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. iÿÿÿÿ(tunicode_literalsN(t is_windowsi(t select_fdsuInputHookContexttInputHookContextcBs;eZdZd„Zd„Zd„Zd„Zd„ZRS(u0 Given as a parameter to the inputhook. cCs@t|ƒst‚||_d|_tjƒ\|_|_dS(N( tcallabletAssertionErrort inputhooktNonet_input_is_readytostpipet_rt_w(tselfR((sAlib/python2.7/site-packages/prompt_toolkit/eventloop/inputhook.pyt__init__(s  cCs|jdtƒS(u6 Return True when the input is ready. twait(RtFalse(R ((sAlib/python2.7/site-packages/prompt_toolkit/eventloop/inputhook.pytinput_is_ready0scCs|jS(u\ File descriptor that will become ready when the event loop needs to go on.
