April 2026 — Glaze YAML serialization: delivered reliability improvements and metadata-driven control. Key features delivered: 1) YAML Serialization Enhancements: Custom Types and Metadata-driven Field Skipping, enabling proper inline representations for custom types and honoring skip/skip_if metadata during write. 2) YAML Handling: Quoting for Comma-containing Strings, ensuring strings with commas are properly quoted to prevent ambiguous or invalid YAML outputs. Major bugs fixed: comma-containing strings are now correctly quoted in needs_quoting(), and the YAML writer respects skip/skip_if flags and custom types across both inline and block representations. Added unit tests to validate edge cases and guard against regressions. Overall impact: more robust, correct, and maintainable YAML outputs, reducing downstream data integrity issues and manual debugging. Technologies/skills demonstrated: YAML schema and writer customization in C++, template-based serialization, metadata-driven controls, custom type handling, and expanded unit test coverage.
