rename-after-writing 0.0.13

Path

Writes to a temporary path and move it to your desired path on exit.

import rename_after_writing as rnw

with rnw.Path(path="my_file.txt") as tmp_path:
    with open(tmp_path, "wt") as f:
        for i in range(10):
            f.write(input())

Note, that while you write to the file (while you provide input()) the file is written into a temporary file named path + . + uuid(). After writing, on exit of the contextmanager, the temporary file is moved to path.

open

Just like python’s built in open() but when writing (mode=w) everything is writen to a temporary file in the destination’s directory before the temporary file is renamed to the final destination.

import rename_after_writing as rnw

with rnw.open("my_file.txt", "wt") as f:
    for i in range(10):
        f.write(input())

copy

Copies the file first to a temporary file in the destinations directory before moving it to its final path.

import rename_after_writing as rnw

rnw.copy(src="machine/with/src", dst="other/machine/in/network/dst")

move

Some implementations of network-file-systems might raise an OSError with errno.EXDEV when an os.rename() is going across the boundary of a physical drive. In this case, this package’s copy is used to copy the file beore unlinking the source-file.

import rename_after_writing as rnw

rnw.move(src="machine/with/src", dst="other/machine/in/network/dst")
