Mar 1, 2025March 2025 monthly summary for y-scope/clp. The team delivered a focused modernization of the build and CI stack, resolved critical header and lint issues, and standardized error handling across core modules, resulting in improved cross-platform reliability, higher code quality, and clearer maintenance paths. Key outcomes: - Build system modernization and macOS toolchain updates: updated CMake to require C++20-capable compilers, added LLVM Clang 16 toolchain support on macOS, integrated ystdlib-cpp as a submodule, and refreshed developer guide dependencies to mirror latest versions. - Stability and quality improvements: fixed clang-tidy violations and compilation errors in GlobalMetadataDBConfig.hpp, including refactoring default constructors and adding a default port constant; lint-tasks.yml updated to exclude resolved files. - Consistent error handling across modules: migrated clp to ystdlib::error_handling and adjusted regex_utils to use ystdlib::error_handling::ErrorCode, with corresponding build/config updates. Impact: reduces CI failures and build frictions, improves cross-platform reliability (macOS), accelerates onboarding with updated docs, and strengthens error handling guarantees across the lightweight stack. Technologies/skills demonstrated: CMake, macOS toolchains (Clang 16), submodule management, clang-tidy, linting orchestration, and error-handling architecture across C++ modules.
