Installation

Prerequisites

Fonts

This quickstart includes the bullet-train ZSH theme, which requires a Powerline-compatible font in your terminal to display certain status glyphs. Fonts that are Powerline-compatible include many useful glyphs, including the nice branch icon that the theme in this .zshrc uses.

Here are a few good Powerline-compatible fonts I've found:

  • Awesome Terminal Fonts - A family of fonts that includes some nice monospaced Icons.
  • Fantasque Awesome Font - A nice monospaced font, patched with Font-Awesome, Octoicons and Powerline-Glyphs.
  • Fira Mono - Mozilla's Fira type family.
  • Hack - Another Powerline-compatible font designed specifically for source code and terminal usage.
  • Input Mono - A family of fonts designed specifically for code. It offers both monospaced and proportional fonts and includes Powerline glyphs.
  • Iosevka - Iosevka is an open source slender monospace sans-serif and slab-serif typeface inspired by Pragmata Pro, M+ and PF DIN Mono, designed to be the ideal font for programming.
  • Monoid - Monoid is customizable and optimized for coding with bitmap-like sharpness at 15px line-height even on low res displays.
  • Mononoki - Mononoki is a typeface by Matthias Tellen, created to enhance code formatting.
  • Nerd fonts - A collection of over 20 patched fonts (over 1,700 variations) & fontforge font patcher python script for Powerline, devicons, and vim-devicons: includes Droid Sans, Meslo, AnonymousPro, ProFont, Inconsolta, and many more.
  • Powerline patched font collection - A collection of a dozen or so fonts patched to include Powerline gylphs.
  • spacemono - Google's new original monospace display typeface family.

OS-specific setup

macOS

  1. Download iTerm2 from http://www.iterm2.com. It is considerably nicer than the stock Terminal application that comes with macOS.
  2. Install the current version of Homebrew from http://brew.sh/.
  3. Install GNU Stow with brew install stow
  4. Homebrew has a newer version of zsh than the one Apple ships, so brew install zsh to install it.
  5. Switch your shell to zsh:
    1. System Preferences -> Users & Groups.
    2. Unlock the preferences
    3. Select your user
    4. Select advanced options
    5. Set your login shell to /bin/zsh (or /usr/local/bin/zsh if you decided to use the newer version packaged by brew)
  6. Install some Powerline-compatible fonts from one of the links in the Fonts section above.
    1. In iTerm 2, go to Preferences->Profile in your iTerm 2 preferences, then select one of the Powerline-compatible fonts you just installed.
    2. Make sure you also specify a Powerline-compatible font for non-ASCII in your iTerm 2 preferences or the prompt separators and branch glyphs will show up garbled.

Linux

  1. Switch your shell to zsh with chsh -s /bin/zsh
  2. Install GNU Stow - yum install -y stow on Red Hat / CentOS systems, apt-get -y install stow on Debian / Ubuntu.
  3. Install the patched font in a valid X font path. Valid font paths can be listed with xset q: mv YourChosenPowerlineFont.otf ~/.fonts
  4. Update the font cache for the path the font was installed in (root privileges may be needed for updating font cache for some paths): fc-cache -vf ~/.fonts/

After installing a Powerline-compatible font, you will also need to configure your terminal emulator to use your selected Powerline-compatible font. The name of the correct font usually ends with for Powerline.

If the Powerline symbols cannot be seen, try closing all instances of the terminal emulator. The X Server may also need to be restarted for the new font to correctly load.

If you still can’t see the new Powerline fonts then double-check that the font has been installed to a valid X font path.

If you get garbled branch glyphs, make sure there isn't a separate font setting for non-ASCII characters in your terminal application that you also need to set to use a Powerline-compatible font. Konsole needs to be set to use UTF-8 encoding, for example.

Set up Zgen and the starter kit

Now that your fonts and default shell have been set up, install zgen and the dotfiles from this starter kit repository.

  1. Install Zgen
    1. cd ~
    2. git clone git@github.com:tarjoilija/zgen.git
  2. Install the starter kit
    1. cd ~
    2. git clone git@github.com:unixorn/zsh-quickstart-kit.git
  3. Configure zsh by symlinking the .zshrc, .zsh_aliases and .zsh-completions from this repo into your ~.
    1. You can do this with stow by:
      1. cd zsh-quickstart-kit
      2. stow --target=/Users/YourUsername zsh. Replace /Users/YourUsername with /home/YourUsername if you're on Linux.

