• ✨ Add features - Pick up a feature from the roadmap

Good First Issues

New to the project? Look for issues labeled good first issue.

Development Setup

Option 1: Automated Setup (Recommended)

# Fork and clone the repository
git clone https://github.com/YOUR-USERNAME/vocalinux.git
cd vocalinux

# Install in development mode (includes all dev dependencies)
./install.sh --dev

This will:

1. Install all system dependencies
2. Create a Python virtual environment
3. Install the package in editable mode (-e)
4. Install all dev dependencies (pytest, black, isort, flake8)
5. Run the test suite automatically

Option 2: Manual Setup

1. Fork and clone:

   git clone https://github.com/YOUR-USERNAME/vocalinux.git
   cd vocalinux
   

2. Install system dependencies:

   # Ubuntu
   sudo apt update
   sudo apt install -y python3-pip python3-gi python3-gi-cairo \
       gir1.2-gtk-3.0 libgirepository1.0-dev \
       python3-dev portaudio19-dev python3-venv xdotool
   
   # Debian 11/12
   sudo apt install -y python3-pip python3-gi python3-gi-cairo \
       gir1.2-gtk-3.0 libgirepository1.0-dev libcairo2-dev \
       python3-dev portaudio19-dev python3-venv xdotool
   
   # Debian 13+
   sudo apt install -y python3-pip python3-gi python3-gi-cairo \
       gir1.2-gtk-3.0 libgirepository-2.0-dev libcairo2-dev \
       python3-dev portaudio19-dev python3-venv xdotool
   
   # For appindicator (system tray icon):
   # On older Ubuntu:
   sudo apt install -y gir1.2-appindicator3-0.1
   # On Debian 11+ or newer Ubuntu:
   sudo apt install -y gir1.2-ayatanaappindicator3-0.1
   

3. Set up Python environment:

   python3 -m venv venv --system-site-packages
   source venv/bin/activate
   pip install --upgrade pip setuptools wheel
   pip install -e ".[dev]"
   

4. Run the application:

   source venv/bin/activate
   vocalinux --debug
   

5. (Optional) Install pre-commit hooks:

   pre-commit install
   

   Note: Pre-commit hooks are optional. The CI pipeline runs the same checks, so you can skip this if you prefer faster local commits.

Making Changes

Branching Strategy

# Create a feature branch from main
git checkout main
git pull origin main
git checkout -b feature/your-feature-name

# Or for bug fixes
git checkout -b fix/issue-description

Branch naming conventions:

• feature/ - New features
• fix/ - Bug fixes
• docs/ - Documentation updates
• refactor/ - Code refactoring
• test/ - Test additions/updates

Code Style

We use automated tools to ensure consistent code style:

• Black - Code formatting (line length: 100)
• isort - Import sorting (black-compatible profile)
• flake8 - Linting

# Format your code
black src/ tests/
isort src/ tests/

# Check for issues
flake8 src/ tests/

Pre-commit hooks will run these automatically before each commit.

Key Files for Common Tasks

Task	Files
Add voice command	src/vocalinux/speech_recognition/command_processor.py
UI changes	src/vocalinux/ui/*.py
Speech recognition	src/vocalinux/speech_recognition/recognition_manager.py
Text injection	src/vocalinux/text_injection/text_injector.py
Settings	src/vocalinux/ui/config_manager.py, settings_dialog.py

Testing

Running Tests

# Activate virtual environment
source venv/bin/activate

# Run all tests
pytest

# Run with coverage
pytest --cov=src --cov-report=html

# Run specific test file
pytest tests/test_command_processor.py

# Run with verbose output
pytest -v

Writing Tests

• Place tests in the tests/ directory
• Name test files as test_*.py
• Name test functions as test_*
• Aim for at least 80% coverage for new code
• Use pytest-mock for mocking

Example test:

def test_command_processor_new_line(mocker):
    """Test that 'new line' command returns correct action."""
    processor = CommandProcessor()
    result = processor.process("new line")
    assert result.action == "new_line"

Testing Remote API

Vocalinux supports offloading speech recognition to a remote server. To test this feature locally without a real server, use the mock test server:

# Start the test server (default: port 8080)
python scripts/test_remote_server.py

# Custom port
python scripts/test_remote_server.py --port 9000

# Simulate processing delay (useful for testing timeouts)
python scripts/test_remote_server.py --delay 2

The test server supports both API formats:

• whisper.cpp: http://localhost:8080/inference
• OpenAI-compatible: http://localhost:8080/v1/audio/transcriptions

To test in Vocalinux:

1. Start the test server
2. Open Vocalinux Settings → Speech Engine (sidebar)
3. Select Remote API from the engine dropdown
4. Set Server URL to http://localhost:8080
5. Choose API Endpoint format (whisper.cpp or OpenAI)
6. Click Test Connection - should show "✓ Connected!"
7. Toggle voice recognition and speak - mock transcriptions will be injected

Stop the server: Press Ctrl+C in the terminal where it's running.

Release Process

Releases are managed through GitHub tags and the release workflow.
