Hi there,
I suggest that the IGNORE_EOF shell option should be implemented in the
same way as in bash. There, it is a shell variable rather than an option.
The best explanation is given in the bash manual page:
IGNOREEOF
Controls the action of an interactive shell on
receipt of an EOF character as the sole input. If
set, the value is the number of consecutive EOF
characters which must be typed as the first charac
ters on an input line before bash exits. If the
variable exists but does not have a numeric value,
or has no value, the default value is 10. If it
does not exist, EOF signifies the end of input to
the shell.
The advantage is that a user can set that variable to 3, for example, to log
out after three presses of ^D.
If you should not like to hard-code it into the shell, you should consider
the following workaround: the shell must not catch ^D on an empty command
line before any invocation of a zle widget. If ^D on an empty command is
passed to zle, too, users can write their own zle widget which ignores it,
let's say 3 times, and then logs out.
Regards,
Christoph
