pathvalidate v3.2.0
can do the following:
from pathvalidate import sanitize_filename, ValidationError
def add_trailing_underscore(e: ValidationError) -> str:
if e.reusable_name:
return e.reserved_name
return f"{e.reserved_name}_"
sanitize_filename(".", reserved_name_handler=add_trailing_underscore, additional_reserved_names=["."])
'._'
from pathvalidate.
Was this ever resolved? I have the same issue in 2.5.2
It would be great if sanitize_filename("..")
(or maybe sanitize_filename("..", check_reserved=True)
) returned "_
"
from pathvalidate.
I have considered this previously and concluded that it is difficult to apply replacements unconditionally.
Unlike other reserved words, .
and ..
can be assumed to be recognized as reserved keywords and used as reserved names in most cases, so I think it is inappropriate to treat them in the same way as other reserved words.
In many cases, users would expect to preserve .
and ..
as they are, and there is a possibility that the valid file paths are broken if they are replaced.
In the future, another solution may be to add an interface that specifies a callback function to process reserved names.
By customizing this callback function, changing the behavior as you wish will be possible.

I agree that they probably shouldn't be replaced in sanitize_filepath
since both .
and ..
are valid in relative paths. But personally I'm not sure I would expect them to ever be valid via sanitize_filename
since you cannot name a file .
or ..
.
I suppose if people are using sanitize_filename
to check individual path components then they might want to preserve periods.
