How to achieve short working directory about magicmace HOT 9 CLOSED

@KiteAB, it's been only 14 hours since your reply, and now you sound demanding. It's not fair to address me or any other person who puts their free time in trying to build a great piece of software, in this manner.

Oh, sorry. Sorry to bother you, my problem has been basically solved, thank you

I am surprised that you can give the final answer, thank you very much!

Like from this: ~/Documents/GitHub
To this: ~/D/GitHub
And apply it to my gitster theme

Hi @KiteAB, this is the code that shortens the pwd:

  local current_dir=${PWD/#${HOME}/~}"
  if [[ ${current_dir} != '~' ]]; then
    current_dir="${${(@j:/:M)${(@s:/:)current_dir:h}#?}%/}/${current_dir:t}"
  fi

The longest line is doing most of the work:

1. /${current_dir:t}: keep the tail directory (last directory in the path)
2. ${(@s:/:)current_dir:h}: split the remaining directories into an array
3. ${(@j:/:M)...#?}: join the first letter of the array elements
4. ${...%/}: remove extra slash in case we're in the root directory

You can apply the same code to your custom prompt. If you want to use that with gitster, it will look like:

  local git_root current_dir
  if git_root=$(command git rev-parse --show-toplevel 2>/dev/null); then
    current_dir="${PWD#${git_root:h}/}"
  else
    current_dir=${PWD/#${HOME}/~}"
  fi
  if [[ ${current_dir} != '~' ]]; then
    current_dir="${${(@j:/:M)${(@s:/:)current_dir:h}#?}%/}/${current_dir:t}"
  fi
  print -n "%F{white}${current_dir}"

It's working! But there are still some small problems:
In git repositories, It's look's not nice.

@KiteAB, you might want to use this with gitster. It will keep the git root directory unshortened too, which I think goes well with the spirit of this prompt:

  local git_root current_dir
  if git_root=$(command git rev-parse --show-toplevel 2>/dev/null); then
    current_dir="${PWD#${git_root:h}/}"
  else
    current_dir=${(%):-%~}
  fi
  local -r dirs=("${(@s:/:)current_dir}")
  if (( ${#dirs} > 2 )); then
    current_dir="${dirs[1]}/${(@j:/:M)dirs[2,-2]#?}/${dirs[-1]}"
  fi
  print -n "%F{white}${current_dir}"
