🛠️ Advanced Usage

Preview Your Statusline

Test your statusline before restarting Claude Code:

cc-statusline preview .claude/statusline.sh

What preview does:

1. 📄 Loads your actual statusline script
2. 🧪 Runs it with realistic mock data
3. 📊 Shows exactly what the output will look like
4. ⚡ Reports performance metrics and functionality

Installation Safety Features (v1.2.4+)

• 🔒 Safe Updates - Never overwrites existing statuslines without confirmation
• 🛡️ Settings Protection - Preserves your existing settings.json configurations
• ⚠️ Conflict Detection - Warns when other statuslines are configured
• ✅ Smart Defaults - Project-level installation by default for safety

Custom Installation

# Generate to custom location
cc-statusline init --output ./my-statusline.sh

# Skip auto-installation (manual setup)
cc-statusline init --no-install

# Global installation for convenience
npm install -g @chongdashu/cc-statusline

🔧 How It Works

How It Works

1. 🎯 Configuration - Two questions configure your preferences
2. 🏗️ Generation - Creates optimized bash script tailored to your needs
3. ⚙️ Installation - Integrates with Claude Code settings
4. 🔄 Updates - Connects to ccusage for live usage statistics

Technical Architecture

• ⚡ Bash-First - Native shell execution for maximum speed
• 🎨 Claude Code Optimized - Forces colors for Claude Code terminals (respects NO_COLOR)
• 🌍 Environment Respect - Honors NO_COLOR and other terminal conventions
• 📦 Zero Dependencies - Self-contained script with graceful fallbacks
• 🔒 Secure - No network requests except ccusage integration

📋 Requirements

✅ Required (You Already Have These!)

• Claude Code - The tool you're already using
• jq - JSON processing (pre-installed on most systems)

🎁 Optional Enhancements

• git - For branch display (you probably have this)
• ccusage - For usage stats (works via npx - no install needed)

Quick Compatibility Check

command -v jq && echo "✅ Ready to go!"

📂 File Structure

After installation, you'll have a clean setup:

.claude/
├── statusline.sh    # 🎯 Your generated statusline script
└── settings.json    # ⚙️ Auto-updated Claude Code configuration

Manual Configuration (Backup Plan)

If auto-configuration fails, simply add this to .claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": ".claude/statusline.sh",
    "padding": 0
  }
}

🔧 Troubleshooting

🚫 Statusline Not Showing

1. Restart Claude Code after installation
2. Verify settings - Check .claude/settings.json contains the configuration above
3. Check permissions - Ensure script is executable: chmod +x .claude/statusline.sh

🐌 Performance Issues

• Test performance: cc-statusline preview .claude/statusline.sh
• Optimize features: Disable heavy features if execution > 500ms
• Disable ccusage: Remove usage tracking if not needed

🧩 Missing Features

• Install jq: brew install jq (macOS) or apt install jq (Ubuntu)
• ccusage setup: Works automatically via npx ccusage@latest
• Git not found: Install git for branch display
• Context not showing: Ensure you're in an active Claude Code session with context usage
• Colors not working: Check that NO_COLOR environment variable is not set

🧪 Testing

Locking Mechanism Tests

The ccusage integration includes a robust file-based locking mechanism to prevent concurrent process spawning. Test this functionality:

Single Test:

echo '{}' | ./test/test-statusline-with-lock.sh

Concurrent Test:

./test/test-concurrent-locking.sh

Manual Concurrent Test:

# Spawn 10 concurrent processes
for i in {1..10}; do 
  echo '{}' | ./test/test-statusline-with-lock.sh & 
done

Expected Behavior:

• ✅ Only 1 process runs ccusage at a time
• ✅ Other processes skip gracefully (no pile-up)
• ✅ Lock files are properly cleaned up
• ✅ No hanging processes remain

Verification Commands:

# Check for stale locks
ls /tmp/ccusage_statusline.* 2>/dev/null || echo "✅ No locks remain"

# Monitor running processes
ps aux | grep ccusage | grep -v grep
