During December 2025, Tom Peterka enhanced the spack/spack-packages repository by expanding its language support to include C alongside existing C++ (cxx) compatibility. He implemented this feature using Python, focusing on dependency and package management to ensure seamless integration of C code within the package resolution and build processes. This update addressed the need for broader platform portability and reduced integration friction for users deploying packages that require C. While no major bugs were reported or fixed during this period, Tom’s work emphasized code quality and maintainability, delivering a targeted improvement that increased reliability and ease of use for the repository.
