[PATCH v2] nmbug-status: add support for specifying sort order for each view

Subject: [PATCH v2] nmbug-status: add support for specifying sort order for each view

Date: Sat, 26 Sep 2015 14:37:51 +0300

To: Tomi Ollila, W. Trevor King

Cc: notmuch@notmuchmail.org

From: Jani Nikula

Let each view have a "sort" key, typically used with values
"oldest-first" or "newest-first" (although all values in Query.SORT
are accepted), and sort the results accordingly. Oldest first remains
the default.

The dynamic approach of mapping sort values is as suggested by
W. Trevor King <wking@tremily.us>.
