AsyncLocalFileSystem

Extended version of LocalFileSystem that also provides async methods.

import asyncio
from morefs.asyn_local import AsyncLocalFileSystem

async def main():
    fs = AsyncLocalFileSystem(auto_mkdir=False)

    f = await fs.open_async("foo", mode="w")
    async with f:
        await f.write("foobar")

    content = await fs._cat("foo")
    print(content)
    print(fs.cat("foo"))  # you can still use sync methods

asyncio.run(main())

DictFS

DictFS is a nested dictionary-based, in-memory filesystem and acts more like a real LocalFileSystem.

from morefs.dict import filesystem

fs = DictFS()

MemFS

MemFS is a trie-based in-memory filesystem, and acts like a bucket storage.

from morefs.memory import MemFS

fs = MemFS()

OverlayFileSystem

from morefs.overlay import OverlayFileSystem

# use localfilesystem for write, overlay all filesystems for read
fs = OverlayFileSystem(file={"auto_mkdir": True}, s3={"anon": True})
# or you can pass filesystem instances directly
# as variable positional arguments or with keyword argument `filesystems=[]`
fs = OverlayFileSystem(LocalFileSystem(), s3={"anon": True})
