Package: powerline-go (1.25-2 and others)

Powerline style prompt for your shell: Bash, ZSH and Fish

 - Shows some important details about the git/hg branch
 - Changes color if the last command exited with a failure code
 - If you're too deep into a directory tree, shortens the displayed path with
   an ellipsis
 - Shows the current Python virtualenv environment
 - Shows the current Ruby version using rbenv or rvm
 - Shows if you are in a nix shell
 - It's easy to customize and extend.

To use it, add the following to your ~/.bashrc:

 function _update_ps1() {
     PS1="$(/usr/bin/powerline-go -error $? -jobs $(jobs -p | wc -l))"

     # Uncomment the following line to automatically clear errors after showing
     # them once. This not only clears the error for powerline-go, but also for
     # everything else you run in that shell. Don't enable this if you're not
     # sure this is what you want.

     #set "?"
 }

 if [ "$TERM" != "linux" ] && [ -f "/usr/bin/powerline-go" ]; then
     PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
 fi

Or to your ~/.zshrc:

 function powerline_precmd() {
     PS1="$(/usr/bin/powerline-go -error $? -jobs ${${(%):%j}:-0})"

     # Uncomment the following line to automatically clear errors after showing
     # them once. This not only clears the error for powerline-go, but also for
     # everything else you run in that shell. Don't enable this if you're not
     # sure this is what you want.

     #set "?"
 }

 function install_powerline_precmd() {
   for s in "${precmd_functions[@]}"; do
     if [ "$s" = "powerline_precmd" ]; then
       return
     fi
   done
   precmd_functions+=(powerline_precmd)
 }

 if [ "$TERM" != "linux" ] && [ -f "/usr/bin/powerline-go" ]; then
     install_powerline_precmd
 fi

For fish, redefine fish_prompt in ~/.config/fish/config.fish:

 function fish_prompt
     eval /usr/bin/powerline-go -error $status -jobs (count (jobs -p))
 end
