Real asynchronous file operations with asyncio support.

Status

Development - Stable

Features

AIOFile has no internal pointer. You should pass offset and chunk_size for each operation or use helpers (Reader or Writer).
For POSIX (MacOS X and Linux) using implementaion based on aio.h (with Cython).
For non-POSIX systems using thread-based implementation

Code examples

All code examples requires python 3.5+.

Write and Read

import asyncio
from aiofile import AIOFile, Reader, Writer


async def main():
    async with AIOFile("/tmp/hello.txt", 'w+') as afp:
        await afp.write("Hello ")
        await afp.write("world", offset=7)
        await afp.fsync()

        print(await afp.read())


loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Write and read with helpers

import asyncio
from aiofile import AIOFile, Reader, Writer


async def main():
    async with AIOFile("/tmp/hello.txt", 'w+') as afp
        writer = Writer(afp)
        reader = Reader(afp, chunk_size=8)

        await writer("Hello")
        await writer(" ")
        await writer("World")
        await afp.flush()

        async for chunk in reader:
            print(chunk)


loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Read file line by line

import asyncio
from aiofile import AIOFile, LineReader, Writer


async def main():
    async with AIOFile("/tmp/hello.txt", 'w+') as afp
        writer = Writer(afp)

        await writer("Hello")
        await writer(" ")
        await writer("World")
        await writer("\n")
        await writer("\n")
        await writer("From async world")
        await afp.flush()

        async for line in LineReader(afp):
            print(line)


loop = asyncio.get_event_loop()
loop.run_until_complete(main())
