From 8cee113819ffa678bbc4b0fa7a0040779a067682 Mon Sep 17 00:00:00 2001 From: David Edmondson Date: Mon, 12 Apr 2010 08:51:30 +0100 Subject: [PATCH] emacs: Support for customizing search result display This patch helps in customizing search result display similar to mutt's index_format. The customization is done by defining an alist as below: (setq notmuch-search-result-format '(("date" . "%s ") ("authors" . "%-40s ") ("subject" . "%s "))) The supported keywords are date, count, authors, subject and tags.
