During February 2026, John Chen contributed to the EasyCrypt/easycrypt repository by addressing a critical formatting issue in the module path pretty-printer. He identified and resolved a bug that caused spurious line breaks between namespace components, which previously led to confusing outputs in generated code and logs. By refining the OCaml code responsible for string formatting, John removed unnecessary break hints in the printer logic, ensuring that qualified module paths display consistently and correctly. His work demonstrated strong debugging and functional programming skills, delivering a targeted, low-risk fix that improved code readability and stability without altering existing behavior elsewhere in the codebase.
