# Module Initialize
## Introduction
A module is usually a mixin, so when an `#initialize` method is present it is
hard to tell initialization order and parameters so having `#initialize`
in a module is usually a bad idea.
## Example
The `Foo` module below contains a method `initialize`. Although class `B` inherits from `A`, the inclusion of `Foo` stops `A#initialize` from being called.
```Ruby
class A
def initialize(a)
@a = a
end
end
module Foo
def initialize(foo)
@foo = foo
end
end
class B < A
include Foo
def initialize(b)
super('bar')
@b = b
end
end
```
A simple solution is to rename `Foo#initialize` and call that method by name:
```Ruby
module Foo
def setup_foo_module(foo)
@foo = foo
end
end
class B < A
include Foo
def initialize(b)
super 'bar'
setup_foo_module('foo')
@b = b
end
end
```
## Current Support in Reek
Reek warns about module initialize when an instance method named `initialize` is present in a module.
## Configuration
Module Initialize supports the [Basic Smell Options](Basic-Smell-Options.md).
