Features
---------
- Sanitize/Validate a string as a:
    - file name
    - file path
- Sanitize will do:
    - Remove invalid characters for a target platform
    - Replace reserved names for a target platform
    - Normalize
    - Remove unprintable characters
- Argument validator/sanitizer for ``argparse`` and ``click``
- Multi platform support:
    - ``Linux``
    - ``Windows``
    - ``macOS``
    - ``POSIX``: POSIX-compliant systems (Linux, macOS, etc.)
    - ``universal``: platform independent
- Multibyte character support

CLI tool
---------
You can find this package's command line interface tool at the `pathvalidate-cli <https://github.com/thombashi/pathvalidate-cli>`__ repository.

Examples
==========
Sanitize a filename
---------------------
: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.

Sanitize a filepath
---------------------
: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

Validate a filename
---------------------
: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

Check a filename
------------------
: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

filename/filepath validator for ``argparse``
----------------------------------------------
:Sample Code:
    .. code-block:: python

        from argparse import ArgumentParser

        from pathvalidate.argparse import validate_filename_arg, validate_filepath_arg

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

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

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

:Output:
    .. code-block::

        $ ./examples/argparse_validate.py --filename eg
        filename: eg
        $ ./examples/argparse_validate.py --filename e?g
        usage: argparse_validate.py [-h] [--filename FILENAME] [--filepath FILEPATH]
        argparse_validate.py: error: argument --filename: [PV1100] invalid characters found: invalids=(':'), value='e:g', platform=Windows

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

filename/filepath sanitizer for ``argparse``
----------------------------------------------
:Sample Code:
    .. code-block:: python

        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:
    .. code-block::

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

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

filename/filepath validator for ``click``
-------------------------------------------
:Sample Code:
    .. code-block:: python

        import click

        from pathvalidate.click import validate_filename_arg, validate_filepath_arg


        @click.command()
        @click.option("--filename", callback=validate_filename_arg)
        @click.option("--filepath", callback=validate_filepath_arg)
        def cli(filename: str, filepath: str) -> None:
            if filename:
                click.echo(f"filename: {filename}")
            if filepath:
                click.echo(f"filepath: {filepath}")


        if __name__ == "__main__":
            cli()

:Output:
    .. code-block::

        $ ./examples/click_validate.py --filename ab
        filename: ab
        $ ./examples/click_validate.py --filepath e?g
        Usage: click_validate.py [OPTIONS]
        Try 'click_validate.py --help' for help.

        Error: Invalid value for '--filename': [PV1100] invalid characters found: invalids=('?'), value='e?g', platform=Windows

filename/filepath sanitizer for ``click``
-------------------------------------------
:Sample Code:
    .. code-block:: python

        import click

        from pathvalidate.click import sanitize_filename_arg, sanitize_filepath_arg


        @click.command()
        @click.option("--filename", callback=sanitize_filename_arg)
        @click.option("--filepath", callback=sanitize_filepath_arg)
        def cli(filename, filepath):
            if filename:
                click.echo(f"filename: {filename}")
            if filepath:
                click.echo(f"filepath: {filepath}")


        if __name__ == "__main__":
            cli()

:Output:
    .. code-block::

        $ ./examples/click_sanitize.py --filename a/b
        filename: ab
