I'm the guy who wrote the FTPClient class, so blame me if it's too hard :)
First I'll mention that the FTPClient in CVS has much better documentation
than the last release, so you might want to use that.
Are you familiar with the idea of a Protocol? If not, have a look at the
Writing Servers how-to:
The idea is that as the file is retrieved, you can use any arbitrary
Protocol you like to process it. For simply saving to disk, that could be:
from twisted.protocols.protocol import Protocol
def __init__(self, filename):
self.file = open(filename, 'w')
def dataReceived(self, data):
You could then instantiate this class and pass it as the second argument to
I probably should improve the ftpclient.py example to cover this, as it is a
fairly typical sort of use I imagine. Incidentally, does anyone know if
there is a FileWriterProtocol or similar already in Twisted somewhere? I
can't think of one off the top of my head.
