Almost correct: It doesn't bypass ZLE on ^D provided `setopt ignoreeof'.
} Here is my solution, configurable by the variable IGNOREEOF:
}
} IGNOREEOF=3 # or something like that
}
} bash-ctrl-d() {
} if [[ $CURSOR == 0 && -z $BUFFER ]]
} then
} [[ -z $IGNOREEOF || $IGNOREEOF == 0 ]] && exit
} [[ $LASTWIDGET == bash-ctrl-d ]] \
} && (( --__BASH_IGNORE_EOF == 0 )) \
} && exit
} : ${__BASH_IGNORE_EOF=$IGNOREEOF}
} zle send-break
} else
} zle delete-char-or-list
} fi
} }
With your function, IGNOREEOF=3 will require four ^D to exit, or two ^D
and then anything else, repeated four times (because it never starts
__BASH_IGNORE_EOF over at three after the first call to this function).
I think you want:
bash-ctrl-d() {
if [[ $CURSOR == 0 && -z $BUFFER ]]
then
[[ -z $IGNOREEOF || $IGNOREEOF == 0 ]] && exit
if [[ $LASTWIDGET == bash-ctrl-d ]]
then
(( --__BASH_IGNORE_EOF <= 0 )) && exit
else
(( __BASH_IGNORE_EOF = IGNOREEOF-1 ))
fi
zle send-break
else
zle delete-char-or-list
fi
}
