Worked on updating the OpenBabel Homebrew formula within the Homebrew/homebrew-core repository to ensure compatibility with the latest master branch. The approach involved removing legacy patches related to math, CMake, and Eigen, which were no longer necessary due to upstream changes. By streamlining the installation process and eliminating redundant fixes, the update reduced the risk of future breakage and simplified ongoing maintenance. The work leveraged Ruby for formula scripting, CMake for build configuration, and package management best practices to align closely with upstream OpenBabel development, resulting in a more maintainable and robust formula for future Homebrew updates.
