:Sample Code: .. code-block:: python
from pathvalidate import sanitize_filename
fname = "fi:l*e/p\"a?t>h|.t<xt"
print(f"{fname} -> {sanitize_filename(fname)}\n")
fname = "\0_a*b:c<d>e%f/(g)h+i_0.txt"
print(f"{fname} -> {sanitize_filename(fname)}\n")
:Output: .. code-block::
fi:l*e/p"a?t>h|.t<xt -> filepath.txt
_a*b:c<d>e%f/(g)h+i_0.txt -> _abcde%f(g)h+i_0.txt
The default target platform is universal.
i.e. the sanitized file name is valid for any platform.
:Sample Code: .. code-block:: python
from pathvalidate import sanitize_filepath
fpath = "fi:l*e/p\"a?t>h|.t<xt"
print(f"{fpath} -> {sanitize_filepath(fpath)}\n")
fpath = "\0_a*b:c<d>e%f/(g)h+i_0.txt"
print(f"{fpath} -> {sanitize_filepath(fpath)}\n")
:Output: .. code-block::
fi:l*e/p"a?t>h|.t<xt -> file/path.txt
_a*b:c<d>e%f/(g)h+i_0.txt -> _abcde%f/(g)h+i_0.txt
:Sample Code: .. code-block:: python
import sys
from pathvalidate import ValidationError, validate_filename
try:
validate_filename("fi:l*e/p\"a?t>h|.t<xt")
except ValidationError as e:
print(f"{e}\n", file=sys.stderr)
try:
validate_filename("COM1")
except ValidationError as e:
print(f"{e}\n", file=sys.stderr)
:Output: .. code-block::
[PV1100] invalid characters found: platform=universal, description=invalids=('/'), value='fi:l*e/p"a?t>h|.t<xt'
[PV1002] found a reserved name by a platform: 'COM1' is a reserved name, platform=universal, reusable_name=False
:Sample Code: .. code-block:: python
from pathvalidate import is_valid_filename, sanitize_filename
fname = "fi:l*e/p\"a?t>h|.t<xt"
print(f"is_valid_filename('{fname}') return {is_valid_filename(fname)}\n")
sanitized_fname = sanitize_filename(fname)
print(f"is_valid_filename('{sanitized_fname}') return {is_valid_filename(sanitized_fname)}\n")
:Output: .. code-block::
is_valid_filename('fi:l*e/p"a?t>h|.t<xt') return False
is_valid_filename('filepath.txt') return True

parser = ArgumentParser()
parser.add_argument("--filename", type=validate_filename_arg)

.. note::
validate_filepath_arg consider platform as of "auto" if the input is an absolute file path.

from argparse import ArgumentParser

if options.filepath:

:Output: .. code-block::
$ ./examples/argparse_sanitize.py --filename e/g

.. note::
sanitize_filepath_arg is set platform as "auto".
