Main loaders

------------

Loader

------

With Loader you could register sorted python modules. When you ask for a class

it will try to load it for each module until it find one.

**Example**:

.. code-block:: python

    from dirty_loader import Loader

    loader = Loader()

    loader.register_module('tests.fake.namespace1')

    loader.register_module('tests.fake.namespace2')

    loader.register_module('tests.fake.namespace3')

    klass = loader.load_class('FakeClass1')

    from tests.fake.namespace1 import FakeClass1

    assert klass == FakeClass1

    # klass is tests.fake.namespace1.FakeClass1 because it exists in first module registered.

    # Also, you could get an instance of class using factory

    obj = loader.factory('FakeClass1', var1='a', var2=2)

    # You could load classes from packages inside modules registered

    klass = loader.load_class('subnamespace.FakeClass1')

    from tests.fake.namespace3.subnamespace import FakeClass1 as SubFakeClass1

    assert klass == SubFakeClass1

    # klass is tests.fake.namespace3.subnamespace.FakeClass1 because it exists in first module registered.

LoaderReversed

--------------

It works in same way of Loader but it revers the sort when try to load a class.

**Example**:

.. code-block:: python

    from dirty_loader import LoaderReversed

    loader = LoaderReversed()

    loader.register_module('tests.fake.namespace1')

    loader.register_module('tests.fake.namespace2')

    klass = loader.load_class('FakeClass1')

    from tests.fake.namespace2 import FakeClass1

    assert klass == FakeClass1

    # klass is tests.fake.namespace2.FakeClass1 because it exists in last module registered.

LoaderNamespace

---------------

With LoaderNamespace you could register sorted namespaces. When you ask for a class

it will try to load it for each namespace until it find one. Each namespace has a python

module associated. You could use the regular Loader way to load a class or you could

specify the namespace you would like to use.

**Example**:

.. code-block:: python

    from dirty_loader import LoaderNamespace

    loader = LoaderNamespace()

    loader.register_namespace('fake1', 'tests.fake.namespace1')

    loader.register_namespace('fake2', 'tests.fake.namespace2')

    from tests.fake.namespace1 import FakeClass1, FakeClass2, FakeClass3

    klass = loader.load_class('FakeClass1')

    from tests.fake.namespace1 import FakeClass1

    assert klass == FakeClass1

    # klass is tests.fake.namespace1.FakeClass1 because it exists in last module registered.

    # Also, you could get a class from specific namespace

    klass = loader.load_class('FakeClass1', namespace='fake2)

    from tests.fake.namespace2 import FakeClass1

    assert klass == FakeClass1

    # klass is tests.fake.namespace2.FakeClass1 because you specified it.

    # Namespace could be specified in string class, too

    klass = loader.load_class('fake2:FakeClass1')

    assert klass == FakeClass1

    # klass is tests.fake.namespace2.FakeClass1 because you specified it.
