How can i call function with ahk hotkey?

[Eikosa]

from ahk import AHK, Hotkey
from ahk.directives import NoTrayIcon

ahk = AHK(directives=[NoTrayIcon])

def main(msg):
    print(msg)

hotkey = Hotkey(ahk, "up", main("a"))
hotkey.start()

Not worked.

Right now, there is no functionality to call Python functions as the result of a hotkey being triggered. Right now, only AHK scripts are supported as callbacks for hotkeys.

As described in the Readme:

from ahk import AHK, Hotkey

ahk = AHK()

key_combo = '#n' # Define an AutoHotkey key combonation
script = 'Run Notepad' # Define an ahk script
hotkey = Hotkey(ahk, key_combo, script) # Create Hotkey
hotkey.start()  #  Start listening for hotkey

Support for Python callbacks is planned for the future.

Python callbacks are now supported in v1!

from ahk import AHK

def my_callback():
    print('Hello callback!')

ahk = AHK()
# when WIN + n is pressed, fire `my_callback`
ahk.add_hotkey('#n', callback=my_callback)
ahk.start_hotkeys()  # start the hotkey process thread
ahk.block_forever()  # not strictly needed in all scripts -- stops the script from exiting; sleep forever

Hint: for adding arguments to the callback function, use lambda or functools.partial, or similar.

from functools import partial

def my_callback(msg):
    print(msg)
# ...
ahk.add_hotkey('#n', callback=partial(my_callback, "hello ahk"))
# OR
ahk.add_hotkey('#n', callback=lambda: my_callback("hello ahk"))
# OR
def wrapper():
    my_callback("hello ahk")
ahk.add_hotkey('#n', callback=wrapper)
