This is a complete rewrite and reorganization of the Elixir Stopwatch project, transforming it from a simple script into a professional, feature-rich application with proper project structure. Major Changes: - Converted from single script (stopwatch.exs) to full Mix project - Created modular architecture with separation of concerns - Added comprehensive test suite with high coverage - Enhanced functionality with pause/resume and lap timing - Implemented multiple time display formats - Created rich, color-coded CLI interface with real-time display - Added complete documentation and examples New Modules: - Stopwatch: Core module with state management, lap tracking, and history - Stopwatch.Formatter: Flexible time formatting utilities - Stopwatch.CLI: Interactive command-line interface Features Added: - High-precision timing using monotonic time - Pause/resume functionality with accurate time accounting - Lap timing with statistics (fastest, slowest, average) - Multiple display formats (short, long, compact, verbose) - Event history tracking - Comprehensive error handling - Escript configuration for standalone executable Documentation: - Detailed README with usage examples and API documentation - CHANGELOG for version tracking - CONTRIBUTING guidelines for developers - Inline documentation with @doc and @moduledoc - Type specifications for better IDE support Testing: - Comprehensive test suite for core stopwatch functionality - Formatter tests with multiple scenarios - Test helper setup Project Infrastructure: - Proper mix.exs configuration - Enhanced .gitignore for Mix projects - MIT License maintained Breaking Changes: - Replaced simple script with Mix project structure - New command-line interface (backward incompatible) - Programmatic API completely redesigned
This commit adds extensive enhancements to make the Elixir Stopwatch
a production-ready, professional-grade application with enterprise
features and developer tooling.
Major Additions:
1. Export Functionality (Stopwatch.Export)
- JSON export with full statistics and formatted times
- CSV export for laps and event history
- File I/O operations for data persistence
- CLI commands: export, save, load
2. Configuration System (Stopwatch.Config)
- Load/save configuration from .stopwatch.config.json
- Customizable default settings
- Support for format preferences and behavior options
3. Docker Support
- Multi-stage Dockerfile for minimal production images (~20MB)
- Docker Compose with dev and prod services
- Comprehensive Docker documentation
- .dockerignore for optimized builds
4. CI/CD Infrastructure
- GitHub Actions workflows for:
* Testing across multiple Elixir (1.14-1.16) and OTP (24-26) versions
* Code quality checks (format, Credo, Dialyzer)
* Automated escript builds
* Multi-platform releases (Linux, macOS)
* Hex.pm publishing automation
- Codecov integration for coverage tracking
5. Code Quality Tools
- Credo integration with comprehensive ruleset
- Dialyzer static analysis with PLT caching
- ExCoveralls for test coverage reporting
- Formatter configuration for consistent code style
6. Developer Experience
- Makefile with 15+ common development commands
- Benchmarking suite for performance testing
- Example scripts (basic_usage.exs, export_example.exs)
- Performance benchmarks for all major operations
7. GitHub Templates
- Bug report template (YAML format with validation)
- Feature request template (YAML format with priority)
- Pull request template with comprehensive checklist
8. Enhanced Documentation
- Complete API documentation (docs/API.md)
- Docker usage guide (docs/DOCKER.md)
- Updated README with all new features
- Inline examples and usage patterns
Dependencies Added:
- jason (~> 1.4) - JSON encoding/decoding
- credo (~> 1.7) - Code quality and linting
- dialyxir (~> 1.4) - Static analysis
- excoveralls (~> 0.18) - Coverage reporting
Files Changed:
- Modified: mix.exs, README.md, CHANGELOG.md, lib/stopwatch/cli.ex
- Added: 22 new files including Docker, CI/CD, docs, examples, and tools
This enhancement transforms the project from a simple stopwatch into
a professional, production-ready application with comprehensive
tooling, documentation, and deployment capabilities.
