Worked on the NotAShelf/nvf repository, focusing on the assembly language plugin to enhance reliability and maintainability. Addressed a bug by reverting a previous expansion of filetype support, restoring the plugin to handle only 'asm' and 'vmasm' files. This targeted rollback, managed through Git, simplified the plugin’s scope and reduced the risk of misbehavior across different environments. The work involved Nix for configuration and plugin development, emphasizing language support and careful change management. No new user-facing features were introduced during this period, with efforts concentrated on stabilizing existing functionality and ensuring compatibility for ongoing maintenance.
