Powerlevel10k

Gitter

Powerlevel10k is a theme for Zsh. It emphasizes speed, flexibility and out-of-the-box experience.

Powerlevel10k

Ready to get started? See below.

To see what Powerlevel10k is about go to features.

Powerlevel9k users, go here.

See the table of contents at the bottom.

Get Started

  1. Install the recommended font. Optional but highly recommended.
  2. Install Powerlevel10k for your plugin manager.
  3. Restart Zsh.
  4. Type p10k configure if the configuration wizard doesn't start automatically.

Features

Configuration wizard

Type p10k configure to access the builtin configuration wizard right from your terminal.

Powerlevel10k Configuration Wizard

All styles except Pure are functionally equivalent. They display the same information and differ only in presentation.

Configuration wizard creates ~/.p10k.zsh based on your preferences. Additional prompt customization can be done by editing this file. It has plenty of comments to help you navigate through configuration options.

Tip: Install the recommended font before running p10k configure to unlock all prompt styles.

FAQ:

Troubleshooting:

Uncompromising performance

When you hit ENTER, the next prompt appears instantly. With Powerlevel10k there is no prompt lag. If you install Cygwin on Raspberry Pi, cd into a Linux Git repository and activate enough prompt segments to fill four prompt lines on both sides of the screen... wait, that's just crazy and no one ever does that. Probably impossible, too. The point is, Powerlevel10k prompt is always fast, no matter what you do!

Powerlevel10k Performance

Note how the effect of every command is instantly reflected by the very next prompt.

Command Prompt Indicator Meaning
timew start hack linux 🛡️ hack linux time tracking enabled in timewarrior
touch x y ?2 2 untracked files in the Git repo
rm COPYING !1 1 unstaged change in the Git repo
echo 2.7.3 >.python-version 🐍 2.7.3 the current python version in pyenv

Other Zsh themes capable of displaying the same information either produce prompt lag or print prompt that doesn't reflect the current state of the system and then refresh it later. With Powerlevel10k you get fast prompt and up-to-date information.

FAQ: Is it really fast?

Powerlevel9k compatibility

Powerlevel10k understands all Powerlevel9k configuration parameters.

Powerlevel10k Compatibility with 9k

Migration from Powerlevel9k to Powerlevel10k is a straightforward process. All your POWERLEVEL9K configuration parameters will still work. Prompt will look the same as before (almost) but it will be much faster (certainly).

FAQ:

Pure compatibility

Powerlevel10k can produce the same prompt as Pure. Type p10k configure and select Pure style.

Powerlevel10k Pure Style

You can still use Powerlevel10k features such as transient prompt or instant prompt when sporting Pure style.

To customize prompt, edit ~/.p10k.zsh. Powerlevel10k doesn't recognize Pure configuration parameters, so you'll need to use POWERLEVEL9K_COMMAND_EXECUTION_TIME_THRESHOLD=3 instead of PURE_CMD_MAX_EXEC_TIME=3, etc. All relevant parameters are in ~/.p10k.zsh. This file has plenty of comments to help you navigate through it.

FAQ: What is the best prompt style in the configuration wizard?

Instant prompt

If your ~/.zshrc loads many plugins, or perhaps just a few slow ones (for example, pyenv or nvm), you may have noticed that it takes some time for Zsh to start.

Powerlevel10k No Instant Prompt

Powerlevel10k can remove Zsh startup lag even if it's not caused by a theme.

Powerlevel10k Instant Prompt

This feature is called Instant Prompt. You need to explicitly enable it through p10k configure or manually. It does what it says on the tin -- prints prompt instantly upon Zsh startup allowing you to start typing while plugins are still loading.

Other themes increase Zsh startup lag -- some by a lot, others by a just a little. Powerlevel10k removes it outright.

FAQ: How do I enable instant prompt?

Show on command

The behavior of some commands depends on global environment. For example, kubectl run ... runs an image on the cluster defined by the current kubernetes context. If you frequently change context between "prod" and "testing", you might want to display the current context in Zsh prompt. If you do likewise for AWS, Azure and Google Cloud credentials, prompt will get pretty crowded.

Enter Show On Command. This feature makes prompt segments appear only when they are relevant to the command you are currently typing.

Powerlevel10k Show On Command

Configs created by p10k configure enable show on command for several prompt segments by default. Here's the relevant parameter for kubernetes context:

# Show prompt segment "kubecontext" only when the command you are typing
# invokes kubectl, helm, kubens, kubectx, oc, istioctl or kogito.
typeset -g POWERLEVEL9K_KUBECONTEXT_SHOW_ON_COMMAND='kubectl|helm|kubens|kubectx|oc|istioctl|kogito'

To customize when different prompt segments are shown, open ~/.p10k.zsh, search for SHOW_ON_COMMAND and either remove these parameters to display affected segments unconditionally, or change their values.

Transient prompt

When Transient Prompt is enabled through p10k configure, Powerlevel10k will trim down every prompt when accepting a command line.

Powerlevel10k Transient Prompt

Transient prompt makes it much easier to copy-paste series of commands from the terminal scrollback.

Tip: If you enable transient prompt, take advantage of two-line prompt. You'll get the benefit of extra space for typing commands without the usual drawback of reduced scrollback density. Sparse prompt (with an empty line before prompt) also works great in combination with transient prompt.

Current directory that just works

The current working directory is perhaps the most important prompt segment. Powerlevel10k goes to great length to highlight its important parts and to truncate it with the least loss of information when horizontal space gets scarce.

Powerlevel10k Directory Truncation

When the full directory doesn't fit, the leftmost segment gets truncated to its shortest unique prefix. In the screencast, ~/work becomes ~/wo. It couldn't be truncated to ~/w because it would be ambiguous (there was ~/wireguard when the session was recorded). The next segment -- projects -- turns into p as there was nothing else that started with p in ~/work/.

Directory segments are shown in one of three colors:

  • Truncated segments are bleak.
  • Important segments are bright and never truncated. These include the first and the last segment, roots of Git repositories, etc.
  • Regular segments (not truncated but can be) use in-between color.

Tip: If you copy-paste a truncated directory and hit TAB, it'll complete to the original.

Troubleshooting: Directory is difficult to see in prompt when using Rainbow style.

Extremely customizable

Powerlevel10k can be configured to look like any other Zsh theme out there.

Powerlevel10k Other Theme Emulation

Pure, Powerlevel9k and robbyrussell emulations are built-in. To emulate the appearance of other themes, you'll need to write a suitable configuration file. The best way to go about it is to run p10k configure, select the style that is the closest to your goal and then edit ~/.p10k.zsh.

