From 84767fd5823b3b421be83000255951316e85be8c Mon Sep 17 00:00:00 2001 From: Jameson Rollins Date: Thu, 4 Feb 2010 07:07:26 -0500 Subject: [PATCH] notmuch.el: colorize lines in notmuch-search based on thread tags. Arbitrary font faces can be specified for given thread tags. By default, no coloring is applied. To specify coloring, place something like this in your .emacs: (setq notmuch-search-line-faces '(("delete" . '(:foreground "red")) ("unread" . '(:foreground "green")))) Order matters: line faces listed first will take precedence (in the example above, a thread tagged both "delete" and "unread" will be colored red, since the "delete" face is listed before the "unread"). notmuch.el | 33 ++++++++++++++++++++++++++++++++- 1 files changed, 32 insertions(+), 1 deletions(-) --- emacs/notmuch.el | 33 ++++++++++++++++++++++++++++++++- 1 file changed, 32 insertions(+), 1 deletion(-) diff --git a/emacs/notmuch.el b/emacs/notmuch.el index b32230e0..4bc42946 100644 --- a/emacs/notmuch.el +++ b/emacs/notmuch.el @@ -526,6 +526,35 @@ This function advances the next thread when finished." notmuch-search-target-line) (goto-line notmuch-search-target-line))))))) +(defcustom notmuch-search-line-faces nil + "Tag/face mapping for line highlighting in notmuch-search. + +Here is an example of how to color search results based on tags. +(the following text would be placed in your ~/.emacs file): + +(setq notmuch-search-line-faces '((\"delete\" .
