From bc236109fd8b858f1bfd7e4b9c5d5e493bdd1563 Mon Sep 17 00:00:00 2001 From: Tiago Cunha Date: Sun, 11 Oct 2009 23:55:26 +0000 Subject: Sync OpenBSD patchset 374: Rather than running status-left, status-right and window title #() with popen immediately every redraw, queue them up and run them in the background, starting each once every status-interval. The actual status line uses the output from the last run. This brings several advantages: - tmux itself may be called from inside #() without causing the server to hang; - likewise, sleep or similar doesn't cause the server to block; - commands aren't run excessively often when redrawing; - commands shared by status-left and status-right, or used multiple times, will only be run once. run-shell and if-shell still use system()/popen() but will be changed over to use this too later. --- tmux.1 | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'tmux.1') diff --git a/tmux.1 b/tmux.1 index 5b609a0c..fb7d154d 100644 --- a/tmux.1 +++ b/tmux.1 @@ -1,4 +1,4 @@ -.\" $Id: tmux.1,v 1.184 2009-10-11 23:46:02 tcunha Exp $ +.\" $Id: tmux.1,v 1.185 2009-10-11 23:55:26 tcunha Exp $ .\" .\" Copyright (c) 2007 Nicholas Marriott .\" @@ -1437,6 +1437,11 @@ may contain any of the following special character sequences: The #(command) form executes .Ql command as a shell command and inserts the first line of its output. +Note that shell commands are only executed once at the interval specified by +the +.Ic status-interval +option: if the status line is redrawn in the meantime, the previous result is +used. #[attributes] allows a comma-separated list of attributes to be specified, these may be .Ql fg=colour -- cgit
