Declerative resource management library for python

Examples

Closing Resources only on exception:

from pyraii.context import closing_on_exception

def wait_for_authenticated_client_connection():
    my_socket = wait_for_client_connection(*args)
    with closing_on_exception(my_socket):
        username = authenticate_connection(my_socket)
        return my_socket, username

Nothrow closing:

from pyraii.context import closing_nothrow

# If the file fails to close no exception will be thrown
with closing_nothrow(my_file):
    my_file.write(data)

Resource owning classes:

from pyraii.resource_owner import ResourceOwner

class Server(ResourceOwner):
    def __init__():
        self.socket_a = get_socket()
        self.socket_b = get_other_socket()
        self._log_file = open_log_file()
        self._data = "asdasd"
my_server = Server()
my_server.close() # will close all sockets and files which are members of the server
