replServer.displayPrompt([preserveCursor])


replServer.displayPrompt() 方法会让 REPL 实例做好用户输入的准备,打印配置的 promptoutput 中新的一行,然后返回 input 等待新的输入。

当正在键入多行输入时,会打印省略号而不是提示符。

preserveCursortrue 时,游标位置不会被复位到 0

replServer.displayPrompt 方法主要被使用 replServer.defineCommand() 方法注册的命令的 action 函数调用。

The replServer.displayPrompt() method readies the REPL instance for input from the user, printing the configured prompt to a new line in the output and resuming the input to accept new input.

When multi-line input is being entered, an ellipsis is printed rather than the 'prompt'.

When preserveCursor is true, the cursor placement will not be reset to 0.

The replServer.displayPrompt method is primarily intended to be called from within the action function for commands registered using the replServer.defineCommand() method.
