Contributing Guide

Welcome! This guide helps you contribute to the Tibber Prices integration.

Getting Started​

Prerequisites​

  • Git
  • VS Code with Remote Containers extension
  • Docker Desktop

Fork and Clone​

  1. Fork the repository on GitHub
  2. Clone your fork: 
    git clone https://github.com/YOUR_USERNAME/hass.tibber_prices.git
    cd hass.tibber_prices
  3. Open in VS Code
  4. Click "Reopen in Container" when prompted

The DevContainer will set up everything automatically.

Development Workflow​

1. Create a Branch​

git checkout -b feature/your-feature-name
# or
git checkout -b fix/issue-123-description

Branch naming:

  • feature/ - New features
  • fix/ - Bug fixes
  • docs/ - Documentation only
  • refactor/ - Code restructuring
  • test/ - Test improvements

2. Make Changes​

Edit code, following Coding Guidelines.

Run checks frequently:

./scripts/type-check  # Pyright type checking
./scripts/lint        # Ruff linting (auto-fix)
./scripts/test        # Run tests

3. Test Locally​

./scripts/develop     # Start HA with integration loaded

Access at http://localhost:8123

4. Write Tests​

Add tests in /tests/ for new features:

@pytest.mark.unit
async def test_your_feature(hass, coordinator):
    """Test your new feature."""
    # Arrange
    coordinator.data = {...}

    # Act
    result = your_function(coordinator.data)

    # Assert
    assert result == expected_value

Run your test:

./scripts/test tests/test_your_feature.py -v

5. Commit Changes​

Follow Conventional Commits:

git add .
git commit -m "feat(sensors): add volatility trend sensor

Add new sensor showing 3-hour volatility trend direction.
Includes attributes with historical volatility data.

Impact: Users can predict when prices will stabilize or continue fluctuating."

Commit types:

  • feat: - New feature
  • fix: - Bug fix
  • docs: - Documentation
  • refactor: - Code restructuring
  • test: - Test changes
  • chore: - Maintenance

Add scope when relevant:

  • feat(sensors): - Sensor platform
  • fix(coordinator): - Data coordinator
  • docs(user): - User documentation

6. Push and Create PR​

git push origin your-branch-name

Then open Pull Request on GitHub.

Pull Request Guidelines​

PR Template​

Title: Short, descriptive (50 chars max)

Description should include:

## What
Brief description of changes

## Why
Problem being solved or feature rationale

## How
Implementation approach

## Testing
- [ ] Manual testing in Home Assistant
- [ ] Unit tests added/updated
- [ ] Type checking passes
- [ ] Linting passes

## Breaking Changes
(If any - describe migration path)

## Related Issues
Closes #123

PR Checklist​

Before submitting:

  • Code follows Coding Guidelines
  • All tests pass (./scripts/test)
  • Type checking passes (./scripts/type-check)
  • Linting passes (./scripts/lint-check)
  • Documentation updated (if needed)
  • AGENTS.md updated (if patterns changed)
  • Commit messages follow Conventional Commits

Review Process​

  1. Automated checks run (CI/CD)
  2. Maintainer review (usually within 3 days)
  3. Address feedback if requested
  4. Approval → Maintainer merges

Code Review Tips​

What Reviewers Look For​

✅ Good:

  • Clear, self-explanatory code
  • Appropriate comments for complex logic
  • Tests covering edge cases
  • Type hints on all functions
  • Follows existing patterns

❌ Avoid:

  • Large PRs (>500 lines) - split into smaller ones
  • Mixing unrelated changes
  • Missing tests for new features
  • Breaking changes without migration path
  • Copy-pasted code (refactor into shared functions)

Responding to Feedback​

  • Don't take it personally - we're improving code together
  • Ask questions if feedback unclear
  • Push additional commits to address comments
  • Mark conversations as resolved when fixed

Finding Issues to Work On​

Good first issues are labeled:

  • good first issue - Beginner-friendly
  • help wanted - Maintainers welcome contributions
  • documentation - Docs improvements

Comment on issue before starting work to avoid duplicates.

Communication​

  • GitHub Issues - Bug reports, feature requests
  • Pull Requests - Code discussion
  • Discussions - General questions, ideas

Be respectful, constructive, and patient. We're all volunteers! 🙏
