wrong. Instead I've replaced that with button types. This then makes it possible to provide the fully expanded view when all threads in a message are unread. It also has the potential to allow global-expansion functions if that is desireable --- diff --git a/notmuch.el b/notmuch.el index 23a07cca..af0c487e 100644 --- a/notmuch.el +++ b/notmuch.el @@ -497,12 +497,15 @@ which this thread was originally shown."