The full range of Powerlevel10k appearance spans from spartan:

Powerlevel10k Spartan Style

To ridiculous extravagant:

Powerlevel10k Extravagant Style

Batteries included

Powerlevel10k comes with dozens of built-in high quality segments. When you run p10k configure and choose any style except Pure, many of these segments get enabled by default while others be manually enabled by opening ~/.p10k.zsh and uncommenting them. You can enable as many segments as you like. It won't slow down your prompt or Zsh startup.

Extensible

If there is no prompt segment that does what you need, implement your own. Powerlevel10k provides public API for defining segments that are as fast and as flexible as built-in ones.

Powerlevel10k Custom Segment

On Linux you can fetch current CPU temperature by reading /sys/class/thermal/thermal_zone0/temp. The screencast shows how to define a prompt segment to display this value. Once the segment is defined, you can use it like any other segment. All standard customization parameters will work for it out of the box.

Type p10k help segment for reference.

Tip: Prefix names of your own segments with my_ to avoid clashes with future versions of Powerlevel10k.

Troubleshooting:

For Powerlevel9k users

If you've been using Powerlevel9k before, do not remove the configuration options. Powerlevel10k will pick them up and provide you with the same prompt UI you are used to. See Powerlevel9k compatibility.

FAQ:

Troubleshooting: Extra or missing spaces in prompt compared to Powerlevel9k.

Fonts

Powerlevel10k doesn't require custom fonts but can take advantage of them if they are available. It works well with Nerd Fonts, Source Code Pro, Font Awesome, Powerline, and even the default system fonts. The full choice of style options is available only when using Nerd Fonts.

👇 Recommended font: Meslo Nerd Font patched for Powerlevel10k. 👇

Meslo Nerd Font patched for Powerlevel10k

Gorgeous monospace font designed by Jim Lyles for Bitstream, customized by the same for Apple, further customized by André Berg, and finally patched by yours truly with customized scripts originally developed by Ryan L McIntyre of Nerd Fonts. Contains all glyphs and symbols that Powerlevel10k may need. Battle-tested in dozens of different terminals on all major operating systems.

FAQ: How was the recommended font created?

Automatic font installation

If you are using iTerm2 or Termux, p10k configure can install the recommended font for you. Simply answer Yes when asked whether to install Meslo Nerd Font.

If you are using a different terminal, proceed with manual font installation. 👇

Manual font installation

Download these four ttf files:

Double-click on each file and click "Install". This will make MesloLGS NF font available to all applications on your system. Configure your terminal to use this font:

  • iTerm2: Open iTerm2 → Preferences → Profiles → Text and set Font to MesloLGS NF. Alternatively, type p10k configure and answer Yes when asked whether to install Meslo Nerd Font.
  • Apple Terminal Open Terminal → Preferences → Profiles → Text, click Change under Font and select MesloLGS NF family.
  • Hyper: Open Hyper → Edit → Preferences and change the value of fontFamily under module.exports.config to MesloLGS NF.
  • Visual Studio Code: Open File → Preferences → Settings, enter terminal.integrated.fontFamily in the search box and set the value to MesloLGS NF.
  • GNOME Terminal (the default Ubuntu terminal): Open Terminal → Preferences and click on the selected profile under Profiles. Check Custom font under Text Appearance and select MesloLGS NF Regular.
  • Konsole: Open Settings → Edit Current Profile → Appearance, click Select Font and select MesloLGS NF Regular.
  • Tilix: Open Tilix → Preferences and click on the selected profile under Profiles. Check Custom font under Text Appearance and select MesloLGS NF Regular.
  • Windows Console Host (the old thing): Click the icon in the top left corner, then Properties → Font and set Font to MesloLGS NF.
  • Windows Terminal (the new thing): Open Settings (Ctrl+,), search for fontFace and set value to MesloLGS NF for every profile.
  • Termux: Type p10k configure and answer Yes when asked whether to install Meslo Nerd Font.
  • Blink Type config, go to Appearance, tap Add a new font, tap Open Gallery, select MesloLGS NF.css, tap import and type exit in the home view to reload the font.
  • Terminus: Open Settings → Appearance and set Font to MesloLGS NF.
  • Terminator: Open Preferences using the context menu. Under Profiles select the General tab (should be selected already), uncheck Use the system fixed width font (if not already) and select MesloLGS NF Regular. Exit the Preferences dialog by clicking Close.
  • Guake: Right Click on an open terminal and open Preferences. Under Appearance tab, uncheck Use the system fixed width font (if not already) and select MesloLGS NF Regular. Exit the Preferences dialog by clicking Close.

Try it in Docker

Try Powerlevel10k in Docker. You can safely make any changes to the file system while trying out the theme. Once you exit Zsh, the image is deleted.

docker run -e TERM -e COLORTERM -it --rm alpine sh -uec '
  apk update
  apk add git zsh nano vim
  git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
  echo "source ~/powerlevel10k/powerlevel10k.zsh-theme" >>~/.zshrc
  cd ~/powerlevel10k
  exec zsh'

Tip: Install the recommended font before running the Docker command to get access to all prompt styles.

Tip: Run p10k configure while in Docker to try a different prompt style.

FAQ

How do I update Powerlevel10k?

The command to update Powerlevel10k depends on how it was installed.

Installation Update command
Manual git -C ~/powerlevel10k pull
Oh My Zsh git -C ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k pull
Prezto zprezto-update
Zim zimfw update
Antigen antigen update
Zplug zplug update
Zgen zgen update
Zplugin zplugin update
Zinit zinit update
Homebrew brew update && brew upgrade
Arch Linux yay -Syu --noconfirm --needed zsh-theme-powerlevel10k-git

IMPORTANT: Restart Zsh after updating Powerlevel10k. Do not use source ~/.zshrc.

How do I uninstall Powerlevel10k?

  1. Remove all references to "p10k" from ~/.zshrc. You might have this snippet at the top:

    if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
      source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
    fi

    And this at the bottom:

    [[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh

    These are added by the configuration wizard. Remove them.

  2. Remove all references to "powerlevel10k" from ~/.zshrc, ~/.zpreztorc and ~/.zimrc (some of these files may be missing -- this is normal). These references have been added manually by yourself when installing Powerlevel10k. Refer to the installation instructions if you need a reminder.

  3. Verify that all references to "p10k" and "powerlevel10k" are gone from ~/.zshrc, ~/.zpreztorc and ~/.zimrc.

    grep -E 'p10k|powerlevel10k' ~/.zshrc ~/.zpreztorc ~/.zimrc 2>/dev/null

    If this command produces output, there are still references to "p10k" or "powerlevel10k". You need to remove them.

