Or use starship...

It's too bloated. It has all kinds of built-in stuff with ugly defaults instead of just providing a framework with plugins.

Starship is the only prompt I've used that has (a) sane defaults, (b) cross platform support as well as ease of installation, and (c) good enough speed. Powerline is much slower, and I lose my serenity everytime I have to fiddle with dotfiles.

Here's what I'm currently rocking:

    0 0:00:00
    ~/Code/company/app$
First number is exit code of previous command, second is how long it took. Credit to https://unix.stackexchange.com/questions/252229/ps1-prompt-t... for the last part. It's a bit ratchet:

- I actually don't care about the exit code unless it was non-zero

- It calculates the delta three times

but I've been to busy to optimise it.

    prompt_command() {
      _PS1_now=$(printf '%(%s)T')
      PS1=$( printf "\n\$? \[\e%02d:%02d:%02d \n\[\033[01;34m\]\w\[\033[00m\]\$ " \
              $((  ( _PS1_now - _PS1_lastcmd ) / 3600))         \
              $(( (( _PS1_now - _PS1_lastcmd ) % 3600) / 60 )) \
              $((  ( _PS1_now - _PS1_lastcmd ) % 60))           \
          )
      _PS1_lastcmd=$_PS1_now
    }
    PROMPT_COMMAND='prompt_command'
    _PS1_lastcmd=$(printf '%(%s)T')

I've shared it elsewhere too, but I made something similar a few years ago which provides what you were after:

Very cool, had no idea!

I think the drag-n-drop UI is less intuitive. Wasted a few minutes trying to click these items as "buttons" and wondering if there's something wrong because of the http-onlyness of the site (console gives a lot of warning).

double click an element to change the color

Aha! Thank you!

Yea, why not just have "double-click" as "add this element to the end of input".

current git branch is missing (helps me to avoid working on the wrong branch). (tried to do it with colors, but things got too messy). I never managed to work with colors in bash propmts; they look different on each environment.

  parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
  }

  PS1="[\u@\h \W\$(parse_git_branch)]\$ "
