⚡ Claude Powerline Rust

Ultra-fast, feature-rich statusline for Claude Code with real-time usage tracking

A blazingly fast Rust replacement for the original TypeScript Claude powerline, delivering 8.4x better performance (150ms vs 1.26s) with complete feature parity and enhanced functionality.

✨ Features

📊 Real-time Usage Tracking

Today's Spending: Live cost tracking across all Claude conversations
5-Hour Block Quota: Weighted token usage with intelligent reset timing
Context Remaining: Shows available conversation context (not used!)
Session Metrics: Current conversation cost and token usage

🎨 Rich Visual Experience

5 Beautiful Themes: dark, light, nord, tokyo-night, rose-pine
2 Display Styles: minimal (clean) or powerline (with separators)
True Color Support: 24-bit RGB with 8-bit fallback
Smart Color Detection: Adapts to terminal capabilities

⚡ Performance & Reliability

SIMD-Accelerated JSON: Zero-copy parsing with simd-json
Memory-Mapped I/O: Efficient file access with memmap2
Parallel Processing: Multi-threaded data aggregation with rayon
Global Deduplication: Consistent data across all Claude projects

🔧 Smart Integration

Auto-Discovery: Finds Claude projects across ~/.claude/ and ~/.config/claude/

🚀 Installation

Prerequisites

Rust 1.70+ (install via rustup)
Claude Code (for integration)

From Source

# Clone the repository
git clone https://github.com/owloops/claude-powerline-rust.git
cd claude-powerline-rust

# Build with maximum optimization
cargo build --release

# Install system-wide (Linux/macOS)
sudo cp target/release/claude-powerline /usr/local/bin/

# Install user-local (Windows)
copy target\release\claude-powerline.exe %USERPROFILE%\.local\bin\

Installation for Windooze Monkeyes

Windows users can get this shit working with a few simple steps. Yes, it WILL correctly parse Claude files on Windows because:

Path Discovery: Automatically finds Claude data in %APPDATA%\Claude and %USERPROFILE%\.claude
Path Separators: Rust's PathBuf handles both / and \ automatically
File Parsing: JSONL files are identical format across all platforms
Environment Variables: Uses ; separator instead of , for Windows paths

PowerShell Installation (Recommended)

# Create local bin directory if it doesn't exist
New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.local\bin"

# Download and extract (replace with actual Windows release when available)
Invoke-WebRequest -Uri "https://github.com/david-strejc/claude-powerline-rust/releases/download/v1.0.0/claude-powerline-v1.0.0-windows-x86_64.zip" -OutFile "claude-powerline.zip"
Expand-Archive -Path "claude-powerline.zip" -DestinationPath "$env:USERPROFILE\.local\bin"

# Add to PATH (add this to your PowerShell profile)
$env:PATH += ";$env:USERPROFILE\.local\bin"

# Test the installation
claude-powerline --theme tokyo-night --style powerline --basename

CMD Installation (For Old School Monkeyes)

REM Create directory
mkdir "%USERPROFILE%\.local\bin"

REM Download manually from GitHub releases, then:
copy claude-powerline.exe "%USERPROFILE%\.local\bin\"

REM Add to PATH permanently
setx PATH "%PATH%;%USERPROFILE%\.local\bin"

REM Test it
claude-powerline --help

Claude Code Integration (Windows)

Edit %USERPROFILE%\.claude\settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "claude-powerline.exe --theme tokyo-night --style powerline --basename"
  }
}

Windows Terminal Setup

Add to your Windows Terminal profile settings:

{
  "profiles": {
    "defaults": {
      "commandline": "powershell.exe",
      "startingDirectory": "%USERPROFILE%",
      "environment": {
        "CLAUDE_POWERLINE_THEME": "tokyo-night",
        "CLAUDE_POWERLINE_STYLE": "powerline"
      }
    }
  }
}

Note: Windows build will be available in future releases. For now, you'll need to cross-compile from Linux or build from source on Windows.