The .zshrc, .zsh_aliases & .zsh_functions files included in this kit enable:

Contents of the kit

The zsh-quickstart-kit configures your ZSH environment so that it includes:

  • Automatic periodic updates of both zgen and your plugins
  • Cross-session shared history so commands typed in one terminal window can be seen and searched in all your other ZSH sessions on the same machine.
  • Deduplicating your command history.
  • Many more tab completions, courtesy of the zsh-users/zsh-completions repository, and periodic updating to tip of master of that repository so you get updates to the extra tab completions.
  • Proper command history search.
  • Syntax highlighting at the command line.
  • Tab completion of Rakefile targets.
  • Enabling oh-my-zsh-compatible plugins and themes (via the zgen framework).
  • Various helper functions for interacting with macOS's clipboard, audio volume, Spotlight and Quicklook. For your convenience, these will only load if you are on a macOS machine so you can use the same plugin list on any *NIX system.

Included plugins:

The quickstart kit also uses zgen to load oh-my-zsh and these plugins:

  • aws
  • brew - only loaded on macOS
  • chruby
  • colored-man
  • git
  • github
  • osx - only loaded on macOS
  • pip
  • python
  • rsync
  • screen
  • sudo
  • vagrant

Customizing the kit

Functions and Aliases

The .zshrc included in this kit will automatically source any files it finds in ~/.zshrc.d. This makes it easy for you to add extra functions and aliases without having to maintain a separate fork of this repository. The files will be sourced in alphanumeric order and I suggest you use a naming scheme of 001-onething, 002-something-else etc to ensure they're loaded in the order you expect.

ZSH options.

The quickstart kit does an opinionated (i.e. my way) setup of ZSH options and adds some functions and aliases I like on my systems. However, ~/.zshrc.d is processed after the quickstart sets its aliases, functions and ZSH options, so if you don't care for something as set up in the quickstart, you can override the offending item in a shell fragment file there.

Self-update Settings

The quickstart kit will check for updates every seven days. If you want to change the interval, set QUICKSTART_KIT_REFRESH_IN_DAYS in a file in ~/.zshrc.d. If you want to disable self updating entirely, add unset QUICKSTART_KIT_REFRESH_IN_DAYS in a file in ~/.zshrc.d.

Changing the zgen plugin list

I've included what I think is a good starter set of zsh plugins in this repository. However, everyone has their own preferences for their environment. To make the list easier to customize without having to maintain a separate fork of this kit, if you create a file named ~/.zgen-local-plugins, the .zshrc from this starter kit will source that instead of running the load-starter-plugin-list function defined in ~/.zgen-setup.

Using ~/.zgen-local-plugins is not additive, it will completely replace the kit-provided list of plugins.

It's a pain to create .zgen-local-plugins from scratch, so to make customizing your plugins easier, I've included a .zgen-local-plugins-example file at the root of the repository that will install the same plugin list that the kit does by default that you can use as a starting point for your own customizations.

Copy that to your $HOME/.zgen-local-plugins, change the list and the next time you start a terminal session you'll get your list instead of mine.

FAQ

Stow complains with a Warning! that stowing zsh would cause conflicts

You ran stow --target=/Users/YourUsername zsh in the top level of the repo, and stow printed the following error:

WARNING! stowing zsh would cause conflicts:
  * existing target is neither a link nor a directory: .zshrc
All operations aborted.

Per @jefheaton, this is caused when trying to replace an existing .zshrc file. He fixed it by closing ~ in Finder so Finder wouldn't create a .DS_Store file, deleting the existing .DS_Store, and then removing the old .zshrc. You may have to rename it first if ZSH is keeping the file open, then deleting it after closing all your Terminal/iTerm 2 windows.

Dotfiles in general

dotfiles.github.io/ has a lot of great resources for dotfiles - frameworks for managing them, configurations for editors and other bootstraps with initial configurations to start from.

Vim

If you're using vim, spf13 is an excellent starter configuration and plugin collection.
