Powerlevel9k

## Powerlevel9k is deprecated and now unmaintained. Please use Powerlevel10k!

Powerlevel9k is a theme for ZSH which uses Powerline Fonts. It can be used with vanilla ZSH or ZSH frameworks such as Oh-My-Zsh, Prezto, Antigen, and many others.

Get more out of your terminal. Be a badass. Impress everyone in 'Screenshot Your Desktop' threads. Use powerlevel9k.

You can check out some other users' configurations in our wiki: Show Off Your Config.

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.

Powerlevel9k can be used to create both very useful and beautiful terminal environments:

Installation

There are two installation steps to go from a vanilla terminal to a PL9k terminal. Once you are done, you can optionally customize your prompt.

Installation Instructions

1. Install the Powerlevel9k Theme
2. Install Powerline 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.

Prompt Customization

Be sure to check out the wiki page on the additional prompt customization options, including color and icon settings: Stylizing Your Prompt

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.

The table above shows the default values, so if you wanted to set these variables manually, you would put the following in your ~/.zshrc:

POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status root_indicator background_jobs history time)

anaconda

This segment shows your active anaconda environment. It relies on either the CONDA_ENV_PATH or the CONDA_PREFIX (depending on the conda version) environment variable to be set which happens when you properly source activate an environment.

Special configuration variables:

Additionally the following segment specific parameters can be used to customize it: POWERLEVEL9K_PYTHON_ICON, POWERLEVEL9K_ANACONDA_BACKGROUND, and POWERLEVEL9K_ANACONDA_FOREGROUND.

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:

background_jobs

battery

The default settings for this segment will display your current battery status (fails gracefully on systems without a battery). It is supported on both OSX and Linux (note that it requires acpi on Linux).

Note that you can modify the _FOREGROUND color without affecting the icon color.

You can also change the battery icon automatically depending on the battery level. This will override the default battery icon. In order to do this, you need to define the POWERLEVEL9k_BATTERY_STAGES variable.

Powerlevel9k will use each index of the string or array as a stage to indicate battery charge level, progressing from left to right. You can provide any number of stages. The setting below, for example, provides 8 stages for Powerlevel9k to use.

POWERLEVEL9K_BATTERY_STAGES="▁▂▃▄▅▆▇█"

If you require extra spacing after the icon, you will have to set it as an array, since spaces in the string will be used as one of the stages and you will get a missing icon. To do this, declare the variable as follows:

POWERLEVEL9K_BATTERY_STAGES=($'\u2581 ' $'\u2582 ' $'\u2583 ' $'\u2584 ' $'\u2585 ' $'\u2586 ' $'\u2587 ' $'\u2588 ')

Using the array syntax, you can create stages comprised of multiple characters. The below setting provides 40 battery stages.

POWERLEVEL9K_BATTERY_STAGES=(
   $'▏    ▏' $'▎    ▏' $'▍    ▏' $'▌    ▏' $'▋    ▏' $'▊    ▏' $'▉    ▏' $'█    ▏'
   $'█▏   ▏' $'█▎   ▏' $'█▍   ▏' $'█▌   ▏' $'█▋   ▏' $'█▊   ▏' $'█▉   ▏' $'██   ▏'
   $'██   ▏' $'██▎  ▏' $'██▍  ▏' $'██▌  ▏' $'██▋  ▏' $'██▊  ▏' $'██▉  ▏' $'███  ▏'
   $'███  ▏' $'███▎ ▏' $'███▍ ▏' $'███▌ ▏' $'███▋ ▏' $'███▊ ▏' $'███▉ ▏' $'████ ▏'
   $'████ ▏' $'████▎▏' $'████▍▏' $'████▌▏' $'████▋▏' $'████▊▏' $'████▉▏' $'█████▏' )

You can also change the background of the segment automatically depending on the battery level. This will override the following variables: POWERLEVEL9K_BATTERY_CHARGING, POWERLEVEL9K_BATTERY_CHARGED, POWERLEVEL9K_BATTERY_DISCONNECTED, and POWERLEVEL9K_BATTERY_LOW_COLOR. In order to do this, define a color array, from low to high, as shown below:

POWERLEVEL9K_BATTERY_LEVEL_BACKGROUND=(red1 orangered1 darkorange orange1 gold1 yellow1 yellow2 greenyellow chartreuse1 chartreuse2 green1)

As with the battery stages, you can use any number of colors and Powerlevel9k will automatically use all of them appropriately.

Some example settings:

chruby

This segment shows the version of Ruby being used when using chruby to change your current Ruby stack.

