Powerline style prompt for Zsh

This is a fork from https://github.com/milkbikis/powerline-bash

A Powerline like prompt for Zsh:

• Shows some important details about the git branch:
  • Displays the current git branch which changes background color when the branch is dirty
  • A '+' appears when untracked files are present
  • When the local branch differs from the remote, the difference in number of commits is shown along with '⇡' or '⇣' indicating whether a git push or pull is pending
• 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
• It's all done in a Python script, so you could go nuts with it

Setup

• This script uses ANSI color codes to display colors in a terminal. These are notoriously non-portable, so may not work for you out of the box, but try setting your $TERM to xterm-256color, because that works for me. i.e. edit your .zshrc file to add:

export TERM='xterm-256color'

If you still face problems seeing colors then read this: https://gist.github.com/3749830#file_powerline_zsh_instructions.md

• Patch the font you use for your terminal. Download the font from: https://github.com/Lokaltog/vim-powerline/wiki/Patched-fonts Follow the instructions: https://github.com/Lokaltog/vim-powerline/tree/develop/fontpatcher#font-patching-guide

• Clone this repository somewhere:

git clone https://github.com/carlcarl/powerline-zsh

• Create a symlink to the python script in your home:

ln -s <path/to/powerline-zsh.py> ~/powerline-zsh.py

If you don't want the symlink, just modify the path in the .zshrc command below

• Now add the following to your .zshrc:

function _update_ps1()
{
    export PROMPT="$(~/powerline-zsh.py $?)"
}
precmd(){
    _update_ps1
}
