Simon Johnston

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.
