Marco Lanari developed and maintained core features for the smeup/jariko repository, focusing on RPG interpreter and compiler enhancements, build system modernization, and robust test infrastructure. He applied Java and Kotlin to optimize data structure handling, improve performance profiling, and ensure reliable serialization and error handling. Marco introduced map-based lookups for faster compile-time resolution, refactored build automation to support Sonatype Central Portal publishing, and expanded test coverage for interpreter state synchronization. His work included detailed technical documentation and migration guides, supporting onboarding and ongoing development. Through systematic refactoring and targeted bug fixes, he improved maintainability, runtime stability, and development velocity.

Jul 1, 2025July 2025 monthly summary for smeup/jariko focused on stabilizing interpreter-state synchronization across components by delivering a dedicated test suite that validates shared state between the interpreter and its associated function statuses. This work reduces state drift and increases confidence in runtime behavior across indicators, key lists, last DB file, inzsrExecuted, and lastFound.

May 1, 2025May 2025 performance and stability focus for smeup/jariko. Key outcomes include speedups in compile-time data resolution via map-based lookups and tryToResolve, structural data-access improvements with new by-name maps, a clarified feature flag (createSymbolTable not implemented) to reduce risk, targeted refactors of DS builders and input handling for future Kotlin compatibility, and a stability-focused BOMInputStream overhaul with a controlled revert to ensure reliable I/O behavior. These changes improve build speed, API clarity, and overall maintainability, delivering tangible business value in faster iterations and more predictable behavior.
