Summary of Changes

Hello @waruqi, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request streamlines the process of retrieving default CMake build flags within the xmake package module. It simplifies the internal logic by consolidating flag handling and removing unnecessary conditional checks, leading to cleaner and more maintainable code for CMake integration.

Highlights

  • Simplified CMake Flag Retrieval: The _get_envs_for_default_flags function has been refactored to directly return a cloned set of default CMake flags, removing verbose conditional checks for various flag types (e.g., CXX, C, linker flags). This streamlines the logic and reduces code complexity.
  • Redundant Null Check Removal: A redundant or {} null check was removed from the call to _get_envs_for_default_flags in _get_envs_for_flags, as the refactored _get_envs_for_default_flags function now guarantees a table return.

Code Review

This pull request refactors the logic for handling default CMake flags. The _get_envs_for_default_flags function is greatly simplified to clone all default flags returned by CMake, rather than selectively copying them. This changes the behavior to always include CMake's default flags and append any user-provided flags, which is a more intuitive and robust approach. Previously, providing any custom flag would cause all default flags of that type to be omitted. The change also includes a minor cleanup by removing a now-redundant nil-check. The changes are well-implemented, improve code clarity, and fix the underlying logic for flag handling.
