Worked on the mpv-player/mpv repository to address a runtime error in console input handling by refining the Lua scripting logic within console.lua. The solution involved defaulting the input.select prompt to an empty string when no prompt is provided, which prevented nil concatenation errors and improved compatibility with older versions of mpv. This targeted bug fix enhanced the robustness of input handling while minimizing risk to existing functionality. The work demonstrated careful change management and scripting skills, resulting in a maintainable patch with a clear audit trail. The focus remained on stability, backward compatibility, and precise bug resolution using Lua.
