It also provides some convenience functions for constructing sections, e.g. showing the unread message count for each tag. This is done by specifying a list of functions that will be run when notmuch-hello is invoked. --- emacs/notmuch-hello.el | 624 ++++++++++++++++++++++++++++++++---------------- 1 files changed, 423 insertions(+), 201 deletions(-) diff --git a/emacs/notmuch-hello.el b/emacs/notmuch-hello.el index 65fde75..1f51281 100644 --- a/emacs/notmuch-hello.el +++ b/emacs/notmuch-hello.el @@ -70,11 +70,6 @@ should return a filter for that tag, or nil to hide the tag."
