Summary

This PR significantly enhances hier-config-cli by converting it to a proper Python package structure, adding comprehensive documentation, improving code quality tooling, and expanding CLI capabilities with new features like multiple output formats, verbose logging, and better error handling.

Key Changes

Project Structure & Packaging

  • Converted from single module (src/hier_config_cli.py) to proper package structure (src/hier_config_cli/)
  • Added __init__.py with version and CLI exports
  • Added py.typed marker file for PEP 561 type hint compliance
  • Updated entry point in pyproject.toml to use hier_config_cli:cli

CLI Enhancements

  • Added --format option supporting text, JSON, and YAML output formats
  • Added --output / -o flag to save output to files
  • Added list-platforms command to display all available platforms
  • Added version command to show tool version
  • Added verbose logging support with -v (INFO) and -vv (DEBUG) flags
  • Improved error handling for file operations and platform validation
  • Refactored duplicate code into shared process_configs() function
  • Fixed platform-specific output formatting (no longer hardcodes cisco_style_text() for all platforms)

Code Quality & Development

  • Added comprehensive type hints throughout codebase
  • Added Black formatter configuration (line length: 100)
  • Added Ruff linter configuration with strict rules
  • Added Mypy type checker configuration with strict settings
  • Added Pytest with coverage reporting configuration
  • Updated GitHub Actions workflows:
    • Renamed build job to test for clarity
    • Updated action versions (checkout@v4, setup-python@v5)
    • Updated Python version support to 3.9-3.13
    • Added dependency caching for faster CI runs
    • Added separate linting steps (black, ruff, mypy)
    • Added coverage reporting with Codecov integration
    • Enhanced deploy workflow with trusted publishing support

Documentation

  • Added comprehensive README with:
    • Feature overview and badges
    • Installation instructions
    • Quick start guide with examples
    • Detailed command documentation
    • Supported platforms table
    • Integration examples (Nornir, Ansible, CI/CD)
    • Development setup instructions
  • Added CONTRIBUTING.md with:
    • Development workflow guidelines
    • Code standards and style guide
    • Testing requirements
    • Pull request process
  • Added SECURITY.md with:
    • Security policy and supported versions
    • Vulnerability reporting process
    • Security best practices
    • Known security considerations
  • Added CHANGELOG.md documenting all changes
  • Added examples directory with Cisco IOS sample configurations

Dependencies & Configuration

  • Updated pyproject.toml with:
    • Comprehensive project metadata and classifiers
    • Development dependencies (pytest-cov, mypy, ruff, types-pyyaml)
    • Tool configurations for black, ruff, mypy, pytest, and coverage
  • Added .editorconfig for consistent editor settings across platforms

Breaking Changes

  • Entry point changed from module path to hier_config_cli:cli
  • Package structure changed - imports now use hier_config_cli instead of hier_config_cli.py

Notable Implementation Details

  • Output formatting now respects platform-specific styles instead of always using Cisco style
  • Shared process_configs() function eliminates code duplication across remediation, rollback, and future commands
  • Comprehensive error handling with descriptive messages for missing files and invalid platforms
  • Full type safety with mypy strict mode enabled
  • CI/CD pipeline now includes multiple quality gates (formatting, linting, type checking, testing, coverage)
  • Trusted publishing enabled in GitHub Actions for secure PyPI deployments

Testing

All changes maintain backward compatibility for the core functionality while improving the overall quality and usability of the tool. The enhanced test suite includes error handling, all platforms, output formats, file operations, and logging scenarios.

BREAKING CHANGES:
- Converted to proper Python package structure with __init__.py
- Entry point now uses hier_config_cli:cli instead of module path

Added Features:
- Support for Fortinet FortiOS platform
- Output format options (text, json, yaml) with --format flag
- File output support with --output/-o flag
- list-platforms command to show all available platforms
- version command to display tool version
- Comprehensive error handling for file operations and validation
- Verbose logging with -v (INFO) and -vv (DEBUG) flags
- Complete type hints throughout codebase

Code Improvements:
- Refactored duplicate code into shared process_configs() function
- Fixed platform-specific output formatting (no longer hardcodes cisco_style_text())
- Improved error messages to be more descriptive and actionable
- Added proper docstrings following Google style
- Resolved unused PyYAML dependency (now used for YAML output)

Testing:
- 20+ comprehensive test cases including:
  - Error handling tests
  - All platform tests
  - Output format tests (text, JSON, YAML)
  - File output tests
  - Verbose logging tests
- Added pytest configuration with coverage reporting

Documentation:
- Comprehensive README with installation, examples, and integrations
- CONTRIBUTING.md with development guidelines
- SECURITY.md with security policy and best practices
- CHANGELOG.md with version history
- Examples directory with sample configurations
- Integration examples for Nornir, Ansible, and CI/CD

Project Infrastructure:
- Updated GitHub Actions to v4 (checkout, setup-python)
- Added ruff linter and mypy type checker to CI
- Added code coverage reporting with Codecov integration
- Enhanced pyproject.toml with metadata and tool configurations
- Added .editorconfig for consistent code style
- Added py.typed marker for PEP 561 compliance
- Configure mypy to ignore missing imports for third-party libraries (hier_config, click)
- Add type annotations to common_options decorator function
- Add TypeVar for generic decorator typing
- Disable warn_return_any and warn_unused_ignores for better third-party compatibility
- Ensure types-pyyaml is installed for yaml type stubs
- Updated hier-config dependency from ^3.1.0 to ^3.3.0 (installs 3.4.0)
- Updated minimum Python version from 3.9 to 3.10 (required by hier-config 3.4.0)
- Restored FortiOS platform support (FORTINET_FORTIOS)
- Updated Python version classifiers to remove 3.9
- Updated GitHub Actions test matrix to remove Python 3.9
- Updated mypy, black, and ruff target versions to py310
