From 5a3b42fb8c556397841b86c5fda1c4554dab253a Mon Sep 17 00:00:00 2001 From: David Bremner Date: Fri, 5 Jun 2015 08:16:17 +0200 Subject: [PATCH] cli/count: add --lastmod In the short term we need a way to get lastmod information e.g. for the test suite. In the long term we probably want to add lastmod information to at least the structured output for several other clients (e.g. show, search). --- doc/man1/notmuch-count.rst | 5 +++++ notmuch-count.c | 32 +++++++++++++++++++++++--------- test/T570-revision-tracking.sh | 12 ++++++++++++ 3 files changed, 40 insertions(+), 9 deletions(-) diff --git a/doc/man1/notmuch-count.rst b/doc/man1/notmuch-count.rst index ca78c18b..99de13a9 100644 --- a/doc/man1/notmuch-count.rst +++ b/doc/man1/notmuch-count.rst @@ -47,6 +47,11 @@ Supported options for **count** include (or threads) in the database will be output.
