Extensions

Concert allows third-party extensions to reside under a common namespace concert.third.* similar to the Flask extension system. To achieve this, extensions must be modules or packages named concert_name and be installed with setuptools like this:

from setuptools import setup

setup(
    name='Concert-Foo',
    version='1.0',
    url='...',
    author='...',
    py_modules=['concert_foo'],
    zip_safe=False,
    install_requires=[
        'concert',
    ]
)

After successful installation, the user can import a third-party extension simply like this:

from concert.third.foo import SomeClass, some_func