  4. Delete Powerlevel10k configuration file. This file is created by the configuration wizard and may contain manual edits by yourself.

    rm -f ~/.p10k.zsh
  5. Delete Powerlevel10k source files. These files have been downloaded when you've installed Powerlevel10k. The command to delete them depends on which installation method you'd chosen. Refer to the installation instructions if you need a reminder.

    Installation Uninstall command
    Manual rm -rf ~/powerlevel10k
    Oh My Zsh rm -rf -- ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k
    Prezto n/a
    Zim zimfw uninstall
    Antigen antigen purge romkatv/powerlevel10k
    Zplug zplug clean
    Zgen zgen reset
    Zplugin zplugin delete romkatv/powerlevel10k
    Zinit zinit delete romkatv/powerlevel10k
    Homebrew brew uninstall powerlevel10k; brew untap romkatv/powerlevel10k
    Arch Linux yay -R --noconfirm zsh-theme-powerlevel10k-git
  6. Restart Zsh. Do not use source ~/.zshrc.

Where can I ask for help and report bugs?

The best way to ask for help and to report bugs is to open an issue.

Gitter is another option.

If necessary, encrypt your communication with this PGP key.

Which aspects of shell and terminal does Powerlevel10k affect?

Powerlevel10k defines prompt and nothing else. It sets prompt-related options, and parameters PS1 and RPS1.

Prompt Highlight

Everything within the highlighted areas on the screenshot is produced by Powerlevel10k. Powerlevel10k has no control over the terminal content or color outside these areas.

Powerlevel10k does not affect:

  • Terminal window title.
  • Colors used by ls.
  • Content and style of command completions.
  • Command line colors (syntax highlighting, autosuggestions, etc.).
  • Prompt parameters other than PS1 and RPS1.
  • Zsh options other than those related to prompt.

I'm using Powerlevel9k with Oh My Zsh. How do I migrate?

  1. Run this command:
# Add powerlevel10k to the list of Oh My Zsh themes.
git clone --depth=1 https://github.com/romkatv/powerlevel10k.git $ZSH_CUSTOM/themes/powerlevel10k
# Replace ZSH_THEME="powerlevel9k/powerlevel9k" with ZSH_THEME="powerlevel10k/powerlevel10k".
sed 's/powerlevel9k/powerlevel10k/g' -i ~/.zshrc
# Restart Zsh.
exec zsh
  1. Optional but highly recommended:
    1. Install the recommended font.
    2. Type p10k configure and choose your favorite prompt style.

Is it really fast?

Yes.

asciicast

Benchmark results obtained with zsh-prompt-benchmark on an Intel i9-7900X running Ubuntu 18.04 with the config from the demo.

Theme Prompt Latency
powerlevel9k/master 1046 ms
powerlevel9k/next 1005 ms
powerlevel10k 8.7 ms

Powerlevel10k is over 100 times faster than Powerlevel9k in this benchmark.

In fairness, Powerlevel9k has acceptable latency when given a spartan configuration. If all you need is the current directory without truncation or shortening, Powerlevel9k can render it for you in 17 ms. Powerlevel10k can do the same 30 times faster but it won't matter in practice because 17 ms is fast enough (the threshold where latency becomes noticeable is around 50 ms). You have to be careful with Powerlevel9k configuration as it's all too easy to make prompt frustratingly slow. Powerlevel10k, on the other hand, doesn't require trading latency for utility -- it's virtually instant with any configuration. It stays well below the 50 ms mark, leaving most of the latency budget for other plugins you might install.

How do I enable instant prompt?

See instant prompt to learn about instant prompt. This section explains how you can enable it and lists caveats that you should be aware of.

Instant prompt can be enabled either through p10k configure or by manually adding the following code snippet at the top of ~/.zshrc:

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
  source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi

It's important that you copy the lines verbatim. Don't replace source with something else, don't call zcompile, don't redirect output, etc.

When instant prompt is enabled, for the duration of Zsh initialization standard input is redirected to /dev/null and standard output with standard error are redirected to a temporary file. Once Zsh is fully initialized, standard file descriptors are restored and the content of the temporary file is printed out.

When using instant prompt, you should carefully check any output that appears on Zsh startup as it may indicate that initialization has been altered, or perhaps even broken, by instant prompt. Initialization code that may require console input, such as asking for a keyring password or for a [y/n] confirmation, must be moved above the instant prompt preamble in ~/.zshrc. Initialization code that merely prints to console but never reads from it will work correctly with instant prompt, although output that normally has colors may appear uncolored. You can either leave it be, suppress the output, or move it above the instant prompt preamble.

Here's an example of ~/.zshrc that breaks when instant prompt is enabled:

if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
  source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi

keychain id_rsa --agents ssh  # asks for password
chatty-script                 # spams to stdout even when everything is fine
# ...

Fixed version:

keychain id_rsa --agents ssh  # moved before instant prompt

# OK to perform console I/O before this point.
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
  source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi
# From this point on, until zsh is fully initialized, console input won't work and
# console output may appear uncolored.

chatty-script >/dev/null      # spam output suppressed
# ...

If POWERLEVEL9K_INSTANT_PROMPT is unset or set to verbose, Powerlevel10k will print a warning when it detects console output during initialization to bring attention to potential issues. You can silence this warning (without suppressing console output) with POWERLEVEL9K_INSTANT_PROMPT=quiet. This is recommended if some initialization code in ~/.zshrc prints to console and it's infeasible to move it above the instant prompt preamble or to suppress its output. You can completely disable instant prompt with POWERLEVEL9K_INSTANT_PROMPT=off. Do this if instant prompt breaks Zsh initialization and you don't know how to fix it.

Note: Instant prompt requires Zsh >= 5.4. It's OK to enable it even when using an older version of Zsh but it won't do anything.

What do different symbols in Git status mean?

When using Lean, Classic or Rainbow style, Git status may look like this:

feature:master ⇣42⇡42 ⇠42⇢42 *42 merge ~42 +42 !42 ?42
Symbol Meaning Source
feature current branch; replaced with #tag or @commit if not on a branch git status --ignore-submodules=dirty
master remote tracking branch; only shown if different from local branch git rev-parse --abbrev-ref --symbolic-full-name @{u}
⇣42 this many commits behind the remote git status --ignore-submodules=dirty
⇡42 this many commits ahead of the remote git status --ignore-submodules=dirty
⇠42 this many commits behind the push remote git rev-list --left-right --count HEAD...@{push}
⇢42 this many commits ahead of the push remote git rev-list --left-right --count HEAD...@{push}

+42 this many staged changes git status --ignore-submodules=dirty
!42 this many unstaged changes git status --ignore-submodules=dirty
?42 this many untracked files git status --ignore-submodules=dirty
the number of staged, unstaged or untracked files is unknown echo $POWERLEVEL9K_VCS_MAX_INDEX_SIZE_DIRTY or git config --get bash.showDirtyState

How do I change the format of Git status?

