beaconled 0.4.0

Your delivery compass for empowered product builders. A comprehensive toolkit for analyzing git repository statistics and development metrics.

Beacon Delivery Compass

Your delivery compass for empowered product builders. Transform engineering activity into executive-ready insights and data-driven product delivery decisions.

Quick Install

Beacon requires Python 3.10+ and Git 2.23+. We recommend installing in a virtual environment.

# Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install from PyPI
pip install beaconled

# Verify installation
beaconled --version

Quick Start

Analyze a git repository:

beaconled /path/to/repo

Generate a weekly team report:

beaconled --since 1w --until "now"

Usage Examples

Basic Analysis

# Analyze changes in the last 3 days
beaconled --since "3d"

# Date range analysis with timezone support
beaconled --since "2025-01-01" --until "2025-01-31"

# Extended analysis with team, quality, and risk metrics
beaconled --since "2w" --format extended

# Generate visual heatmaps of commit activity (requires matplotlib)
beaconled --since "1w" --format heatmap

# Disable emoji icons for plain text output
beaconled --since "1w" --no-emoji

Extended Format Features

The extended format (--format extended) includes comprehensive analytics:

• Time-Based Analytics: Velocity trends, activity heatmaps, peak periods
• Team Collaboration: Co-authorship patterns, ownership distribution
• Code Quality: Churn metrics, complexity trends, large changes
• Risk Assessment: Risk indicators, hotspot detection, stability metrics
• File Analysis:
  • Largest Changes: Identify files with most modifications (additions + deletions)
  • Frequently Changed: Track most active files during the analysis period
  • Lifecycle Tracking: Monitor file operations (added/modified/deleted/renamed)

Project Roadmap

Our development priorities and planned improvements are tracked in the Enhancement Plan. This document provides visibility into:

• Upcoming features and improvements
• Current technical debt
• Performance optimization plans
• Testing and quality assurance goals

Code Quality

Beacon is built with a strong focus on code quality and maintainability. We use pre-commit hooks to ensure consistent code quality across the project.

Pre-commit Configuration

We provide two pre-commit configurations:

1. Development Mode (.pre-commit-dev.yaml):

   • More lenient rules for local development
   • Focuses on critical issues only
   • Faster feedback loop

   # Setup development pre-commit hooks
   make dev-setup
   

2. Production Mode (.pre-commit-config.yaml):

   • Strict rules for CI/CD and production
   • Enforces all code quality standards
   • Includes all linters and formatters

   # Setup production pre-commit hooks
   make prod-setup
   

Key Quality Tools

• Type Safety: Full static type checking with mypy
• Code Style: Consistent code formatting with Black
• Linting: Code quality enforcement with Ruff
• Documentation: Comprehensive docstrings and API documentation

Development Workflow

1. During active development, use dev-setup for faster commits
2. Before pushing changes, run prod-setup to ensure all checks pass
3. Use git commit --no-verify sparingly when needed

Manual Checks

# Run type checking
mypy --ignore-missing-imports src/beaconled

# Run all code quality checks
make lint

Testing

For contributors, run the test suite with:

python run_tests.py

For detailed testing options, see our Testing Guide.
