When the eventloop of prompt-toolkit is idle, it can call such a hook. This hook can call another eventloop that runs for a short while, for instance to keep a graphical user interface responsive. It's the responsibility of this hook to exit when there is input ready. There are two ways to detect when input is ready: - Call the `input_is_ready` method periodically. Quit when this returns `True`. - Add the `fileno` as a watch to the external eventloop. Quit when file descriptor becomes readable. (But don't read from it.) Note that this is not the same as checking for `sys.stdin.fileno()`. The eventloop of prompt-toolkit allows thread-based executors, for example for asynchronous autocompletion. When the completion for instance is ready, we also want prompt-toolkit to gain control again in order to display that. An alternative to using input hooks, is to create a custom `EventLoop` class that controls everything. )unicode_literalsN) is_windows) select_fds)InputHookContextc6\rSrSrSrSrSrSrSrSr Sr g ) r$z( Given as a parameter to the inputhook. c[U5(deXlSUl[R"5uUlUlg)N)callable inputhook_input_is_readyospipe_r_w)selfr s 5lib/third_party/prompt_toolkit/eventloop/inputhook.py__init__InputHookContext.__init__(s4 """""#779c URSS9$)z& Return True when the input is ready.
