# Example of a widget that takes a vi motion
# Filter part of buffer corresponding to a vi motion through an external
# program.
# To enable with vi compatible bindings use:
# autoload -Uz vi-pipe
# bindkey -a '!' vi-pipe
setopt localoptions noksharrays
autoload -Uz read-from-minibuffer
local _save_cut="$CUTBUFFER" REPLY
# mark this widget as a vi change so it can be repeated as a whole
zle -f vichange
# force movement to default to line mode
(( REGION_ACTIVE )) || zle -U V
# Use the standard vi-change to accept a vi motion.
zle .vi-change || return
read-from-minibuffer "!"
zle .vi-cmd-mode
local _save_cur=$CURSOR
# cut buffer contains the deleted text and can be modified
CUTBUFFER=$(eval "$REPLY" <<<"$CUTBUFFER")
# put the modified text back in position.

# at the beginning of a line, vi-delete won't have moved the cursor
# back to a previous line
