Reading a file from standardinput using ainput

[srbcheema1]

I have written a code that works on asyncio. In that code, I had to read a file from standard input using ./check.py < file.txt I am able to give input from the terminal. normally it works fine. But it doesn't work for reading data from a file from standard input.

#!/usr/bin/env python3.6

import asyncio
from aioconsole import ainput

async def read_input():
    while True:
        inp = await ainput()
        print('got ' + inp)

if (__name__ == "__main__"):
    asyncio.get_event_loop().run_until_complete(read_input())

normally it works like

$ ./check.py 
4
got 4
5
got 5

But while reading from file directly I face this log:

$ ./check.py  < test/test_case 
Traceback (most recent call last):
  File "./check.py", line 12, in <module>
    asyncio.get_event_loop().run_until_complete(read_input())

    return future.result()

    transport = self._make_read_pipe_transport(pipe, protocol, waiter)

    return _UnixReadPipeTransport(self, pipe, protocol, waiter, extra)
  File "/usr/lib/python3.6/asyncio/unix_events.py", line 353, in __init__
    raise ValueError("Pipe transport is for pipes/sockets only.")
ValueError: Pipe transport is for pipes/sockets only.

Unable to get why is it behaving differently? I want to read a file like ./check.py < file.txt using coroutines.
Thanks in advance :)

Thanks for the report @srbcheema1,

It turns out this issue has already been fixed in PR #25. It became visible in version 0.1.9 that I just released. Run pip3 install -U aioconsole and you should be good to go :)
