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.
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:
- Give users a great out-of-the-box configuration with no additional configuration required.
- Make customization easy for users who do want to tweak their prompt.
- 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.
- Optimize the code for execution speed as much as possible. A snappy terminal is a happy terminal.
Here is a detailed screenshot showing powerlevel9k in action, with default settings.

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.
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. 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
gitorhgrepository (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.

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.
