Summary

pathvalidate is a Python library to sanitize/validate a string such as filenames/file-paths/etc.

Features

• Sanitize/Validate a string as a:

  • file name

  • file path

• Multibyte character support

Examples

Sanitize a filename

Sample Code:

from pathvalidate import sanitize_filename

fname = "fi:l*e/p\"a?t>h|.t<xt"
print("{} -> {}".format(fname, sanitize_filename(fname)))

fname = "\0_a*b:c<d>e%f/(g)h+i_0.txt"
print("{} -> {}".format(fname, sanitize_filename(fname)))

Output:

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

Sanitize a filepath

Sample Code:

from pathvalidate import sanitize_filepath

fpath = "fi:l*e/p\"a?t>h|.t<xt"
print("{} -> {}".format(fpath, sanitize_filepath(fpath)))

fpath = "\0_a*b:c<d>e%f/(g)h+i_0.txt"
print("{} -> {}".format(fpath, sanitize_filepath(fpath)))

Output:

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

Validate a filename

Sample Code:

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(e, file=sys.stderr)

Output:

invalid char found: invalid-char=':, \*, /, ", \?, >, \|, <', value='fi:l*e/p"a?t>h|.t<xt', reason=ErrorReason.INVALID_CHARACTER

Check a filename

Sample Code:

from pathvalidate import is_valid_filename, sanitize_filename

fname = "fi:l*e/p\"a?t>h|.t<xt"
print("is_valid_filename('{}') return {}".format(fname, is_valid_filename(fname)))

sanitized_fname = sanitize_filename(fname)
print("is_valid_filename('{}') return {}".format(sanitized_fname, is_valid_filename(sanitized_fname)))

Output:

is_valid_filename('fi:l*e/p"a?t>h|.t<xt') return False
is_valid_filename('filepath.txt') return True
