Worked on the aquasecurity/trivy repository to refactor home directory expansion by replacing the deprecated go-homedir package with Go’s standard library os.UserHomeDir function. Developed an expandHome helper to centralize and standardize path expansion logic, ensuring consistent handling of user home directories across platforms. Added comprehensive unit tests to verify correctness and edge case coverage, improving reliability and maintainability. This update reduced external dependencies, aligning the codebase with Go best practices and decreasing long-term maintenance risk. The work focused on dependency management, Go programming, and unit testing, resulting in a more robust and portable solution for home directory path handling.
