How to send output to next input line?

Question

This my snippet alias hst="history 1 -1 | cut -c 8- | uniq | fzf ". when I run hst The output is

$ ~ hst
(the output from hst)
$

This is what I want

$ ~ hst
$ (the output from hst)

Example

$ ~ hst
vi .zshrc
$

should be

$ ~ hst
$ vi .zshrc

How to fix this? (or enhance the script)

Answer 1

To add something to the shell input stack as if it was input by the user, you'd use print -z:

hst() {
  local cmd
  cmd=$(print -rNC1 -- ${(u)history} | fzf --read0 "$@") &&
    print -rz -- $cmd
}
