Subject: [PATCH 10/11] lei_view_text: translate background colors from git
Date: Wed, 28 Apr 2021 07:52:04 +0000 [thread overview]
Message-ID: <20210428075205.19440-11-e@80x24.org> (raw)
In-Reply-To: <20210428075205.19440-1-e@80x24.org>
This seems to work with or without attributes. We'll deal with
256-color terminal colors when/if somebody cares for it, but the
usual 16 ought to be more than enough.
