> pathlib does not allow to distinguish "path" from "path/".
os.path.normpath() and os.path.abspath() don't retain a trailing slash -- or a
leading dot component for that matter. Are you referring to os.path.join()? For
example:
>>> os.path.join('./spam', 'eggs/')
'./spam/eggs/'
>>> os.path.normpath('./spam/eggs/')
'spam/eggs'
>>> PurePath('./spam') / PurePath('eggs/')
PurePosixPath('spam/eggs')
A leading dot component is significant in a context that searches a set of
paths -- usually PATH. A trailing slash is significant in a context that has to
distinguish a device or file path from a directory path, of which there are
several cases in Windows.
I think it's a deficiency in pathlib that it lacks a way to require
conservative normalization in these cases. Path and PurePath objects could gain
a keyword-only parameter, and internal attribute if needed, that enables a more
conservative normalization.
