powerlevel9k Theme for ZSH

Powerlevel9k is a theme for ZSH which uses Powerline Fonts. It can be used with vanilla ZSH, Oh-My-Zsh, or Prezto, and can also be installed using antigen.

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

There are a number of Powerline ZSH themes available, now. The developers of this theme focus on four primary goals:

1. Give users a great out-of-the-box configuration with no additional configuration required.
2. Make customization easy for users who do want to tweak their prompt.
3. Provide useful segments that you can enable to make your prompt even more effective and helpful. We have prompt segments for everything from unit test coverage to your AWS instance.
4. Optimize the code for execution speed as much as possible. A snappy terminal is a happy terminal.

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

Installation

There are two installation steps to go from a lame terminal to a "Power Level 9000" terminal. Once you are done, you can optionally customize your prompt.

Installation Instructions

1. Install the Powerlevel9k Theme
2. Install Powerline-Patched Fonts

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

Customization

Customizing Prompt Segments

Customizing your prompt is easy! Select the segments you want to have displayed, and then assign them to either the left or right prompt by adding 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)

Available Prompt Segments

The segments that are currently available are:

• aws - The current AWS profile, if active.
• context - Your username and host.
• dir - Your current working directory.
• history - The command number for the current line.
• ip - Shows the current IP address.
• load - Your machines 5 minute load average and free RAM.
• node_version - Show the version number of the installed Node.js.
• os_icon - Display a nice little icon, depending on your operating system.
• php_version - Show the current PHP version.
• 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.
• symphony2_tests - Show a ratio of test classes vs code classes for Symfony2.
• symphony2_version - Show the current Symfony2 version, if you are in a Symfony2-Project dir.
• time - System time.
• vi_mode- Vi editing mode (NORMAL|INSERT).
• virtualenv - Your Python VirtualEnv.
• vcs - Information about this git or hg repository (if you are in one).

aws

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>

context

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>

dir

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

To change the way how the current working directory is truncated, just set:

# truncate the middle part
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_middle"
# truncate from right, leaving the first X characters untouched
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
# default behaviour is to truncate whole directories

In each case you have to specify the length you want to shorten the directory to. So in some cases POWERLEVEL9K_SHORTEN_DIR_LENGTH means characters, in others whole directories.

ip

This segment shows you your current internal IP address. It tries to examine all currently used network interfaces and prints the first address it finds. In the case that this is not the right IP address you can specify the correct network interface by setting:

POWERLEVEL9K_IP_INTERFACE="eth0"

rspec_stats

See Unit Test Ratios, below.

status

This segment shows the return code of the last command, and the presence of any background jobs. By default, this segment will always print, but you can customize it to only print if there is an error or a forked job by setting the following variable in your ~/.zshrc.

POWERLEVEL9K_STATUS_VERBOSE=false

symphony2_tests

See Unit Test Ratios, below.

time

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

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

If you are using an "Awesome Powerline Font", you can add a time symbol to this segment, as well:

# Output time, date, and a symbol from the "Awesome Powerline Font" set
POWERLEVEL9K_TIME_FORMAT="%D{%H:%M:%S \uE868  %d.%m.%y}"

vcs

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 disable the branch icon in your prompt by setting POWERLEVEL9K_HIDE_BRANCH_ICON to true:

# Hide the branch icon
POWERLEVEL9K_HIDE_BRANCH_ICON=true

vcs 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.

Compatible	Powerline	Awesome Powerline	Explanation
↑4	↑4	4	Number of commits your repository is ahead of your remote branch
↓5	↓5	5	Number of commits your repository is behind of your remote branch
⍟3	⍟3	3	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.
@			Branch Icon
None	None	2c3705	The current commit hash. Here "2c3705"
None	None		Repository is a git repository
None	None		Repository is a Mercurial repository

vi_mode

This Segment shows the current mode of your ZSH. If you want to use your ZSH in VI-Mode, you need to configure it separately in your ~/.zshrc:

# VI-Mode
# general activation
bindkey -v

# set some nice hotkeys
bindkey '^P' up-history
bindkey '^N' down-history
bindkey '^?' backward-delete-char
bindkey '^h' backward-delete-char
bindkey '^w' backward-kill-word
bindkey '^r' history-incremental-search-backward

# make it more responsive
export KEYTIMEOUT=1

Unit Test Ratios

The symfony2_tests and rspec_stats 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.

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:

You can customize the icons used to draw the multiline prompt by setting the following variables in your ~/.zshrc:

POWERLEVEL9K_MULTILINE_FIRST_PROMPT_PREFIX="↱"
POWERLEVEL9K_MULTILINE_SECOND_PROMPT_PREFIX="↳ "

Disable Right Prompt

If you do not want a right prompt, you can disable it by setting:

POWERLEVEL9K_DISABLE_RPROMPT=true

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:

Icon Customization

Each icon used can be customized too by specifying a variable named like the icon and prefixed with 'POWERLEVEL9K'. If you want to use another icon as segment separators, you can easily do that:

POWERLEVEL9K_LEFT_SEGMENT_SEPARATOR=$'\uE0B1'
POWERLEVEL9K_RIGHT_SEGMENT_SEPARATOR=$'\uE0B3'

You could get a list of all icons defined in random colors, by adding the special segment icons_test to your prompt:

POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(icons_test)

This special prompt does not work on the right side, as it would be too long, and ZSH hides it automatically. Also have in mind, that the output depends on your POWERLEVEL9K_MODE settings.

You can change any icon by setting a environment variable. To get a full list of icons just type get_icon_names in your terminal.

Segment Color Customization

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

POWERLEVEL9K_TIME_FOREGROUND='red'
POWERLEVEL9K_TIME_BACKGROUND='blue'

Note that you can 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.

Special Segment Colors

Some segments have additional color options if you want to customize the look of your prompt even further. These Segments are context, vcs, rspec_stats, symfony2_tests:

# Customizing `context` colors for root and non-root users
POWERLEVEL9K_CONTEXT_DEFAULT_BACKGROUND="green"
POWERLEVEL9K_CONTEXT_DEFAULT_FOREGROUND="cyan"