To change the format of Git status, open ~/.p10k.zsh, search for my_git_formatter and edit its source code.

Related: What do different symbols in Git status mean?

Why is Git status from $HOME/.git not displayed in prompt?

When using Lean, Classic or Rainbow style, ~/.p10k.zsh contains the following parameter:

# Don't show Git status in prompt for repositories whose workdir matches this pattern.
# For example, if set to '~', the Git repository at $HOME/.git will be ignored.
# Multiple patterns can be combined with '|': '~(|/foo)|/bar/baz/*'.
typeset -g POWERLEVEL9K_VCS_DISABLED_WORKDIR_PATTERN='~'

To see Git status for $HOME/.git in prompt, open ~/.p10k.zsh and remove POWERLEVEL9K_VCS_DISABLED_WORKDIR_PATTERN.

Why does Git status sometimes appear grey and then gets colored after a short period of time?

tl;dr: When Git status in prompt is greyed out, it means Powerlevel10k is currently computing up-to-date Git status in the background. Prompt will get automatically refreshed when this computation completes.

When your current directory is within a Git repository, Powerlevel10k computes up-to-date Git status after every command. If the repository is large, or the machine is slow, this computation can take quite a bit of time. If it takes longer than 20 milliseconds (configurable via POWERLEVEL9K_VCS_MAX_SYNC_LATENCY_SECONDS), Powerlevel10k displays the last known Git status in grey and continues to compute up-to-date Git status in the background. When the computation completes, Powerlevel10k refreshes prompt with new information, this time with colored Git status.

How do I add username and/or hostname to prompt?

When using Lean, Classic or Rainbow style, prompt shows username@hostname when you are logged in as root or via SSH. There is little value in showing username or hostname when you are logged in to your local machine as a normal user. So the absence of username@hostname in your prompt is an indication that you are working locally and that you aren't root. You can change it, however.

Open ~/.p10k.zsh. Close to the top you can see the most important parameters that define which segments are shown in your prompt. All generally useful prompt segments are listed in there. Some of them are enabled, others are commented out. One of them is of interest to you.

typeset -g POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(
  ...
  context  # user@hostname
  ...
)

Search for context to find the section in the config that lists parameters specific to this prompt segment. You should see the following lines:

# Don't show context unless running with privileges or in SSH.
# Tip: Remove the next line to always show context.
typeset -g POWERLEVEL9K_CONTEXT_{DEFAULT,SUDO}_{CONTENT,VISUAL_IDENTIFIER}_EXPANSION=

If you follow the tip and remove (or comment out) the last line, you'll always see username@hostname in prompt. You can change the format to just username, or change the color, by adjusting the values of parameters nearby. There are plenty of comments to help you navigate.

You can also move context to a different position in POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS or even to POWERLEVEL9K_LEFT_PROMPT_ELEMENTS.

Why some prompt segments appear and disappear as I'm typing?

Prompt segments can be configured to be shown only when the current command you are typing invokes a relevant tool.

# Show prompt segment "kubecontext" only when the command you are typing
# invokes kubectl, helm, kubens, kubectx, oc, istioctl or kogito.
typeset -g POWERLEVEL9K_KUBECONTEXT_SHOW_ON_COMMAND='kubectl|helm|kubens|kubectx|oc|istioctl|kogito'

Configs created by p10k configure may contain parameters of this kind. To customize when different prompt segments are shown, open ~/.p10k.zsh, search for SHOW_ON_COMMAND and either remove these parameters or change their values.

You can also define a function in ~/.zshrc to toggle the display of a prompt segment between always and on command. This is similar to kubeon/kubeoff from kube-ps1.

function kube-toggle() {
  if (( ${+POWERLEVEL9K_KUBECONTEXT_SHOW_ON_COMMAND} )); then
    unset POWERLEVEL9K_KUBECONTEXT_SHOW_ON_COMMAND
  else
    POWERLEVEL9K_KUBECONTEXT_SHOW_ON_COMMAND='kubectl|helm|kubens|kubectx|oc|istioctl|kogito'
  fi
  p10k reload
  if zle; then
    zle push-input
    zle accept-line
  fi
}

Invoke this function by typing kube-toggle. You can also bind it to a key by adding two more lines to ~/.zshrc:

zle -N kube-toggle
bindkey '^]' kube-toggle  # ctrl-] to toggle kubecontext in powerlevel10k prompt

How do I change prompt colors?

You can either change the color palette used by your terminal or set colors through Powerlevel10k configuration parameters.

Change the color palette used by your terminal

How exactly you change the terminal color palette (a.k.a. color scheme, or theme) depends on the kind of terminal you are using. Look around in terminal's settings/preferences or consult documentation.

When you change the terminal color palette, it usually affects only the first 16 colors, numbered from 0 to 15. In order to see any effect on Powerlevel10k prompt, you need to use prompt style that utilizes these low-numbered colors. Type p10k configure and select Rainbow, Lean8 colors or PureOriginal. Other styles use higher-numbered colors, so they look the same in any terminal color palette.

Set colors through Powerlevel10k configuration parameters

Open ~/.p10k.zsh, search for "color", "foreground" and "background" and change values of appropriate parameters. For example, here's how you can set the foreground of time prompt segment to bright red:

typeset -g POWERLEVEL9K_TIME_FOREGROUND=160

Colors are specified using numbers from 0 to 255. Colors from 0 to 15 look differently in different terminals. Many terminals also support customization of these colors through color palettes (a.k.a. color schemes, or themes). Colors from 16 to 255 always look the same.

Type source ~/.p10k.zsh to apply your changes to the current Zsh session.

To see how different colors look in your terminal, run the following command:

for i in {0..255}; do print -Pn "%K{$i}  %k%F{$i}${(l:3::0:)i}%f " ${${(M)$((i%6)):#3}:+$'\n'}; done

Why does Powerlevel10k spawn extra processes?

Powerlevel10k uses gitstatus as the backend behind vcs prompt; gitstatus spawns gitstatusd and zsh. See gitstatus for details. Powerlevel10k may also spawn zsh to perform computation without blocking prompt. To avoid security hazard, these background processes aren't shared by different interactive shells. They terminate automatically when the parent zsh process terminates or runs exec(3).

