powerlevel9k Theme for ZSH

Powerlevel9k is a theme for ZSH which uses Powerline Fonts, thus giving you the most epic terminal styling in the universe.

Look like a bad-ass. Impress everyone in 'Screenshot Your Desktop' threads. Use powerlevel9k.

Powerlevel9k can be used with vanilla ZSH, Oh-My-Zsh, or Prezto, and can also be installed using antigen.

In addition to looking amazing, this theme actually provides a lot of useful information in configurable prompt segments. Here is an example of what it looks like with a normal installation and default settings:

Features

  • Supports git and mercurial repo information through ZSH's VCS_INFO:
    • branch / tag name
    • current action status (rebasing, merging, etc.,)
    • being behind / ahead of your remote by some number of commits
    • number of stashes (git only)
    • conditionally shows remote tracking branch if the name differs from local
    • current active bookmark (mercurial only)
    • various working tree statuses (e.g., unstaged, staged, etc.,)
  • Shows return-code of the last command if it is an error code
  • Indicates background jobs with a gear icon
  • Can conditionally display the user@host string when needed (e.g., SSH)
  • Provides segment for command history (so you can $ !<num> to re-run)
  • Plenty of additional segments to choose from (e.g., AWS, ruby)
  • Can be used as a single or double-lined prompt (see screenshots below)
  • Several built-in color configurations to choose from

If you would like an OMZ theme that provides some of the same features but doesn't require Powerline fonts, check out the sister font, hackersaurus.

Here is a detailed screenshot showing powerlevel9k with default settings and varying terminal status indicators:

Installation

There are two steps to start using this theme:

  1. Install the Powerlevel9k theme.
  2. Install Powerline-patched fonts.
  3. [Optional] Configuration

To get the most out of Powerlevel9k, you need to install both the theme as well as Powerline-patched fonts, if you don't have them installed already. If you cannot install Powerline-patched fonts for some reason, follow the instructions below for a compatible install.

No configuration is necessary post-installation if you like the default settings, but there is plenty of segment configuration available if you are interested.

Step 1: Install Powerlevel9k

There are four ways to install and use the Powerlevel9k theme: vanilla ZSH, Oh-My-Zsh, Prezto, and antigen. Do one of the following:

Option 1: Install for Vanilla ZSH

If you use just a vanilla ZSH install, simply clone this repository and reference it in your ~/.zshrc:

$ git clone https://github.com/bhilburn/powerlevel9k.git
$ echo 'source  powerlevel9k/powerlevel9k.zsh-theme' >> ~/.zshrc
Option 2: Install for Oh-My-ZSH

To install this theme for Oh-My-Zsh, clone this repository into your OMZ custom/themes directory.

$ cd ~/.oh-my-zsh/custom
$ git clone https://github.com/bhilburn/powerlevel9k.git themes/powerlevel9k

You then need to select this theme in your ~/.zshrc:

ZSH_THEME="powerlevel9k/powerlevel9k"
Option 3: Install for Prezto

To install this theme for use in Prezto, clone this repository into your Prezto prompt/external directory.

$ cd ~.zprezto/modules/prompt/external
$ git clone https://github.com/bhilburn/powerlevel9k.git
$ ln -s powerlevel9k/powerlevel9k.zsh-theme ../functions/prompt_powerlevel9k_setup

You then need to select this theme in your ~/.zpreztorc:

zstyle ':prezto:module:prompt' theme 'powerlevel9k'
Option 4: Install for antigen

If you prefer antigen, just add this theme to the antigen config in your ~/.zshrc:

$ echo 'antigen theme bhilburn/powerlevel9k powerlevel9k' >> ~/.zshrc
$ echo 'antigen apply' >> ~/.zshrc

Note that you should define any customizations before calling antigen theme (i.e. setting the POWERLEVEL9K_* variables) in your .zshrc.

Step 2: Install Powerline Fonts

Technically, you don't have to install Powerline fonts. If you are using a font that has some of the basic glyphs we need, you can use the theme in compatible mode - see the third option, below.

To get the most out of theme, though, you'll want Powerline-patched fonts. There are two varieties of these: 'Powerline Fonts' and 'Awesome Powerline Fonts'. The latter includes additional glyphs that aren't required for a normal install.

Do one of the following:

Option 1: Install Powerline Fonts

You can find the [installation instructions for Powerline Fonts here] (https://powerline.readthedocs.org/en/latest/installation/linux.html#fonts-installation). You can also find the raw font files in this Github repository if you want to manually install them for your OS.

