Hi,
I followed your post on this link
http://groups.google.com/group/vim_use/browse_thread/thread/df79faca8997b995
and wonder, what is the t_vb that you set for the visual bell to work ?
the default t_vb=^[[?5h$<100/>^[[?5l
does not work for me.
I want just the visual bell.
my $TERM is gnome-256color, vim 7.2.330 and i am using gnome-terminal
2.30.1.
(visual bell does work in bash + gvim so it's very bizzare for me).
Do you have any advice for me ?
Thanks.
(Next time, please send your questions to the mailing list, so even when I'm
not there, anyone may try and give an answer).
For visual bell only (and no beep), I use
set visualbell
in the vimrc. It works for me. It should work in gvim for anyone, and in
Console Vim if your termcap and your $TERM (or 'term') are correctly set up.
In case of termcap problems, toggling the 'ttybuiltin' option may sometimes
(but not always) help.
As I don't use gnome-terminal, I don't know the correct t_vb value for it. In
KDE konsole I get ^[[?5h$<100/>^[[?5l and in the Linux console I get
^[[?5h^[[?5l$<200/> (where each of the four ^[ is an Esc character).
The problem is with gnome-terminal itself. I don't think the options
are exposed via any configuration dialogs, but using gconf-editor, you
can find:
/apps/metacity/general/visual_bell
and
/apps/metacity/general/visual_bell_type
I think that 'checking' the former should do the trick. I found the
'fullscreen' value for the latter to be a bit jarring. Changing it to
'frame_flash' looks better, IMO.
For both visual and audible bell, I use
set errorbells visualbell
if 1 " has arithmetic evaluation
let &t_vb = "\x07" . &t_vb
" 0x07, or Ctrl-G, is the ASCII "Bell" character;
" it is supposed to ring the terminal's bell.
endif
if has('autocmd') && has('gui')
au GUIEnter * let &t_vb = "\<C-G>\e|50f"
" where 50 is the flash time in milliseconds
endif
I used this portion of Tony's suggestion to get this working:
let &t_vb = "\x07"
You can probably protect it in a conditional like:
if $TERM =~? 'gnome'
let &t_vb = "\x07"
endif
I tested via:
perl -lwe 'print "\a"' ; sleep 1 ; vim +'set eb vb' +'nonsense'
which should cause two flashes, the first from Perl printing a BEL
character (kind of like a control group -- should work in most terminal
emulators that support visual bells), and the second from the error within Vim.
