- Allow users to provide autocomplete callback of the form `std::vector<std::string> autocomplete(const std::string &input)` - When Tab is pressed on the keyboard, and a callback has been supplied to the `CliPrompt` instance, call it - If only one string is in the returned vector, replace the current input with that string - If more than one, do what (ba)sh does: - Print newline - List all autocomplete options while respecting console width (which will always be 32 afaik) - Reprint prompt with input
