        "description": "Middleware for Python\n=====================\n\n**Copyright (c) 2016 David Betz**\n\nInstallation\n------------\n\n::\n\n    pip install middleware\n\n|Build Status| |PyPI version|\n\nCompatibility\n-------------\n\nPython 2 and 3\n\nPurpose\n-------\n\nMost everyone needs a concept of middleware.\n\nFollowing are examples of using this, see ``test_middleware.py`` for\nfull examples.\n\n::\n\n    class AdditionMiddleware1(Middleware):\n        def create(self):\n            def func(mwa, context):\n                try:\n                    counter = context['counter']\n                except:\n                    counter = 0\n                context['counter'] = counter + 1\n\n                return next(mwa)\n\n            return func\n\nWhen using a class, add a ``create`` function which returns a function.\nThis inner fuction accepts the middleware array and the data context and\nreturns ``next(mwa)`` to create a middleware chain.\n\nFor this example, I'll add two more:\n\n::\n\n    class AdditionMiddleware2(AdditionMiddleware1):\n        pass\n\n\n    class AdditionMiddleware3(AdditionMiddleware2):\n        pass\n\nNow to run it. Use ``set`` to set an array of middleware and ``add`` to\nadd one to the array. ``set`` overwrites everything. That's just what\n``set`` means.\n\n::\n\n        handler = Handler()\n        handler.set([AdditionMiddleware1, AdditionMiddleware2])\n        handler.add(AdditionMiddleware3)\n        handler.execute()\n\n        # handler['counter'] == 3\n\nIn this case, there is no initial context and each of the three\nmiddleware increment a counter ending with ``handler['counter'] == 3``.\n\nYou can skip the entire class stuff too:\n\n::\n\n    handler = Handler()\n    def inline(wma, context):\n        context['myvalue'] = 12\n    handler.add(inline)\n    handler.execute()\n    # handler['myvalue'] == 12\n\nUse the following to send initial context:\n\n::\n\n    handler = Handler(counter=1)\n\nIt's actually ``kwargs``, so you can load it up:\n\n::\n\n    handler = Handler(**{'a': 1, 'b': 2})\n    def inline(wma, context):\n        context['a'] = context['a'] + context['b']\n    handler.add(inline)\n    handler.execute()\n\n.. |Build Status| image:: https://travis-ci.org/davidbetz/pymiddleware.svg?branch=master\n   :target: https://travis-ci.org/davidbetz/pymiddleware\n.. |PyPI version| image:: https://badge.fury.io/py/middleware.svg\n   :target: https://badge.fury.io/py/middleware",
