Fully adopt pathlib.PurePath for file paths
✨ Feature Request
Iris uses os.path
to handle file paths, but the standard in Python 3 is to use pathlib.PurePath
objects. #3411 proposed adopting pathlib.PurePath
and this is partially implemented by #3917. The present issue proposes replacing os.path
with the use of pathlib
across the whole of Iris.
Details
#3917 implements pathlib.PurePath
for the main public functions only (load
, load_cube
, load_cubes
, load_raw
and save
). See https://github.com/SciTools/iris/pull/3917#pullrequestreview-846736928 for full details of what has been done and what is still to do.
Is this actually closable now @SimonPeatman @wjbenfold ? Excuse my ignorance, I haven't been following detail here -- just tidying issues
No, @pp-mo, this is the issue that has come out of the recent work on pathlib. We've so far introduced it "superficially" - i.e. the most frequently used bits of the public api will now accept a pathlib path but it's almost immediately converted to a string. This ticket is for the further work that would use paths all the way down (maybe converting input strings to paths) and leverage the features of paths that we currently use os
for.
