bash-powerline

Powerline for Bash in pure Bash script.

Features

• Git: show branch name, tag name, or unique short hash.
• Git: show "*" symbol with uncommited modifications.
• Git: show "↑" symbol and number of commits ahead of remote.
• Git: show "↓" symbol and number of commits behind remote.
• Platform-dependent prompt symbols.
• Color-coded prompt symbol according to previous command execution status.
• Use Bash builtin when possible to reduce delay. Delay sucks!
• No need for patched fonts.

Installation

Download the Bash script

curl https://raw.githubusercontent.com/riobard/bash-powerline/master/bash-powerline.sh > ~/.bash-powerline.sh

And source it in your .bashrc

source ~/.bash-powerline.sh

For best result, use Solarized colorscheme for your terminal emulator. Or hack your own colorscheme by modifying the script. It's really easy.

Why?

This script is inspired by powerline-shell, which is implemented in Python. Python scripts are much easier to write and maintain than Bash scripts, but invoking Python interpreter introduces noticable delay to draw. I hate delays, so I ported just the part I need to pure Bash script.

The other reason is that I don't like the idea of patching fonts. The font patching mechanism from the original Powerline does not work with the bitmap font (Apple Monaco without anti-aliasing) I use on non-retina screens. I'd rather stick with existing unicode symbols.
