making zsh beep

making zsh beep

Hi all,

I have installed zsh as a login shell and have done a bunch of 
configuring, but there is one feature I would like it to do that bash 
used to do, and cannot seem to locate any info on it.

In bash, backspacing on an empty command line produced a beep. How can I 
make zsh do that?

I have setopt beep in a startup file, and ambiguous filename expansions 
cause a beep. But backspacing on an empty command line does not. What 
have I overlooked?

Thanks,

Chuck

Hi Charles,
If you'd like the line editor to beep, you'll have to add a widget
that does that. I don't think that there's an option for that.
Try:

backward-delete-char-beep() {
  if (( CURSOR == 0 )) ; then
    zle beep ;
  fi ; 
  zle backward-delete-char
}
zle -N backward-delete-char-beep
bindkey "^?" backward-delete-char-beep

That should do the trick.
