:bullettrain_side: An oh-my-zsh shell theme based on the Powerline Vim plugin

Bullet Train for oh-my-zsh

Bullet Train is a oh-my-zsh shell theme based on the Powerline Vim plugin. 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.

Requirements

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

• Powerline compatible fonts like Vim Powerline patched fonts, Input Mono or 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, oh-my-zsh or zgen
• Make sure terminal is using 256-colors mode with export TERM="xterm-256color"
• For iTerm 2 users, make sure you go into your settings and set both the regular font and the non-ascii font to powerline compatible fonts or the prompt separators and special characters will not display correctly.

Installing

For oh-my-zsh users

1. Download the theme here

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

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

ZSH_THEME="bullet-train"

For antigen users

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

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

For Zgen users

If you're using zgen, add the following line to your ~/.zshrc where you're adding your other zsh plugins after the line zgen oh-my-zsh.

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

For Zplug users

If you're using zplug, add the following line to your ~/.zshrc where you're adding your other zsh plugins.

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:

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.

Kubernetes Context

The prompt will first check if BULLETTRAIN_KCTX_KUBECTL=true and kubectl is installed than it will use kubectl config view --minify to determine the context and default namespace in use. If BULLETTRAIN_KCTX_KUBECTL=false or kubectl is not installed, BULLETTRAIN_KCTX_KCONFIG will be parsed to get the current context.

The usage of kubectl allow the prompt to get the default namespace even if you are using multiple kube config files (e.g. KUBECONFIG=~/.kube/config:path-to-config1:path-to-config2)

AWS Profile

Displays which AWS (Amazon Web Services) credentials profile is currently set. This environment var is used by aws-cli and other tools to use the right access keys and other parameters.

Perl

Dir

Git

The git prompt can be disabled for a specific repository by setting a git config flag: git config oh-my-zsh.hide-status 1. This is useful to avoid performance issues for particularly huge repositories.
