Powerlevel10k

Powerlevel10k is a theme for ZSH. It's a backward-compatible fork of Powerlevel9k with lower latency and better prompt responsiveness.

If you like the looks of Powerlevel9k but feeling frustrated by its slow prompt, simply replace your powerlevel9k theme with powerlevel10k and enjoy responsive shell like it's 80's again!

Powerlevel10k uses the same configuration options as Powerlevel9k and produces the same results. It's simply faster. There is no catch.

If you are on Linux or WSL, consider enabling gitstatus plugin for massive performance improvement in the vcs/prompt segment.

Installation & Configuration

For installation and configuration instructions see Powerlevel9k. Everything in there applies to Powerlevel10k as well. Follow the official installation guide, make sure everything works and you like the way prompt looks. Then simply replace file powerlevel9k.zsh-theme with the one from Powerlevel10k (link). Or replace the whole powerlevel9k directory to gain the ability to git pull updates in the future. Once you restart zsh, your prompt will be faster.

# Assuming oh-my-zsh at the standard location. Adjust to your circumstances.
rm -rf ~/.oh-my-zsh/custom/themes/powerlevel9k
git clone git@github.com:romkatv/powerlevel10k.git ~/.oh-my-zsh/custom/themes/powerlevel9k

Do not load both Powerlevel9k and Powerlevel10k themes at the same time. Variable name clashes will cause mayhem. Source either one or the other. Consider Powerlevel10k a patched fork of Powerlevel9k, which it is.

How fast is it?

Powerlevel10k with gitstatus renders prompt about 10 times faster than powerlevel9k/master (stable version) and about 4 times faster than powerlevel9k/next (beta version). Powerlevel10k is faster than Powerlevel9k even without gitstatus but the difference isn't as dramatic.

Here's are benchmark results obtained with zsh-prompt-benchmark on Intel i9-7900X running Ubuntu 18.04.

Theme	/	~/testrepo	~/nerd-fonts	~/linux
powerlevel9k/master	135 ms	207 ms	234 ms	326 ms
powerlevel9k/next	47 ms	101 ms	122 ms	213 ms
powerlevel10k w/ vcs_info	24 ms	82 ms	104 ms	197 ms
powerlevel10k w/ gitstatus	11 ms	14 ms	31 ms	76 ms
naked zsh	1 ms	1 ms	1 ms	1 ms

Columns define the current directory where the prompt was rendered.

/ -- root directory, not a git repo.
~/testrepo -- a tiny git repo.
~/nerd-fonts -- nerd-fonts git repo with 4k files.
~/linux -- linux git repo. Huge.

Here's how the prompt looked like:

Configuration that was used during benchmarking:

POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(dir_writable dir vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status background_jobs time custom_rprompt)

POWERLEVEL9K_MODE=nerdfont-complete
POWERLEVEL9K_PROMPT_ON_NEWLINE=true
POWERLEVEL9K_CUSTOM_RPROMPT=custom_rprompt
POWERLEVEL9K_ROOT_ICON=\\uF09CPOWERLEVEL9K_TIME_ICON=\\uF017
POWERLEVEL9K_CUSTOM_RPROMPT_ICON=\\uF005
POWERLEVEL9K_TIME_BACKGROUND=magenta
POWERLEVEL9K_CUSTOM_RPROMPT_BACKGROUND=blue
POWERLEVEL9K_STATUS_OK_BACKGROUND=grey53
POWERLEVEL9K_BACKGROUND_JOBS_BACKGROUND=orange1
POWERLEVEL9K_BACKGROUND_JOBS_FOREGROUND=black

# Powerlevel10k extension to enable gitstatus. Has no effect on Powerlevel9k.
POWERLEVEL9K_VCS_STATUS_COMMAND=gitstatus_query_dir

function custom_rprompt() echo -E "hello world"

What's the catch?

Really, there is no catch. It's literally the same prompt with the same flexibility configuration format as Powerlevel9k. But much faster.
