Automate packing with Themida

Here is the script that was used to generate the Themida samples using GUI automation:

import os
import pyautogui as pag
import pyperclip
import time

pag.PAUSE = .2

HOME = os.path.join(os.path.expanduser("~"), "Desktop")

# setting: stick Themida's window to the left half of the screen
def pack(filename):
    # does not use ":" as it does not translate to the right character (keyboard layout issue)
    fin = os.path.join(HOME, "not-packed", filename)
    fout = os.path.join(HOME, "Themida", "themida_" + filename)
    # click on "Input Filename" field and fill in the input file
    pag.click(400, 280)
    pag.hotkey("ctrl", "a")
    pag.press("backspace")
    type_path(fin)
    # click on "Output Filename" field and fill in the output file
    pag.click(400, 310)
    pag.hotkey("ctrl", "a")
    pag.press("backspace")
    type_path(fout)
    # click on the "Protect" button then "OK"
    pag.click(250, 150)
    pag.click(980, 500)
    # wait for the button to become "Close" and then click on it
    button = None
    while not button:
        time.sleep(.5)
        button = pag.locateCenterOnScreen(os.path.join(HOME, "close-button.png"), grayscale=True)
    pag.click(700, 670)
    # now free the input fields
    pag.click(400, 280)
    pag.hotkey("ctrl", "a")
    pag.press("backspace")
    pag.click(400, 310)
    pag.hotkey("ctrl", "a")
    pag.press("backspace")

def type_path(path):
    if path.startswith("C:"):
        path = path[2:]
        pag.typewrite("C", interval=.01)
        pyperclip.copy(":")
        pag.hotkey("ctrl", "v", interval=.01)
    pag.typewrite(path, interval=.01)

for f in os.listdir("not-packed"):
    pack(f)
