# Updating Vocalinux

This guide explains how to update Vocalinux to the latest version.

## What's New in v0.6.1-beta

### ✨ New Features

- **Interactive Backend Selection**: When installing whisper.cpp, you can now choose between GPU (Vulkan/CUDA) or CPU backend with intelligent hardware detection
- **Enhanced Welcome Message**: Completely redesigned end-of-installation message showing what was installed, testing instructions, and voice command examples

### 🔧 Improvements

- **Version Consistency**: Install commands now download install.sh directly from the release tag, ensuring perfect version matching

- **Better GPU Support**: Fixed Vulkan development library detection and installation

### 🐛 Bug Fixes

- **Fixed TTY Check**: Interactive mode now works correctly with `--interactive` flag
- **Auto-install Git**: Installer now automatically installs git if not present
- **GPU Installation**: Fixed pip command execution for GPU backend installation
- **Bash Arithmetic**: Fixed issues with `((var++))` and `set -e` compatibility

### 📚 Documentation

- Updated all install commands to use tag-based URLs
- Improved error messages with correct install instructions
- Better inline help in install script

## Quick Update (Recommended)

### If You Installed via curl (One-liner)

Simply re-run the installation command with the new version tag:

```bash
curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.1-beta/install.sh | bash
```

The installer will:
- Update your existing installation
- Preserve your configuration and models
- Install any new dependencies

> **Note**: The installer automatically detects and updates existing installations.

### If You Installed from Source

```bash
cd vocalinux
git fetch origin
git checkout v0.6.1-beta
./install.sh
```

Or to always get the latest main branch:

```bash
cd vocalinux
git pull origin main
./install.sh
```

## Detailed Update Methods

### Method 1: Reinstall via Installer (Easiest)

The installer handles everything automatically:

```bash
# From the repo (if you have it cloned)
cd vocalinux
./install.sh --tag=v0.4.1-alpha

# Or via curl (for any installation)
curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.1-beta/install.sh | bash
```

**What gets preserved:**
- Your configuration at `~/.config/vocalinux/`
- Your speech models at `~/.local/share/vocalinux/models/`
- Your custom settings and preferences

### Method 2: Manual Update (Advanced)

If you prefer manual control over the update process:

```bash
# 1. Navigate to your vocalinux directory
cd vocalinux

# 2. Pull the latest changes
git fetch origin
git checkout v0.6.1-beta

# 3. Activate your virtual environment
source venv/bin/activate

# 4. Update the package
pip install --upgrade .

# 5. Exit and restart
exit
vocalinux
```

## Checking Your Current Version

To see which version you have installed:

```bash
# Check the package version
python3 -c "import vocalinux; print(vocalinux.version.__version__)"

# Or check from the repo
git describe --tags
```

## Troubleshooting

### Update Won't Install

**Symptom:** Installation fails during update

**Solution:** Run the uninstaller first, then reinstall:

```bash
# Keep your config and models
./uninstall.sh --keep-config --keep-data

# Reinstall
curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.1-beta/install.sh | bash
```

### Old Version Still Running

**Symptom:** After update, old version is still active

**Solution:** Fully exit and restart:

```bash
# Kill any running instances
pkill -f vocalinux

# Start fresh
vocalinux
```

### Dependencies Changed

**Symptom:** New version has different system dependencies

**Solution:** The installer handles this, but if you see errors:

```bash
sudo apt update
sudo apt install -y python3-gi python3-gi-cairo gir1.2-gtk-3.0
```

## Automatic Updates (Coming Soon)

We're working on an in-app update mechanism. For now, please use the manual update methods above.

```bash
# Check latest release
curl -s https://api.github.com/repos/jatinkrmalik/vocalinux/releases/latest | grep "tag_name"
```
