wsgistraw 0.1

Decorators for WSGI without start_response and write

wsgistraw is a tiny Python library that simplifies coding WSGI applications and middleware by removing start_response and write from signatures of functions. This leads to a signature like:

def app(environ):
    return "200 OK", [("Content-Type", "text/plain")], ["Hello World!"]

That is, return a three-tuple of (status, headers, response).

start_response and write are very annoying in WSGI middleware. wsgistraw makes your middleware code cleaner. This is an example of a “lowercase” middleware factory:

@wsgistraw.mid_factory
def lowercase(app):
    def mid(environ):
        status, headers, response = app(environ)
        return status, headers, (s.lower() for s in response)
    return mid
