Smart dispatch between pathlib.Path and s3path.S3Path. It was borrowed from the project by EMTF: firstname.lastname@example.org
pathlib.Path if a local file system path is given,
s3path.S3Path if the given path is prefixed with
from smart_path import smart_path from pathlib import Path from s3path import S3Path # A local path on file system path_local = smart_path("/tmp/t") assert isinstance(path_local, Path) # A s3 path on oss path_brainpp_oss = smart_path("s3://public-datasets-contrib/", endpoint_url='s3.amazonaws.com') assert isinstance(path_local, S3Path)
from smart_path import smart_path # Stub mode works like the symbolic link in Unix. The source path can be either # on local file system or brain++ oss, so do the target path. Stub Mode is # excepted to be helpful when we need to store a large file on oss and pretend # it is on local file system. # # In stub mode, smart_path writes to two destinations: # 1. The string "hello-world" is written to `s3://somewhere/on/oss` # 2. The path "s3://somewhere/on/oss" is written to `corresponding/local/path` path = smart_path('s3://somewhere/on/oss', stub='corresponding/local/path') path.write_text('hello-world') # smart_path knows it is a stub file stub = smart_path('corresponding/local/path') print(stub.read_text()) # prints "hello-world"
pip install -e git://github.com/wanzysky/smart_path.git#egg=smart_path # Or from PyPI pip install smart_path
