Description Ronald Cole 2000-01-14 19:18:59 EST
[ronald@yakisoba ronald]$ TERM=xterm vi
c[ronald@yakisoba ronald]$
^ this is the undesirable cookie

[ronald@yakisoba ronald]$ TERM=vt100 vi
[ronald@yakisoba ronald]$
^ no cookie, as I would expect

This is probably a terminfo bug, but there is no "terminfo" component
to select.

This doesn't happen on RH6.0.  Really annoying to look at.  My productivity
has been lower since...  ;)
Comment 1 Bernhard Rosenkraenzer 2000-01-18 05:10:59 EST
Doesn't happen to me on a current 6.2 snapshot...
Which terminal are you using? xterm, konsole, gnome-terminal, rxvt, ..... ?
Comment 2 Ronald Cole 2000-01-18 15:16:59 EST
Comment 3 Bill Nottingham 2000-02-05 15:38:59 EST
Only happens with /bin/vi, not vim.
Comment 4 khp 2000-03-03 20:13:59 EST
This happens to me with /usr/bin/vim on three 6.1 systems:
VIM - Vi IMproved 5.4 (1999 Jul 25, compiled Jul 27 1999 18:08:35)
but not with gvim. Note that the annoying "c" character is put out upon entering
vim, not when exiting. I'm using gnome-terminal.
Comment 5 Luca Bonomi 2000-03-30 09:49:59 EST
This happens to me since 6.1 and also in 6.2 using 'konsole'.
Not seen if I use kvt or xterm.

Comment 7 Daniel Roesen 2000-12-21 19:27:19 EST
Fixed in rawhide vims? I heard that newest gnome-terminal doesn't exhibit this
problem. Is it a vim bug or gnome-terminal problem?
Comment 8 Ronald Cole 2000-12-21 19:33:39 EST
I don't know.  *Something* was broken in 6.1 and 6.2.  It seems fixed in 7.0.  I
don't know about rawhide.
Comment 9 Daniel Roesen 2000-12-21 21:11:36 EST
Rawhide vim rebuilt from SRPM on 6.2 works. No more bogus "c" on stdout.
Comment 10 Pete Zaitcev 2000-12-23 22:53:58 EST
Here is the problem as I see it. In term.c, vim uses
KS_CRV to request version, with escape sequence "\033[>c".
This is taken from xterm docs, but is wrong. Actual sequence
has no '>', to which both xterm and gnome-terminal reply.
However, if one would remove '>', he/she triggers another
bug in vim: version reply is not eaten properly and it gets
input as a vim command.

The best fix is to comment out the KS_CRV entry in term.c.

Did anyone communicate this to vim folks?
