Copying current command line to clipboard

Question

In bash with set -o vi, I use

bind '"\C-]":"\C-[A\C-u cb <<"EOF"\n\C-y\nEOF\n"'

to make ^] in insert mode cat the current line to my clipboard wrapper (cb).

How do I emulate this in zsh (with set -o vi) ?

Answer 1

These work for me:

copy-to-xclip() {
    zle kill-buffer
    print -rn -- $CUTBUFFER | cb
}; zle -N copy-to-xclip
bindkey -M viins "^]" copy-to-xclip

paste-xclip() {
    killring=("$CUTBUFFER" "${(@)killring[1,-2]}")
    CUTBUFFER=$(xclip -selection clipboard -o)
    zle yank
}; zle -N paste-xclip
bindkey -M vicmd "p" paste-xclip
