Subject: notmuch.el: Add face support to search mode
X-Git-Tag: 0.1~297
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=92c4dcc641e9dfb5f65026ebae5cedc8eb1d9e21

notmuch.el: Add face support to search mode

This patch use notmuch-tag-face showing tags in the notmuch-search-mode.

We can selectively highlight each tag by setting notmuch-tag-face-alist as below

(defface notmuch-tag-unread-face
 '((((class color)) (:foreground "goldenrod")))
  "Notmuch search mode face used to highligh tags.")

(defface notmuch-tag-inbox-face
 '((((class color)) (:foreground "red")))
  "Notmuch search mode face used to highligh tags.")

(setq notmuch-tag-face-alist '(("unread" . 'notmuch-tag-unread-face)
			       ("inbox" . 'notmuch-tag-inbox-face)))
(require 'notmuch)
