powerlevel9k Theme for Oh-My-Zsh

This is a theme for Oh-My-Zsh. This theme 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.

In addition to looking amazing, this theme actually provides a lot of useful information in configurable prompt segments.

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
  • 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 are some screenshots of powerlevel9k with default settings:

Installation

There are two things you need to make this theme work correctly: Powerline fonts, and the theme itself.

Install Powerline Fonts

First, you need to install Powerline Fonts. You can find the installation instructions here. 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.

Install Powerlevel9k

To install this theme, clone this repository into your Oh-My-Zsh 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"

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.
  • 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 dir segment

The dir segment shows the current working directory. You can limit the output to a certain length:

# Limit to the last two folders
POWERLEVEL9K_SHORTEN_DIR_LENGTH=2

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_LENTH to any value you want. Example:

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

The vcs segment uses various symbols to tell you the state of your repository:

  • ↑4 - The number of commits your repository is ahead of your remote branch
  • ↓5 - The number of commits your repository is behind of your remote branch
  • ⍟3 - The number of stashes, here 3.
  • ● - There are unstaged changes in your working copy
  • ✚ - There are staged changes in your working copy
  • ? - There are files in your working copy, that are unknown to your repository
  • → - The name of your branch differs from its tracking branch.
  • ☿ - A mercurial bookmark is active.

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.,).
