initify 0.1.4

Simplify your __init__(self) function.

The missing magical python decorator for simplifying your __init__(self, ...) function.

@init_args # Magical decorator
def __init__(self, name="Lovely Lucy", age=10):
    pass

p = Person()
p.name # "Lovely Lucy"
p.age  # 10 **Sweet**!

Inherited variables from super class

If you have polymorphism structured classes, you’d love initify.

class Animal:
    def __init__(self, obj):  # REQUIRED reserve "obj" for super class injecting
        self.age = 0
        self.name = ""
        self.color = ""
        ...

class Dog(Animal):
    @init_args
    def __init__(self, pet=True):
        pass
    ...

class Cat(Animal):
    @init_args
    def __init__(self, wild=False):
        pass
    ...

d = Dog(age=3, name="Golfy", color="black")
d.age    # 3
d.name   # Golfy
d.color  # black
d.pet    # True

c = Cat()
c.age   # 0
c.name  # ""
c.color # ""
c.wild  # False

---

That’s dull :/ Don’t judge until you see this:

Exclused variables

# Must declare with new-style class in python 2.7 or earlier
# ``class Animal:`` is fine if using python 3 or later
class Animal(object):
    def __init__(self):
        self.age = 0
        self.name = ""
        self.color = ""
        ...
        self.barks = True  # Only dog barks
        self.meows = True  # and only cat meows
        ...

class Dog(Animal):
    @init_args(exclude=['meows'])  # Don't inherit meows from super class!
    def __init__(self, pet=True):
        pass
    ...

class Cat(Animal):
    @init_args(exclude=['barks'])  # Don't inherit barks from super class!
    def __init__(self, wild=False):
        pass
    ...

d = Dog(age=3, name="Golfy", color="black")
d.age    # 3
d.name   # Golfy
d.color  # black
d.pet    # True
...
d.barks  # True
d.meows  # Attribute Error: meows is not defined!

c = Cat()
c.age   # 0
c.name  # ""
c.color # ""
c.wild  # False
...
d.meows  # True
d.barks  # Attribute Error: barks is not defined!

Now this is neat hey?

Installation

Install initify with pip or pip3.

pip install initify

pip3 install initify

Then whichever class you’re using initify, do an import before using. Example:

from initify import init_args

Now you can attach the decorator @init_args right before the class’s initializer def ___init___(self, ...). Enjoy your effort.

Support

Hope this decorator can help you with your `DRY-iness in your python project!

If you have any suggestion, please don’t hesistate to give a post on the issue page.

Cheers and happy hacking!
