During January 2025, work focused on expanding language support in the Automattic/harper repository by implementing comment parsing for CMake build scripts. This involved integrating the tree-sitter-cmake parser and updating the existing CommentParser to recognize CMake language identifiers, enabling accurate extraction and processing of comments within CMake files. The approach leveraged Rust for both parsing logic and build system integration, laying the foundation for broader multi-language support and improved static analysis. By delivering this feature, the work enhanced documentation coverage and tooling consistency for CMake-based projects, aligning with ongoing efforts to strengthen parsing and build system capabilities in the codebase.