After you have installed Powerline fonts, make the default font in your terminal emulator the Powerline font you want to use.

This is the default mode for Powerlevel9k, and no further configuration is necessary.

N.B.: If Powerlevel9k is not working properly, it is almost always the case that the fonts were not properly installed, or you have not configured your terminal to use a Powerline-patched font!

Option 2: Install Awesome Powerline Fonts

Alternatively, you can install Awesome Powerline Fonts, which provide a number of additional glyphs.

You then need to indicate that you wish to use the additional glyphs by defining the following in your ~/.zshrc:

POWERLEVEL9K_MODE='awesome-patched'

If you choose to make use of this, your prompt will look something like this:

Note that if you prefer flat segment transitions, you can use the following with Awesome Powerline Fonts installed:

POWERLEVEL9K_MODE='flat'

Which looks like this:

Option 3: Compatible Mode

This option is best if you prefer not to install additional fonts. This option will work out-of-the-box if your your terminal font supports the segment separator characters \uE0B0 (left segment separator) and \uE0B2 (right segment separator).

All you need to do to in this case is install the Powerlevel9k theme itself, as explained above, and then define the following in your ~/.zshrc:

POWERLEVEL9K_MODE='compatible'

Note that depending on your terminal font, this may still not render appropriately. This configuration should be used as a back-up.

Segment Customization

Customizing your prompt is easy! Select the segments you want to have displayed, and then assign them to either the left or right prompt. The segments that are currently available are:

  • aws - The current AWS profile, if active (more info below)
  • context - Your username and host (more info below)
  • dir - Your current working directory.
  • history - The command number for the current line.
  • rbenv - Ruby environment information (if one is active).
  • rspec_stats - Show a ratio of test classes vs code classes for RSpec.
  • status - The return code of the previous command, and status of background jobs.
  • symfony2_tests - Show a ratio of test classes vs code classes for Symfony2.
  • symfony2_version - Show the current Symfony2 version, if you are in a Symfony2-Project dir.
  • time - System time.
  • virtualenv - Your Python VirtualEnv.
  • vcs - Information about this git or hg repository (if you are in one).

To specify which segments you want, just add the following variables to your ~/.zshrc. If you don't customize this, the below configuration is the default:

POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir rbenv vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status history time)

The AWS Profile Segment

If you would like to display the current AWS profile, add the aws segment to one of the prompts, and define AWS_DEFAULT_PROFILE in your ~/.zshrc:

export AWS_DEFAULT_PROFILE=<profile_name>

The 'context' Segment

The context segment (user@host string) is conditional. This lets you enable it, but only display it if you are not your normal user or on a remote host (basically, only print it when it's likely you need it).

To use this feature, make sure the context segment is enabled in your prompt elements (it is by default), and define a DEFAULT_USER in your ~/.zshrc:

export DEFAULT_USER=<your username>

The 'time' segment

By default the time is show in 'H:M:S' format. If you want to change it, just set another format in your ~/.zshrc:

# Reversed time format
POWERLEVEL9K_TIME_FORMAT='%D{%S:%M:%H}' 

Unit Test Ratios

The symfony2_tests and rspec_tests segments both show a ratio of "real" classes vs test classes in your source code. This is just a very simple ratio, and does not show your code coverage or any sophisticated stats. All this does is count your source files and test files, and calculate the ratio between them. Just enough to give you a quick overview about the test situation of the project you are dealing with.

The 'vcs' Segment

By default, the vcs segment will provide quite a bit of information. If you would also like for it to display the current hash / changeset, simply define POWERLEVEL9K_SHOW_CHANGESET in your ~/.zshrc. If activated, it will show the first 12 characters of the changeset id. To change the amount of characters, set POWERLEVEL9K_CHANGESET_HASH_LENGTH to any value you want.

# enable the vcs segment in general
POWERLEVEL9K_SHOW_CHANGESET=true
# just show the 6 first characters of changeset
POWERLEVEL9K_CHANGESET_HASH_LENGTH=6

You can also enable an additional branch icon in your prompt by setting POWERLEVEL9K_SHOW_BRANCH_ICON to true:

# Show an icon before the branch name
POWERLEVEL9K_SHOW_BRANCH_ICON=true
Symbols

The vcs segment uses various symbols to tell you the state of your repository. These symbols depend on your installed font and selected POWERLEVEL9K_MODE from the Installation section above.

