Arnold Lankamp
Worked on enhancing the usethesource/rascal repository by improving parser robustness and debugging capabilities. Addressed a bug in the parser’s internal logic to prevent incorrect reuse of separators during parse forest flattening, which increased the reliability of parsing results. Persisted raw Java source in debug mode to facilitate more effective troubleshooting and diagnosis. Expanded test coverage by introducing a targeted test for the parser’s handling of expandable shared triple nullable separators. Utilized skills in Java, Abstract Syntax Trees, and parser development to deliver more stable and maintainable code, supporting downstream tools with improved parsing accuracy and easier debugging workflows.
