4.8. filename/filepath validator for argparse

Sample Code

from argparse import ArgumentParser

from pathvalidate.argparse import validate_filename_arg, validate_filepath_arg

parser = ArgumentParser()
parser.add_argument("--filepath", type=validate_filepath_arg)
parser.add_argument("--filename", type=validate_filename_arg)
options = parser.parse_args()

if options.filename:
    print("filename: {}".format(options.filename))

if options.filepath:
    print("filepath: {}".format(options.filepath))

Output

$ ./examples/argparse_validate.py --filename eg
filename: eg
$ ./examples/argparse_validate.py --filepath e?g
usage: argparse_validate.py [-h] [--filepath FILEPATH] [--filename FILENAME]
argparse_validate.py: error: argument --filepath: invalid char found: invalids=('?'), value='e?g', reason=INVALID_CHARACTER, target-platform=Windows

Note

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

4.9. filename/filepath sanitizer for argparse

Sample Code

from argparse import ArgumentParser

from pathvalidate.argparse import sanitize_filename_arg, sanitize_filepath_arg


parser = ArgumentParser()
parser.add_argument("--filename", type=sanitize_filename_arg)
parser.add_argument("--filepath", type=sanitize_filepath_arg)
options = parser.parse_args()

if options.filename:
    print("filename: {}".format(options.filename))

if options.filepath:
    print("filepath: {}".format(options.filepath))

Output

$ ./examples/argparse_sanitize.py --filename e/g
filename: eg

Note

sanitize_filepath_arg is set platform as "auto".
