Worked on enhancing the command-line interface workflow for the shengxinjing/ollama repository by implementing command history navigation improvements. Focused on Go programming and CLI development, the work introduced support for Ctrl+N and Ctrl+P shortcuts, enabling users to navigate command history more efficiently. The history logic was refactored into dedicated historyPrev and historyNext functions, and additional handling for CharPrev and CharNext was added to support the new shortcuts. These changes aligned the CLI with common terminal behaviors, improving usability and productivity for developers. The update addressed a core aspect of user interaction, emphasizing maintainable and modular code structure throughout.
