inputer: Print before input

If you want to print something before Python default function input() prompt, you can use this package inputer. To achieve this, inputer give you a object to control input like this:

import inputer
import threading
import time

input_handle = inputer.Inputer()

def always_print(input_handle):
    while True:
        input_handle.print_before("I am here!")
        time.sleep(1)

th = threading.Thread(target=always_print, args=(input_handle,), daemon=True)
th.start()

while True:
	text = input_handle.input("> ")
	if text == "exit":
		break

In addition, you can use following methods of Inputer to control input:

• Inputer.input(prompt=''): Just like Python default function input;
• Inputer.print_before(*args, **kwargs): Just like Python default function print but print before input prompt;
• Inputer.eprint_before(*args, **kwargs): Print before input prompt to stdandar error;
• Inputer.left(n=1): Move current cursor back n position, just like press left key on keybord;
• Inputer.right(n=1): Move current cursor forward n position, just like press right key on keybord;
• Inputer.up(n=1): Change current input buffer to last input text, just like press up key on keybord;
• Inputer.down(n=1): Change current input buffer to next input text, just like press down key on keybord;
• Inputer.backspace(n=1): Left delete n characters, just like press backspace key on keybord;
• Inputer.delete(n=1): Right delete n characters, just like press del key on keybord;
• Inputer.current_str: Get current input buffer text;
• Inputer.current_cursor: Get current cursor position;
• Inputer.insert(text): Insert text at current cursor position;
• Inputer.hide(): Hide prompt text and user input text;
• Inputer.unhide(): Show prompt text and user input text again;
• Inputer.block(): Forbidden user input;
• Inputer.unblock(): Allow user input again;
• Inputer.use_history(history_filename): All history input is saved in a history file even if you don't call this method. This method allow you to specify a history file to save history input in;
