I've recently started using ZHS with oh-my-zsh script pack. It does excellent job except of weird ^W shortcut behavior.

For example if I have following command line and symbol ▮ denotes cursor position.

$ ./command_name --option1 value --option2=value ▮

Sequentially pressing ^W for several times I'd get following content in command prompts:

$ ./command_name --option1 value --option2=▮
$ ./command_name --option1 value --▮
$ ./command_name --option1 ▮
$ ./command_name --▮
$ ./command_▮
$ ./▮

What bugs me is that after third press cursor stops not after deleting --, but also eats value. I suspect that all symbols such as "_-" are considered as separators as spaces and zsh continues eating symbols until it deletes some non-separator chars, but I have no idea how to change this behavior.

What is echo $WORDCHARS? – slhck Oct 2 '13 at 11:37
Thanks for response. It's empty. – Nevkontakte Oct 2 '13 at 15:07

In order to fix this (default) behavior you want to have Zsh use vi-style backward-kill-word.

Put this in your ~/.zshrc:

bindkey '^W' vi-backward-kill-word

Now, it will kill to the following positions:

$ ./command_name --option1 value --option2=▮
$ ./command_name --option1 value --option2▮
$ ./command_name --option1 value --▮
$ ./command_name --option1 value ▮
$ ./command_name --option1 ▮
$ ./command_name --▮
$ ./command_name ▮
$ ./▮
$ ▮