It uses $RUBY_ENGINE and $RUBY_VERSION as set by chruby.

commandexecutiontime

Display the time the previous command took to execute if the time is above POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD. The time is formatted to be "human readable", and so scales the units based on the length of execution time. If you want more precision, just set the POWERLEVEL9K_COMMAND_EXECUTION_TIME_PRECISION field.

custom_command

The custom_... segment allows you to turn the output of a custom command into a prompt segment. As an example, if you wanted to create a custom segment to display your WiFi signal strength, you might define a custom segment called custom_wifi_signal like this:

POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)
POWERLEVEL9K_CUSTOM_WIFI_SIGNAL="echo signal: \$(nmcli device wifi | grep yes | awk '{print \$8}')"
POWERLEVEL9K_CUSTOM_WIFI_SIGNAL_BACKGROUND="blue"
POWERLEVEL9K_CUSTOM_WIFI_SIGNAL_FOREGROUND="yellow"

If you prefer, you can also define the function in your .zshrc rather than putting it in-line with the variable export, as shown above. Just don't forget to invoke your function from your segment! Example code that achieves the same result as the above:

zsh_wifi_signal(){
    local signal=$(nmcli device wifi | grep yes | awk '{print $8}')
    local color='%F{yellow}'
    [[ $signal -gt 75 ]] && color='%F{green}'
    [[ $signal -lt 50 ]] && color='%F{red}'
    echo -n "%{$color%}\uf230  $signal%{%f%}" # \uf230 is 
}

POWERLEVEL9K_CUSTOM_WIFI_SIGNAL="zsh_wifi_signal"
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_wifi_signal)

The command, above, gives you the wireless signal segment shown below:

You can define as many custom segments as you wish. If you think you have a segment that others would find useful, please consider upstreaming it to the main theme distribution so that everyone can use it!

context

The context segment (user@host string) is conditional. By default, it will only print if you are not your 'normal' user (including if you are root), or if you are SSH'd to a remote host. SUDO and REMOTE_SUDO states are also available to show whether the current user or remote user has superuser privileges.

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.

You can customize the context segment. For example, you can make it to print the full hostname by setting

POWERLEVEL9K_CONTEXT_TEMPLATE="%n@`hostname -f`"

You can set the POWERLEVEL9K_CONTEXT_HOST_DEPTH variable to change how the hostname is displayed. See ZSH Manual for details. The default is set to %m which will show the hostname up to the first ‘.’ You can set it to %{N}m where N is an integer to show that many segments of system hostname. Setting N to a negative integer will show that many segments from the end of the hostname.

This segment can have different states. They might help you to visualize your different privileges. Read more about styling with states here.

date

The date segment shows the current system date.

dir

The dir segment shows the current working directory. When using the "Awesome Powerline" fonts, there are additional glyphs, as well:

Compatible	Powerline	Awesome Powerline	Situation
None	None		At the root of your home folder
None	None		Within a subfolder of your home directory
None	None		Outside of your home folder
None	None	⚙	Within the /etc directory

To turn off these icons you could set these variables to an empty string.

POWERLEVEL9K_HOME_ICON=''
POWERLEVEL9K_HOME_SUB_ICON=''
POWERLEVEL9K_FOLDER_ICON=''
POWERLEVEL9K_ETC_ICON=''

You can limit the output to a certain length by truncating long paths. Customizations available are:

For example, if you wanted the truncation behavior of the fish shell, which truncates /usr/share/plasma to /u/s/plasma, you would use the following:

POWERLEVEL9K_SHORTEN_DIR_LENGTH=1
POWERLEVEL9K_SHORTEN_DELIMITER=""
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"

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.

The truncate_with_package_name strategy gives your directory path relative to the root of your project. For example, if you have a project inside $HOME/projects/my-project with a package.json that looks like:

{
  "name": "my-cool-project"
}

The path shown would be my-cool-project. If you navigate to $HOME/projects/my-project/src, then the path shown would be my-cool-project/src. Please note that this currently looks for .git directory to determine the root of the project.

If you want to customize the directory separator, you could set:

# Double quotes are important here!
POWERLEVEL9K_DIR_PATH_SEPARATOR="%F{red} $(print_icon 'LEFT_SUBSEGMENT_SEPARATOR') %F{black}"

To omit the first character (usually a slash that gets replaced if you set POWERLEVEL9K_DIR_PATH_SEPARATOR), you could set POWERLEVEL9K_DIR_OMIT_FIRST_CHARACTER=true.

You can also customize the leading tilde character when you are in $HOME using:

# Double quotes are important here!
POWERLEVEL9K_HOME_FOLDER_ABBREVIATION="%F{red} $(print_icon 'HOME_ICON') %F{black}"

You can also configure the dir segment to show when you are in a directory without write permissions, using the variable below.

If you want to customize the last directory of the path, you can now set POWERLEVEL9K_DIR_PATH_HIGHLIGHT_FOREGROUND to a custom color and/or POWERLEVEL9K_DIR_PATH_HIGHLIGHT_BOLD=true to display that part in bold.

You can also color the separator separately by setting the color using POWERLEVEL9K_DIR_PATH_SEPARATOR_FOREGROUND.

disk_usage

The disk_usage segment will show the usage level of the partition that your current working directory resides in. It can be configured with the following variables.

host

The host segment will print the hostname.

