Worked on targeted improvements across helix-editor/helix and ScoopInstaller/Main, focusing on reliability and user experience. Addressed a parsing issue in grammars.nix by refining the GitHub URL regex, which eliminated an ill-defined escape warning and reduced runtime noise. In ScoopInstaller/Main, implemented a feature to persist user configuration and cache data for Sing-box, ensuring data integrity across sessions and streamlining user workflows. Leveraged Nix scripting, configuration management, and PowerShell to deliver these enhancements. The work demonstrated careful attention to cross-repository collaboration, robust regex handling, and practical solutions for data persistence, contributing to more stable and user-friendly development environments.
