yaphs

Yet another python hook system for python 2.7/3.x

Usage

Basic usage

Import yaphs

from yaphs import Hook

Register foo as a hook-compatible function

@Hook
def foo(*args):
    print(args)

Register bar as a hook to be executed before calling foo

@foo.before(*args):
def bar(*args):
    print('before foo, args: ' + str(args))

When you call foo, bar is called before

foo(1, 2)

Expected output:

before foo, args: (1, 2)
(1, 2)

Class usage (python 3.x only)

You can use yaphs hooks inside classes:

class MyClass:
    @Hook
    def foo(self, *args)

When you register hooks, you just have to know that the first argument will be the object

c = MyClass()

@c.foo.after:
def bar(o, *args):
    print('after foo')
    print('object: ' + str(o))
    print('args: ' + str(args))
