ev-manager (Event Manager)

Useful when working with DCCs like Maya, MotionBuilder, Unreal Engine, etc. and you want different tools/scripts to communicate with each other.

Installation:

pip install ev-manager

Examples:

Using classes:

""" my_module.py """

from typing import Callable
from ev_manager import Event

class ExampleEvent(Event[Callable[[int], None]]):
    pass

def my_callback(value: int):
    print(f"Number: {value}")

ExampleEvent.bind(my_callback)

>>> from my_module import ExampleEvent
>>> ExampleEvent.emit(5)
>>> "Number: 5"

Using functions:

import ev_manager

def hello_world():
    print("Hello World!")

ev_manager.bind("MyEvent", hello_world)

>>> import ev_manager
>>> ev_manager.emit("MyEvent")
>>> "Hello World!"

Available functions:

Function	Description
bind(event, function)	Bind a function to an event.
unbind(event, function)	Unbind a function from an event.
unbind_all(*, event, function)	Either unbind all functions from an event or unbind a function from all events.
is_bound(event, function)	Check if a function is bound to an event.
emit(event, *args, **kwargs)	Call all functions bound to an event.

Limitations:

Events are per Python instance. So they will for example not be communicating between different applications.
