🔄 Update Command

Keep your installation up-to-date automatically.

The update command works for all installation methods (npm/pip/cargo/manual) by directly downloading and replacing the binary from GitHub releases.

Basic Usage

# Check for updates
vct update --check

# Interactive update with confirmation
vct update

# Force update - always downloads latest version (even if already up-to-date)
vct update --force

✨ How It Works

1. Check Latest Version: Fetches the latest release from GitHub API
2. Compare Versions: Compares current version with the latest available (skipped with --force)
3. Download Binary: Downloads the appropriate binary for your platform (Linux/macOS/Windows)
4. Smart Replacement:
   • Linux/macOS: Automatically replaces the binary (backs up old version to .old)
   • Windows: Downloads as .new and creates a batch script for safe replacement

🔄 Force Update Mode

The --force flag bypasses version checking and always downloads the latest release:

# Force reinstall the latest version (useful for corrupted installations)
vct update --force

Use cases:

• Reinstall after corrupted binary
• Force download latest release without version check
• Troubleshooting installation issues

Only fails if: No binary is found for your platform (OS/architecture)

🎯 Works for All Installation Methods

Whether you installed via npm, pip, cargo, or manually, vct update will work the same way:

$ vct update --check
🔍 Checking for updates...
📌 Current version: 0.1.6
📌 Latest version:  v0.1.7

🆕 New version available: v0.1.7

💡 To update, run:
vct update

Why does this work? All installation methods (npm/pip/cargo/manual) use the same pre-compiled binaries from GitHub releases. The update command simply downloads the latest binary and replaces your current installation.

Platform Support

The update command automatically detects your platform and downloads the correct archive:

• Linux: vibe_coding_tracker-v{version}-linux-x64-gnu.tar.gz, vibe_coding_tracker-v{version}-linux-arm64-gnu.tar.gz
• macOS: vibe_coding_tracker-v{version}-macos-x64.tar.gz, vibe_coding_tracker-v{version}-macos-arm64.tar.gz
• Windows: vibe_coding_tracker-v{version}-windows-x64.zip, vibe_coding_tracker-v{version}-windows-arm64.zip

Windows Update Process

On Windows, the binary cannot be replaced while running. The update command:

1. Downloads the new version as vct.new
2. Creates an update script (update_vct.bat)
3. Displays instructions to complete the update

Run the batch script after closing the application to finish the update.

💡 Smart Pricing System

How It Works

1. Automatic Updates: Fetches pricing from LiteLLM daily
2. Smart Caching: Stores pricing in ~/.vibe_coding_tracker/ for 24 hours
3. Fuzzy Matching: Finds best match even for custom model names
4. Always Accurate: Ensures you get the latest pricing

Model Matching

Priority Order:

1. ✅ Exact Match: claude-sonnet-4 → claude-sonnet-4
2. 🔄 Normalized: claude-sonnet-4-20250514 → claude-sonnet-4
3. 🔍 Substring: custom-gpt-4 → gpt-4
4. 🎯 Fuzzy (AI-powered): Uses Jaro-Winkler similarity (70% threshold)
5. 💵 Fallback: Shows $0.00 if no match found

Cost Calculation

Total Cost = (Input Tokens × Input Cost) +
             (Output Tokens × Output Cost) +
             (Cache Read × Cache Read Cost) +
             (Cache Creation × Cache Creation Cost)
