A library for making atomic file writes. Basically it guarantees that the data is not partially written to the file (hence corrupting it in case an exception is raised) by writing to a temporary file that gets renamed and deleted after writing.
from atomicio.api import atomic_write
with atomic_write(path) as (r,w):
for item in r:
w.write(process(item))There are many other libraries that provide this functionality in
Python. This library's approach and API is inspired by fatomic
and python-atomicwrites respectively. So far atomicio has not
been tested on Windows but it shouldn't work because currently,
os.rename does not work on already created files.
