Simon Johnston

Developed experimental support for the Simple Domain Modeling Language (SDML) within the tweag/topiary repository, focusing on integrating SDML into the Topiary formatter and expanding its presence in the CLI’s contributed languages. Emphasized code formatting, language parsing, and configuration management using Rust and TOML, while prioritizing maintainability and extensibility for future development. Advanced the SDML formatter’s test coverage to over 90 percent, updating the test suite to ensure robust validation of new language paths. The work included targeted code cleanup and configuration updates, streamlining contributor onboarding and enabling quicker iteration cycles without addressing major bugs during this feature-focused development period.
