vibe_farm 0.1.3

A Python project in a dev container.

Vibe Farm

Vibe Farm lets you write normal Python modules that have missing implementations. Mark any function with the :func:vibe_farm.farm decorator and raise :class:vibe_farm.code inside the body. The compiler reads those .py files and generates corresponding .vibe.py modules containing the actual implementation. At runtime, :func:farm hot swaps the definitions with their generated counterparts if present.

The project is designed to run inside a devcontainer, but the CLI works on any Python 3.12+ environment.

Quick Start

Install the package (the OpenAI and Anthropic client libraries are installed as dependencies) and compile a Python file that uses :func:farm:

pip install vibe-farm
vibe_farm compile examples/hello_world/hello_world.py

The resulting .vibe.py module will appear alongside the source file.

Design Decisions

Why @farm and raise code()? An early decision in the exploration is a desire for a few outcomes in the client code:

1. Make the client script directly executable. By decorating, we can hot swap with an LLM-generated implementation at runtime.
2. By raising an exception that extends NotImplementedError, the original scripts will still type check "correctly" in IDEs and with static tools such as mypy.

Project Standards & Contribution Guide

Getting Started

1. Fork the repository and clone your fork
2. Open in a devcontainer (recommended for consistent tooling)
3. Wait for the devcontainer to finish setup - all dependencies are installed automatically
4. Create a feature branch: git checkout -b feature/your-feature-name
5. Make your changes following the development practices below

Development Environment

• Devcontainer Ready: The project includes a complete devcontainer setup with all tools pre-configured
• Virtual Environment: Automatically activated in the terminal (pytest command works directly)
• Pre-configured Tools: Python 3.12+, Poetry, nox, mypy, black, pytest

Development Workflow

Making Changes

1. Write tests first - we maintain 100% test coverage
2. Format your code: Code is automatically formatted on save, or run black .
3. Run quality checks locally:

   nox -s lint    # Type checking with mypy + black formatting check
   nox -s tests   # Run full test suite with coverage
   nox            # Run all sessions (tests + lint for all Python versions)
   

4. Commit with conventional commit format:

   git commit -m "feat: add new feature description"
   git commit -m "fix: resolve issue with component"
   git commit -m "docs: update API documentation"
   

Commit Message Format

We use Conventional Commits. Valid types:

• feat: - New features
• fix: - Bug fixes
• docs: - Documentation changes
• style: - Code style changes (formatting, etc.)
• refactor: - Code refactoring
• perf: - Performance improvements
• test: - Adding or updating tests
• chore: - Maintenance tasks
• ci: - CI/CD changes
• build: - Build system changes

Pull Request Process

1. Push your branch to your fork
2. Open a Pull Request against the main branch
3. PR Title: Must follow conventional commit format (e.g., "feat: add new compiler feature")
4. Automated Checks: The following will run automatically:
   • CI Tests: Full test suite on Python 3.12
   • Code Quality: mypy type checking and black formatting validation
   • Security: Dependency vulnerability scanning
   • Coverage: Must maintain 100% test coverage
   • PR Validation: Title and commit message format checking

Continuous Integration

Automated Testing

Every pull request and push to main triggers:

• Multi-Python Testing: Tests run on Python 3.12
• Full Test Suite: All unit and integration tests via nox
• Code Quality Checks: mypy type checking and black formatting
• Security Scanning: Automated dependency vulnerability checks
• Coverage Reporting: Results uploaded to Codecov

Required Checks

Before merging, all PRs must pass:

• ✅ Tests pass on both Python versions
• ✅ 100% test coverage maintained
• ✅ No mypy type errors
• ✅ Code formatted with black
• ✅ No security vulnerabilities
• ✅ Conventional commit format
• ✅ Code review approved

Release Process

Automated Releases

Releases are automated via GitHub Actions:

1. Create a version tag:

   git tag v1.2.3
   git push origin v1.2.3
   

2. Automatic workflow:

   • Full test suite runs on both Python versions
   • Package is built with Poetry
   • Automatically published to PyPI
   • GitHub Release is created

Version Management

• Update version in pyproject.toml before tagging
• Follow Semantic Versioning
• Tag format: v1.2.3 (with 'v' prefix)

Maintenance

Automated Updates

• Dependabot: Automatically creates PRs for dependency updates weekly
• Scheduled Tests: Full test suite runs daily to catch integration issues
• Security Monitoring: Automated scanning for known vulnerabilities

Manual Tasks

• Review and merge Dependabot PRs
• Update Python version support as needed
• Maintain documentation and examples

Tooling

• Python 3.12+ (managed by devcontainer)
• Poetry for dependency management and packaging
• pytest for testing
• pytest-cov for coverage
• mypy for static type checking
• black for code formatting
• nox for automation of test and lint tasks
• ESLint, Node, npm (available in devcontainer for JS/Node interop if needed)

Development Practices

• 100% Test Coverage: All code must be covered by tests
• Type Safety: Use modern type hints for all public APIs
• Code Quality: Format with black, validate with mypy
• Documentation: Document public APIs and complex logic
• Conventional Commits: Required for all commits and PR titles

Local Development Commands

# Format code (done automatically on save in devcontainer)
black .

# Run type checking and formatting validation
nox -s lint

# Run tests with coverage (must maintain 100%)
nox -s tests

# Run everything (tests + lint for all Python versions)
nox

# Run specific Python version
nox -s tests-3.12
nox -s lint-3.12

Testing Requirements

• Unit Tests: Test individual functions and classes
• Integration Tests: Test CLI commands and workflows
• Coverage: Must maintain 100% - no exceptions
• Mock External Services: Use mocks for OpenAI/Anthropic APIs
• Fast Execution: Tests should complete quickly for CI

Code Style

• Formatting: Black with default settings (line length 88)
• Type Hints: Required for all function signatures
• Imports: Organized and minimal
• Documentation: Docstrings for public APIs using Google style

Running Tests & Linting

black .           # Format code
nox -s lint       # Type checking and lint
nox -s tests      # Run unit tests with coverage
nox               # Run all automation sessions

CLI Usage

Vibe Farm provides a small CLI with two main commands:

vibe_farm compile path/to/file.py   # generate a .vibe.py implementation
vibe_farm analyze path/to/module.py  # inspect code for vibe placeholders

Run vibe_farm --help for a full list of options.

Environment Variables

Vibe Farm automatically loads variables from a .env file if present. Set the following keys for each supported provider:

# OpenAI
OPENAI_API_KEY=your-openai-key
# Anthropic Claude
ANTHROPIC_API_KEY=your-anthropic-key

Keep the .env file outside version control (it's ignored by .gitignore).
