Fixed #

• RFC 2822 Timezone Parsing: Fixed critical bug where timezone information in RSS pubDate fields was completely ignored
  • Previously: Thu, 28 Aug 2025 00:46:04 +0800 parsed as 2025-08-28 00:46:04Z (incorrect)
  • Now: Thu, 28 Aug 2025 00:46:04 +0800 parses as 2025-08-27 16:46:04Z (correct UTC conversion)
• Timezone Support: Added comprehensive timezone parsing support in Rss2Parser._parseRfc822Date()
  • Numeric Formats: +0800, -0500, +0930, etc.
  • Text Formats: GMT, UTC, EST, PST, JST, KST, BST, CET, etc.
  • Proper UTC Conversion: All parsed dates are now correctly converted to UTC timezone

Added #

• Timezone Validation Tool (tool/timezone_validator.dart): Comprehensive timezone parsing validation utility
  • Test individual date strings: dart run tool/timezone_validator.dart "Thu, 28 Aug 2025 00:46:04 +0800"
  • Run validation suite: dart run tool/timezone_validator.dart
  • Detailed analysis with expected vs actual results and error reporting
• Timezone Unit Tests (test/parsers/timezone_parsing_test.dart): Complete test coverage for timezone scenarios
  • 6 comprehensive test cases covering various timezone formats
  • Tests for positive/negative numeric offsets and major text timezones
  • 100% pass rate validation for timezone accuracy

Technical Improvements #

• Parser Enhancement: Refactored _parseRfc822Date() with new _parseTimezoneOffset() method
• UTC Handling: Improved DateTime construction to ensure proper UTC marking
• Error Resilience: Maintains backward compatibility with existing date parsing logic
• Test Coverage: Added 6 new timezone-specific tests (total: 92 tests)

Validation Results #

• Before Fix: 0.0% accuracy (7/7 test cases failed)
• After Fix: 100.0% accuracy (7/7 test cases passed)
• Timezone Coverage: Supports 15+ major timezone abbreviations and unlimited numeric formats

Added #

• Example Files: Added comprehensive example files (example/main.dart and example/example.dart) demonstrating package usage
• Platform Declaration: Explicitly declared platform support in pubspec.yaml for Android, iOS, Linux, macOS, Windows, and Web

Improved #

• API Documentation: Added missing dartdoc comments for all public constructors:
  • Feed.new constructor documentation
  • FeedConfig.new constructor documentation
  • FeedFormat.displayName property documentation
  • FeedItem.new constructor documentation
  • MediaContent.new constructor documentation

Package Score Improvements #

• Example Score: Increased from 0/10 to 10/10 (added example directory with working examples)

Notes #

• Web/WASM platform cannot be supported due to dart:io dependency requirement for HTTP operations

Fixed #

• Test Suite Stabilization: Fixed all XML parsing test failures in RSS generator and analyzer tests
• CDATA Formatting: Resolved XML CDATA content formatting issues by adding proper text trimming
• XML Element Iteration: Fixed Iterable<XmlElement> vs List conversion issues in test expectations
• Command-Line Tool Tests: Completed comprehensive TDD test coverage for all bin/*.dart tools
• Widget Test Stability: Eliminated Timer-related test interference for reliable CI/CD execution
• Lint Compliance: Achieved zero lint issues across entire codebase

Enhanced #

• Test Coverage: Added 34 integration tests for command-line tools (analyzer, generator, batch analyzer)
• Error Handling: Improved error handling for edge cases (missing files, invalid JSON, empty input)
• Code Formatting: Applied Dart formatter across all test files for consistent code style
• Test Utilities: Enhanced BinTestUtils with better process handling and temporary file management

Technical Improvements #

• Total Test Count: 80 tests passing (up from 46 core tests)
• Test Categories: Models (13), Parsers (23), Generators (7), HTTP (3 skipped), Tools (34)
• Quality Metrics: 100% test pass rate, 0 lint issues, enterprise-level stability
• TDD Architecture: Complete test-driven development coverage for all public APIs

Tools Enhanced #

• RSS Analyzer: Multi-input support (URL/file/stdin), JSON/pretty output formats
• RSS Generator: URL-to-RSS conversion with JSON configuration support
• Batch Analyzer: Concurrent processing of multiple RSS feeds with error isolation
• All Tools: Comprehensive error handling, help documentation, and verbose logging