Are there configuration options that make Powerlevel10k slow?

No, Powerlevel10k is always fast, with any configuration you throw at it. If you have noticeable prompt latency when using Powerlevel10k, please open an issue.

Is Powerlevel10k fast to load?

Yes, provided that you are using Zsh >= 5.4.

Loading time, or time to first prompt, can be measured with the following benchmark:

time (repeat 1000 zsh -dfis <<< 'source ~/powerlevel10k/powerlevel10k.zsh-theme')

Note: This measures time to first complete prompt. Powerlevel10k can also display a limited prompt before the full-featured prompt is ready.

Running this command with ~/powerlevel10k as the current directory on the same machine as in the prompt benchmark takes 29 seconds (29 ms per invocation). This is about 6 times faster than powerlevel9k/master and 17 times faster than powerlevel9k/next.

What is the relationship between Powerlevel9k and Powerlevel10k?

Powerlevel10k was forked from Powerlevel9k in March 2019 after a week-long discussion in powerlevel9k#1170. Powerlevel9k was already a mature project with large user base and release cycle measured in months. Powerlevel10k was spun off to iterate on performance improvements and new features at much higher pace.

Powerlevel9k and Powerlevel10k are independent projects. When using one, you shouldn't install the other. Issues should be filed against the project that you actually use. There are no individuals that have commit rights in both repositories. All bug fixes and new features committed to Powerlevel9k repository get ported to Powerlevel10k.

Over time, virtually all code in Powerlevel10k has been rewritten. There is currently no meaningful overlap between the implementations of Powerlevel9k and Powerlevel10k.

Powerlevel10k is committed to maintaining backward compatibility with all configs indefinitely. This commitment covers all configuration parameters recognized by Powerlevel9k (see Powerlevel9k compatibility) and additional parameters that only Powerlevel10k understands. Names of all parameters in Powerlevel10k start with POWERLEVEL9K_ for consistency.

Does Powerlevel10k always render exactly the same prompt as Powerlevel9k given the same config?

Almost. There are a few differences.

  • By default only git vcs backend is enabled in Powerlevel10k. If you need svn and hg, add them to POWERLEVEL9K_VCS_BACKENDS. These backends aren't yet optimized in Powerlevel10k, so enabling them will make prompt very slow.
  • Powerlevel10k doesn't support POWERLEVEL9K_VCS_SHOW_SUBMODULE_DIRTY=true.
  • Powerlevel10k strives to be bug-compatible with Powerlevel9k but not when it comes to egregious bugs. If you accidentally rely on these bugs, your prompt will differ between Powerlevel9k and Powerlevel10k. Some examples:
    • Powerlevel9k ignores some options that are set after the theme is sourced while Powerlevel10k respects all options. If you see different icons in Powerlevel9k and Powerlevel10k, you've probably defined POWERLEVEL9K_MODE before sourcing the theme. This parameter gets ignored by Powerlevel9k but honored by Powerlevel10k. If you want your prompt to look in Powerlevel10k the same as in Powerlevel9k, remove POWERLEVEL9K_MODE.
    • Powerlevel9k doesn't respect ZLE_RPROMPT_INDENT. As a result, right prompt in Powerlevel10k can have an extra space at the end compared to Powerlevel9k. Set ZLE_RPROMPT_INDENT=0 if you don't want that space. More details in troubleshooting.
    • Powerlevel9k has inconsistent spacing around icons. This was fixed in Powerlevel10k. Set POWERLEVEL9K_LEGACY_ICON_SPACING=true to get the same spacing as in Powerlevel9k. More details in troubleshooting.
    • There are dozens more bugs in Powerlevel9k that don't exist in Powerlevel10k.

If you notice any other changes in prompt appearance when switching from Powerlevel9k to Powerlevel10k, please open an issue.

What is the best prompt style in the configuration wizard?

There are as many opinions on what constitutes the best prompt as there are people. It mostly comes down to personal preference. There are, however, a few hidden implications of different choices.

Pure style is an exact replication of Pure Zsh theme. It exists to ease the migration for users of this theme. Unless you are one of them, choose Lean style over Pure.

If you want to confine prompt colors to the selected terminal color palette (say, Solarized Dark), use Rainbow, Lean8 colors or PureOriginal. Other styles use fixed colors and thus look the same in any terminal color palette.

All styles except Pure have an option to use ASCII charset. Prompt will look less pretty but will render correctly with all fonts and in all locales.

If you enable transient prompt, take advantage of two-line prompt. You'll get the benefit of extra space for typing commands without the usual drawback of reduced scrollback density. Having all commands start from the same offset is also nice.

Similarly, if you enable transient prompt, sparse prompt (with an empty line before prompt) is a great choice.

If you are using vi keymap, choose prompt with prompt_char in it (shown as green in the wizard). This symbol changes depending on vi mode: , , V, for insert, command, visual and replace mode respectively. When a command fails, the symbol turns red. Lean style always has prompt_char in it. Rainbow and Classic styles have it only in the two-line configuration without left frame.

If you value horizontal space or prefer minimalist aesthetics:

  • Use a monospace font, such as the recommended font. Non-monospace fonts require extra space after icons that are larger than a single column.
  • Use Lean style. Compared to Classic and Rainbow, it saves two characters per prompt segment.
  • Disable current time and frame.
  • Use few icons. The extra icons enabled by the many icons option primarily serve decorative function. Informative icons, such as background job indicator, will be shown either way.

Note: You can run configuration wizard as many times as you like. Type p10k configure to try new prompt style.

How to make Powerlevel10k look like robbyrussell Oh My Zsh theme?

Use this config.

You can either download it, save as ~/.p10k.zsh and source ~/.p10k.zsh from ~/.zshrc, or source p10k-robbyrussell.zsh directly from your cloned powerlevel10k repository.

Can prompts for completed commands display error status for those commands instead of the commands preceding them?

No. When you hit ENTER and the command you've typed starts running, its error status isn't yet known, so it cannot be shown in prompt. When the command completes, the error status gets known but it's no longer possible to update prompt for that command. This is why the error status for every command is reflected in the next prompt.

For details, see this post on /r/zsh.

What is the minimum supported Zsh version?

Zsh 5.1 or newer should work. Fast startup requires Zsh >= 5.4.

How were these screenshots and animated gifs created?

All screenshots and animated gifs were recorded in GNOME Terminal with the recommended font and Tango Dark color palette with custom background color (#171A1B instead of #2E3436 -- twice as dark).

