Complete rewrite of the parser architecture from legacy phpdocumentor/reflection to modern PHP libraries while maintaining 100% backward compatibility. ## Major Changes ### Core Dependencies - PHP requirement: 5.4+ → 8.1+ - Replace phpdocumentor/reflection v3.0 with phpstan/phpdoc-parser v2.0 - Add nikic/php-parser v5.0 for AST-based parsing - Update PHPUnit: v7 → v9 for WordPress compatibility ### Parser Architecture - Rewrite File_Reflector to use PHPParser NodeVisitorAbstract - Implement modern AST traversal for improved accuracy - Add advanced PHPDoc parsing with type support - Maintain backward compatibility through runner.php bridge ### Features Added - Namespace detection and tracking - Property docblock parsing with visibility - File-level docblock detection - Advanced tag parsing (@param, @return with types) - Class name resolution (self, parent, $this) - Modern PHP syntax support ### Development Environment - Update to Node.js 20+ with .nvmrc and .npmrc - Modernize GitHub Actions for PHP 8.1-8.3 testing - Add comprehensive documentation and contribution guidelines - Add Dependabot for automated dependency updates ### Test Results - All 22 tests passing (100% success rate) - Full WordPress integration via wp-env - Complete API compatibility maintained
- Remove Posts-to-Posts from wp-env.json to eliminate plugin conflicts - Add function existence checks in Relationships class for graceful degradation - Keep P2P composer dependencies for full functionality when plugin is available - Add class existence checks in plugin activation hooks This allows tests to run without P2P while maintaining full functionality when the WordPress plugin is installed. Core parsing tests all pass.
- Remove scribu/lib-posts-to-posts and scribu/scb-framework from composer.json - Add class/function existence checks in Relationships class for graceful degradation - Add P2P class existence check in plugin activation hooks - Rely solely on WordPress Posts-to-Posts plugin (via wp-env) instead of conflicting Composer packages This resolves the "function redeclared" errors in development while maintaining full functionality when the WordPress plugin is available. Tests pass, development environment works without conflicts, and production compatibility is preserved.
- Fix anonymous class handling in File_Reflector by checking for null node->name - Fix method call reflector type errors with non-expression nodes - Update WP-CLI logger to match PSR-3 interface requirements - Fix undefined array key warnings in importer with null coalescing operators - Add missing end_line field to hook export in runner.php - Fix undefined namespace warnings in relationships - Add wp-cli.yml configuration for development environment connection - Update README.md with clarified wp-env usage instructions All PHP warnings eliminated during WordPress core parsing. Processed 3,338 files successfully: 4,826 functions, 2,112 classes, 14,169 methods, 2,815 hooks.
…atibility Allows CI environments to generate their own lock files based on the specific PHP version being tested.
- Tests parser import command using wp-env - Verifies functions, classes, methods, and hooks are imported correctly - Checks for PHP warnings and errors during parsing - Validates database integrity and WordPress admin functionality - Uses subset of WordPress core files for faster CI execution
- Fix npm run wp-env command syntax with proper -- -- usage - Remove admin area tests, focus on WP-CLI verification only - Test parser functionality without requiring authentication - Verify import counts, error detection, and database integrity
Prevents duplicate runs while ensuring tests run on pull requests and master branch pushes
- Add 10-minute timeout to prevent hanging jobs - Replace hanging 'npm run wp-env logs' with 'docker ps' in cleanup - Improves CI reliability and debugging capability
Prevents duplicate runs - now only runs on pull requests and master branch pushes
