Zsh copy & paste system wide for OS X, like in emacs

It's very annoying that i need to use mouse to copy text from the terminal.
Zsh provides nice emacs-like selection, although it uses its own kill-ring, and doesn't use system-wide clipboard. Oh-my-zsh doesn't help either.

So I wrote this code, to fix that. There are simple wrappers around default functions. Also there is a new behavior for ⌥-W, which is more emacs like.

You can find gist here.

pb-kill-line () {
  zle kill-line
  echo -n $CUTBUFFER | pbcopy
}

pb-kill-whole-line () {
  zle kill-whole-line
  echo -n $CUTBUFFER | pbcopy
}

pb-backward-kill-word () {
  zle backward-kill-word
  echo -n $CUTBUFFER | pbcopy
}

pb-kill-word () {
  zle kill-word
  echo -n $CUTBUFFER | pbcopy
}

pb-kill-buffer () {
  zle kill-buffer
  echo -n $CUTBUFFER | pbcopy
}

pb-copy-region-as-kill-deactivate-mark () {
  zle copy-region-as-kill
  zle set-mark-command -n -1
  echo -n $CUTBUFFER | pbcopy
}

pb-yank () {
  CUTBUFFER=$(pbpaste)
  zle yank
}