You can set the POWERLEVEL9K_HOST_TEMPLATE variable to change how the hostname is displayed. See (ZSH Manual)[http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Login-information] for details. The default is set to %m which will show the hostname up to the first .. You can set it to %{N}m where N is an integer to show that many segments of system hostname. Setting N to a negative integer will show that many segments from the end of the hostname.

POWERLEVEL9K_HOST_TEMPLATE="%2m"

By default, LOCAL hosts will show the host icon and remote hosts will show the SSH icon. You can override them by setting

POWERLEVEL9K_HOST_ICON="\uF109 "
POWERLEVEL9K_SSH_ICON="\uF489 "

ip

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

vpn_ip

This segment tries to extract the VPN related IP addresses from nmcli, based on the NIC type:

public_ip

This segment will display your public IP address. There are several methods of obtaining this information and by default it will try all of them starting with the most efficient. You can also specify which method you would like it to use. The methods available are dig using opendns, curl, or wget. The host used for wget and curl is http://ident.me by default but can be set to another host if you prefer.

If you activate a VPN, the icon for this segment will change to the defined VPN icon.

The publicip segment will attempt to update your public IP address every 5 minutes by default(also configurable by the user). If you lose connection your cached IP address will be displayed until your timeout expires at which point every time your prompt is generated a new attempt will be made. Until an IP is successfully pulled the value of $POWERLEVEL9KPUBLICIPNONE will be displayed for this segment. If this value is empty(the default)and $POWERLEVEL9KPUBLICIP_FILE is empty the segment will not be displayed.

load

Displays one of your load averages with appropriate state coloring. The thresholds are:

• 0.7 * NUM_CORES <: critical
• 0.5 * NUM_CORES <: warning
• less: normal

newline

Puts a newline in your prompt so you can continue using segments on the next line. This allows you to use segments on both lines, unlike POWERLEVEL9K_PROMPT_ON_NEWLINE, which simply separates segments from the prompt itself.

This only works on the left side. On the right side it does nothing.

nodeenv

Shows the currently used nodeenv. To avoid Nodeenvs activate command from interfering with Powerlevel9k, you should set NODE_VIRTUAL_ENV_DISABLE_PROMPT=1 in your ~/.zshrc.

rbenv

This segment shows the version of Ruby being used when using rbenv to change your current Ruby stack.

It figures out the version being used by taking the output of the rbenv version-name command.

• If rbenv is not in $PATH, nothing will be shown.
• By default, if the current local Ruby version is the same as the global Ruby version, nothing will be shown. See the configuration variable, below, to modify this behavior.

pyenv

This segment shows the version of Python being used when using pyenv to change your current Python stack.

The PYENV_VERSION environment variable will be used if specified. Otherwise it figures out the version being used by taking the output of the pyenv version-name command.

• If pyenv is not in $PATH, nothing will be shown.
• If the current Python version is the same as the global Python version, nothing will be shown.

rspec_stats

See Unit Test Ratios, below.

status

This segment shows the return code of the last command.

ram

symfony2_tests

See Unit Test Ratios, below.

time

As an example, if you wanted a reversed time format, you would use this:

# 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}"

user

The user segment will print the username.

You can also override the icons by setting:

POWERLEVEL9K_USER_ICON="\uF415" # 
POWERLEVEL9K_ROOT_ICON="#"
POWERLEVEL9K_SUDO_ICON=$'\uF09C' # 

vcs

By default, the vcs segment will provide quite a bit of information. Further customization is provided via:

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

vcs truncation

You can limit the branch name to a certain length by truncating long names. Customizations available are:

For example, if you want to truncate 1234-super_super_long_branch_name to 1234-.. and don't do it with development:

POWERLEVEL9K_VCS_SHORTEN_LENGTH=4
POWERLEVEL9K_VCS_SHORTEN_MIN_LENGTH=11
POWERLEVEL9K_VCS_SHORTEN_STRATEGY="truncate_from_right"
POWERLEVEL9K_VCS_SHORTEN_DELIMITER=".."

vi_mode

This segment shows ZSH's current input mode. Note that this is only useful if you are using the ZSH Line Editor (VI mode). You can enable this either by .zshrc configuration or using a plugin, like Oh-My-Zsh's vi-mode plugin.

To hide the segment entirely when in INSERT mode, set POWERLEVEL9K_VI_INSERT_MODE_STRING=''

virtualenv

This segment shows your Python VirtualEnv. To avoid VirtualEnvs activate command from interfering with Powerlevel9k, you should set VIRTUAL_ENV_DISABLE_PROMPT=1 in your ~/.zshrc.

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.

Disabling / Enabling Powerlevel9k

You can disable P9k and return to a very basic prompt at any time simply by calling:

$ prompt_powerlevel9k_teardown

You can then re-enable it by calling:

$ prompt_powerlevel9k_setup
