🎉 Quality and Performance Release

mojo-toml v0.3.0 brings critical bug fixes, comprehensive testing improvements, performance documentation, and enhanced examples. All 96 tests passing!

---

🚀 Key Highlights

Critical Bug Fixes

• ✅ Proper dotted key support - a.b.c = "value" now creates nested structures correctly
• ✅ Duplicate key detection - Raises errors when duplicate keys are found
• ✅ Enhanced error messages - All errors now include line and column context
• ✅ Named type constants - Replaced magic numbers with TomlValueType struct using comptime

Parser Improvements

• 🔄 Parser.reset() method for parser instance reusability
• 🛠️ Helper methods - Extracted copy_path() to eliminate code duplication
• 📝 Better documentation - Enhanced comments explaining Mojo's ownership model

Performance & Benchmarking

• ⚡ Comprehensive benchmarks - New benchmark suite in benchmarks/benchmark_parser.mojo
• 📊 Performance documentation - docs/PERFORMANCE.md with detailed analysis
• 🔢 Measured performance:
  • Simple parse: 26μs (37,000 parses/sec)
  • Real pixi.toml: 2ms (446 parses/sec)
  • Table access: 10μs overhead (negligible)

Testing Improvements

• 📁 Reorganized tests - 10 logical test files (was 7)
• 🏷️ Better naming - test_basic.mojo → test_lexer.mojo
• ✅ More tests - 96 tests total (up from 79)
• 📚 Documentation - New docs/TEST_ORGANIZATION.md guide

3. test_real_world.mojo (4) - Real files
4. test_fixtures.mojo (5) - Complex examples
5. test_arrays.mojo (14) - Array parsing
6. test_inline.mojo (13) - Inline tables
7. test_tables.mojo (8) - Table headers
8. test_dotted_keys.mojo (7) - Dotted keys [NEW]
9. test_validation.mojo (7) - Error detection [NEW]
10. test_parser_reset.mojo (3) - Parser API [NEW]

Enhanced Examples

• 🎨 Quickstart example - examples/quickstart.mojo mirrors README
• 📊 Enhanced parse_pixi.mojo - Comprehensive configuration reporting
• 🧪 Test examples - examples/test_quickstart.mojo demonstrates testing

📝 Technical Details

Dotted Key Implementation

# Now properly creates nested structure:
a.b.c = "value"  
# Results in: {a: {b: {c: "value"}}}

Duplicate Key Detection

key = "value1"
key = "value2"  # Error: "Duplicate key: key"

Error Context

Error: Unexpected token at line 5, column 12

🔄 Migration

No breaking changes! All enhancements are backward compatible.
