From 2d15f5985930f493d6df7f58399639ae64057c4a Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Tue, 20 Jan 2009 19:35:03 +0000 Subject: Try to change the window title to match the command running it in. This is done by reading argv[0] from the process group leader of the group that owns the tty (tcgetpgrp()). This can't be done portably so some OS-dependent code is introduced (ugh); OpenBSD, FreeBSD and Linux are supported at the moment. A new window flag, automatic-rename, is available: if this is set to off, the window name is not changed. Specifying a name with the new-window, new-session or rename-window commands will automatically set this flag to off for the window in question. To disable it entirely set the option to off globally (setw -g automatic-rename off). --- osdep-openbsd.c | 63 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 osdep-openbsd.c (limited to 'osdep-openbsd.c') diff --git a/osdep-openbsd.c b/osdep-openbsd.c new file mode 100644 index 00000000..2a6a7d1d --- /dev/null +++ b/osdep-openbsd.c @@ -0,0 +1,63 @@ +/* $Id: osdep-openbsd.c,v 1.1 2009-01-20 19:35:03 nicm Exp $ */ + +/* + * Copyright (c) 2009 Nicholas Marriott + * + * Permission to use, copy, modify, and distribute this software for any + * purpose with or without fee is hereby granted, provided that the above + * copyright notice and this permission notice appear in all copies. + * + * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS.
