Bullet Train is a [oh-my-zsh shell](https://github.com/robbyrussell/oh-my-zsh)
theme based on the
[Powerline Vim plugin](https://github.com/Lokaltog/vim-powerline). It aims for
simplicity, showing information only when it's relevant.

It currently shows:
- Current Python virtualenv
- Current Ruby version and gemset, through RVM
- Current Node.js version, through NVM
- Git status
- Timestamp
- Current directory
- Background jobs
- Exit code of last command

If you want add some new feature, of fix some bug, open an issue and lets hack
together.

For a tmux theme to work with it, i suggest [Maglev](https://github.com/caiogondim/maglev).

## Requirements

In order to use the theme, you will first need:

* Powerline compatible fonts like [Vim Powerline patched fonts](https://github.com/Lokaltog/powerline-fonts), [Input Mono](http://input.fontbureau.com/) or [Monoid](http://larsenwork.com/monoid/).
* A ZSH framework like [antigen](https://github.com/zsh-users/antigen), [oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh) or [zgen](https://github.com/tarjoilija/zgen)
* Make sure terminal is using 256-colors mode with `export TERM="xterm-256color"`
* For [iTerm 2](http://iterm2.com/) users, make sure you go into your settings and set both the regular font and the non-ascii font to powerline compatible [fonts](https://github.com/powerline/fonts) or the prompt separators and special characters will not display correctly.
