zsh: stop backward-kill-word on directory delimiter

Question

In zsh, how can I set up the line editor such that backward-kill-word stops on a directory separator? Currently in my bash setup, if I type

cd ~/devel/sandbox

and then hit C-w point will be right after "devel/". In my zsh setup, point would be after "cd ". I'd like to set up zsh so it behaves similarly to bash.

Answer 1

A quick google reveals:

Backward Kill

Or, perhaps a better fix:

Bash Style Backward Kill

Answer 2

For recent versions of zsh, you can simply add:

autoload -U select-word-style
select-word-style bash

to your zshrc as described in zshcontrib(1).