Bare Bones Normal Über explanation
↑4 ↑4 icon_outgoing4 Number of commits your repository is ahead of your remote branch
↓5 ↓5 icon_incoming5 Number of commits your repository is behind of your remote branch
⍟3 ⍟3 icon_stash3 Number of stashes, here 3.
icon_unstaged There are unstaged changes in your working copy
icon_staged There are staged changes in your working copy
? ? icon_untracked There are files in your working copy, that are unknown to your repository
icon_remote_tracking_branch The name of your branch differs from its tracking branch.
icon_bookmark A mercurial bookmark is active.
@ icon_branch_powerline Branch Icon
None None icon_commit2c3705 The current commit hash. Here "2c3705"
None None icon_git Repository is a git repository
None None icon_mercurial Repository is a Mercurial repository

Styling

You can configure the look and feel of your prompt easily with some built-in options.

Double-Lined Prompt

By default, powerlevel9k is a single-lined prompt. If you would like to have the segments display on one line, and print the command prompt below it, simply define POWERLEVEL9K_PROMPT_ON_NEWLINE in your ~/.zshrc:

POWERLEVEL9K_PROMPT_ON_NEWLINE=true

Here is what it looks like:

Light Color Theme

If you prefer to use "light" colors, simply set POWERLEVEL9K_COLOR_SCHEME to light in your ~/.zshrc, and you're all set!

POWERLEVEL9K_COLOR_SCHEME='light'

The 'light' color scheme works well for 'Solarized Light' users. Check it out:

Further color customizations

For each segment in your prompt, you can specify a foreground and background color by setting them in your ~/.zshrc. For example, to change the appearance of the time segment, you would use:

POWERLEVEL9K_TIME_FOREGROUND='red'
POWERLEVEL9K_TIME_BACKGROUND='blue'

Use the segment names from the above section Segment Customization. Some of the Segments have special color variables, as they change the colors according to some internal rules. These Segments are vcs, rspec_stats, symfony2_tests:

# General VCS color segments:
POWERLEVEL9K_VCS_FOREGROUND='blue'
POWERLEVEL9K_VCS_DARK_FOREGROUND='black'
POWERLEVEL9K_VCS_BACKGROUND='green'
# If VCS changes are detected:
POWERLEVEL9K_VCS_MODIFIED_FOREGROUND='red'
POWERLEVEL9K_VCS_MODIFIED_BACKGROUND='cyan'

# rspec_stats for good test coverage
POWERLEVEL9K_RSPEC_STATS_GOOD_FOREGROUND='blue'
POWERLEVEL9K_RSPEC_STATS_GOOD_BACKGROUND='green'
# rspec_stats for average test coverage
POWERLEVEL9K_RSPEC_STATS_AVG_FOREGROUND='black'
POWERLEVEL9K_RSPEC_STATS_AVG_BACKGROUND='cyan'
# rspec_stats for poor test coverage
POWERLEVEL9K_RSPEC_STATS_BAD_FOREGROUND='red'
POWERLEVEL9K_RSPEC_STATS_BAD_BACKGROUND='white'

# symfony2_tests for good test coverage
POWERLEVEL9K_SYMFONY2_TESTS_GOOD_FOREGROUND='blue'
POWERLEVEL9K_SYMFONY2_TESTS_GOOD_BACKGROUND='green'
# symfony2_tests for average test coverage
POWERLEVEL9K_SYMFONY2_TESTS_AVG_FOREGROUND='black'
POWERLEVEL9K_SYMFONY2_TESTS_AVG_BACKGROUND='cyan'
# symfony2_tests for poor test coverage
POWERLEVEL9K_SYMFONY2_TESTS_BAD_FOREGROUND='red'
POWERLEVEL9K_SYMFONY2_TESTS_BAD_BACKGROUND='white'

You could also use a colorcode value. Example:

POWERLEVEL9K_VCS_FOREGROUND='021' # Dark blue

For a full list of supported colors, run the spectrum_ls program in your terminal.

Troubleshooting

Here are some fixes to some common problems.

Gaps Between Segments

You can see this issue in the screenshot, below:

Thankfully, this is easy to fix. This happens if you have successfully installed Powerline fonts, but did not make a Powerline font the default font in your terminal emulator (e.g., 'terminator', 'gnome-terminal', 'konsole', etc.,).

Meta

Kudos

This theme wouldn't have happened without inspiration from the original agnoster Oh-My-ZSH theme.

Before creating this theme, I also tried jeremyFreeAgent's theme and maverick2000's theme, ZSH2000.
