Development Setup

Development Setup

Note: These docs need review.

This guide covers setting up VoiceMode for development, including building from source, configuring your IDE, and contributing to the project.

Prerequisites

• Python 3.10 or higher
• Git
• UV package manager (recommended) or pip
• Node.js 18+ (for frontend development)

Setting Up UV

UV is a fast Python package manager written in Rust. It's the recommended tool for VoiceMode development:

# Install UV
curl -LsSf https://astral.sh/uv/install.sh | sh

# Or using pip
pip install uv

Cloning the Repository

For contributors: Fork the repo first at https://github.com/mbailey/voicemode, then clone your fork:

# Clone your fork (replace YOUR-USERNAME)
git clone https://github.com/YOUR-USERNAME/voicemode
cd voicemode

# Install in development mode
uv tool install -e .

Development Workflow

Running from Source

Building the Package

# Build the package
uv build

# This creates:
# dist/voice_mode-X.Y.Z-py3-none-any.whl
# dist/voice_mode-X.Y.Z.tar.gz

# Test the built package
uvx --from dist/voice_mode-*.whl voicemode

Running Tests

# Run all tests
pytest

# Run with coverage
pytest --cov=voice_mode

# Run specific test file
pytest tests/test_converse.py

# Run with verbose output
pytest -v

Using Local Services

For development without API keys:

# Or manually
voicemode whisper install
voicemode kokoro install

# Or manually
voicemode whisper start
voicemode kokoro start

Common Development Tasks

Adding a New Tool

1. Create tool file in voice_mode/tools/
2. Implement tool class with MCP decorators
3. Add tests in tests/tools/
4. Update documentation

Modifying Configuration

1. Update voice_mode/config.py
2. Add environment variable to docs
3. Update tests for new config
4. Add to example .env files

Updating Dependencies

# Add a new dependency
uv add requests

# Add development dependency
uv add --dev pytest-mock

# Update all dependencies
uv sync

Debugging

Enable Debug Mode

export VOICEMODE_DEBUG=true
export VOICEMODE_LOG_LEVEL=debug

Debug Output Locations

• Logs: ~/.voicemode/logs/
• Audio files: ~/.voicemode/debug/
• Event logs: ~/.voicemode/events.log

Common Debug Commands

# Check service status
voicemode whisper status
voicemode kokoro status

Testing

Unit Tests

# Run all unit tests
pytest tests/unit/

# Run with markers
pytest -m "not integration"

Integration Tests

# Run integration tests
pytest tests/integration/

# Run specific service tests
pytest tests/integration/test_whisper.py

Manual Testing

# Test voice conversation
voicemode converse --debug

# Test with different providers
VOICEMODE_TTS_BASE_URLS=http://localhost:8880/v1 voicemode converse

Contributing

Code Style

We use Black for formatting and Ruff for linting:

# Format code
black voice_mode tests

# Run linter
ruff check voice_mode tests

# Fix linting issues
ruff check --fix voice_mode tests

Pre-commit Hooks

# Install pre-commit
pip install pre-commit

# Install hooks
pre-commit install

# Run manually
pre-commit run --all-files

Commit Messages

Follow conventional commits:

• feat: New feature