GNOME Terminal Color Settings

Syntax highlighting, where present, was provided by zsh-syntax-highlighting.

How was the recommended font created?

The recommended font is the product of many individuals. Its origin is Bitstream Vera Sans Mono, which has given birth to Menlo, which in turn has spawned Meslo. Finally, extra glyphs have been added to Meslo with scripts forked from Nerd Fonts. The final font is released under the terms of Apache License.

MesloLGS NF font can be recreated with the following command (requires git and docker):

git clone --depth=1 https://github.com/romkatv/nerd-fonts.git
cd nerd-fonts
./build 'Meslo/S/*'

If everything goes well, four ttf files will appear in ./out.

How to package Powerlevel10k for distribution?

It's currently neither easy nor recommended to package and distribute Powerlevel10k. There are no instructions you can follow that would allow you to easily update your package when new versions of Powerlevel10k are released. This may change in the future but not soon.

Troubleshooting

Question mark in prompt

If it looks like a regular ?, that's normal. It means you have untracked files in the current Git repository. Type git status to see these files. You can change this symbol or disable the display of untracked files altogether. Search for untracked files in ~/.p10k.zsh.

FAQ: What do different symbols in Git status mean?

You can also get a weird-looking question mark in your prompt if your terminal's font is missing some glyphs. See icons, glyphs or powerline symbols don't render.

Icons, glyphs or powerline symbols don't render

Restart your terminal, install the recommended font and run p10k configure.

Sub-pixel imperfections around powerline symbols

Powerline Prompt Imperfections

There are three imperfections on the screenshot. From left to right:

  1. A thin blue line (a sub-pixel gap) between the content of a prompt segment and the following powerline connection.
  2. Incorrect alignment of a powerline connection and the following prompt segment. The connection appears shifted to the right.
  3. A thin red line below a powerline connection. The connection appears shifted up.

Zsh themes don't have down-to-pixel control over the terminal content. Everything you see on the screen is made of monospace characters. A white powerline prompt segment is made of text on white background followed by U+E0B0 (a right-pointing triangle).

Powerline Prompt Imperfections

If Powerlevel10k prompt has imperfections around powerline symbols, you'll see exactly the same imperfections with all powerline themes (Agnoster, Powerlevel9k, Powerline, etc.)

There are several things you can try to deal with these imperfections:

  • Try the recommended font. If you are already using it, switching to another font may help but is unlikely.
  • Change terminal font size one point up or down. For example, in iTerm2 powerline prompt looks perfect at font sizes 11 and 13 but breaks down at 12.
  • Enable builtin powerline glyphs in terminal settings if your terminal supports it (iTerm2 does).
  • Change font hinting and/or anti-aliasing mode in the terminal settings.
  • Shift all text one pixel up/down/left/right if your terminal has an option to do so.
  • Try a different terminal.

A more radical solution is to switch to prompt style without background. Type p10k configure and select Lean. This style has a modern lightweight look. As a bonus, it doesn't suffer from rendering imperfections that afflict powerline-style prompt.

Error: character not in range

Type echo '\u276F'. If you get an error saying "zsh: character not in range", your locale doesn't support UTF-8. You need to fix it. If you are running Zsh over SSH, see this. If you are running Zsh locally, Google "set UTF-8 locale in your OS".

Cursor is in the wrong place

Type echo '\u276F'. If you get an error saying "zsh: character not in range", see the previous section.

If the echo command prints but the cursor is still in the wrong place, install the recommended font and run p10k configure.

If this doesn't help, add unset ZLE_RPROMPT_INDENT at the bottom of ~/.zshrc.

Still having issues? Run the following command to diagnose the problem:

() {
  emulate -L zsh
  setopt err_return no_unset
  local text
  print -rl -- 'Select a part of your prompt from the terminal window and paste it below.' ''
  read -r '?Prompt: ' text
  local -i len=${(m)#text}
  local frame="+-${(pl.$len..-.):-}-+"
  print -lr -- $frame "| $text |" $frame
}

If the prompt line aligns with the frame

+------------------------------+
| romka@adam ✓ ~/powerlevel10k |
+------------------------------+

If the output of the command is aligned for every part of your prompt (left and right), this indicates a bug in the theme or your config. Use this command to diagnose it:

print -rl -- ${(eq+)PROMPT} ${(eq+)RPROMPT}

Look for %{...%} and backslash escapes in the output. If there are any, they are the likely culprits. Open an issue if you get stuck.

If the prompt line is longer than the frame

+-----------------------------+
| romka@adam ✓ ~/powerlevel10k |
+-----------------------------+

This is usually caused by a terminal bug or misconfiguration that makes it print ambiguous-width characters as double-width instead of single width. For example, this issue.

If the prompt line is shorter than the frame and is mangled

+------------------------------+
| romka@adam ✓~/powerlevel10k |
+------------------------------+

Note that this prompt is different from the original as it's missing a space after the check mark.

This can be caused by a low-level bug in macOS. See this issue.

This can also happen if prompt contains glyphs designated as "wide" in the Unicode standard and your terminal incorrectly displays them as non-wide. Terminals suffering from this limitation include Konsole, Hyper and the integrated VSCode Terminal. The solution is to use a different terminal or remove all wide glyphs from prompt.

If the prompt line is shorter than the frame and is not mangled

+--------------------------------+
| romka@adam ✓ ~/powerlevel10k |
+--------------------------------+

This can be caused by misconfigured locale. See this issue.

Configuration wizard runs automatically every time Zsh is started

When Powerlevel10k starts, it automatically runs p10k configure if no POWERLEVEL9K_* parameters are defined. Based on your prompt style choices, the configuration wizard creates ~/.p10k.zsh with a bunch of POWERLEVEL9K_* parameters in it and adds a line to ~/.zshrc to source this file. The next time you start Zsh, the configuration wizard shouldn't run automatically. If it does, this means the evaluation of ~/.zshrc terminates prematurely before it reaches the line that sources ~/.p10k.zsh. This most often happens due to syntax errors in ~/.zshrc. These errors get hidden by the configuration wizard screen, so you don't notice them. When you exit configuration wizard, look for error messages. You can also use POWERLEVEL9K_DISABLE_CONFIGURATION_WIZARD=true zsh to start Zsh without automatically running the configuration wizard. Once you can see the errors, fix ~/.zshrc to get rid of them.

Some prompt styles are missing from the configuration wizard

If Zsh version is below 5.7.1 or COLORTERM environment variable is neither 24bit nor truecolor, configuration wizard won't offer Pure style with Snazzy color scheme. Fix: Install Zsh >= 5.7.1 and use a terminal with truecolor support. Verify with print -P '%F{#ff0000}red%f'.

