PROFILE
Hui Peng
Contributed to the google/xls repository by expanding and refining its C API, focusing on interoperability, runtime type introspection, and robust bit-level data handling. Delivered features such as value and type inspection, BitsRope manipulation, and APIs for converting and constructing bit representations, all implemented in C and C++. Enhanced memory management and safety by introducing dedicated APIs and addressing lifetime issues in data structures. Developed comprehensive tests and tooling, including Python scripts for symbol hygiene, to ensure reliability and maintainability. The work emphasized low-level programming, system programming, and software testing, resulting in a more accessible and reliable XLS library interface.

Apr 1, 2025April 2025: Delivered new C API capabilities for google/xls to improve interoperability and data handling, focusing on value-kind inspection and bit conversion utilities. Implemented through two commits adding a C API to inspect value kinds (xls_value_get_kind) and a set of bit-conversion APIs (xls_bits_to_bytes, xls_bits_to_uint64, xls_bits_to_int64). These changes simplify cross-language data exchange, reduce downstream boilerplate, and enhance the XLS library's data interoperability.
