๐Ÿš€ Key Highlights

Critical Bug Fixes

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

Parser Improvements

  • ๐Ÿ”„ Parser.reset() method for parser instance reusability
  • ๐Ÿ› ๏ธ Helper methods - Extracted copy_path() to eliminate code duplication
  • ๐Ÿ“ Better documentation - Enhanced comments explaining Mojoโ€™s ownership model

Performance & Benchmarking

  • โšก Comprehensive benchmarks - New benchmark suite in benchmarks/benchmark_parser.mojo
  • ๐Ÿ“Š Performance documentation - docs/PERFORMANCE.md with detailed analysis
  • ๐Ÿ”ข Measured performance:
    • Simple parse: 26ฮผs (37,000 parses/sec)
    • Real pixi.toml: 2ms (446 parses/sec)
    • Table access: 10ฮผs overhead (negligible)

Testing Improvements

  • ๐Ÿ“ Reorganized tests - 10 logical test files (was 7)
  • ๐Ÿท๏ธ Better naming - test_basic.mojo โ†’ test_lexer.mojo
  • โœ… More tests - 96 tests total (up from 79)
  • ๐Ÿ“š Documentation - New docs/TEST_ORGANIZATION.md guide

Test Files: 1. test_lexer.mojo (25) - Lexer/tokenization 2. test_parser.mojo (10) - Parser core 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

  • ๐ŸŽจ Quickstart example - examples/quickstart.mojo mirrors README
  • ๐Ÿ“Š Enhanced parse_pixi.mojo - Comprehensive configuration reporting
  • ๐Ÿงช Test examples - examples/test_quickstart.mojo demonstrates testing

Project Organization

  • ๐Ÿ“‚ Organized docs - Moved documentation to docs/ directory
  • ๐Ÿšซ Proper .gitignore - Excludes build artifacts and binaries
  • ๐Ÿงน Clean repository - Removed accidentally committed binaries

๐Ÿ“ 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

๐Ÿ”„ Migration

No breaking changes! All enhancements are backward compatible.

๐Ÿ“ฆ Installation

# Git submodule (recommended)
git submodule add https://github.com/databooth/mojo-toml vendor/mojo-toml

# Direct copy
git clone https://github.com/databooth/mojo-toml
cp -r mojo-toml/src/toml your-project/lib/toml
