Add 'transform' action to conditionally perform a series of actions
'transform' action runs an external command that prints a series of
actions to perform.
# Disallow selecting an empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"'
# Move cursor past the empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"' \
--bind 'focus:transform:[[ -n {} ]] && exit; [[ {fzf:action} =~ up$ ]] && echo up || echo down'
