   You can adapt this file completely to your liking, but it should at least
   contain the root `toctree` directive.

ftp client/server for asyncio (https://aioftp.rtfd.io)

.. _GitHub: https://github.com/aio-libs/aioftp

Features
--------

- Simple.
- Extensible.
- Client socks proxy via `siosocks <https://github.com/pohmelie/siosocks>`_
  (`pip install aioftp[socks]`).

Goals
-----

- Minimum usable core.
- Do not use deprecated or overridden commands and features (if possible).
- Very high level api.

Client use this commands: USER, PASS, ACCT, PWD, CWD, CDUP, MKD, RMD, MLSD,
MLST, RNFR, RNTO, DELE, STOR, APPE, RETR, TYPE, PASV, ABOR, QUIT, REST, LIST
(as fallback)

Server support this commands: USER, PASS, QUIT, PWD, CWD, CDUP, MKD, RMD, MLSD,
LIST (but it's not recommended to use it, cause it has no standard format),
MLST, RNFR, RNTO, DELE, STOR, RETR, TYPE ("I" and "A"), PASV, ABOR, APPE, REST

This subsets are enough for 99% of tasks, but if you need something, then you
can easily extend current set of commands.

Server benchmark
----------------

Compared with `pyftpdlib <https://github.com/giampaolo/pyftpdlib>`_ and
checked with its ftpbench script. The ftpbench script is very old,
for python 3.12+ you need extra packages `pip install pyasyncore pyasynchat`

Client example

**WARNING**

For all commands, which use some sort of «stats» or «listing», ``aioftp`` tries
at first ``MLSx``-family commands (since they have structured, machine readable
format for all platforms). But old/lazy/nasty servers do not implement this
commands. In this case ``aioftp`` tries a ``LIST`` command, which have no
standard format and can not be parsed in all cases. Take a look at
`FileZilla <https://svn.filezilla-project.org/filezilla/FileZilla3/trunk/src/engine/directorylistingparser.cpp?revision=7322&view=markup>`_
«directory listing» parser code. So, before creating new issue be sure this
is not your case (you can check it with logs). Anyway, you can provide your own
``LIST`` parser routine (see the client documentation).

.. code-block:: python

    import asyncio
    import aioftp


    async def get_mp3(host, port, login, password):
        async with aioftp.Client.context(host, port, login, password) as client:
            for path, info in (await client.list(recursive=True)):
                if info["type"] == "file" and path.suffix == ".mp3":
                    await client.download(path)


    async def main():
        tasks = [
            asyncio.create_task(get_mp3("server1.com", 21, "login", "password")),
            asyncio.create_task(get_mp3("server2.com", 21, "login", "password")),
            asyncio.create_task(get_mp3("server3.com", 21, "login", "password")),
        ]
        await asyncio.wait(tasks)

    asyncio.run(main())

Server example

.. code-block:: python

    import asyncio
    import aioftp


    async def main():
        server = aioftp.Server([user], path_io_factory=path_io_factory)
        await server.run()

    asyncio.run(main())

Or just use simple server

.. code-block:: shell

    python -m aioftp --help
