Subset of the CPython module pathlib


Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.


Installing from PyPI
=====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-pathlib/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-pathlib

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-pathlib

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .env/bin/activate
    pip3 install adafruit-circuitpython-pathlib

Installing to a Connected CircuitPython Device with Circup
==========================================================

Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:

.. code-block:: shell

    pip3 install circup

With ``circup`` installed and your CircuitPython device connected use the
following command to install:

.. code-block:: shell

    circup install adafruit_pathlib

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    import adafruit_pathlib


    def print_directory_tree(path: adafruit_pathlib.Path, prefix: str = ""):
        """Recursively prints an ASCII tree of the given directory."""
        if not path.is_dir():
            print(f"{path} is not a directory.")
            return

        entries = sorted(path.iterdir(), key=lambda x: (not x.is_dir(), x.name.lower()))
        for index, entry in enumerate(entries):
            connector = "|-- " if index < len(entries) - 1 else "'-- "
            print(f"{prefix}{connector}{entry.name}")
            if entry.is_dir():
                extension = "|   " if index < len(entries) - 1 else "    "
                print_directory_tree(entry, prefix + extension)


    dir_path = adafruit_pathlib.Path("/lib")

    print_directory_tree(dir_path)