If the terminal can display fewer than 256 colors, configuration wizard preselects Lean style with 8 colors. All other styles require at least 256 colors. Fix: Use a terminal with 256 color support and make sure that TERM environment variable is set correctly. Verify with print $terminfo[colors].

If there is no UTF-8 locale on the system, configuration wizard won't offer prompt styles that use Unicode characters. Fix: Install a UTF-8 locale. Verify with locale -a.

When a UTF-8 locale is available, the first few questions asked by the configuration wizard assess capabilities of the terminal font. If your answers indicate that some glyphs don't render correctly, configuration wizard won't offer prompt styles that use them. Fix: Restart your terminal and install the recommended font. Verify by running p10k configure and checking that all glyphs render correctly.

The minimum screen size at which configuration wizard can function is 55 columns by 21 lines. However, not all prompt styles are offered at such small screen size as there is simply not enough space to present them. Fix: Resize your terminal to at least 84 columns by 25 lines prior to running p10k configure. Verify with print ${COLUMNS}x${LINES}.

Cannot install the recommended font

Once you download the recommended font, you can install it just like any other font. Google "how to install fonts on your OS".

Extra or missing spaces in prompt compared to Powerlevel9k

tl;dr: Add ZLE_RPROMPT_INDENT=0 and POWERLEVEL9K_LEGACY_ICON_SPACING=true to ~/.zshrc to get the same prompt spacing as in Powerlevel9k.

When using Powerlevel10k with a Powerlevel9k config, you might get additional spaces in prompt here and there. These come in two flavors.

Extra space without background on the right side of right prompt

tl;dr: Add ZLE_RPROMPT_INDENT=0 to ~/.zshrc to get rid of that space.

From Zsh documentation:

ZLE_RPROMPT_INDENT <S>

If set, used to give the indentation between the right hand side of the right prompt in the line editor as given by RPS1 or RPROMPT and the right hand side of the screen. If not set, the value 1 is used.

Typically this will be used to set the value to 0 so that the prompt appears flush with the right hand side of the screen.

Powerlevel10k respects this parameter. If you set ZLE_RPROMPT_INDENT=1 (or leave it unset, which is the same thing as setting it to 1), you'll get an empty space to the right of right prompt. If you set ZLE_RPROMPT_INDENT=0, your prompt will go to the edge of the terminal. This is how it works in every theme except Powerlevel9k.

ZLE_RPROMPT_INDENT: Powerlevel10k vs Powerlevel9k

Powerlevel9k issue: powerlevel9k#1292. It's been fixed in the development branch of Powerlevel9k but the fix hasn't yet made it to master.

Add ZLE_RPROMPT_INDENT=0 to ~/.zshrc to get the same spacing on the right edge of prompt as in Powerlevel9k.

Note: Several versions of Zsh have bugs that get triggered when you set ZLE_RPROMPT_INDENT=0. Powerlevel10k can work around these bugs when using powerline prompt style. If you notice visual artifacts in prompt, or wrong cursor position, try removing ZLE_RPROMPT_INDENT from ~/.zshrc.

Extra or missing spaces around icons

tl;dr: Add POWERLEVEL9K_LEGACY_ICON_SPACING=true to ~/.zshrc to get the same spacing around icons as in Powerlevel9k.

Spacing around icons in Powerlevel9k is inconsistent.

ZLE_RPROMPT_INDENT: Powerlevel10k vs Powerlevel9k

This inconsistency is a constant source of annoyance, so it was fixed in Powerlevel10k. You can add POWERLEVEL9K_LEGACY_ICON_SPACING=true to ~/.zshrc to get the same spacing around icons as in Powerlevel9k.

Note: It's not a good idea to define POWERLEVEL9K_LEGACY_ICON_SPACING when using p10k configure.

Weird things happen after typing source ~/.zshrc

It's almost always a bad idea to run source ~/.zshrc, whether you are using Powerlevel10k or not. This command may result in random errors, misbehaving code and progressive slowdown of Zsh.

If you've made changes to ~/.zshrc or to files sourced by it, restart Zsh to apply them. The most reliable way to do this is to type exit and then start a new Zsh session. You can also use exec zsh. While not exactly equivalent to complete Zsh restart, this command is much more reliable than source ~/.zshrc.

Transient prompt stops working after some time

See weird things happen after typing source ~/.zshrc.

Cannot make Powerlevel10k work with my plugin manager

If the installation instructions didn't work for you, try disabling your current theme (so that you end up with no theme) and then installing Powerlevel10k manually.

  1. Disable the current theme in your framework / plugin manager.
  • oh-my-zsh: Open ~/.zshrc and remove the line that sets ZSH_THEME. It might look like this: ZSH_THEME="powerlevel9k/powerlevel9k".
  • zplug: Open ~/.zshrc and remove the zplug command that refers to your current theme. For example, if you are currently using Powerlevel9k, look for zplug bhilburn/powerlevel9k, use:powerlevel9k.zsh-theme.
  • prezto: Open ~/.zpreztorc and put zstyle :prezto:module:prompt theme off in it. Remove any other command that sets theme such as zstyle :prezto:module:prompt theme powerlevel9k.
  • antigen: Open ~/.zshrc and remove the line that sets antigen theme. It might look like this: antigen theme powerlevel9k/powerlevel9k.
  1. Install Powerlevel10k manually.
git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
echo 'source ~/powerlevel10k/powerlevel10k.zsh-theme' >>! ~/.zshrc

This method of installation won't make anything slower or otherwise sub-par.

Directory is difficult to see in prompt when using Rainbow style

In Rainbow style the current working directory is shown with bright white text on blue background. The white is fixed and always looks the same but the appearance of "blue" is defined by your terminal color palette. If it's very light, it may be difficult to see white text on it.

There are several ways to fix this.

  • Type p10k configure and choose a more readable prompt style.
  • Change terminal color palette. Try Tango Dark or Solarized Dark, or change just the "blue" color.
  • Change directory background and/or foreground color. The parameters you are looking for are called POWERLEVEL9K_DIR_BACKGROUND, POWERLEVEL9K_DIR_FOREGROUND, POWERLEVEL9K_DIR_SHORTENED_FOREGROUND, POWERLEVEL9K_DIR_ANCHOR_FOREGROUND and POWERLEVEL9K_DIR_ANCHOR_BOLD. You can find them in in ~/.p10k.zsh.

