backward kill

backward kill

[Jesper Holmberg]

Hi all,

I am using the emacs key bindings. If I've written the following:

/path/to/some/file

with the prompt at the end, and I press alt-backspace, the whole path is
wiped out. I would like it to just remove backwards to the last (first
from the end) slash. How could I accomplish this?

TIA

Jesper

Use the bash-backward-kill-word widget, supplied with 4.0 and 4.1.  (The
other bash-* variants are only supplied with 4.1).

Cannot seem to get that working, and the manpage mentions nothing
about it?

(mmj@staudinger) ~> echo $ZSH_VERSION
4.0.4

(mmj@staudinger) ~> echo $ZSHEDIT
emacs

(mmj@staudinger) ~> cat .zshrc | grep bash
bindkey "^[^[[D" bash-backward-kill-word

And when I hit ESC left-arrow:
No such widget `bash-backward-kill-word'

It's documented in zshcontrib(1), but only in 4.1.  I think I'll copy the
remainder of the bash-* stuff to the 4.0 branch.

The file tells you what to do.  Make sure the directory is in your autoload
path --- zsh should have been set up so that it is --- and autoload it like
any other function.

# This implements a bash-style backward-kill-word.
# To use,
#   zle -N bash-backward-kill-word
#   bindkey '...' bash-backward-kill-word
# or if you wish to replace existing backward-kill-word bindings,
#   zle -N backward-kill-word bash-backward-kill-word

i use this bit contributed by someone on the list (Oliver Kiddle); check
the archives from Mon, Oct. 8 for more info on this:

tcsh-backward-delete-word () {
  local WORDCHARS="${WORDCHARS:s#/#}"
  zle backward-delete-word
}

i have it bound to control-W with:
bindkey '^W' tcsh-backward-delete-word

but you can change that obviously.

i think that's what you're looking for, no?

the '$WORDCHARS' variable is how zsh determines word boundaries so you
could add '/' to that globally, however this might affect other things
you want to leave it for, so i prefer this function.
