readline has been around for donkeys' years. I was hacking it in MKSToolkit back in the nineties. That implementation had a bug that hosed the debugger's command line and a shell work-around to resolve it. Presumably, there must be a clean-room version of readline somewhere that does not use GPL? bash owns the command line so applications should mimic its behavior, or at least offer a user-selectable option. Say, either emacs or vi editing modes, as bash itself does.

License questions need to be cleared with the LLVM Foundation.
But my non-lawyer understanding is no GPL.