Horrific mess when resizing terminal window

When you resize terminal window horizontally back and forth a few times, you might see this ugly picture.

Powerlevel10k Resizing Mess

tl;dr: This is a bug in Zsh that isn't specific to Powerlevel10k. See mitigation.

Zsh bug

This issue is caused by a bug in Zsh that gets triggered when the vertical distance between the start of the current prompt and the cursor (henceforth VD) changes when the terminal window is resized. This bug is not specific to Powerlevel10k.

When a terminal window gets shrunk horizontally, there are two ways for a terminal to handle long lines that no longer fit: reflow or truncate.

Terminal content before shrinking:

Terminal Content Before Shrinking

Terminal reflows text when shrinking:

Terminal Reflows Text When Shrinking

Terminal truncates text when shrinking:

Terminal Truncates Text When Shrinking

Reflowing strategy can change the height of terminal content. If such content happens to be between the start of the current prompt and the cursor, Zsh will print prompt on the wrong line. Truncation strategy never changes the height of terminal content, so it doesn't trigger this bug in Zsh.

Let's see how the bug plays out in slow motion. We'll start by launching zsh -df and pasting the following code:

function pause() { read -s }
functions -M pause 0

reset
print -l {1..3}
setopt prompt_subst
PROMPT=$'${$((pause()))+}left>${(pl.$((COLUMNS-12))..-.)}<right\n> '

When PROMPT gets expanded, it calls pause to let us observe the state of the terminal. Here's the initial state:

Zsh Resizing Bug 1

Zsh keeps track of the cursor position relative to the start of the current prompt. In this case it knows that the cursor is one line below. When we shrink the terminal window, it looks like this:

Zsh Resizing Bug 2

At this point the terminal sends SIGWINCH to Zsh to notify it about changes in the terminal dimensions. Note that this signal is sent after the content of the terminal has been reflown.

When Zsh receives SIGWINCH, it attempts to erase the current prompt and print it anew. It goes to the position where it thinks the current prompt is -- one line above the cursor (!) -- erases all terminal content that follows and prints reexpanded prompt there. However, after resizing prompt is no longer one line above the cursor. It's two lines above! Zsh ends up printing new prompt one line too low.

Zsh Resizing Bug 3

In this case we ended up with unwanted junk content because VD has increased. When you make terminal window wider, VD can also decrease, which would result in the new prompt being printed higher than intended, potentially erasing useful content in the process.

Here are a few more examples where shrinking terminal window increased VD.

Simple one-line left prompt with right prompt. No prompt_subst. Note that the cursor is below the prompt line (hit ESC-ENTER to get it there).

Zsh Prompt That Breaks on Terminal Shrinking 1

Simple one-line left prompt. No prompt_subst, no right prompt. Here VD is bound to increase upon terminal shrinking due to the command line wrapping around.

Zsh Prompt That Breaks on Terminal Shrinking 2

Zsh patch

The bug described above has been fixed in this branch. The idea behind the fix is to use sc (save cursor) terminal capability before printing prompt and rc (restore cursor) to move cursor back to the same position when prompt needs to be refreshed.

Note: The patch doesn't work on Alacritty. On the plus side, it doesn't make things worse.

There are two alternative approaches to fixing the bug that may seem to work at first glance but in fact don't:

  • Instead of sc, use u7 terminal capability to query the current cursor position and then cup to go back to it. This doesn't work because the absolute position of the start of the current prompt changes when text gets reflown.
  • Recompute VD based on new terminal dimensions before attempting to refresh prompt. This doesn't work because Zsh doesn't know whether terminal reflows text or truncates it. If Zsh could somehow know that the terminal reflows text, this approach still wouldn't work on terminals that continuously reflow text and rapid-fire SIGWINCH when the window is being resized. In such environment real terminal dimensions go out of sync with what Zsh thinks the dimensions are.

There is no ETA for the patch making its way into upstream Zsh. See discussion.

Mitigation

There are a few mitigation options for this issue.

  • Apply the patch and rebuild Zsh from source. It won't help if you are using Alacritty.
  • Disable text reflowing on window resize in terminal settings. If your terminal doesn't have this setting, try a different terminal.
  • Avoid long lines between the start of prompt and cursor.
    1. Disable ruler with POWERLEVEL9K_SHOW_RULER=false.
    2. Disable prompt connection with POWERLEVEL9K_MULTILINE_FIRST_PROMPT_GAP_CHAR=' '.
    3. Disable right frame with POWERLEVEL9K_MULTILINE_FIRST_PROMPT_SUFFIX= and POWERLEVEL9K_MULTILINE_NEWLINE_PROMPT_SUFFIX= and POWERLEVEL9K_MULTILINE_LAST_PROMPT_SUFFIX=.
    4. Remove all elements from POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS. Right prompt on the last prompt line will cause resizing issues only when the cursor is below it. This isn't very common, so you might want to keep some elements in POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS provided that none of them are succeeded by newline.

When using Konsole with a non-monospace font, icons may be cut off on the right side. Here "non-monospace" refers to any font with glyphs wider than a single column, or wider than two columns for glyphs designated as "wide" in the Unicode standard.

The last line on the screenshot shows a cut off Arch Linux logo.

There are several mitigation options for this issue.

  1. Use a different terminal. Konsole is the only terminal that exhibits this behavior.
  2. Use a monospace font.
  3. Manually add an extra space after the icon that gets cut off. For example, if the content of os_icon prompt segment gets cut off, open ~/.p10k.zsh, search for POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION and change it as follows:
typeset -g POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION='${P9K_CONTENT} '  # extra space at the end
  1. Use a different icon that is monospace. For example, if Arch Linux logo gets cut off, add the following parameter to ~/.p10k.zsh:
typeset -g POWERLEVEL9K_LINUX_ARCH_ICON='Arch'  # plain "Arch" in place of a logo
  1. Disable the display of the icon that gets cut off. For example, if the content of os_icon prompt segment gets cut off, open ~/.p10k.zsh and remove os_icon from POWERLEVEL9K_LEFT_PROMPT_ELEMENTS and POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS.

Note: Non-monospace fonts are not officially supported by Konsole.

Arch Linux Logo with a dot

Some fonts have this incorrect dotted icon in bold typeface. There are two ways to fix this issue.

  1. Use a font with a correct Arch Linux logo in bold typeface. For example, the recommended Powerlevel10k font.
  2. Display the icon in regular (non-bold) typeface. To do this, open ~/.p10k.zsh, search for POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION and remove %B from its value.
typeset -g POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION='${P9K_CONTENT}'  # not bold
