From 993dd5651a6c853bfe3870f6a69c7b329fa4e8ce Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 16 Jan 2018 11:46:03 +0100 Subject: curl: progress bar refresh, get width using ioctl() Get screen width from the environment variable COLUMNS first, if set. If not, use ioctl(). If nether works, assume 79. Closes #2242 The "refresh" is for the -# output when no total transfer size is known. It will now only use a single updated line even for this case: The "-=O=-" ship moves when data is transferred. The four flying "hashes" move (on a sine wave) on each refresh, independent of data. --- src/tool_cb_prg.c | 108 ++++++++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 89 insertions(+), 19 deletions(-) (limited to 'src/tool_cb_prg.c') diff --git a/src/tool_cb_prg.c b/src/tool_cb_prg.c index 8ea9ef020..dd8941631 100644 --- a/src/tool_cb_prg.c +++ b/src/tool_cb_prg.c @@ -5,7 +5,7 @@ * | (__| |_| | _ <| |___ * \___|\___/|_| \_\_____| * - * Copyright (C) 1998 - 2014, 2017, Daniel Stenberg, , et al. + * Copyright (C) 1998 - 2018, Daniel Stenberg, , et al. * * This software is licensed as described in the file COPYING, which * you should have received as part of this distribution.
