During February 2025, Johnstonskj developed experimental support for the Simple Domain Modeling Language (SDML) within the Topiary formatter repository. Focusing on code formatting and language parsing, he integrated SDML into the CLI’s contributed languages, enabling broader extensibility for users. His technical approach emphasized maintainability, with targeted code cleanup and configuration management updates to streamline future experiments and contributor onboarding. Using Rust and TOML, he expanded the SDML formatter’s test coverage to over 90 percent, aiming for comprehensive validation. The work prioritized feature delivery and robust testing, laying a foundation for quicker iteration and improved code quality across the project.
February 2025 monthly summary: Implemented experimental SDML support in the Topiary formatter, integrated SDML into the CLI contributed languages, and advanced test coverage and maintainability through targeted cleanup and configuration updates. No major bugs fixed this month; primary focus was feature delivery, testing, and code quality to enable quicker iteration and broader extensibility across the tweag/topiary repository.
