If you type } after {, ) after ( or ] after [ in CLISP (and I'm sure many more) terminal, the corresponding opening bracket gets highlighted for about a second, before returning to normal state.
如果在[,CLISP之后(或我确定更多)终端之后(或)之后键入},则在返回正常状态之前,相应的左括号会突出显示大约一秒钟。
How can I get this behavior, at least when doing gets in Ruby, cin in C++ and scanf in C?
我怎么能得到这种行为,至少在使用Ruby时,cin用C ++和scanf用C?

To control things like cursor position, text formatting and so on, you have to talk directly to the terminal, in a way which is not accessible through the stream interfaces of cin of scanf. Not sure about Ruby, but I'd guess the same applies there as well. On POSIX systems, this control is achieved via a set of I/O controls (ioctl), which provide an out-of-band communication with the terminal device. There are libraries which provide some degree of portability when talking to a terminal. The most commonly used is probably ncurses, which was already mentioned by David Rodríguez.
要控制光标位置,文本格式等内容,必须直接与终端通信,这种方式无法通过scanf的cin流接口访问。不确定Ruby,但我猜这同样适用。在POSIX系统上,该控制是通过一组I / O控制(ioctl)实现的,它们提供与终端设备的带外通信。有些库在与终端通信时提供一定程度的便携性。最常用的可能是ncurses,DavidRodríguez已经提到了这一点。
