How to save the current working directory to Zsh history?

Question

I wanted to achieve the same as asked here Saving current directory to bash history but within Zsh shell. I haven't done any Zsh trickery before but so far I have:

function precmd {
  hpwd=$history[$((HISTCMD-1))]  
  if [[ $hpwd == "cd" ]]; then  
    cwd=$OLDPWD
  else
    cwd=$PWD
  fi
  hpwd="${hpwd% ### *} ### $cwd"
  echo "$hpwd" >>~/.hist_log
}

Right now I save the command annotated with the directory name to a log file. This works fine for me. Just thought there might be a way to make the same replacement in the history buffer itself.

Answer 1

function _-accept-line() {
    [[ -z "${BUFFER" ]] || [[ "${BUFFER}" =~ "### ${(q)PWD}\$" ]] || BUFFER="${BUFFER} ### ${PWD}"
    zle .accept-line
}
zle -N accept-line _-accept-line

Will add ### ${PWD} to your command line. Not the best solution you could use, but it works.

UPD: Answer based on @Dennis Williamson's comment:

function zshaddhistory() {
    print -sr "${1%%$'\n'} ### ${PWD}"
    fc -p
}
