PROFILE
Hajhouse
Over a two-month period, contributed to the PrairieLearn/PrairieLearn repository by enhancing both documentation and grading functionality. In April, focused on improving maintainability by correcting a docstring in the Feedback.check_scalar method, ensuring the documentation accurately reflected the logic for relative tolerance checks and reducing the risk of developer misinterpretation. In June, delivered a feature enabling regex-based correct answers in the pl-string-input component, allowing instructors to specify answer formats using regular expressions. This update, implemented with Python’s re.fullmatch and JavaScript, expanded assessment flexibility while maintaining backward compatibility. Additional work included documentation updates, lint fixes, and co-authored examples to support adoption.
