import sockets, os
##
## **Warning:** This module is deprecated since version 0.10.2.
## Use the brand new `asyncdispatch <asyncdispatch.html>`_ module together
## with the `asyncnet <asyncnet.html>`_ module.
## This module implements an asynchronous event loop together with asynchronous
## sockets which use this event loop.
## It is akin to Python's asyncore module. Many modules that use sockets
## have an implementation for this module, those modules should all have a
## ``register`` function which you should use to add the desired objects to a
## dispatcher which you created so
## that you can receive the events associated with that module's object.
##
## Once everything is registered in a dispatcher, you need to call the ``poll``
## function in a while loop.
##
## **Note:** Most modules have tasks which need to be ran regularly, this is
## why you should not call ``poll`` with a infinite timeout, or even a
## very long one. In most cases the default timeout is fine.
##
## **Note:** This module currently only supports select(), this is limited by
## FD_SETSIZE, which is usually 1024. So you may only be able to use 1024
## sockets at a time.
##
## Most (if not all) modules that use asyncio provide a userArg which is passed
## on with the events. The type that you set userArg to must be inheriting from
## ``RootObj``!
##
## **Note:** If you want to provide async ability to your module please do not
## use the ``Delegate`` object, instead use ``AsyncSocket``. It is possible
## that in the future this type's fields will not be exported therefore breaking
## your code.
##
## **Warning:** The API of this module is unstable, and therefore is subject
## to change.
##
## Asynchronous sockets
## ====================
##
## For most purposes you do not need to worry about the ``Delegate`` type. The
## ``AsyncSocket`` is what you are after. It's a reference to
## the ``AsyncSocketObj`` object. This object defines events which you should
## overwrite by your own procedures.
##
## For server sockets the only event you need to worry about is the ``handleAccept``
## event, in your handleAccept proc you should call ``accept`` on the server
## socket which will give you the client which is connecting. You should then
## set any events that you want to use on that client and add it to your dispatcher
## using the ``register`` procedure.
##
## An example ``handleAccept`` follows:
##
## .. code-block:: nim
##
## var disp = newDispatcher()
## ...
## proc handleAccept(s: AsyncSocket) =
## echo("Accepted client.")
## var client: AsyncSocket
## new(client)
## s.accept(client)
## client.handleRead = ...
## disp.register(client)
## ...
##
## For client sockets you should only be interested in the ``handleRead`` and
## ``handleConnect`` events. The former gets called whenever the socket has
## received messages and can be read from and the latter gets called whenever
## the socket has established a connection to a server socket; from that point
## it can be safely written to.
##
## Getting a blocking client from an AsyncSocket
## =============================================
##
## If you need a asynchronous server socket but you wish to process the clients
## synchronously then you can use the ``getSocket`` converter to get
## a ``Socket`` from the ``AsyncSocket`` object, this can then be combined
## with ``accept`` like so:
##
## .. code-block:: nim
##
## proc handleAccept(s: AsyncSocket) =
## var client: Socket
## getSocket(s).accept(client)

## This module **partially** implements an FTP client as specified

##
## This module provides both a synchronous and asynchronous implementation.
## The asynchronous implementation requires you to use the ``asyncFTPClient``
## function. You are then required to register the ``AsyncFTPClient`` with a
## asyncio dispatcher using the ``register`` function. Take a look at the
## asyncio module documentation for more information.
##
## **Note**: The asynchronous implementation is only asynchronous for long
## file transfers, calls to functions which use the command socket will block.
##
## Here is some example usage of this module:

## var ftp = ftpClient("example.org", user = "user", pass = "pass")
## ftp.connect()
## ftp.retrFile("file.ext", "file.ext")
