# Bullet Train for oh-my-zsh <a href="https://www.irccloud.com/invite?channel=bullettrain-sh&amp;hostname=irc.freenode.net&amp;port=6697&amp;ssl=1" target="_blank"><img src="https://img.shields.io/badge/IRC-bullettrain–sh-1e72ff.svg?style=flat" height="20"></a>

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; when using Pyenv and no active virtualenv shows the current Python version the shell uses
- Current Ruby version using chruby; version and gemset when on RVM or Rbenv
- Current Node.js version, through NVM (if present) or Node.js
- Current Perl version using plenv
- Current Elixir version
- 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).

## Preview

![Preview](http://raw.github.com/caiogondim/bullet-train-oh-my-zsh-theme/master/img/preview.gif)


## 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/).
* On Ubuntu like systems you'll need the `ttf-ancient-fonts` package to correctly display some unicode symbols that are not covered by the Powerline fonts above.
* 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.


## Installing

### For oh-my-zsh users

1. Download the theme [here](http://raw.github.com/caiogondim/bullet-train-oh-my-zsh-theme/master/bullet-train.zsh-theme)

2. Put the file **bullet-train.zsh-theme** in **$ZSH_CUSTOM/themes/**

3. Configure the theme in your **~/.zshrc** file:

```bash
ZSH_THEME="bullet-train"
```

### For antigen users

Add the following snippet to your **.zshrc** somewhere after the line
`antigen use oh-my-zsh`.

```bash
antigen theme https://github.com/caiogondim/bullet-train-oh-my-zsh-theme bullet-train
```

### For Zgen users

If you're using [zgen](https://github.com/tarjoilija/zgen), add the following line to your **~/.zshrc** where you're adding your other zsh plugins **after** the line `zgen oh-my-zsh`.

```bash
zgen load caiogondim/bullet-train-oh-my-zsh-theme bullet-train
```

### For Zplug users

If you're using [zplug](https://github.com/zplug/zplug), add the following line
to your **~/.zshrc** where you're adding your other zsh plugins.

```bash
setopt prompt_subst # Make sure prompt is able to be generated properly.
zplug "caiogondim/bullet-train.zsh", use:bullet-train.zsh-theme, defer:3 # defer until other plugins like oh-my-zsh is loaded
```

## Options

Bullet Train is configurable. You can change colors and which segments you want
or don't want to see. All options must be overridden in your **.zshrc** file.

### Order
`BULLETTRAIN_PROMPT_ORDER` defines order of prompt segments. Use zsh array
syntax to specify your own order, e.g:

```bash
BULLETTRAIN_PROMPT_ORDER=(
  git
  context
  dir
  time
)
```

NOTE: You do not need to specify *end* segment - it will be added automatically. With this you can also specify custom segments.
