Description:
aiopathlib 0.5.0
aiopathlib: Pathlib support for asyncio
aiopathlib is written in Python, for handling local
disk files in asyncio applications.
Base on aiofiles and just like pathlib, but use await.
with open('filename', 'w') as fp:
fp.write('My file contents')
text = await aiopathlib.AsyncPath('filename').read_text()
print(text)
'My file contents'
content = await aiopathlib.AsyncPath(Path('filename')).read_bytes()
print(content)
b'My file contents'
Asynchronous interface to create folder.
from aiopathlib import AsyncPath
apath = AsyncPath('dirname/subpath')
if not await apath.exists():
await apath.mkdir(parents=True)
Features
a file API very similar to Python's standard package pathlib, blocking API
support for buffered and unbuffered binary files, and buffered text files
support for async/await (:PEP:492) constructs
Installation
To install aiopathlib, simply:
$ pip install aiopathlib
Usage
These functions are awaitable
read_text
read_bytes
read_json
write_text
write_bytes
write_json
mkdir
touch
exists
rename
unlink
rmdir
remove
stat
lstat
is_file
is_dir
is_symlink
is_fifo
is_mount
is_block_device
is_char_device
is_socket
Example
Some common using cases:
from pashlib import Path
from aiopathlib import AsyncPath
filename = 'test.json'
ap = AsyncPath(filename)
p = Path(filename)
assert (await ap.exists()) == p.exists() == False
await ap.touch() # Create a empty file
assert (await ap.is_file()) == p.is_file() == True
assert (await ap.is_dir()) == p.is_dir() == False
assert (await ap.is_symlink()) == p.is_symlink() == False
for func in ('is_fifo', 'is_mount', 'is_block_device', 'is_char_device', 'is_socket'):
assert (await getattr(ap, func)()) == getattr(p, func)()
d = {'key': 'value'}
await ap.write_json(d) # == p.write_text(json.dumps(d))
assert (await ap.read_json()) == d # == json.loads(p.read_text())
assert (await ap.read_bytes()) == p.read_bytes() # b'{"key": "value"}'
assert (await ap.stat()) == p.stat()
assert (await ap.lstat()) == p.lstat()
ap = await ap.rename('test_dir') # == AsyncPath(p.rename('test_dir'))
await ap.remove() # == await ap.unlink() == p.unlink()
await ap.mkdir() # == p.mkdir()
# Synchronization functions
[Path(i) for i in ap.glob('*')] == list(p.glob('*'))
[Path(i) for i in ap.rglob('*')] == list(p.rglob('*'))
ap / 'filename' == ap.joinpath('filename') == AsyncPath(f'{ap}/filename')
str(AsyncPath('string-or-Path-or-AsyncPath')) == str(Path('string-or-Path-or-AsyncPath'))
ap.stem == p.stem
ap.suffix == p.suffix
Path(ap.with_name('xxx')) == p.with_name('xxx')
Path(ap.parent) == p.parent
Path(ap.resolve()) == p.resolve()
