Powerline-style Bash prompt in pure Bash script

bash-powerline (JCBR Info’s fork)

Powerline-style Bash prompt in pure Bash script.

This a fork of riobard/bash-powerline that includes many portability fixes and improvements.

Features

• Git status
  • Displays current git branch name, or short SHA1 hash when the head is detached
  • Displays the + symbol when current branch has uncommited changes
  • Displays the ⇡ symbol and the difference in the number of commits when the current branch is ahead of the remote
  • Displays the ⇣ symbol and the difference in the number of commits when the current branch is behind of the remote
• Status code for the previously failed command
• Fast execution (no noticable delay)
• No need for patched fonts
• More portable than the original bash-powerline script: Works on 16-colors terminals and does not rely on particular language settings.
• Highly customizable

Installation

Download the Bash script

curl https://raw.github.com/jcbrinfo/bash-powerline/master/bash-powerline.sh > ~/.bash-powerline.sh

And source it in your .bashrc

. "$HOME/.bash-powerline.sh"

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

Note: Some colors may not appear as expected. In order to fix this, change the value of the POWERLINE_TERM_COLOR_ENCODING constant of your bash-powerline.sh file. For details, see the comments in the script.

Why?

Because we should not need a Python interpreter and a patched font to display a poweline-style Bash prompt.

bash-powerline's Issues

Support Fossil

Considering we have a segment for Git, it will be great to have a segment for Fossil too.

Git fatal errors are displayed

For example, when I am in a interactive rebase, I get the following lines before the prompt:

fatal: HEAD ne pointe pas sur une branche
fatal: HEAD ne pointe pas sur une branche

It is really annoying, since the error messages mixes with the output of the last run command.
