From fedad1f30832e6b92ac87aaa39758758e783ceb7 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Fri, 25 Sep 2015 23:02:52 -0700 Subject: linenoise: no wasteful retrace on clear screen. * linenoise/linenoise.c (lino_clear_screen): Set l->maxrows to zero so that refresh_multiline won't emit useless upward cursor movement sequences. These have nowhere to go from the top line of the screen. --- linenoise/linenoise.c | 1 + 1 file changed, 1 insertion(+) (limited to 'linenoise') diff --git a/linenoise/linenoise.c b/linenoise/linenoise.c index a48ad4d1..e50eed2e 100644 --- a/linenoise/linenoise.c +++ b/linenoise/linenoise.c @@ -269,6 +269,7 @@ failed: /* Clear the screen.
