# Bullet Train for oh-my-zsh ![Travis CI](https://travis-ci.org/caiogondim/bullet-train-oh-my-zsh-theme.svg) [![Slack Status](https://bullet-train-zsh-slack.herokuapp.com/badge.svg)](https://bullet-train-zsh-slack.herokuapp.com/)
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
- 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 **after** the
line `zplug "robbyrussell/oh-my-zsh"`.
```bash
setopt prompt_subst # Make sure propt is able to be generated properly.
zplug "adambiggs/zsh-theme", use:adambiggs.zsh-theme
```
## 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, please see [Tips](#tips) for
more details.

## Tips
### BULLETTRAIN_PROMPT_ORDER
This gives ability to customize order and put user-defined segment on prompt.
```bash
prompt_say_hello() {
prompt_segment yellow blue "hello"
}
BULLETTRAIN_PROMPT_ORDER=(
git
dir
say_hello
)
```
![Prompt_Order](./img/tips/prompt_order.png)
### BULLETTRAIN_GIT_PROMPT_CMD
Allows you to specify custom git prompt command. This makes it possible to
change:
![Git_Prompt_Origin](./img/tips/git_prompt_origin.png)
into:
![Git_Prompt_Command](./img/tips/git_prompt_command.png)
with:
``` bash
BULLETTRAIN_GIT_PROMPT_CMD=\${\$(git_prompt_info)//\\//\ \ }
```
Please note we need to delay variable expansion, so we have to escape all
**weird** character - *$*, *\*, *\<space>*, etc.
You can also use function to get more complex commands:
``` bash
BULLETTRAIN_GIT_PROMPT_CMD="\$(custom_git_prompt)"
custom_git_prompt() {
prompt=$(git_prompt_info)
prompt=${prompt//\//\ \ }
prompt=${prompt//_/\ }
echo ${prompt}
}
```
which gives:
