Package: vlc-nox
Version: 2.0.3-4
Even with TERM set to ‘dumb’, vlc(1) and cvlc(1) still try to
produce a colorful --help output (presumably using some
hardwired escape sequences) on a TTY.
This is particularly annoying when running from an
“application-embedded” Shell (such as Emacs' M-x shell, or
M-! ⟨command⟩ &), which typically employ a pseudo terminal.
Consider, e. g. (with ESC's replaced with ^['s):
$ echo "$TERM"
dumb
$ infocmp
# Reconstructed via infocmp from file: /lib/terminfo/d/dumb
dumb|80-column dumb tty,
am,
cols#80,
bel=^G, cr=^M, cud1=^J, ind=^J,
$ cvlc --help
VLC media player 2.0.3 Twoflower (revision 2.0.2-93-g77aa89e)
Usage: vlc [options] [stream] ...
…
^[[0;1mNo matching module found. Use --list or --list-verbose to list available
modules.^[[0m
^[[32;1m
Audio
^[[0m^[[0;1m --audio, --no-audio ^[[0m^[[34;1mEnable audio (default
enabled)
$
Naturally, such output should always respect terminfo(5) (or
termcap(5)) settings, and no attempt should be made to output
any “fancy” escape sequences that aren't mentioned there.
