# Powerlevel10k — Instant-Prompt Zsh Theme with Deep Git Integration

## Quick Use
```bash
git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
echo 'source ~/powerlevel10k/powerlevel10k.zsh-theme' >> ~/.zshrc
exec zsh
p10k configure
```

## Introduction
Powerlevel10k is a Zsh theme that emphasizes speed, flexibility, and out-of-the-box experience. It eliminates prompt rendering lag through Instant Prompt, which displays the prompt immediately while Zsh initializes in the background, and uses gitstatus for async repository information.

## What Powerlevel10k Does
- Renders a full-featured prompt in under 1ms using Instant Prompt technology
- Displays Git status (branch, staged, unstaged, untracked) without blocking input
- Shows context-aware segments: language versions, AWS profile, kubectl context
- Provides a configuration wizard (p10k configure) for interactive customization
- Supports Powerlevel9k configuration syntax as a drop-in replacement

## Architecture Overview
Powerlevel10k splits prompt rendering into synchronous and asynchronous phases. Instant Prompt caches the previous prompt output and displays it before .zshrc finishes loading. The gitstatus binary (a custom C implementation of git-status) runs in a background process and communicates results via a Unix socket, updating the prompt without blocking.

## Self-Hosting & Configuration
- Install via Oh My Zsh, Zinit, Zplug, or manual git clone
- Run p10k configure for the interactive setup wizard with style previews
- Edit ~/.p10k.zsh for segment ordering, colors, and icons
- Requires a Nerd Font for full icon rendering (MesloLGS NF recommended)
- Supports transient prompt to collapse previous prompts for cleaner scrollback

## Key Features
- Instant Prompt eliminates Zsh startup delay regardless of plugin count
- Async gitstatus handles repositories with millions of files without lag
- Pure style option mimics the minimal sindresorhus/pure prompt aesthetic
- 40+ prompt segments for cloud, language, VCS, and system information
- Works in TTY, SSH, tmux, and screen with automatic feature degradation

## Comparison with Similar Tools
- **Starship** — cross-shell Rust binary with less Zsh-specific optimization
- **Pure** — minimal async prompt without the segment ecosystem
- **Oh My Posh** — cross-shell but requires external binary and config file
- **Spaceship** — Zsh-native but noticeably slower on large Git repos

## FAQ
**Q: Does Powerlevel10k work with Oh My Zsh?**
A: Yes, set ZSH_THEME="powerlevel10k/powerlevel10k" in .zshrc after cloning to the custom themes directory.

**Q: Why do I see diamond or square symbols instead of icons?**
A: Install MesloLGS NF font and configure your terminal to use it.

**Q: Can I use Powerlevel10k over SSH?**
A: Yes, Instant Prompt works over SSH. Install the Nerd Font on your local terminal.

**Q: How does Instant Prompt work technically?**
A: It serializes the last prompt to a cache file and prints it before sourcing .zshrc, giving the illusion of zero startup time.
